Abstract
The invention discloses a weather-proof polyolefin wire cable material and a preparation method thereof, the cable material comprises the raw material by weight: 60-80 parts of LDPE, 15-25 parts of EVA, 10-15 parts of SEBS, 14-18 parts of magnesium hydroxide, 2-4 parts of stearic acid, 1-2 parts of zinc oxide, 5-10 parts of zinc borate, 1-2 parts of lead sulfate tribasic, 1-2 parts of vinyltriethoxysilane, 4-8 parts of octyl epoxy stearate, 0.5-1 part of light stabilizing agent GW-4800.5, 1-1.5 parts of anti-oxidant 215, 0.5-1 part of dibutyltin dilaurate, 0.5-1 part of dicumyl peroxide, 20-25 part of aluminum silicon black, 10-15 parts of nano barite, 5-10 parts of nano diatomite and 4-8 parts of composite filling material. The polyolefin cable material has excellent flame retardation performance, physical and mechanical properties and weatherability, can be widely used in electric power cable, communication cable, control cable, optical cable , subway cable, insulation or sheath, electronic wire, automobile and the like, and has the advantages of environmental protection and durable performance.
Description
technical field [0001] The invention relates to a cable material and a preparation method thereof, in particular to a weather-resistant polyolefin wire and cable material and a preparation method thereof. Background technique [0002] With the rapid development of industry, polyolefin wires and cables have been widely used in various fields. However, the low-smoke, halogen-free and flame-retardant polyolefin wires and cables produced in my country still have problems of poor weather resistance and mechanical properties. Therefore, it is of great practical significance to carry out research on weather-resistant halogen-free flame-retardant polyolefin wire and cable materials to improve their mechanical properties and weather resistance. Contents of the invention [0003] The object of the present invention is to provide a weather-resistant polyolefin wire and cable material and a preparation method thereof to improve the mechanical strength and weather resistance of the pol...
