Description

technical field [0001] The invention relates to the technical field of cable sheaths, in particular to a heat-oxidative aging-resistant modified chlorinated polyethylene cable sheath material. Background technique [0002] Chlorinated polyethylene is a chlorine-containing polymer obtained after chlorination of polyethylene. It not only has good mechanical properties, such as tearing, wear resistance, bending resistance, etc., but also has good heat and oxygen aging resistance, Weather resistance, ozone resistance, oil resistance, flame retardancy, corona resistance, processing performance, high filling performance, can be used with many rubbers and fillers to improve its performance. [0003] The cable sheath is the outermost layer of the cable. As a cable sheath material, it should have excellent mechanical properties, aging resistance, corrosion resistance, flame retardancy, oil resistance, impact resistance, etc. Chlorinated polyethylene can be used as a cable sheath mat...
