Abstract

The invention relates to a rubber sheath material for a cable. The formula of the rubber sheath material comprises the following components in parts by weight: 100 parts of chlorinated polyethylene, 20-80 parts of bentonite, 20-40 parts of plasticizing agent, 2.5-5 parts of vulcanizing agent, 1.5-6 parts of vulcanizing additive, 1.0-10 parts of activating agent, 0.2-3 parts of anti-aging agent and 0.5-1.5 parts of coupling agent. The rubber sheath material has the advantages that the formula is low in cost and simple in component; all the components have respectively-independent actions and advantages, and are also matched mutually to form a complete body; in the milling and weighing process with more steps, the production efficiency can not be reduced, once the batching generates problems, the inspection is very convenient; sulfur is not added in the material, so that the problem that oxidation and blackening of copper caused by mobility of sulfur are caused to accelerate the ageing of an insulating layer and cause the problem of larger potential hazards of the cable in use is avoided, so that the safety coefficient is improved; and a product prepared by the formula is excellent in performance.

Description

technical field [0001] The invention relates to a material for cables, more specifically, the invention relates to a rubber sheath material for cables, which belongs to the technical field of cable sheath materials. Background technique [0002] Rubber is commonly used in the cable industry due to its good softness and high elasticity. When rubber is used as a sheath material, it is usually required to have good mechanical properties to protect the insulation or even the entire cable. Especially in harsh environments, such as mines, blasting sites, etc., the cable sheath is particularly required to have high tensile strength and tear resistance. Chlorinated polyethylene (CPE for short) is often used as a sheath material in the wire and cable industry. Common CPE sheaths are black and colored. But no matter what color CPE is, it must be added with a reinforcing agent and vulcanized before it can be used. Among them, the black CPE sheath uses carbon black as a reinforcing a...
