Abstract

The invention discloses a polypropylene composition and a preparation method thereof. The polypropylene composition comprises the following components in parts by weight: 63-99 parts of polypropyleneresin, 0-33 parts of a toughening agent, 1-6 parts of superconducting carbon black, 1-5 parts of carbon nanotubes and 1-7 parts of a polyether polypropylene block copolymer. The superconductive carbonblack, the carbon nanotubes and the polyether polypropylene block copolymer are added into the polypropylene resin, and the polyether polypropylene block copolymer interacts with the superconductivecarbon black and the carbon nanotubes, so that the superconductive carbon black and the carbon nanotubes are uniformly dispersed, and the carbon nanotubes are dispersed among superconductive carbon black particles to play a bridging role; the conductive performance of the material can be remarkably improved, so that the polypropylene composition with high conductive performance and excellent mechanical performance is obtained, and the polypropylene composition can be used for preparing automobile electromagnetic shielding parts.

Description

technical field [0001] The invention relates to the technical field of polymer materials, in particular to a polypropylene composition and a preparation method thereof. Background technique [0002] Polypropylene (PP) has the advantages of low density, easy processing, and excellent mechanical properties, and has been widely used in the automotive industry, home appliances, and machinery. For the automobile industry, polypropylene is mainly used in interior and exterior parts of automobiles, interior parts such as instrument panels, door panels and pillars, etc., and exterior parts such as bumpers, fenders, deflectors, etc. With the rapid development of electronics and information technology, the demand for conductive materials is becoming more and more urgent. Conductive materials have a wide range of applications in fields such as antistatic and electromagnetic shielding. [0003] In order to improve the conductivity of polypropylene materials, many studies have been car...
