Abstract

The invention discloses an inner wall coating for a flue gas desulfurization pump and a preparation method thereof and relates to the technical field of coating production. The inner wall coating for the flue gas desulfurization pump is made of the following materials of, by mass, 80-90 parts of novolac epoxy resin, 20-25 parts of fluorocarbon resin, 12-15 parts of nano ceramic powder, 10-13 parts of zeolite powder, 8-12 parts of glass flakes, 6-10 parts of hydrogenated castor oil, 5-8 parts of carboxymethyl chitosan, 4-6 parts of copper oxide powder, 2-3 parts of oxidized polyethylene wax, 8-10 parts of Chinese wood oil, 50-60 parts of ethyl alcohol and 100-200 parts of water. According to the inner wall coating for the flue gas desulfurization pump and the preparation method thereof, the nano ceramic powder is adopted to perform modification on the novolac epoxy resin, and therefore the comprehensive application performance of the coating is improved; the use method is simple, a layer of hard and compact coating can be formed by spraying once, the adhesive force of the coating is good, the corrosion resistance and the abrasive resistance of the coating are strong, and therefore the service life is prolonged.

Description

Technical field: [0001] The invention relates to the technical field of paint production, in particular to an inner wall paint for a flue gas desulfurization pump and a preparation method thereof. Background technique: [0002] my country is a coal-fired country and the world's largest emitter of sulfur dioxide. The concentration of sulfur dioxide in more than 62% of the cities exceeds the second-level national environmental quality standard, and about 40% of the country's area is polluted by acid rain. Therefore, it is imperative to control sulfur dioxide pollution. Flue gas desulfurization treatment is generally carried out by wet method, and there is a problem of sewage treatment in this process. In order to prevent secondary pollution and save water, the detergent must be recycled, so it is necessary to select a sewage pump with strong corrosion resistance and wear resistance as a circulating water pump. Invention content: [0003] The technical problem to be solved ...
