Problems solved by technology

For example, biochar and carbon fiber products need to be energized or heated to produce far-infrared rays; tourmaline, far-infrared ceramics and products use natural ore as raw materials, and the components in the ore fluctuate, so the far-infrared release performance of the product also fluctuates Jade has fewer sources and is more expensive; while metal oxides and silicon carbide also need to be able to release far-infrared rays under the condition of higher than 150 ° C, and the application range is also limited.

Embodiment 1

[0030] The high surface area far-infrared material is prepared by the following process,

[0031] 1) Mixing and crushing of raw materials

[0032] Get 75g of aluminum oxide, 10g of iron oxide, 1g of zinc oxide, 5g of cobalt oxide, 4g of nickel oxide, 2g of manganese oxide, and 3g of copper oxide according to the weight percentage of raw materials, and put them in a ball mill for ball milling. The ball mill speed for mass production is 600 revolutions per minute. Maintain for 4 hours, the output particle size is 5-10 microns, and the mixed fine material is obtained.

[0033] 2) Sintering

[0034] The mixed fine material is sintered, the sintering temperature is increased by 5°C per minute to 800°C, and the time is maintained at 800°C for 4 hours, and the high surface area far-infrared material can be obtained.

Embodiment 2

[0035] Embodiment 2, basic process is the same as embodiment 1, but formula is aluminum oxide 80g, iron oxide 10g, zinc oxide 1g, cobalt oxide 4g, nickel oxide 2g, manganese oxide 2g, copper oxide 1g.

Embodiment 3

[0036] Embodiment 3, the basic process is the same as that of Embodiment 1, but the rotating speed of the ball mill is 400 rpm, maintained for 6 hours, and the sintering temperature is increased by 3°C per minute to 900°C, and maintained at 900°C for 2 hours.

[0037] Adopt embodiment 1 gained high surface area far-infrared ray material to carry out essential oil adsorption test, test method and result are as follows:

[0038] Take this material and 10 grams of ordinary alumina and place them in the same plastic container. After putting them in, scrape the materials flat, and then slowly add sandalwood essential oil to determine the adsorption amount by the incipient wetness method (stop adding essential oils when the surface of the material is just wet) . Results The high specific surface area far-infrared material adsorbed 9.52 grams, while the general alumina was 2.35 grams.

[0039] The results show that this material has good adsorption properties for essential oils.

Abstract

The invention relates to a high surface area far infrared material, and a preparation method and applications thereof. The components of the material and the contents of the components in weight percent are as follows: 50-92% of alumina, 2-20% of iron oxide, 0.1-5% of zinc oxide, 2-20% of cobalt oxide, 1-10% of nickel oxide, 0.1-10% of manganese oxide, and 0.1-5% of copper oxide. The preparation method comprises the following steps: 1) placing raw materials in a ball mill for ball milling with a discharging-material size of 5-10 micrometer to obtain a mixed fine material; and 2) heating to a temperature of 600-1000 DGE C at a heating rate of 3-6 DEG C / min and sintering the mixed fine material for two hours. The material of the invention is advantageous in that: 1) the far infrared rays releasing performance is stable; 2) the specific surface area is high and the adsorptive property is good; 3) the drug absorption process is turned into a active release process when the material is used as excipients for medical external preparation, therefore improving the drug absorption speed; 4) the preparation method is simple.

Description

technical field [0001] The invention relates to the technical field of chemical materials, in particular to a high-surface-area far-infrared material and its manufacturing method and application. Background technique [0002] Far-infrared rays refer to invisible light with a wavelength of 5-14 microns, because it is close to the vibration frequency of cell molecules in the human body. After penetrating into the body, it will cause the resonance of atoms and molecules in human cells. Through resonant absorption, the friction between molecules generates heat to form a thermal reaction, which promotes the temperature rise in the deep subcutaneous layer, expands microvessels, accelerates blood circulation, helps to remove blood vessel accumulation and harmful substances in the body, removes obstacles that hinder metabolism, and regenerates tissues. Rejuvenate, promote the production of enzymes, achieve the purpose of activating tissue cells, preventing aging and strengthening th...
