Problems solved by technology

[0004] However, the carbon-based electrothermal ink of the prior art, after being energized, at a certain temperature, the far-infrared radiation rate is not high enough, the effect on the human body is weak, the effect of physical therapy and health care is low, and the temperature required to produce far-infrared radiation is relatively high. Generally, it needs to be above 150°C to have strong radiation, and it does not have the ability to release hydroxyl anions (H 3 o 2 - ), antibacterial, antibacterial and air purifying functions

Abstract

The invention provides a far-infrared carbon composite electric heating ink, and a preparation method and application. The far-infrared carbon composite electric heating ink provided by the invention comprises the following components by mass percent: 1-20% of composite oxide powder, 1-5% of diluent and 75-98% of carbon electric heating ink. The far-infrared carbon composite electric heating ink prepared by the method has an enhanced electric heating function; an ink system is uniform and stable, and can be applied to a far-infrared electric heating product with the enhanced electric heating function.

Description

technical field [0001] The invention relates to an ink technology, in particular to a far-infrared carbon-based composite electrothermal ink and its preparation method and application. Background technique [0002] Carbon-based electrothermal ink has good adhesion on phenolic paper board, epoxy glass fiber board, polyethylene terephthalate (PET) film board and flexible board, and has excellent printability, durability Heat resistance, moisture resistance and stable heat generation, so it is widely used in far-infrared drying ovens, incubators, electric blankets, sauna rooms, circuit boards, electric floor heating panels and greenhouse electric heating and other fields. [0003] At present, in the application of carbon-based electrothermal ink in far-infrared radiation, the principle is that when the carbon-based electrothermal ink is energized, the carbon powder emits far-infrared light of 8-15 μm to generate far-infrared radiation, and the spectrum of 8-15 μm Approximating...
