Problems solved by technology

[0003] Cable heating technology and electrothermal film technology are also gradually used in the heating field. Compared with the current electric heating film technology, the initial investment of cable heating technology is also large, and the construction is troublesome; while the electric heating film technology takes too long to warm up and heats up. The power is limited, and there are certain restrictions on the application

Abstract

Disclosed is a manufacture method for a flexible large-area high-heat-power electrothermal film. The electrothermal film comprises a conductive film, a copper electrode and an insulation film protective layer. The electrothermal film is prepared by use of a carbon black / silicone rubber conductive composite material. The film has the advantages of flexibility and large area; the electrothermal film has the advantages of uniform heating and high heat power after being energized; and the electrothermal film is in the shape of a large-area film, has the advantages of large heat dissipation area and good heat-transfer property and can be fully contacted with a heated body for heat transfer. The electrotehrmal film provided by the invention can be used for indoor heating in a building and has the advantages of simple installation, relatively low initial investment, rapid heating and the like, thereby having a certain application value.

Description

technical field [0001] The invention relates to the field of electric heating, in particular to a large-area electric heating film heating technology. Background technique [0002] At present, there are many materials and methods that can be used for electric heating. According to the different ways of electric energy conversion, electric heating is usually divided into resistance heating, induction heating, arc heating, electron beam heating, infrared heating and medium heating. At present, the electric heating methods used for building indoor heating mainly include the use of heating cables arranged in the concrete under the floor or carbon fiber mixed into the cement mortar to make it conductive to obtain electric heating performance. This technology is still mainly in the research stage; At present, the electrothermal film appearing on the market is made of conductive special ink and metal current-carrying strips, which are processed and hot-pressed between insulating po...
