Problems solved by technology

[0002] There are many types of materials that can be used for cable sheathing today. Each material has different characteristics and performance. In order to achieve a better integration of the advantages of various materials, materials with different characteristics are combined to complement each other. Constitute a composite material, it can not only retain the advantages of the original component materials, but also obtain the performance that the original components do not have through the composite effect, so that the cable sheath material has new superior properties, cotton fiber is rich in cellulose, used to supplement The strong rubber composite material has excellent physical and mechanical properties, and the product is easy to process and light in weight. However, after the cotton fiber is added to the rubber molecule, the force between the rubber molecule and the rubber molecule is weak, and it is easy to cause stress concentration when the force is applied to the composite material. How to prepare a cable sheath material with good bonding, excellent mechanical properties of the composite material, and uniform dispersion in the rubber matrix has become a technical problem to be solved at present
