Heated area element and method for fixing same

The flat element comprises a front side and a rear side, which has a heating layer and a contacting layer, where the heating layer consists of an intrinsically heatable self-adhesive mass (10), which is formed as a conductor heating itself during passing an electric current. The contacting layer is...

Zusammenfassung:	The flat element comprises a front side and a rear side, which has a heating layer and a contacting layer, where the heating layer consists of an intrinsically heatable self-adhesive mass (10), which is formed as a conductor heating itself during passing an electric current. The contacting layer is formed as a contacting element (20) expanded in a flat-shaped manner and broken by notches and has a first side surface and a second side surface. The contacting layer contacts with the heating layer over the first side surface and is electrically conductively connected with the heating layer. The flat element comprises a front side and a rear side, which has a heating layer and a contacting layer, where the heating layer consists of an intrinsically heatable self-adhesive mass (10), which is formed as a conductor heating itself during passing an electric current. The contacting layer is formed as a contacting element (20) expanded in a flat-shaped manner and broken by notches and has a first side surface and a second side surface. The contacting layer contacts with the heating layer over the first side surface and is electrically conductively connected with the heating layer. The second side surface of the contacting layer forms the front side of the flat element. The notches are continuously formed in the contacting element over the thickness of the contacting element and are present in the area of the second side surface in an adhesive-free manner. The intrinsically heatable self-adhesive mass is a positive temperature coefficient (PTC) thermistor. The first side surface of the contacting layer is partially embedded into the intrinsically heatable self-adhesive mass, and lies on a side surface of the intrinsically heatable self-adhesive mass in a flat manner. The thickness of the contacting element is less than 20 mu m. The notches form more than 50% of the surface of the first side surface of the contacting layer or more than 75% of the first side surface of the contacting layer. The broken contacting element has web-shaped areas, which have a width of highly 5 mm or less than 1 mm and are present in a branched comb structure or finger structure. The intrinsically heatable self-adhesive mass comprises an electrically conducting filler material, which comprises graphite, carbon nanoparticles and conductive soot. An independent claim is included for a method for joining a flat element with an adhesion substrate.
