Anticorrosion and antirust coating

Abstract

The invention belongs to the field of coatings and particularly relates to an anticorrosion and antirust coating. The anticorrosion and antirust coating is prepared from the following raw materials in parts by weight: 20-25 parts of ultrafine polyimide resin powder, 10-15 parts of phenolic resin, 9-13 parts of pigment, 2-4 parts of calcium chloride, 2-6 parts of rosin, 10-20 parts of cyclohexanone, 5-10 parts of ethyl acetate and 4-7 parts of methyl benzoate. The anticorrosion and antirust coating has anticorrosion, antirust, anti-condensation and anti-icing effects, has good abrasive resistance and excellent mechanical performance, can also prevent high temperature and has good adhesive force, high durability and very ideal endurance and acid and alkali resistance. The anticorrosion and antirust coating is mainly applied to ocean and offshore vessels, ship submarines, ocean engineering, drilling platforms, ports and wharfs, water conservancy facilities, petrochemical equipment, bridge buildings and other metal and concrete facilities.

Description

technical field [0001] The invention belongs to the field of coatings, in particular to an anti-corrosion and anti-rust coating. Background technique [0002] Metal corrosion is a very common phenomenon in nature, which is very harmful to the metal components used in people's daily life and production, especially those metal components in harsh environments, such as bridges, vehicles, Ships, steel structures, chemicals, medicine, electroplating workshops and other structures, upper and lower water pipes, drainage pipes, seawater pipes, etc., are more severely corroded than metal components under normal conditions. In some cases, the annual corrosion depth of metal components It can reach 1-2 mm, and even the corrosion degree of some local parts can reach more than 3 mm per year. This is a very serious problem, so metal anti-corrosion is a problem that people have to solve all the time. [0003] At present, people use anti-corrosion coatings to realize the anti-corrosion pro...

AI Technical Summary

Problems solved by technology

The main material epoxy resin used in the coating formula of the invention has high brittleness after curing, which shortens the life of the coating, and the anti-corrosion and anti-rust effect of the coating is not good enough
