Moistureproof insulation material for electrical engineering

Abstract

The invention discloses a moistureproof insulation material for electrical engineering. The material comprises an inner layer and an outer layer. The inner layer is prepared from the following raw materials in parts by weight: 10-16 parts of quartz sand, 16-22 parts of aluminum oxide, 16-22 parts of polyallylamine resin, 3-9 parts of dimethylformamide, 1-4 parts of butyl rubber and 3-9 parts of nano silicon dioxide. The outer layer is prepared from the following raw materials in parts by weight: 15-22 parts of epoxy resin, 10-17 parts of polyamide resin, 20-28 parts of glass fiber, 2-6 parts of ethylene propylene diene monomer rubber, 0.5-1.2 parts of 2-mercaptobenzimidazole, 1-4 parts of nano zinc oxide, 10-18 parts of silicon nitride, 2-9 parts of hydrogenated nitrile-butadiene rubber, 5-11 parts of aluminum nitride and 5-11 parts of polyethylene. The moistureproof insulation material is composed of the inner layer and outer layer; the outer layer achieves the moistureproof effect under the combined actions of the components; and the material has steady insulating property under the combined actions of the components of the inner layer.

Description

Technical field: [0001] The invention relates to a moisture-proof insulating material for electrical engineering, belonging to the technical field of electrical engineering. Background technique: [0002] According to the national standard GB2900.5, the definition of insulating material is: "the material used to make the device electrically insulated". That is, materials that prevent the passage of electric current. Its resistivity is very high, usually in the range of 10^9~10^22Ω·m. As in an electric motor, the insulation around the conductors isolates the turns from each other and from the grounded stator core to ensure safe operation of the motor. [0003] At present, the power industry is in a period of rapid development, and electrical products have been popularized in various industries. The insulation requirements of electrical products are very high. Although there are many types of surface insulation materials on the market, the performance is relatively single, ...

Problems solved by technology

The insulation requirements of electrical products are very high. Although there are many types of surface insulation materials on the market, the performance is relatively single, and their uses are highly targeted. They cannot meet the requirements of moisture-proof, anti-corrosion, high-temperature resistance, and insulation. Insufficient insulation level restricts the development of electrical appliances and motor industries
