Abstract

The invention discloses a polyphenylether cable compound for adjusting hardness and a preparation method. The compound comprises the following ingredients in part by weight: 20 to 30 parts by weight of polyphenylether resin (PPE), 20 to 40 parts by weight of elastomer, 10 to 20 parts by weight of polyolefine, 20 to 35 parts by weight of flame retardant agent, 20 to 60 parts by weight of plasticizer, 5 to 15 parts by weight of inorganic filler, 0.1 to 0.3 part by weight of lubricant and 0.1 to 1.0 part by weight of antioxidant. Due to the adoption of the method, the hardness of the PPE cable compound can be effectively adjusted, and an economical and feasible technique can be provided to prepare the PPE cable compound with smooth appearance, good hand touch feeling, excellent mechanical property, high flame retardant property and high elasticity.

Description

technical field [0001] The invention relates to a polyphenylene ether (PPE) cable compound, in particular to a method for adjusting the hardness of the PPE cable compound, and belongs to the field of high polymer processing and modification. Background technique [0002] With the continuous development of science and technology, wires and cables are widely used in energy transmission and information transmission, covering various fields of industry, agriculture, and daily life. Due to the enhancement of environmental awareness around the world, halogen-free flame-retardant wires and cables have gradually become the development trend of the wire and cable industry. [0003] Polyphenylene ether (PPE) resin has excellent physical and mechanical properties, electrical insulation and heat resistance. In addition, polyphenylene ether is very suitable for the manufacture of halogen-free Environmentally friendly flame retardant wire and cable materials. However, the high melt visc...
