Abstract

The invention discloses an aging-resistant silane cross-linked polyethylene insulating composite material. The aging-resistant silane cross-linked polyethylene insulating composite material is characterized by being prepared from, by weight, 120-150 parts of low-density polyethylene resin, 1-2 parts of nano-zinc oxide, 10-15 parts of barite powder, 10-15 parts of kaolin, 2-4 parts of linear phenolic resin, 2-3 parts of polypropylene glycol, 0.3-0.5 part of methylene diphenyl diisocyanate, 3-5 parts of castor oil, 0.3-0.5 part of monoglyceride citrate, 0.3-0.5 part of butylated hydroxytoluene, 2-4 parts of ethylene bis stearamide and 3-6 parts of silane complexing agents. The silane cross-linked polyethylene insulating composite material is good in strength and toughness, good in weather resistance, water resistance and corrosion resistance, excellent in aging resistance, long in service life and good in comprehensive performance.

Description

technical field [0001] The invention relates to the field of composite materials, in particular to an aging-resistant silane crosslinked polyethylene insulating composite material and a preparation method thereof. Background technique [0002] Polyethylene has a large output, abundant sources, and low price. It is a resin with a wide range of uses. However, polyethylene has low compatibility, insufficient weather resistance and mechanical properties, and poor overall performance, which needs to be improved. Among them, cross-linking modification of polyethylene is one of the important means to improve the performance of polyethylene, which can improve the mechanical properties, chemical resistance and crack resistance of polyethylene products, and broaden the application range of polyethylene. [0003] Polyethylene cross-linking technologies include radiation cross-linking, peroxide cross-linking, silane cross-linking, etc. Among them, silane cross-linking polyethylene has ...
