Abstract

The invention relates to an air purifying material and a preparation method thereof. The air purifying material is formed by mixing 30 to 50 percent of polar tourmaline powder, 10 to 30 percent of carbon nanometer tubes, 25 to 35 percent of zeolite powder and 15 to 30 percent of metal nanometer powder encapsulated with titanium dioxide. By utilizing the zeolite and the metal nanometer powder encapsulated with titanium dioxide which have the photocatalitic action and can enhance the dispersing property of tourmaline negative ions in a local area and utilizing the carbon nanometer tubes which have large specific surface and strong absorbing capacity, thereby the generated air negative ions have high concentration. The air purifying material can effectively absorb harmful gases, air foreign flavor and smoke, fully plays the role of negative oxygen ions in the restrain and the elimination of bacterial viruses, and can be widely applied to purifying the indoor air and improving the air quality of rooms and automobiles.

Description

technical field [0001] The invention relates to an air purification material and a preparation method thereof. Background technique [0002] At present, air negative ion generators are commonly used to increase the concentration of negative ions in the room, which not only consumes electricity, but also easily produces harmful gases, such as nitrogen oxides and ozone. [0003] Polar tourmaline (tourmaline) is a silicate rock mineral, its chemical composition is silicate, boron, magnesium, aluminum, etc., and it has piezoelectricity and pyroelectricity. Those with good piezoelectricity can be used in the electronics industry, and can be used in ceramics, health care products, clothing, tobacco and other industries. Polar tourmaline superfine powder can continuously release negative ions and emit far-infrared rays (4-14 microns), and can generate 0.06 mA of biological current to purify the air. With the development and development of high technology, polar tourmaline can be ...
