摘　　要：为了满足聚对苯二甲酸丁二醇酯(PBT)在工业设备中的应用需要,需对PBT进行改性处理。文章综述PBT在力学性能,阻燃性能、翘曲变形、析出性能及介电性能等方面的改性研究进展。介绍了PBT改性工程塑料在汽车、电子电器、机械设备、通信以及纺织等领域的应用。指出未来应当开发符合低碳环保且具有高附加功能的PBT材料,通过提升改性技术加快功能性PBT产品的开发。In order to meet the application needs of polybutylene terephthalate( PBT) in industrial equipment, PBT needs to be modified. The research progress of PBT in mechanical properties, flame retardancy, warpage, precipitation properties and dielectric properties is reviewed. The application of PBT modified engineering plastics in the fields of automobile, electronics, machinery and equipment, communication and textile was introduced. It is pointed out that PBT materials with low carbon environmental protection and high additional functions should be developed in the future, and the development of functional PBT products should be accelerated by improving the modification technology.
