Abstract

The invention provides a thermoplastic modified polyethylene material suitable for electric insulators, wherein the thermoplastic modified polyethylene material is prepared from the following raw materials by weight: 50-65% of polyethylene, 2-6% of a toughener, 15-20% of an inorganic filler, 15-20% of a bromine-based flame retardant, 1.5-5% of a synergistic flame retardant, 0.6-1.4% of a stabilizer, 0.5-1% of a coupling agent, and 0.2-1% of a lubricant, the raw materials are stirred and mixed in a high-speed mixer, and the mixture is extruded and granulated by a twin-screw extruder to obtain the product. According to the present invention, the thermoplastic modified polyethylene material has advantages of excellent comprehensive performance, stable flame retardancy, low density and smoothsurface property, is the thermoplastic material, can be recovered and reused, and meets the environmental protection trends; and with the application of the thermoplastic modified polyethylene material in the preparation of insulator product, the process is simple, the production cycle is short, the production environment is free of dust, and the product can be recovered and reused after the usedlife is achieved and the product is rejected so as not to cause white pollution.

Description

technical field [0001] The invention relates to a modified polyethylene material, in particular to a thermoplastic modified polyethylene material suitable for electric insulators, and belongs to the technical field of electric power. Background technique [0002] At present, most insulators at home and abroad are ceramic, glass or composite insulators. Both ceramic and glass insulators are fragile, inconvenient for handling and transportation, and require a lot of manpower and material resources. At the same time, both ceramic and glass insulators are heavy, and the loads of transmission line cables and towers are relatively large, which consumes a lot of energy during production and causes a lot of dust emissions. Does not meet international energy conservation and environmental protection requirements. Composite insulators are mostly silicone rubber insulators. This silicone rubber material is a high-temperature vulcanized rubber with low production efficiency. After the...
