Description

A kind of desiccant and preparation method thereof
Technical field
The present invention relates to a kind of desiccant and preparation method thereof, and in particular to a kind of dry containing the fragrance for touching essential oil Agent and preparation method thereof.
Background technique
With the raising of industrial manufactureization level, all trades and professions will use desiccant, and economic development promotes people's clothing Increase and the dependence to tool, need drying in preservation and transport.
There are many method now in the art about production desiccant, can satisfy the needs of people substantially, but for one A little special articles, high to moisture pick-up properties requirement, the general hydroscopicity of common desiccant is only 40% or less；Chinese patent CN101249418 discloses a kind of desiccant of high hydroscopicity, maximum although it is under conditions of 40 DEG C of temperature, humidity 90% Hygroscopic capacity can achieve 200% of own wt or more, but such mineral agent does not have fragrance, some high-grade clothings, The storage use of leatherware, stamp, camera, piano, computer, audio-visual facility is difficult to meet individual requirements；And it is some with fragrance silicon Desiccant hydroscopicity based on glue is again inadequate, and cannot be used for a long time again, therefore desiccant of today is no longer satisfied need It wants.
Summary of the invention
In view of the deficiencies of the prior art, the present invention provides a kind of desiccant and preparation method thereof, touch perfume (or spice) by being added Essential oil, Peppermint essential oil and Lavender so that this desiccant can not only meet the requirement of moisture pick-up properties, and have pure and fresh Pleasant fragrance, while having the function of antibacterial.
The technical scheme adopted by the invention is as follows:
A kind of desiccant contains the following substances ingredient and weight percent:
The partial size of the active carbon is 200~400 mesh.
The desiccant, preferably comprises following material composition and weight percent: anhydrous magnesium chloride 40%, active carbon 5%, Chitosan 45% touches essential oil 5%, Peppermint essential oil 2%, Lavender 3%.
The desiccant, preferably comprises following material composition and weight percent: anhydrous magnesium chloride 30%, active carbon 9%, Chitosan 56% touches essential oil 3%, Peppermint essential oil 1%, Lavender 1%.
The desiccant, preferably comprises following material composition and weight percent: anhydrous magnesium chloride 35%, active carbon 7%, Chitosan 50% touches essential oil 4%, Peppermint essential oil 2%, Lavender 2%.
It is described touch essential oil the preparation method comprises the following steps: touched in perfume (or spice) to fresh, be added and steam according to solid-liquid ratio 1:10~20 Distilled water is impregnated 2~4 hours, and concussion is interrupted in soaking process, and steam distillation is carried out after immersion, terminates to steam after extracting 6 hours It evaporates, collects essential oil, be dried over anhydrous sodium sulfate, can be prepared by touching essential oil.
The Peppermint essential oil the preparation method comprises the following steps: peppermint is put into container, heated by lower section and generate steam, peppermint Essential oil follows steam to evaporate, and the vapor containing essential oil becomes liquid after catheter collection is cooling, according to water and essential oil Specific gravity, the difference of density and separate Peppermint essential oil.
The Lavender the preparation method comprises the following steps: lavender is mixed with distilled water according to the solid-liquid ratio of 1:10~20, boil Boiling, the essential oil containing lavender ingredient are diffused into vapor, form the azeotropic mixture of water and oil, and azeotropic mixture is cooling, after separation It can be prepared by Lavender.
The present invention also provides the preparation methods of the desiccant, and the preparation method comprises the following steps: by formula ratio Anhydrous magnesium chloride, active carbon, chitosan, touch essential oil, Peppermint essential oil and Lavender and be mixed evenly and can make Obtain desiccant.
The present invention by by anhydrous magnesium chloride, active carbon, chitosan, touch essential oil, Peppermint essential oil and Lavender Mixing, prepares the fragrance desiccant with high hydroscopicity and fresh scent.
Active carbon is porous adsorbing material, while the noxious materials such as the formaldehyde in air, dimethylbenzene can be absorbed, and is being played Play the role of air cleaning while its suction-operated, while the shatter value of desiccant can be increased.
Anhydrous magnesium chloride is used as easy moisture absorbing component in the present invention, and anhydrous magnesium chloride is easy to contain with water molecules formation The hydrate of the different crystallizations water has extremely strong activity of water absorption.
Chitosan is containing a large amount of polar group hydroxyl and amino, these groups can form hydrogen between hydrone Key, thus fixed hydrone.
It touches in perfume (or spice) containing the various actives volatile components such as limonene, australene, terpinolene, Bronyl acetate, band There are strong scent, and lasting fragrance, while there is extensive bacteriostasis, essential oil is touched in addition in desiccant, is keeping Article achievees the purpose that antibacterial stacte while dry.
Peppermint essential oil tool has the effect of refreshing, and the mind that makes one of news rouses oneself, and touches essential oil and Lavender It is added in desiccant together, the smell of stacte can be made more pure and fresh pleasant.
Lavender is to generally acknowledge most calm, is releived, the plant of syngignoscism, it can releive intense strain, the calm mind, Pneumostatic is calmed down, just has hospital the volatile oil extracted from lavender for improving the sleep of the elderly in foreign countries；In Xinjiang, Neurasthenia and insomnia are also treated with lavender herb preparation by many Uygur medicine hospitals；There are also apparent antibacterials to make for lavender With the linalool contained in lavender is the main component of lavender antibacterial, it can inhibit 17 kinds of bacteriums, and (including Grain-negative is thin Bacterium and gram-positive bacteria), the growths of 10 kinds of fungies.
Desiccant of the invention is using easy hygroscopic salt, active carbon, chitosan and derived essential oil composition, the mechanism of action are as follows: Active carbon absorbs moisture as adsorbent material, and easy hygroscopic salt anhydrous magnesium chloride absorbs moisture and forms crystalline hydrate, further inhales Wet effect will continue to absorb water from environment and form liquid mixture；At this point, polar group hydroxyl and amino in chitosan Firm hydrogen bond can be formed, so that anhydrous magnesium chloride and activity in conjunction with the hydrone to dissociate in active carbon and liquid mixture Charcoal restores rapidly water absorbing capacity, while the volatile derived essential oil contained in desiccant can be dealt into air, play stacte Purpose, after chitosan constantly absorbs water, intramolecular and intermolecular hydrogen bond are constantly formed, and then form stable gel, thus Moisture is fixed in drier system, avoids the infiltration of moisture, while the diffusion of essential oil can be slowed down, plays it for a long time Stacte purpose.
It is according to the present invention to be formulated the obtained desiccant for having both the moisture absorption, antibacterial and perfume container, in 30 DEG C of temperature, humidity Under conditions of 90%, the hydroscopicity after 15 days can reach 380% of own wt or more, significantly larger than existing each dry in the market The hydroscopicity of drying prescription.
The present invention compared with the existing technology, has following advantages:
1. containing plants essential oil in desiccant, while playing diluting effect, achieve the purpose that stacte；
2. containing active carbon ingredient in desiccant, when carrying out the drying such as furniture, clothing indoors, while playing to nocuousness The suction-operated of substance；
3. each ingredient in the present invention is simple and easy to get, and the pure plant formula containing there are many, Environmental Safety, while having antibacterial Effect.
