Abstract
The invention provides a ceramic coating which is prepared from the following raw materials in parts by weight: 70 to 100 parts of ceramic micro powder, 25 to 35 parts of epoxy resin, 60 to 70 parts of asbestos fiber, 20 to 30 parts of submicron ceramic powder, 18 to 26 parts of sodium phosphate, 18 to 26 parts of silicon dioxide, 15 to 20 parts of alkyl cellulose, 7 to 13 parts of titanium dioxide, 8 to 16 parts of titanium nitride, 10 to 17 parts of hydroxymethyl cellulose, 11 to 19 parts of polysiloxane, 6 to 10 parts of calcium oxide, 4 to 8 parts of silicon dioxide and 30 to 50 parts of water. The ceramic coating has high-temperature oxidation resistance and thermal shock resistance; a coating film of the ceramic coating is compact and strict, cannot be cracked or swollen and has goodacid resistance and alkali resistance; the ceramic coating is environmental-friendly and safe.
Description
technical field [0001] The invention relates to the field of coatings, in particular to a ceramic coating. Background technique [0002] Ceramics are attractive candidates for such coatings, however, pure ceramics cannot be widely used in coatings due to the poor mechanical bonding generally observed when ceramics are applied to surfaces. The temperature resistance of existing paints is not ideal, and the on-site operation and preparation are cumbersome and expensive. Although carbides and borides are also known which generally remain stable at higher temperatures, there is a limit to the extent to which these compounds soften during pretreatment. When thermal spraying is used, the metal matrix must first be added to the ceramic prior to application, and the ceramic is deposited as a second phase in the composite. Although coating deposition can basically be achieved, the use at high temperatures is also limited and cannot meet people's needs well. Contents of the invent...
