Abstract
The invention discloses PRTV (Persisitent Room Temperature Vulcanized Silicone Rubber)-anti-contamination flashover coating, relating to a coating. The PRTV- anti-contamination flashover coating is prepared from 3%-10% of dihydroxy polymethylvinysiloxane, 12%-20% of dihydroxy polydimethylsiloxane, 0.3%-10% of silicon dioxide nanoparticle, 0.3%-10% of titanium dioxide nanoparticle, 0%-12% of powdery aluminum hydroxide, 0%-3% of powdery antimony oxide, 0%-1% of active calcium carbonate nanoparticle and 50%-65% of diluent. In the invention, by selecting imported materials and introducing an advance production technology, fluorine materials and nanometer materials are organically combined and compounded with a silicon rubber body to make the solidified coating remarkably strengthen the electric decoration resistance, the mechanical strength and the natural aging resisting function besides comprising excellent migration property of hydrophobicity, and the service life of the coating is furthest prolonged.
Description
technical field [0001] The present invention relates to a coating, in particular to a PRTV-anti-fouling flash coating. Background technique [0002] Under severe weather conditions (such as: fog, dew, drizzle, etc.), flashovers will occur along the wet insulator surface, resulting in power system pollution flashover accidents. Pollution flashover threatens the safe and stable operation of the power system. If it is mild, it will affect local power supply. If it is serious, it will affect the power grid, and even cause the entire power grid to crack. The impact of pollution flashover on the power supply system has caused huge losses to the national economy. In particular, the natural accumulation of pollution on the surface of electric ceramics for outdoor equipment in power systems is inevitable. With the development of my country's national economy, air pollution is becoming more and more serious, pollution sources in various places are increasing, and the range of salt de...
