Problems solved by technology

The method of the present invention obtains the conductive foam by adsorbing the graphene conductive film on the surface of the foam, and the prepared conductive foam has the advantages of low density, high electrical conductivity, large specific surface area, and low cost, but it also has many shortcomings, for example, it only Graphene is coated on the surface of the foam, but there is no suitable fixing method to fix the graphene, so that the graphene on the surface of the conductive foam obtained by this invention is easy to fall and lose with friction, and it only passes through Graphene, a conductive material, conducts electricity to it, so its resistivity tends to be high

Abstract

The invention relates to a polymer emulsion, in particular to a polymer-based conductive treating emulsion and a method of using the same. The polymer-based conductive treating emulsion comprises, byweight, 100 parts of epoxy hydrocarbon modified silicone oil, 30-45 parts of polysilane-grafted graphene oxide, 10-20 parts of polyaniline, 10-15 parts of zinc powder, 5-10 parts of an emulsifier, 60-80 parts of distilled water, 3-8 parts of a co-emulsifier, 1-5 parts of a surfactant, and 0.5-3 parts of glacial acetic acid. The polymer-based conductive treating emulsion has the advantages that a conductive filler and an emulsion have good compatibility, and the conductive filler can be distributed evenly in the conductive emulsion; solidification of the emulsion helps effectively fix the conductive filler to the surface of a base; the emulsion herein has excellent electrical conductivity.

Description

technical field [0001] The invention relates to a polymer emulsion, in particular to a polymer-based conductive treatment emulsion and a use method thereof. Background technique [0002] Generally, high molecular polymers are insulators, such as cable materials wrapped in the outer layer of cables and housings of household appliances, so they play a very important role in the electrical industry. However, due to the insulating properties of high molecular polymers, there are certain problems. For example, high molecular polymers are easy to accumulate static electricity. In some cases, the accumulated static electricity is easy to hurt people or even cause fires. At the same time, in some cases, it is necessary to shield electromagnetic signals, and polymers are powerless. [0003] For example a kind of preparation method of a kind of graphene conductive foam reported on the Chinese patent literature, its authorized announcement number is CN102557022B, this inventive method...
