Abstract

The invention provides a flexible heating thick-film element comprising a four-layer structure which comprises a base-layer flexible matrix at the first layer, a rigid carrier at the second layer, thick-film coating coated on the rigid carrier at the third layer and a top-layer flexible matrix at the fourth layer, wherein a thickness ratio of the four layers is that rigid carrier : thick-film coating : top-layer flexible matrix is equal to 70-200 : 3-10 : 1 : 3-70; the thick-film coating is 10-50 microns thick; and the overall thickness of the flexible heating thick-film element is 1-3.5mm. According to the element provided by the invention, the characteristic that the base-layer flexible matrix and the rigid carrier are combined is used, so that within the selection range of bending strength of the element, the adhesion of a thick-film coated on the carrier is ensured, and thus the element generates heat stably, and the whole element can also be flexible, thus being good in flexibility when the element is applied to clothes or other products.

Description

technical field [0001] The invention belongs to the field of thick film heating, in particular to a flexible heating thick film element. Background technique [0002] Thick film heating element refers to a heating element that makes a thick film of heating material on the substrate and conducts electricity to generate heat. At present, there are many researches on thick film paste, but there are few researches on providing flexible heating elements with good heating effect and better flexibility. [0003] CN101193750B discloses a film-laminated polyimide film and a flexible printed circuit board, specifically disclosing a polyimide film with a crimp of no more than 10% after heat treatment at 300°C as the base film, and on the base film Form a film layer by dry electroplating, and form a thick metal film layer on the metal film layer by wet electroplating. The film layer can be a metal film layer or a non-metal film layer. A high dielectric layer with a dielectric constant...
