Problems solved by technology

[0003] For polypropylene materials, directly adding graphene powder cannot be well dispersed and fused in the resin. Therefore, it is urgent to find a way to effectively and uniformly disperse graphene in polypropylene materials and strengthen the interface. Bonding strength, improving the mechanical properties, oxidation resistance, acid and alkali resistance, electrical conductivity and thermal conductivity of the overall composite material

Abstract

The invention discloses a graphene-containing polypropylene color master batch. The graphene-containing polypropylene color master batch is prepared from polypropylene resin, carbon black, graphene powder, a dispersant, a coupling agent, additives and a high temperature stabilizer. The invention also discloses a preparation method of the graphene-containing polypropylene color master batch.

Description

technical field [0001] The invention belongs to the field of color masterbatch manufacturing, more specifically, the invention relates to a graphene-containing polypropylene color masterbatch and a preparation method thereof. Background technique [0002] Graphene, as the thinnest, strongest, and strongest new type of nanomaterial found so far, is called "black gold" and is the "king of new materials". It has very good strength, flexibility, electrical conductivity, and thermal conductivity. , Optical properties, in the fields of physics, materials science, electronic information, computer, aerospace and other fields have been developed by leaps and bounds. For the widely used traditional single polymer material, with the rapid development of science and technology and the increasingly stringent requirements for material properties, it can no longer meet the needs of both industry and technology in terms of mechanical properties, chemical stability, weather resistance and th...
