Inorganic air purification material

Abstract

The invention relates to a multifunctional material which has the functions of broad-spectrum and long-acting antibiosis and air purification, and a preparation method thereof. The material and the preparation method are characterized in that the air purification material is powdery and the basic component of the material is activated carbon with strong absorption property; the material comprises four constituents, wherein the first constituent is the mixture comprising nanometer silver particles and the activated carbon (antibiosis), and the second constituent is a mixture (photo catalyst) of nanometer titanium white powders (titanium dioxide) and the activated carbon, the third constituent is a mixture (far-infrared) comprising nanometer ceramic powders and the activated carbon, and the fourth constituent is a mixture (catalyst) comprising high rare earth and the activated carbon; the constituents are fully mixed after being prepared and are finely crushed into nanometer particles to be used. The purification material has the advantages of little air resistance, high bacterial efficiency, good purification effects of removing dust, harmful gas and ultra-fine particles, arbitrary shaping, longer service life, etc., and solves the problem of secondary environmental pollution caused by the former treatment using the chemical method and electric devices.

Description

technical field [0001] The invention relates to an air-purifying material, more precisely a broad-spectrum, long-acting multi-functional antibacterial and air-purifying inorganic material, which belongs to the field of material science. Background technique [0002] At this stage, with the rapid development of modern industry, air pollution is becoming more and more serious. Many countries have formulated environmental pollution control laws and established various purification facilities accordingly. However, air pollution still exists. It can be said that there is no pollution in automobiles, ships, living rooms, and industrial areas. This kind of indoor and outdoor pollution seriously affects people's physical and mental health. External purification is taken as an important research topic to control environmental pollution.

AI Technical Summary

Problems solved by technology

[0003] At present, most of the air filter materials on the market in our country are non-woven fabrics or membrane filters, whose functions are only dust removal, but not adsorption, sterilization, etc. The combined air filter material has the functions of sterilization, adsorption and filtration at the same time, but because the product needs to be acupuncture compounded and sterilized, the process is not only complicated, but also the production cost is high. More importantly, its related functions are related to Function will decrease and disappear quickly with time and cleaning

Through our data retrieval, there has not been an inorganic material that has a broad-spectrum, long-lasting bactericidal and antibacterial function, and can also quickly and effectively purify the air.
