Description
Technical field
The invention belongs to deoxidation drying agent technical field, relate to a kind of deoxidation drying agent and preparation method thereof.
Background technology
Drier is a kind of deicer absorbing moisture from air, is, by physics mode, Water Molecular Adsorption is absorbed hydrone change its chemical constitution in the structure of self or by chemical mode, becomes another material.It is applicable to prevent instrument, instrument, electric equipment, medicine, food, textile and other various connection with wrapping of piece from making moist.
What the use of current market was more is exactly silica-gel desiccant, as the patent No. a kind of silica-gel desiccant disclosed in the patent of invention of CN104174373A, silica gel is selected: 50-70% according to weight percent, alundum (Al2O3): 12-15%, di-iron trioxide: 8-10%, calcium chloride: 5-8%, magnesium sulfate: 3-6%, carboxymethyl cellulose: 8-15%, essence: 0.7-1.0%, the silica gel will chosen again, alundum (Al2O3), di-iron trioxide, calcium chloride, magnesium sulfate, carboxymethyl cellulose, after essence mixes, pellet is pressed into extruder, and send into dryer, dry in 120-130 DEG C of drying environment and get product.Advantage of the present invention is: adsorption rate is fast, adsorption capacity is large, can also provide the air of delicate fragrance, promote air quality further.Silica-gel desiccant normally uses sodium metasilicate and sulfuric acid reaction, and obtains through a series of processing procedures such as aging, sour bubbles, and raw materials for production are dangerous material, process more complicated.
Also have number acid, alkaline drier, general water absorbing capacity is larger, and rate of drying also than comparatively fast, but can not regenerate use mostly.
Molecular sieve desiccant is also a kind of, be Prof. Du Yucang and hydrone had to the desiccant product of stronger adsorptivity, belong to crystalline aluminosilicate compound, regular and uniform duct is had in its crystal structure, aperture is the order of magnitude of molecular size, but its preparation process more complicated, result of use is also restricted.
At present, using more is that bentonite drier adsorption rate is fast, high adsorption capacity, the water being equivalent to own vol 8-20 times can be adsorbed and be expanded to 30 times, more have stronger cation exchange capacity (CEC) and adsorption capacity, nontoxic, tasteless, contactless property burn into is pollution-free, especially to human body fanout free region.As the patent No. a kind of long-acting removal moisture drying agent disclosed in the Chinese patent of CN104258695, product absorption property under room temperature and general humidity is good, there is the effects such as adsorption activity, static dehumidification and peculiar smell removal, be widely used in, in the dry industry of each needs, there are the potentiality of very large competition in the international market.But these bentonite drier function singlenesses, only have desiccation, and it are low to recycle rate at present, after recycling, drying effect is poor, and adsorption effect need to improve.
Summary of the invention
The object of this invention is to provide a kind of deoxidation drying agent, have deoxidation and functions/drying concurrently, cation exchange capacity (CEC) is strong, and deoxidation obvious drying effect, recycles rate high; The present invention provides the preparation method of this deoxidation drying agent simultaneously, and technique is simple, low for equipment requirements, is applicable to large-scale industrial production.
The present invention in order to achieve the above object, adopts following technical scheme: a kind of deoxidation drying agent, comprises following component: iron powder, bamboo charcoal, sodium chloride, bentonite, quartz sand, water.
The component of the selected the best of this technical scheme, on the basis of functions/drying, increase deoxygenation function, be effective with minimum component, cost is low, and processing is simple.Iron powder has the effect of deoxidation, but simple iron powder be just easy in the external world oxidized fall, as the weak effect of deoxidier, process together with bamboo charcoal, sodium chloride, bentonite etc., can iron powder be played a protective role, maintain the effect of deoxidation.
Bamboo charcoal, sodium chloride, bentonite all have adsorption function, and three mixes, more remarkable than the adsorption effect being used alone thrin, and adsorption capacity can reach and be used alone bentonitic at least 3 times; Sodium chloride not only increases adsorption dry efficiency, and together with quartz sand, contributes to the dispersion of each component in mixture, especially after employing a period of time, avoids the agglomerating of drier, ensures the reusable deoxidation drying effect of deoxidation drying agent.
As preferably, the interpolation percentage of each component is: iron powder 10-35%, bamboo charcoal 1-8%, sodium chloride 1-8%, bentonite 1-5%, quartz sand 50-60%, water 10-25%.
As preferably, deoxidation drying agent also comprises hollow beads that weight ratio is 1-10% and weight ratio is the fiber of 5-10%.
In this technical scheme, fiber provides one to adhere to medium for mixture, after adsorbing the materials such as a large amount of water, can not change original steric configuration, thus can not affect the deoxidation functions/drying of itself at deoxidation drying agent; Hollow beads plays the effect of loosen collagen fibre, the effect of further reinforcing fibre.
As preferably, the diameter of described fiber is 5-15 μm, and the length of described fiber is 0.1-1mm.
As preferably, described fiber is the mixture of bamboo fibre and viscose rayon, and the mass mixing ratio of described bamboo fibre and described viscose rayon is 1-3:1.
Bamboo fibre and viscose rayon all have good hygroscopicity, and good with bentonitic tack, especially viscose rayon, and bentonite etc. adhere to evenly thereon, and adhesive force is good, thus deoxidation drying agent is reproducible.
By above-mentioned enforcement such scheme, deoxidation drying agent provided by the present invention has deoxidation and functions/drying concurrently, and cation exchange capacity (CEC) is strong, and deoxidation obvious drying effect, recycles rate high.
A preparation method for deoxidation drying agent, comprising: (1), by bamboo charcoal, sodium chloride, bentonite, quartz sand mixing, adds water, stirs; (2) in the mixture of step (1) gained, hollow minute particle is added, mixing; (3) by fiber and iron powder, after stirring, join in the mixture of step (2) gained, mixing, obtains deoxidation drying agent.
Further preferably, step (3) is carried out under vacuum.
As preferably, described bentonite obtains through following steps: after (I) dries bentonite material under 70-90 DEG C of condition, is crushed to 300-500 order, obtains raw meal; (II): raw meal is joined in sodium salt solution, process 2-5 hour, filters, obtains treatment fluid; The weight ratio of raw meal and sodium salt solution is 1:1-3; Zeolite is added in (III) treatment fluid, in mixing plant, stir process 1-3 hour, mixing speed is 200-300 rev/min; The treatment fluid that (IV) step (III) obtains obtains stand-by bentonite after concentrated, drying.
Occurring in nature, mainly based on calcium-base bentonite, after being dispersed in water, though individual particle has slight expansion, still keep coherent condition between crystal grain, adsorption effect is poor, utilize sodium salt to carry out pre-treatment to it, bentonitic crystal layer can be opened further, its adsorptivity can be significantly improved.Moreover, the heavy metal that zeolite can exist in adsorption treatment liquid, especially heavy metal lead, can also decolour to treatment fluid, with above-mentioned rotating speed stir process 1-3 hour, fully heavy metal contaminants is fallen in absorption, ensures the security of product, improves the whiteness of product, be particularly used in the deoxidation drying agent in food, this process is even more important.
As preferably, described sodium salt is the mixture of one or more in sodium carbonate or sodium acid carbonate or sodium pyrophosphate, and the concentration of sodium salt is 50-80%.
As preferably, described sodium salt is the mixture of sodium carbonate and sodium pyrophosphate, and mass mixing ratio is 3-5:1.
By above-mentioned enforcement such scheme, preparation method's technique provided by the present invention is simple, low for equipment requirements, is applicable to large-scale industrial production.
