Problems solved by technology

Chemical pumps need to have strong corrosion resistance, especially acid and alkali corrosion resistance. However, most of the existing coatings have poor acid and alkali corrosion resistance. When transporting special materials, over time, The surface of the coating film of the chemical pump is easily damaged. After the surface of the coating film of the chemical pump is damaged, the coating film cannot continue to protect the chemical pump body. shortening of

Abstract

The invention discloses a chemical corrosion resistant coating for a chemical pump. The chemical corrosion resistant coating is prepared from the following components: 1,3-butanediol, glycerin alkyd resin, hydroxyethyl cellulose, polydimethylsiloxane, methyl acrylate, methylbenzotriazole, beta-methallyl alcohol, zinc oxide powder, modified attapulgite, ammonium polyphosphate, nano calcium carbonate and aids. According to the aids and modified attapulgite prepared by lots of experiment researches, the stability and corrosion resistance of the coating disclosed by the invention can be greatly influenced, and due to reasonable selection of the aids and the usage amount of the modified attapulgite, the performance of the coating disclosed by the invention, particularly chemical corrosion resistance, is greatly influenced.

Description

technical field [0001] The invention belongs to the technical field of chemical pump coatings, in particular to a chemical corrosion-resistant coating for chemical pumps. Background technique [0002] Chemical pumps are a general term for mechanical chemical pumps used to transport liquids and increase their pressure. They can meet the requirements of high temperature resistance, low temperature resistance, corrosion resistance, wear resistance, no leakage or less leakage, and pumps that can transport liquids in a critical state. These pumps are collectively referred to as chemical pumps. Chemical pumps need to have strong corrosion resistance, especially acid and alkali corrosion resistance is particularly important, but most of the existing coatings have poor acid and alkali corrosion resistance, when transporting special materials, over time, The surface of the coating film of the chemical pump is easily damaged. After the surface of the coating film of the chemical pump...
