Abstract

The invention relates to a method for preparing a humidifying-purifying dual-function environmental material. The method comprises the following steps: (A) taking a sericin solution and beta-cyclodextrin in parts by mass, adding the components into a glutamine transaminase solution, uniformly stirring, standing for 1-3 hours under the condition of 20-30 DEG C, performing freeze drying under the condition of 50 DEG C below zero, and uniformly grinding; (2) taking the product obtained in the step (A), acrylic acid, sodium methacrylate, sodium carboxymethylcellulose, potassium peroxodisulfate and water, stirring and reacting for 0.5 hour at the temperature of 40-50 DEG C; (3) adding a glutaraldehyde aqueous solution into the product in the step (B) in parts by weight, stirring and reacting for 1 hour at the temperature of 55-75 DEG C; and (D) taking the products, activated carbon, a hydrophobic crystalline state silica molecular sieve, grinding and stirring uniformly, and obtaining the humidifying-purifying dual-function environmental material. The method has the beneficial effects that (1) the novel material is high in humidity response speed, high in moisture capacity and good in moisture absorption and desorption performance; (2) the material has the humidifying-purifying dual functions.

Description

technical field [0001] The invention relates to a preparation method of a dual-function environmental material for humidity adjustment and purification, and belongs to the technical field of environmental materials. Background technique [0002] Humidity-regulating materials are functional materials that can control water vapor adsorption according to changes in environmental humidity. When the humidity is high, the material can absorb water vapor in the environment; when the humidity is low, it can emit the water vapor absorbed by itself. Relative air humidity is an important parameter to measure the indoor environment. Appropriate humidity plays a very important role in human health and industrial and agricultural production. The annual average relative humidity in the humid areas of southern my country is 70% to 80%, sometimes as high as 95% to 100%, while the relative humidity in the dry period in the northern area is as low as 10%, so humidity adjustment is very necess...
