Environment-friendly printing ink

Abstract

The invention discloses environment-friendly printing ink which is prepared from the following raw materials in parts by weight: 15-25 parts of polyamide resin, 5-15 parts of acrylic resin, 20-50 parts of a solvent, 5-10 parts of pigment, 2-4 parts of a cationic photo-initiator, 0-1 part of vinyl chloride-vinyl acetate resin, 2-4 parts of an ink enhancer, 1.5-3 parts of polyolefin wax, 1-5 parts of an abrasion-resistant auxiliary, 1-3 parts of a defoaming agent, 0.5-1.5 parts of a dispersing agent and 5-10 parts of a diluent. According to the environment-friendly printing ink provided by the invention, the used materials are benzene-free materials, so that the printing ink does not contain volatile harmful matters, is good in printing effect, high in adhesion fastness, non-inflammable, unexplosive and nontoxic, does not damage the health of printing workers, and is free of pollution to the atmosphere and good in environment friendliness; the abrasion-resistant auxiliary is added, so that the printed ink layer has a relatively small friction coefficient, and the abrasion resistance of the ink is greatly improved; the cost is relatively low, the ink layer firmly adheres, namely, the adhesive force is high, the ink layer is rub resistant, scratch resistant, high in glossiness, good in abrasion resistance and high in drying speed, and the product quality is good.

Description

Technical field [0001] The invention relates to the field of printing technology, in particular to an environmentally friendly printing ink. Background technique [0002] With the steady development of my country's offset printing market, offset printing inks have also developed rapidly, and their quality level is basically close to or has reached the international advanced level. According to incomplete statistics, the proportion of offset printing inks in my country's ink market has risen to 50% to 60%, still occupying a dominant position, and this proportion will not change much for a long time in the future. In recent years, with the development of the economy, the voice of environmental protection has become higher and higher. The printing industry has put forward new requirements for the non-toxic and pollution-free offset printing inks. The environmental protection offset printing inks have received extensive attention from users and have begun to be used in packaging, new...
