摘　　要： 综述了卤系、聚合型有机磷系、磷-氮系和无机系等不同类型阻燃剂的阻燃特性及合成动向,重点介绍了阻燃剂在高分子材料中的应用及其阻燃效果。溴系阻燃剂发展的新特点是提高溴含量和增大相对分子质量。膨胀型阻燃剂符合当今要求阻燃剂少烟、低毒的发展趋势,是有望实现阻燃剂无卤化的途径之一。无机含结合水的阻燃剂必将向微细化及纳米化方向发展。纳米阻燃剂和微胶囊化技术将逐步得到应用。通过复配技术开发出性能优异的新型阻燃剂,是阻燃材料研究的重要课题,也是阻燃剂发展非常重要的方向。 This paper reviewed the syntheses and flame retarding characteristics of various halogen-based, polymeric organic phosphorus based and phosphorus-nitrogen based flame retardants, and emphatically introduced their applications in polymer materials as well as the flame retarding effectiveness. The new development of bromine-based flame retardants features raising bromine content and increasing relative molecular mass of the retardants. Dilatant flame retardants can satisfy the current development trend of less fume and low toxicity and thereby, being deemed as one of the ways for realizing the preparation of halogen-free flame retardants. Inorganic flame retardants with hydration water are expected to be prepared in the form of corpuscle or nano-particle. The technology for preparing nano-flame retardant and micro- encapsulation of flame retardant will be gradually employed. The development of novel flame retardants having superior performance through compounding technology not only becomes an important research subject, but also represents a significant study direction of the flame retardants.
