Abstract

The invention discloses a rice husk containing bactericidal active carbon filter material, which is characterized by being composed of the following raw materials in parts by weight: 130 to 150 parts of coconut shell active carbon, 5 to 7 parts of sodium silicate, 2 to 3 parts of sodium dodecyl benzene sulfonate, 3 to 5 parts of acetic acid, 2 to 4 parts of calcium superphosphate, 3 to 5 parts of urea, 3 to 5 parts of copper sulfate, 10 to 13 parts of pottery clay, 3 to 4 parts of silver oxide, 30 to 35 parts of rice husk, 14 to 16 parts of silicon dioxide, 4 to 6 parts of adsorption auxiliary agent, and a proper amount of water. The filter material is prepared by the following steps: grinding rick husk, then processing the rick husk by a chemical agent, mixing rick husk with silicon dioxide and active carbon, and finally subjecting the mixture to an activation treatment so as to increase the porosity and specific surface area; so that the filter material can eliminate a plurality of harmful gases. The filter material has the advantages that the raw materials are cheap, the cost is low, no organic solvent is used, the pollution is little, and the space for stacking the rick husk is saved. The filter material can be co-used with a porous substrate or non-woven cloth to produce air purification facilities such as air conditioner filter screen, air purification filter screen, and the like.

Description
