【摘要】 根据阻燃剂在聚氨酯中的化学反应性,可以将聚氨酯的阻燃剂分为非反应型阻燃剂、反应型阻燃剂和纳米材料阻燃剂三大类。并根据这三大类分别综述了阻燃聚氨酯的研究现状,简要介绍了各类阻燃剂的阻燃机理,阐述了其使用过程中存在的优缺点,并展望了阻燃聚氨酯的发展趋势。更多还原

【Abstract】 According to the chemical reactivity of the flame retardants in polyurethane,polyurethane flame retardants can be divided into three classes: non-reactive flame retardants,reactive flame retardants and nanomaterials flame retardants.The present research progress which based on these three categories is summarized.The flame retardant mechanism is briefly introduced,and the the future development trends of the flame-retardant polyurethane are described.更多还原
