Abstract

The invention provides a modified composite activated carbon air filtering material with a high specific surface area and preparation thereof. The modified composite activated carbon air filtering material is prepared from the following components in parts by weight: 40-50 parts of activated carbon, 20-23 parts of nano titanium dioxide hydrosol, 2-7 parts of rare earth oxide, 2-3 parts of tung oil, 1-5 parts of water glass, 4-6 parts of carbonate solution and 2-5 parts of mixed powder through the steps such as modifying, mixing and activating; the prepared product has high adsorption efficiency, and the specific surface area can reach 1,940-2,256m<2> / g; compared with traditional untreated activated carbon, the specific surface area is increased by 2.2 times or more, the service life is prolonged, and the purifying efficiency is improved; moreover, the modified composite activated carbon air filtering material has the effects of faint scent and sterilization, effectively improves the air quality and realizes a strong purifying effect.

Description

technical field [0001] The invention relates to the technical field of air purification materials, in particular to a high specific surface area modified composite activated carbon air filter material and its preparation. Background technique [0002] At this stage, with the rapid development of modern industry, air pollution is becoming more and more serious. Many countries have formulated environmental pollution control laws and established various purification facilities accordingly. At present, most of the air filter materials on the market in my country are non-woven membrane filters, which only have the function of dust removal, but do not have the functions of adsorption and germicidal lamps; Combined air filter materials, but poor adsorption, low processing efficiency, and short service life, increasing economic costs. Contents of the invention [0003] In view of the above-mentioned problems, the present invention proposes a modified composite activated carbon air...
