Abstract
The utility model relates to a PET light reflecting membrane, belonging to the technical field of membrane material. The PET light reflecting membrane comprises a PET surface layer (1), a PET intermediate layer (2) and a PET bottom layer (3) which are arranged sequentially, wherein the surface of the PET bottom layer (3) is sequentially provided with a light reflecting layer (4), a pressure sensitive adhesive layer (5) on which glass beads (5.1) are densely distributed and a protective layer (6). The PET light reflecting membrane using PET three-layer co-extrusion film as base material has good corrosive resistance and achieves great adhesiveness as the glass beads are adhered through the pressure sensitive adhesive layer, so the light reflecting membrane is hardly peeled off, the butyral protective layer has strong weatherability, and the service life of the PET light reflecting film is greatly prolonged by means of the co-action of materials of various layers.
Description
(1) technical field
The utility model relates to a kind of PET reflective membrane, is mainly used in the reflective of traffic safety facilities alarming sign.Belong to technical field of polymer materials.
(2) background technology
Along with improving constantly of China's living standards of the people, society's vehicle owning amount is per capita also increasing sharply, and the traffic accident incidence that can thereupon bring is also in rising trend.In traffic accident, the variation that is subjected to the harsh climate environment owing to the road traffic reflecting marking with paste damage that the reason that is connected causes, come off, and surperficial weatherability difference and lose the reflecting effect of sign.
Chinese patent CN201259556Y has announced a kind of reflective membrane, it is made up of the resin bed that sets gradually, polyester resin layer, soot layer, focus layer, metallic reflector, pressure-sensitive adhesive layer and separate paper, its surface has that adhesion is strong, the characteristics of good weatherability, but adhesive fastness is poor between polyester resin layer and the soot layer, come off easily, thus reduction of service life.
(3) summary of the invention
The purpose of this utility model is to overcome above-mentioned deficiency, and the PET reflective membrane of a kind of good weatherability, long service life is provided.
The purpose of this utility model is achieved in that a kind of PET reflective membrane; it comprises PET surface layer, PET intermediate layer and the PET bottom that sets gradually; it is characterized in that: described PET bottom surface is disposed with reflector layer, pressure-sensitive adhesive layer and protective layer, is densely covered with glass microballoon in the described pressure-sensitive adhesive layer.
A kind of PET reflective membrane described in the utility model, described reflector layer is an aluminium coated.
A kind of PET reflective membrane described in the utility model, described protective layer is the butyral protective layer.
The beneficial effect of the utility model PET reflective membrane is:
The utility model PET reflective membrane adopts the three-layer co-extruded film of PET as base material, and corrosion resistance and good adheres to bead by pressure-sensitive adhesive layer; adhesion property is good, is difficult for peeling off, and butyral protective layer weatherability is strong; the layers of material acting in conjunction prolongs the service life of PET reflective membrane greatly.
(4) description of drawings
Fig. 1 is the section structure schematic diagram of the utility model PET reflective membrane.
Among the figure:
PET surface layer 1, PET intermediate layer 2, PET bottom 3, reflector layer 4, pressure-sensitive adhesive layer 5, protective layer 6, glass microballoon 5.1.
(5) specific embodiment
Referring to Fig. 1, a kind of PET reflective membrane that the utility model relates to, it comprises PET surface layer 1, PET intermediate layer 2, PET bottom 3, reflector layer 4, pressure-sensitive adhesive layer 5 and the protective layer 6 that sets gradually, and is densely covered with glass microballoon 5.1 in the described pressure-sensitive adhesive layer 5.
During making, earlier with described PET surface layer 1, PET intermediate layer 2 and the PET bottom 3 three-layer co-extruded films of making;
Aluminize on PET bottom 3 surfaces then, form reflector layer 4, on reflector layer 4, apply pressure-sensitive adhesive layer 5 again, then glass microballoon 5.1 is adhered to wherein, spray one deck butyral protective layer 6 at last again.
For saving cost, can add the PET feed back in the PET intermediate layer 2.
Claims (3)
1. PET reflective membrane; it comprises PET surface layer (1), PET intermediate layer (2) and the PET bottom (3) that sets gradually; it is characterized in that: described PET bottom (3) surface is disposed with reflector layer (4), pressure-sensitive adhesive layer (5) and protective layer (6), is densely covered with glass microballoon (5.1) in the described pressure-sensitive adhesive layer (5).
2. a kind of PET reflective membrane according to claim 1 is characterized in that: described reflector layer (4) is an aluminium coated.
