[0049] Example 1
[0050] A preparation method of a fireproof coating with photocatalytic properties includes the following steps:
[0051] (1) Add 45ml of water to 4.5g BYK180 polymer dispersant and stir for 7min in a stirring plate with a rotating speed of 1500 rpm; then add 10ml of aluminum dihydrogen phosphate and 10g of specific surface area of 681m. 2 / Kg ultrafine slag powder, stir for 7min; then add 4g Cu-Ce / TiO 2 , And then stir for 7 min;
[0052] (2) Reduce the speed of the stirring plate to 1000 revolutions / min, add 1g of ammonium polyphosphate, 1g of pentaerythritol and 2g of melamine, and stir for 35min to prepare a fireproof white slurry;
[0053] (3) Add the fireproof white slurry prepared in step (2) to the paint mixing tank, adjust the rotation speed of the stirring plate to 500 rpm, and then add 0.15g lead oxide, 0.25g zinc powder, 1ml nano mother liquor, and stir for 25min. The final target product has a fireproof coating with photocatalytic properties.
