[0019] In the present embodiment, the preparation method of described coating comprises the following steps:
[0020] a. Grinding pyrophyllite and zinc oxide into fine powder, then uniformly mixing with nano-attapulgite, nano-kaolinite, shell powder, nano-titanium oxide, sepiolite powder and air-purifying sterilizing powder to prepare mixed powder;
[0021] b. Mix 2 / 3 volume of deionized water with polyvinyl alcohol, stir and heat up to 90°C. After the polyvinyl alcohol is completely dissolved, cool down to room temperature, add polyacrylate emulsion and epoxy resin, and heat at 300r / min Stir at least 45min at the stirring speed, then add polyacrylamide, mineral oil defoamer, polyacrylate ammonium salt dispersant, carboxymethyl cellulose, coconut oil, remaining deionized water and the mixture prepared in step a powder, and stirred at a stirring speed of 1000r / min for 10 hours; it is conducive to better dispersion of various raw materials, better compatibility, and better syner...
