Abstract

The invention discloses a corrosion-resistant silane crosslinked polyethylene insulation composite material. The corrosion-resistant silane crosslinked polyethylene insulation composite material is prepared from 120-150 parts by weight of low density polyethylene resin, 3-5 parts by weight of phenolic novolac resin, 5-10 parts by weight of glass fibers, 10-15 parts by weight of barite powder, 1-2 parts by weight of titanium dioxide, 2-3 parts by weight of polypropylene glycol, 0.3-0.5 parts by weight of diphenyl-methane-diisocyanate, 1-2 parts by weight of hydrogenated castor oil, 1-2 parts by weight of N,N'-ethylenebis(stearamide) and 3-6 parts by weight of a silane complexing agent. The corrosion-resistant silane crosslinked polyethylene insulation composite material has the advantages of good strength, good toughness, weatherability, water resistance, excellent corrosion resistance, high safety and wide application range.

Description

technical field [0001] The invention relates to the field of composite materials, in particular to a corrosion-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 h...
