Problems solved by technology

[0003] However, due to the incomplete fit between the heating element and the floor, not only is the installation process complicated and cumbersome, but also the gap between the heating element and the cement layer will cause a large amount of heat loss during the heating process.

preparation example Construction

[0037] Based on the structure of the above-mentioned graphene layered composite floor heating board, the present invention also provides a preparation method of a graphene layered composite floor heating board, comprising the steps of:

[0038] S1, preparation of graphene electrothermal filler;

[0039] S2, preparation of graphene electrothermal coating;

[0040] S3, coating of graphene electrothermal coating;

[0041] S4. Assembly of layered composite floor heating panels.

[0042]Since the graphene electrothermal filler used in the present invention is an electrothermal coating, the electrical conductivity of the coating is mainly improved by the conductive filler with high conductivity, and a small amount of palladium powder is added to the electrothermal coating of the present invention to improve the electrical conductivity of the electrothermal coating , far due to the electrothermal coating composed of a single graphene filler. Preferably, the graphene electrothermal...

Abstract

The invention discloses a graphene layered composite floor heating plate, and belongs to floor heating equipment. The graphene layered composite floor heating plate comprises a base plate, a grapheneelectrothermal filler coating the base plate, an insulating sealing layer for sealing the graphene filler in a glued mode, a metal heat-conducting layer which is fixedly mounted on the insulating sealing layer and is in a grid shape, a floor detachably mounted on the metal heat-conducting layer, honeycomb aluminum filling the metal heat-conducting layer, and an electrode electrically connected with the graphene filler. The graphene layered composite floor heating plate does not need to adopt a polymer compound unstable in insulation and chemical property as an auxiliary substrate, and has thebetter heating effect and longer service life; and in addition, the graphene filler is fixed in a direct coating mode, and thus the graphene layered composite floor heating plate has higher operability and can be set into application scenarios of different circuit structures and the graphene filler according to the requirements.

Description

technical field [0001] The invention belongs to floor heating equipment, in particular to a graphene layered composite floor heating panel. Background technique [0002] The existing central heating method needs to consume a lot of financial and material resources in the installation of the heating system, and the heat loss is relatively serious during the transmission process. Moreover, in most parts of the south, considering the climate, cost and other reasons, it is impossible to use the central heating system as a Heating method. The electric heating system, for example, directly installs electric heating elements (heating cables, carbon crystal panels, and electric heating panels) under the floor for use. The application market in the northern region is gradually expanding. [0003] However, due to the incomplete fit between the heating element and the floor, not only the installation process is complicated and cumbersome, but also the gap between the heating element ...
