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 utility model additionally provides a kind of preparation method of hardening dumb light hot melt composite membrane, comprising the following steps:
1) 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 stirred to get, 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 table through corona and adhesion promoter pretreatment
Surface treatment 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 answers
Close the adhesive strength of layer；
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 utility model beneficial effect is:
1, it compared with prior art, is applied in the utility model using organic polymer engrafted nanometer particle hardening dumb light solution
Then cloth is obtained in substrate surface by the cured method of UV.There is the coating of matte effect, coating simultaneously using novel hardening
Solution is uniformly mixed, and since coating passes through UV curing process, is enhanced the adhesion of hardening coat and substrate surface, is made substrate table
Face achievees the effect that wear-resisting hardening has 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.
