The exterior wall paint was prepared with silicone modified acrylate emulsion , silicone oil modified wollastonite and self-made emulsifying wax as main raw materials. The response surface experiment method was applied to investigate the effects of the three main raw materials on the contact angle of the finished coating. The results showed that the optimum ratio of pigment to base material, use level of silicone-acrylic emulsion and use level of emulsifying wax were separately 2.5, 20 g and 2.5 g under which the contact angle of the finished coating was 139.2 °and the coating exhibited good hydrophobic effect. The second multiple regression equation established by use of software of Design-expert 6.0 was in good agreement with the experimental results and can be applied to predict the contact angle under different level groups of the three main raw materials.
