以聚丙烯为基体,多聚磷酸铵(APP)/季戊四醇(PER)/凹凸棒(ATP)为复配阻燃剂(其中APP/PER质量比为3:1),通过熔融共混的方法制备聚丙烯复合材料.采用透射电子显微镜(TEM)考察原土ATP的微观形貌和PP/APP/PER/ATP复合材料的阻燃性能及力学性能.实验结果表明:ATP与APP/PER对PP有协同阻燃作用.当ATP质量含量为2%,复配阻燃剂APP/PER/ATP总量为26%时,PP/APP/PER/ATP复合材料的氧指数为32%,拉伸强度比纯PP提高4.3%,冲击强度比纯PP也提高15.2%.
以聚丙烯為基體,多聚燐痠銨(APP)/季戊四醇(PER)/凹凸棒(ATP)為複配阻燃劑(其中APP/PER質量比為3:1),通過鎔融共混的方法製備聚丙烯複閤材料.採用透射電子顯微鏡(TEM)攷察原土ATP的微觀形貌和PP/APP/PER/ATP複閤材料的阻燃性能及力學性能.實驗結果錶明:ATP與APP/PER對PP有協同阻燃作用.噹ATP質量含量為2%,複配阻燃劑APP/PER/ATP總量為26%時,PP/APP/PER/ATP複閤材料的氧指數為32%,拉伸彊度比純PP提高4.3%,遲擊彊度比純PP也提高15.2%.

A flame-retardant material of polypropylene (PP)/ammonium polyphosphate (APP)/pertaerythritol (PER)/ attapulgite(ATP) was prepared via melt compounding based on polypropylene (PP) , APP, PER and other aid agents. The morphology of ATP was studied by transmission electron microscopy (TEM).The flammability and mechanical properties of PP composite were investigated by LOI experiments, tensile and impact. Compared to tradition flame retardant/PP composite, the LOI of PP composite with 2 % ATP increased from 30 % to 32 %.The tensile strength and impact strength of PP composite increased by 4.3 % and 15.2 % ,respectively.
