Abstract
The invention discloses a preparation technology of an environmentally-friendly air purification material, and belongs to the technical field of environmentally-friendly materials. The preparation method comprises the following steps: performing carboxylation modification on absorbent cotton, homogenizing to prepare nanocellulose, preparing a pretreated porous carbonmicrosphere blank from chitosan and silicon dioxide, carbonizing the pretreated porous carbonmicrosphere blank, sequentially reacting the carbonized pretreated porous carbonmicrosphere blank with epoxy resin and ethanolamine under the action of isocyanate, covering the surface of the obtained reaection product with a microcapsule layer of chitosan and sodiumligninsulfonate under the action of sodium dodecyl benzenesulfonate to prepare an adsorption material, mixing the adsorption material with the nanocellulose and bamboo fibers to prepare a pretreated nanofiber membrane, and reacting the pretreated nanofiber membranewith halogenated hydrocarbon to prepare the environmentally-friendly air purification material. The environmentally-friendly air purification material prepared in the invention has an excellent purification performance and can be repeatedly used.
Description
technical field [0001] The invention relates to the technical field of environment-friendly materials, in particular to a preparation process of an environment-friendly air purification material. Background technique [0002] In recent years, the problem of indoor environmental pollution has become increasingly prominent. The existence of pollutants will endanger human health, reduce the quality of life, affect work efficiency, and reduce human immunity. Therefore, environmental purification materials have received more and more attention. [0003] Air purification materials absorb and decompose harmful substances in the air through physical and chemical methods. The application of air purification materials is an effective way to control air pollution sources. Patent CN201511029041.4 discloses algaecalcium mineral air purification medium and its preparation method, that is, the application is composed of algae mineral micropowder, calcium micropowder, catalytic micropowde...
