摘要

将纳米二氧化硅和微二氧化硅颗粒与硅橡胶混合。对所得材料在斜面上的侵蚀损伤、原始样品的表面粗糙度和接触角进行了比较。结果表明，纳米二氧化硅填充室温硫化硅橡胶(RTV)比微二氧化硅填充的室温硫化硅橡胶(SR)具有更高的抗冲蚀性能，接触角的测量结果表明，纳米二氧化硅填充的原始样品的疏水性略低于微二氧化硅填充的样品。纳米二氧化硅填充样品的表面粗糙度低于微二氧化硅填充样品，并且可以预期这种纳米二氧化硅填充的RTV SR材料的污染积累较少。这些初步实验结果表明，纳米二氧化硅填充的RTV SR比微二氧化硅填充的RTV SR更适合污染环境

Use of nano-silica in silicone rubber for ceramic insulators coatings in coastal areas

Nano-silica and micro-silica particles were mixed with silicone rubber. The resulting materials were compared with respect to erosion damage in inclined plane, and surface roughness and contact angle of virgin samples. Results have shown that nano-silica filled room temperature vulcanized (RTV) silicone rubber (SR) has higher erosion resistance than micro-silica filled RTV SR. The measurement of the contact angle of virgin samples has shown slightly lower hydrophobicity for the nano-silica filled samples than micro-silica filled samples. Surface roughness in nano-silica filled samples is lower than micro-silica filled samples, and one could expect less contamination accumulation of such nano-silica filled RTV SR materials. These preliminary laboratorial results indicate that the nano-silica filled RTV SR is better suited for contaminated environments than micro-silica filled RTV SR
