Cable sheath material having cracking resistance and good thermal stability and used for wind power generation

Abstract

The invention a cable sheath material having cracking resistance and good thermal stability and used for wind power generation. The cable sheath material is prepared from raw materials in parts by weight as follows: 10-30 parts of phenyl siloxane rubber, 10-20 parts of nitrile rubber, 35-65 parts of styrene butadiene rubber, 1-2 parts of N,N'-m-phenylene dimaleimide, 1-2 parts of sodium ammonium dichromate, 2-4 parts of dicumyl peroxide, 10-15 parts of white carbon black, 45-65 parts of heavy calcium carbonate, 15-25 parts of bentonite, 15-23 parts of barite, 2-4 parts of palm wax, 2-5 parts of trioctyl phosphate, 1.5-2.5 parts of microcrystalline wax, 1.5-3 parts of dibutyl phthalate, 1-1.8 parts of epoxidized soybean oil, 1-2 parts of stearic acid and 2-4 parts of an antioxidant AT-215. The cable sheath material has good thermal stability and excellent mechanical properties and is aging-resistant.

Description

technical field [0001] The invention relates to the technical field of cables, in particular to a cable sheath material for wind power generation with good crack resistance and thermal stability. Background technique [0002] Judging from the growth of global wind power generation in the past two years, wind turbine generators may grow at a rate of more than 50% in the next few years. These conditions show that there is a space for vigorous development and promotion of wind power generation, and it is matched with wind power projects. There is a huge market demand for special cable sheathing materials used. Wind power generation projects are carried out in the open air, and the service life of the cable sheath material is required to be very long. This requires extremely high thermal stability, aging resistance and mechanical properties of the cable material for wind turbine generators in extreme environments. Ordinary The cable has poor crack resistance, low safety perform...
