| 摘 要： | 碳酸镍对多聚磷酸蜜胺（MPP）和笼状季戊四醇磷酸酯（PEPA）复配阻燃聚丙烯体系具有较好的阻燃协同作用。采用TGA、FTIR研究了碳酸镍（NC）对阻燃聚丙烯的热降解行为，并用Flynn-Wall方法模拟体系的热降解动力学。TGA测试表明NC能有效地增加材料的残炭含量；FTIR和热降解活化能分析结果表明在降解过程中，NC能促使材料生成更多的P—O—C和P—O—P的交联结构，并提高材料的热降解活化能。

| Abstract: | Nickel carbonate（NC） proves to be an effective synergistic agent for halogen-free flame retardant polypropylene by using Melamine polyphosphate （MPP） and 1-oxo-4-hydroxymethyl- 2,6,7-trioxa-1-phospha-bicyclo2.2.2]octane （PEPA）. TGA and F＇FIR are used to investigate thermal degradation behavior of halogen-free flame retardant polypropylene synergized by NC and thermal degradation kinetics by Flynn-Wall method. TGA results show that NC yield higher amount of carbonaceous chars, FTIR and apparent activation energy results by Flynn-Wall method show that NC can catalyze connection reaction between MPP/PEPA to form more P-O-P and P-O-C structure and increase the activation energy of flame retardant PP during thermal degradation of materials. |
