| 摘 要： | 引言 软质PVC制品中由于大量增塑剂的加入,大大提高了其可燃性,燃烧时还会产生大量有毒烟雾,因此对PVC制品的阻燃抑烟问题亟待解决.无机氢氧化物优点众多,在阻燃高分子材料中应用广泛,但阻燃效率低,常与其他阻燃剂复配使用.硼酸锌、锡酸锌、磷酸锌、氧化锌等可直接或与其他阻燃剂复合应用于PVC的阻燃消烟[1-3].

| Abstract: | ZnO and metal hydroxides as flame-retardants and smoke suppressants for flexible poly(vinyl chloride) were studied.The thermal degradation in air of flexible PVC treated with flame-retardants ZnO and metal hydroxides was studied with differential thermal analysis and thermogravimetry from ambient temperature to 1073 K.The kinetic parameters were obtained by using the equation of Kissinger, Broido and Vyazovkin.Their mechanisms were studied through comparing the thermal behavior with the flame retardant properties of the samples.The results showed that the flame retardant properties of the samples treated with ZnO and metal hydroxides were related to the thermal behavior of the samples.Metal hydroxides enhanced the activation energy of degradation and the flame retardant properties of the samples through endothermic dehydration.ZnO might act in the condensed phase as a Lewis acid. |
