摘要

文中以侧链带有活性基团的聚硅氧烷（改性聚硅氧烷）为缓释型憎水防污闪涂料的基础聚合物

研究了涂料配方对涂料憎水性及拉伸强度、自洁性的影响。试验结果表明:改性聚硅氧烷与107硅胶用量最佳比例为40:60

此时涂料具有较优异的憎水性能

涂料平均静态接触角及伸长率最大。通过加入多胺基有机硅氧烷和纳米活性金属氧化物来降低涂层表面的电阻和增加涂层表面光滑度

从而提高涂料自洁性能。

Abstract

In this paper

we used a polysiloxane with active groups in side chain（modified polysiloxane）as the base polymer of sustained-release hydrophobic anti-pollution-flashover coating and studied on the influence of coating’s formulation on its hydrophobicity

tensile strength and self-cleaning property. The experiment results showed that the optimal ratio of modified polysiloxane to hydroxyl-terminated polydimethylsiloxane was 40:60

then coating had relatively excellent hydrophobicity

and the average static contact angle and elongation of the coating reached its maximum. By adding polyamine organosiloxane and active nano metal oxide to reduce the surface resistance of the coating and increase the surface smoothness of the coating

so as to enhance the self-cleaning properties of the coating.
