The invention belongs to the technical field of high polymer materials, and discloses an asphalt-resistant polypropylene composition as well as a preparation method and application thereof. The polypropylene composition comprises polypropylene resin, HDPE, an amide lubricant, a nucleating agent, a flexibilizer and a filler, the isotacticity of the polypropylene resin is greater than or equal to 98%, and the nucleating agent is at least one of carboxylic acid metal salt or organic phosphoric acid metal salt; according to the polypropylene composition provided by the invention, the HDPE, the amide lubricant and the specific type of nucleating agent are added into the polypropylene with specific isotacticity for comprehensive modification, so that the obtained polypropylene composition not only keeps good mechanical properties, but also has the advantage of asphalt resistance.

    本发明属于高分子材料技术领域,公开了一种耐沥青的聚丙烯组合物及其制备方法和应用。该聚丙烯组合物包括聚丙烯树脂、HDPE、酰胺类润滑剂、成核剂、增韧剂和填料,其中,所述聚丙烯树脂的等规度≥98%,所述成核剂为羧酸金属盐或有机磷酸金属盐的至少一种;本发明提供的聚丙烯组合物通过在特定等规度的聚丙烯中添加HDPE、酰胺类润滑剂和特定种类的成核剂进行综合改性,得到的聚丙烯组合物既保持了良好的力学性质,又具有耐沥青的优点。
