Description

technical field [0001] The invention relates to the field of heat-conducting inks, in particular to a far-infrared heat-conducting slurry and its preparation method and application. Background technique [0002] Carbon-based heat-conducting ink has good adhesion on phenolic paper board, epoxy glass fiber board, polyethylene terephthalate (PET) film board and flexible board, and has excellent printability, heat resistance and moisture resistance 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. 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 8-15 μm far-infrared light, which produces far-infrared radiation, which is easy for the human body to absorb and beneficial to the human body. Healthy, able...
