Description
The present invention relates to a process for producing a water-absorbing bead for supplying moisture to agricultural products during distribution and a water-absorbing bead prepared thereby, and more particularly, to a process for producing a water- It is possible to maintain the moisture for a long time and to prevent the generation of fungus and odor so that the freshness during circulation of agricultural products such as ginseng can be kept constant for a long time, And a water absorbing bead produced by the method.
Generally, most of the agricultural products that can be stored or circulated contain about 85 ~ 95% of water. Such agricultural products lose freshness when they lose moisture. In other words, if the relative humidity in the air is too low, moisture will evaporate from the agricultural products during distribution, and the weight of the agricultural products will be reduced. If the moisture is evaporated excessively,
Most of the agricultural products lose their merchantability when the water loss is over 5%, and the price of receiving the farms due to the weight decrease is also decreased. The factors such as the temperature and humidity of the storage environment It is important to maintain the freshness of the agricultural product by keeping it within the range.
Meanwhile, agricultural products such as ginseng, grapes, tomatoes, strawberries, and the like are used in various forms of packaging materials for distribution. Most of the packaging materials are made of a bag having an inner space for feeding crops, So that the crops are designed to prevent moisture loss inside the crop due to contact with air during distribution.
For example, in the case of the packaging material having such a bag shape, most of the structures in which crops are put into the inner space and the mouth is fused or tied and sealed, a simple film type packaging material such as a lap is put on the upper part of the container, In particular, in the case of crops such as ginseng, a certain quantity of moisture-absorbed moss is enclosed with the crops to increase the distribution period, and thus the crops (ginseng) The freshness of the product is maintained for a long time.
As described above, packaging materials for agricultural products such as ginseng, grapes, tomatoes, strawberries, etc. are formed in a closed space so as not to expose the crops to air during distribution. Such structures are not suitable for circulation of agricultural products, There is a problem that the freshness can not be maintained for a long time.
In order to solve such a problem, in the case of the packaging material such as the domestic patent application No. 10-2009-0000034 (publication No. 10-2010-0014087, published on Mar. 10, 2010) or the domestic public utility model publication No. 20-1999-0039818 A hole is formed so that the crop is protected by the packaging material and is in contact with the air outside the packaging material. However, if a hole is formed in the packaging material as described above, the effect of preventing the corruption or discoloration of agricultural products But the effect is not as great as expected.
In particular, vegetables with a high moisture content, a low content of fiber and a low leaf content, compared to other crops, have a problem in that the evaporation of water occurs rapidly even at a small temperature change, and the productability is greatly deteriorated due to shedding or wilting.

Referring to FIGS. 1 and 2, a method of manufacturing a
1. A process for producing a mixture (S100) by mixing an acrylic monomer, a hydrophilic additive and a crosslinking agent,
The step (S100) of mixing the acrylic monomer, the hydrophilic additive and the cross-linking agent is a step of mixing the acrylic monomer, the hydrophilic additive and the cross-linking agent at a constant weight ratio to prepare a mixture.
In the present invention, the acrylic monomer is a conventional monomer used in a water absorbent resin, and may be one or two selected from the group consisting of an anionic acrylic monomer and an acrylic monomer containing a salt thereof, a nonionic acrylic monomer and an amino group, Particularly preferred are acrylic acid, methacrylic acid, 2-methacryloylethanesulfonic acid, 2- (meth) acryloylpropanesulfonic acid, 2- (meth) acrylamide-2-methylpropanesulfonic acid, (Meth) acrylate, 2-hydroxyethyl (meth) acrylate, 2-hydroxypropyl (meth) acrylate, methoxypolyethylene glycol (meth) acrylate polyethylene glycol ) -Dimethylaminoethyl (meth) acrylate, (N, N) -dimethylaminopropyl (meth) acrylamide, and mixtures thereof. Preferably from it is most effective to include acrylic acid or acrylamide.
In the present invention, the acrylic monomer may be contained in an amount of 10 to 30 parts by weight in the mixture of an acrylic monomer, a hydrophilic additive and a crosslinking agent. When the content of the acrylic monomer is less than 10 parts by weight, formation of a polymer is difficult, If included, the monomers can become entangled with each other and cause problems in manufacture.
The hydrophilic additive may be at least one selected from the group consisting of glycerin, sorbitan monolaurate, sorbitan monopalmitate, sorbitan monostearate, and sorbitan monooleate.
In the present invention, the hydrophilic additive may contain 5 to 15 parts by weight of the mixture of the acrylic monomer, the hydrophilic additive and the cross-linking agent. When the hydrophilic additive is used in an amount of less than 5 parts by weight, The gel strength of the bead may be lowered.
The crosslinking agent may be at least one selected from the group consisting of ethylene glycol diacrylate, ethylene glycol dimethacrylate, polyethylene glycol diacrylate, polyethylene glycol dimethacrylate, glycidyl acrylate, ethylene glycol diglycidyl ether, polyethylene glycol diglycidyl ether , N, N-methylenebisacrylamide, N-methylolacrylamide, triallylamine, triallyl cyanate, triallyl isocyanate and pentaerythritol can be used.
In the present invention, the crosslinking agent may contain 2 to 5 parts by weight of the acrylic monomer, the hydrophilic additive and the crosslinking agent. When the crosslinking agent is used in an amount of less than 2 parts by weight, the beads may be excellent in water absorption, When it is contained in an amount exceeding 5 parts by weight, the gel strength is excellent but the water absorption ability may be significantly lowered.
2. Step (S200) of adding water and a dispersant to the mixture and stirring the mixture using a stirrer in a nitrogen atmosphere,
The step (S200) of adding the water and the dispersant to the mixture and stirring the mixture using a stirrer in a nitrogen atmosphere is a step of injecting a certain amount of water and a dispersant into the mixture of the acrylic monomer, the hydrophilic additive and the cross- .
The water is used to dissolve the water-soluble acrylic monomer, the hydrophilic additive and the cross-linking agent, and the water may be included in an amount of 10 to 20 parts by weight based on 100 parts by weight of the total of the acrylic monomer, the hydrophilic additive and the cross-linking agent.
If the amount of water is less than 10 parts by weight, the amount of water may be too small to sufficiently dissolve and disperse the acrylic monomer, the hydrophilic additive and the cross-linking agent. If the amount of the water exceeds 20 parts by weight, The water content is too much and can take a long time to dry.
The dispersant is used to maintain the particulate phase and to maintain the dispersed phase in a stable system. Examples of the dispersant include a surfactant selected from the group consisting of sorbitan fatty acid ester, polyoxyethylene fatty acid ester, sucrose fatty acid ester, ethylcellulose and cellulose acetate More than one can be used.
In the present invention, the dispersant may contain 1 to 3 parts by weight based on 100 parts by weight of the total of the acrylic monomer, the hydrophilic additive and the crosslinking agent. When the dispersant is contained in an amount of less than 1 part by weight, And when it is contained in an amount exceeding 3 parts by weight, the particle size of the beads becomes fine and the beads can be adhered to each other during drying.
3. Step (S300) of polymerizing the stirred mixture by polymerization initiator to form a polymer,
The step (S300) of polymerizing the stirred mixture with a polymerization initiator to form a polymer is a step of forming a polymer using a polymerization initiator.

In the present invention, the polymerization initiator may be included in an amount of 2 to 5 parts by weight based on 100 parts by weight of the acrylic monomer. When the polymerization initiator is contained in an amount of less than 2 parts by weight, the gel strength of the produced beads may be weakened, , There is a possibility that the absorbability of the bead to be produced is lowered.
4. Drying the polymer (S400)
The step of drying the polymer (S400) is a step of removing water contained in the preparation of the polymer. In the step of drying the polymer (S400), the drying temperature is maintained at a temperature of 180 to 200 ° C for 30 to 60 minutes Can proceed.
In the present invention, when drying of the polymer proceeds over the upper limit range, the drying time or the temperature is excessively high, so that the physical properties of the beads to be produced may be deteriorated, or a fine powder may be generated in the subsequent milling step. The polymer is not sufficiently dried, and the absorption rate of purified water and silver nanoparticles from which chlorine is removed from the beads to be produced may be lowered.
5. Step of pulverizing the dried polymer to form beads (S500)
The step of pulverizing the dried polymer into a bead shape (S500) is a step of pulverizing the polymer produced through the drying step to form beads having a uniform particle size.
In the present invention, the dried polymer may be pulverized into a powder having a particle size of 1000 to 2000 탆 according to the size of beads to be manufactured by a worker. As the pulverizer for pulverizing to a particle size as described above, a pin mill A hammer mill, a screw mill, a roll mill, a disc mill or a jog mill may be used as the pulverizer, And the detailed description thereof will be omitted for convenience and clarity of explanation.
6. Step (S600) of preparing a mixed solution by mixing purified water and silver nanoparticles from which chlorine has been removed,

In the present invention, purified water from which chlorine has been removed is used. As described above, the residual chlorine contained in the raw water is necessary for disinfection treatment of raw water. However, since it is harmful to the human body as a result, . That is, the residual chlorine dissolved in the raw water causes an odor unique to the raw water such as tap water to cause discomfort to the user, adversely affect agricultural products that are distributed over a long period of time, and may cause the generation of carcinogens such as trilhomethan In the present invention, purified water in which chlorine has been removed from raw water is used, and purified water from which chlorine has been removed can be produced using a known filter or an ionizer. For the convenience of explanation and clarity, It will be omitted.
The silver nanoparticles are adsorbed by oxygen atoms (atomic oxygen) when they come into contact with the surface. It is known that the oxygen atoms sterilize or antimicrobial by dissolving bacteria and viruses by oxidizing the cell membranes. In the present invention, the size of the silver nanoparticles is not limited, but a powder of 1 nm to 1000 nm may be used, and preferably, it may be 10 nm to 200 nm.
In the present invention, silver nanoparticles are used as an example. However, the present invention is not limited thereto, and may be used in the form of a silver nano-colloid aqueous solution. The colloidal nano-silver nanoparticles have silver atoms dispersed in an aqueous solution in a cluster state and have a diameter of about several nm to 120 nm. These silver colloidal solutions are known to have strong sterilizing power against a variety of harmful bacteria and fungi.
