Abstract

The invention relates to a nanometer coating used for preventing icing of a high tension transmission line and application thereof. The nanometer coating is prepared through the following steps: weighing, by weight, 10 to 15% of a high-molecular resin, 20 to 25% of titanium dioxide, 30 to 35% of silica, 3 to 5% of diamond-like carbon and 19 to 32% of a solvent; then compounding and uniformly mixing the high-molecular resin, titanium dioxide, silica and diamond-like carbon and carrying out grinding to obtain a particle with a particle size of 1 to 100 nm; and finally, adding the raw materials uniformly mixed and ground into the solvent and carrying out full stirring so as to obtain the nanometer coating used for preventing icing of the high tension transmission line. The coating provided by the invention allows the high tension transmission line to have the advantages of fouling resistance, icing resistance, high wear resistance and the like, provides a long-acting, high-efficiency, convenient, economic and feasible approach for active resistance to ice and snow disasters, realizes delaying and prevention of icing of super-cooled droplets on the high tension transmission line and enables no icing or little icing to be generated on the high tension transmission line in snowy weather.

Description

technical field [0001] The invention relates to a kind of anti-icing nanocomposite coating and its application, in particular to a nano-coating for high-voltage transmission line anti-icing and its application, belonging to the fields of chemical engineering and material technology. Background technique [0002] In recent years, due to the influence of global climate change, the uncertain factors of climate conditions have increased, and the frequency and intensity of extreme weather events have shown an increasing trend. The failure of power grids under disastrous weather conditions has increased significantly, especially in recent years. Tripping faults increased significantly, seriously threatening the safe operation of the line. Icing and snowing are natural phenomena, but icing is a natural disaster for power systems, and icing lines seriously threaten the safe operation of power systems. The hazards caused by icing on transmission lines to the power system include mec...
