Problems solved by technology

[0003] At present, the wear resistance of the cable sheath material is poor, so when the cable is laid on the ground, it is easily damaged by people's stepping on it, and even the internal wires are exposed, which is prone to the risk of electric shock and has low safety.

Abstract

The invention provides a strong-efficient wear-resistant cable sheath and a preparation method thereof, and relates to the technical field of the cable production. The cable sheath is prepared by the following raw materials in parts by weight: 40-50 parts of butadiene rubber, 15-20 parts of isoprene rubber, 10-15 parts of ethylene propylene rubber, 8-12 parts of vulcanized neopentyl glycol dioleate, 1-2 parts of a modifier, 6-8 parts of dibenzyl disulfide, 3-5 parts of 2,5-dimercaptothiazole, 5-7 parts of thiophosphate isobutylene, 2-4 parts of potassium metaborate, 4-6 parts of zinc thiocarbonate, 2-4 parts of iron sulfide, 3-5 parts of molybdenum nitride, 2-4 parts of a dispersant, and 2-4 parts of a vulcanizing agent. The strong-efficient wear-resistant cable sheath is capable of overcoming deficiency of the prior art, effectively improving a wear-resistant property of the cable sheath, preventing the cable from being damaged by trampling of people, and even causing an electric shock risk because an internal lead is exposed. The cable sheath is excellent in whole performance, high in safety, long in service life, and suitable for popularization.

Description

technical field [0001] The invention relates to the technical field of cable production, in particular to a strong wear-resistant cable sheath and a preparation method thereof. Background technique [0002] The cable is usually a rope-like cable twisted by several or several groups of wires (at least two in each group). Each group of wires is insulated from each other and is often twisted around a center. An insulating covering used to connect electrical circuits, appliances, etc. The cable has the characteristics of internal electrification and external insulation. The outer covering of the cable conductor is the cable sheath, which is used to protect the inner conductor and prevent the user from getting an electric shock. [0003] At present, the wear resistance of the cable sheath material is poor, so when the cable is laid on the ground, it is very easy to be damaged by people's stepping on it, and even the internal wires are exposed, which is prone to the risk of elec...
