A halogen-free flame retardant polyphenylene ether cable material

Abstract

The invention provides a halogen-free flame-retardant polyphenylether cable material prepared from the following raw materials in parts by weight: 40-50 parts of polyphenylether, 10-15 parts of a POE elastomer, 10-12 parts of polypropylene, 10-15 parts of molybdenum trioxide, 8-10 parts of ammonium molybdate, 0.2-1 part of an antioxidant 1010, 10-15 parts of epoxidized soybean oil, 5-7 parts of glycerol, 0.2-1 part of nano silicon carbide, 1-2 parts of ammonium polyphosphate, 1-2 parts of 4-methyl guaiacol, 1.0-3.0 parts of PE wax, 1-2 parts of acetylacetone selenium, and 10-15 parts of a modified filler. The cable material is low in production cost, has good processability, non halogen, flame retardancy, high tensile strength and other excellent performance, and can be widely applied in electronic wire insulation materials.

Description

technical field [0001] The invention relates to the field of cable materials, in particular to a halogen-free flame-retardant polyphenylene ether cable material. 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 aluminum hydroxide to polyolefin substrates to achieve flame retardancy.

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 aluminum 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.
