Abstract

The invention discloses an organosilane crosslinked polyethylene insulating composite material. The material is characterized by being prepared from the following raw materials in parts by weight: 120-150 parts of low-density polyethylene resin, 3-5 parts of bisphenol A epoxy resin, 2-4 parts of phenolic novolac resin, 10-15 parts of waste glass powder, 10-15 parts of coal gangue powder, 2-3 parts of polypropylene glycol, 0.3-0.5 part of diphenyl methane diisocyanate, 2-4 parts of polyglycerol polyricinoleate, 1-2 parts of barium petroleum sulfonate and 3-6 parts of silane compound. The organosilane crosslinked polyethylene insulating composite material has the advantages of good strength and toughness, good weather resistance, water resistance and corrosion resistance performance, superior wear resistance, moisture resistance and high temperature resistance performance, high use safety and suitability for mine electric wires and cables.

Description

technical field [0001] The invention relates to the field of composite materials, in particular to a silane crosslinked polyethylene insulating composite material for coal mines 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 has th...
