Abstract

The invention provides a warmth-keeping room material which sequentially comprises a thin film solar cell panel, an insulating reflection film, carbon nanotube-aramid fiber paper, an insulating heat-conducting film, electromagnetic shielding paper and an insulating heat-conducting film. The carbon nanotube-aramid fiber paper is prepared from carbon nanotube, aramid fiber chopped fiber and aramid fiber fibrid. The carbon nanotube-aramid fiber paper serves as a far infrared reflector of the material, electrothermal radiation conversion rate of the material is up to higher than 90%, vibration frequency of far infrared emitted by the material is close to that of cell molecules in a human body, and resonance generated in the process can increase subcutaneous deep-layer temperature of the humanbody to play a role in warmth keeping. The invention further provides a preparation method of the material. The preparation method is simple and easy to operate.

Description

technical field [0001] The invention relates to the technical field of far-infrared materials, in particular to a heat-preserving room material and a preparation method thereof. Background technique [0002] In the northern part of Heilongjiang Province, the Qinghai-Tibet Plateau, Gansu, parts of Inner Mongolia, and other high-latitude and polar regions, the perennial low temperature makes keeping warm an essential part of every household. For those who need to stay in the wild for a long time, it is necessary There is a place to keep warm and keep out the cold. Common heat preservation and heating methods are coal-fired boilers and electrical heating, etc. However, these methods not only have poor heating effects, but also have low resource utilization rates, resulting in waste of resources. Contents of the invention [0003] The object of the present invention is to provide a far-infrared heating electromagnetic shielding heat-preserving room material and a preparation ...
