Detailed Description

In the following description, numerous specific details are set forth in order to provide a more thorough understanding of the present invention. It will be apparent, however, to one skilled in the art, that the present invention may be practiced without one or more of these specific details. In other instances, well-known features have not been described in order to avoid obscuring the present invention.

The existing central heating mode needs to consume a large amount of financial resources and material resources in the installation of a heating system, the heat loss is serious in the transmission process, and in most areas in the south, the central heating system cannot be adopted as the heating mode in consideration of the reasons of climate, cost and the like. The electric heating system, for example, uses the electric heating elements (heating cables, carbon crystal plates, electric heating plates) directly arranged under the floor F, and gradually expands the application market in the south and part of the north areas due to the advantages of flexibility, easiness in adjustment, convenience, independence, strong operability and the like. However, because the electric heating element is not completely attached to the floor F, the process is complex and tedious in the installation process, and a gap between the electric heating element and the cement layer can cause a large amount of heat loss in the heating process.

Therefore, the applicant considers that the electric heating coating is coated on the substrate A, the electric heating element and the floor F are integrated, and the insulating layer and the heat insulation layer are added, so that the complicated flow of the multilayer structure in the electric heating system during installation is simplified, and the gap between the electric heating element and the floor F is eliminated. Composite materials such as carbon black, carbon fiber, carbon nanotube, graphite alkene, teflon are preferred to electric heat coating as conductive coating, wherein the utility model discloses preferred graphite alkene is as electric heat coating. The graphene is a two-dimensional honeycomb carbon material formed by tightly stacking single-layer carbon atoms, and has high thermal conductivity and excellent electrical properties. Particularly, the chemically modified graphene has abundant functional groups on the surface, so that the graphene can realize nanoscale dispersion in a polymer matrix, and the electrical property of the polymer is effectively improved.

As shown in the attached figure 1, the utility model discloses a modular graphite lamination composite floor heating plate of preparation, include: the graphene electric heating packing layer comprises a substrate A, a graphene electric heating packing layer B coated on the substrate A, an insulating sealing layer C used for sealing the graphene packing, a metal heat conduction layer E which is fixedly arranged on the insulating sealing layer C and is latticed, a floor F arranged on the metal heat conduction layer E in a detachable mode, honeycomb aluminum D filled in the metal heat conduction layer E, and an electrode electrically connected with the graphene packing.

In the further implementation process, the substrate A is foamed ceramic with excellent heat insulation performance. The foamed ceramic with the thickness of 4.5cm and the heat conductivity coefficient of 0.19W/(m.K) is preferably used as a heat insulation layer to reduce the heat conduction to the ground.

In the further implementation process, the insulating sealing layer C is obtained by uniformly coating a silicone sealing adhesive on the graphene electric heating filler layer B and curing. On the one hand, the graphene is used as an insulating sealing layer C to protect the integrity of graphene and avoid the problem of electric leakage, and on the other hand, the graphene is used as an adhesive to be connected with a slowly coupling metal heat conduction layer E.

In the further implementation process, the metal heat conduction layer E is integrally formed by adopting metal aluminum materials, and a plurality of air exchange grids which are uniformly distributed and are in a honeycomb shape are arranged on the metal heat conduction layer E. Because the heat transfer rate of metal heat-conducting layer E is very fast, and it is even to be heated for each part of floor F and the room that it is located can both be better heating effect, and secondly, the heat preservation effect of honeycomb ventilation grid is good, and heat utilization rate is the energy can be saved.

In the further implementation process, the floor F is provided with a protruding part, the protruding part of the floor F of the protruding part is matched with the inner contour of the ventilation grid and is of a mortise-tenon structure, and the protruding part is sleeved with an elastic ring. Through the grid of taking a breath with the detachable fixed mounting in the top of graphite alkene packing layer in floor F, the graphite alkene circuit in the later stage of being convenient for detects, simultaneously because graphite alkene circuit's life can reach 50 years, is far above ordinary floor F's life, also convenience of customers changes the floor F of different styles, improves user experience and feels.

In order to facilitate understanding of the technical scheme of the combined graphene laminated composite floor heating plate, the preparation process thereof is briefly described: the method comprises the steps of coating graphene electrothermal coating on a substrate A through an automatic coating machine, setting the coating speed of the automatic coating machine to be 10-30 mm/s, adjusting the height of a hanging knife, and coating the graphene electrothermal coating to be 5-10 mm in thickness to obtain the electrothermal coating. And after the electrothermal coating is completely dried and cured, coating the conductive silver adhesive on two ends of the dried electrothermal coating, placing the sample in a drying oven, drying in the drying oven at the temperature of 60-80 ℃ for 3-5 hours to promote the curing of the conductive silver adhesive, then pasting double-sided conductive copper adhesive on the cured conductive silver adhesive, and leading out the conductive copper adhesive to serve as an electrode, thereby preparing the electrothermal coating substrate A. Then, uniformly coating the single-component silicone sealant serving as an electric insulating material on the cured electric heating coating; then, immediately adhering the latticed metal heat conduction layer E with the thickness of 3cm to the insulating sealing layer C, standing for 1-2 hours, and completely curing the silicone sealant; finally, the floor F with a plurality of convex parts is embedded in the grids of the metal heat conduction layer E, and the assembly is completed.
