Problems solved by technology

Since water-based varnish uses water as a solvent, it will not have a swelling effect on the ink on the surface of the printed matter, so it generally has the defect of poor adhesion to the surface of the printed matter, and the film formed by the water-based varnish is still wear-resistant. The problem of poor performance and difficult drying has become a technical bottleneck hindering the further development of water-based varnishes

Abstract

The invention belongs to the technical field of coatings and discloses high-gloss and friction-resistant varnish and a preparation method thereof. The varnish is prepared from raw materials as follows: tung oil, linseed oil, cera alba, rosin modified phenolic resin, mineral oil, gel, a drying agent and an antioxidant. The varnish has the characteristics of good friction resistance, high gloss and proneness to drying, and the preparation process of the varnish has the advantages of being convenient to operate, low in cost and suitable for large-scale industrial production.

Description

technical field [0001] The invention belongs to the technical field of coatings, and in particular relates to a high-gloss, friction-resistant varnish and a preparation method thereof. Background technique [0002] Varnish is also called varnish or wear-resistant varnish. By coating it on the outer layer of ink, it can form a thin and uniform transparent bright layer on the surface of printed matter after leveling, drying, calendering and curing. , so that the gloss of the printed product can be increased, the visual beauty can be increased, and the printed product can be protected at the same time. To a certain extent, its wear resistance, chemical resistance, water resistance and corrosion resistance can be improved, so that the varnish Widely used in printing, packaging and other industries. [0003] At present, with people's emphasis on environmental protection, the research on water-based varnishes has been developed by leaps and bounds. For example, Chinese patent do...
