Abstract

The invention provides an anti-pollution-flashover fluorocarbon coating. The anti-pollution-flashover fluorocarbon coating is a primer-free coating and mainly comprises the following components in percentage by weight: 30-70% of fluorocarbon resin, 35-45% of a self-prepared mixed solvent, 10-30% of pigment, 1-5% of a coupling agent, 0.03-2% of auxiliaries, 1-10% of a curing agent, and 0.03-0.2% of a catalyst. According to the anti-pollution-flashover fluorocarbon coating, by researching a coupling agent addition process, a modified nanofiller addition process and a defoaming process, the hydrophobic property of the coating is increased; the external examination electric insulation performance of the modified coating can satisfy anti-pollution-flashover requirements; and the anti-pollution-flashover fluorocarbon coating has good anti-pollution-flashover property and can be applied to pollution-flashover prevention of high-voltage insulators of an electric transmission and distribution circuit.

Description

technical field [0001] The invention belongs to the paint industry, in particular, the invention relates to an antifouling flash fluorocarbon paint. Background technique [0002] Pollution flashover of insulators in power transmission and transformation equipment is a common accident, which seriously affects the safe and economical operation of power transmission and transformation lines. Preventing pollution flashover of insulators is an important task to ensure the safe operation of power system lines. At present, the anti-fouling flashover coatings that have been used mainly include: room temperature vulcanization silicone rubber (RTV), silicone oil coatings, silicone grease coatings, ground wax coatings, etc. However, these coatings have a short service life, affect the appearance of insulators, and have poor dust resistance. At present, the silicone rubber anti-pollution flashover coatings widely used in power systems are not very effective. Since the application of ro...
