Problems solved by technology

However, both PVC and cross-linked polyethylene have their own limitations in applicable environments, and because halogen-containing cable materials prepared by PVC and the like will produce a large amount of toxic and harmful gases during use, especially when they are burned, they have great impact on the environment. Great pollution, the dioxin produced by the combustion of decabromodiphenyl ether and diphenyl ether is a recognized strong carcinogen, and the call for banning halogen-containing insulating materials such as polyvinyl chloride is getting louder and louder
Halogen-containing materials, especially polyvinyl chloride materials, have been dominating the market of low-voltage insulation materials due to their superior physical properties and low prices, and polyethylene materials are used instead. However, due to the poor heat resistance of ordinary polyethylene products, the long-term use temperature is only 70 ℃, if you want to meet the use temperature above 90 ℃, you must crosslink it, which causes a lot of inconvenience to the production of insulating materials and cable molding, and also increases the production cost

Description

technical field [0001] The invention relates to a halogen-free flame-retardant polypropylene high-speed wear-resistant insulation material for automobile primary wires, and belongs to the technical field of halogen-free flame-retardant polypropylene compositions. Background technique [0002] In the prior art, PVC is used as a protective material for automotive wires, and most wires that cannot use PVC are generally distributed in high-temperature environments such as engine inner chambers. They generally use cross-linked polyethylene as a protective material. However, both PVC and cross-linked polyethylene have their own limitations in applicable environments, and because halogen-containing cable materials prepared by PVC and the like will produce a large amount of toxic and harmful gases during use, especially when they are burned, they have great impact on the environment. Great pollution, the dioxin produced by the combustion of decabromodiphenyl ether and diphenyl ether...
