Title:
POLYPROPYLENE COMPOSITION AND PREPARATION METHOD THEREFOR
Document Type and Number:
WIPO Patent Application WO/2019/042054
Kind Code:
A1
Abstract:
A polypropylene composition, comprising 60-85 parts by weight of polypropylene resin, 5-10 parts by weight of high-density polyethylene resin, 5-20 parts by weight of a dendritic flexibilizer, 1-5 parts by weight of graphene, and 3-5 parts by weight of a surface modifier. By adoption of the dendritic flexibilizer, the good impact performance of a material can be maintained under the condition of lower dosage, and moreover, the chemical-resistance performance of the polypropylene material is facilitated to be improved; the added surface modifier changes the surface tension of the material, and can effectively reduce the erosion of chemicals to the surface of the material; the added graphene not only improves the bending modulus of the material, but also has a nano-blocking effect on the chemicals, thereby inhibiting the erosion of the chemicals. By means of the synergism of the dendritic flexibilizer, the surface modifier, and the graphene, the obtained polypropylene material composition has excellent chemical-resistance performance, and maintains good rigid-tough balance. In addition, the obtained polypropylene material has no defects such as fiddle back figures after injection molding, and has special metal luster.
