Abstract

The invention discloses titanate coupling agent modified pollution-flashover-preventing fluorocarbon paint which comprises the following components in parts by weight: 30-50 parts of fluorocarbon resin, 10-30 parts of filler, 1-10 parts of pigment, 3.5-10 parts of curing agent, 2-10 parts of coupling agent, 0.03-3 parts of assistant, 35-45 parts of solvent and 0.001-0.1 part of drying agent. The invention also discloses a preparation method of the fluorocarbon resin paint. The static contact angle theta of the fluorocarbon resin paint can be up to 118 degrees; and the fluorocarbon resin paint has favorable hydrophobicity and hydrophobic migration performance and high pollution flashover preventing performance, thus ensuring that the physical / chemical properties and electric properties of a prepared coating can meet pollution flashover preventing conditions. The invention is used for insulator pollution flashover prevention, and solves the problem of insulator pollution flashover of a high-voltage transmission line.

Description

technical field [0001] The invention relates to an antifouling flashover fluorocarbon coating, in particular to an antifouling flashover fluorocarbon coating modified by a titanate coupling agent. The invention also relates to a preparation method of the antifouling flash fluorocarbon coating. Background technique [0002] Anti-pollution flashover coating is an important means to prevent pollution flashover of external insulation of power equipment. In recent years, with the increase of industrial emissions and the aggravation of environmental pollution, pollution flashover of power transmission and transformation equipment has become more and more frequent. After the creepage distance of transmission line insulator strings has been generally adjusted, the problem of anti-pollution flashover of substation equipment has become more prominent. The use of anti-pollution flashover coatings in substations has also increased day by day, and has become an important means of anti-p...
