The utility model discloses the reflective membrane of preparation, its apparent is bright, is fit for producing the colored product, and application range is also broad.
Description
Technical Field
The utility model relates to a reflective membrane material especially relates to a hot melt adhesive layer in microprism reflective membrane.
Background
The microprism reflective membrane is a retro-reflective film taking a cubic pyramid as a reflection unit structure, has the excellent characteristics of high retro-reflective coefficient, simple manufacturing process, convenience in pasting and the like, and is widely applied to the field of traffic safety. The microprism reflective film consists of a surface layer, a microprism layer, an air layer, a hot melt adhesive layer, a back adhesive layer and a release layer.
The hot melt adhesive film is generated by coating and casting, or is coated, cast and compounded on the surface of the PET polyester film to form a hot melt adhesive PET film, and the PET is peeled to form the hot melt adhesive film, or the PET and the hot melt adhesive are integrated to form a hot melt adhesive PET composite film. And the hot melt adhesive film is bonded with the micro prism layer through an embossing process. When embossing, the embossing roller carved with a certain pattern is heated, the raised edges on the surface of the embossing roller exert pressure on the PET surface, the hot melt adhesive is melted and adhered to the surface of the microprism to form a sealed air capsule layer, so that the surface of the microprism, which is not adhered with the hot melt adhesive, is contacted with air, and the retroreflection function is ensured.
Two methods are used for generating the micro prism layer, one method is a hot pressing mode, namely a resin film and a micro prism mold are pressed and demoulded in a high-temperature and high-pressure mode, and the micro prism layer is formed on the surface of the resin film; the other method is a photocuring method, namely coating UV photocuring resin on the surface of the resin film, then adhering the resin film to a microprism mold, photocuring, demolding and forming a microprism layer on the surface of the resin film. The resin film material is generally one or a combination of PMMA, PC, PVC and the like.
When the micro prism layer generated by UV light curing is subsequently embossed, due to non-hot-melt property, the micro prism layer can not be firmly adhered to a hot melt adhesive film or a hot melt adhesive PET composite film when being embossed, so that at present, common manufacturers do not adopt an embossing process, but vacuum aluminize the surface of the micro prism layer and then compound the micro prism layer with a back adhesive layer on a release layer. The reflective film produced by the process has dark appearance, cannot meet the color requirement, cannot produce colored products and has narrow application range.
Disclosure of Invention
The utility model aims at solving the above problems existing in the prior art and providing a composite hot melt adhesive film for embossing microprism reflective films. The utility model discloses the reflective membrane of preparation, its apparent is bright, is fit for producing the colored product, and application range is also broad.
The utility model discloses the purpose realizes like this: the utility model provides a UV photocuring microprism reflective membrane composite hot melt adhesive membrane for knurling, it includes the PET membrane, the one side coating of PET membrane and microprism laminating has the one deck adhesive, compounds the hot melt adhesive film on the adhesive.
The composite hot melt adhesive film for embossing the UV light-cured microprism reflective film is characterized in that the thickness of the PET film is 12-50 mu m, the thickness of the adhesive layer is 15-45 mu m, and the thickness of the hot melt adhesive film is 20-60 mu m.
The composite hot melt adhesive film for embossing the UV light-cured microprism reflective film comprises the following resins in percentage by weight: acrylate resin, polyester resin, polyurethane resin, vinyl chloride-vinyl acetate resin, polyamide resin, epichlorohydrin resin, isocyanate resin and the like or a combination of a plurality of the above resins.
The composite hot melt adhesive film for embossing the UV light-cured microprism reflective film is prepared by combining one or more of resin acrylate resin, polyester resin, polyurethane resin, isocyanate resin, SBS rubber and the like of an adhesive.
The utility model discloses when the knurling, arris on the embossing roller to compound hot melt adhesive membrane's PET face, applys certain temperature and pressure, and the hot melt adhesive melts, and the hot melt adhesive is oozed into to the underlying pressure sensitive adhesive, has increased the cohesiveness of hot melt adhesive to with the firm bonding in microprism surface, form sealed air pocket. The non-adhesive part is a hot-melt adhesive layer below the air bag, so that the air bag is non-adhesive at normal temperature, the permeation of the pressure-sensitive adhesive is isolated, the adhesion of the soft pressure-sensitive adhesive to the surface of the microprism at room temperature is avoided, the air below the microprism is ensured, and the retroreflection performance of the microprism is ensured.
The composite hot melt adhesive film solves the problem of infirm embossing sealing of the UV photocuring micro prism layer, can produce products with different colors, and has good market prospect.
