Abstract

The invention discloses a coating of the inner wall of a metal container for containing a white wine. The coating is composed of a component A and a component B according to a component A/component B weight ratio of 3-5:1, wherein the component A is composed of the following raw materials, by weight, 60-70 parts of an E-20 epoxy resin, 20-25 parts of dimethylbenzene, 5-8 parts of ethyl acetate, 8-10 parts of aluminum triphosphate, 4-6 parts of a modified composite filler, 4-5 parts of ammonia water, 3-5 parts of aluminum hydroxide, 3-5 parts of nanometer zinc oxide, 1-2 parts of polydimethylsiloxane, 1-2 parts of plant ash, 2-4 parts of polybutylacrylate, 1-2 parts of diethylamine, 1-2 parts of 2,6-di-tert-butyl-p-cresol, 1-2 parts of sodium tripolyphosphate, 0.8-1 part of an antioxidant DLTP, 0.8-1 part of N-2-(aminoethyl)-3-aminopropyltrimethoxysilane, and 0.6-1 part of polyethylene glycol. The film of the coating has excellent adhesion, high cross-linking degree, good hardness and good alcohol resistance; and the addition of the modified composite filler further enhances the mechanical and physical performances and the stability of the coating film.

Description

technical field [0001] The invention mainly relates to an inner wall coating, in particular to an inner wall coating of a metal container for containing liquor. Background technique [0002] Traditionally produced coatings for the inner walls of metal containers used to hold liquor are not stable in paint film performance, resulting in poor hardness and corrosion resistance of the coating, and some even have undesirable phenomena such as rust spots. Contents of the invention [0003] The object of the present invention is to provide a kind of coating for the inner wall of a metal container for containing white wine in order to remedy the defects of the prior art. [0004] The present invention is achieved through the following technical solutions: [0005] A coating for the inner wall of a metal container for containing liquor, which is composed of two components, A and B, in a weight ratio of 3-5:1, wherein the component A is composed of the following raw materials in ...
