It becomes even easier to understand the purpose, features, merits, etc. of the invention.

The environment-friendly low-carbon degradable antibacterial material according to the present invention is a compost prepared by mixing, stirring, fermenting, post-ripening and drying livestock manure with large sawdust, a microbial medium and a compost ripening microorganism, and then crushing the compost into small pieces. It consists of pellets formed by cutting particles while heat-mixing and extruding them together with a synthetic resin, an antibacterial agent, a binder, a dispersant and a slip agent.

Livestock manure is a major contributor to air pollution, soil pollution and water pollution. Similarly, synthetic resins do not rot after decades or even hundreds of years, but are incinerated. It is the main cause of fatal environmental pollution to the human body while carbon dioxide is scattered and pollutes the atmosphere extremely.

In view of these circumstances, the present invention prepares pellets used as raw materials for a wide variety of molded products by mixing compost particles produced from livestock manure with synthetic resin, and prepares pellets for agricultural, marine and livestock products, industrial products, and automobile parts. Or, it is used as a material for injection molding and extrusion molding of various industrial containers, that is, it eliminates air pollution, soil pollution and water pollution by utilizing livestock manure, and incinerates it with a mixture of synthetic resin together with livestock manure. By utilizing it as an environment-friendly low-carbon degradable antibacterial material that can be performed with low carbon, it is resistant to moisture and impact, can guarantee the life, and even pollutes the environment during incineration or decomposition. Is also an invention that can be minimized.

In particular, by mixing, stirring, fermenting, post-ripening and drying livestock manure with large sawdust, microbial medium and compost ripening microorganisms, and then crushing to prepare compost particles, it is possible to absorb water by the large sawdust. While stirring and fermenting large sawdust and livestock manure with a microbial medium and compost ripening microorganisms to achieve positive decomposition of livestock manure, further fermentation and decomposition are carried out with post-ripening and drying, and even water is removed. It makes it possible to realize the ease of binding with synthetic resin.

The compost particles prepared by being finely crushed in this way are mixed with a synthetic resin and bound with a binder, and the shrinkage rate when molding a product with a dispersant is minimized while eradicating bacteria with an antibacterial agent. In addition, by preparing pellets formed by cutting while heat-mixing and extruding so that demolding can be easily performed when molding a product with a slip agent, agricultural, marine and livestock products, industrial products, automobile parts or various types can be prepared. It can be used as a material for injection molding and extrusion molding of industrial containers and parts, that is, an environmentally friendly low carbon degradable antibacterial molding material, and is resistant to moisture and impact, and can guarantee its life. Instead, it will be possible to minimize environmental pollution during incineration or decomposition.

At this time, the microbial medium may be a mushroom medium, and the compost ripening microorganisms may be Bacillus and lactic acid bacteria. Specifically, the mushroom medium can easily produce manure from livestock mixed in large sawdust. Fermented and decomposed, Bacillus and lactic acid bacteria promote the fermentation of livestock manure mixed in the large sawdust to make it more easily decomposed.

Preferably, when acrylic powder is further added to the compost particles to facilitate binding to the compost particles with properties similar to the components of the synthetic resin, and by extension, oil such as liquid paraffin is further added to the compost particles to finish the pellets. The coating layer makes it possible to overcome the phenomenon of being vulnerable to moisture when stored for a long period of time.

Preferably, the compost particles contain 66 to 75 wt% of livestock manure, 10 to 17 wt% of large sawdust, 11 to 17 wt% of microbial medium, and 0.1 to 0.7 wt% of microorganisms for compost ripening.

When the amount of excrement of livestock is 66 wt% or less, the efficiency of preventing environmental pollution is low in forming pellets, and when it is 75 wt% or more, it is not preferable because it contains excessive water, and sawdust is 10 wt. When it is less than%, it is difficult to reduce the water content of livestock manure, and when 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. If it is 11 wt% or less, the fermentation rate is low, and if it is 17 wt% or more, it is not preferable because it causes the sawdust to spoil too much. If the rate is low and is 0.7 wt% or more, it is not preferable because the sawdust will be putrefactive too much.

Incidentally, livestock manure may contain 50 to 58 wt% of cow dung, 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 50 wt% or less, it is not preferable because the composition ratio of pig dung and chicken dung, which are relatively low in fiber, is high. If it is 58 wt% or more, it is the main cause of environmental pollution. It is not preferable because the composition ratio of pork feces and cow dung is low, and pork feces are limited to a minimum of 2 wt% and a maximum of 8 wt% in consideration of the high water content, and eventually chicken feces. In addition, although it is less than pork feces, it has a high water content, so it is limited to a minimum of 6 wt% and a maximum of 15 wt%.

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

Compost particles prepared by mixing, stirring, fermenting, post-ripening and drying livestock manure, which is an environmental pollution source, together with large sawdust, a microbial medium, and compost ripening microorganisms, and synthetic resin, which is an environmental pollution source, are used. The ratio of compost particles is set to 30 to 50 wt%, which is the same as the ratio of compost particles, and the weak physical properties of compost particles, that is, the weak physical properties of strength are supplemented by synthetic resin, while synthetic resin (polyethylene (PE), polypropylene (PP) or polyethylene. The weak physical characteristics of terephthalate (PET), that is, the physical characteristics that do not rot even after decades to hundreds of years, are supplemented with compost particles so that environmental pollution such as air pollution, soil pollution, and water pollution can be minimized. ..

As an antibacterial agent, pozzolan can be applied to sterilize various bacteria contained in compost particles, and such pozzolan has a far infrared wavelength ratio of 93 to 94%. Since it has an alkaline component of 3 to 4 ppm of germanium, it has excellent effects such as air purification, bactericidal action, heavy metal purification, malodor removal, deodorization, and toxicity neutralization. , Various bacteria existing in cow manure, pig manure and chicken manure are eliminated so that they can be used more safely. When it is 5 wt% or less, the sterilization effect is low, and the maximum antibacterial value is 10 wt%. Limited to:

As a binder, maleic anhydride can be applied because of the strong bond between the compost particles and the synthetic resin, and such maleic anhydride is a synthetic resin during heat mixing and heat stirring. And the compost particles can be fused, and if it is 2 wt% or less, the binding 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 can be fused with each other. It is preferable because the binding force can be maintained to the maximum.

As a dispersant, pellets prepared by bonding compost particles and synthetic resin to each other are used to minimize shrinkage errors when various agricultural, marine and livestock products and industrial parts are injected, extruded or molded and then cured. Dolomite powder can be applied to make it, i.e., to minimize shrinkage, and such dolomite powder has its own constituents, calcium oxide (CaO) and magnesium oxide (MgO). ), Which is contained in compost particles and synthetic resin and prepared as pellets, and then acts to minimize the shrinkage rate when manufacturing industrial parts. If it is 10 wt% or less, it shrinks. When the rate is low and up to 20 wt%, the shrinkage rate can be optimized, which is preferable.

As a slip agent, the slidability of the surface when various agricultural, marine and livestock products and industrial parts are injected, extruded or molded and then cured by utilizing pellets prepared by bonding compost particles and synthetic resin to each other. An amide-based slip agent can be applied so as to improve (slipperiness) and facilitate demolding, and such an amide-based slip agent has a high melting point of an amide-based compound synthesized from a fatty acid. However, a compound having a neutral structure in which the hydroxyl group is replaced with an amino structure can be used.

Examples of amide-based slip agents include erucamide, oleamide, behenamide, stearamide, stearyl stearamidel, stearyl erucamide, and oleyl palmitylamide (stearyl erucamide). oleylpalmityl amide), and these amide-based slip agents are contained in compost particles and synthetic resins to be prepared as pellets, and then easily removed from the mold when manufacturing industrial parts. Therefore, when it is 0.5 wt% or less, it is difficult to demold, and when it is up to 1 wt%, it is preferable because it can be optimally demolded.

Acrylic powder has properties similar to the components of synthetic resin and facilitates binding to compost particles, and when it is 0.1 wt% or less, it affects the binding force between the synthetic resin and compost particles. If the amount is up to 1 wt%, the binding force between the compost particles and the synthetic resin can be optimized, which is preferable.

Oil content makes it possible to overcome the phenomenon of being vulnerable to moisture when it is stored for a long period of time by forming a coating layer when it is finished into pellets, and liquid paraffin can be applied as oil content. Liquid paraffin is preferable because it cannot exert its coating power when it is 0.5 wt% or less, and the coating power of pellets can be optimized when it is up to 1 wt%.

FIG. 1 is a process chart showing a method for producing an environment-friendly low carbon-degradable antibacterial material according to the present invention, and FIG. 2 is applied to a method for producing an environment-friendly low carbon-degradable antibacterial material according to the present invention. It is a flowchart which shows the process of making the excrement of livestock into compost particles.

In the method for producing an environment-friendly low carbon-degradable antibacterial material according to the present invention, as shown in FIG. 1, livestock manure is mixed, stirred, fermented, post-ripened and dried together with large sawdust, a microbial medium and a compost ripening microorganism. After that, the compost particles are prepared by crushing them into small pieces (S10), and the compost particles are hot-mixed with a synthetic resin, an antibacterial agent, a binder, a dispersant and a slip agent, and cut while being extruded to form pellets (S20). Consists of.

After mixing, stirring, fermenting, post-ripening and drying livestock manure with large sawdust, microbial medium and compost ripening microorganisms, finely crushing to prepare compost particles (S10) enables absorption of water by the large sawdust. , Large sawdust and livestock manure are stirred and fermented together with a microbial medium and compost ripening microorganisms to realize positive decomposition of livestock manure, while further fermentation and decomposition are carried out by post-ripening and drying, and even water is removed. The compost particles prepared by being finely crushed in this way are mixed with the synthetic resin and bound with a binder, and the bacteria are eradicated with an antibacterial agent. While minimizing the shrinkage rate when molding a product with a dispersant, and forming pellets formed by cutting while heat mixing and extruding so that demolding when molding a product with a slip agent can be easily performed. In step (S20), an environment-friendly low-carbon degradable antibacterial material is prepared to enable subsequent injection, extrusion or molding of agricultural, marine and livestock products, industrial products, automobile parts or various containers. Not only is it resistant to moisture and impact and can guarantee its life, but it also makes it possible to minimize environmental pollution during incineration or decomposition.

More specifically, in step S10, as shown in FIG. 2, livestock manure is mixed with large sawdust, a microbial medium and a compost ripening microorganism to prepare a compost mixture (S11), and air is injected into the compost mixture. While stirring to prepare the compost fermented product (S12), the compost fermented product is post-ripened to prepare the post-compost ripened product (S13), and the post-compost ripened product is dried to prepare the compost dried product (S14). ), Compost dried material is crushed into small pieces to prepare compost particles (S15).

After preparing a compost mixture by mixing livestock manure with large sawdust, a microbial medium and compost ripening microorganisms, the compost mixture is agitated while injecting air into the compost mixture to prepare a compost fermented product. Uniform fermentation of the mixture is possible and such compost fermented products are post-ripened again in storage, i.e., re-ripened to prepare fully fermented post-compost ripened products, then dried and compost-dried. These compost dried products are crushed into small pieces to prepare compost particles, which are then easily combined 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 compost fermented product has the compost mixture fermented for 2 months to have a water content of 40 to 70. In step S13, the post-compost ripening product is aged for 2 months to bring the water content to 35-40%, and in step S14, the dried compost product is ripened after composting. The ripe product is dried to have a water content of 5 to 10%, and in step S15, the compost particles crush the dried compost product to a particle size of 70 to 90 mesh.

Specifically, most of the manure of livestock is composed of water, but in the present invention, the water content is adjusted to 50 to 70% by adding sawdust, and at this time, the water content is 50% or less. In some cases, the amount of sawdust is too large to be combined with the synthetic resin, and when the water content is 70% or more, fermentation and post-ripening are difficult to be performed, which is not preferable.

Then, the compost mixture is sufficiently fermented for 2 months to reduce the water content to 40 to 45% to prepare the compost fermented product, and the compost fermented product is sufficiently post-ripened in the storage for 2 months again to obtain water. After preparing a post-compost ripened product having a water content of 35 to 40% and drying the post-compost ripening product again to prepare a dried compost product having a water content of 5 to 10%, the amount is reduced to 70 to 90 mesh. Crush it into small pieces to make it easier to bond with synthetic resin.

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

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

Further, in step S20, acrylic powder is further added to the compost particles to facilitate binding to the compost particles with properties similar to the components of the synthetic resin, and finally, in step S20, oil such as liquid paraffin is added to the compost particles. In addition, a coating layer is formed when finished into pellets to overcome the phenomenon of being vulnerable to moisture during long-term storage.

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

When the manure of livestock is 66 wt% or less, the efficiency in forming pellets is low, and when it is 75 wt% or more, it is not preferable because it contains an excessive amount of water, and the sawdust is 10 wt% or less. 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 less than or equal to, the fermentation rate is low, and if it is 17 wt% or more, it is not preferable because it causes the sawdust to spoil too much. If it is 0.7 wt% or more, it is not preferable because it causes the sawdust to rot too much.

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

Cow dung is rich in fiber, so if it is 50 wt% or less, it is not preferable because the composition ratio of pig dung and chicken dung, which are relatively low in fiber, is high. If it is 58 wt% or more, it is the main cause of environmental pollution. It is not preferable because the composition ratio of pork feces and cow dung is low, and pork feces are limited to a minimum of 2 wt% and a maximum of 8 wt% in consideration of the high water content, and eventually chicken feces. In addition, although it is less than pork feces, it has a high water content, so it is limited to a minimum of 6 wt% and a maximum of 15 wt%.

In step S20, the pellets are compost particles 30 to 50 wt%, synthetic resin 30 to 50 wt%, antibacterial agent 5 to 10 wt%, binder 2 to 3 wt%, dispersant 10 to 20 wt%, slip agent 0.5 to 1 wt. %, Acrylic powder 0.1 to 1 wt%, and oil content 0.5 to 1 wt% are heat-mixed and extruded while being cut to form.

Compost particles prepared by mixing, stirring, fermenting, post-ripening and drying livestock manure, which is an environmental pollution source, together with large sawdust, a microbial medium, and compost ripening microorganisms, and synthetic resin, which is an environmental pollution source, are composted. The ratio of compost particles is set to 30 to 50 wt%, which is the same as the ratio of particles, and the weak physical characteristics of compost particles, that is, the weak physical characteristics of strength are supplemented by synthetic resin, while synthetic resin (polyethylene (PE), polypropylene (PP) or polyethylene terephthalate). (PET)) weak physical properties, that is, physical properties that do not rot even after decades to hundreds of years, are supplemented with compost particles so that environmental pollution such as air pollution, soil pollution, and water pollution can be minimized.

Preferably, in step S20, the thermal mixing is carried out at a temperature of 70 to 80 ° C. for 15 to 30 minutes to facilitate mixing of the compost particles and the synthetic resin, at which time 70 ° C. or lower and 18 minutes or less. In this case, it is not preferable because the synthetic resin is not smoothly mixed in the compost particles, and when the temperature is 80 ° C. or higher and 30 minutes or longer, the synthetic resin is melted before the synthetic resin is uniformly mixed in 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 ° C. so that the synthetic resin containing compost particles can be quickly extruded while being easily melted from 160 ° C. to 190 ° C.

INDUSTRIAL APPLICABILITY The present invention can be used in the industrial field where various agricultural, marine and livestock products and industrial parts are manufactured from synthetic resin while preventing environmental pollution such as soil pollution, groundwater pollution and air pollution.
