Harden dumb light hot melt composite membrane and preparation method thereof
Technical field
The present invention relates to laminated film technical field, specifically a kind of hardening dumb light heats composite membrane.
Background technique
With in the development and production and living of polymer science technology to the light-weighted demand of product, various film products Have been widely used for the every field in social production life.Hot melt composite membrane is made by transparent substrate lamination thermoplastic resin At being a kind of colorless and transparent, glossiness film, there is good mechanical property, optical, electric property, hot property and resistance to Chemicals etc..Hot melt composite membrane is widely used in hot melt encapsulation.Plastic packaging film is exactly one of representative therein, plastic packaging film quilt It is widely used in the protection of the paper documents such as certificate, file, photo.
However plastic film is easily scratched by hard object sharp instrument in use, is influenced apparent beautiful and is used function.By in material The hardness that additional hard surface coating improves these material surfaces is implemented on material surface, so that these high molecular film materials is resistance to Scratch function improves, and application value is greatly improved.
There is dumb light composite membrane on the market now, but coating fastness is inadequate, is easily damaged in use, therefore also limits Its a large amount of application is made.
Summary of the invention
The present invention in order to solve problems in the prior art, provides a kind of hardening dumb light hot melt composite membrane and its preparation side Method, layer solution are uniformly mixed, and since coating passes through UV curing process, are enhanced the adhesion of hardening coat and substrate surface, are made Substrate surface achievees the effect that wear-resisting hardening has dumb light again.
The present invention provides a kind of hardening dumb lights to heat composite membrane, including substrate layer and is passed through by hot-melt resin particle Melting extrusion and substrate layer compound hot-melt resin layer are coated with hardening dumb light UV coating on the substrate layer, substrate layer with Adhesion promoting layer and adhesion promoting layer are added between hot-melt resin layer.
The substrate layer select polyethylene terephthalate, polypropylene, polyvinyl chloride, in polycarbonate film A kind of material is made, with a thickness of 10-200um.
The hot-melt resin select ethylene-vinyl acetate copolymer, polyethylene, ethylene-acrylic acid copolymer resin, One of polyolefin resin material is made.With a thickness of 10-200um.
The adhesion promoting layer is the viscosity solution coating of enhancing base materials layer surface tension.
The adhesion promoting layer is tackifying hot-melt resin.
The present invention also provides a kind of preparation methods of hardening dumb light hot melt composite membrane, comprising the following steps:
1) stirring solvent the preparation of dumb light coating: is added in organic polymer engrafted nanometer silica and certain proportion flatting silica Hardening dumb light solution is obtained, hardening dumb light solution is uniformly mixed to obtain dumb light coating with addition photoinitiator in flatting silica, wherein Photoinitiator selects one of benzophenone, 2- hydroxy-2-methyl -1- phenyl -1- acetone material.
2) to PET base material layer after Corona Surface Treatment, dumb light coating is uniformly coated in a manner of roller coating after mixing In one side surface of PET base material layer, solidify through UV LJV oven, forms hardening dumb light coating in PET base material layer surface cure;
3) to PET base material layer surface preparation: another surface of PET base material layer carries out at surface through corona and adhesion promoter pretreatment Reason increases adhesion promoting layer and adhesion promoting layer;
4) tackifying resin passes through extruder melting extrusion, compound with PET base material layer progress, further enhances PET and composite layer Adhesive strength;
5) hot melt EVA resin is by extruder melting extrusion, with PET base material carry out it is compound after through ozone Oxidation Treatment, obtain Hot-melt resin laminated film.
6) the hardening dumb light plastic packaging film formed is through cooling, winding molding.
The beneficial effects of the invention are that:
1, dumb light solution coating compared with prior art, is hardened in substrate using organic polymer engrafted nanometer particle in the present invention Then surface is obtained by the cured method of UV.There is the coating of matte effect, coating solution mixing simultaneously using novel hardening Uniformly, since coating passes through UV curing process, the adhesion of hardening coat and substrate surface is enhanced, substrate surface is made to reach resistance to Mill hardening has the effect of dumb light again.
2, adhesion promoting layer and adhesion promoting layer further, are added between substrate and hot melt layer, increase composite membrane between layers Adhesion strength.
