Problems solved by technology

[0003] Chinese patent CN109714837A discloses a graphene electrothermal film, which is composed of a first insulating protective layer, a radiation shielding layer, a heating layer, a reflective heat insulating layer and a second insulating protective layer, and the heating layer is printed on a graphene heating sheet It is composed of a conductive circuit. From the analysis of the public information, it is impossible to form a sheet by spraying only the slurry consisting of graphene powder, conductive carbon powder, carbon nanotubes, conductive amalgam and far-infrared mineral materials. Even if the sheet material base material is selected in addition, it is difficult to realize the printing of the conductive circuit on the sprayed layer because there is no solidified material in the composition, so from the published data, the heating layer cannot realize its heating purpose and the the desired technical effect
In this patent, polyimide resin is selected as the insulating layer, but it is not clear whether it has bonding properties
The aluminized polyimide film also has no bonding performance, how the four layers are bonded together, and the processing technology of how the four layers are bonded together is not clear. The patent disclosure is not sufficient, the disclosure content is vague and unclear, and the purpose of the invention cannot be achieved

Abstract

The invention discloses a thin film heating module and a production method, which comprises the steps of adopting a conductive heating polyimide film, laying a copper foil electrode on the conductive heating polyimide film, the copper foil electrode and the conductive heating polyimide film Fill the polyimide bonding resin through the mesh holes to firmly fix the copper foil on the conductive heating polyimide film; and on both sides of the conductive heating polyimide film covered with copper foil electrodes Lay heat-pressed insulating packaging layers in the form of a sandwich, lead out wires on the copper foil electrode welding, and encapsulate insulation at the welding place. This kind of film heating module completes the overall insulating package, electrification, heating and high temperature resistant module form, and the copper foil electrode and the conductive heating polyimide film have close comprehensive contact, ensuring the electrical contact between the two It has good thermal radiation effect and good insulation, and this kind of film heats up quickly, has a large heating area, uniform heating temperature, high thermoelectric efficiency, and is safe to use.

Description

technical field [0001] The invention relates to a thin film heating production technology, in particular to a thin film heating module including a hard heating module or a flexible heating module and a production method thereof. Background technique [0002] Chinese patent CN101699920B discloses a method for preparing a polyimide heating film. This polyimide heating film uses nano-conductive metal powder and nano-conductive carbon powder to polymerize with polyimide resin to prepare a conductive film. Print on the film or directly use conductive copper foil as the positive and negative electrodes, and then compound polyethylene terephthalate or polyetheramide or polyimide insulating film on both sides of the conductive film for protection. In this patent application, conductive metal powder is used in the heating film, and it is not clear whether there is a conductive adhesive or no conductive adhesive between the copper foil and the heating film. It is not clear how to bon...
