Abstract

The invention discloses a mildewproof and waterproof organosilane crosslinked polyethylene insulated composite material. The mildewproof and waterproof organosilane crosslinked polyethylene insulated composite material is characterized by being prepared from, by weight, 120-150 parts of low-density polyethylene resin, 2-4 parts of phenolic novolac resin, 10-15 parts of vermiculite powder, 10-15 parts of talcum powder, 1-2 parts of styrene-acrylic emulsion, 2-3 parts of polypropylene glycol, 0.3-0.5 part of methylene diphenyl diisocyanate, 1-2 parts of glycerol monolaurate, 0.3-0.5 part of zinc naphthenate, 0.2-0.4 part of propylparaben, 2-4 parts of linseed oil, 3-5 parts of polyethylene wax and 3-6 parts of silane complexing agent. The organosilane crosslinked polyethylene insulated composite material is good in strength, toughness, weather resistance, corrosion resistance, waterproof performance and mildewproof performance, capable of effectively restraining reproduction and growth of mould, suitable for being used in a humid environment and beneficial for keeping sanitation and hygiene of the environment and prolonging the service life of a product.

Description

technical field [0001] The invention relates to the field of composite materials, in particular to a mildewproof and waterproof 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 polyeth...
