Abstract

The invention relates to a coating composition which comprises the following components: hydroxylated fiber resin, methyl hydroxy crylic acid oligomer, polyethersulfone resin, silicone acrylic emulsion, alcohol acid emulsion, ethylene glycol dimethyl ester, 2-ethylhexyl acrylate, nano powder, inorganic bentonite, aluminum triphosphate, titanium oxide, clay, sodium hexametaphosphate, m-nitrophenol, lauryl mercaptan, glycerol, an auxiliary and acetone. The coating composition has the following beneficial effects of good adhesive force, good glossiness, certain flexibility, small possibility of falling, low cost, less residual monomers and no secondary pollution to packaging materials.

Description

technical field [0001] The invention relates to a coating composition and relates to the technical field of packaging coatings. Background technique [0002] Food packaging coatings are the most important type of coatings. At present, the requirements for packaging coatings require that they have good adhesion, good gloss, certain flexibility, not easy to fall off, and low cost. Common coatings generally only have one or two of the above characteristics, and it is difficult to integrate all the characteristics. Contents of the invention [0003] The technical problem to be solved by the present invention is to provide a coating composition, which solves the problem that food packaging coatings cannot have good gloss, flexibility, adhesion and other characteristics at the same time. [0004] In order to solve the problems of the technologies described above, the technical solution adopted in the present invention is: [0005] A coating composition, characterized in that i...
