Graphene-based far infrared electrothermal film without coated printing

Abstract

The invention relates to the technical field of electrothermal films, in particular to a graphene-based far infrared electrothermal film without coated printing. The film comprises an electric conduction layer, wherein two sides of the electric conduction layer are independently compounded and spliced with a synthesis layer; the lower surfaces of the synthesis layers are spliced with a lower insulated protection layer; the lower surface of each metal electric conduction current carrying bar is also spliced with a current carrying bar splicing layer; the lower surface of the current carrying bar splicing layer is also compounded and spliced with an upper insulated protection layer; and the upper insulated protection layer and the lower insulated protection layer are in same arrangement. Byuse of the film, the problems in an existing electrothermal film processing technology that a coated printing effect is not ideal, power density is uneven and the like can be solved. The graphene-based far infrared electrothermal film without coated printing is reliable in fastness, does not layer and solves an oxidization problem in the prior art. The use safety performance of the electrothermalfilm is improved, pressure for environment protection by the prior art can be alleviated, energy saving and emission reduction are realized, and in addition, a processing technology is convenient.

Description

technical field [0001] The invention relates to the technical field of electric heating films, in particular to a graphene-based far-infrared electric heating film without coating and printing. Background technique [0002] With the disadvantages of traditional heating methods becoming more and more prominent, electrothermal film heating is more and more favored by consumers for its safety, comfort, energy saving, environmental protection, health and many other advantages. Different conductive substances and film-forming substrates can form many kinds of electrothermal films. According to the "Low Temperature Radiation Electrothermal Film" (JG / T286-2010) construction industry industry standard issued by the country in 2011, according to the different heating elements, low temperature radiation electrothermal films are divided into There are three types of metal-based electric heating films, inorganic non-metallic electric heating films (including printing ink electric heatin...

AI Technical Summary

Problems solved by technology

Due to the complex process and high cost, it will affect environmental protection and increase the pressure of national environmental protection, and there are problems such as unsatisfactory peel strength and difficult control of printing quality. The coated silver paste electrodes are easily oxidized. Due to repeated thermal expansion and contraction, tiny cracks will appear, which will greatly reduce the product life, cause safety hazards, and even lead to fire accidents, which also has a negative impact on the development of the electric heating film industry.
