Embodiment 1-8
[0064] The coating method of ceramic non-stick coating of the present invention is specifically as follows:
[0065] a. Pre-treatment: sandblasting the metal substrate to make the surface rough to increase the adhesion of the coating;
[0066] b. Coating mixing: Mix and stir components A and B in Table 1 according to the weight ratio for 6 to 7 hours to make the reactants undergo hydrolysis and condensation reaction, then add component C and mix evenly;
[0067] c. Paint spraying: preheat the substrate treated in step a to 50-60°C, and spray the paint on the preheated substrate through compressed air;
[0068] d, sintering and solidification: level and dry the substrate obtained in step c at a temperature of 55-70°C for 10 minutes, then gradually raise the temperature to 280°C-300°C, sinter for 10 minutes and then cool.

[0070] The coating method of ceramic non-stick coating of the present invention is specifically as follows:
[0071] a. Pre-treatment: sandblasting the metal substrate to make the surface rough to increase the adhesion of the coating;
[0072] b. Coating mixing: Mix and roll the A and B components in the continued Table 1 according to the weight ratio for 8 to 9 hours, so that the reactants undergo hydrolysis and condensation reaction, and then add the C component and mix evenly;
[0073] c. Paint spraying: preheat the substrate treated in step a to 60-80°C, and spray the paint on the preheated substrate through compressed air;
[0074] d, sintering and solidification: level and dry the base material obtained in step c at 70-80°C for 10 minutes, then gradually raise the temperature to 280-300°C, sinter for 10 minutes and then cool.

Abstract
The invention belongs to the process technology field of coating liquid or other fluid on the surface, in particular to a ceramic non-stick coating with the bacteriostasis action. The coating is formed by mixing a component (A), a component (B) and a component (C) in a weight ratio of 2 to 0.5-2 to 0.1-2, wherein the component (A) is prepared by dispersing and grinding the following components in percentage by weight: 50-100 percent of silica sol, 0-50 percent of temperature-resisting pigment, 0-20 percent of inert pigment, 0-2 percent of dispersing aid and 0-2 percent of leveling aid for more than 2 h; the component (B) is prepared by mixing the following components in percentage by mass:0.2-1.5 percent of acetic acid and the balance of at least one silane; and the component (C) is prepared by dispersing and dissolving the following components in percent by mass of 1-10 percent of alcohol-soluble acrylic resin, 0-30 percent of non-stick agent and 1-50 percent of antibacterial material in 50-95 percent of isopropanol. Compared with a traditional non-stick coating, the non-stick coating without being added with substances, such as PTFE (Polytetrafluoroethylene), PFOA (Perfluorooctanoic Acid), and the like is environment-friendly and safe and has the bacteriostasis and sterilization functions.
Description
technical field [0001] The invention belongs to the technical field of surface coating liquid or other fluids, and relates to a non-stick coating, in particular to a ceramic non-stick coating with antibacterial effect. Background technique [0002] Non-stick coating has developed rapidly since it was invented and applied in 1958. It is widely used in cooking utensils, small household appliances and other fields, bringing convenience to people's life. However, the core component of the existing non-stick coating is polytetrafluoroethylene (PTFE), and PTFE will add a very small amount of perfluorooctanoic acid ammonium (PFOA) during the production process. After the chemically stable PFOA enters the natural environment and the human body, Will last for a long time instead of breaking down quickly. Studies have shown that low-dose PFOA not only appears in rivers, oceans and soil, but also exists in people's blood, and has been confirmed to have carcinogenic effects and other a...
