Abstract

The invention discloses self-repairing anti-pollution-flashover paint, and a preparation method and application thereof. The self-repairing anti-pollution-flashover paint comprises the following components in parts by weight: 80-200 parts of hydroxyl-terminated polysiloxane, 5-50 parts of white carbon black, 20-80 parts of a flame retardant, 0-10 parts of pigment, 4-30 parts of a crosslinking agent, 2-15 parts of a coupling agent, 0.03-2 parts of a catalyst, 80-300 parts of a diluent and 20-80 parts of self-repairing microcapsules. The self-repairing anti-pollution-flashover paint disclosed bythe invention can be used to finish a crack repairing process at room temperature without additional conditions, is low in carbon, and is intelligent and environmentally friendly. The electrical insulation level of a repaired material can be greatly improved, and the service life is prolonged.

Description

technical field [0001] The invention relates to the technical field of electric power external insulation protection, and in particular to a self-repairing anti-pollution flashover coating, a preparation method and an application. Background technique [0002] The power industry is a major industry that involves the national economy and the people's livelihood, and the safe and stable operation of the power system is the basic guarantee for Guotai Minan. Insulators are key products used to improve the insulation stability of outdoor power transmission and transformation facilities. The composite insulators are composed of silicone rubber and fillers, with light weight and high dielectric strength, and are widely used in high-voltage power transmission. [0003] Composite insulators have long been subjected to ultraviolet aging, wind and sand wear, high and low temperature aging, and ablation aging of leakage current arcs due to long-term outdoor service, coupled with polluti...
