Abstract

The invention provides a high-temperature resistant wear-resistant irradiation cross-linked regenerated-polyolefin / nano-magnesium-hydroxide halogen-free flame-retardant environmental-friendly cable material with high electric properties. The cable material is used for products comprising power cables, mine cables, marine cables, electric equipment lines, locomotive and vehicle cables, and the like. The cable material is produced from following raw materials by weight: 30-40 parts of a regenerated polyolefin, 40-50 parts of a compatilizer, 15-20 parts of an ethylene-propylene-diene monomer (EPDM), 120-150 parts of a nano flame retardant, 3-5 parts of an antismoke agent, 3-3.5 parts of a sensitizer, 1-2 parts of a coupling agent, 1.0-1.5 parts of an antioxidant, 1.5-2 parts of a lubricant and 0.8-2.5 parts of a colorant. According to the cable material and the production method, waste and old plastics are used as the raw materials and an irradiation cross-linking technology and an nano new material are employed, and therefore the cable material has good comprehensive performances comprising high-temperature resistance, wear resistance, high electric properties, oil resistance, high strength, less smoke, no halogen, high flame retardance, good fluidity, etc., and the environmental performance of the cable material meets the requirements of electric wires and cables.

Description

technical field [0001] The invention relates to a high-temperature-resistant, wear-resistant, high-electricity radiation cross-linked regenerated polyolefin / nano-magnesium hydroxide halogen-free flame-retardant environmental protection cable material and a production method thereof, which uses waste polyolefin plastics as raw materials and modifies them for production High value-added, environmentally friendly halogen-free flame-retardant cable material for wire and cable, turning waste into treasure; it does not contain lead (Pb), cadmium (Cd), mercury (Hg), hexavalent chromium ( Cr) heavy metals, polybrominated biphenyls and their ethers and other substances that are contrary to environmental protection requirements. The cable materials produced also have high temperature resistance, high electrical properties, wear resistance, oil resistance, halogen-free, low smoke, flame retardant, environmental protection, and long service life. Background technique [0002] The amoun...
