DETAILED DESCRIPTION - A porous titanium carbide MXene/reduced graphene oxide base warm brick comprises heat preservation layer, a porous titanium carbide MXene/reduced graphene oxide-based conductive membrane and a tile layer. The porous titanium carbide MXene/reduced graphene oxide-based conductive membrane sandwiched between the heat preservation layer and the tile layer. The porous titanium carbide MXene/reduced graphene oxide-based conductive membrane comprises transparent insulating layer (A), a porous titanium carbide MXene/reduced graphene oxide-based conductive membrane, a transparent insulating layer (B), and electrodes. The transparent insulating layer (A) covers one side of the porous titanium carbide MXene/reduced graphene oxide-based conductive membrane. The transparent insulating layer (B) covers the other side of the porous titanium carbide MXene/reduced graphene oxide-based conductive membrane. One end of the electrode is electrically connected with the porous titanium carbide MXene/reduced graphene oxide-based conductive membrane. The other end of the electrode extends outside the transparent insulating layer (A) or the transparent insulating layer (B). The preparation of the porous titanium carbide MXene/reduced graphene oxide-based conductive membrane involves providing graphite powder and titanium aluminum carbide powder, grinding the graphite powder and titanium aluminum carbide powder to a fineness of 200 mesh or more, mixing graphite powder with titanium aluminum carbide powder and pressing to form a working electrode, fixing the working electrode in the electrolytic cell, adding electrolyte to the electrolytic cell so that the working electrode is immersed in the electrolyte, using working electrode as a positive electrode and applying a voltage to ionize the fluorine-containing anion liquid to generate fluorine radicals, electrolyzing, centrifuging the electrolyte to collect the precipitate, obtaining titanium carbide/graphite oxide material, dissolving the titanium carbide/graphite oxide material in isopropanol according to the mass-volume ratio of 50-500 mg/mL, ultrasonically processing with isopropanol containing titanium carbide/graphite oxide material, centrifuging at 8000-15000 rpm for 10-30 minutes, collecting the precipitate, immersing in a reducing reagent to reduce, centrifuging, collecting the precipitate, drying, dispersing the dried precipitate in dispersant (d1), ultrasonically processing in water bath, obtaining titanium carbide MXene/reduced graphene oxide dispersion liquid, mixing particulate powder and dispersant (d2), adding 50-500 mg/mL resin, obtaining particulate resin slurry, mixing the particulate resin slurry, titanium carbide MXene/reduced graphene oxide dispersion, polyacrylonitrile-maleic anhydride copolymer and stabilizer in a mass ratio of 500:1000-10000:1-50:5-20, mixing, and transferring to a protective gas environment and stirring at 65-85 degrees C until the volume is concentrated to 1/2-1/6, obtaining porous titanium carbide MXene/reduced graphene oxide-based conductive ink, forming into a membrane by scraping or printing, immersing in a dilute acid solution, washing and drying. The titanium aluminum carbide powder is titanium-aluminum carbide (Ti3AlC2) powder or titanium-aluminum carbide (Ti2AlC) powder. The particulate powder is carbonate powder or metal oxide powder. The mass ratio of the graphite powder to the titanium aluminum carbide powder is 1-10:1. The electrolyte is a fluorine-containing anion liquid as an etching agent. The diameter of the particulate powder is 0.1-1 mu m. The concentration of the particulate powder is 10-100 mg/mL. The concentration of the resin is 50-500 mg/mL.
