Abstract
The present invention relates to a PTC (Positive Temperature Coefficient) element manufactured using a polymer aqueous emulsion conductive composite, and a planar heating element using the same. By controlling electric connection of the heating element using the PTC element, it is possible to control a heating temperature of the heating element to be in a desired range and to improve stability of the heating element. It is easy to manufacture the PTC manufactured using the polymer aqueous emulsion conductive composite, and PTC characteristics thereof can be satisfactorily kept even in use for a long period. Since the planar heating element manufactured using the PTC element has a self temperature control function, a separate temperature control device is unnecessary, which is economical.
A manufacturing method of a PTC element includes: (1) producing a polymer aqueous emulsion solution; (2) producing a polymer aqueous emulsion conductive composite by mixing the polymer aqueous emulsion solution with a conductive agent; and (3) producing a PTC element by coating or dipping and drying a substrate with the polymer aqueous emulsion conductive composite. The polymer aqueous emulsion solution includes an adhesive polymer, a cross-linking agent, an initiator, and water. The substrate is film, non-woven, textile, inflexible plate, and the like, which are formed of polymer resin. A planar heating element is manufactured by attaching electrodes to the PTC element, and laminating an insulating coating material on upper and lower faces of the PTC element.
