Abstract

Provided are halogen-free flame-retardant high-temperature-resistant polyester elastomers and a preparation method therefor. The provided polyester elastomers comprise the following raw materials, by weight, 20-50 parts of polyester elastomers, 10-30 parts of polybutylene terephthalate, 2-10 parts of compatilizer, 10-30 parts of phosphor-nitrogen flame retardant, 5-20 parts of phosphonate flame retardant, 2-5 parts of acid absorbing agent, 3-8 parts of flame retardation synergistic agent, 0.3-0.8 part of anti-oxidant and 0.5-2 parts of anti-hydrolysis agent. The preparation method is as follows: polyester elastomers and polybutylene terephthalate are subjected to drying processing, and are mixed with other ingredients uniformly in a high-speed mixing machine; discharging is carried out, the mixture is subjected to bar drawing and granulation by a double screw extruder, and halogen-free flame-retardant high-temperature-resistant polyester elastomers are prepared. The defects of the prior art are overcome, on the premise that present device configuration and technological parameter setting are not changed, an optimal solution is provided that halogen-free flame-retardant high-temperature-resistant polyester elastomers can be produced stably, the high temperature resistance of the material is improved obviously, the flame resistance is raised greatly, and other performances are optimized.

Description

technical field [0001] The invention relates to the field of polymer elastomer materials, in particular to a halogen-free flame-retardant and high-temperature-resistant polyester elastomer and a preparation method thereof. The halogen-free flame-retardant and high-temperature-resistant polyester elastomer is especially used in the electric wire industry around automobile engines. Background technique [0002] Thermoplastic Polyester Elastomer (Thermoplastic Polyester Elastomer, hereinafter referred to as TPEE) is a type of linear block copolymer containing PBT polyester hard segment (crystalline phase, providing strength) and soft segment (continuous phase). The rigidity, polarity and crystallinity of the hard segment of TPEE make TPEE have outstanding strength and good high temperature resistance, creep resistance, solvent resistance, oil resistance and impact resistance; the low glass transition temperature and saturation of the soft segment It has excellent low temperatur...
