The present invention provides a permanently antistatic, injection moldable thermoplastic composition comprising a polybutylene terephthalate resin having an intrinsic viscosity in the range of about 0.7 to about 1.4 deciliters per gram measured in ortho-chlorophenol at 25°C., an antistatic dopant' comprising an electron acceptor compound, an electron donor compound, and polytetrafluoroethylene, and less than about 10 percent by weight based on the total weight of the molding composition of carbon fibers having lengths of about 0.1 to 1.0 inch (2.5 to 25 mm). Such a molding composition exhibits a volume resistivity of less than 1 x 108 ohm-cm, exceptional low wear performance, excellent mechanical properties, and ease of manufacture.
本发明提供了一种永久抗静电、可注射成型的热塑性塑料组合物,该组合物包含一种聚对苯二甲酸丁二醇酯树脂,其固有粘度在 25°C 下于邻氯苯酚中测得的范围内约为 0.7 至约 1.4 分升/克;一种抗静电掺杂剂,该掺杂剂包含一种电子受体化合物、一种电子供体化合物和聚四氟乙烯;以及按重量计占成型组合物总重量少于约 10%、长度约为 0.1 至 1.0 英寸(2.5 至 25 毫米)的碳纤维。 这种成型组合物的体积电阻率小于 1 x 108 欧姆-厘米,具有优异的低磨损性能、出色的机械性能和易制造性。
