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 modified scolecite adsorption material. The preparation method comprises following steps: stearic acid is adopted for activation of scolecite, blending reaction with triethanolamine is carried out so as to obtain an ester amination solution, and in the reaction process, sesbania gum containing wheat germ powder is introduced, so that the absorptionperformance of an obtained finished product is improved, water purifying effect is improved; and at last the ester amination solution and a dimethyl carbonate solution of alumina are subjected to blending reaction, so that the antibacterial effect of the finished product is improved further. The modified scolecite adsorption material is high in stability, and excellent in quality and environmentprotection performance.

Description

technical field [0001] The invention belongs to the field of adsorption materials, and in particular relates to a preparation method of a modified calcium zeolite adsorption material. 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 ...
