Abstract

The invention discloses paint for a chemical pump casing. The paint is prepared from the following materials: styrene, hollow glass microbeads, polytetrafluoroethylene resin, glycerin alkyd resin, talcum powder, carboxymethylcellulose, silicon nitride, tripolycyanamide, aluminum paste modified epoxy resin and amino silane. After the paint for the chemical pump casing is formed into a film, the film has high hardness, good wear resistance, short actually drying time, good corrosion resistance, good adhesive force, low cost, chemical corrosion resistance, oil resistance and high impact resistance, has no breaking or dropping phenomenon under the action of scouring and mechanical force of high-speed airflow, sand stone and water in application and is suitable for the application environment of a chemical pump. By virtue of the synergistic effect of various components, the service life of the paint film is greatly prolonged.

Description

technical field [0001] The invention relates to the technical field of coatings for chemical pumps, in particular to a coating for pump casings of chemical pumps. Background technique [0002] Chemical pumps are mainly used to transport chemical materials, and most chemical pumps are used in harsh environments. During the process, they will be exposed to corrosive substances such as strong acids and alkalis. When chemical pumps are placed in the open environment, they will be exposed to ultraviolet rays, rain and snow and Corrosion, therefore, the pump casing of the chemical pump needs to have greater strength and corrosion resistance. The existing chemical pump casing is sprayed with paint, but the existing chemical pump paint has poor corrosion resistance, low service life, and low adhesion, which cannot meet the needs of some harsh environments in the market. Contents of the invention [0003] The object of the present invention is to provide a kind of paint for chemic...
