Abstract

The invention relates to cooking-type ester-soluble plastic gravure compound printing ink. The cooking-type ester-soluble plastic gravure compound printing ink is prepared from, by weight, 25%-50% of n-propyl acetate, 25%-35% of polyurethane resin, 1%-5% of vinyl chloride-vinyl acetate resin, 0.1%-1% of dispersing agent, 0.5%-1% of OK412, 8%-35% of pigment and filler and 8%-20% of solvents, wherein the solvents are isopropyl alcohol and butyl acetate, the polyurethane resin is polyurethane resin of which the cooking temperature is lower than 121 DEG C, the dispersing agent is a Lubrizol 24000 dispersing agent, and OK412 is Degussa gas-phase method silicon dioxide extinction powder. The cooking-type ester-soluble plastic gravure compound printing ink has the advantages that no poisonous and harmful solvent is contained, the adhesion of the printing ink is improved, the dispersity is improved, and storage is convenient.

Description

technical field [0001] The invention belongs to the technical field of plastic gravure composite ink, and in particular relates to a cooking type ester-soluble plastic gravure composite ink. Background technique [0002] Traditional plastic composite inks use toluene and xylene as the main solvent, and ethyl ester, methyl ethyl ketone, and isopropanol as auxiliary solvents or co-solvents. The advantages of this ink are low price, fast volatilization speed, good printing adaptability, excellent adhesion fastness, good composite performance, etc., and are favored by the color printing industry; the disadvantage is that the residual solvent is large, especially the benzene content exceeds the standard, so it cannot be used for cooking. use. For the sake of environmental protection and safety, the United States and many European countries have established strict environmental protection and hygiene standards for inks, adhesives and even film materials used in the field of food ...
