Abstract

The invention discloses an air filter element for a cellular network active carbon filter and a preparation method thereof. The air filter element for the cellular network active carbon filter comprises the following raw materials in parts by weight: modified active carbon, common active carbon, a manganese compound, activated aluminum oxide and titanium dioxide spray. Through adoption of the air filter element, the formaldehyde removing capability in a short time is enhanced, and the defect of poor adsorption capability of the common active carbon specific to polar organic compounds such as formaldehyde, hydrogen sulfide and ammonia gas are overcome. Meanwhile, the accumulated adsorption amount is increased greatly, and nonpolar harmful gas such as VOCs (Volatile Organic Compounds) and benzene can be effectively adsorbed. The activated aluminum oxide is added, so that the air filter element has very high suitability in environments in high-humidity southern region, southwest region and the like, and the problem of poor adsorption effect of the active carbon and the manganese compound in high-humidity regions is solved. Moreover, a framework for making the active carbon filter element is fully utilized as a carrier of nano-titanium dioxide, so that the removal rate of harmful gas such as formaldehyde, benzene, ammonia gas, TVOCs (Total Volatile Organic Compounds) and nitrogen oxide is further increased.
