Abstract

The present invention relates to an anti-icing composite nano-coating and an application thereof. The anti-icing composite nano-coating is composed of organic fluorine-silicon composite polymer material, nano-material, curing agent, solvent and filler, the weight percentages of which are as follows: 1 to 98 percent of organic fluorine-silicon composite polymer material, 1 to 92 percent of nano-material, 1 to 50 percent of curing agent, 0 to 90 percent of solvent and 0 to 50 percent of filler. The doses of substances are uniformly mixed and ground so that the anti-icing composite nano-coating is prepared. The anti-icing composite nano-coating can be used to prevent the power transmission lines, conductors, conductor metal fittings, pole towers, stayguys, stayguy fixtures and other power and communication facilities of electric power systems and communication networks from being iced.

Description

technical field [0001] The invention relates to a kind of anti-icing nanocomposite paint and its application. The invention belongs to the technical fields of chemical engineering and materials. Background technique [0002] With the rapid development of modern industry, the reliability requirements for grid power supply are getting higher and higher. 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 mechanical and electrical accidents such as conductor galloping, disconnection, tower collapse, and flashover. Ice and snow on transmission lines seriously threaten the safe and reliable operation of power and communication networks. [0003] Ice and snow accumulation on transmission lines threaten the safe operation of power and communication networks. In Russia, Canada, the United Sta...
