Description
Technical field
The present invention relates to a kind of preparation method of humextant, particularly a kind of preparation method of high-efficiency composite humidity controlling agent.
Background technology
Relative air humidity is an important parameter weighing indoor environment, and suitable humidity all has a very important role to HUMAN HEALTH, industrial and agricultural production.China's south humid area annual relative humidity is 70%～80%, sometimes up to 95%～100%, reaches below 10% and the relative humidity of northern area drying period is minimum, and moisture control is very necessary.
The regulative mode of humidity has mechanical conditioning and on-mechanical to regulate.The machinery of regulating humidity mainly contains dehumidifier, humidifier and constant humidity air-conditioning etc., and the advantage of this mode is that efficient is high, and shortcoming is that adjusting humidity energy consumption is big but start shooting 24 hours every days continuously; On-mechanical is regulated and is mainly referred to utilize the moisture absorption and desorption property of humidity adjusting material to regulate ambient moisture independently, adaptively, and this mode need not any mechanical means and energy consumption, is a kind of environmentally friendly regulating and controlling method.
Humidity adjusting material is broadly divided into following several types: special silica-gel, polynite, inorganic salts, organic polymer material etc. respectively have relative merits.Composite humidity adjusting material is with making after dissimilar humidity adjusting materials and other subsidiary material hybrid reaction, and modal is the compound humidity adjusting material that is prepared from of super absorbent resin and mineral filler.Be used for the compound macromolecular material and have higher moisture absorption capacity usually, but because its molecule regular, the moisture that is adsorbed is difficult to resolve; The moisture releasing poor performance, compound (being generally ionogen or porous support) through macromolecular material and mineral filler can not only make full use of the superior water-absorbent of high molecular polymer; With mineral filler compound after; The inner ionic concn of polymkeric substance is improved, and then increase the osmotic pressure of polymkeric substance surfaces externally and internally, quicken polymkeric substance outside surface moisture and get into inner; Composite humidity adjusting material not only rate of moisture absorption increases, and moisture releasing speed also is greatly improved.Patent of invention CN200910101489.0 has announced a kind of preparation method of temperature-adjusting humidity-adjusting material; The moisture control that is used for microenvironment; But polyoxyethylene glycol wherein and gelatin can make the hole plug of sepiolite self; And water molecules is not easy desorption after getting into resin inside, so the moisture absorption and desorption property of material, particularly moisture releasing performance are restricted, it is also big inadequately to occur phenomenon, wet volume capacity that moisture releasing lags behind easily.The present invention utilizes matrix material to improve the wet volume capacity and the damping performance of synthetic materials itself; On material, form the pore structure of a large amount of nano-scales through building-up process, further improve the wet volume capacity and the moisture absorption and desorption property of product, more above-mentioned patent has higher damping speed and bigger moisture content.
Summary of the invention
The preparation method who the purpose of this invention is to provide a kind of high-efficiency composite humidity controlling agent; Technical scheme of the present invention is through synthetic with organic polymer material, natural macromolecular material, inorganic porous material; Be combined into humidity adjusting material, with the advantage that absorbs all kinds of humidity adjusting materials, wet volume capacity and the damping performance that improves synthetic materials itself; And pass through building-up process forms a large amount of nano-scales on material pore structure, with the moisture absorption and desorption property of further raising product.The fields such as keeping that are used for cultural relics in the collection of cultural institution protection, food, medicine, book and file have advantages such as the moisture adsorption and releasing response speed is fast, wet volume capacity is big, and renewable, recycling is convenient.
A kind of preparation method of high-efficiency composite humidity controlling agent is characterized in that adopting following steps:
A) getting 10 parts of granularities by mass fraction is 100 purpose sepiolites, and 3 parts of hydrochloric acid join in 100 parts of water, stirs 3 hours down at 50 ℃, filters, and with water washing three times, dries, and obtains the sepiolite after the activation;
B) get 5～15 parts of acrylic amides by mass fraction, 2 parts of ZX-Is, 2 parts of CMC 99.5s; Sepiolite after 4 parts of activation, 0.1 part of Potassium Persulphate, 0.03 part of N; N '-methylene-bisacrylamide, 0.4 part of aluminum chloride joins respectively in the reactor drum that 50 parts of water are housed; In temperature is under 60～80 ℃, stirring reaction half a hour;
C) mass fraction B set by step) is got 1.2 parts of sodium hydrogencarbonates and is joined in the above-mentioned reactor drum, and stirring reaction 3～5 hours obtains synthetic product;
D),, obtain required high-efficiency composite humidity controlling agent 150 ℃ of following heat treated 1～2 hour with after the synthetic product oven dry.
Product application of the present invention is protected in cultural relics in the collection of cultural institution, the calligraphy and painting collection, and food, food raw material, precision instrument, daily-use chemical industry, medicine, healthcare products, Chinese medicine is preserved, book and file keeping, fields such as textiles keeping.Technical scheme of the present invention is with organic polymer materials such as acrylic amide, ZX-I, CMC 99.5, sepiolites; Natural macromolecular material; Inorganic porous material is combined into humidity adjusting material through synthetic, with wet volume capacity and the damping performance of carrying synthetic materials itself; On material, form the pore structure that a large amount of apertures are 2～50nm through building-up process, further improve the moisture absorption and desorption property of product.These technology make wet volume capacity of the present invention, moisture adsorption and releasing response speed etc. than patent of invention CN200910101489.0 significantly raising arranged.Implement the super humextant (the humidity regulation target is RH50%) of sample (the humidity regulation target is RH55% ± 5%) and import, every 1m
3Enclosed space use the 1kg humextant, under the high humidity environment of RH90%, do wettability test respectively, in the low wet environment of RH30%, do the wet putting test, test material damping speed, comparing result is seen table 1; Under 105 ℃ drying of materials is arrived constant weight, the saturated wet volume capacity of test material under the condition of RH90%, comparing result is seen table 2.
