Abstract

Relating to the paint field, the invention discloses a novel anti-acid paint. According to a technical scheme adopted by the invention, the novel anti-acid paint comprises the following raw materials: organic resin, talcum powder, dibutyl phthalate, a silane coupling agent, organic bentonite, graphite powder, nano-aluminum powder, nano-calcium oxide, zinc oxide, butyl acetate, isopropanol and polystyrene. The paint has good adhesion, overcomes the easy shedding, cracking and other phenomena in the use process of conventional paint, and is especially suitable for the chemical industry.

Description

technical field [0001] The invention relates to the field of coatings, in particular to an acid-resistant coating. Background technique [0002] In the chemical industry, strong acids such as sulfuric acid, hydrochloric acid, and hydrofluoric acid are often used. Therefore, a layer of paint is usually applied to chemical pipelines or chemical reactors to ensure the safe operation of equipment and prolong the service life of equipment. Although the existing coatings have a certain acid resistance, with the prolongation of the service time, the coatings will crack and fall off, which will cause corrosion of equipment and bring safety hazards to production. Contents of the invention [0003] Aiming at the above problems, the present invention provides a new type of acid-resistant coating. While maintaining its acid resistance, the coating has strong adhesion, is not prone to cracks and peeling off, and prolongs its service life. [0004] In order to solve the above problems,...
