研究了聚磷酸铵、季戊四醇和三聚氰胺填充膨胀型阻燃聚丙烯的动态燃烧性能。为了评价材料的燃烧性能：极限氧指数、发烟量、拉伸强度，并对我们开发的“动态燃烧性能评价系统”进行了实验评价。结果表明，膨胀型阻燃剂填充聚丙烯具有上级阻燃性能，并保持其机械强度。还可以看出，燃烧时CO浓度和烟雾排放量减少。结果表明，该膨胀型阻燃剂是改善聚丙烯燃烧性能的有效阻燃剂。(C)1998爱思唯尔科技有限公司版权所有。
The dynamic flammability properties of an intumescent fire retardant polypropylene filled with ammonium polyphosphate, pentaerythritol and melamine was discussed in this study. To evaluate the flammability properties of the materials: limit oxygen index, smoke emission, tensile strength, and our exploitation 'dynamic flammability evaluation system' tests were assessed in experiments. The results showed that the intumescent fire retardant filled polypropylene has superior flammability properties and keeps its mechanical strength. It also can be seen that CO concentration and smoke emission decrease while burning. It is concluded that this intumescent system additives is an effective flame retardant on improving combustion properties for polypropylene. (C) 1998 Elsevier Science Ltd. All rights reserved.
