Abstract

The invention relates to a glass fiber and graphene hybrid filler filled polypropylene composite material and a preparation method thereof. The glass fiber and graphene hybrid filler filled polypropylene composite material comprises the following components: 45-85 parts of polypropylene, r 10-50 parts of glass fiber, and 0.0001-1 part of graphene. The glass fiber is chopped glass fiber with a flatsection, and the width-to-thickness ratio of the section is 2-10. The preparation method utilizes electrostatic self-assembly principle to realize coating of glass fiber with graphene oxide, melt blending and in-situ reduction of graphene oxide can be realized synchronously. The invention has the advantages that: as the graphene carrier, glass fiber can realize even dispersion of a minute quantity of graphene in the matrix, a conductive network is formed to substantially lower the material surface resistance, an excellent antistatic effect can be achieved, and the stable physical and chemicalproperties of graphene endow the material with long-acting antistatic properties under moist, heating, insolation, vibration and other harsh conditions.

Description

technical field [0001] The invention relates to the technical field of polypropylene modification, in particular to a polypropylene composite material filled with glass fiber and graphene hybrid filler. Background technique [0002] Polymer materials are indispensable in modern society. In some application fields or occasions, it is required to have antistatic function to avoid the harm caused by the accumulation of static electricity. Plastics widely used in daily life and industry, such as polypropylene, polyethylene, polyvinyl chloride, nylon, PC, ABS, PBT, PET, etc. are all covalently bonded, and the molecular chain is difficult to generate free charges, so it has a very high The surface resistance and volume resistance belong to the category of insulators. [0003] Endowing polymer materials with antistatic properties essentially reduces the surface resistance of the material. The current practice is to add an antistatic agent to the polymer. The most widely used ant...
