Problems solved by technology

At present, the application of carbon nanotubes to emit far-infrared rays is usually to coat carbon nanotubes on a finished film (such as a plastic film). There will be a large energy loss at the recombination between them, and the characteristics of the material itself cannot be fully exerted
Therefore, the far-infrared emissivity of the composite material obtained by this method is low, which seriously restricts its further application.

Abstract

The invention provides a preparation method for aramid fiber far infrared emission paper. In the preparation method, para-aramid chopped fibers and para-aramid pulp fibers are used as a paper base function material, the paper base function material has the excellent characteristics of high specific strength and large specific stiffness; and the para-aramid chopped fibers and the para-aramid pulp fibers can form a paper-like object (an aramid fiber layer) with a grid structure, the grid structure of the paper-like object is filled with carbon nano tubes, and the carbon nano tubes can be tightlycombined with the aramid fiber layer through hot press molding, so the obtained aramid fiber far infrared emission paper has the better molding quality and compounding performance. A result of an embodiment shows that a far infrared emissivity of the aramid fiber far infrared emission paper provided by the method reaches 90%, the aramid fiber far infrared emission paper can bear 300 g of a weightand cannot be crushed.

Description

technical field [0001] The invention relates to the technical field of far-infrared emitting materials, in particular to an aramid fiber far-infrared emitting paper and a preparation method thereof. Background technique [0002] Far infrared is a kind of light wave located in the infrared wavelength range. Its wavelength is in the range of 3 ~ 100 μm, and it is often not noticed by people. However, far infrared has a very important effect on the living body. After the human body absorbs far infrared, the body temperature rises , telangiectasia, active blood circulation, in order to enhance the body's metabolism and the operation of the body. The excellent performance of far-infrared rays makes it more and more widely used in the fields of life science and biomedicine. At present, there are only a small number of devices capable of emitting far-infrared rays, but due to the limitation of the nature of materials used to emit far-infrared rays, the far-infrared rays emitted by...
