Problems solved by technology

Although adding a certain amount of glass glaze enhances the cohesion between the powders and improves the wear resistance of the coating, the coating prepared by spraying cannot completely discharge the air, and there are a large number of pores, which cannot be achieved even after high temperature sintering. To improve, glass glaze needs to be painted many times, the construction is complicated, and chromium is toxic to the human body, so it is not suitable to use in large quantities

Abstract

The invention discloses an electrostatic attraction resistant coating material, which is prepared from the following raw materials (by weight): 13-15 parts of glass glaze, 67-80 parts of silicon nitride ceramic powder, 3-3.5 parts of zirconium carbide, 2-2.5 parts of tantalum nitride, 4-5 parts of chromium boride, 1.2-1.4 parts of indium-doped tin oxide, 0.4-0.5 part of zinc oxide, 0.8-1.2 parts of titanium dioxide, 0.3-0.4 part of a silane coupling agent kh560, 2-3 parts of sodium alginate, 0.3-0.4 part of sodium hexametaphosphate, 1-2 parts of white latex powder, 3.6-4 parts of polythiophene, 9-12 parts of an acrylic emulsion, 40-46 parts of isopropanol and a proper amount of anhydrous ethanol. By addition of processed glass glaze, structural defects of the coating are effectively improved, and binding ability of the coating and a matrix is raised. The prepared coating has compact surface and good continuity. A ceramic coating material with excellent comprehensive performance, good electrostatic attraction resistance and strong practicability is formed.

Description

technical field [0001] The invention relates to the technical field of ceramic coatings, in particular to an anti-static attraction coating material. Background technique [0002] Exhaust equipment plays an important role in kitchens, laboratories, factories and other fields. Generally, it can be divided into exhaust hood, air duct, dust removal and purification equipment, fan, equipment shell and other parts. Among them, the materials of dust removal and purification equipment are different according to different fields. Most of them will use alloy materials. The performance of alloy materials greatly affects the use effect and life of equipment. The thermal stress generated by the ceramic coating during the friction process is relatively small, and the coating is not prone to severe fracture. It has the characteristics of low porosity, low friction coefficient, high thermal conductivity, corrosion resistance, and high hardness. It is suitable for high temperature, corrosi...
