Abstract

The invention discloses a conductive polypropylene nano composite material comprising polypropylene, a conductive agent, a compatibilizer, a dispersant, a heat stabilizer and a processing aid, whereinthe conductive agent consists of compositions at least containing a first conductive component, the first conductive component is a metal-organic framework material MOFs, a metal ligand of the material is aluminum, and an organic ligand of the material is a polycarboxy aromatic compound. According to the conductive polypropylene nano composite material, the MOFs having the specific metal center and organic ligand as the first conductive component is added into the polypropylene material, carbon nanotubes, graphene, carbon fibers, conductive metal powder and the like are added as a second conductive component, a sulfobetaine having a specific structure is used as a dispersing agent for cooperation, and maleic anhydride grafted polypropylene having a specific grafting ratio is used as a compatibilizing agent to enhance the dispersion of the conductive agent in a resin matrix, and through the synergistic effect of the components, the polypropylene composite material has better conductivity.

Description

technical field [0001] The invention relates to a polypropylene composite material and a preparation method thereof, in particular to a conductive polypropylene nanocomposite material and a preparation method thereof, belonging to the technical field of modified polymer materials. Background technique [0002] Polypropylene is the most widely used general-purpose plastic. Compared with other general-purpose plastics, it has the advantages of low cost, excellent mechanical properties, good chemical resistance, good insulation, high transparency and low water absorption, but at the same time, polypropylene is also Has the problem of not being able to conduct electricity. In order to broaden the application field of polypropylene materials in terms of conductivity, a large number of researches on the modification of polypropylene conductivity have been carried out in the prior art. Most of the modification methods currently used in the prior art are to add at least one of grap...
