| titleOfInvention | Preparation method of graphene heat conduction and dissipation film for floor |
| abstract | The invention discloses a preparation method of a graphene heat conduction and dissipation film for a floor, which comprises the following specific preparation steps: s1, adding graphene powder into the polyurethane emulsion, adding a surfactant, and uniformly stirring to obtain a graphene mixed emulsion; s2, uniformly coating the graphene mixed emulsion on a modified PET film, and coating the graphene mixed emulsion on the PET film by using a desktop coating machine, wherein the thickness of the graphene mixed emulsion is 10-20 microns; s3, drying the coated modified PET film at 70-90 ℃ for 8-16h to obtain a semi-finished graphene heat-conducting and heat-dissipating film; s4, carrying out hot rolling treatment on the semi-finished product of the graphene heat conduction and dissipation film by using a double-roller rolling machine to obtain the graphene heat conduction and dissipation film; according to the invention, the polyurethane emulsion is used as a solvent to disperse the graphene powder, so that the graphene is uniformly coated on the surface of the modified PET film, and meanwhile, the polyurethane emulsion forms a crosslinked cured layer after drying, so that the modified PET film is conveniently attached to a floor substrate, and the graphene sheet layer is protected. |
