[0020] In view of the poor comprehensive performance of fluorocarbon resin anti-fouling flashover coatings in the prior art, the difficulty of preparation methods, and less attention to problems such as corrosion and aging of coatings, in one or some embodiments of the present disclosure, an anti-fouling flashover coating is provided Coating comprises the raw material of following parts by weight:

[0021] 90-120 parts of fluorocarbon resin;

[0022] 90-120 parts of butyl acetate;

[0023] 5-20 parts of reinforcing filler;

[0024] 40-80 parts of inorganic flame retardant;

[0025] 10-20 parts of pigment;

[0026] 0.2 to 1 part of dispersant;

[0027] 0.1 to 0.5 parts of defoamer;

[0028] 0.1-0.5 parts of leveling agent;

[0029] 8 to 16 parts of curing agent.

[0030] The inorganic flame retardant and dispersant make the fluorocarbon resin fully cross-linked, which is conducive to the formation of a dense barrier layer and inhibits the degradation of the fluorocarbon ...

Abstract

The invention relates to the field of anti-pollution flashover coatings, and particularly provides an anti-pollution flashover coating and a preparation method thereof. The anti-pollution flashover coating comprises the following raw materials in parts by weight: 90-120 parts of fluorocarbon resin, 90 to 120 parts of butyl acetate, 5-20 parts of a reinforcing filler, 40 to 80 parts of an inorganicflame retardant, 10 to 20 parts of pigment, 0.2-1 part of a dispersing agent, 0.1 to 0.5 part of an antifoaming agent, 0.1 to 0.5 part of leveling agent, 8-16 parts of curing agent. The preparation method of the anti-pollution flashover coating comprises the following steps: adding the dispersing agent into butyl acetate, stirring, adding the reinforcing filler, the inorganic flame retardant andthe pigment filler, carrying out high-power ultrasonic dispersion to obtain pigment filler dispersion liquid, pouring the pigment and filler dispersion liquid into a grinding machine, blending and grinding with fluorocarbon resin, adding an antifoaming agent and a leveling agent into the grinding system, sieving the obtained mixed liquid through a screen to obtain a coating component A, and beforeuse, mixing and stirring the component A and the curing agent to obtain the product. The coating is good in comprehensive performance and simple to prepare.

Description

technical field [0001] The invention relates to the field of antifouling flashover coatings, and specifically provides an antifouling flashover coating and a preparation method thereof. Background technique [0002] The statements herein merely provide background information related to the present disclosure and may not necessarily constitute prior art. [0003] Because silicone rubber has good hydrophobicity and hydrophobic mobility, it will not form continuous water bands on the surface after being polluted, so it is often used to prepare RTV anti-pollution flashover coatings, and is widely used in the field of external insulation of power equipment Pollution flashover prevention and control. However, RTV anti-fouling flashover coatings are subjected to strong electric fields, ultraviolet rays, and harsh weather under long-term outdoor operating conditions, which will inevitably cause aging, such as peeling, powdering, fading, falling off, and water-repellent degradation,...
