Abstract

The invention provides anticorrosive coating which is composed of the following components, by mass, 40-45 parts of epoxy acrylic resin, 3-6 parts of benzoic acid dibutyl phthalate, 5-8 parts of hydroxyethyl acrylate, 2-3 parts of polytetrafluoroethene, 12-15 parts of polyvinyl alcohol and 2-3 parts of p-methoxyphenol. The anticorrosive coating has good adhesive force (first level) and good anticorrosive performance and can be completely dried within 24 hours, and metal can be effectively prevented from being corroded after the surface of the metal is coated by the anticorrosive coating.

Description

technical field [0001] The invention belongs to the technical field of coatings, and in particular relates to an anti-corrosion coating and a preparation method thereof. Background technique [0002] Every year in China, a large amount of metals are damaged due to metal corrosion and lose their original properties. Caused a large amount of metal scrapping, economic loss is very big. People have studied various measures to prevent and inhibit the corrosion of metals, among which coating anti-rust is an effective method. Therefore, the present invention develops an anticorrosion coating for metal exterior surfaces with good adhesion and excellent corrosion resistance. Contents of the invention [0003] The invention provides an anti-corrosion coating on the outer surface of metal with good adhesion and excellent corrosion resistance. Therefore, the invention also provides a preparation method of the anti-corrosion coating. [0004] An anti-corrosion coating provided b...
