Description

technical field [0001] The invention relates to the technical field of cable sheaths, in particular to an environmentally friendly modified natural rubber material for cable insulation layers. Background technique [0002] my country's natural rubber resources are very rich, with high elasticity, excellent electrical insulation properties, good wear resistance and drought resistance. my country's resources are relatively scarce, and the rational use of natural rubber to alleviate the shortage of resources in our country is extremely important for economic development and environmental protection. effect. At present, the performance of natural rubber reinforced wire and cable insulation layer is developing more and more rapidly, which has great economic potential, but natural rubber is easy to age, and the mechanical properties cannot meet the requirements, and the prepared waste wire and cable insulation layer is easy to pollute the environment after being buried. At present...
