Abstract

The invention discloses a high-elasticity high-strength weather-resistant flame-retardant ethylene propylene diene monomer cable material which is prepared from the following raw materials in parts by weight: 48-54 parts of ethylene propylene diene monomer rubber, 28-34 parts of preformed fluorine-containing polymer, 20-23 parts of styrene-butadiene rubber, 10-12 parts of hard clay, 3-5 parts of monoalkoxy titanate coupling agent, 5-8 parts of aluminum hydroxide, 6-7 parts of red phosphorus master batch, 4-5 parts of antimony trioxide, 0.5-0.8 part of sulfur, 0.4-0.6 part of dicumyl peroxide, 1.1-1.4 parts of N-cyclohexyl-2-benzothiazole sulfenamide, 1.4-1.5 parts of trimethylolpropane trimethylacrylate, 1.6-2 parts of anti-aging agent H and 1.2-1.5 parts of anti-aging agent DFC-34. The invention also discloses a preparation method of the high-elasticity high-strength weather-resistant flame-retardant ethylene propylene diene monomer cable material. The high-elasticity high-strength weather-resistant flame-retardant ethylene propylene diene monomer cable material has the advantages of high elasticity, high strength, excellent flame retardancy, excellent wear resistance, excellent ozone erosion resistance and excellent weather resistance.

Description

technical field [0001] The invention relates to the technical field of EPDM rubber materials, in particular to a highly elastic, high-strength, weather-resistant and flame-retardant EPDM cable material and a preparation method thereof. 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 ...

AI Technical Summary

Problems solved by technology

[0003] The currently manufactured wind energy cables use EPDM rubber, which has excellent insulation, temperature range resistance, oxidation resistance and strong corrosion resistance. At the same time, because it belongs to the polyolefin family, it has excellent vulcanization properties. A large amount of fillers are often added to reduce costs, but in actual use, the properties of elasticity, flame retardancy, wear resistance, ozone erosion resistance, and weather resistance are still not good enough
