Aramid fiber far-infrared emitting paper and preparatin method thereof

A preparation method of aramid fiber far-infrared emitting paper, comprising the following steps:

• (1) mixing para-aramid chopped fiber with a disintegrating agent and water, conducting disintegration, cleaning obtained fiber, conducting low-temperature plasma surface treatment, mixing obtained fiber with a dispersant and water, and conducting ultrasonic treatment and pulping sequentially to obtain para-aramid chopped fiber pulp;
• mixing para-aramid pulp fiber with the dispersant and water, and conducting ultrasonic treatment and pulping sequentially to obtain para-aramid pulp fiber pulp;
• and
• mixing the para-aramid chopped fiber pulp and the para-aramid pulp fiber pulp, and conducting shearing to obtain aramid fiber pulp;
• (2) mixing carbon nanotubes with a dispersant and ethanol, and conducting ultrasonic treatment and shearing sequentially to obtain carbon nanotube dispersion liquid;
• and
• (3) mixing the aramid fiber pulp in step (1) with the carbon nanotube dispersion liquid in step (2) and a paper strength agent, conducting shearing, coating obtained mixed pulp onto a single surface of a substrate, conducting solidification and peeling the substrate, and conducting hot press molding on a solidified film to obtain the aramid fiber far-infrared emitting paper, wherein
• there is no limitation on a time sequence of step (1) and step (2).
