The invention belongs to the technical field of infrared electrothermal films, and especially relates to an infrared electrothermal film and a preparation method thereof. The infrared electrothermal film comprises an insulating mounting plate layer and polyimide heating sheet single bodies, arrays formed by polyimide heating sheet monomers are uniformly distributed, adhered and fixed on the top surface of the insulating mounting plate layer. An array composed of plastic pits is evenly distributed on the bottom face of the insulation mounting plate layer, the polyimide heating piece single bodies and the plastic pits are arranged in a one-to-one correspondence mode, through holes are formed in the centers of the plastic pits, and conductive columns are electrically connected to the centersof the polyimide heating piece single bodies. According to the invention, when the surface of the suede layer is pressed or touched, the plastic pits are deformed by pressure. The conductive column iscontacted with the reflection conductive foil. The conductive metal net and the reflective conductive foil are sequentially conducted through the polyimide heating piece single bodies, the polyimideheating piece single bodies emit heat, and the heat is finally conducted to the outside of the current area through the suede layer, so that the directional heating function on the specific area is realized, and the infrared electrothermal film has the advantages of accurate heating area and good heat transfer effect.
Description
technical field [0001] The invention relates to the technical field of infrared electric heating film, in particular to an infrared electric heating film and a preparation method thereof. Background technique [0002] Electric heating film is divided into high temperature electric heating film and low temperature electric heating film. High temperature electric heating film is generally used in electronic appliances, military, etc. The electric heating film heating system is different from the point heating system represented by radiator, air conditioner and radiator, and the heating cable The representative linear heating system is a low-carbon heating high-tech product developed by modern aerospace technology in the field of surface heating. The low-temperature electric heating film is a translucent polyester film that can generate heat after being energized. The metal bus bars are processed and hot-pressed between insulating polyester films. When working, the electric he...
