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
The invention belongs to the preparing technical field of modified inorganic material, that relate to is a kind of preparation method with nanotubes structure humidity adjusting material of good moisture absorption and desorption property.
Background technology
Air humidity is the important environmental parameters that and people's life and production have substantial connection.Humidity is all significant to the protection of human comfort, IAQ, article.Temperature controlling is fairly simple effectively at present, but still relatively more difficult to the control of air humidity, especially concerning historical relic, medicine, high-grade jewelry etc., the infringement that the damage ratio temperature that the envionmental humidity fluctuation causes causes is big.Therefore humidity is control effectively and seem even more important and urgent.Humidity adjusting material is to need not non-renewable energy resources such as consumes electric power, have the good ecological environment material nd of regulating the air humidity ability automatically, to energy savings, improve amenity property, promote that the sustainable development etc. of ecological environment is significant.
The nanotube galapectite is a kind of aluminosilicate mineral, has the hollow nano tubular structure, and caliber is between 10～30nm, and between pipe range 10～30um, its chemical composition is identical with kaolinite, but contains higher moisture than kaolinite.Nanotube galapectite surface and interlayer contain active hydroxyl, add that its special nanotubes structure provides theoretical foundation to absorb-discharge humid.The inorganic mineral material hygroscopic capacity is limited, but its moisture releasing and power of regeneration are more intense.With the galapectite of 1-dimention nano pipeline configuration carry out certain thermal activation and acid activation modify handle after; Can change its specific area, pore size and distribution thereof finally influence its moisture absorption and desorption property; Increase wet volume capacity; Make the moisture absorption and the moisture releasing speed of response fast, and do not met report with the nanotube galapectite as humidity adjusting material, the method that therefore the present invention relates to has practicality and novelty.
Summary of the invention
The object of the present invention is to provide a kind of preparation method with special nano tubular structure, good moisture absorption and desorption property, the preparation method is simple, cost is low humidity adjusting material.
The technical scheme that the present invention adopts is such:
A) powdery nanotube galapectite (200-500 order) is added to the water with weight ratio 1: 10～100, centrifugation 10～30min filters the galapectite that suspends in the ore pulp, and drying makes the purified nanotubes galapectite;
B) the nanotube galapectite behind the purifying being joined mass percent concentration with weight ratio 1: 10～20 is in 3～10% the hydrochloric acid solution, under 20～30 ℃ of temperature, stirs 2～3 hours, and drying makes acidifying nanotube galapectite;
C) the nanotube galapectite of getting after the acidifying is put into Muffle furnace, under 300～600 ℃ of temperature, calcines 1～4 hour, makes nanotubes structure humidity adjusting material.
The nanotube galapectite humidity adjusting material of the present invention's preparation has the fast characteristics of humidity response speed, can be used as the humidity adjusting material on basis simultaneously, is used to prepare other organic or inorganic composite humidity adjusting material.
The specific embodiment
A) powdery nanotube galapectite is sieved for twice with 200 orders and 500 orders, get particle diameter, take by weighing 1kg at 200-500 purpose powdery nanotube galapectite; Join in the 50kg water, centrifugation 30min filters the galapectite that suspends in the ore pulp; Drying makes the purified nanotubes galapectite;
B) the nanotube galapectite 700g behind the purifying being joined the 10kg mass percent concentration is in 10% the hydrochloric acid solution, under 20～30 ℃ of temperature, stirs 2 hours, and drying makes acidifying nanotube galapectite;
C) the nanotube galapectite of getting after the acidifying is put into Muffle furnace, under 500～600 ℃ of temperature, calcines 1 hour, makes nanotubes structure humidity adjusting material.
