Abstract

The invention discloses a graphene high molecular heating plate material, which comprises a coating layer, a framework material and a heating wire layer, wherein the coating layer is made of materialsof graphene powder, far infrared powder and resin according to the mass ratio of 1 to (1 to 5) to (100 to 500). The coating layer of the graphene high molecular heating plate material is prepared from the graphene powder, the far infrared powder and the resin. Compared with a conventional heating plate material, the plate material has the advantages of high mechanical intensity, light weight, uniform heating and the like. Meanwhile, after the graphene composite high molecular plate material is excited by current, the heat radiation is mainly performed in a far infrared ray radiation way; farinfrared rays with the wavelength being 4 to 14 micrometers can be released; the absorption by the human body is easy; the human body health is facilitated.

Description

technical field [0001] The invention relates to the technical field of graphene plates, in particular to a graphene polymer heating plate and a preparation method thereof. Background technique [0002] Graphene is a honeycomb planar film formed by sp2 hybridization of carbon atoms. It is a quasi-two-dimensional material with only one atomic layer thickness, so it is also called monoatomic layer graphite. Andre Geim and Konstantin Novoselov, physicists at the University of Manchester in the United Kingdom, successfully separated graphene from graphite by micromechanical exfoliation, so they jointly won the 2010 Nobel Prize in Physics. The common powder production methods of graphene are mechanical exfoliation method, redox method, and SiC epitaxial growth method, and the film production method is chemical vapor deposition (CVD). Due to its very good strength, flexibility, electrical conductivity, thermal conductivity, and optical properties, it has been greatly developed in ...
