Abstract

The invention discloses a high-strength anti-scraping silane crosslinked polyethylene insulation composite. The composite is characterized by being produced through raw materials of, by weight part, 120 to 150 of low-density polyethylene resin, 2 to 4 of linear phenol-formaldehyde resin, 3 to 5 of boron nitride, 1 to 2 of nanometer aluminum alloy, 10 to 15 of talcum powder, 5 to 10 basalt powder, 2 to 3 of polypropylene glycol, 0.3 to 0.5 of diphenyl-methane-diisocyanate, 0.3 to 0.5 of triglycidyl isocyanurate, 2 to 4 of magnesium stearate, 3 to 5 of palm oil and 3 to 6 of silane complexing agents. The composite has the advantages of being good in strength and toughness, good in weather resistance and anti-corrosion performance, high good in anti-scraping and anti-scratching performances, good in use performance and wide in application range.

Description

technical field [0001] The invention relates to the field of composite materials, in particular to a high-strength scratch-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 po...
