Problems solved by technology

At present, there are many release papers on the market, most of which are made by coating heat-curing release emulsion or self-drying release agent on the paper products. The drying speed is slow, which seriously affects the production efficiency.
In addition, although there are some UV paper varnishes added with additives that can improve slipperiness on the market, these additives have poor performance in reducing surface tension, low smoothness, and no peeling effect. Coated film surface, no release effect when pulled hard

Abstract

The present invention relates to the technical field of varnish, in particular to a UV paper varnish with a release effect and super smoothness after UV curing, and a preparation method thereof. The UV paper varnish of the present invention consists of 15-30 parts of epoxy resin Acrylic resin, 25-40 parts of modified acrylic resin, 40-50 parts of acrylic monomer, 10-15 parts of photoinitiator, 2-6 parts of super slippery peeling aid, 1-4 parts of Auxiliary composition; the preparation method of the present invention is as follows: a, adding acrylic monomer, matting agent, super slippery peeling aid and auxiliary agent into a stirring pot for pre-dispersion, mixing and stirring evenly; b, adding to the stirring pot Add epoxy acrylic resin, modified acrylic resin, acrylic monomer and photoinitiator, mix and stir evenly to obtain oil; c, filter the oil in sequence. The UV paper varnish of the invention has the advantages of good super smoothness, high gloss, good adhesion, high wear resistance and the like.

Description

technical field [0001] The invention relates to the technical field of varnish, in particular to a UV paper varnish with release effect and super smoothness after UV curing and a preparation method thereof. Background technique [0002] Release paper, also known as release paper and anti-adhesive paper, is a kind of anti-adhesive paper that can prevent the pressure-sensitive adhesive from sticking and protect the pressure-sensitive adhesive from pollution. It is widely used in electronic products, automotive foam, packaging Industry, advertising, printing and other fields. There are many release papers on the market, most of which are made by coating heat-curing release emulsions or self-drying release agents on paper products. The drying speed is slow, which seriously affects production efficiency. In addition, although there are some UV paper varnishes added with additives that can improve slipperiness on the market, these additives have poor performance in reducing surfa...
