Problems solved by technology

[0003] However, in the past, the heating temperature of the planar heating element is difficult to reach 83°C, and the application is limited, and the insulating film materials that can be used are also limited. When the temperature is higher than 65°C, the insulating film will bulge, which will damage the appearance and performance of the planar heating element.
[0004] In addition, the previous planar heating element is not wrinkle-resistant. Once the insulating film is wrinkled, current collection will occur at the wrinkle interface, which will easily induce cremation, posing fire and power failure hazards.

Abstract

A method of utilizing carbon fiber to prepare planar heating body includes using extremely fine carbon fiber in 5-25mm long and 20micro-100micro thickness, paper pulp, water soluble adhesive ( WSA ) and water to prepare primary paper; using carbon powder on 3-50wt.% of primary paper, conductive polymer in 2-30wt.% of primary paper, WSA and water to prepare carbon powder mixed liquid; preparing silver electrode wire and copper electrode wire after coating said polymer and mixed liquid on primary paper; melting insulation material on planar heating base body said electrode wires then drying it to form insulation layer for obtaining final product.

Description

technical field [0001] The invention relates to a method for manufacturing a planar heating element, in particular to a method for manufacturing a planar heating element using ultra-fine carbon fibers. Background technique [0002] In the past, the method of manufacturing a planar heating element was to mix carbon powder and adhesive and print it on a PET (polyester) film in a certain pattern, and then use polyester film or EVA and other hot-melt adhesives for insulating bonding to form a surface. Shaped heating element. [0003] However, in the past, the heating temperature of the planar heating element is difficult to reach 83°C, and the application is limited, and the insulating film materials that can be used are also limited. When the temperature is higher than 65°C, the insulating film will bulge, which will damage the appearance and performance of the planar heating element. . [0004] In addition, the previous planar heating elements are not wrinkle-resistant. Once...
