Description
Technical Field

Background
Polyvinyl chloride (PVC) is one of five general synthetic resins in the world, and a product thereof is a general plastic product with high yield, although the PVC has wide application, the PVC is easy to accumulate static electricity due to friction in use so as to cause fire or explosion, and the PVC prevents the PVC from being used in the fields of coal, petroleum, chemical industry, textile, dangerous goods warehouse, electronic and wireless communication, semiconductor industry and the like. Since pure PVC does not meet the requirements for antistatic properties in these fields. Therefore, PVC has better antistatic performance and can be used in the fields of coal mine, petroleum, chemical industry, textile, dangerous goods warehouse, electronic and wireless communication, semiconductor industry and the like. At present, the domestic antistatic PVC system mainly comprises a PVC/carbon black system and a PVC/antistatic system, wherein the latter is mainly added with an antistatic agent with surface activity. The PVC/carbon black system is added with carbon black for conduction, and a conductive channel formed in the plastic blending system is utilized to play an antistatic role. But to make the surface resistance of PVC 1056-12 parts of the carbon black is required to be added for conducting static electricity, and the impact strength is obviously reduced along with the increase of the content of the carbon black. Thus, the application of the PVC/carbon black system is greatly limited. The PVC/antistatic system is mainly added with an antistatic agent with surface activity, the antistatic agent with surface activity in the system belongs to the fine chemical industry, the production has large pollution to the environment and high cost, and a plurality of products are harmful to human bodies. Graphene (graphene) is a two-dimensional nanomaterial, which is a single-layer two-dimensional material formed by connecting carbon atoms in sp2 hybridization. Due to the special structure, graphene has excellent performances which are not possessed by many other nano materials, such as excellent electric conduction and heat conduction performances, extremely high mechanical strength, extremely large specific surface area and the like. These properties make graphene an ideal two-dimensional nanofiller for the preparation of high performance polymer nanocomposites. Can improve the conductivity, mechanical property and thermal stability of the polymer, and make it in the field of polymer composite materialThe domain has higher application value.
