软质PVC阻燃抑烟的研究

介绍了各类阻燃剂(如氢氧化铝、氢氧化镁、锑系、磷系、硼系、钼系)的性能及阻燃机理，并对软质PVC材料的阻燃抑烟性能进行了实验。结果表明：经偶联剂处理过的阻燃剂，由于增强了其与基体的界面结合力。从而使其力学性能得到提高；三氧化钼的用量对聚合物的阻燃效果影响不明显，而随着硼酸锌和三氧化二锑用量的增加，其阻燃效果越来越好。

Research on the fire retardancy and smoke suppression of soft PVC

The properties and fire-retardant mechanism of some kinds of fire retardants,such as aluminum hydroxide,magnesium hydroxide,antimony,phosphorus,boron and molybdenum,were introduced.The fire retardancy and smoke suppression of soft PVC were tested.The results showed that:(1)the mechanical property of coupling agent-treated fire retardant was improved since the interfacial combination between the fire retardant and matrix was enhanced;(2)the using amount of molybdenum trioxide had no significant influences on the fire-retardant effect,but the fire-retardant effect could become better and better with the increase of the using amount of zinc borate and antimony trioxide.
