Abstract
The present invention discloses a graphene electrical heating body preparation method. The method comprises the following steps: (1) preparing electrical heating body slurry; (2) preparing silver electrode; (3) preparing an electric heating layer; and (4) preparing an encapsulated layer. The electrical heating body prepared by the graphene electrical heating body preparation method employs the graphene electrical heating slurry, and because the minimal current can activate a grapheme far-infrared electrothermal portion, the graphene electrical heating body preparation method only save 60% of energy compared with a traditional electrothermal mode, and therefore, the electric energy utilization rate is improved, the heat transfer resistance is small, and the chemical stability, the heat stability and the electrothermal conversion efficiency are high. The number of the printing silk screens, the number of times of printing sintering and the number of times of continuous printing are combined to realize the changing of the total resistance value of a fixed figure so as to reach an object restistance.
