Problems solved by technology

Chemical pumps not only need to have strong corrosion resistance, but also need to have a certain strength of wear resistance when transporting some special materials. However, most of the existing coatings have poor wear resistance. When transporting special materials After a long period of time, the problem of serious wear on the surface of the coating is prone to occur. After the coating of the chemical pump is worn, the corrosion of the special material to the chemical pump body increases, the corrosion intensifies, and the service life of the chemical pump is greatly shortened.

Abstract

The invention discloses an anti-wear coating for a chemical pump. The anti-wear coating is prepared according to the following step: mixing color paste with emulsion. By modification treatment of sericite powder, the surface of the sericite powder is covered by an organic group, so that the surface group property and the surface energy of the sericite powder can be effectively changed, and the compatibility between the modified sericite powder and other components in the coating can be fundamentally improved; by adding of isosorbide, the phenomenon that the sericite powder is easy to agglomerate can be improved, and the interfacial force between the sericite powder and a base body can be enhanced; therefore, the sericite powder can be dispersed more uniformly; in a friction process, damage within a relatively large range due to stress concentration can be avoided.

Description

technical field [0001] The invention belongs to the technical field of chemical pump coatings, in particular to a wear-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 not only need to have strong corrosion resistance, but also need to have a certain strength of wear resistance when transporting some special materials. However, most of the existing coatings have poor wear resistance. When transporting special materials After a long time, the problem of serious wear on the surface of the paint is prone to occur. After the paint of the chemical pump is wo...
