Abstract

The invention discloses a rick husk modified silane-crosslinked polyethylene insulation composite material, which is characterized by being prepared from the following raw materials in parts by weight: 120 to 150 parts of low-density polyethylene resin, 20 to 30 parts of rick husk, 5 to 10 parts of diatomite, 2 to 4 parts of sodium silicate, 2 to 4 parts of linear phenolic resin, 2 to 3 parts of polypropylene glycol, 0.3 to 0.5 part of diphenyl-methane-diisocyanate, 1 to 2 parts of cotton seed oil, 1 to 2 parts of hydroxy silicone oil, 0.5 to 1 part of chlorinated paraffin, and 3 to 6 parts of silane complexing agent. The provided silane-crosslinked polyethylene insulation composite material has the advantages of high strength and toughness, good weatherability, excellent water resistant and corrosion resistant performance, energy saving property, and environment-friendliness, and can generate social benefit and economic benefit.

Description

technical field [0001] The invention relates to the field of composite materials, in particular to a rice husk modified 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 ha...
