为了降低无机板材饰面涂膜挥发性有机化合物的含量，且提高其自清洁性及疏水性，利用水性植物基乳液大粒径的特性，研究了水性植物基疏水涂料的颜料体积浓度（PVC）、固化剂以及疏水剂对涂膜性能的影响。结果表明：颜料体积浓度为 40%时，涂膜硬度为 HB，光泽为 6. 3，自清洁性最优；固化剂选择 HW-2100，以及疏水剂 R-75添加量为 1%时，涂膜水接触角最大，疏水性最佳。涂覆水性植物基疏水涂料的无机板材因表面张力小，污染物难附着，易于清洁。

In order to reduce the content of volatile organic compounds in inorganic boarddecorative coating，and improve its self-cleaning and hydrophobic properties，with the large particle size property of waterborne bio-based emulsions，the effects of pigment volume concentration（PVC），curing agents，and hydrophobic additives on the coating performancewere studied. It was concluded that when pigment volume concentration was 40%，the hardness of the coating was HB，the gloss was 6. 3，and the self-cleaning performance indicated the best.When the curing agent was HW-2100 and the addition amount of hydrophobic additive R-75was 1%，the water contact angle of coating was the largest，the coating indicated besthydrophobicity. Inorganic boards coated with waterborne bio-based hydrophobic coatings hadlow surface tension，pollutants were difficult to attach and easy to clean.
