Abstract

The invention discloses a preparation method of a compound humidifying material, which comprises the following steps of: a, adding 5 parts by mass of sodium chloride and 10 parts by mass of potassium carbonate in 35 parts by mass of water, uniformly stirring to obtain a mixed solution, then adding 15 parts by mass of sodium polyacrylate resin in the mixed solution for later use; b, preparing 5 parts by mass of sepiolite roasted at a temperature of 250-300 DEG C for 2-2.5h, 6 parts by mass of polyvinyl alcohol and 2 parts by mass of urea into a solution, adding the solution into the mixture obtained in the step a, mixing and stirring; c, adding 3 parts by mass of sodium chloride and 66.7 parts by mass of potassium carbonate in 200 parts by mass of water, stirring to obtain a mixed solution; and d, adding the mixture obtained in the step b into the mixed solution obtained in the step c, mixing and uniformly stirring, then drying at 140-150 DEG C in an oven to prepare the humidifying material. The humidifying material has the advantages of low cost, high response speed, good effect and simpleness in process, is convenient to use and is harmless and non-toxic.

Description

technical field [0001] The invention relates to the preparation of an environmental material, in particular to a preparation method of a composite humidity-adjusting material, which is mainly applicable to the humidity adjustment of the environment. Background technique [0002] Humidity-regulating materials have become a necessity for people who are pursuing quality of life now. The humidity control materials are generally humidity control particles, humidity control paper, humidity control balls and block humidity control materials. Humidity-regulating materials are relatively dense, which affects the response speed and are generally placed in less conspicuous places. A plastic humidity-regulating material will attract everyone's attention. [0003] Studies have shown that the most suitable humidity for human life is between 40-60%. In this humidity range, bacteria and fungi reproduce relatively slowly. For our living items, it will be better protected under this humidit...
