Document Type and Number:
WIPO Patent Application WO/2023/033235
Kind Code:
A1
Abstract:
The present invention relates to a planar heating element for a container, the planar heating element having constant temperature characteristics and comprising: a substrate; carbon patterns printed on one surface of the substrate using carbon ink, the carbon patterns being printed in the shape of a long rectangular band at regular intervals in the vertical direction; at least two copper electrodes laminated at regular intervals in the same direction as the carbon patterns; and at least two silver electrodes laminated at regular intervals in the longitudinal and vertical directions of the copper electrodes, wherein the planar heating element exhibits an output of 1,000 to 6,000 W/m2. The carbon ink comprises, with respect to 100 parts by weight of an organic solvent, 0.5 to 3.5 parts by weight of carbon nanotubes, 5 to 10 parts by weight of graphite, 0.01 to 0.5 parts by weight of a silicone-based antifoaming agent, 0.01 to 0.3 parts by weight of an anionic dispersant, 0.2 to 1 parts by weight of a nonionic surfactant, and 20 to 40 parts by weight of a binder resin composed of ethyl cellulose resin and chlorinated polyolefin.
