Detailed Description
The invention and its preferred embodiments of the environmentally friendly low carbon degradable antibacterial material and its manufacturing method are described with reference to the accompanying drawings, and there may be a plurality of embodiments, through which the objects, features and advantages of the invention can be better understood.
The environment-friendly low-carbon degradable antibacterial material provided by the invention is composed of the following trays: mixing livestock manure, sawdust, a microbial culture medium and microorganisms for composting, stirring, fermenting, after-ripening, drying, pulverizing to form compost particles, and hot mixing, extruding and cutting with synthetic resin, an antibacterial agent, a binding agent, a dispersing agent and an additive to form a tray.
The feces of livestock are the main causes of air pollution, soil pollution and water pollution, and in the same way, synthetic resin is not rotten for tens or hundreds of years, and carbon dioxide is released during incineration, so that serious air pollution is caused, and the fatal environmental pollution to human bodies is caused.
In view of this, the present invention prepares a tray, which is a raw material of various molded products, by mixing compost particles manufactured with livestock manure with synthetic resin, as a material for injection molding, extrusion or molding of agricultural and livestock products or industrial products, automobile parts or various industrial containers, etc., that is, by solving air pollution, soil pollution and water pollution with livestock manure, and by combining livestock manure with synthetic resin, as an environmentally friendly low-carbon degradable antibacterial material enables low carbon during burning, not only water and impact resistance, can secure a service life, but also can minimize environmental pollution upon incineration or even degradation.
In particular, the livestock manure is mixed with sawdust, a microbial culture medium and a microorganism for composting, stirred, fermented, post-cooked and dried and then crushed to form compost particles, so that the sawdust and the livestock manure can be absorbed by moisture, the sawdust and the microorganism culture medium and the microorganism for composting are stirred and fermented together to realize active degradation of the livestock manure, and the post-cooked and dried further ferment and degrade the livestock manure, and simultaneously remove the moisture, thereby being easily combined with the synthetic resin.
The compost particles formed by crushing are mixed together with synthetic resin and combined with a binder, while bacteria are eradicated with an antibacterial agent, shrinkage rate at the time of product molding is minimized with a dispersing agent, and demolding at the time of product molding is easily performed with a slip aid, and a tray is formed by cutting at the time of hot mixing and extrusion, and is used as a material for injection molding, extrusion or molding of agricultural and livestock products or industrial products, automobile parts or various industrial containers, etc., that is, it can be applied as an environment-friendly low-carbon degradable antibacterial material, not only is water and impact resistant, can ensure a service life, but also can minimize environmental pollution at the time of incineration or even degradation.
The microorganism culture medium can be mushroom culture medium, and the microorganism for composting can be bacillus and lactobacillus, specifically, the mushroom culture medium can enable livestock manure mixed into sawdust to be easy to ferment and degrade, and the bacillus and lactobacillus can promote the fermentation of the livestock manure mixed into sawdust, so that the livestock manure can be degraded more easily.
Preferably, acrylic powder is added to the compost particles, and the acrylic powder is easily bonded to the compost particles by utilizing properties similar to those of the synthetic resin component, and further, oil such as liquid paraffin is added to the compost particles, so that a coating layer can be formed when the tray is prepared, and the phenomenon of being easily damaged by water during long-term storage can be overcome.
Preferably, the compost particles comprise 66wt% to 75wt% of livestock manure, 10wt% to 17wt% of sawdust, 11wt% to 17wt% of microorganism culture medium, and 0.1wt% to 0.7wt% of microorganism for composting.
If the livestock manure is less than 66wt%, efficiency with respect to preventing environmental pollution is lowered when the tray is formed, and if it is more than 75wt%, excessive moisture is contained to be undesirable; if the sawdust is less than 10wt%, it is difficult to reduce the moisture content of the livestock manure, and if it is more than 17wt%, the composition ratio of the livestock manure is relatively lowered, and the efficiency of forming the tray is lowered; if the microbial medium is less than 11wt%, the fermentation rate will be reduced, and if it is more than 17wt%, the sawdust will be excessively decomposed, which is not preferable; if the amount of the microorganism for composting is less than 0.1wt%, the fermentation rate and the rate of composting are lowered, and if it is more than 0.7wt%, the sawdust is excessively decomposed, which is not preferable.
And the livestock manure can comprise 50 to 58 weight percent of cow manure, 2 to 8 weight percent of pig manure and 6 to 15 weight percent of chicken manure.
Cow dung is abundant in fiber, if less than 50wt% of the composition ratio of the pig dung and the chicken dung with relatively less fiber is increased to be undesirable, and if more than 58wt% of the composition ratio of the pig dung and the cow dung, which are main causes of environmental pollution, is reduced to be undesirable; considering the high moisture content of pig manure, the limit is at least 2wt% and at most 8wt%; furthermore, due to the high moisture content of chicken manure (although less than pig manure), it is limited to a minimum of 6wt% and a maximum of 15wt%.
In addition, the tray comprises 30 to 50 weight percent of compost particles, 30 to 50 weight percent of synthetic resin, 5 to 10 weight percent of antibacterial agent, 2 to 3 weight percent of bonding agent, 10 to 20 weight percent of dispersing agent, 0.5 to 1 weight percent of slip aid, 0.1 to 1 weight percent of acrylic powder and 0.5 to 1 weight percent of oil.
The compost particles formed by mixing, stirring, fermenting, post-ripening and drying livestock manure as an environmental pollution source with sawdust, a microorganism culture medium and composting microorganism together form a proportion of 30-50 wt% with synthetic resin as an environmental pollution source, so that the fragile physical property of the compost particles, namely the fragile physical property of strength, is compensated by the synthetic resin, and the fragile physical property of the synthetic resin (PE, PP or PET), namely the physical property of not rotting for hundreds of years, is compensated by the compost particles, thereby minimizing environmental pollution such as atmospheric pollution, soil pollution, water pollution and the like.
As for the antibacterial agent, in order to destroy various bacteria contained in compost particles, volcanic ash having a far infrared ray wavelength of 93% to 94% and having an alkaline component of 3 to 4ppm of germanium, air purification, sterilization, heavy metal purification, malodor removal, odor removal, neutralization toxicity and the like are prominent, and various bacteria present in animal manure, pig manure and chicken manure can be destroyed to be used more safely, and if it is less than 5wt%, the sterilizing effect is lowered, and thus it is limited to 10wt% or less, which is an antibacterial maximum.
As the binder, in view of the strong bond between the compost particles and the synthetic resin, maleic Anhydride (Maleic Anhydride) may be used, which enables the synthetic resin to fuse with the compost particles upon hot mixing and hot stirring, and if it is less than 2wt%, the bond between the compost particles and the synthetic resin cannot be maintained, and if it is about 3wt%, the bond between the compost particles and the synthetic resin will be maintained at a maximum, so that it is most preferable.
As for the dispersant, in order to minimize an error caused by shrinkage when various agricultural and livestock products or industrial parts are hardened after injection molding, extrusion or molding using a tray formed by combining compost particles with synthetic resin, that is, in order to minimize shrinkage, dolomite powder, which is contained in the compost particles and the synthetic resin by its inherent components CaO and MgO, may be used, and after preparing the tray, it plays a role of minimizing shrinkage when manufacturing the industrial parts, and shrinkage is reduced when less than 10wt%, and shrinkage is optimal when not more than 20wt%, and thus is most preferable.
As the slip agent, when various agricultural and livestock products or industrial parts are molded by injection molding, extrusion or molding using a tray formed by combining compost particles with a synthetic resin and then hardened, an amide slip agent having a neutral structure in which a Hydroxyl (Hydroxyl) group is substituted with an Amino (Amino) structure and having a high melting point of an amide series synthesized from fatty acids can be used in order to improve the surface smoothness and facilitate release thereof.
For example, the amide-based slip agent may be erucamide (erucamide), oleamide (Oleamide), behenamide (behenamide), stearamide (stearamide), stearylstearamide (stearyl stearamidel), stearylerucamide (stearyl erucamide), or oleyl palmitamide (oleylpalmityl amide), and such an amide-based slip agent is contained in compost particles and synthetic resin to form a tray, and is most preferable when an industrial part is produced, it is easy to mold, and if it is less than 0.5wt%, it is difficult to mold, and if it is not more than 1wt%, it is most easy to mold.
The acrylic powder has properties similar to those of the synthetic resin component, so that the binding with the compost particles is easy, and if it is less than 0.1wt%, the binding with the compost particles is not affected, and if it is not more than 1wt%, the binding with the compost particles is optimal, so that it is most preferable.
In order to prevent the tray from being damaged by water during long-term storage by forming a coating layer after the tray is produced, liquid paraffin may be used, and if the liquid paraffin is less than 0.5wt% and the coating force is not more than 1wt%, the coating force of the tray is most preferable.
Fig. 1 is a process diagram showing a method of manufacturing the environment-friendly low-carbon degradable antibacterial material of the present invention, and fig. 2 is a process diagram showing a process of manufacturing livestock manure into compost particles, which is adopted in the method of manufacturing the environment-friendly low-carbon degradable antibacterial material of the present invention.
The manufacturing method of the environment-friendly low-carbon degradable antibacterial material is shown in figure 1, and comprises the following steps: mixing, stirring, fermenting, post-ripening and drying livestock manure together with sawdust, a microorganism culture medium and a microorganism for composting, pulverizing to form compost particles (S10), and thermally mixing and extruding the compost particles together with synthetic resin, an antibacterial agent, a binding agent, a dispersing agent and a slip agent, and cutting the compost particles to form a tray (S20).
The environment-friendly low-carbon degradable antibacterial material is prepared as follows and is used for realizing injection molding, extrusion or forming of agricultural and aquatic livestock products or industrial products, automobile parts or various industrial containers, and the like, and through the product, not only is water resistant and impact resistant, but also the service life is ensured, and the environmental pollution caused by incineration and even degradation can be reduced to the greatest extent: the step (S10) of forming compost particles by mixing, stirring, fermenting, post-ripening and drying livestock manure together with sawdust, a microbial culture medium and a microorganism for compost decomposition enables active degradation of livestock manure by stirring and fermenting the sawdust and the livestock manure together with the microbial culture medium and the microorganism for compost decomposition, and further enables easy combination with synthetic resin by removing moisture while further fermenting and degrading by post-ripening and drying, and the step (S20) of eradicating bacteria with an antibacterial agent while mixing and combining the compost particles formed by pulverization with synthetic resin with a binder, minimizing shrinkage rate at the time of product molding with a dispersing agent, and easily performing demolding at the time of product molding with a slip aid, forming a tray by heat mixing and extruding and cutting.
More specifically, the step S10, as shown in fig. 2, includes: a step (S11) of mixing livestock manure with sawdust, a microorganism culture medium and a microorganism for composting to prepare a compost mixture, a step (S12) of injecting air into the compost mixture and stirring the mixture to prepare a compost ferment, a step (S13) of post-ripening the compost ferment to prepare a post-ripe compost, a step (S14) of drying the post-ripe compost to prepare a compost dried material, and a step (S15) of pulverizing the compost dried material to prepare compost particles.
After livestock manure is mixed with sawdust, a microorganism culture medium and a microorganism for composting to prepare a compost mixture, air is injected into the compost mixture and stirred to prepare a compost ferment, and when stirred, the compost ferment can be uniformly fermented by the air, and after-ripening of the compost ferment in a storage, namely, a compost after-ripening product which is cured again and fully fermented is prepared, and then the compost is dried to form a compost dry product, and the compost dry product is crushed to form compost particles, so that the compost ferment can be easily combined with synthetic resin.
Wherein the moisture content of the compost mixture is 50% to 70% in the step S11, the compost mixture is fermented for two months to contain 40% to 45% of the moisture content in the step S12, the compost after-ripening substance is after-ripened for two months to contain 35% to 40% of the moisture content in the step S13, the compost after-ripening substance is dried to contain 5% to 10% of the moisture content in the step S14, and the compost particles are crushed to have a size of 70 to 90 meshes in the step S15.
Specifically, most of the livestock manure is composed of moisture, and in the present invention, sawdust is added to maintain the moisture content at 50% to 70%, wherein if the moisture content is less than 50%, the sawdust is too much to be easily bonded to the synthetic resin, and if the moisture content is more than 70%, fermentation and post-maturation are not easy to occur, which is not preferable.
Thereafter, the compost mixture is sufficiently fermented for two months to reduce the moisture content to 40% to 45% to prepare a compost fermented product, and then the compost fermented product is sufficiently post-matured in a storage for two months to prepare a compost post-matured product having a moisture content of 35% to 40%, and then the compost post-matured product is dried to prepare a compost dried product having a moisture content of 5% to 10%, and then pulverized to 70 to 90 mesh, so that it can be easily combined with synthetic resin.
In the step S10, the microorganism medium is a mushroom medium, and in the step S10, the microorganism for composting may be Bacillus or Lactobacillus.
The mushroom culture medium enables the livestock manure mixed into the sawdust to ferment and degrade, and the bacillus and lactobacillus also promote the fermentation of the livestock manure mixed into the sawdust, so that the livestock manure is degraded more easily.
Further, in the step S20, acrylic powder is added to the compost particles, and the acrylic powder is easily bonded to the compost particles by utilizing properties similar to those of the synthetic resin component, and further, in the step S20, oil such as liquid paraffin is added to the compost particles, and a coating layer can be formed when the tray is formed, thereby overcoming the phenomenon of being easily damaged by water during long-term storage.
In addition, in the step S10, the compost particles may include 66wt% to 75wt% of livestock manure, 10wt% to 17wt% of sawdust, 11wt% to 17wt% of a microorganism culture medium, and 0.1wt% to 0.7wt% of a microorganism for composting.
If the livestock manure is less than 66wt%, the efficiency of forming the tray is lowered, and if it is more than 75wt%, it is not preferable to contain too much moisture; if the sawdust is less than 10wt%, it is difficult to dilute the moisture of the livestock manure, and if it exceeds 17wt%, the component ratio of the livestock manure will be relatively lowered, and the efficiency of forming the tray will be lowered; if the microbial culture is less than 11wt%, the fermentation rate will be reduced, and if it exceeds 17wt%, the sawdust will be excessively decomposed, which is not preferable; if the amount of the microorganism for composting is less than 0.1wt%, the fermentation rate and the rate of composting are lowered, and if it exceeds 0.7wt%, the sawdust is excessively decomposed, which is not preferable.
In the step S10, livestock manure comprises 50-58 wt% of cow manure, 2-8 wt% of pig manure and 6-15 wt% of chicken manure.
Cow dung is abundant in fiber, if less than 50wt% of the composition ratio of the pig dung and the chicken dung with relatively less fiber is increased to be undesirable, and if more than 58wt% of the composition ratio of the pig dung and the cow dung, which are main causes of environmental pollution, is reduced to be undesirable; considering the high moisture content of pig manure, the limit is at least 2wt% and at most 8wt%; furthermore, due to the high moisture content of chicken manure (although less than pig manure), it is limited to a minimum of 6wt% and a maximum of 15wt%.
In the step S20, 30 to 50 weight percent of compost particles, 30 to 50 weight percent of synthetic resin, 5 to 10 weight percent of antibacterial agent, 2 to 3 weight percent of bonding agent, 10 to 20 weight percent of dispersing agent, 0.5 to 1 weight percent of slip agent, 0.1 to 1 weight percent of acrylic powder and 0.5 to 1 weight percent of oil are subjected to hot mixing, extrusion and cutting to form the tray.
The compost particles formed by mixing, stirring, fermenting, post-ripening and drying livestock manure as an environmental pollution source with sawdust, a microorganism culture medium and composting microorganism together form a proportion of 30-50 wt% with synthetic resin as an environmental pollution source, so that the fragile physical property of the compost particles, namely the fragile physical property of strength, is compensated by the synthetic resin, and the fragile physical property of the synthetic resin (PE, PP or PET), namely the physical property of not rotting for hundreds of years, is compensated by the compost particles, thereby minimizing environmental pollution such as atmospheric pollution, soil pollution, water pollution and the like.
Preferably, in the step S20, the thermal mixing is performed at a temperature of 70 to 80 ℃ for 15 to 30 minutes, so that the mixing of the compost particles with the synthetic resin becomes easy, wherein if the temperature is lower than 70 ℃ and the time is less than 18 minutes, the compost particles and the synthetic resin cannot be smoothly mixed, and therefore, it is not preferable, and if the temperature is higher than 80 ℃ and the time is higher than 30 minutes, the phenomenon of melting of the synthetic resin occurs before the synthetic resin is not uniformly mixed to the compost particles, and therefore, it is not preferable.
