Problems solved by technology

At present, natural rubber and styrene-butadiene rubber are mostly used for cable sheath rubber. This kind of cable sheath rubber has good elasticity, but its weather resistance is poor. It is easy to age and crack during actual use, and its torsion resistance cannot meet the demand.
[0003] In summary, there is currently a lack of a salt-corrosion-resistant torsion-resistant control cable for offshore wind power and a preparation method thereof in the field

Abstract

The invention relates to the technical field of cable materials, in particular to a salt-corrosion-resistant torsion-resistant control cable for ocean wind power and a preparation method of the salt-corrosion-resistant torsion-resistant control cable. The cable is composed of an ethylene copolymer, maleic anhydride grafted EVA, magnesium oxide, a reinforcing agent, a silane coupling agent, a lubricant, a flame retardant and modified potassium hexatitanate whiskers. The cable provided by the invention has relatively good performances in the aspects of thermal aging resistance, salt spray corrosion resistance, seawater corrosion resistance and the like, and can well adapt to a complex climate environment where an ocean wind power facility is located. The cable has excellent torsion resistance, the number of times of torsion resistance is higher than 2500, and torsion at normal temperature or low temperature has no obvious influence on the material of the cable.

Description

technical field [0001] The invention relates to the technical field of cable materials, in particular to a salt-corrosion and torsion-resistant control cable for marine wind power and a preparation method thereof. Background technique [0002] At present, offshore wind energy resources are abundant, and my country's usable sea area is more than 3 million square kilometers. It is one of the countries with the most abundant wind energy resources in Shanghai in the world. The preliminary estimate of the wind energy resources that can be developed and utilized is about 1 billion kW, of which, offshore The wind energy reserves that can be developed and utilized are about 750 million kW. With the development of the wind power market, the installed capacity of wind turbines is increasing year by year, and the demand for wind power cables matching them will increase. However, the cable accessories for wind power generation cannot keep up with the requirements of wind power generatio...
