Preferred embodiments of the method for producing an environment-friendly, low-carbon decomposable antibacterial material according to the present invention will be described with reference to the drawings. It becomes even easier to understand the purpose, characteristics and merits of

The present invention mixes, agitates, ferments, after-ripens, and dries livestock excreta with sawdust, a microbial culture medium, and microorganisms for compost rot, and then finely crushes the prepared compost particles into a synthetic resin, an antibacterial agent, and a binder. , pellets formed by hot mixing and extruding with a dispersant and a slip agent.

Livestock manure is a major cause of air pollution, soil pollution and water pollution.Similarly, synthetic resin not only does not decompose even after tens or hundreds of years, but also when incinerated. It is the main cause of environmental pollution that is deadly to the human body as it pollutes the atmosphere severely by scattering carbon dioxide in the atmosphere.

In view of such circumstances, the present invention prepares pellets that are raw materials for a wide variety of molded products by mixing compost particles produced from livestock excrement with synthetic resin, and prepares pellets that can be used as raw materials for agricultural and livestock products, industrial products, and automobile parts. Alternatively, it can be used as a material for injection molding, extrusion molding, etc. for various industrial containers, that is, by using livestock manure to eliminate air pollution, soil pollution, and water pollution, and incinerating a mixture of livestock manure and synthetic resin. By using it as an environmentally friendly low-carbon decomposable antibacterial material that makes it possible to perform low-carbon decomposing, it is resistant to moisture and shock, and not only can it guarantee a long life, but also environmental pollution during incineration or decomposition. It is an invention that enables the minimization of

In particular, livestock manure is mixed, agitated, fermented, after-ripened and dried with sawdust, microbial media and compost-ripening microorganisms, and then ground to prepare compost particles, thereby allowing the sawdust to absorb moisture, Sawdust and livestock manure are agitated and fermented together with microbial culture medium and microorganisms for compost fermentation to actively decompose livestock manure. To enable easy bonding with a synthetic resin.

The finely ground compost particles are mixed with a synthetic resin and bonded with a binder, and the antibacterial agent eradicates bacteria and the dispersant minimizes the shrinkage rate when molding the product, In addition, by preparing pellets formed by cutting while heat mixing and extruding so that it is easy to demold when molding products with a slip agent, agricultural and livestock products, industrial products, automobile parts or various It can be used as a material for injection molding, extrusion molding, etc. for industrial containers and industrial parts, that is, as an environment-friendly, low-carbon decomposable antibacterial molding material. Instead, the environmental pollution caused by incineration or decomposition can be minimized.

At this time, the microbial medium is a mushroom medium, and the microorganisms for composting may be Bacillus and lactic acid bacteria. Fermentation and decomposition, Bacillus and lactic acid bacteria promote fermentation of livestock manure mixed in sawdust to facilitate further decomposition.

Preferably, acrylic powder is further added to the compost particles to make it easier to bond with the compost particles with properties similar to the components of synthetic resin. To overcome the phenomenon of being vulnerable to moisture when a coating layer is formed and stored for a long period of time.

Preferably, the compost particles comprise 66-75 wt% livestock manure, 10-17 wt% sawdust, 11-17 wt% microbial medium, and 0.1-0.7 wt% compost-ripening microorganisms.

If the amount of livestock manure is 66 wt% or less, the efficiency of preventing environmental pollution in forming pellets is low, and if it is 75 wt% or more, it is not preferable because it contains excessive moisture. % or less, it is difficult to reduce the water content of livestock manure, and if it is 17 wt% or more, the composition ratio of livestock manure is relatively low, so the efficiency in forming pellets is low, and the microbial culture medium is 11 wt% or less, the fermentation rate is low. If the ratio is low, 0.7 wt % or more, it is not preferable because the sawdust is spoiled too much.

Incidentally, livestock manure may contain 50 to 58 wt% of cow manure, 2 to 8 wt% of pig manure, and 6 to 15 wt% of chicken manure.

Cow dung is rich in fiber, so if it is less than 50 wt%, it is not preferable because the composition ratio of pig manure and chicken manure, which are relatively low in fiber, becomes high. It is not preferable because the composition ratio of pig manure and cow manure is low. Also, although it is less than pig feces, it has a high water content, so the minimum is 6 wt% and the maximum is 15 wt%.

On the other hand, pellets consist of compost particles 30-50 wt%, synthetic resin 30-50 wt%, antibacterial agent 5-10 wt%, binder 2-3 wt%, dispersant 10-20 wt%, slip agent 0.5-1 wt%, acrylic Contains 0.1-1 wt% powder and 0.5-1 wt% oil.

Compost particles prepared by mixing, stirring, fermenting, after-ripening, and drying livestock manure, which is the source of environmental pollution, with sawdust, microbial culture medium, and microorganisms for compost rot, and then finely crushed and prepared, and synthetic resin, which is the source of environmental pollution, At 30 to 50 wt%, which is the same ratio as the compost particles, the weak physical properties of the compost particles, that is, the weak physical properties of the compost particles are supplemented with a synthetic resin, while the synthetic resin (polyethylene (PE), polypropylene (PP) or polyethylene Compost particles compensate for the weak physical properties of terephthalate (PET), that is, the physical properties that do not rot even after tens to hundreds of years, so that environmental pollution such as air pollution, soil pollution, and water pollution can be minimized. .

As an antibacterial agent, pozzolans can be applied to sterilize various bacteria contained in compost particles. And since it has an alkaline component of 3 to 4 ppm germanium, it has excellent effects such as air purification, sterilization, heavy metal purification, odor removal, deodorization, and neutralization of toxicity. , cow manure, pig manure, and chicken manure to eliminate various bacteria and make them safer to use. Limited to:

As a binder, maleic anhydride can be applied for strong bonding between the compost particles and the synthetic resin. and enable the fusion of compost particles, and if it is 2 wt% or less, the bonding force between the compost particles and the synthetic resin cannot be maintained, and if it is about 3 wt%, the compost particles and the synthetic resin It is preferable because it can keep the binding strength to the maximum.

As a dispersant, pellets prepared by bonding between compost particles and synthetic resin are used to minimize errors due to shrinkage when curing after injection, extrusion or molding of various agricultural and livestock products and industrial parts. Dolomite powders can be applied to minimize shrinkage, i.e., to minimize shrinkage, such dolomite powders containing their inherent constituents calcium oxide (CaO) and magnesium oxide (MgO). ) to minimize the shrinkage rate when manufacturing industrial parts after being contained in compost particles and synthetic resin and prepared as pellets. A low modulus, up to 20 wt%, is preferred as this allows for optimum shrinkage.

As a slip agent, pellets prepared by bonding between compost particles and synthetic resin are used to improve surface slidability when hardening after injection, extrusion or molding of various agricultural and livestock products and industrial parts. An amide-based slip agent can be applied to improve slipperiness (slipperiness) and make demolding easier. However, a compound having a neutral structure in which the hydroxyl group is substituted with an amino structure can be used.

Examples of amide slip agents include erucamide, oleamide, behenamide, stearamide, stearyl stearamide, stearyl erucamide, oleyl palmitylamide ( oleylpalmityl amide), and these amide-based slip agents are contained in compost particles and synthetic resins, and after being prepared as pellets, are made easier to release from molds when manufacturing industrial parts. When the content is 0.5 wt % or less, it is difficult to release the mold.

Acrylic powder has properties similar to the components of synthetic resin and facilitates bonding with compost particles. If the amount is 0.1 wt% or less, it will affect the bonding force between the synthetic resin and compost particles. is not possible and the content is up to 1 wt %, the bonding strength between the compost particles and the synthetic resin can be optimized, which is preferable.

The oil makes it possible to overcome the phenomenon of being vulnerable to moisture when it is stored for a long time by forming a coating layer when it is finished into pellets, and liquid paraffin can be applied as the oil. If the liquid paraffin content is less than 0.5 wt %, the coating power cannot be exhibited.

FIG. 1 is a process diagram showing the production method of the present invention , and FIG. 2 shows the process of converting livestock manure into compost particles applied to the production method of the environmentally friendly low-carbon degradable antibacterial material according to the present invention. It is a flow chart showing.

As shown in FIG. 1, the method for producing an environment-friendly low-carbon decomposable antibacterial material according to the present invention involves mixing, stirring, fermenting, after-ripening, and drying livestock manure with sawdust, a microbial culture medium, and microorganisms for compost rot. After that, the compost particles are finely ground to prepare compost particles (S10), and the compost particles are thermally mixed with a synthetic resin, an antibacterial agent, a binder, a dispersant and a slip agent, extruded and cut to form pellets (S20). consists of

After mixing, agitating, fermenting, after-ripening and drying livestock manure with sawdust, microbial culture medium and microorganisms for compost rot, the step of finely grinding to prepare compost particles (S10) enables the sawdust to absorb moisture. , Sawdust and livestock manure are agitated and fermented with microbial media and microorganisms for compost fermentation to actively decompose livestock manure, while further fermentation and decomposition are performed by after-ripening and drying, and even moisture is removed. In addition, the compost particles finely crushed and prepared in this way are mixed with the synthetic resin and bound with a binder, and the bacteria are eradicated with an antibacterial agent. In order to minimize shrinkage when molding a product with a dispersant and to facilitate demolding when molding a product with a slip agent, pellets are formed by cutting while hot mixing and extruding. By the step (S20) of preparing an environment-friendly low-carbon degradable antibacterial material to enable subsequent injection, extrusion or molding of agricultural and livestock products, industrial products, automobile parts, various containers, etc. Through such a product, it is possible not only to ensure a long service life by being resistant to moisture and shock, but also to minimize environmental pollution caused by incineration or decomposition.

More specifically, the step S10 includes, as shown in FIG. 2, preparing a compost mixture by mixing livestock manure with sawdust, a microbial culture medium, and compost-fermenting microorganisms (S11), and injecting air into the compost mixture. A fermented compost is prepared by stirring while stirring (S12), the fermented compost is post-ripened to prepare a post-ripened compost (S13), and the post-ripened compost is dried to prepare a dried compost (S14). ) and a step of finely pulverizing the dried compost to prepare compost particles (S15).

After preparing a compost mixture by mixing livestock manure with sawdust, a microbial culture medium and microorganisms for compost rottenness, the compost mixture is agitated while injecting air into the compost mixture to prepare a fermented compost. Uniform fermentation of the mixture is enabled and such compost fermented product is re-ripened in storage, i.e. re-ripened to provide a fully fermented composted post-ripe product and then dried to compost dry. These compost granules are then finely ground to prepare compost particles, which are then facilitated to bond with the synthetic resin.

At this time, in step S11, the compost mixture has a water content of 50 to 70%, and in step S12, the fermented compost mixture is fermented for two months to have a water content of 40 to 40%. In step S13, the post-compost ripening product is obtained by post-ripening the fermented compost for two months to make the water content 35 to 40%, and in step S14, the dried compost product is the post-composting product. The dried compost is dried to a moisture content of 5-10%, and in step S15, the compost particles are crushed to a particle size of 70-90 mesh.

Specifically, livestock manure consists mostly of water. In the present invention, sawdust is added to adjust the water content to 50 to 70%. In some cases, sawdust is too much to be combined with the synthetic resin, and if the moisture content is more than 70%, fermentation and after-ripening are difficult, which is undesirable.

Then, the compost mixture is fully fermented for 2 months to reduce the moisture content to 40-45% to prepare a fermented compost, and the fermented compost is again fully after-ripened in the storage for 2 months to remove moisture. Prepare a compost-ripened product with a content of 35-40%, dry the compost-ripened product again to prepare a compost-dried product with a moisture content of 5-10%, and then divide it into 70-90 mesh. It is crushed finely to make it easier to bond with the synthetic resin.

On the other hand, in step S10, the microorganism medium may be a mushroom medium, and in step S10, the compost-fermenting microorganisms may be bacillus and lactic acid bacteria.

The mushroom medium ferments and decomposes the livestock manure mixed in the sawdust, and Bacillus and lactic acid bacteria also promote fermentation of the livestock manure mixed in the sawdust to facilitate further decomposition.

Further, in step S20, acrylic powder is further added to the compost particles to facilitate binding with the compost particles with a property similar to the component of synthetic resin. In addition, when the pellets are finished, a coating layer is formed to overcome the phenomenon that the pellets are vulnerable to moisture when stored for a long period of time.

On the other hand, in step S10, the compost particles may contain 66 to 75 wt% of livestock manure, 10 to 17 wt% of sawdust, 11 to 17 wt% of microbial culture medium, and 0.1 to 0.7 wt% of microorganisms for compost ripening. .

If the manure of livestock is less than 66 wt%, the efficiency in forming pellets is low, and if it is more than 75 wt%, it is not preferable because it contains excessive moisture. In this case, it is difficult to dilute the water content of livestock manure, and if it is 17 wt% or more, the composition ratio of livestock manure is relatively low, so the efficiency in forming pellets is low, and the microbial medium is 11 wt%. If it is 17 wt% or more, the fermentation rate is low, and if it is 17 wt% or more, it is not preferable because it causes the sawdust to rot excessively. If it is 0.7 wt % or more, it is not preferable because the sawdust is spoiled too much.

Incidentally, in step S10, the manure of livestock may contain 50 to 58 wt% of cow manure, 2 to 8 wt% of pig manure, and 6 to 15 wt% of chicken manure.

Cow dung is rich in fiber, so if it is less than 50 wt%, it is not preferable because the composition ratio of pig manure and chicken manure, which are relatively low in fiber, becomes high. It is not preferable because the composition ratio of pig manure and cow manure, which is the Also, although it is less than pig feces, it has a high water content, so the minimum is 6 wt% and the maximum is 15 wt%.

In step S20, the pellets are composed of 30-50 wt% compost particles, 30-50 wt% synthetic resin, 5-10 wt% antibacterial agent, 2-3 wt% binder, 10-20 wt% dispersant, and 0.5-1 wt% slip agent. %, acrylic powder 0.1-1 wt%, and oil content 0.5-1 wt% are cut while hot mixing and extruding.

Compost is prepared by mixing, agitating, fermenting, after-ripening, and drying livestock manure, which is a source of environmental pollution, with sawdust, a microbial culture medium, and microorganisms for compost rot, and then crushing it finely, and composting synthetic resin, which is a source of environmental pollution. The ratio of 30 to 50 wt%, which is the same as the ratio of particles, is used to compensate for the weak physical properties of compost particles, that is, the physical properties that are weak in strength, with synthetic resins (polyethylene (PE), polypropylene (PP), or polyethylene terephthalate). (PET)), which does not rot even after tens to hundreds of years, is supplemented with compost particles to minimize environmental pollution such as air pollution, soil pollution, and water pollution.

Preferably, in step S20, the thermal mixing is performed at a temperature of 70-80°C for 15-30 minutes to facilitate mixing of the compost particles and the synthetic resin, at which time is 70°C or less and 18 minutes or less. In this case, the synthetic resin is not mixed smoothly into the compost particles, and if the temperature is above 80°C and for more than 30 minutes, the synthetic resin will be melted before the synthetic resin is evenly mixed with the compost particles. It is not preferable because it causes a phenomenon.

Further, in step S20, the extrusion is performed at a temperature of 160 to 190.degree.

INDUSTRIAL APPLICABILITY The present invention can be used in industrial fields to prevent environmental pollution such as soil pollution, groundwater pollution, air pollution, etc., and to produce various agricultural and livestock products and industrial parts from synthetic resin.
