Abstract: A method of manufacturing an activated carbon fiber soft electric heating product for overcoming existing problems including uneven temperature rise and heat dissipation at surfaces of the product, unbendable feature, short life and poor safety. An activated carbon fiber cloth and a woven fiber cloth of the activated carbon fiber soft electric heating product are fixed by an epoxy resin layer, and a conducting copper net is disposed between the activated carbon fiber cloth and the epoxy resin layer and coupled to a power input wire. The manufacturing method includes the steps of: (1) spraying an epoxy resin on a surface of the woven fiber cloth, and bake-drying and hot pressing the woven fiber cloth; and (2) connecting the conducting copper net and the power input wire, laying the activated carbon fiber cloth, and performing a second-time hot pressing.

Abstract: The present invention discloses a nano carbon crystal material and a method of manufacturing electrothermal board using the same, which is a crystal material and a method of using the facial heat generating body to overcome the present existing problems related to even temperature rise and heat dissipation at the surface of the carbon fiber electrothermal board, poor contact between the carbon fiber and the conducting band, poor insulation, and short life expectancy. The nano carbon crystal material is composed of acrylonitrile-based carbon fibers occupying 70˜80% of the total weight, nano carbon fibers occupying 1˜5% of the total weight and carbon crystals occupying 15˜29% of the total weight. After the nano carbon crystal material is mixed with a paper pulp and an adhesive is added, the electrothermal board produced under pressurized conditions will have the advantages of high stability, fast temperature rise, good insulation, and long life.
