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.
