Problems solved by technology

In related technologies, most electrothermal inks are used under the condition of 220V high voltage, and the safety voltage of the human body is below 36V. Direct contact with high working voltage products will bring certain safety hazards to users. In addition, there is also thermal attenuation Problems such as large size, high cost, and easy moisture absorption of the film layer affect the thermal stability and service life of the product

Abstract

The invention provides an electrothermal ink with low working voltage and high far infrared radiance, and a preparation method thereof, wherein the electrothermal ink comprises, by mass, 5-20% of three-dimensional graphene, 1-10% of two-dimensional graphene, 1-5% of carbon nano-tubes, 5-20% of electric-conduction carbon black, 15-45% of a resin binder, 15-30% of a solvent, 1-10% of a dispersant, and 0.5-5% of an auxiliary agent. According to the present invention, the three-dimensional graphene, the two-dimensional graphene, the carbon nano-tubes and the electric-conduction carbon black can form a synergistic effect, such that the obtained electrothermal ink can work under a safe voltage of less than 36 V while meets the electrothermal performance standard, and further has advantages of high far-infrared radiation rate, safety, environmental protection, stable electrothermal performance and oxidation resistance; and the preparation method is simple, and is suitable for batch preparation.

Description

technical field [0001] The invention relates to the technical field of electrothermal materials, in particular to an electrothermal ink with low operating voltage and high far-infrared emissivity and a preparation method thereof. Background technique [0002] In recent years, with the implementation of the national "coal-to-electricity" policy, electric heating products that can be heated and have far-infrared physiotherapy effects have gradually entered our lives, allowing people to have a comfortable experience. Electric heating products cover a wide range of fields and types, such as low-temperature electric heating film, electric heating painting, intelligent heating clothing, heating carpet, etc. In electric heating products, the electric heating material is the key technology. According to the heating principle, the electric heating material can be mainly divided into resistance wire and electric heating ink coating. Among them, the electric heating ink coating belongs...
