膨胀型阻燃剂的研究进展

Research Status of Intumescent Flame Retardant

随着易燃高分子材料的广泛应用,阻燃剂也得到了广泛的应用,同时对阻燃剂的阻燃性、相容性等特性也有了更高的要求。膨胀型阻燃剂具有阻燃效率高、低烟、低毒等优点,因此成为阻燃剂的重要发展方向。简单介绍了膨胀型阻燃剂的阻燃机理,重点综述了近年来国内外膨胀型阻燃剂的最新研究进展和阻燃剂生产的新技术。最后指出了目前膨胀型阻燃剂研究存在的问题,也对该领域未来的研究方向提出了建议。

With the wide application of flammable polymer materials, flame retardant is used widely. At the same time, better flame resistance, higher compatibility and other characteristics of the flame retardant are required. Intumescent flame retardant has some advantages, such as high efficiency, low smoke and low toxicity, and has be- come an important development direction of flame retardant. Mechanism for flame retardancy and classification of ex- pandable flame retardant is introduced briefly, followed by a description of the state-of-the-art research progress of the intumescent flame retardant and the new technology of flame retardant production. In the end, problems of the current intumescent flame retardant research are pointed out, and advices for future development direction are also provided in this field.
