Title:
PLANAR HEATING COMPOSITE SHEET
Document Type and Number:
WIPO Patent Application WO/2022/045473
Kind Code:
A1
Abstract:
The present invention relates to a planar heating composite sheet, which consists of: a planar heating layer comprising a base sheet made of a synthetic resin material and having a width and a length, a plurality of electrodes applied to the upper surface of the base sheet along a width direction of the base sheet such that different polarities are alternately arranged and spaced apart from one other along a length direction of the base sheet, a conductive paste applied overall between the plurality of electrodes on the upper surface of the base sheet and generating heat by electrical resistance, and an insulation sheet made of a synthetic resin and attached to an upper part of the conductive paste; and a heat insulating layer comprising a heat insulating sheet attached to a lower part of the planar heating layer and impregnated with aerogel in a nonwoven fabric made of a synthetic resin material, and a protective sheet made of a synthetic resin material and attached to a lower part of the heat insulating sheet.
