To improve the antifouling and wear-resistance of cement-based inorganicartificial stone protective coating，inorganic artificial stone anti-fouling coating was preparedusing organic silicone resin as the film-forming material and fumed silica as filler. The impactof fumed silica on the anti-fouling and wear-resistance of the coating was evaluated throughpollution of typical contaminated fluid，water contact angle，wear-resistance test and scanningelectron microscopy. The results indicated that the addition of fumed silica could effectivelyimprove the hardness and wear-resistance of the coating. However，due to its irregular surface morphology and the presence of a large number of hydroxyl groups，the surface wettability wasenhanced and the anti-fouling performance decreased at high doping level. When 3% fumed silica was added，the coating showed the best comprehensive performance，the color difference ΔE<1. 5 for methyl violet and vinegar was obtained，and a good appearance and good anti-fouling performance maintained after 4 000 times of heavy friction. This coating can be widelyused in inorganic artificial stones and other cement-based decorative materials to solve thefouling problem.
