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...
