Problems solved by technology

[0002] With the rapid development of the industrial field, traditional rubber materials can no longer meet the design and use requirements of contemporary cable sheath materials. At present, glass fibers are often used to reinforce cable sheath materials, which have low cost, moderate strength, heat resistance and flex resistance. It has better performance and has been widely used for many years to solve various problems, but the use of these materials will cause serious environmental problems. Natural fiber composite rubber materials are a new direction in the field of cable sheathing. In fact, most plant fiber composite materials Low performance, poor stress bearing capacity, poor thermal stability, how to prepare a cable sheath material with strong stress bearing capacity, good thermal stability, environmental protection and low cost has become a technical problem to be solved at present
