Problems solved by technology

The biggest problem with this method is that the liquid medium only acts as a solvent, and the liquid medium needs to be removed after graphite exfoliation is completed, and removing the solvent is precisely the biggest problem faced by graphene applications.

Abstract

The invention provides a graphene composite PVC material and a preparation method thereof, and belongs to the technical field of PVC materials. Comprising the following raw materials in parts by weight: 7-12 parts of porous graphene hollow microspheres, 70-100 parts of PVC resin, 1-2 parts of a compatilizer, 0.5-1 part of an antioxidant, 0.2-0.5 part of monoglyceride, 5-10 parts of a plasticizer and 1-3 parts of a heat stabilizer. According to the invention, the compatibility of the inorganic porous graphene hollow microspheres in PVC resin is improved, so that the mechanical properties of the PVC plastic are not greatly changed, the antistatic property of the PVC plastic is greatly improved due to good conductivity of graphene, and the preparation method is simple, wide in raw material source and wide in application prospect.

Description

technical field [0001] The invention relates to the technical field of PVC materials, in particular to a graphene composite PVC material and a preparation method thereof. Background technique [0002] PVC has the advantages of flame retardant, chemical corrosion resistance, wear resistance, excellent electrical insulation and high mechanical strength. It is widely used in various fields and is the second largest general-purpose plastic in output after polyethylene. But the surface resistance of PVC is as high as 10 14 Ω-10 17 Ω is easy to generate static electricity, which is easy to cause explosion and fire. Improving the antistatic ability of PVC materials can broaden its application in chemical industry, coal mine, electronics and other fields. Using traditional processing methods, it is difficult for PVC to achieve a surface resistivity of 3.0×10 for a long time 8 Antistatic requirements of GB / T20105-2006 and coal mining industry MT164-2007, MT165-2007 below Ω.
