Embodiment Construction
[0010] A) Sieve the halloysite powder nanotubes twice with 200 mesh and 500 mesh, take the halloysite powder nanotubes with a particle size of 200-500 mesh, weigh 1kg, add it to 50kg water, and centrifuge for 30min. The halloysite suspended in the pulp is filtered and dried to obtain a purified nanotube halloysite;
[0011] B) 700 g of the purified halloysite nanotubes was added to 10 kg of a hydrochloric acid solution with a concentration of 10% by mass, stirred for 2 hours at a temperature of 20 to 30° C., and dried to obtain acidified halloysite nanotubes;
[0012] C) The acidified nanotube halloysite is put into a muffle furnace, and calcined at a temperature of 500-600° C. for 1 hour to prepare a nanotube-structured humidity-controlling material.

Abstract
The invention discloses a method for preparing humidity-controlling material with a nanotube structure. The method comprises the steps as follows: (A), purified nanotube halloysite is prepared; (B), acidified nanotube halloysite is prepared; and (C), acidified nanotube halloysite is taken and put into a muffle furnace, and is calcined for 1 to 4 hours under the temperature ranging from 300 to 600 DEG C so as to prepare the humidity-controlling material with the nanotube structure. The nanotube halloysite humidity-controlling material has the characteristic of high humidity response speed, can be used as basic humidity-controlling material at the same time, and is used for preparing other organic or inorganic composite humidity-controlling material.
Description
technical field [0001] The invention belongs to the technical field of preparation of modified inorganic materials, and relates to a preparation method of a nano-pipe structure humidity-regulating material with good moisture absorption and desorption performance. Background technique [0002] Air humidity is an important environmental parameter closely related to people's life and production. Humidity is of great significance to human comfort, indoor air quality, and protection of objects. At present, the temperature control is relatively simple and effective, but the control of air humidity is still relatively difficult, especially for cultural relics, medicines, high-end jewelry, etc., the damage caused by the fluctuation of the relative humidity of the environment is greater than the damage caused by the temperature. Therefore, it is more important and urgent to effectively control the humidity. Humidity-regulating materials are eco-environmental materials that do not n...
