Abstract

The invention discloses an environment-friendly air purifying material, and a preparation method thereof, and belongs to the technical field of environment protection material. The preparation methodcomprises following steps: degreasing cotton is subjected to carboxylation modification and homogenizing so as to obtain nanometer cellulose, chitosan and silica are prepared into a pre-treated porouscarbon microsphere blank material, the pre-treated porous carbon microsphere blank material is subjected to carbonization, and is reacted with epoxy resin and ethanolamine successively under the effect of isocyanate, and the surface is coated with a micro capsule layer composed of chitosan and sodium lignosulfonate under the effect of sodium dodecyl benzene sulfonate so as to obtain an adsorptionmaterial, the adsorption material is mixed with the nanometer cellulose and bamboo fiber to prepare pre-treated nanometer fiber film, and the pre-treated nanometer fiber film is reacted with a halogenated hydrocarbon so as to obtain the environment-friendly air purifying material. The environment-friendly air purifying material possesses excellent purifying performance, and can be recycled.

Description

technical field [0001] The invention relates to the technical field of environment-friendly materials, in particular to an environment-friendly air purification material and a preparation process thereof. 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.
