High-emissivity ceramic paint

Abstract

The invention discloses high-emissivity ceramic paint. The high-emissivity ceramic paint is characterized by comprising the following substances in parts by weight: 31-56 parts of copper chromite black, 3.8-4.4 parts of dispersing agent, 11.7-15 parts of silica sol, 3.4-5.9 parts of rear earth cerium oxide powder, 1-5 parts of silica sol, 25-30 parts of talcum powder, 1-3 parts of zinc borate, 3.5-14.7 parts of sodium silicate, 5-12.7 parts of polyethylene methyl ether methacrylate, 3-8 parts of tri-isotripolyisocyanate, 11-18 parts of sulfonated melamine formaldehyde condensation compound, 0-15 parts of sodium ethyl siliconate, 15.4-30.7 parts of aluminum oxide, 5.1-10.7 parts of defoaming agent, 1-14 parts of silicon carbide, 1.5-13 parts of water-soluble resin emulsion and 40.5-60 parts of water. The high-emissivity ceramic pain has the beneficial effects of high temperature resistance, high emissivity, fouling and slagging resistance, high temperature corrosion resistance, wear resistance, no dropping and bulging phenomena, capacity of being applied to carbon steel, and long service life.

Description

technical field [0001] The invention relates to a high emissivity ceramic paint. Background technique [0002] The existing ceramic coatings have low emissivity, poor wear resistance and high temperature resistance, and cannot better meet the needs of various petroleum and petrochemical heating furnaces and various boiler furnace tubes, furnace linings, and industrial kiln road furnace linings. Design requirements for related components on products such as electric heating devices, radiant heating tubes, etc. Contents of the invention [0003] The technical problem to be solved by the present invention is to provide a high emissivity ceramic coating. [0004] In order to solve the problems of the technologies described above, the technical solution adopted in the present invention is: [0005] A high-emissivity ceramic coating, characterized in that it includes the following parts by weight: 31-56 parts of copper chrome black, 3.8-4.4 parts of dispersant, 11.7-15 parts o...
