Problems solved by technology

[0002] Cable sheaths are widely used in the cable manufacturing process. They are often used to wrap single-strand or multi-strand wires and insulating layers. Now the composite performance of decoration materials is getting better and better. Although the appearance is beautiful, it will emit peculiar smell when heated, especially when encountering In the event of a fire, it is easier to burn and emit poisonous gas; the death rate due to suffocation due to poisonous gas in fires in my country currently accounts for more than 80%
However, the traditional cable sheath is flammable, toxic and dense in smoke due to the addition of too much PVC.

Abstract

The invention discloses a low-smoke and non toxicity cable sheath, and belongs to the technical field of cable lines. The low-smoke and non toxicity cable sheath is formed by carrying out a reaction on the following raw materials by weight: 40-50 parts of a suspension method polyvinyl chloride resin, 25-30 parts of a plasticizer, 2-4 parts of a composite stabilizing agent, 1-2 parts of an anti-oxidant, 50-60 parts of a filler and 0.1-1 part of a lubricant, wherein the filler is calcining ceramic clay and / or calcium carbonate, and the plasticizer is diisodecyl ortho-phthalate or diisononyl phthalate. According to the low-smoke and non toxicity cable sheath, combination of various raw materials can greatly reduce the usage of the suspension method polyvinyl chloride resin, combustion is difficult, the smoke is low even in a combustion process, poison gas is greatly reduced, basically, no toxin is generated, and the low-smoke and non toxicity cable sheath is suitable for popularization and application in public area, and has the advantage of environmental protection and is beneficial to health.
