Problems solved by technology
Conventional PVC sheathed wires and cables have quite serious pollution—a large amount of harmful substances such as dioxin, hydrochloric acid, and lead are produced during manufacture, use, and disposal.
When the PVC sheath material burns, it will produce a lot of smoke and produce harmful HCL gas; and most PVC sheath materials contain Pb (lead), Cd (cadmium) and other harmful substances (used as cable stabilizers). Heavy metals will cause certain harm to human health; after incineration or burial, they will cause pollution to soil and water sources

Abstract
The invention discloses a polyvinyl chloride (PVC) cable sheath material and a preparation method thereof. The PVC cable sheath material comprises 100 parts of PVC resin, 30-50 parts of plasticizer, 3-7 parts of compound stabilizer, 20-40 parts of active calcium carbonate, 5-15 parts of kaolin, 5-15 parts of aluminum hydroxide, 3-6 parts of antimony trioxide, 3-5 parts of zinc borate and 0.5-1.5 parts of aromatizer. In the cable sheath rubber disclosed by the invention, through the optimal combination of aluminum hydroxide, antimony trioxide and zinc borate, the carbonization amount is improved by approximate 50%; the smoke generation amount during naked flame combustion is reduced by 30-50%, and the limiting oxygen index (LOI) is improved to 33; by selecting a proper plasticizer, the material has excellent low-temperature and high-temperature resistance at the same time, and the use temperature of the material is (-30)-90 DEG C; and a mint-flavored essential oil aromatizer is added to the material, so that the obtained product has aromatic odor and has the actions of eliminating nausea, nervousness and tension headache and dispelling mosquito.
Description
[0001] [0002] technical field [0003] The invention relates to the field of polymer materials for power cables, in particular to a PVC sheath material and a preparation method thereof, which achieve environmental protection, flame retardancy, non-drip ignition, and superior low / high temperature resistance through optimization of each component. It has an aromatic smell and can be used to prepare wire and cable sheaths, especially for the production of environmentally friendly wire and cable products matched with household appliances. Background technique [0004] Numerous fire reports have identified the deaths as the result of smoke and toxic fumes from burning plastic. Especially for high-rise buildings, the situation is more obvious. According to statistics, 80% of the fatal accidents in fires are caused by suffocation of smoke and toxic gases. In addition, the smoke greatly reduces the visibility of the fire scene, delaying the time for extinguishing the fire and sav...
