Ceramic paint

Abstract

The invention discloses a ceramic paint which is composed of following raw materials including 20-50 parts of ceramic fiber, 50-80 parts of silicon micro-powder, 60-95 parts of hollow glass microbeads, 200-250 parts of kaolin, 6-8 parts of di-(2-ethylhexyl) phthalate, 10-12 parts of glycerol, 2-3 parts of dimethylbenzene, 5-8 parts of epoxy resin, 6-9 parts of sodium hexametaphosphate, 12-15 parts of sodium hydroxide, 5-10 parts of trisodium phosphate, 3-10 parts of sodium carboxymethylcellulose, 2-5 parts of hydroxyethyl cellulose, 5-10 parts of hydroxypropyl methyl cellulose, 3-10 parts of titanium carbide, 5-10 parts of titanium dioxide, 3-5 parts of zirconium nitride, 6-10 parts of titanium hydride, 5-8 parts of sodium carbonate, 8-15 parts of calcium carbonate, 12-15 parts of silicone oil, 12-15 parts of polydimethylsiloxane, 10-15 parts of carbon black, 15-20 parts of paraffin, 12-15 parts of graphene, 5-10 parts of magnesium nitride, 5-10 parts of magnesium oxide, 3-6 parts of silicon oxide, 3-8 parts of nano silicon dioxide and 300-350 parts of pure water. In the ceramic paint, the raw materials are reasonably blended. The paint has a high-temperature anti-oxidation property and a thermal shock resistant property when being sprayed on or brushed on a lining layer.

Description

technical field [0001] The invention relates to the technical field of ceramic coatings, in particular to a ceramic coating with high temperature oxidation resistance and thermal shock resistance. Background technique [0002] Protective surface coatings typically have properties that include extremely high hardness and wear-resistant properties. Ceramics are attractive candidates for such coatings. Unfortunately, pure ceramics cannot be widely used in coatings due to the poor mechanical bonding generally observed when ceramics are applied to surfaces. The existing coatings have a maximum temperature resistance of only 1200°C, and the on-site preparation is cumbersome and expensive. [0003] 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. Examples of such carbides and borides include silicon carbide, chromium carbide, boron carbide, titani...
