Ceramic coating

The invention relates to a ceramic coating. The ceramic coating is prepared from the following components: silicone acrylic emulsion, ceramic powder, tall oil, N-fluorine-N '-(chloromethyl) triethylene diamine bis (tetrafluoroborate), silver nitrate and polyamide-imide. The silicone acrylic emulsion is adopted to assist the dispersion of the ceramic powder; the tall oil has an adhesive property, main components of the tall oil are fatty acid and abietic acid, silver nitrate is used as a catalyst and can react with N-fluorine-N '-(chloromethyl) triethylenediamine bis (tetrafluoroborate) to introduce fluorine functional groups, the surface energy of the coating is reduced along with substitution of fluorine atoms, the wettability can be improved due to reduction of the surface energy, the coating is easier to spread uniformly, and the coating has a good anti-corrosion effect. The affinity is improved, so that the bonding strength of the coating is improved under the synergistic effect of the bonding force of ta
