Abstract

The invention discloses a corrosion-resistant and wear-resistant coating for a mortar pump, and belongs to the field of chemical industry. Specifically, the corrosion-resistant and wear-resistant coating is prepared from the following substances: modified epoxy resin, a modified filler, a modified curing agent, polyoxyethylene polyoxypropylene ether, polyoxypropylene glycerol ether, triethyl-hexyl phosphoric acid, fatty acid polyethylene glycol ester, N-acetylimidazole, tri-(dimethylaminomethyl)phenol, ethylenediamine tetraacetic acid disodium, isopentyldiol, and propylene glycol monomethyl ether. The prepared coating has a high adhesive force to a metal pump body, is uniform in film forming, compact in structure, small in structure pore, and good in corrosion resistance, has good hardness, impact resistance and comprehensive performance, and can effectively improve service quality and prolong the service life of the mortar pump.

Description

technical field [0001] The invention belongs to the field of chemical industry, and in particular relates to a corrosion-resistant and wear-resistant coating for mortar pumps. Background technique [0002] A pump is a mechanical device used to transport liquid and increase its pressure, and it is designed to have different performances according to the different media it transports. Conventional pumps are used to transport water and other corrosive and low-impact media. However, in chemical production, in order to improve work efficiency, they are sometimes used to transport complex mixtures such as mortar. At this time, the pump is required to have good corrosion resistance. Durability, wear resistance, impact resistance. At present, the methods to improve the comprehensive performance of the pump include surface treatment of the pump body, filling of the isolation sleeve, coating of paint, etc. Among them, the coating of paint is relatively simple and common, that is, a l...
