Abstract

The invention discloses a peanut shell powder modified silane crosslinked polyethylene insulation composite material. The peanut shell powder modified silane crosslinked polyethylene insulation composite material is prepared by the raw materials in parts by weight as follows: 120-150 parts of low density polyethylene resin, 10-15 parts of peanut shell powder, 10-15 parts of shell powder, 2-4 parts of borax, 2-4 parts of linear phenolic resin, 2-3 parts of polypropylene glycol, 1-2 parts of oleamide, 1-2 parts of polyoxyethylene rosin ester, 0.3-0.5 parts of diphenyl methane diisocyanate, 2-4 parts of rice bran oil and 3-6 parts of silane compound. The silane crosslinked polyethylene insulation composite material has good intensity and toughness, good weather ability and water-tolerant, decay resistance, good economical efficiency and strong practicability, and the raw material sources are wide.

Description

Technical field [0001] The invention relates to the field of composite materials, in particular to a peanut shell powder modified silane crosslinked polyethylene insulating composite material and a preparation method thereof. Background technique [0002] Polyethylene is a resin with a wide range of uses due to its large output, abundant sources and low price. However, the compatibility of polyethylene is low, the weather resistance and mechanical properties are insufficient, the overall performance is poor, and the performance needs to be improved. Among them, the cross-linking modification of polyethylene is one of the important means to improve the properties 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 technology includes radiation cross-linking, peroxide cross-linking, silane cross-linking, etc. Among them, ...
