Problems solved by technology

However, such filter materials need to be needle-punched, compounded and sterilized, which is not only complicated in process, but also high in production cost.
And its filtering function will quickly decrease and disappear with multiple cleanings, the reuse rate is low, and some will cause secondary pollution

Abstract

The invention discloses a preparation method of a nanometer adsorption material. The preparation method comprises the following steps of using tetraethoxysilane as a precursor, hydrolyzing in an aqueous solution containing wheat germ, blending stearic acid and a sol treated by triethanolamine, and esterifying; blending the esteramine-modified sol and dimethyl carbonate, and dispersing; adding polyacrylamide, and performing quaternary ammonium reaction, so as to obtain a finished product. The preparation method has the advantages that the silicon sol, the wheat germ powder, the polyacrylamide and the quaternary ammonium salt are effectively compounded; the stability is high; the good synergistic absorption property is realized, the environment-friendly property in use is high, and the comprehensive property is excellent.

Description

technical field [0001] The invention belongs to the field of nano-adsorption materials, and in particular relates to a preparation method of nano-adsorption materials. Background technique [0002] With the development of modern industry, air pollution is becoming more and more serious. Many countries have enacted environmental pollution laws and established various purification facilities accordingly, but air pollution still exists. Due to family living facilities, smoking and other reasons, some harmful substances are also produced to pollute the indoor air. This combination of indoor and outdoor pollution greatly affects people's health. Therefore, all countries in the world regard industrial purification and family indoor purification as important research topics for controlling environmental pollution. Most of the existing air filter materials are non-woven fabrics or Membrane filtration, its function is only to remove dust. At present, there are only a few air filter...
