Problems solved by technology

The feature of the halogen-free low-smoke flame-retardant cable is that it not only has good flame-retardant properties, but also does not contain halogen, which is less corrosive and toxic when burned, and produces a very small amount of smoke, thereby reducing Damage to people, instruments, and equipment is conducive to timely rescue in case of fire. Although it has good flame retardancy, corrosion resistance, and very little smoke concentration, its mechanical and electrical properties are slightly worse than ordinary cables.

Abstract

The invention relates to a flame-retardant cable and wire material. The material comprises components by mass as follows: 6-10 parts of triotyl trimellitate, 15-30 parts of tetramethylpiperidinooxy, 8-16 parts of benzoyl peroxide, 10-25 parts of rutile titanium dioxide, 8-10 parts of dioctyl phthalate, 4-10 parts of dicetyl peroxydicarbonate, 12-20 parts of triphenyl phosphate, 0.5-1 part of ultra-fine acrylate rubber powder, 0.1-0.5 parts of an acrylonitrile-butadiene-styrene copolymer, 5-15 parts of di-isononyl-cyclohexane-1,2-dicarboxylate and 1-3 parts of zinc oxide. The flame-retardant cable and wire material has the advantages of soft texture, wear resistance, high-temperature resistance, safety, reliability and good radiation performance, cables and wires can be used in a very severe environment, and the material has higher weather resistance, deformation resistance, high tensile strength, large elongation, high adaption to shrinking, cracking and deformation of a base layer, excellent acid resistance, excellent alkali resistance and excellent flame retardancy and can be used conveniently as required.

Description

technical field [0001] The invention relates to the technical field of cables, in particular to a flame-retardant cable wire material. Background technique [0002] Flame-retardant cable refers to the cable that the sample is burned under the specified test conditions. After the test fire source is removed, the spread of the flame is only within a limited range, and the residual flame or residual flame can extinguish itself within a limited time. The fundamental characteristic is: it may be burned out and cannot operate in case of fire, but it can prevent the spread of fire. In layman's terms, in the event of a wire fire, it can limit the combustion to a local area without spreading, keep other various equipment, and avoid greater losses. [0003] Under the specified test conditions, the sample is burned, and after the fire source is removed, the spread of the flame on the sample is only within a limited range and the characteristics of self-extinguishing, that is, the abil...
