Abstract

The invention discloses a high-flame-retarding low-smoke modified polyvinyl ethylene cable material, which is characterized by being prepared from following raw materials, by weight, 100-120 parts of polyvinyl ethylene resin, 8-12 parts of ethyleneglycol polyadipate glycol, 3-6 parts of antimonous oxide, 4-5 parts of paraffin chloride, 8-10 parts of aluminum hydroxide, 30-40 parts of dioctyl terephthalate, 10-14 parts of trimethylbenzene phosphate, 5-7 parts of an organic tin stabilizing agent, 4-8 parts of an anti-oxygen agent TPP, 6-9 parts of nano kaolin, 7-10 parts of epoxy soybean oil, 9-13 parts of tetrabromophthalate, 7-8 parts of an ultraviolet absorbent, 4-5 parts of pentaerythritol ammonium stearate, 5-6 parts of white oil, 6-8 parts of mica powder, 7-9 parts of calcium ricinoleate, 5-9 parts of electric-conductive carbon black and 10-12 parts of nano silicon dioxide. In the invention, by means of a synergistic effect between the added antimonous oxide and the paraffin chloride, polyvinyl ethylene is enhanced in flame retarding performance. The added trimethylbenzene phosphate has an effect as a condensed phase and the added plasticizer, the dioctyl terephthalate, can improve toughness of the cable, and the added other filling materials can improve the physical and chemical performances of the cable, thereby ensuring a stable mechanical performance and also achieving an effect of inhibiting smoke.

Description

Technical field [0001] The invention relates to a cable material, in particular to a high flame retardant and low smoke modified polyvinyl chloride cable material and a preparation method thereof. Background technique [0002] In modern factories and commercial buildings, in order to maintain normal operations, it is necessary to use a large variety of cables to provide power, lighting, information, and data transmission cables. Most of these cables are laid in bundles in the form of tunnels, trenches, shafts and suspensions. The arc caused by the cable's own fault and the fire nearby can easily cause the cable fire. After the cable catches fire, the fire burns along the cable. Because most of the cables are laid in bundles in tunnels, trenches, and shafts, most of them are limited and relatively closed spaces, which makes it difficult for the heat released by combustion to dissipate. After a fire, the heat accumulates quickly, making the temperature The sharp rise caused the f...
