Air purifying material and its preparing method

Abstract

The present invention discloses a kind of air purifying material and its preparation process. The air purifying material is the mixture of active carbon or nanometer LDHS, nanometer titania, and nanometer cerium oxide or Ce-Zr solid solution; or the mixture of active carbon or nanometer LDHS, and nanometer cerium oxide or Ce-Zr solid solution; or the mixture of nanometer titania, and nanometer cerium oxide or Ce-Zr solid solution. The present invention has the advantages of being practical, safe and convenient, long acting period, wide application range, etc. and is suitable for air purification in various kinds of fields, including furniture, automobile, house, etc.

Description

technical field [0001] The present invention relates to a kind of indoor air purification material and its preparation method and application, especially to a kind of Background technique [0002] At present, the air purification products on the market all have various defects. There are mainly the following air purification products: [0003] 1. Most of the biochemical products use chlorine dioxide slow-release technology, because chlorine dioxide itself has strong irritation and toxicity, so it is not suitable for consumers who have already lived in it. [0004] 2. Formaldehyde and other spray products combine with formaldehyde and other harmful gases to form suspended matter during use. If this air suspended matter is inhaled by the human body, it will have great side effects. [0005] 3. Formaldehyde sealing agent and formaldehyde scavenger can play a short-term purification effect, but after a long time, it will volatilize itself and gradually lose its effect. [0006...

AI Technical Summary

Problems solved by technology

[0003] 1. Most of the biochemical products use chlorine dioxide slow-release technology, because chlorine dioxide itself has strong irritation and toxicity, so it is not suitable for consumers who have already settled in

[0004] 2. Formaldehyde and other spray products combine with formaldehyde and other harmful gases to form suspended matter during use. If this air suspended matter is inhaled by the human body, there will be great side effects

[0005] 3. Formaldehyde sealant and formaldehyde scavenger can play a short-term purification effect, but after a long time, it will volatilize itself and gradually lose its effect

[0006] 4. Ozone and negative oxygen ion technology focus on disinfection, and the effect of removing harmful gases is not obvious

If the concentration is too high or used for a long time, it will have certain side effects on the human body

[0007] 5. Although traditional activated carbon materials can adsorb harmful gases, they will be saturated after a certain period of use, and the effect is not ideal

[0008] 6. Air fresheners and air fresheners only use fragrance to cover the smell of harmful gases and give people a fresh feeling, but have little effect on removing harmful gases. If they are used too much, they will aggravate air pollution and cause human discomfort.

[0010] 8. Inorganic antibacterial agents or air purifiers made of silver, copper, zinc and other metal ions or their oxides are too expensive and difficult to promote in practice
