有机磷-氮系协同阻燃剂的研究进展及其表征

摘要

Organic phosphorus-nitrogen synergistic flame retardants had great advantages in terms of halogen-free,non-toxicity,high efficience and environmental protection.The excellent flame-retardant property was supposed to benefit from the synergistic effect of flame-retardant phosphorus and nitrogen elements.Therefore,organic phosphorus-nitrogen synergistic flame retardants were regarded as vital flame retardants.The different structure of flame retardants and the characterization of organic phosphons-nitrogen synergistic flame retardants were discussed.In addition,the development trends of the organic phosphorusnitrogen synergistic flame retardants were prospected together with the important approaches of improving the phosphorus-nitrogen flame retardant properties.%有机磷-氮协同阻燃剂是一类无卤、无毒、高效、环保的阻燃剂,阻燃元素磷和氮的增效作用使其具有优异的阻燃性能,成为了有机高分子材料重要的阻燃剂之一.概述了不同结构的有机磷-氮协同阻燃剂的研究进展,对不同阻燃基材性能进行了总结,对阻燃剂结构的红外光谱、核磁共振光谱等表征方法进行简单阐述,最后对有机磷-氮协同阻燃剂发展前景进行展望,指出多种提高磷-氮协同阻燃剂阻燃性能的途径.
