Abstract

The invention discloses a silicon-containing polyimide antistatic antifouling coating and a preparation method and application thereof, and belongs to the technical field of coatings. The silicon-containing polyimide antistatic antifouling coating comprises the following components by weight: 45-60 parts of silicon-containing polyimide resin, 10-15 parts of a filler, 3-8 parts of a flame retardant, 2-6 parts of a pigment, 2-4 parts of a coupling agent, 1-5 parts of a catalyst, 5-10 parts of a diluent, 5-13 parts of a cross-linking agent and 1-5 parts of a thickener. The coating integrates the antifouling and antistatic characteristics, can be used on the surface of electric porcelain of electric insulation equipment such as an insulator, forms a compact coating layer after being cured, has excellent antifouling and antistatic effects, radically solves the pollution flashover phenomenon, effectively ensures smooth operation of a power grid, reduces the maintenance cost, and ensures normal power supply.

Description

technical field [0001] The invention relates to the technical field of coatings, in particular to a silicon-containing polyimide antistatic and antifouling coating and its preparation method and application. Background technique [0002] The electric porcelain surface of the insulation equipment of the power system will inevitably occur in the natural environment, the adhesion of ice, snow and rain, and the long-term adhesion will destroy the insulation performance of the insulation equipment, and pollution flashover will occur. Under severe weather conditions, flashover will occur along the wet insulator surface, resulting in pollution flashover accidents in the power system. The occurrence of pollution flashover will not only affect the normal operation of the power system, but also increase the workload of power personnel. Increased maintenance costs, and even safety accidents in serious cases. However, the existing permanent form-in-place anti-fouling flashover composit...
