Embodiment Construction

[0016] The invention provides a mineral composite air treatment agent, which is composed of modified sodium-based bentonite and modified activated carbon, and the weight percentage of the modified sodium-based bentonite in the composite air treatment agent is 30%-60%, The balance is the modified activated carbon, and the modified sodium bentonite is composed of sodium bentonite, iron sulfate, aluminum sulfate and magnesium sulfate, wherein the content of each component in the modified sodium bentonite is :

[0017] Sodium bentonite: 65-75%

[0018] Iron sulfate: 10-15%

[0019] Aluminum sulfate: 10-15%

[0020] Magnesium sulfate: 5-10%.

[0021] The present invention also provides the preparation method of the above-mentioned mineral composite air treatment agent, including a step of weighing raw materials according to weight percentage, including a step of crushing the raw material of sodium bentonite, and melting and burning the raw material of sodium bentonite after crus...

Abstract

The invention discloses a mineral composite air finishing agent and belongs to the field of indoor environmental protection. The mineral composite air finishing agent consists of modified sodium bentonite and modified active carbon, wherein the modified sodium bentonite accounts for 30 to 60 percentage by weight of the composite air finishing agent, and the balance is the modified active carbon; and the modified sodium bentonite consists of sodium bentonite, ferric sulfate, aluminum sulfate and magnesium sulfate. The invention also discloses a preparation method of the mineral composite air finishing agent. Experiments show that a function of removing air pollutant is obvious, and the removal rate of formaldehyde, benzene, ammonia, TVOC (total volatile organic composite), heavy metal, respirable particulate matters and the like is greatly improved. The mineral composite air finishing agent and the preparation method thereof are mainly used for treating indoor air pollutants.

Description

technical field [0001] The invention belongs to the field of indoor environmental protection, and relates to a novel air treatment agent, in particular to a mineral composite air treatment agent and a preparation method thereof. Background technique [0002] Bentonite is a clay rock with montmorillonite as the main component - montmorillonite clay rock. The matrix mineral of bentonite is montmorillonite (Montmorillonite), also known as microcrystalline kaolinite or jiaolingite, which is a hydrous aluminosilicate mineral containing a small amount of alkali metal and alkaline earth metal. The general chemical formula is [0003] Na x (H 2 O) 4 {(Al 2-x Mg x )[Si 4 o 10 ](OH) 2} [0004] Bentonite is one of the main non-metallic minerals in my country, especially in the Yangtze River Delta, with reserves of more than 2.46 billion tons. It is widely used in the fields of chemical industry, casting, metallurgy and environmental protection. Bentonite has a large specifi...
