Description

technical field [0001] The invention relates to the technical field of cable sheaths, in particular to a heat-resistant, wear-resistant and tear-resistant cable sheath. Background technique [0002] With the rapid development of the cable industry, the traditional rubber sheath materials for cables can no longer meet the requirements of use. The outermost layer of wires and cables is often provided with a cable sheath to isolate external water, corrosive materials, and friction from damage to the cable. Protection for cables. Due to its high temperature resistance, chemical corrosion resistance and low cost, phenolic resin is widely used in many fields such as cables, automobiles, transportation, military, etc., especially in the field of cables. The urgent demand for fuel materials has led to the rapid development of various modified phenolic resins. However, its heat resistance, wear resistance and tear resistance are still not excellent enough. How to strengthen these w...
