The invention relates to the technical field of macromolecules, and particularly discloses a halogen-free flame-retardant polypropylene compound as well as a preparation method and application thereof. The halogen-free flame-retardant polypropylene compound is prepared from the following components in parts by weight: 60 to 90 parts of polypropylene, 10 to 30 parts of flame retardant, 0.5 to 2.0 parts of hindered amine, 0.2 to 1.0 part of benzoate and 0.1 to 0.8 part of antioxidant. The hindered amine and the benzoate are simultaneously added into a traditional halogen-free flame-retardant system, so that the oxygen index and the vertical flame-retardant property of the composition are remarkably improved, and the requirements of peripheral parts of a new energy automobile battery on materials are completely met.

本发明涉及高分子技术领域，具体公开了一种无卤阻燃聚丙烯复合物及其制备方法和应用。无卤阻燃聚丙烯复合物包括以下重量份数的组分：聚丙烯60～90份、阻燃剂10～30份、受阻胺0.5～2.0份、苯甲酸酯0.2～1.0份和抗氧剂0.1～0.8份。本发明在传统的无卤阻燃体系中同时添加受阻胺和苯甲酸酯，组合物的氧指数和垂直阻燃性能都得到了显著提升，完全满足新能源汽车电池周边零部件对于材料的需求。
