Abstract

The invention relates to a preparation method of tough humidity-controlling material, which comprises the following steps: a. based on parts by weight, adding 0.1 part of sodium carboxymethyl cellulose into 5 parts of water to prepare into a gel state, and placing for standby application; b. based on parts by weight, adding 0.3 part of sodium chloride, 2.7 parts of potassium carbonate, 1.25 parts of sodium pyrrolidone carboxylate and 0.4 part of kieselguhr into 100 parts of water to prepare solution; then, adding 4-4.5 parts of paper for daily use and 0.25 part of sodium polyacrylate powder into the prepared solution, stirring and pulping; c. mixing the products respectively obtained in step a and step b, and then pulping for 4-5 times; after that, adding 0.5-1.5 parts of viscose into the mixture, and evenly stirring; and d. carrying out papermaking on the raw material obtained in step c, and drying at the temperature of 80-90 DEG C to obtain the tough humidity-controlling material. The preparation method of the tough humidity-controlling material is simple in preparation technology and low in cost; and the prepared humidity-controlling material is good in humidity-controlling effect, rapid in response, convenient to use, hard to break and rapid in moisture absorption and release rate, and can be recycled.

Description

technical field [0001] The invention relates to the preparation of an environmental material, in particular to a preparation method of a tough humidity-adjusting material, which is mainly applicable to the humidity adjustment of the environment. Background technique [0002] In the current environment that emphasizes sustainable development, energy is becoming more and more scarce. The adjustment range of active humidity control is small, and the energy consumption is large. With the improvement of people's requirements on the living environment, it has become a current trend to prepare a recyclable, green and environment-friendly humidity control material. [0003] The quantity of humidity-conditioning material determines the range of regulation, for a wide range of humidity regulation. Humidity-regulating materials are increasingly in demand as building materials. Studies have shown that the most suitable environment for people to live in is a humidity of 40%-60%, and a...
