High-strength weather-resistance and flame-retardance EPDM cable material

Abstract

The invention discloses a high-strength weather-resistance and flame-retardance EPDM cable material. The high-strength weather-resistance and flame-retardance EPDM cable material is prepared from, by weight, 35-60 parts of EPDM, 20-30 parts of a fluorine-containing polymer, 20-25 parts of butadiene styrene rubber, 6-19 parts of hard clay, 2-6 parts of a mono-alkoxy type titanate coupling agent, 5-10 parts of aluminum hydroxide, 4-6 parts of red phosphorus masterbatch, 3-4 parts of antimony trioxide, 0.3-0.6 part of sulfur, 0.3-0.6 part of diisopropylbenzene peroxide, 1.5-1.8 parts of N-cyclohexyl-2-benzothiazole sulfonamide, 1.2-1.3 parts of trimethylolpropane trimethacrylate, 1.1-1.5 parts of an anti-aging agent H, 1.1-1.5 parts of an anti-aging agent DFC-34, 6-10 parts of zinc oxide and 2-5 parts of melamine cyanurate. The high-strength weather-resistance and flame-retardance EPDM cable material has high elasticity and high strength and is excellent in flame retardance, abrasion resistance, ozone corrosion resistance and weather resistance.

Description

technical field [0001] The invention relates to the technical field of rubber materials, in particular to a high-strength weather-resistant and flame-retardant EPDM cable material. Background technique [0002] With the increasing popularity of wind power generation, it has led to the development of wind power generation related products. Since wind power generation systems are often used under harsh environmental conditions, such as large temperature differences and ultraviolet radiation, especially in plateau areas, the temperature difference between day and night is large. , and the cable should be twisted with the rotation of the fan. If special cables suitable for the surrounding environment are not used, ordinary wires and cables or traditional wind energy cables will undergo long-term sunlight exposure, wind and rain, ozone erosion and twisting in the fan. Cracks will appear on the surface, and the cable material will age rapidly when the ambient temperature range is ...

AI Technical Summary

Problems solved by technology

[0003] At present, the wind energy cables manufactured are made of EPDM rubber, which is a terpolymer of ethylene, propylene and non-conjugated diene, which has excellent insulation, temperature resistance range, oxidation resistance and strong At the same time, because it belongs to the polyolefin family, it has excellent vulcanization characteristics. It is often added with a large amount of fillers to reduce costs. However, it is often elastic, flame retardant, wear-resistant, ozone erosion-resistant, Weather resistance and other properties are still not good enough
