Description

technical field [0001] The invention relates to the technical field of nitrile rubber materials, in particular to a high-strength weather-resistant modified nitrile rubber material and a preparation method thereof. Background technique [0002] In recent years, due to the shortage of resources such as oil and coal at home and abroad, countries have vigorously developed new energy sources. Wind energy, as a clean energy source, is energy-saving and environmentally friendly, and has an inexhaustible source. However, the cable accessories for wind power generation cannot keep up with the requirements of wind power generation. Due to difficult maintenance and harsh service conditions, the cables for wind power generation have high requirements for cable performance and life, and the cables are constantly twisted during operation. At present, natural rubber and styrene-butadiene rubber are mostly used for cable sheath rubber. This kind of cable sheath rubber has good elasticity, ...
