本文将改性后的SiO2粉体与制备的甲基硅树脂微球添加到涂层中，用扫描电镜和接触角仪分析涂层形貌和疏水型的变化。考察了疏水剂在不同涂层基料 中对疏水性的影响，结果表明：在涂层中添加改性后的SiO2与甲基硅树脂微球时，由于提高了涂层表面的粗糙度，故增强了涂层的疏水性。当基料为硅丙乳液时，涂层对水接触角分别为114.87˚和106.12˚；当基料为苯丙乳液时，涂层对水接触角分别为110.92˚和106.18˚；当基料为含氢硅油时，涂层对水接触角分别为124.28˚和130.39˚。在涂层中添加混合疏水剂，比使用单一疏水剂的疏水强，在硅丙涂层中，水接触角为117.02˚，苯丙涂层中，水接触角为115.53˚，当在含氢硅油涂层中时，涂层表面形成微米纳米相结合的阶层结构，大大提高了疏水性，水接触角为137.6˚。 |

| In this paper, we added the modified SiO2 particles and prepared methyl silicone resin microspheres into the coatings. The morphology of the coatings was studied by SEM, while the hydrophobic variation was measured by a contact angle instrument. The influence of hydrophobe in different coating base materials on hydrophobicity was also investigated. The results showed that the hydrophobicity of the coatings was elevated by the improved roughness after the adding of the modified SiO2 and prepared methyl silicone resin microspheres into the coatings. When silicone/acrylic latex was used as base material, the contact angles of the coatings to water were 114.87˚ and 106.12˚ separately; while for styrene/acrylic latex, that angles were 110.92˚ and 106.18˚ separately; and when the base material was changed to hydrogen silicone fluid, that angles were 124.28˚ and 130.39˚separately. The combination of hydrophobe had a stronger (better 应该也可以) hydrophobicity than single hydrophobe. In the silicone/acrylic coatings, the water contact angle was 117.02˚; while in the styrene/acrylic coatings, that angle was 115.53˚; and in the coatings which hydrogen silicone fluid was used, the hydrophobicity was highly improved due to the layered structure of micro-nano combined phases, and the water angle was 137.6˚. |
