Abstract

The invention discloses a low-toxicity, high-fire-retardant, and uvioresistant cable sheath. The cable sheath comprises the following raw materials in parts by weight: 30-40 parts of chlorosulfonated polyethylene, 5-15 parts of semi-reinforced carbon black, 0.2-0.3 part of an anti-aging agent, 0.4-0.6 part of stearic acid, 0.4-0.6 part of paraffin, 0.5-1.5 parts of transformer oil, 0.5-1.5 parts of epoxidized soybean oil, 3-4 parts of chlorinated paraffin with the concentration of 52%, 1.5-2.5 parts of a plasticizer, 2-3 parts of antimony trioxide, 4-6 parts of light calcium carbonate, 4-6 parts of pottery clay powder, 4-6 parts of aluminium hydroxide, 1.5-3.0 parts of magnesium oxide, 0.6-0.9 part of a vulcanizing agent and 0.1-0.3 part of a silane coupling agent. Besides, the invention provides a method for preparing the sheath. The cable sheath has the benefit that the sheath has the properties of being low in toxicity, high in flame retardance, and excellent in anti-ultraviolet aging.

Description

technical field [0001] The invention belongs to the technical field of electric wires and cables, and in particular relates to a low-toxic, high-flame-retardant and anti-ultraviolet sheath for cables and a preparation method thereof. Background technique [0002] The cable sheath is usually used in conjunction with the cable, and the quality of the cable sheath directly affects the service life of the entire cable. At present, although there are many styles of cable sheaths on the market, traditional cable sheaths usually have the following disadvantages: [0003] 1. The function is single, and the protective effect on the cable is limited; [0004] 2. Although some cable sheaths have high flame-retardant performance characteristics, there is a certain waste of raw materials in the production process; [0005] 3. Some cable sheaths on the market are highly toxic and do not have the function of anti-ultraviolet rays. [0006] How to prepare a cable sheath with low toxicity...
