Abstract

The invention relates to an environmentally-friendly low-smoke zero-halogen flame-retardant TPEE polyester elastomer cable material and a preparation method thereof. The raw materials used herein comprise 100 weight portions of TPEE polyester elastomer, 10-30 weight portions of polyolefin elastomer, 20-60 weight portions of flame retardant, 10-20 weight portions of flame-retardant synergistic agent, 1.0-1.8 weight portions of lubricant, 0.45-0.6 weight portions of antioxidant, and 1-8 weight portions of other auxiliary agents. The preparation method comprises the following steps: firstly standing the flame-retardant synergistic agent for some time, then weighing the raw materials and putting the raw materials in a mixer for uniformly mixing, and then carrying out granulation by an extruder. Compared with the prior art, the cable material has good mechanical properties, good high / low temperature resistance and aging resistance, and strong oil resistance, and can be used for producing cables for locomotives and ships.

Description

technical field [0001] The invention relates to an elastomer cable material and a preparation method thereof, in particular to an environment-friendly low-smoke halogen-free flame-retardant TPEE polyester elastomer cable material and a preparation method. The compound has good flame retardancy and oil resistance, and is especially suitable for wire and cable, ships, rail transit and other fields. Background technique [0002] Thermoplastic polyester elastomer (TPEE) is an engineering elastomer with excellent comprehensive properties. Because thermoplastic polyester elastomer has both the excellent elasticity of rubber and the ease of processing, impact resistance, oil resistance and chemical solvent resistance of thermoplastics. Sex and other advantages. With the continuous expansion of the application field of TPEE, the requirements for other special functions are getting higher and higher, especially in the fields of automotive electrical systems, railways, wires and cabl...
