preparation example Construction

[0024] The invention provides a kind of preparation method of far infrared paper, comprises the following steps:

[0025] (1) mixing the dispersion of para-aramid chopped fibers and the dispersion of para-aramid precipitated fibers, and beating to obtain aramid fiber slurry;

[0026] (2) mixing the aramid fiber slurry with a reinforcing agent, followed by papermaking, drying and rolling to obtain an aramid insulating paper;

[0027] (3) Mix the aramid fiber slurry with the dispersion of carbon nanotubes and a reinforcing agent, absorb the gained aramid-carbon nanotube fiber slurry onto filter paper, and sequentially dry, roll and peel off the filter paper to obtain Aramid-carbon nanotube paper;

[0028] (4) Laminating the aramid insulating paper and aramid-carbon nanotube paper into a sandwich structure with aramid-carbon nanotube paper as the core layer and aramid insulating paper as the surface layer, and performing hot pressing to obtain far-infrared paper.

Abstract

The invention provides far-infrared paper. The far-infrared paper has a sandwich structure; a surface layer of the sandwich structure is aramid insulating paper, and a core layer of the sandwich structure is aramid-carbon nanotube paper. The far-infrared paper is used for an electric heating device, and the obtained aramid far-infrared physiotherapy electric heating device has uniform heating, adjustable power and high electrothermal conversion efficiency (close to 100%), can save energy, has physical therapy, warming and health-preserving functions and the like, and can meet the needs of different users.

Description

technical field [0001] The invention relates to the technical field of heating physiotherapy equipment, in particular to a far-infrared paper and a preparation method thereof, and an aramid far-infrared physiotherapy electric heating device. Background technique [0002] With the improvement of people's living standards, the issue of heating has always received great attention, especially in winter and in cold northern cities. Heating is not only about keeping away from the cold, but also about comfort and health. At present, most of the heating equipment used are electric floor heating devices, which heat the floor or tiles through heating cables, and control the room temperature or floor temperature with a thermostat to realize the heating method of floor radiation heating. However, the above-mentioned heating method not only provides uneven heating, low electrothermal conversion efficiency, and wastes electricity, but also the long-term heat dissipation of this method wil...
