Heat-resistant polypropylene material as well as preparation method and application thereof

The invention discloses a heat-resistant polypropylene material as well as a preparation method and application thereof. The heat-resistant polypropylene material comprises the following components in parts by weight: 60-70 parts of polypropylene, 20-30 parts of glass fibers, 5-10 parts of mica and 4-10 parts of an auxiliary agent. The heat-resistant polypropylene material disclosed by the invention simultaneously has excellent thermo-oxidative aging resistance, low warping property, excellent mechanical strength and high and low temperature resistance, and can meet various performance requirements of household appliances on the material. In addition, mica is introduced into the polypropylene material, so that the gloss and flatness of the polypropylene material can be remarkably improved, and the material has excellent appearance. 本发明公开了一种耐热聚丙烯材料及其制备方法和应用，所述耐热聚丙烯材料包括以下重量份的组分：聚丙烯60～70份，玻璃纤维20～30份，云母5～10份，助剂4～10份。本发明中的耐热聚丙烯材料同时兼具优异的耐热氧老化性能、低翘曲性、优异的力学强度、耐高低温性能，可以满足家用电器对材料的各项性能要求。此外，本发明通过在聚丙烯材料中引入云母，可以显著提高聚丙烯材料的
