Heat conduction and heat preservation integrated graphene heating film

Abstract

The invention discloses a heat conduction and heat preservation integrated graphene heating film whichcomprises a polymer insulating layer, a heat-conducting silica gel layer, a graphene electric heating layer, a reflecting film, a heat-insulating layer and a protective shell. The graphene electric heating layer is of a broken-line-shaped or wave-shaped structure, heat conduction silica gel layers are arranged in the upper portion and the lower portion of the graphene electric heating layer, a first macromolecule insulating layer is arranged on the upper surface of the upper heat conduction silica gel layer, and a second macromolecule insulating layer, a reflecting film, a heat insulation layer and a protection shell are connected to the lower surface of the lower heat conduction silica gel layer in a glued mode. Compared with the prior art, heat can be concentrated and conducted upwards, and the heat utilization rate of the heating film is increased. The broken-line-shaped or wave-shaped structure of the graphene electric heating layer can increase the heating area and improve the indoor heating rate. The heating film is of an integrated structure, the laying step of the heating film is simplified, meanwhile, the protection shell can support and protect the whole film structure, and the service life of the heating film is prolonged.

Description

technical field [0001] The invention belongs to heating materials and relates to the technical field of graphene heating floor heating, in particular to a graphene heating film with a good thermal insulation structure, which is especially suitable for building heating. Background technique [0002] Since its discovery in the early 21st century, graphene has been considered as a future revolutionary material due to its excellent optical, electrical, and mechanical properties. Based on the excellent electrical and thermal conductivity of graphene, there are more and more heating products using graphene as the heating element in the market. Among them, the development of graphene heating floor heating film is also particularly rapid. Compared with traditional water heating and floor heating systems, graphene heating film heating speed is fast, and the ground temperature can be felt within 30 minutes of power on; in terms of maintenance cost, one time It can be used for a long ...

Problems solved by technology

In the Chinese patent CN107152143A, a construction method of floor heating pavement for wooden floors with graphene heating film is disclosed. In the construction process of floor heating pavement, pre-treatment is required, such as installing the insulation layer and insulation layer in advance, and the pre-treatment heat preservation needs to be checked. effect, resulting in complex construction techniques and high requirements for the technical level of construction personnel

[0004] In view of the above problems, in order to solve the problem of installing the graphene floor heating film on the market, it is necessary to lay the insulation layer and the reflective layer in advance, and each layer needs to be bonded with adhesive tape, resulting in a certain cost for each installation. Time, and the heating film has too fast heat dissipation and insufficient heat preservation ability during use, so that users cannot make good use of heat. We have invented a new integrated structure with good heat preservation and convenient construction. Thermal insulation integrated graphene heating membrane
