Problems solved by technology

And the coating can not only be used for spraying in a small amount of work, but also can be treated by adjusting the formula and adopting the dip coating process when the workload is relatively large. The dip coating process is simple and the assembly line operation is implemented, which greatly reduces the work intensity of the workers and solves the problem The drawbacks of the existing operating methods reduce production costs

Abstract

The invention discloses a long-acting anti-pollution flashover coating, belonging to the technical field of chemical engineering. The long-acting anti-pollution flashover coating comprises the following components in parts by weight: 100 parts of base rubber, 45-65 parts of a diluent, 6-11 parts of a crosslinking agent, 1.5-3 parts of color paste, 0.08-0.12 part of a catalyst and 1-2 parts of a coupling agent, wherein each part of the base rubber comprises the following components in parts by weight: 33-49 parts of hydroxy-terminated poly-dimethylsiloxane, 9-19 parts of fumed silica, 26-32 parts of aluminum hydroxide, 6-10 parts of a flatting agent, 3-6 parts of a structural control agent and 4-8 parts of an anti-pollution agent. According to the long-acting anti-pollution flashover coating, the deficiencies that the existing anti-pollution flashover coating is poor in anti-pollution capacity and adhesive force and has lots of drawbacks in a construction process are overcome, the adhering degree of the coating is just right, and a coating layer is not damaged under the action of natural forces such as wind blowing, raining and solarization and does not need to be swept under the normal state in a maintenance period.

Description

technical field [0001] The invention belongs to the technical field of chemical industry, and in particular relates to a long-acting antifouling flashover paint. Background technique [0002] Pollution flashover refers to the fact that the soluble substances of the dirt attached to the insulating surface of electrical equipment gradually dissolve in water under humid conditions, forming a conductive film on the insulating surface, greatly reducing the insulation level of the insulator, and appearing under the action of the electric field Phenomenon of strong discharge. Due to the widespread adoption of EHV transmission and DC transmission technologies in the power system, pollution flashover has become a catastrophic failure that seriously threatens the safe operation of equipment and power grids in the power system, and is listed as the number one security enemy of the power system. Preventing pollution flashover accidents has become a The first priority of grid security o...
