Quick-dry tight metal paint surface repairing agent

Abstract

The invention discloses a quick-dry tight metal paint surface repairing agent. The quick-dry tight metal paint surface repairing agent is prepared from 20-30 parts of alkyl(meth)acrylate copolymer, 15-20 parts of polyimide, 15-20 parts of oil-soluble phenolic resin, 15-20 parts of tert-butylation phenyl phosphate, 15-20 parts of tributyl phosphate, 5-10 parts of polyacrylamide, 5-10 parts of polyaluminium chloride, 10-20 parts of surfactant and 0.02-0.4 part of stearic acid. The defects in the prior art are overcome, the metal surface repairing effect is good, no object surface is damaged, the quick-dry tight metal paint surface repairing agent is good in durability, high in lasting effect, free of toxins, harm and pollution and convenient to use, and repairing is fast.

Description

technical field

[0001] The invention relates to the technical field of metal maintenance and repair, in particular to a quick-drying firm metal paint repair agent. Background technique

[0002] With the development of industrial modernization, the requirements for the safe and continuous operation of various mechanical equipment are getting higher and higher, and the long-term operation of equipment under harsh environmental conditions such as high temperature, high pressure, impact, and corrosion often causes the entire part to be damaged due to local damage. Scrapping will eventually lead to equipment shutdown. In recent years, industrial enterprises hope to achieve various forms of metal repairs such as wear, corrosion, leakage, erosion, cavitation, and erosion through the use of metal repair agents, so as to reduce dependence on metal materials and improve Flexibility in equipment maintenance.

[0003] During the use of metal in different environments, discoloration, ye...
