Heat-transfer flame-retardant graphene heat-conducting plate and preparation method thereof

Abstract

The invention discloses a heat-transfer flame-retardant graphene heat-conducting plate which comprises a bottom layer, a supporting layer and a surface decoration layer, the supporting layer is located between the bottom layer and the surface decoration layer, and a heating component is arranged in the supporting layer. The heating component is flatly laid at the bottom of the supporting layer andplaced on the supporting table structure of the supporting layer in an overhead mode or arranged on the inner wall of the side face of the supporting layer in an attached mode, the heating componentis a graphene heating film, and the decoration layer is fixedly placed above the top of the supporting layer. The supporting layer with the bearing function is designed, the supporting layer is prepared from the light-weight and high-strength fiber reinforced resin composite material, the mechanical property is excellent, the bearing requirement can be met, the graphene heating film placed in thesupporting layer is well protected, and the graphene heating film is prevented from being displaced due to stress. The plate is high in safety, high in heat transfer efficiency and convenient to install, a plurality of plates can be laid and used through splicing, later repair and maintenance are facilitated, the service life of the whole plate is long, and the plate has wide application value andpopularization space.

Description

Technical field: [0001] The invention belongs to the technical field of heat conduction plates, and in particular relates to a heat transfer and flame-retardant graphene heat conduction plate and a preparation method thereof. Background technique: [0002] With the improvement of people's living standards, in the cold winter, more and more people choose to use heating systems in residential, office and other fields, and put forward the safety, comfort, non-drying, low cost and other aspects of the heating system. higher requirements. At present, the commonly used heating methods include water heating and electric heating. Among them, water heating uses pipes for heat transfer. There are often problems of water leakage caused by corrosion and rupture of pipes, and the heat conduction efficiency is low. To achieve a comfortable temperature , it takes more than ten hours, or even two or three days; electric heating is to lay heating cables or electric heating film on the floor...

Problems solved by technology

The patent "A Graphene Thermally Conductive Floor" (Patent No. ZL201920740314.3) discloses a graphene thermally conductive floor, which mainly includes a bottom moisture-proof layer, a heat-insulating layer, a heat-generating layer, and a heat-conducting layer. There are supporting devices evenly arranged between the graphene heating sheets, which makes the graphene thermally conductive floor have a certain bearing capacity. The heat transfer performance will reduce the heat conduction efficiency to a certain extent

According to the analysis and development of the existing technology, the current design of the graphene heat conduction plate is to select the structure and material separately on the basis of considering a single function, which cannot make the obtained graphene heat conduction plate have both high-efficiency and rapid heat transfer. The two functions of transmission and good carrying capacity limit its large-scale promotion and application in the heating field
