Abstract

The invention discloses a modified high-density polyethylene flame-retardant cable sheath. The modified high-density polyethylene flame-retardant cable sheath is made of raw materials including modified high-density polyethylene, neoprene, butyl rubber, dicumyl peroxide, high-abrasion-resistance carbon black, antimony trioxide, nano calcium carbonate, magnesium carbonate, talc powder, furnace slag powder, alum powder, chlorinated paraffin, trioctyl trimellitate, aluminum triphosphate, aluminum stearate, anti-aging agents ODA, accelerators TMTM, vulcanizing agents DCBP, antioxidants and benzotriazole. The modified high-density polyethylene flame-retardant cable sheath has the advantages that the modified high-density polyethylene flame-retardant cable sheath is mainly made of the modified high-density polyethylene, fillers and additives are added into the high-density polyethylene to prepare the modified high-density polyethylene flame-retardant cable sheath, and accordingly the modified high-density polyethylene flame-retardant cable sheath is excellent in flame-retardant performance, good in toughness and high in hardness.

Description

technical field [0001] The invention relates to a cable sheathing material, in particular to a modified high-density polyethylene flame-retardant cable sheathing material. Background technique [0002] The wire and cable industry is the second largest industry in China after the automobile industry, and the product variety satisfaction rate and domestic market share both exceed 90%. Worldwide, China's wire and cable output has surpassed that of the United States, becoming the world's largest producer of wire and cable. With the rapid development of China's wire and cable industry, the number of new enterprises has been increasing, and the overall technical level of the industry has been greatly improved. The continuous and rapid growth of China's economy has provided a huge market space for cable products. The strong temptation of the Chinese market has made the world focus on the Chinese market. In just a few decades of reform and opening up, China's cable manufacturing in...
