Abstract
The embodiment of the invention discloses a graphene heating sheet and a manufacturing process thereof, which are used for solving the technical problems that the temperature rise speed of the heating sheet is slow and the use requirement of a user cannot be met due to the fact that most of the existing heating sheets adopt metalalloy as a heating body. The heating device comprises a metal sheet, a graphene heating layer is arranged on the first surface of the metal sheet, and a heat insulation layer is arranged on the second surface of the metal sheet; the graphene heating layer is formed by coating and drying graphene heating slurry, and the graphene heating slurry comprises the following components: organic silicon resin, a conductive agent, graphene, a first dispersing agent, a first defoaming agent, a flatting agent and a wetting agent; and the heat insulation layer is formed by coating and drying heat insulation slurry.
Description
technical field [0001] The invention relates to the technical field of heating sheet design, in particular to a graphene heating sheet and a manufacturing process thereof. Background technique [0002] In winter, due to the influence of temperature, people usually hope to maintain the human body in a warm environment by means of heating tools, so as to ensure the performance of daily activities. Therefore, people generally use products with heating functions, such as heating pads, heating clothes, heating gloves, and heating underwear. [0003] In the above-mentioned products with heating function, a heating sheet is set inside as a heating source. The heating sheet in the prior art generally adopts a metal alloy (such as nickel-chromiumalloy, iron-chromium-aluminum alloy) as a heating element. When the heating sheet is energized, The metal alloyheating element inside the heating element will gradually generate heat, and then heat up to the target temperature, but the hea...
