The water-based silicone-acrylic film-forming emulsion is the key point, and an organic silicon monomer is introduced during the synthesis of the emulsion, so that the anti-adhesion performance of the emulsion is improved on the premise of ensuring the anti-skid performance of the emulsion, the anti-skid, temperature-resistant and wear-resistant performances of gloss oil can also be ensured when the emulsion is used for preprinting gloss oil, and the adhesion remover is fixed in a gloss oil film layer so that the gloss oil and sugar in beer are not adhered. The water-based styrene-acrylic non-film-forming emulsion mainly has the effect of improving the hardness and gloss of the gloss oil. The introduction of the modified resin improves the softening point of the gloss oil and improves the temperature resistance and the anti-adhesion performance of the gloss oil.

The common gloss oil is difficult to have both anti-skid and wear-resistant performances, and the invention ensures that the gloss oil also has the beer adhesion resistance while having both anti-skid and wear-resistant performances. The problem that beer makes carton, label adhesion among the prior art is solved.
