Abstract

The invention discloses a low-smoke zero-halogen flame-retardant cable material and a preparation method thereof. The low-smoke zero-halogen flame-retardant cable material consists of the following raw materials in parts by weight: 95-105 parts of chloroprene rubber A90, 10-15 parts of polyurethane, 15-20 parts of nitrile butadiene rubber, 15-25 parts of triethylene glycol di-isooctoate, 2-3 parts of ferrocene, 1-2 parts of N,N'-m-phenylene bismaleimide, 30-35 parts of barium sulfate powder, 1-2 parts of anti-aging agent AW, 1-2 parts of 2-thiol benzimidazole, 5-8 parts of chlorinated paraffin, 1-2 parts of accelerant DM, 0.8-1 part of ammonium trimolybdate, 15-25 parts of nano bauxite, 1-3 parts of polypropylene glycol adipate, 2-4 parts of hydrated zinc borate, 4-6 parts of epoxy butyl oleate, 0.8-1 part of vulcanizing agent DCBP, 2-3 parts of modified sepiolite and 4-6 parts of dipentamethylenethiuram hexasulfide. According to the invention, the produced low-smoke zero-halogen flame-retardant cable material has excellent physical performance, stable size and low shrinkage; and the tensile strength, the tear strength and the resilience force of the product are greatly improved.

Description

technical field [0001] The invention mainly relates to a rubber sheath material and a preparation method thereof, in particular to a low-smoke halogen-free flame-retardant cable material and a preparation method thereof. Background technique [0002] In 2002, the European Union formulated the "Electronic Waste Disposal Law" with two directives, one of which is the "Directive on the Prohibition of the Use of Certain Hazardous Substances in Electrical and Electronic Equipment" (ROHS). The ROHS directive requires that electrical and electronic products put on the EU market after July 1, 2006 must not contain 6 harmful substances including lead, mercury, cadmium, hexavalent chromium, polybrominated biphenyls and polybrominated diphenyl ethers. Correspondingly, at the beginning of 2004, the Ministry of Information Industry of the People’s Republic of China formulated the Measures for the Prevention and Control of Pollution by Electronic Information Products (referred to as th...
