MANUFACTURING METHOD OF CALORIFIC PAD AND THEREBY HEATING SEAT

摘要

Disclosed is a method for manufacturing a calorific pad using a surface heating element and a heating seat thereby. The method for manufacturing the calorific pad using the surface heating element according to the present invention a step for preparing a first substrate by forming a haze on one side of a first film type substrate, coating an adhesive organic solvent on the one side of a first film type substrate, and printing an electrode; a step for preparing a second substrate by forming a haze on one side of a second film type substrate, coating the adhesive organic solvent on the one side of a first film type substrate, and printing the surface heating element; and a step for bonding the first substrate to the second substrate. The surface heating element includes a step for bonding a functional group to a carbon material in an acidic solution by performing a ultrasonic process; a step for pulverizing the carbon material by dispersing the carbon material having the functional group by performing the ultrasonic process to constantly induce the direction of a current flowing through the dispersed carbon material; and a step for mixing the pulverized carbon material with a high molecular compound. According to the present invention, the method for manufacturing the calorific pad improves heat efficiency and reduces the change of resistance.
