Abstract

The invention relates to the field of improving an electric heating element, in particular to a graphene nanometer far-infrared anion composite fiber conductive heating film and a preparation method thereof. The conductive heating film is prepared by the plant fiber pulp, graphene powder glue, nanometer bamboo charcoal fiber powder or nanometer far-infrared anion powder through the grinding, mixing, stirring, stir-frying, drying, pressing and winding processes. During preparation, through the steps of grinding, mixing and stirring, the plant fiber is processed by a disc mill into a broom shape so as to be more easily combined with the graphene powder glue, the graphene powder glue is added to mix and stir, and then a fiber dispersant and the nanometer bamboo fiber powder or nanometer far-infrared anion powder are added to stir evenly. According to the invention, the conductive heating film has the characteristic of adjustable surface resistivity, can be used for an antistatic circuit, can effectively release the charge, and also has the functions of far-infrared emission and anion release to play roles both in purifying and disinfecting and in human health.

Description

technical field [0001] The invention relates to the field of improvement of electric heating elements, in particular to a graphene nanometer far-infrared negative ion composite fiber conductive heating film and a preparation method thereof. Background technique [0002] At present, there are far-infrared heating methods such as metals and non-metals on the market. The more popular ones are carbon fiber carbon crystal electric heating products, and their advantages are: stable electrical conductivity, high strength, small specific gravity, thin thickness, easy to use, and planar heating. The disadvantages are: the uniformity of the heating temperature is poor, there are many hot spots, and the temperature difference is large. Although it has been continuously improved, it still cannot get rid of the weakness of uneven distribution of chopped carbon fibers. Contents of the invention [0003] In order to overcome the weaknesses and hidden dangers of the heating film made of ...
