待研发的阻燃剂及阻燃高分子材料新秀

自上世纪90年代初以来,开发新的阻燃剂及阻燃材料的困难即明显增加.一方面,环保法规对传统的阻燃材料提出了严格的挑战;另一方面,工业部门希望阻燃产品保持尽可能低的价格.而有些新的阻燃材料仍待开发,甚至可以说是急需.本文论述的就是几种有市场容量或有应用前景、值得研发的阻燃剂及阻燃高分子材料新秀,它们是:硫衍生物阻燃剂,实用的阻燃棉-聚酯混纺织物,耐久性阻燃棉织物,耐久性阻燃木材,耐候性阻燃涂料、无卤V-0级PBT及低烟苯乙烯系塑料.

Novel flame retardants and flame-retarded polymeric materials which are worth developing

Since the beginning of 1990s,the difficulties of developing new flame retardants and flame-retarded materials have been increasing.On one side,the environmental regulations have gave stringent challenges to the traditional flame-retarded materials.On the other side,the industrial users always want the flame-retarded materials to keep the lowest possible price.But some flame retardants and flame-retarded polymeric materials which have large marketing or are promising in industrial applications are waiting for developing.This paper described a number of these materials.They are sulfur derivatives as flame retardants,applicable flame-retarded cotton-polyester blend fabrics,durable flame-retarded cotton textiles,durable flame-retarded wood,weatherable flame-retarded coatings,nonhalogen PBT with V-0 grade,and low smoke styrenic plastics.
