Definitions
- This invention relates to adhesive bonding, and, more particularly, to a method of depositing an attenuable, aqueous polymeric dispersion or emulsion in a spiral spray pattern of elongated adhesive strands or fibers onto a first substrate for subse ⁇ quent bonding to a second substrate.
- thermoplastic adhesives There are a number of industrial applica- tions for adhering different types of products. In applications wherein quick setting time is desirable, hot melt thermoplastic adhesives have been widely used.
- the strength of the bond obtained with hot melt thermoplastic adhesives is determined, at least in part, by the area of interface or surface contact between the adhesive and substrate, i.e., the greater the area of contact, the stronger the bond.
- hot melt adhesives have been dispensed in a thick, extruded bead, which, because of the relatively high viscosity and high surface tension of such adhesives, is difficult to spread over as large a surface area as desired.. Additionally, hot melt adhesive cools quite quickly when it is applied to a substrate which further adds to the difficulty of spreading a bead over a larger area.
- hot melt adhesives Another problem with hot melt adhesives is that some substrates to be bonded are heat sensitive and can be damaged or destroyed by contact with hot melt adhesives which can have an application tempera ⁇ ture of 300°F or higher. This is of particular concern in applications such as the bonding of the polyethylene backing sheet to the non-woven pad of hygienic articles wherein the backing sheet is heat sensitive and can be damaged, or its appearance adversely affected, by relatively thick, high tempera ⁇ ture beads of hot melt adhesive.
- hot melt thermoplastic adhesives in an elongated, thin bead or fiber which is deposited atop the substrate.
- Elongated beads or fibers of adhesive have been produced in prior art spray devices which include a nozzle formed with an adhesive dis- charge opening and one or more air jet orifices through which a jet of air is ejected.
- a bead of adhesive is extruded from the adhesive discharge opening in the nozzle which is then impinged by the air jets to attenuate or stretch the adhesive bead forming an elongated, thin fiber for deposition onto the substrate.
- This elongated, thin strand or fiber of adhesive has a reduced application temperature compared to that of a relatively thick, extruded bead.
- spray devices capable of forming adhesive fibers are disclosed in U.S. Patent Nos. 2,626,424 to Hawthorne, Jr.; 3,152,923 to Marshall et al; 4,185,981 to Ohsato et al; and, Patent Nos. 3,911,173; 4,031,854; and, 4,098,632 all to Sprague, Jr.
- Water-based adhesives or so-called "cold adhesives” have been proposed as alternatives to hot melt thermoplastic adhesives in some applications, but were never considered as candidates for the formation of elongated, thin adhesive strands or fibers. This is due, in part, to the fact that water-based adhe ⁇ sives do not have the inherent disadvantages of hot melt adhesives which were the motivating factors in forming hot melt adhesives in elongated strands or fibers. Water-based adhesives are dispensed at ambient temperatures and therefore the problem of thermal damage to a substrate is eliminated. More ⁇ over, water-based adhesives do not cool when applied to a substrate, unlike hot melt adhesives which quickly cool and thereafter become more difficult to spread.
- water-based adhesives comprise a dispersion or emulsion of polymeric particles in an aqueous carrier, it was expected that any attempt to form elongated adhesive fibers from water-based adhesives, in the same manner as hot melt adhesives, would either produce adhesive droplets or break up the emulsion.
- This objective is accomplished in a method of bonding wherein an aqueous polymeric dispersion or emulsion, i.e., a water-based adhesive, is extruded in a bead from the discharge outlet of a dispensing device.
- This extruded bead of water-based adhesive is then attenuated by one or more jets of air ejected from air jet bores in the dispensing device to form an elongated adhesive strand or fiber having a small diameter compared ' to that of the extruded bead.
- these air jets contact the extr ded bead along its periphery to impart a swirling or twisting motion to the attenuated, elongated adhesive strand or fiber thereby forming a spiral spray pattern on a first substrate for subsequent bonding to a second substrate.
- the dis ⁇ pensing device In one aspect of this invention, it has been found that several operating conditions of the dis ⁇ pensing device must be controlled to obtain relatively- thin, elongated adhesive fibers in an acceptable pattern from certain types of water-based adhesives. These parameters include the diameter of the adhesive discharge outlet of the dispensing device from which the adhesive bead is extruded, the hydraulic pressure required to extrude an adhesive bead from the dis- charge outlet at a given weight per unit of time, e.g., grams per second, and the pressure of the air delivered to the air jet bores of the dispensing device for discharge of the air jets which impact the adhesive bead.
- these parameters include the diameter of the adhesive discharge outlet of the dispensing device from which the adhesive bead is extruded, the hydraulic pressure required to extrude an adhesive bead from the dis- charge outlet at a given weight per unit of time, e.g., grams per second, and the pressure of the air delivered to the air jet bores of the dispensing device for discharge of
- water-based adhesives are unacceptable for use in forming elongated adhesive fibers or strands without modification.
- One group of water-based adhesive e.g., ethylene vinyl acetate emulsions those having a viscosity of more than about 10,000 cps, tend to break up into non-uniform blobs and broken strings when ejected from the discharge outlet of the spray device.
- the operating conditions of the dispenser which have been employed to obtain acceptable adhesive fibers using these types of adhesives include a discharge outlet diameter in the range of about 0.016 to 0.030 inches, a hydraulic pressure of the adhesive delivered to the discharge outlet in the range of about 100 to 200 psi and a pressure of the air delivered to the air jet bores in the dispenser in the range of about 2 to 6 psi.
- other aqueous polymeric emulsions or dispersions e.g., styrene butadiene, do not form uniform elongated adhesive fibers at the desired viscosity level.
- the water-soluble polymer creates a continuous polymer phase between the particles of styrene butadiene which is capable of supporting the elongational stress applied to the extruded bead by the air jets to form an attenuated adhesive fiber instead of breaking up into droplets.
- the operating conditions of the dispenser employed to obtain an acceptable adhesive strand or fiber include a dis ⁇ charge outlet diameter of the dispenser in the range of about 0.016 to 0.030 inches, a hydraulic pressure of the adhesive delivered to the discharge outlet of about 40 psi and a pressure of the air delivered to the air jet bores in the dispenser of about 3 psi.
- Fig. 1 is a schematic, elevational view of a dispensing device for attenuating water-based adhe- sives
- Fig. 2 is an enlarged cross sectional view of that portion of the dispenser through which the water-based adhesive is extruded and impacted with air jets;
- Fig. 3 is a view of the pattern of elongated adhesive strands or fibers on a first substrate in preparation for bonding to a second substrate.
- a dispensing device or dispenser 10 is schematically illustrated which is capable of extruding an adhesive bead 12 and impacting the adhesive bead 12 with air jets 14 to form an attenuated or elongated adhesive strand or fiber 16.
- the details of the operation of dispenser 10 form no part of this invention per se and thus are described briefly herein.
- a complete discussion of the operation of dispenser 10 is given in U.S. Patent No. 4,785,996 to Ziecker et al, assigned to the same assignee as this invention, the disclosure of which is incorporated by reference in its entirety herein.
- the dispenser 10 has a dispenser body 18 which is con ⁇ nected by a line 20 to a source of water-based adhe ⁇ sive (not shown) , and by a line 22 to a source of pressurized air (not shown) .
- the base of the dispen ⁇ ser body 18 mounts a nozzle 23 which supports a nozzle plate 24 having a throughbore 26 which communicates with an adhesive passageway within the dispenser 10.
- the throughbore 26 terminates in a discharge outlet 28 through which the adhesive bead 12 is extruded, and has a length of about 0.125 inch.
- the nozzle plate 24 is also formed with six air jet bores 30, two of which are shown in Fig. 2, each having a length of about 0.050 inch and a diame ⁇ ter of about 0.018 inch. These air jet bores 30 communicate with an air delivery passageway formed in the dispenser body 18 and discharge individual jets 14 of pressurized air at an angle with respect to the longitudinal axis of the throughbore 26, and substan ⁇ tially tangent to the periphery of the adhesive bead 12 extruded from the throughbore 26.
- These air jets 14 are effective to both attenuate or stretch the adhesive bead 12 to form the thin, elongated adhesive fiber 16, and to impart a twisting or swirling motion to the adhesive fiber 16 so that the adhesive fiber 16 is laid down in a spiral pattern 31 upon a first substrate 32. See Fig. 3.
- the first substrate 32 can then be brought into contact with a second substrate 34 to form a bond therebetween, as illustrated sche ⁇ matically in Fig. 3.
- water-based adhesive as used herein is meant to refer to an aqueous polymeric dispersion or emulsion consisting of a polymeric material and water carrier, usually with a surfactant or other additives as is well understood in the art.
- the polymeric material or base can consist of any of the following: polyvinyl acetate, ethylene vinyl acetate, -ethylene and acrylic polymers, polyvinyl chloride, butadiene acrylonitrile, butadiene styrene, butyl, ethylene propylene polymers, fluoro polymers, natural rubber, polybutadiene, polychloroprene, polyisobutylene, polyisoprene, polysulfide, poly- urethane, silicone, and miscellaneous polymers.
- these aqueous polymeric emulsions have a solids content in the range of about 30% to 75%, and more preferably in the range of about 50% to 66%, by weight.
- water-based adhesive is also meant to refer to an aqueous polymeric emulsion or dispersion of the type described above with the addition of a water-soluble polymer such as hydroxypropyl methyl cellulose.
- this type of “water-based adhesive” employs the water-soluble polymer as an extender to create a continuous polymer phase with the polymer particles in the water carrier and thereby prevent the emulsion or dispersion from breaking up under the influence of elongational forces applied by the air jets 14 to the extruded bead 12 so as to permit the formation of an elongated adhesive fiber 16.
- an acceptable adhesive pattern 31 of elongated adhesive fibers 16 has been obtained.
- Example 1-5 a copolymer ethylene vinyl acetate emulsion was used having a viscosity in the range of about 800 to 1,200 centipoise (cps) and a solids content of about 66%, which is commercially available from Air Products and Chemicals, Inc. under the designation 465 DEV. The viscosity was measured using a Brookfield visco- eter. Model LVF (No. 3 spindle, 60 rpm, at 77°F).
- Example 1 polymer base ethylene vinyl acetate viscosity: 800 - 1,200 cps hydraulic pressure: 500 psi air jet pressure: 2 psi increased to 30 psi nozzle diameter: 0.012
- the air jet pressure was increased from about 2 psi to about 30 psi, holding all the other parameters constant, which produced acceptable elongated adhesive fibers 16 at pattern widths on the substrate ranging from about 0.125 inch at 2 psi to about 0.825 inch at 30 psi.
- the air jet pressure was increased from about 2 psi to about 30 psi, holding all the other parameters constant, which produced acceptable elongated adhesive fibers 16 at pattern widths on the substrate ranging from about 0.468 inch at 2 psi to about 0.563 inch at 30 psi with a maximum pattern width of 0.938 inch at 15 psi.
- the air jet pressure was increased from about 2 psi to about 30 psi, holding all the other parameters constant, which produced acceptable elongated adhesive fibers 16 at pattern widths on the substrate ranging rom about 0.313 inch at 2 psi to about 0.750 inch at 30 psi.
- Example 4 polymer base: ethylene vinyl acetate viscosity: 800 - 1,200 cps hydraulic pressure: 150 psi air jet pressure: 2 psi increased to 30 psi nozzle diameter: 0.018 inch
- the air jet pressure was increased from about 2 psi to about 30 psi, holding all the other parameters constant, which produced acceptable elongated adhesive fibers 16 at pattern widths on the substrate ranging from about 0.563 inch at 2 psi to about 1.00 inch at 30 psi with a maximum pattern width of 1.125 inch at 15 psi.
- Example 5 polymer base: ethylene vinyl acetate viscosity: 800 - 1,200 cps hydraulic pressure: 50 psi air jet pressure: 4 psi nozzle diameter: 0.020 inch Under these conditions, an acceptable elongated adhesive fiber 16 was produced on a sub ⁇ strate.
- Pattern widths were obtained from the operating conditions of Examples 1-5 in the range of about .125 inch to 1.125 inches.
- ethylene vinyl acetate emulsion was employed which is commercially available from National Starch and Chemical Corporation under the designation Impervo 14-9004.
- This ethylene vinyl acetate-based adhesive has 60% solids and a viscosity of 35,000 cps. It was discovered that such water-based adhesive produced droplets or blobs when extruded from the discharge outlet 28 of nozzle plate 24 and not a continuous extruded bead.
- elon ⁇ gated adhesive fibers 16 could be produced from this type of ethylene vinyl acetate emulsion by diluting the emulsion with de-ionized water. Additional experiments were conducted in which de-ionized water was added to the National Starch and Chemical Corporation adhesive designated Impervo 14-9004 in an effective amount to reduce the viscosity of the emulsion from 35,000 cps to a range of about 1,000 to 10,000 cps and most preferably to a range of about 800 to 6,000 cps. Specific results of such experiments are given in Examples 6, 7 and 8 below.
- Example 7 polymer base: ethylene vinyl acetate viscosity: 3,200 cps hydraulic pressure: 100 - 200 psi jet pressure: 2 - 4 psi nozzle diameter: 0.016 to 0.030 inches Under these conditions, a stable pattern 31 of an elongated adhesive fiber 16 was obtained on a substrate located at about 1 inch from the discharge outlet 28. The width of the pattern 31 was about 0.9 inches.
- Example 8 polymer base: ethylene vinyl acetate viscosity: 6,000 cps hydraulic pressure: 200 psi air jet pressure: 6 psi nozzle diameter: 0.016 to 0.030 inch
- This combination oi parameters produced a very fine elongated adhesive fiber 16 having a pattern width of about 0.8 inch.
- water-based adhesive as used herein is also meant to refer to an aqueous polymeric dispersion or emulsion of polymeric particles in a water medium with the addition of a water-soluble polymer in amounts in the range of about 0.25% to 5% by weight. It has been found that water- based adhesives with certain polymer bases are incap ⁇ able of sustaining the elongational forces applied by the air jets discharged from air jet bores 30 and tend to break up in coarse droplets or blobs at the desired viscosity without the addition of a continuous polymer phase with the particles of the polymer base so that the emulsion or dispersion can sustain such forces.
- a water-based adhesive with a water-soluble polymer additive which has been success ⁇ fully attenuated to form acceptable elongated adhesive fibers 16 is as follows.
- a water- based adhesive was employed which is commercially available from National Starch and Chemical Corpora ⁇ tion under the designation 33-4037.
- This adhesive has a styrene butadiene polymer base.
- the virgin adhesive 33-4037 has 60% solids and a viscosity of 9,000 cps which was diluted with water and 1% hydroxypropyl methyl cellulose to a viscosity of about 3,000 cps in the Example given below.
- Example 9 polymer base: styrene butadiene water-soluble polymeric additive: 1% hydroxypropyl methyl cellulose viscosity: 3,000 cps hydraulic pressure: 40 psi air jet pressure: 3 psi nozzle diameter: 0.016 to .030 inches
- an aqueous polymeric dispersion or emulsion having styrene butadiene as the polymer base when diluted with an effective amount of 1% hydroxypropyl methyl cellulose, was used effec ⁇ tively in the formation of elongated adhesive fibers 16 under the operating conditions of the dispenser 10 given above. It is believed that the 1% hydroxypropyl methyl cellulose is effective to provide a continuous polymeric phase between the particles of styrene butadiene within the water matrix so as to permit such dispersion or emulsion to sustain the elongational force imposed by the impact of the air jets 14 and thus permit the successful formation of an elongated adhesive bead 16. While 1% hydroxypropyl methyl cellulose was employed in this Example, it is contem ⁇ plated that this or another water-soluble polymer could be employed in a concentration in the range of about 1/4% to 5% by weight.
- an "elongated adhesive fiber 16" is formed which is identified as having a diameter comparatively smaller than that of the extruded bead 12.
- elongated adhesive fibers 16 have been produced from the method and under the conditions described above having a diameter in the range of about 0.008 to 0.0055 inch.
- the elongated adhesive fiber 16 tends to fuse together in the spiral pattern 31 making it difficult to accu ⁇ rately measure the diameter of the fiber 16.
- the air jets 14 which impinge the extruded bead 12 in terms of air pressure, e.g., 2 to 30 pounds per square inch.
- air pressure e.g. 2 to 30 pounds per square inch.
- the diameter of the air jet bores 30 in nozzle plate 24 are in the range of about 0.017 to 0.019 inches. The velocity of the air jets 14 discharged therefrom can therefore be calculated or measured.
