Brushed high-strength abrasion-resistant anticorrosive coating and preparation method

Abstract

The invention relates to a brushed high-strength abrasion-resistant anticorrosive coating. The component A of the coating comprises 80 to 100 parts of mixed epoxy resin, 10 to 15 parts of toughening agent, 5 to 10 parts of diluent, 60 to 100 parts of ceramic powder, 5 to 10 parts of quartz powder, 20 to 30 parts of titanium white powder, 5 to 10 parts of fumed silica, 0.1 to 0.5 part of de-foaming agent, 0.1 to 0.5 part of flatting agent, and 0.1 to 0.5 part of wetting dispersant. The component B comprises 40 to 50 parts of mixed amine curing agent, 2 to 5 parts of epoxy accelerant, and 2 to 5 parts of silane coupling agent. The coating is easy to construct and easy to operate, and the coating does not contain volatile solvents and has low smell and low harm to a human body; the coating has extremely high adhesion after being cured, and can resist erosion of different media such as 40 percent sulfuric acid, 30 percent hydrochloric acid, 20 percent sodium hydroxide, 10 percent sodium chloride and engine oil and abrasion and cavitation of different mines such as drifting sand, gas dust and mud.

Description

technical field [0001] The invention belongs to the technical field of polymers, and in particular relates to a brush-coated high-strength wear-resistant and anti-corrosion coating and a preparation method. Background technique [0002] As a general mechanical equipment, pumps are widely used in various fields of the national economy. Due to the destructive effects of rust, corrosion, abrasion and cavitation, the surface of the pump casing and pump wheel becomes uneven, the friction coefficient gradually increases, the pump efficiency decreases, the power consumption increases, and the service life of the pump is shortened. At present, the requirements of pump manufacturers for the wear-resistant and anti-corrosion properties of pump casings, impellers, and guard plates are increasing day by day, and the existing processing methods of enterprises mainly use replacement materials to improve the anti-wear and anti-corrosion effects. Some customers need to do internal coating, ...

Problems solved by technology

Due to the destructive effects of rust, corrosion, abrasion and cavitation, the surface of the pump casing and pump wheel becomes uneven, the friction coefficient gradually increases, the pump efficiency decreases, the power consumption increases, and the service life of the pump is shortened.

At present, the requirements of pump manufacturers for the wear-resistant and anti-corrosion properties of pump casings, impellers, and guard plates are increasing day by day, and the existing processing methods of enterprises are mainly to replace materials to improve the anti-wear and anti-corrosion effects. Some customers need to do internal coating, but The cost is high (external processing), so some pump manufacturers urgently need a more economical and easy-to-use product to improve the wear-resistant and anti-corrosion effect of the pump
