Abstract

The invention provides an electrothermal film and a production process thereof, belongs to the technical field of heating, and solves the problems of poor heating effect and low production efficiency of an existing electrothermal film. The electrothermal film comprises an upper PET (polyethylene terephthalate) film and a lower PET film, wherein a plurality of copper bars are arranged between the upper PET film and the lower PET film; upper nonwoven cloth and PVC (polyvinyl chloride) films are arranged between the upper PET film and the copper bars in sequence; lower nonwoven cloth and heat-conducting layers made of carbon paste are arranged between the lower PET film and the copper bars in sequence; the copper bars are arranged between the heat-conducting layers and the PVC films. The electrothermal film has the advantages of good softness, convenience for construction and good heating effect.

Description

technical field [0001] The invention belongs to the technical field of heating, and relates to an electric heating film. Background technique [0002] The electrothermal film is a translucent polyester film that can generate heat after being energized. It is made of conductive special ink and metal current-carrying strips, which are processed and hot-pressed between insulating polyester films. When working, the electric heating film is used as the heating body, and the heat is sent into the space in the form of radiation, so that the human body and objects are warmed first, and its comprehensive effect is better than the traditional convection heating method. The low-temperature radiation heating film system consists of a power supply, a temperature controller, connectors, an insulating layer, a heating film and a finishing layer. [0003] With the development of smart homes, electrothermal films are more and more applied to smart buildings, but the current existing electro...
