Pollution/rain flashover resistant paint and preparation method thereof

Abstract

The invention discloses a pollution / rain flashover resistant paint. The paint comprises the following components in parts by weight: 40-50 parts of silicon rubber, 40-50 parts of MQ silicon resin, 50-80 parts of a solvent, 5-20 parts of fillers, 50-70 parts of silicone acrylate resin, 0.5-3 parts of a curing agent and 3-6 parts of catalysts, wherein the silicon rubber is hydroxyl-terminated polydialkylsiloxane; the MQ silicon resin is methyl hydrogen-containing MQ silicon resin with M-Q ratio being 0.6-0.9; the solvent is one or mixture of butyl acetate, ethyl acetate and methyl acetate; the fillers are one or more of nano calcium carbonate, fumed silica, titanium dioxide and silica micropowder, which are subjected to surface modification treatment by silane; the curing agent is zirconiumisooctoate, cobalt isooctoate or cobalt naphthenate; and the catalysts are tin compounds or organic titanium compounds. The invention also discloses a preparation method of the pollution / rain flashover resistant paint.

Description

Technical field

[0001] The invention relates to an anti-pollution flash and rain flash paint and a manufacturing method thereof. Background technique

[0002] At present, the anti-pollution flashover coating widely used in China's power industry is room temperature vulcanized silicone rubber material. This type of material has been used in the power industry since the 1980s. Because of its excellent water repellency, even after the surface of the insulator is contaminated, The silicone rubber material can still migrate to the surface of the contaminant, so that the contaminated insulator still has good water repellency, so that the water exists in the form of particles on its surface and cannot form a continuous water film, thereby inhibiting the wetting of the contaminated layer. The purpose of reducing leakage current and increasing pollution flashover voltage. The anti-pollution flashover silicone rubber material in the prior art is generally composed of necessary components ...
