Problems solved by technology

The electrothermal film heating system is different from the point heating system represented by radiators, air conditioners, and radiators, and the line heating system represented by heating cables. It is a low-carbon heating technology developed by modern aerospace technology in the field of surface heating. Products, the advantages of graphene electric heating film, such as environmental protection, energy saving, and high cost performance, have been widely promoted, but there are certain problems in the preparation of traditional graphene electric heating film, such as imperfect heating paste, uneven coating and drying, etc. To this end, we propose a production process for graphene electrothermal film

Abstract

The invention discloses a production process of a graphene electrothermal film. The process includes graphene slurry preparation, substrate selection, coating, drying, detection, current-carrying strip lamination, resistance detection, code spraying, and cutting to obtain the graphene electrothermal film. Heat generating slurry of the electrothermal film has good film forming effects, high adhesive force, elasticity, difficult breakage of coatings, and the like. Drying is achieved by two stages which are sizing and drying stages, wherein the slurry after coating is firstly sized and then is dried in a hot wind circulating manner so that the slurry is more uniformly dried, surface thickness is uniform and product quality is improved.
