The invention relates to a polypropylene composite material and a preparation method thereof. The polypropylene composite material comprises polypropylene resin, transition metal modified carbon nanotubes, a sulfonamide compound and a flexibilizer. The problem of electromagnetic shielding is solved by adding the transition metal modified carbon nanotubes, and through cooperation of the sulfonamide compound and the transition metal modified carbon nanotubes, not only can a light hydrocarbon solvent be captured through the modified carbon nanotubes, but also the light hydrocarbon solvent can react with the sulfonamide compound on the surfaces of the modified carbon nanotubes; and the sulfonamide compound is a compatilizer between the modified carbon nanotube and the polypropylene, so that the performance of the modified carbon nanotube and the polypropylene is better, and the obtained polypropylene composite material meets the requirements of electromagnetic shielding, solvent resistance and high performance of the radar bracket.

    本发明涉及一种聚丙烯复合材料及其制备方法,包括聚丙烯树脂、过渡金属改性碳纳米管、磺酰胺化合物和增韧剂。本发明通过添加过渡金属改性碳纳米管解决电磁屏蔽问题,通过磺酰胺化合物和过渡金属改性碳纳米管的配合不仅能通过改性碳纳米管俘获轻烃类溶剂,而且能够和磺酰胺化合物在改性碳纳米管表面进行反应,而且磺酰胺化合物又是改性碳纳米管和聚丙烯之间的相容剂,使得改性碳纳米管与聚丙烯性能更好,得到的聚丙烯复合材料满足雷达支架电磁屏蔽、耐溶剂、高性能的需求。
