Graphene heating ceramic tile

Abstract

The invention relates to the technical field of building ceramics, and discloses a graphene heating ceramic tile, which comprises a ceramic tile base body and a polyurethane insulation board. A graphene heating chip is clamped between the ceramic tile base body and the polyurethane insulation board; and the graphene heating chip and the polyurethane insulation board are integrally formed in a foaming mode. The graphene heating chip comprises a graphene heating film and connecting terminals. The graphene heating film comprises a PET base film and a plurality of graphene heating coatings which coat the PET base film and are in a rectangular surface shape. The graphene heating coatings are thermally coated with polymer insulating films; silver electrode strips are arranged at the bottoms of the two ends of each graphene heating coating, and graphene strips are arranged between the silver electrode strips and the PET base film; the adjacent graphene heating coatings are connected in parallel through electrode connecting sections; electrode current-carrying strips are arranged on the upper surfaces of the graphene heating coatings and the electrode connecting sections; and the connecting terminals pass through the electrode current-carrying strips and are fixed to the graphene heating coatings. The graphene heating ceramic tile is good in heat preservation performance, high in heatefficiency, stable in structure and easy to construct and maintain.

Description

technical field [0001] The invention relates to the technical field of architectural ceramics, in particular to a graphene heating ceramic brick. Background technique [0002] In my country, floor heating mainly includes water floor heating and electric floor heating. The installation of water floor heating is complicated and the maintenance cost is high. Electric floor heating products are mostly composed of ceramic tiles and heating elements. The heating elements mainly include carbon crystals, electric heating wires and carbon fibers. Among them: Carbon crystal floor heating has short service life, complex construction, high cost and high energy consumption; electric heating wire floor heating has large electromagnetic radiation, slow heating, and high energy consumption; carbon fiber floor heating is easy to age and has a short life. [0003] As a new material, graphene has excellent optical, electrical and mechanical properties. When the graphene heating film is energize...
