Abstract

The invention discloses anti-icing paint and a preparation method thereof. The anti-icing paint comprises, based on 100% by mass, 30%-50% of organic silicon resin, 5%-30% of fluorine-containing micropowder and additives. By organically combining low surface energy with the organic silicon resin and the fluorine-containing micro powder, surface energy of the paint is reduced synergistically, strength and wear resistance of the paint are enhanced, hydrophobicity of the paint is increased, anti-icing property of the paint is enhanced, icing hazards caused by icing formed on base surfaces in sleet, low-temperature environments and the like can be avoided, and the anti-icing paint can be applied to the fields of power grid facilities including power transmission lines of power grids, power grid towers, optical communication cables, power grid insulators and the like.

Description

technical field [0001] The invention relates to an anti-icing coating, in particular to an anti-icing coating and a preparation method thereof. Background technique [0002] High-voltage power grid lines, towers, insulators, communication optical cables, etc. are prone to icing under conditions such as rain, snow, and low temperature, which will cause the vertical load of the power grid to be overloaded, and then tower collapses, disconnections, and until the overall structure collapses, the power grid will be paralyzed. It threatens the stability of the power communication network and the safe operation of various related industries. The traditional deicing methods currently applied to power grid systems include (1) manual deicing, (2) mechanical deicing, (3) thermal deicing, (4) electromagnetic wave deicing, etc. Due to the disadvantages of low cost, high cost, dangerous operation, and limited scope of application, it cannot be an effective solution to the problem of anti...
