Research progress of superhydrophobic coatings based on silicone rubber surface

Silicone rubber has excellent insulation properties such as good hydrophobic mobility and anti pollution flashover performance. It plays an important role in the power system provides guarantee for reliability of supply. However, due to erosion various harsh environments, especially wet environments rain snow, a large amount dirt water are easily attached surface insulating parts. not only reduces its hydrophobicity mobility, but also greatly shortens service life. There even serious leakage current problems. Especially low temperature environment, lot snow will occur at accessories In order solve this problem, super self-cleaning coating based on silicone came into being. The preparation principle model superhydrophobic reviewed paper. By comparing different methods, advantages, disadvantages application prospects analyzed, existing problems challenges put forward according technologies, so lay theoretical foundation preparing coatings with performance future.
