Abstract

The invention discloses a polymer insulator material. The polymer insulator material is prepared from, by mass, 40%-55% of polyethylene, 5%-15% of polypropylene, 10%-15% of methyl silicone rubber and15%-45% of filler. The polymer composite insulator material not only can meet the requirements of electrical characteristics and mechanical properties of an insulator but also can meet the life requirement, the electric deterioration rating of the tracking resistance is larger than or equal to 1A4.5, the maximum deterioration depth is less than 2mm, the material has an anti-fouling self-cleaning function, is high in cost performance, saves the energy, is environmentally friendly, does not cause pollution and can be recycled after the service life is ended. The invention also discloses a preparation method of the polymer insulator material.

Description

technical field [0001] The invention belongs to the technical field of insulator materials, and in particular relates to a polymer insulator material and a preparation method of the polymer insulator material. Background technique [0002] With the development of the economy, the construction of the power grid and its power facilities is also speeding up, and the amount of insulators is also increasing. However, traditional porcelain insulators have many shortcomings: (1) Production generally requires mining a large amount of clay. In the process, the traditional kiln sintering not only consumes energy but also emits a large amount of smoke and dust pollution, which seriously damages the ecological environment; (2) the production cycle is long, the process is many, and it is difficult to realize mechanized and automated production; (3) affected by the raw materials Material limitations, especially the quality fluctuations of mineral raw materials have a great impact, and the...
