PBT材料的共混改性研究

Blending modification of poly butylene terephthalate

为了克服聚对苯二甲酸丁二酯(PBT)性能的缺点,扩大应用领域,进行了PBT材料的共混改性研究。主要研究了PBT/ABS合金材料的性能以及RDP阻燃剂对PBT材料性能的影响。

Poly （butylene terephthalate）（PBT）resin has broad prospect of application in the machinery, automotive, electrical and electronics, household appliances, instruments, and other fields, owing to its excellent comprehensive performance. PBT has become the fastest growing one in the five most important engineering plastics. However, pure PBT itself has some disadvantages, e.g. , low notched impact strength, poor rigidity at high temperatures and poor flame retardancy. Therefore, many efforts though modification have been made to achieve high performance and broaden the application areas of PBT. This paper studies the properties of PBT/ABS alloy materials, the effect of RDP on flame retardant for PBT.
