Abstract

The invention discloses an infrared heating suspended ceiling. The infrared heating suspended ceiling is composed of a conductive layer and an infrared coating layer. And the conductive layer is madeof a carbon-based conductive material and comprises a film formed by spraying a graphene conductive coating, an artificial graphite film, a carbon tube film, carbon fibers, graphene fibers and the like. The infrared coating layer is assembled on the surface of the conductive layer layer by layer through centrifugal spin coating, and the infrared heating suspended ceiling is obtained through curing. According to the infrared coating layer, a polysilicate layer serves as a bottom insulating layer, a silicon carbide layer serves as a middle layer and an insulating layer, a graphitizable polymer layer serves as an upper rivet fixing layer, and spherical graphene penetrates through the three-layer structure. The size of the spherical graphene is 2 to 8 microns, and the total thickness of the three-layer structure composed of a bottom layer, a middle layer and an upper layer does not exceed 1 / 3 of the size of the spherical graphene; the thickness of the upper layer is less than 10 nm. According to the infrared heating suspended ceiling, the heating efficiency is greatly improved, meanwhile, in the field of infrared radiation heating, the comfort of a human body is improved, and meanwhile, the energy consumption is greatly reduced.

Description

technical field [0001] The invention belongs to the technical field of infrared radiation, and in particular relates to an infrared heating ceiling. Background technique [0002] With the development of society, human beings are more and more dependent on energy, but with the gradual consumption of fossil energy, the cost of energy is getting higher and higher. Therefore, it is imminent to use energy more efficiently in human life and production activities. At the same time, people have higher and higher requirements for the quality of production and life. Under the same energy conditions, comfort has become the first choice. [0003] At present, the electric heating equipment in daily life is mainly heat conduction heating equipment such as hot filament and hot oil, which consumes a lot of power and has a small heating range; at the same time, its infrared radiation has a short wavelength and poor human comfort. [0004] Interface heating is mainly the surface heating of h...
