Preparation method of graphene heating plate

Abstract

The invention relates to the technical field of graphene heating plate preparation, in particular to a graphene heating plate preparation method which comprises the steps that a cement foaming plate is selected as a panel base material, fire-resistant and wear-resistant coatings are attached to the front end and the rear end of the cement foaming plate through a film covering device, and then the rear portion of the cement foaming panel is fixedly connected with a metal heat dissipation plate through screws; the rear end of the metal heat dissipation plate is sprayed with a graphene heating layer, the rear end of the graphene heating layer is provided with an electrode plate, finally, the outer side of the graphene heating layer and the outer side of the electrode plate are sequentially wrapped with an insulating layer, a lower light film and a PCB heat insulation film from inside to outside, and the outer side of the PCB heat insulation film is sleeved with a PC/ABS alloy shell. The fireproof and wear-resistant layer is matched with the cement foaming plate to isolate most of heat, so that the heat dissipation plate can only feel slight heat on the surface in the use process, meanwhile, the wear-resistant and heat-resistant performance is high, most of heat in the device is dissipated through the ventilation grooves, and use is safer and more stable.

[0002] Graphene is a sp 2 Graphene is a new material in which hybridized carbon atoms are tightly packed into a single-layer two-dimensional honeycomb lattice structure. Graphene has excellent optical, electrical, and mechanical properties. It is widely used in materials science, micro-nano processing, energy, biomedicine, and drug delivery. It has important application prospects and is considered to be a revolutionary material in the future. Graphene heating panels are mainly used in various heating scenarios such as wall heating, floor heating, heaters, sauna rooms, and pedicure buckets. The benefits of graphene heating panels are as follows: High power density, instant heating, efficient heating, uniform heating, far-infrared heating, acid and alkali resistance, waterproof, no radiation, and high safety. Most of the graphene heating panels currently on the market are in use When the heat is directly dissipated to the surface for heat dissipation, in the process of use, if the temperature of the heating plate is high, it may cause harm to the surrounding users. Therefore, a method for preparing a graphene heating plate is proposed to solve the above problems
