Abstract (en)

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 70ˆ¼80% of the total weight, nano carbon fibers occupying 1ˆ¼5% of the total weight and carbon crystals occupying 15ˆ¼29% 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. In addition, the method of manufacturing the electrothermal board is simple, easy, and convenient, and thus is suitable for mass production to satisfy the requirements of production as well as our daily life.
