Coating capable of preventing oxidative discoloration

Abstract

The invention discloses a coating capable of preventing oxidative discoloration. The coating capable of preventing oxidative discoloration is prepared by using the following raw materials in parts by weight: 200 to 400 parts of water, 150 to 300 parts of magnetized calcium, 100 to 500 parts of rubber powder, 100 to 200 parts of triethanolamine, 200 to 400 parts of thickening agent and 170 to 250 parts of zinc sulfide. The coating capable of preventing oxidative discoloration is nontoxic, odorless, nonflammable, explosion-proof and pollution-free; the coating is hard and wear-resistant, the water, weather and oil resistance is high, and the capacity of resisting various solvents is very strong; the electrostatic conducting performance and long-term cathode protection are stable; the high temperature and radiation resistance is high and the weldability is good; organic solvent is not contained, the chemical corrosion resistance is high and the strong acid and alkali resistance is high; the curing speed at room temperature is fast, the coating can be sprayed, brushed, poured and smeared, and the construction is convenient to perform; the coating can be complementarily applied after a coating layer is damaged, and the service life reaches 15 years.

Description

technical field [0001] The invention discloses an anti-oxidation and discoloration coating, which relates to the technical field of anti-corrosion coatings. Background technique [0002] High temperature resistant coatings can be divided into two categories: organic high temperature resistant type and inorganic high temperature resistant type. Phosphate lead powder coating is an inorganic high temperature resistant coating. It has the characteristics of heat resistance, anti-smear, and conductivity, and the raw materials are cheap and easy to obtain, and the preparation process is extremely simple. This paint is often used to paint the plates of high-voltage electrostatic precipitators, which can prolong the service life of the electrostatic precipitator and improve the operating conditions. However, the anti-corrosion ability of this high-temperature-resistant material is not outstanding, and its anti-corrosion components are easy to lose their ability at high temperature...
