Abstract

The invention discloses a graphene material used for hot compress materials and a preparation method thereof, belonging to the technical field of hot compress materials. The product developed by the present invention comprises a graphene layer and a PET resin layer composite material; the composite material is a sandwich structure, and the upper and lower outer surfaces of the sandwich are PET resin layers; the sandwich structure is a PET resin layer-graphene layer- The PET resin layers are arranged in sequence; the nano-silicon compound is embedded between the graphene layers; the nano-silicon compound connects two adjacent graphene sheet structures through Si-C chemical bonds; the nano-silicon compound is at least partially distributed in the graphite ene defect structure. When preparing the product, the graphene is first processed, then the graphene, the binder and the solvent are mixed and dispersed, and then coated on the surface of the PET film, so that a sandwich structure is formed reciprocally. The invention can effectively eliminate the defect structure caused by the graphene material in the preparation process, and improve the structural stability of the product.

Description

technical field [0001] The invention relates to the technical field of thermal compress materials, in particular to a graphene material used for thermal compress materials and a preparation method thereof. Background technique [0002] Compared with traditional thermoelectric materials (nickel-chromium alloys, iron-chromium-aluminum alloys, and conductive ceramics), graphene has the advantages of high flexibility, low density, uniform heating, and high electrothermal conversion efficiency. Moreover, graphene will emit far-infrared light waves with a wavelength of 6-15 μm in a heating state, and the thermal radiation efficiency can reach 90%. Infrared rays in this band are called "light waves of life", which can improve blood circulation, enhance metabolism, and have good anti-inflammatory and analgesic effects. Arthritis, lumbar muscle strain, bone hyperplasia and other diseases have a higher and higher incidence rate with the improvement of living standards and the increas...
