Problems solved by technology

[0002] During the long-term work of thermocouple compensation cable, it is easy to accumulate heat and cause a fire. The main factor causing death in a fire is not the direct combustion of the flame, but the smoke generated when the material is burned. These smoke not only produce a large amount of toxic substances , and can lead to suffocation, which is the main factor of death due to fire, and most of the existing power cable materials will produce a lot of smoke and toxic substances when burned

Abstract

The invention discloses a sheathing material for a thermocouple compensating cable. The sheathing material is prepared from the following raw materials in parts by weight: polyvinyl chloride, vinyl chloride-vinyl acetate copolymer, ethylene-propylene-dicyclopentadiene polymer, modified opal, modified fiberglass, triallyl cyanurate, calcium trifluoromethanesulfonate, polyoxyethyl glyceryl ether, azodicarbonamide, 1-ethyl-2-pyrrolidone, nano magnesium oxide, zinc stearate, magnesium hydrate, lignocellulose, butylated hydroxytoluene, vinyl trimethoxy silane, sodium laurylsulfate, diethyl phthalimidomalonate, carbon black, diatomite and attapulgite. The sheathing material disclosed by the invention has high and low temperature resistance and good flame retardancy, and also has higher tensile strength, higher impact strength, better water resistance, better corrosion resistance, creep resistance and wearing resistance at the same time; the effects of flame retardancy and heat insulation can be further enhanced by the modified opal and the modified fiberglass which are added.
