Abstract
The invention discloses a composite PVC (Polyvinyl Chloride) carpet and a manufacturing method of the same. The PVC carpet consists of a PVC meshed fabric, a PVC core-spun gauze and melt-blown superfine fiber, wherein the melt-blown superfine fiber is sandwiched between the PVC meshed fabric and the PVC core-spun gauze, and is formed by blending PP (Polystyrene), EVA (Ethylene Vinyl Acetate) and PVC. The manufacturing method comprises the following steps of: blending the PP and the EVA in a proper proportion; doping a certain PVC in the blend; melting granules of the three polymers by using a screw extruder; spraying the superfine fiber through a melt-blown assembly to attach surfaces of the PVC meshed fabric and the PVC core-spun gauze; and thermally forming and coiling the superfine fiber after being rolled by a hot roller before the superfine fiber is uncured. The composite PVC carpet has the advantages of high air permeability, elastic recovery and peeling strength; and no pollutant is discharged during the manufacturing process.
Description
Technical field
The present invention relates to a kind of composite PVC carpet and preparation method thereof, particularly prepare the composite PVC carpet about a kind of bonding method of three-phase condensate blend melt-blown micro fibre that adopts.
Background technology
Can know the composite PVC carpet from existing public technology, mostly adopt the bonding two-layer or two-layer above blanket cloth of chemical glue.
Chinese patent CN1234333 discloses the processing method of double-side composite carpet, mainly is to be coated with last layer glue on two measure-alike carpet back side base fabrics, and two layers of cloth is bonding, is the base fabric of two sides bonding in the middle of the product.
Chinese patent CN2490022 discloses the characteristic of composite carpet: be by polyvinyl chloride (PVC) top layer and chemical crosslinking polyvinyl chloride bottom bonding the forming of hot melt class glue-line through the centre.
Chinese patent CN201533745; Open PVC flocked carpet; Comprise coiled material PVC basic unit and tapetum; Said coiled material PVC basic unit is by a PVC foaming layer, the glass fiber mesh layer of cloth, and the 2nd PVC foaming layer and PVC anti-slip bottom layer are formed; Said glass fiber mesh layer of cloth is sandwiched between first and second PVC foaming layer; The PVC anti-slip bottom layer is fixed in the 2nd PVC foaming layer lower surface, and said coiled material PVC basic unit upper surface scribbles the flocking glue-line, and said tapetum sticks at coiled material PVC basic unit upper surface through the flocking glue-line.
European patent EP O590422AL discloses the manufacturing approach of cloth shape carpet, and the finish coat of this carpet is by polyamide fibre, acrylic fibers, polypropylene fibre and the wool layer that is adhesively fixed; The adhesion heat melten gel is made up of ethylene copolymer emulsion glue and polyvinyl chloride (PVC) plastisol.
Visible from prior art and market product, the composite PVC carpet all adopts chemical adhesive to connect, and can distribute the gas of harmful health; Secondly, the compound hot-rolling of adhesive rolls formation face contact between the blanket cloth of back, has blocked the hole between the layer of cloth, and the composite carpet air penetrability is descended, and is prone to grow acarid, and the carpet elastic recovery rate is low in addition; Once more, the compound blanket that this kind method is produced is peeled off low by force, damages easily.
Summary of the invention
Technical problem to be solved by this invention provides does not have chemical adhesive in a kind of manufacture process, the composite PVC carpet and the manufacturing approach thereof of the discharging of pollution-free gas, and the carpet air penetrability is good simultaneously, and elastic recovery rate is high, and peel strength is high.
For solving the problems of the technologies described above, technical scheme of the present invention is:
Technical scheme of the present invention is with the PP of high fusion index and EVA blend and mix a certain amount of PVC in proportion; The pellet of these three kinds of polymer by the screw extruder fusion after; Spray superfine unformed, the superfine fibre that do not have orientation through melting and spraying assembly up and down; Stick to the covering yarn cloth surface of screen cloth and the PVC of PVC, uncured before, roll after heat typing shaping and batch by hot-rolling.The composite PVC carpet that makes thus comprises PVC screen cloth, PVC covering yarn cloth and is clipped in PP, EVA and PVC melt-blown micro fibre wherein.
Techniqueflow sketch map of the present invention is like figure;
Preferred 150～the 800g/10min of the melt index of said PP.
Preferred 60～320 g/10min of the melt index of said EVA.
Preferred 1.5～10 g/10min of the melt index of said PVC.
Said blend is that PP, EVA, PVC are the preparatory stirrings of three kinds of pellets before the input screw extruder.
Said blending ratio is weight percentage, preferred PP 65～80 ﹪, EVA 15～25 ﹪, PVC 5～10 ﹪.
The preferred cortex of said PVC covering yarn is PVC, and sandwich layer is the PET long filament.
110～150 ℃ of the preferred preheating zones of melt temperature that melts and sprays screw extruder of the present invention, 145～200 ℃ of melting zones, 150～205 ℃ of compressional zones, 150～200 ℃ of metering zones.
The assembly that melts and sprays of the present invention, preferred spinneret orifice number is 300～600 holes, aperture 0.12～0.22 ㎜, draw ratio 1:12～1:16.
Preferred 300～the 700MPa of pressure that melts and sprays of the present invention.
Preferred 180～230 ℃ of hot stream temperature of the present invention.
Preferred 15～the 65MPa of hot-rolling pressure of the present invention, preferred 105～175 ℃ of heat roller temperature.
Preferred 3～10 minutes of heat-setting time of the present invention, preferred 70～150 ℃ of heat setting temperature
The invention has the beneficial effects as follows:
1, the melt-blown micro fibre after PP, EVA, the PVC blend is a kind of physical adherence to the bonding of each layer of composite PVC carpet cloth, can not produce pernicious gas.
2, the point that between layer of cloth, forms of superfine fibre is bonding, and be characterized in: bounding point is many, and air penetrability is high, and the carpet elastic recovery rate is high.
3, the polymeric acceptor of three kinds of blend has made up that PP flows, the EVA cementability is good, the advantage of PVC and blanket cloth compatibility, so the bonding PVC composite carpet of the melt-blown micro fibre layer of cloth that this polymer blend forms is very firm, and peel strength is high.
