Abstract

The invention discloses an antistatic coating and a preparation method thereof, and application of antistatic coating. The antistatic coating comprises the following component in parts by weight: 100parts of PVC paste resin, 0-50 parts of vinyl chloride-vinyl acetate paste resin, 2-8 parts of a stabilizer, 2-10 parts of calcium carbonate, 1-5 parts of stearic acid and 80-400 parts of graphene slurry, wherein the graphene slurry comprises the following components in parts by weight: 1-5 parts of graphene, 1-5 parts of carbon nanotubes, 100 parts of a plasticizer and 0.5-5 parts of polyvinylpyrrolidone, and the antistatic coating does not contain a solvent. The antistatic coating provided by the embodiment of the invention can effectively enhance the mechanical properties of the PVC base material on the premise of ensuring the antistatic effect of the PVC base material; and moreover, a coating formed by the antistatic coating is thin, so that the production cost can be effectively reduced.

Description

technical field [0001] The invention relates to an antistatic coating suitable for PVC substrates, in particular to an antistatic coating and a preparation method and application thereof, belonging to the technical field of graphene / polymer composite materials. Background technique [0002] PVC has long been one of the most important polymer products in people's production and life. It is loved by people because of its good flame retardancy, excellent wear resistance, strong chemical corrosion resistance, and low gas and water leakage. , It has also become the second largest plastic consumer product in the world whose consumption is second only to that of polyethylene. However, with the development of society, people have higher and higher requirements on the performance of PVC. Substituting plastic for steel will become the mainstream trend of plastic development in the future. Although PVC has mechanical properties, corrosion resistance, water and gas leakage resistance O...
