Problems solved by technology

However, the far-infrared radiation emissivity of far-infrared ceramic powder is low, mostly between 0.7 and 0.85
At present, far-infrared materials at home and abroad generally use metal oxides, non-metal oxides and rare earth materials, which have problems such as high cost, complicated preparation process and single function.
At present, the far-infrared materials developed and produced in China have been put into industrial production, but the basic research is not in-depth in general, and the effect is not obvious

Abstract

The invention discloses a bamboo charcoal-tourmaline far IR composite material. The weight percentage of the formula components thereof are as follows: 40 to 60 percent of bamboo charcoal as well as 40 to 60 percent of tourmaline. The invention also provides a preparation method for the composite material, which comprises the following steps: 1) the tourmaline is calcined for 1 to 3 hours at the temperature between 500 and 700 DEG C; 2) the calcined tourmaline and the bamboo charcoal are fully mixed and grinded according to the formula proportion to lead the granularity of the obtained mixed powder to achieve 0.1 to 1um; 3) the mixed powder is shaped under the pressure between 90 and 110MPa and then calcined for 1 to 5 hours at the temperature between 850 and 1000 DEG C under a vacuum environment to obtain a calcined substance; and 4) the calcined substance is cooled to normal temperature to obtain the composite material. The composite material has the characteristic of high far IR transmission rate.

Description

technical field [0001] The invention relates to a far-infrared composite material and a preparation method thereof, in particular to a far-infrared composite material using bamboo charcoal and tourmaline as raw materials and a preparation method thereof. Background technique [0002] Humans discovered far-infrared rays nearly 200 years ago, and explored the industrial and medical applications of far-infrared rays in the past 50 years. Looking around the domestic and foreign markets, the sales of far-infrared functional materials and their products are increasing day by day, and their influence is expanding. They have not only spread among consumers, but also continue to show new development potential. In recent years, with the continuous improvement of people's living standards, not only the requirements for the beautification of the family environment and living space are increasing, but also the health status of the body is becoming more and more important. If more far-inf...
