Abstract

The invention provides a novel electrical insulating material. The material is prepared from, by weight, 3-4 parts of kieselguhr, 2-3 parts of lubricant, 20-30 parts of hydroxyethyl cellulose, 35-45 parts of glass fibers, 10 parts of fire retardant, 20-30 parts of polycarbonate, 20-25 parts of ethylene propylene rubber, 5-8 parts of N-ethyl-N-zinc phenyldithiocarbamate, 2-5 parts of compound modifier, 4-7 parts of plasticizer, 12-13 parts of chitin and 18-20 parts of polydimethylsiloxane. Compared with the prior art, the material has the advantages that the material synthesized through the raw materials is high in tensile strength, can work under different temperature conditions and is extremely low in harmful substance emission during combustion, thereby being an environment-friendly cable insulating material.

Description

technical field [0001] The invention is a novel insulating material for electric power, which belongs to the field of cable equipment. 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, a material that prevents the passage of electric current. Its resistivity is very high, usually in the range of 10-10Ω 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. At present, the application range of electrical insulation materials is getting wider and wider, and the requirements for their performance are getting higher and higher. Insulation performance is only the basic performance it should have, and its mechanical properties, thermal stability and flame retardancy are especially traditional Chinese medicine. Electrical ins...
