Polypropylene/nylon composite material with high barrier property, preparation method of polypropylene/nylon composite material, high polymer material product and application of high polymer material product

The invention belongs to the field of polymer material processing, in particular relates to a polypropylene/nylon composite material with high barrier property, a preparation method of the polypropylene/nylon composite material, a high polymer material product and application of the high polymer material product. The polypropylene/nylon composite material is prepared from the following raw materials: S1, 48 to 90wt% of polypropylene, S2, 2 to 20wt% of nylon, S3, 2 to 10wt% of a graphene premix, S4, 5 to 20wt% of an elastomer, S5, 1 to 10wt% of a solubilizer, and S6, an auxiliary agent bag. Thegraphene premix is prepared from the following raw materials: S3-1, graphene, S3-2, water, S3-3, latex, and S3-4, a flocculating agent. The polypropylene/nylon composite material has high barrier property, especially has good barrier effect on small molecular gases (such as hydrogen and nitrogen), and meanwhile, the wear resistance and scratch resistance of the composite material are improved. 本发明属于高分子材料加工领域，尤其涉及一种高阻隔性的聚
