Abstract

The invention relates to a polypropylene composition as well as a preparation method and application thereof. The polypropylene composition comprises polycarbonate, graphene, a compatilizer and other processing aids. According to the polypropylene composition provided by the invention, the use amount of the graphene is reasonably adjusted, and meanwhile, a specific compatilizer namely glycidyl methacrylate grafted PP is added, so that graphene can be well dispersed, and the light transmittance of the polypropylene material is effectively improved.

Description

technical field [0001] The invention belongs to the field of polymer materials, and in particular relates to a polypropylene composition and its preparation method and application. 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. In the automotive industry, polypropylene is mainly used in automotive interior and exterior trims (such as instrument panels, door panels, and pillars, etc.) and exterior trims (such as bumpers, fenders, deflectors, etc.). For automotive interior parts, since there are many ambient lights inside the car to enhance the visual enjoyment of drivers and passengers, it is necessary for the interior and exterior parts of the car to have better light transmittance, that is, to increase the light transmittance of the car interior materials. [0003] At present, the materials of automo...
