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 the 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.The control of temperature is at present fairly simple effective, but still more difficult to the control of air humidity, and especially, concerning historical relic, medicine, high-grade jewelry etc., the infringement that the damage ratio temperature that envionmental humidity fluctuation causes causes is large.Therefore humidity is control effectively and seems even more important and urgent.Humidity adjusting material is without non-renewable energy resources such as power consumptions, has the good ecological environment material nd of adjusting air humidity ability automatically, to saving the energy, improve amenity, promote that the sustainable development etc. of ecological environment is significant.
Nanotube galapectite is a kind of aluminosilicate mineral, has 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.Inorganic mineral material hygroscopic capacity is limited, but its moisture releasing and power of regeneration are more intense.The galapectite of 1-dimention nano pipeline configuration is carried out after certain thermal activation and acid activation modification processing, can change its specific area, pore size and distribution thereof, final its moisture absorption and desorption property that affects, increase wet volume capacity, make moisture absorption and the moisture releasing speed of response fast, and using nanotube galapectite and do not met report as humidity adjusting material, the method 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, preparation method is simple, cost is low humidity adjusting material.
The technical solution used in the present invention is such:
A) by order number, be that 200-500 object powdery nanotube galapectite is added to the water with weight ratio 1: 10～100, centrifugation 10～30min, filters the galapectite suspending in ore pulp, dry, makes purified nanotubes galapectite;
B) the nanotube galapectite after purifying be take to weight ratio 1: 10～20 and join in the hydrochloric acid solution that mass percent concentration is 3～10%, at 20～30 ℃ of temperature, stir 2～3 hours, dry, make acidifying nanotube galapectite;
C) the nanotube galapectite of getting after acidifying is put into Muffle furnace, at 300～600 ℃ of temperature, calcines 1～4 hour, makes nanotubes structure humidity adjusting material.
Nanotube galapectite humidity adjusting material prepared by the present invention, has the feature of humidity fast response time, can be used as basic humidity adjusting material, for the preparation of other organic or inorganic composite humidity adjusting material simultaneously.
The specific embodiment
A) powdery nanotube galapectite is sieved for twice with 200 orders and 500 orders, get particle diameter at 200-500 object powdery nanotube galapectite, take 1kg, join in 50kg water, centrifugation 30min, filters the galapectite suspending in ore pulp, dry, make purified nanotubes galapectite;
B) the nanotube galapectite 700g after purifying being joined to 10kg mass percent concentration is, in 10% hydrochloric acid solution, at 20～30 ℃ of temperature, to stir 2 hours, dry, makes acidifying nanotube galapectite;
C) the nanotube galapectite of getting after acidifying is put into Muffle furnace, at 500～600 ℃ of temperature, calcines 1 hour, makes nanotubes structure humidity adjusting material.
