Abstract
The invention discloses a method for preparing a moisture-content-adjustable material, which comprises the following steps: A) preparing solution at certain concentration of sodium chloride and potassium carbonate, which are in a certain ratio; B) immersing aluminum oxide and potassium carbonate in solution prepared by the step A) for a certain period of time; C) adding ethyleneglycol diglycidyl ether, sodium carboxymethyl cellulose, sodium polyacrylate, and aluminum oxide and kieselguhr, which are obtained after salting in the step B, into a certain amount of deionized water, mixing and uniformly mixing; and D) drying the mixture obtained by the step (C), and thus, obtaining the moisture-content-adjustable material. Compared with the conventional moisture-content-adjustable material, the moisture-content-adjustable material prepared by the method has the advantages that: 1) the preparation method is simple and low in cost; 2) the moisture content response speed is high, and the moisture content is high; 3) moisture-content-adjustable materials with different target moisture content can be prepared by controlling the type of an inorganic salt; and 4) the toxicity, harm and pollution to the environment are avoided, and the method is in line with environment-friendly development trend.
Description
Technical field
The present invention relates to a kind of preparation method of humidity adjusting material, belong to a kind of environmentally conscious materials technical field.
Background technology
As an ancient civilized country with history in several thousand, China's historical relic is of a great variety, and quantity is abundant, and is of the remote past, therefore has very important historical, art and scientific value.But a lot of historical relics are subjected to the influence of microenvironment of living in to suffer destruction and damage in various degree after being unearthed, and wherein are no lack of much priceless, not reproducible rare cultural relics, just can't recover in case damage.
Essential environmental factors to the historical relic influence has temperature, humidity, illumination, atmospheric pollution, microorganism etc., and wherein humidity is a very important quality index in museum's environmental quality.No matter be metal (copper, iron, except the gold), still nonmetal (mural painting, ancient glass, the pottery that is unearthed, spin inorganic organic substances such as dyeing and weaving product, paper, woodenware) influenced by it all can, and humidity is controlled improper meeting and brought huge disaster to historical relic: the too high meeting of relative humidity causes the active and corrosion of metal of mould; Relative humidity is as the low embrittlement that then can cause moisture material, as contraction, the cracking of woodenware, the fracture of paper etc.; Dyestuff is rapider than fading when relative humidity is low when relative humidity is higher; Alternately changing then of relative humidity can accelerated material fatigue, makes its distortion aggravation, and vertical is that pottery, stone inscription also are difficult to escape by luck.Therefore the control of relative humidity has great importance for the preservation of historical relic.
Summary of the invention
The objective of the invention is to overcome the deficiency that prior art exists, and a kind of ambient humidity of regulating automatically is provided, preparation cost is low, the preparation method of the humidity adjusting material that the humidity response is fast.
The objective of the invention is to finish by following technical solution, the preparation method of described humidity adjusting material, this preparation method adopts following steps:
A) salt of wormwood and sodium-chlor are joined in certain deionized water, stirring and dissolving makes inorganic salt solution, and wherein the consumption of salt of wormwood is 1.5 ~ 2 times of the mass ratioes of sodium-chlor consumption, and the consumption of deionized water is 4 times of the mass ratioes of sodium-chlor consumption;
B) aluminum oxide and diatomite are impregnated into A) in the solution of preparation, vacuumize the 30min after-filtration, obtain adsorbing aluminum oxide and diatomite after saturated; Wherein the consumption of aluminum oxide is identical with amount of sodium chloride, and diatomaceous consumption is 2/3 times of the mass ratio of sodium-chlor consumption;
C) with ethylene glycol bisthioglycolate glycidyl ether (PGDE), Xylo-Mucine (CMC), sodium polyacrylate (PAAS) and step B) mixture that obtains after filtering, add a certain amount of deionized water and mix stirring, wherein the consumption of ethylene glycol bisthioglycolate glycidyl ether PGDE is the mass ratio 1/3 of sodium-chlor consumption, the consumption of Xylo-Mucine CMC is the mass ratio 2/3 of sodium-chlor consumption, the consumption of sodium polyacrylate is the mass ratio 1/3 of sodium-chlor consumption, and the consumption of deionized water is identical with the sodium-chlor consumption.
D) with C) in the mixture of preparation namely get humidity adjusting material after putting into the baking oven inner drying.
The selected aluminum oxide of the present invention is the porousness aluminum oxide.
The present invention puts into solution dipping for some time after-filtration of sodium-chlor and salt of wormwood preparation with porous alumina and diatomite, and mixes the dry preparation in back humidity adjusting material with ethylene glycol bisthioglycolate glycidyl ether (PGDE), Xylo-Mucine (CMC), sodium polyacrylate (PAAS), deionized water and stirring.Compare with existing humidity adjusting material, have following outstanding advantage: 1) preparation method is simple, and cost is low; 2) the humidity response speed is fast, the moisture content height; 3) can prepare the humidity adjusting material of different target humidity by the kind of control inorganic salt; 4) nontoxic, harmless, pollution-free to environment, meet the trend that environmental protection develops.
