Abstract

The invention discloses an anti-icing insulator coating and a preparation method thereof, and relates to the technical field of coatings. The coating comprises, by weight, 20-32 parts of fluorosilicone modified acrylic resin, 30-46 parts of modified silicone resin, 6-14 parts of a modified polyperfluorinated ethylene propylene emulsion, 3-7 parts of modified nano-silica, 2-6 parts of hexamethyldisilazane, 1-5 parts of a modified composite filler, 10-20 parts of n-butyl acetate and 10-30 parts of propylene glycol methyl ether acetate. The coating has the advantages of obvious delayed icing effect, great reduction of the icing amount, easiness in deicing, reduction of the influence of ice and snow weather on power equipment, facilitation of improvement of the operation reliability of a powertransmission line and prolongation of the normal operation period.

Description

technical field [0001] The invention relates to the technical field of coatings, in particular to an anti-icing insulator coating and a preparation method thereof. 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] Generally speaking, the icing phenomenon of conductors is formed due to various meteorological reasons, which mainly include factors such as temperature, humidity, cold and warm a...
