A flame-retardant, oil-resistant and aging-resistant thermoplastic elastomer cable material

Abstract

The invention provides a flame-retardant oil-resistant aging-resistant thermoplastic elastomer cable material prepared from the following raw materials in parts by weight: 100 parts of polyvinyl chloride SG-3, 10-20 parts of nitrile rubber N26, 10-15 parts of polycarbonate, 10-15 parts of poly(ethylene terephthalateco-1,4-cylclohexylenedimethylene terephthalate), 15-20 parts of a silane coupling agent, 30-40 parts of bisphenol-A bis(diphenyl phosphate), 20-30 parts of calcium carbonate, 1-2 parts of calcium silicate, 30-50 parts of barium stearate, 10-15 parts of cresyl diphenyl phosphate, 3-4 parts of glycerol trioleate, 2-3 parts of a crosslinking agent TAIC, 2-3 parts of stearic acid, 1-2 parts of N,N'-m-phenylenedimaleimide, 5-8 parts of alcohol ester-12, 0.5-1.0 part of PE wax, 1-2 parts of aluminum nitride powder, 1-2 parts of jade powder, and 8-10 parts of a modified filler. The flame-retardant oil-resistant aging-resistant thermoplastic elastomer cable material has the characteristics of flame retardancy, oil resistance, aging resistance, and acid and alkali resistance, and has lower specific density and low manufacture cost.

Description

technical field [0001] The invention relates to the field of cable materials, in particular to a flame-retardant, oil-resistant, aging-resistant thermoplastic elastomer cable material and a preparation method thereof. Background technique [0002] With the rapid development of the global economy and the enhancement of human awareness of environmental protection, the requirements for the quality and performance of wires and cables in various fields are getting higher and higher, and there are more and more fires caused by the aging of wires and cables. How to reduce the fire Low smoke, halogen-free, flame retardant, and environmental protection have also become the development direction of the wire and cable industry. Among them, the demand for halogen-free low-smoke flame-retardant cable materials is increasing. At present, most of the production of halogen-free low-smoke flame-retardant cable materials is to add a large amount of magnesium hydroxide or magnesium hydroxide t...

Problems solved by technology

Among them, the demand for halogen-free low-smoke flame-retardant cable materials is increasing. At present, most of the production of halogen-free low-smoke flame-retardant cable materials is to add a large amount of magnesium hydroxide or magnesium hydroxide to polyolefin substrates to achieve flame retardancy. However, the addition of a large amount of inorganic materials affects the physical and mechanical properties and processing performance of the cable material. Its softness, poor weather resistance, oil resistance, and low temperature resistance at room temperature are not very good.
