A nano-SiO_2 modified styrene-acrylic composite emulsion was prepared through grafting techniques-organic and inorganic compounding of nano-SiO_2 colloidal and styrene acrylic emulsion with silane coupling agent, Orthogonal experiment was used to study the influence of composite emulsion, fillers and ration of additives. Experimently the main properties of the composite coatings, such as, weathering, washability, adhesion and contamination resistance, etc. were investigated. The results showed that through orthogonal experiment,optimized coating formula was 14: A 32%,B 2.5%,C 7.8%,D 7.8%,E 13%,F 3.9 %,G 0.78%;The adhesion was up to 100%,the washability was up to 22576 times, hiding power 351.675 g/m~2, contamination resistance 95.8%.
