Problems solved by technology

Invention patent CN200910101489.0 discloses a preparation method of a temperature-adjusting and humidity-adjusting material, which is used for humidity regulation of the microenvironment, but the polyethylene glycol and gelatin in it will block the pores of sepiolite itself, and water molecules will enter the interior of the resin It is not easy to desorb after desorption, so the moisture absorption and release performance of the material, especially the moisture release performance, is limited, and it is prone to hysteresis and hysteresis, and the wet capacity is not large enough.

Abstract

The invention relates to a method for preparing a high-efficiency composite humidity controlling agent. In the method, raw materials, such as acrylamide, sodium polyacrylate, carboxymethylcellulose, sepiolite and the like, are synthesized into a humidity controlling material, so that the advantages of various humidity controlling materials are combined and the wet unit weight and the humidity controlling property of the synthetic material per se are improved; and a great number of hole structures with aperture between 2 and 50 nanometers are formed on the material through the synthesis process, so that the absorption and desorption properties of the product are further improved. Compared with the prior art, the method has the advantages of: 1) large absorption and desorption capacities, high absorption and desorption response speed and capacity of efficiently and quickly adjusting the relative humidity of a microenvironment; 2) very convenient regeneration and reutilization; 3) simple production process and equipment and easy industrialization; and 4) no harmful substance generated in the production process.

Description

technical field [0001] The invention relates to a preparation method of a humidity-conditioning agent, in particular to a preparation method of a high-efficiency composite humidity-conditioning agent. Background technique [0002] 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 northern area during the dry period is as low as 10%. Humidity adjustment is very necessary. [0003] Humidity adjustment methods include mechanical adjustment and non-mechanical adjustment. The machinery for adjusting humidity mainly includes dehumidifiers, humidifiers, and constant humidity air conditioners. The advantage of this method is high efficiency, but the disadvantage is that it consumes ...
