Abstract

The invention discloses a low-cost long-lasting active carbon filter material capable of being stored easily. The filter material is characterized by being composed of the following raw materials in parts by weight: 130 to 146 parts of shell active carbon, 7 to 10 parts of aluminum oxide, 5 to 8 parts of iron oxide, 7 to 9 parts of magnesium oxide, 12 to 14 parts of attapulgite clay, 5 to 7 parts of zinc chloride, 2 to 3 parts of malic acid, 0.5 to 1 part of sorbic acid, 1 to 2 parts of succinic acid, 4 to 6 parts of polyacrylamide, 4 to 6 parts of adsorption auxiliary agent, and a proper amount of water. The active carbon is modified by adding activating components such as magnesium oxide, zinc chloride, and the like, and the modified active carbon has a large specific surface area and thus can effectively eliminate the acidic/alkaline/combined type volatile harmful gas. Moreover, an adsorption auxiliary agent, which has a plurality of tunnel structures and large specific surface area, is added to further improve the adsorption efficiency. Substances having the functions of eliminating odor and preventing corrosion such as sorbic acid, malic acid, and the like are added, thus the prepared filter material can be stored easily, the effect can last for a long time, and the filter material can be made into air conditioner filter screen.
