Abstract

The invention discloses a method for preparing an elastomer sheath material for a wind energy cable, belonging to the technical field of high polymer materials. The method comprises the following steps: adding water and an emulsifier into a reactor and uniformly stirring; adding methacrylic acid and hydroxyethyl acrylate, adding zirconia powder and calcium carbonate powder, and uniformly stirring; adding an initiator, heating to carry out a polymerization reaction, and performing suction filtration to obtain a polymer; washing the filter cake by using ethanol and drying the filter cake, thereby obtaining a prepolymer; uniformly mixing the prepolymer, a styrene-butadiene copolymer, polyoxyethylene, a styrene-ethylene-butylene-styrene block copolymer SEBS, white oil, diol dimethacrylate, an antioxidant, a silane coupling agent and a lubricating agent, feeding in a double-screw extruder for extrusion granulating, drying the granules in a hot air drier, thereby obtaining the material. The sheath material prepared by the invention has good tensile property and corrosion resistance.

Description

technical field [0001] The invention discloses a preparation method of an elastic sheath material for wind energy cables, belonging to the technical field of polymer materials. Background technique [0002] With the reduction of mineral energy such as coal and oil in the world, and the enhancement of human environmental protection awareness, people are actively exploring the use of renewable energy to achieve sustainable development of society. Among the many new energy sources, wind power generation is the fastest-growing, most economical, green and environmentally friendly new energy source. As a new energy source, wind power has been developing rapidly all over the world in recent years, and at the same time, it is favored by people. Wind power cables are mainly used for connecting wires of fans, and the use environment is very harsh. They must not only have excellent electrical properties and torsion resistance, but also have excellent wear resistance, cold resist...
