Description
Technical field
The invention discloses a kind of preparation method of composite humidity adjusting material, belong to building material technical field.
Background technology
" humidity adjusting material " refers to not by any artificial energy source and plant equipment, the change of ambient air humidity where perceiving
Change, the material of air humidity is automatically adjusted by the moisture absorption and desorption property of itself.When ambient humidity is higher, humidity adjusting material can adsorb
Vapor in air, reduce ambient humidity；When ambient humidity is relatively low, material can be desorbed the moisture of its absorption, improve environment
Humidity, so as to keep the relatively stable of ambient humidity.Any energy is not consumed during the materials'use, environment can be automatically adjusted
Humidity, to improving ambient humidity, save the energy, promote Sustainable Development of Ecological Environment to have great importance.Humidity adjusting material by
There is diversity, and the controllability of humid control in its product form, its application is not limited solely to the art work, historical relic
Deng the occasion with different humidity requirement, the antistaling agent of food, agricultural are alternatively arranged as, in building field etc..In addition, damping
Material also has broad application prospects in fields such as leather industry, daily-use chemical industries.
Integrate, the humidity adjusting material of Recent study exploitation can substantially be summarized as following 5 class：（1）Special silica-gel, silica gel
It is a kind of unbodied silica, there is loose structure, surface has substantial amounts of Si-OH, and hydrophily is preferable, has to hydrone
There is preferable absorption property.Silica gel absorption hydrone is mainly shown as physisorption.Silica gel is as a kind of most common tune
Wet stock, has been obtained for wide application, but its hygroscopic capacity is small and the problems such as hysteresis quality is serious, still greatly limitation
It is applied；（2）Inorganic salts, many inorganic salts can serve as humidity adjusting material, such as calcium chloride, zinc chloride, lithium chloride, potassium carbonate
Deng, but saltoutd because most of solid inorganic salt easily produces, and it is unstable, in addition will in view of Special uses such as transportation and packing
Ask, the saturated salt solution of liquid condition is also unable to reach, and is extremely limited its use；（3）Inorganic mineral material, such as
Montmorillonite, diatomite, sepiolite etc., the material have the advantages that distribution is wide, cost is low, processing is simple, and right wet volume capacity is low, duct
The problems such as uncontrollability of structure and size, seriously limits its application；（4）High-molecular organic material, exist mostly substantial amounts of
The hydrophilic groups such as carboxyl, amino, hydroxyl, and there is tridimensional network, there are very strong water absorbing properties.Compared to inorganic material,
For high-molecular organic material as conditioning agent, maximum advantage is exactly that hygroscopic capacity is big, but there is also one to limit its application for the material
The shortcomings that, it is exactly that hydrone is difficult to resolve analysis, thus it is barely satisfactory compared to excellent moisture pick-up properties, moisture releasing performance；（5）Composite wood
Material, as described above, four kinds of humidity adjusting materials can not all meet the requirement of high moisture adsorption and releasing speed and high moisture adsorption and releasing amount simultaneously above.Cause
This, it would be highly desirable to developing a kind of high humidity adjusting material of absorbent capacity has necessary meaning.
