Abstract

The invention relates to improved high-temperature-resistant metal anti-corrosive paint, which consists of the following components in parts by mass: 30-40 parts of GHNK high-temperature-resistant adhesive, 15-20 parts of polyaniline / graphene composite material, 15-20 parts of coloring pigment, 5-10 parts of superfine talcum powder, 5-10 parts of superfine mica powder, 5-10 parts of kaolin, 0.2-0.5 parts of SN-612 flatting agent, 0.3-0.5 parts of wetting agent X-405, 0.1-0.3 parts of dimethyl ethanolamine, 0.1-0.3 parts of anti-corrosive agent 981, 0.5-1 part of GHP 101 thickening agent, 0.1-0.3 parts of tributyl phosphate and 4-13 parts of water. The paint prepared by the invention has the advantages of excellent water-proof and anti-corrosive properties, high temperature resistance, alkaline resistance, weathering resistance, scrub resistance, artificial aging resistance and the like, passivation and corrosion inhibition of a metal base material can be realized, meanwhile, the use of heavy metals such as chromium which can cause environmental pollution is avoided, and the paint is easy to prepare, low in cost and is easy for industrial batch production.

Description

technical field [0001] The invention relates to an improved metal anticorrosion coating, in particular to an improved high temperature resistant metal anticorrosion coating. [0002] Background technique [0003] The phenomenon that metal is damaged by the chemical or electrochemical action of the surrounding environment medium is called metal corrosion. In industrial enterprises such as electric power, metallurgy, chemical industry, machinery, transportation, etc., a large number of metal equipment such as iron and steel, metal components and metal buried parts are used. Corrosion, severe corrosion or damage may even cause major accidents and huge economic losses. At present, metal corrosion has brought huge economic losses to countries all over the world. According to some corrosion loss data released by the United States, Japan, Canada and other countries, corrosion has caused a large number of direct economic losses, and it is estimated that about 20 % of metal materi...
