Technical Field

The invention belongs to the technical field of materials, and particularly relates to an oil-resistant wear-resistant pulley material and a preparation method thereof.

Background

Most of the prior pulley materials used for the cables and the cables are rubber or plastic, and the materials have poor oil resistance and wear resistance and are easy to expand and deform, so the problems of the oil resistance and the wear resistance of the pulley materials used for the cables and the cables have a great proportion in the material loss prevention treatment problem. In the use of a cable or a wire and the operation of a machine in a factory, the pulley material is expanded and deformed by oil or the pulley is worn. Poor handling can significantly reduce the useful life of the sheave material. Most of the currently used pulley materials are single materials and do not have oil-resistant and wear-resistant effects. The oil-resistant and wear-resistant pulley material has two effects of oil resistance and wear resistance, the service life of the pulley can be effectively prolonged, and the cost is saved. The oil-resistant and wear-resistant pulley material is nontoxic and harmless, has good effect and makes a great contribution to the aspect of pulley materials.
