▎ 摘　　要

NOVELTY - Antifouling self-cleaning coating comprises 0.1-1 wt.% hydrophobic material, 1-7.5 wt.% photocatalytic material, 10-15 wt.% water emulsion, 30-45 wt.% filling, 0.2-0.5 wt.% auxiliary agent and 35-50 wt.% water, where the photocatalytic material comprises dicyanocarbodiimide, doped dicyanocarbodiimide, composite dicyanocarbodiimide and nano-bismuth oxide. USE - The antifouling self-cleaning coating is useful in inner and outer walls, kitchens, bathrooms, basements and store rooms and purifying pollutants e.g. ozone, nitrogen oxides and volatile organic compounds. ADVANTAGE - The coating: is environmentally friendly; has excellent hydrophobic antifouling, purifying self-cleaning and air purifying performance. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is also included for preparing the antifouling self-cleaning coating comprising taking filler, hydrophobic material and photocatalytic material, mixing in a mixing tank and stirring at a low speed, slowly adding water, keep stirring and increasing the stirring speed to ensure that the powder is fully soaked, slowly adding the emulsion and continuously stirring to further improve the stirring speed, slowly adding the auxiliary agent, adjusting the stirring speed and adjusting the consistency of the coating.
