(:1.
- this invention is concerned with the art of forming said traffic regulating lines or signs by laying on and adhesively securing to a preliminarily prepared road a strip material having a lower face adapted forjuxtaposition and adhesive connection to a prepared and essentially smoothed area of the road blanket and an upper face for forming the sign and possessing suitable properties for good visibility. wear resistance and so onv b.
- the Prior Art These methods are well known in the art and widely published.
- the use of factory made strip materials, which can be stocked in coiled bobbins. carried to the locations where the traffic regulating sign is to be formed on a road surface and then un-wound to progressively lay the material on such surface. is very advantageous.
- the road surface preparation and the laying down of the materials can be mechanically made with a minimum of traffic disturbance.
- the strip material is essentially of elasto-plastic nature and its body may be formed from a variety of compositions. Examples of such compositions have been described. among other publications. in the Applicants prior US. Pat. No. 3.587.415. where the compositions for forming the base strip" have been described. In this latter patent specification there has been described also how the upper face of the strip material can be advantageously provided with means for improving its anti-skid properties and its nightime visibility. Other means for further improving the above and other properties have been made open to public inspection and knowledge by the French Pat. Publications No. 2.085.900. No. 2.086.257 and No. 2.097.941.
- the prior art includes preferably the provision of means for applying to the upper face of the prepared road blanket or preferably to the lower face of the strip material a thin layer of highly viscous adhesive.
- This provision requires rather costly and complicated means and devices and a very careful control and operation of such devices and of the means provided for applying and spreading the adhesive on such face in measured amount.
- This method is also seriously objectionable both because this surface is extremely receptive to dirt. sand. powder and so on. and because the primer layer. the width of which is necessarily larger than the sign forming strip or tape material. will form on the road surface sticky portions at either side of the applied tape material.
- the sign forming tape material is provided. at its face designed to be contacted with. juxtaposed and pressed on the upper face of the prepared road surface. with a layer of a compound which is not sticky at least at ambient temperature. but capable of providing an adhesive bond with the upper surface of the primer layer on the road. upon a physical and/or a chemical modification occurring in the compound adjacent to the tape material primer layer interface and promoted by actual contact and pressure of said sign forming tape material on said primer layer. said modification occurring by an interexchange originated by said actual contact and occurring through said interface.
- the said tape material having a visible sign actuating upper face.
- the said potentially adhesive lower layer comprises a thermoplastic resinous component capable of acquiring adhesive properties if thermally plastified. and the tape material is laid on and pressed over a preliminarily heated primer layer to promote a heat exchange at said interface. leading to an adhesive bond between said lower layer of the tape material and the primer layer on the road surface.
- the preliminary heating of the primer layer is preferably provided by forming said primer layer of a meltable compound and laying the molten compound on the road surface blanket and then laying the tape material on the still hot primer layer.
- the said potentially adhesive lower layer comprises a resinous component capable of chemically reacting in particular to cross-link with another component present in the primer layer composition to provide the desired physical bond at said interface.
- a heat inter'exehange at said interface can be preferably provided for promoting and/or accelerating the chemical reaction.
- the said potentially adhesive lower layer comprises a resinous component capable of acquiring sticky properties when partially dissolved by compatible solvents. and the tape material is laid on and pressed against a primer layer including an excess of at least one of said compatible solventsv
- Further embodiments of the invention comprise combinations of the above indicated modes for providing a bond forming inter-exchange at the interface provided by the actual juxtaposition and pressure of the potentially adhesive lower layer preliminarily and factory provided at the lower face of the tape material on the upper face of a primer layer preliminarily provided on the selected area of the road surface to be marked.
- the said lower layer is made of a compound including preferably a synthetic rubber.
- the primer layer is made. according to current art. of a compound prevailingly consisting of bitumen and it is applied on and smoothed over the road blanket, also according to current art. in its molten or fluidificd state. and the tape material is laid thereon when the said primer layer is still hot.
- the said primer layer has preferably the following composition. in parts by weight:
- the said potentially adhesive layer has preferably the following composition. in parts by weight also:
- the interfacial bond is prevailingly provided by a chemical cross-linking promoted between resinous components appertaining to the potentially adhesive lower layer and respectively to the primer layer.
- Such components consist of like resins or of resins of similar nature and capable of cross-linkage.
- the resinous component in the said lower layer is selected from those wherein a suitable hardener (provided in the compound of the primer layer) is highly soluble.
- a suitable hardener provided in the compound of the primer layer
- the said hardener is at least partly transferred through the interface and promotes the cross-linking of such resinous component. leading to the desired physical bond of the tape on the primer layer. upon a chemical action.
- reaction promoters being chosen from those capable of co-reacting and operating synergically.
- said promoters being individually present in the said potentially adhesive layer and primer layer. so that their co-action and synergy can be originated by the actual contact between the tape material and the primer layer only.
- the potentially adhesive lower layer of the tape material is preferably compounded as follows. in parts by weight:
- the primer layer is preferably compounded as follows. in parts by weight:
- the potentially adhesive lower layer of the tape material can be provided by making use of either of the compounds described in the Examples 1 or 2.
- the layer is factory applied to the lower face of tape (or stock sheet) body, upon plasticization of the compound by means of suitable solvents. according to current art. These solvents are eliminated until the lower face of the tape is no longer tacky. preliminarily to winding the tape onto bobbins for storage. transportation and application on the road surface.
- the ability to adhesively connect itself to the primer layer. by part of the tape lower layer. is restored by adding to said lower layer a certain amount of solvent equal or equivalent to those used for plasticizing the compound. said solvent being present. as an excess of solvent. in the primer layer.
- methylene chloride can be made use of as a plasticizing solvent for the potentially adhesive lower layer of Example 1. such chloride being itself the solvent for the primer layer of same Example 1.
- the solvent is provided in a greater amount. that is in excess. in the primer layer compound. for providing the excess which will be transferred. through the interface. from the primer layer to the lower face of the tape material laid on and pressed upon said primer layer. the compound of which comprising. in this occurrence. from 50 to 60 parts by weight of methylene chloride.
