High-elasticity and high-strength weather-resistant and flame-retardant cable material for wind power generation

Abstract

The invention discloses a high-elasticity and high-strength weather-resistant and flame-retardant cable material for wind power generation. The cable material comprises the following raw materials in parts by weight: 35-60 parts of ethylene propylene diene monomer rubber, 20-30 parts of fluorine-containing polymer, 20-25 parts of styrene-butadiene rubber, 6-19 parts of hard clay, 2-6 parts of a monoalkoxy titanate coupling agent, 5-10 parts of aluminum hydroxide, 4-6 parts of red phosphor masterbatch, 3-4 parts of antimony trioxide, 0.3-0.6 parts of sulfur, 0.3-0.6 parts of dicumyl peroxide, 1.5-1.8 parts of N-cyclohexyl-2-benzothiazole sulfenamide, 1.2-1.3 parts of trimethylolpropane trimethacrylate, 1.1-1.5 parts of an antioxidant H, 1.1-1.5 parts of an antioxidant DFC-34, 6-10 parts of zinc oxide, 2-5 parts of melamine cyanurate and 3-6 parts of epoxidized soybean oil. The cable material provided by the invention has high elasticity, high strength, and excellent flame retardancy, wear resistance, ozone erosion resistance and weather resistance.

Description

technical field [0001] The invention relates to the technical field of rubber materials, in particular to a high-elasticity, high-strength, weather-resistant and flame-retardant cable material for wind power generation. 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...

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
