Embodiment 1

[0033] In this example, the preparation process of the special film electrothermal material for floor heating is as follows:

[0034] First, the multi-layer graphene powder and carbon nanotube powder are mixed in a weight ratio of 1:2, and pre-washed in the reaction kettle through a surfactant, the surfactant is an ethanol solution with a concentration of 90wt% and pure water Mix according to the weight ratio of 1:1, put the mixed powder in the surfactant liquid, soak for 30 minutes and then carry out clarification treatment.

[0035] Then, take the mixed powder that has been pre-washed by the surfactant, put it into a dispersion stirring tank, add an adhesive, and stir at a high speed of 1500 rpm for 30 minutes. At the same time, add dispersants, plasticizers, sprinkling agents and fillers, stir evenly, grind for 30 minutes through a grinder, filter and pack as finished products. When using, dilute the finished product with water in a ratio of 1:3 by weight.

Abstract

The invention relates to the field of manufacturing of electrothermal films and manufacturing of electrothermal products, and particularly relates to a manufacturing process of a graphene nanometer far-infrared negative ion electrothermal film. Biaxially oriented stretching film is coated in front and back sides of a graphene aqueous carbon nanometer electrical heating material layer, a nanometerfar-infrared negative ion ink layer is printed on the oriented stretching film on the front side of the graphene aqueous carbon nanometer electrical heating material layer by a silk screen, and a reflective film aluminum powder ink layer is printed on the oriented stretching film on the back side of the graphene aqueous carbon nanometer electrical heating material layer by the silk screen. The manufacturing process fully utilizes the characteristic that graphene has excellent electrical conductivity and thermal conductivity; multi-layer graphene powder is selected to be combined with carbon nanotube powder; other auxiliary materials and diluents are fully combined, wrapped and added; a conductive heating liquid is prepared by roller grinding and filtration; and after dilution is performed,the electrothermal film can be used for printing and spraying on various substrates to form a conductive heating product.

Description

technical field [0001] The invention relates to the field of manufacturing electric heating films and electric heating products, in particular to a manufacturing process of graphene nanometer far-infrared negative ion electric heating films. Background technique [0002] Since the United States and France's electric heating film entered China in the 1990s, it has promoted the continuous development of my country's electric heating market, and my country's electric heating film has gradually matured. Whether it is metal film, carbon powder film or graphite film, it has been greatly improved. , the usable area is gradually expanding. The market is becoming more and more mature, but the disadvantages brought by the electric heating film are becoming more and more apparent. When the electric heating film in the United States and France entered China, it was strictly forbidden to be installed underground, because with the increase of the service life, The power is constantly atte...
