Abstract

The invention discloses a high-weatherability silane-crosslinked polyethylene insulation composite material, which is composed of the following raw materials in parts by weight: 120 to 150 parts of low-density polyethylene resin, 2 to 4 parts of linear phenolic resin, 2 to 4 parts of titanium dioxide, 5 to 10 parts of diatomite, 10 to 15 parts of lightly-burned dolomite powder, 0.5 to 1 part of octyl phenol polyoxyethylene ether, 0.3 to 0.5 part of benzotriazole, 2 to 3 parts of polypropylene glycol, 0.3 to 0.5 part of diphenyl-methane-diisocyanate, 1 to 2 parts of Turkey red oil, 2 to 4 parts of tri-octyl tri-meta-benzoate, and 3 to 6 parts of silane coupling agent. The provided composite material has the advantages of high strength and toughness, good waterproof and corrosion-resistant performance, excellent weatherability, high safety, long service life, and wide application range, and is suitable for being used in severe environment.

Description

technical field [0001] The invention relates to the field of composite materials, in particular to a highly weather-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 polyethyl...
