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.
