聚苯硫醚的产业发展概况与复合改性进展

Progress in Industry Development and Modification of Polyphenylene Sulfide

聚苯硫醚(PPS)是一种具有优异性能的特种工程塑料,广泛应用于环保、汽车、电子、石化、制药等行业。近年来,PPS应用领域在不断扩展,全球PPS需求量剧增,全球各大生产厂商为迎合市场纷纷扩大甚至建立新的生产线、增大产能。在全球PPS产业飞速发展的带动下,国内PPS行业也正在蓬勃发展。简要介绍了近年来国内外聚苯硫醚的产业发展状况。同时,为了进一步提高PPS的应用价值,增强其性能的同时降低成本,采用共混改性技术开发不同用途的PPS改性新品种成为该领域的研究热点之一。介绍了聚合物共混改性制备合金、无机粒子填充和增强纤维填充改性制备复合材料3种PPS改性技术的研究进展。

Polyphenylene sulfide （PPS） is a kind of engineering plastics with excellent comprehensive performance. It＇ s widely used in environmental protection, automobile, electronics, petrochemical, pharmaceutical and other fields. With the application expanding of PPS, the demand of PPS is soaring around the world in recent years. The main PPS manufac- turers have been setting up new production lines and increasing the production capacity to cater for the situation. With the rapid development of global PPS industry, the domestic PPS industry is booming as well. In order to further increase the application value of the PPS, it＇s necessary to enhance its performance and to reduce its costs. PPS modification via co- polymerization and especially blending modification have been a hot area of research. The PPS blending modification tech- nology mainly includes polymer blending, inorganic particle modification and fiber reinforcement modification. This paper briefly introduced the current state of the art of the PPS industry. Research progress on polymer blending with PPS, inor- ganic particle modification of PPS and fiber reinforced PPS were reviewed as well.
