Problems solved by technology

Although there are many kinds of cables on the market, the performance of the sheath material of most cables is still not very ideal. During the use of the cable, there are defects such as unsatisfactory heat resistance, low strength, and poor flame retardancy. It shortens the service life of the cable, increases the cost of use, brings a lot of inconvenience to the actual use, and even threatens the safety of people's lives and property. Therefore, it needs to be improved

Abstract

The invention discloses a novel flame-retardant sheathing film for cables. The novel flame-retardant sheathing film contains the following materials in parts by weight: 100 parts of PVC (Polyvinyl Chloride) powder with high K value, 40-60 parts of TOTM (Trioctyl Trimellitate) plasticizing agent, 1-2 parts of barium-zinc type heat stabilizer, 50-70 parts of nanoscale expanding type vermiculite powder, 0.5-1 part of stearic-acid type lubricant, 3-5 parts of antimony-trioxide flame retardant, 5 parts of color-mixing pigment and 5-20 parts of inorganic-powder filler. The novel flame-retardant sheathing film disclosed by the invention has better tensile strength, tearing strength and elongation and has good flame-retarding effect; the high temperature can be resisted, under the high-temperaturecondition, the surface is not easily scalded, the color fastness is good, the ageing is difficult, the corrosion resistance is good and the surface color degree is bright and smooth.

Description

technical field [0001] The invention relates to the field of cable materials, in particular to a novel flame-retardant cable sheath film and a preparation method thereof. Background technique [0002] With the development of my country's petrochemical, communication, transportation, construction, electric power and other industries, the demand for cables in power plants, substations, smelting and petrochemical industries has been extremely high in recent years, and at the same time higher requirements have been put forward for the performance and quantity of cables. Therefore, the materials used to make cables are gradually high-grade, specialized and specialized. The cable is composed of an electric wire and a covering layer (sheath layer) provided on the outer periphery of the electric wire. At present, the coating layer (sheath layer) is arranged on the outermost periphery of the cable, and is formed of an electrically insulating material mainly made of rubber or resin. ...
