Abstract

The invention discloses a paint for a housing of a magnetic drive pump. The paint comprises the following components: diethyl phthalate, hollow glass spheres, teflon resin, a lacquer tree branch extract product, silicon carbide micropowder, carboxymethyl cellulose, alumina micropowder, melamine, aluminum paste-modified epoxy resin, and amino-silane. After the paint forms a film, the film has the advantages that the hardness is high, wear resistance is good, hard drying time is short, corrosion resisting performance is good, adhesive force is good, cost is low, the dispersibility of the components is good, and the film is uniform and stable. The paint greatly increases the service life of the film through cooperation of the components.

Description

technical field [0001] The invention relates to the technical field of coatings for magnetic pumps, in particular to a coating for magnetic pump shells. Background technique [0002] The vast majority of media other than water will be transported by magnetic pumps, and most of the magnetic pumps are used in harsh environments. When the magnetic pump is placed in the open air, it will be irradiated and eroded by ultraviolet rays, rain and snow. Therefore, the magnetic pump’s The shell needs to have greater strength and corrosion resistance. The existing magnetic pump casing is sprayed with paint, but the existing magnetic 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 magnetic pump casing. [0004] The present invention is realized through the following technical soluti...
