Abstract

The invention discloses a PVC (Polyvinyl Chloride) / graphite alkene antistatic composite material. The PVC graphite alkene antistatic composite material is prepared by the following ingredients in percentage by weight: 2-20% of a shock resistance modifying agent, 0.5-10% of an electric conductive filler, 2-20% of a processing agent and the balance of matrix resin. In addition, the invention also provides a preparation method of the PVC / graphite alkene antistatic composite material. Due to the adoption of the preparation method, the PVC has the antistatic property, and the enhancing and toughening are realized at the same time; and the surface resistivity of the prepared PVC / graphite alkene antistatic composite material is 104-108 omega, the volume resistivity is not more than 108 omega / cm, the tensile strength is not less than 50MPa, the impact strength is not less than 5kJ / m<2>, the elongation at break is not less than 75%, and the antistatic requirements on GB / T20105-2006 and MT164-2007 and MT165-2007 in the colliery industry are met.

Description

technical field [0001] The invention belongs to the technical field of polymer materials, and in particular relates to a PVC / graphene antistatic composite 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,...
