[0025] see figure 1 , the invention provides a technical solution: a preparation method of continuous high temperature resistant paint. The preparation method includes the following steps.
[0026] In step S101, take 100 parts by mass of water and place it in the generator, and add 1.8-2.2 parts of sodium hydroxide to the generator, continue to stir and heat to 20-25°C, and stir for 25 seconds;
[0027] In step S102, 32-35 parts of titanium dioxide, 0.5 parts of bridging agent, 0.55-0.85 parts of isopropanol and 8-9 parts of polyvinyl alcohol are added to the generator, continuously stirred and heated to 90-110°C, stirring for 65-78 seconds;
[0028] In step S103, cool to 40-50°C, add 1.8-2 parts of toughening agent to the generator, and stir for 90-110 seconds;
[0029] In step S104, cool to 22-24°C, add 3.2-3.6 parts of unsaturated polyester resin to the generator, and stir for 200-350 seconds;
[0030] In step S105, add 0.70-0.80 parts of borax to the generator, and sti...
