Abstract

The invention discloses insulator anti-icing coating and a preparation method thereof. The anti-icing coating is prepared from the following components in parts by mass: 35-45 parts of fluorosiliconeresin, 4-5.5 parts of aluminum oxide, 6-8 parts of silicon dioxide, 2-3 parts of titanium dioxide, 0.3-0.8 part of dispersing agent, 0.4-0.9 part of surfactant, 0.2-0.9 part of de-foaming agent, 0.1-0.5 part of catalyst, 0.02-0.08 part of anti-oxidant, 0.2-0.8 part of curing agent and 30-50 parts of solvent PMA. The preparation method comprises the following steps: separately adding aluminum oxide, silicon dioxide and titanium dioxide into the surfactant, adding absolute ethyl alcohol, stirring until completely wet while adding, ultrasonically stirring and dispersing, drying, wetting and drying by distilling through PMA, stirring and dispersing after mixing fluorosilicone resin with residual PMA, pouring all system solution into a grinder to grind, pouring the de-foaming agent, the anti-oxidant and the catalyst into the grinder to disperse, adding the curing agent to disperse, thereby obtaining anti-icing coating. The anti-icing coating is remarkably improved in hydrophobicity performance, is good in anti-ice effect on a power transmission line, and has surface-drying time, volume resistivity and dielectric strength, which meet standards.

Description

technical field [0001] The invention relates to an anti-icing coating for insulators and a preparation method thereof, and belongs to the technical field of disaster prevention and mitigation for power transmission lines. Background technique [0002] In power transmission and transformation projects, the phenomenon of icing on conductors is common, and the faults caused by icing on transmission lines seriously affect the normal operation of power systems. Icing can cause conductor galloping, tower tilting, collapse, disconnection and insulator flashover, resulting in major accidents. At present, effective measures to prevent insulators from icing are very limited, mainly by changing the suspension mode of the insulator or the structure of the insulator itself, which is costly and ineffective, and there is not much room for structural changes of the insulator due to the influence of the use environment. The current RTV coatings have poor hydrophobicity and cannot solve the ...
