The present invention relates to a rod end having an antimicrobial function, and more particularly, a plurality of rod box holders (also called "liners") formed in a rectangular box shape having an open front surface are connected to each other in a checkerboard shape. The front of the box is composed of a rod end that is installed to open and close the door, and the bag end box is formed of ABS resin material with natural antimicrobial agent made of plastic shell powder, which causes condensation due to temperature difference between inside and outside of the end. By means of an antimicrobial function to prevent the decay or deterioration of the remains or artifacts in storage by inhibiting the growth of microorganisms (anaerobic bacteria), such as mold, even if moisture occurs in the interior of the enclosure.

In general, Bong'andan means to seal and seal the remains and artifacts left after cremation of the deceased, and as the demand for crevices by cremation increases more recently than burial by burial, various forms and structures A bonandan with a proposal has been proposed.

The present applicant is arranged to install a plurality of bin box holders (also called "liners") formed in the form of a checkerboard in order to meet the rapidly increasing demand for ossuary bones connected to each other and connected to each bag holder box After installing the door frame bar to cover the connection part, after developing the sealing eye end configured to be detachably installed as a corner plate fixing the square plate-shaped door in front of each of the enclosure box, and patented this patent and patent No. 0510083 It was registered as No. 0847095.

However, the conventional bonandan is formed by sealing the box box made of aluminum or stone plate or injection molded of synthetic resin material, the door frame bar is formed of synthetic resin material, the door is made by smoothly processing the front and rear surfaces of the stone plate As it is formed, when the door is installed on the front of the door, the rear of the door keeps a smooth flat surface, but the front of the door closet which is in contact with the door is not as smooth or flat as the rear of the door. There is a small gap in the contact area of the front of the storage box. As a small gap formed in the contact area, small insects such as ants or spiders enter and exit the enclosure, and the interior space becomes messy. There was a problem that moisture is introduced and the ashes or bone meal easily decay.

2 and 3 is a view showing the results of comparative antimicrobial experiments of the box box and the general ABS used in the bag end of the present invention.
Figure 4 and Figure 5 is a view showing the comparative antimicrobial experiment results according to the ratio of the natural antibacterial agent of the box box and the general ABS used in the bag end of the present invention.

Hereinafter, the present invention for achieving the above object will be described in detail with reference to FIGS. 1 to 5.

As shown in FIG. 1, the rod eye end 1 having the antimicrobial function according to the present invention is provided with a plurality of bag holders 2 formed in the shape of a rectangular box having an open front connected in a checkerboard shape, respectively. The front door of the enclosure box (2) of the door (3) is installed to open and close.

At this time, the bag box (2) is formed of an ABS resin material is added to the natural antibacterial agent made of plastic shell powder, the bag box (2) is made of an ABS resin material is added to the natural antibacterial agent made of plastic shell shell powder. The reason for the formation is that ashes or relics that are being stored by suppressing the growth of microorganisms (anaerobic bacteria) such as molds, even if moisture is generated inside the enclosures of the enclosures 2 due to condensation due to internal and external temperature differences of the enclosures 1 This is to effectively prevent corruption or deterioration.

Conventional bag box is made of most ABS resin material, ABS resin itself does not have a function to prevent the growth of bacteria, in order to give an antibacterial function to suppress the growth of microorganisms (anaerobic bacteria) such as fungi. It is necessary to add an additive to have, and the present applicant has examined various antimicrobial agents to select the most suitable additive for the bag box (2) made of ABS resin material.

Additives added to the synthetic resin to prevent bacterial propagation are largely divided into organic (including organic metal) and inorganic, depending on the action is also divided into sterilization and antibacterial.

The organic antimicrobial agent mainly utilizes the effect of releasing or migrating drugs, and acts more like an antimicrobial to prevent the formation of colonies of bacteria than sterilization. Such organic antimicrobial agents are synthetic resins when processed in synthetic resins. The rapid exposure from the surface of the product prevents bacterial growth, which is relatively inexpensive, does not significantly affect the color of the synthetic resin product, and is easy to process, while its rapid dissolution results in weak durability. In synthetic resins under high temperature working conditions, it is impossible to apply due to thermal decomposition of organic antimicrobial agents, and there are disadvantages such as harmfulness to human body and environment.

Such organic antimicrobial agents are used in synthetic resins, which are suitable for soft PVC, polyolefin, etc., which have a relatively low working temperature.The representative organic antimicrobial agents currently on the market are organic metals, arsenic (As), and OBPA (oxybisphenox arsine). Almost all of them are used in bathroom sealants, and due to long-term toxicity problems, chlorine-based triclosan or pure oil isothiazalone are used as substitutes, but OBPA is still very inexpensive. have. In addition, rather than killing the bacteria directly, the organic antimicrobial agent is mainly antibacterial action to prevent the bacteria from growing on the surface by rapid elution.

On the other hand, the inorganic antimicrobial agent is mainly used metal ions such as silver, copper, zinc, in the case of copper is only applied to building materials, etc. due to the problem of discoloration due to toxicity and oxidation, and practically silver is the most applied. It is becoming. In the case of silver ions, they interfere with the movement of energy by binding to the cell wall, or when they penetrate into the cell, they bind to the sulfur component of the protein, thereby inhibiting the action of the enzymes that cause metabolism to kill bacteria.

Metal ions are ionized from the metal component impregnated in the synthetic resin and eluted to the surface of the synthetic resin. Since silver particles are eluted at a concentration of several ppb, most of them have a continuous effect until the durability of the synthetic resin. It is eluted with very little ppb (1 billion grams), but it shows effective bacterial growth prevention and killing effects.

The inorganic antimicrobial agent has the advantages of excellent durability because of its slow dissolution rate, no environmental or human harmful effects due to the small amount of dissolution, and excellent thermal stability, while low dispersibility in the polymer resin and inducing color change. It has the disadvantage of being relatively expensive.

Recently, the application of nanoparticles rather than bulk particles is rapidly increasing due to the development of nanotechnology. In the case of using nanoparticles, dissolution can be maximized by increasing the specific surface area to mass, so that the same effect can be achieved even in a small amount. Therefore, the price can be drastically lowered.

Actually, when added to the synthetic resin to be more than 2500ppm exhibited the antibacterial and bactericidal effect by elution, the same effect is exhibited even at the concentration of 100ppmm by using nanoparticles. However, the processing of nanoparticles with polymers is still under research and development, and the effective concentrations showing antibacterial and bactericidal effects vary depending on the degree of technology development, and research and development on dispersion of polymers in polymer resins is urgent. to be.

For reference, there are three methods for analyzing the performance of antimicrobial products: inhibition method, flask method, and film adhesion method.

Inhibition method (Halo test, Zone of Inhibition test, AATCC 147) is a method of observing how much inhibition bands are produced around the specimen by placing the specimen on the nutrient medium coated with bacteria. It is evaluated that organic matter flows around the specimen by elution and suppresses bacterial propagation. The inhibition zone is expressed in mm, and the inorganic antibacterial agent is not suitable for the inhibition zone because the elution is mainly present on the synthetic resin surface. Since the antimicrobial test method is used to familiarize with the test of the organic antimicrobial agent, the inorganic antimicrobial agent is often used as a standard even though the above method is not appropriate.

Shake Flask test (ASTM E2149-1) is a method established on the basis of analysis of textile products, and is suitable for analysis of products using organic antimicrobial agents with excellent dissolution properties or products using inorganic antibacterial agents with excellent dissolution properties. In the culture medium in which the bacteria are cultured, the antimicrobial product sample is put in and then cultured for a certain time to measure the viable bacteria. The antimicrobial activity of the sample with bulk silver particles does not appear properly as a method suitable for fabrics rather than general synthetic resin products.However, when the nanoparticles are treated, the exposed area is increased due to the increase of the surface area and the elution is easier than the bulk particles. Has excellent antibacterial activity.

Film attached method (ISO 22196, JIS Z 2801) is the most suitable method for the analysis of the antimicrobial activity of synthetic resin products using inorganic antimicrobial agent in which migration of metal particles is limited to the surface of synthetic resin. This is a method of measuring the number of viable cells after inoculation and covering with a film. When the antimicrobial activity is effective by this method, the numerical value is 99% or more (log value = activity value 2), and in the case of commercial products, in general, an activity value of 4 or more is often required.

Through the review process as described above, the present applicant has no side effects and harmless to the human body, compared to the conventional chemically synthesized organic antimicrobial agent, and can solve the disadvantages such as dispersibility decrease and color change of the inorganic antimicrobial agent. As an additive, a natural antimicrobial agent made of calcined shell powder is adopted as the most suitable additive for ABS resin.

Natural antimicrobial agent made of fired shell powder used in the present invention is an eco-friendly fired calcium ionized shell calcium fired from shells of 100% natural materials produced in clean seas, and salt, organic matter, and contamination of raw materials with special washer using ground water. It is known that the material is completely removed and then fired at a high firing temperature (1200 ° C.) and then ground to a uniform particle size.

Experimental results of the antimicrobial performance of the sealed box holder made of ABS resin containing the natural shell powder of the plastic shell powder will be described with reference to Table 1 and FIGS. 2 and 3 as follows.

The experiment was commissioned by the Korea Institute of Construction and Environmental Testing, Seocho-dong, Seocho-gu, Seoul, Korea, with a 5cm × 5cm test piece (unclosure box specimen, antibacterial ABS) and a 5cm × 5cm control piece (BLANK, general ABS) for Escherichia coli ATCC 8739. ) And Staphylococcus aureus ATCC 6538P strains were tested for bacterial reduction rate through the KCL-FIR-1003: 2011 test method.

According to the test results, the test box box made of ABS resin containing the natural antimicrobial agent of fired shell powder showed a reduction of 99.9% of bacteria after 24 hours in case of Escherichia coli, and in case of Staphylococcus aureus. After a while, the number of bacteria decreased and showed a reduction rate of 99.9%. Through these experimental results, it was clearly confirmed that the drop box holder (2) used in the bag end of the present invention had excellent antibacterial function.

In addition, the natural antimicrobial agent of the calcined shell powder has a particle size of 10 ~ 20㎛, added in a proportion of 1.5 ~ 5wt% relative to the total weight of the ABS resin.

In this case, the reason for limiting the particle size of the natural antimicrobial agent of the fired shell powder to 10 ~ 20㎛ is that when the size of the natural antimicrobial agent of the fired shell powder is less than 10㎛, the dispersibility is lowered to give a uniform antimicrobial effect If it exceeds 20 μm, the injection molding of ABS resin may expose the surface and cause injection defects.

The reason for adding the natural antimicrobial agent of the fired shell powder at a ratio of 1.5 to 5 wt% based on the total weight of the ABS resin is that when the addition ratio of the natural antimicrobial agent of the fired shell powder is less than 1.5 wt%, Effective antibacterial function can not be expected, and when it exceeds 5wt%, there is a high possibility that defects may occur during injection molding of ABS resin, and the workability is significantly reduced.

In addition, the results of testing the antimicrobial performance of the enclosure box according to the addition ratio of the natural antimicrobial agent of the plastic shell powder will be described with reference to Table 2 and Figures 4 and 5.

The experiment was commissioned by the Korea Textile Technology Research Institute, Jungwon-gu, Seongnam-si, Gyeonggi-do, Korea. The test was conducted on JIS specimens for Escherichia coli ATCC 8739 and Staphylococcus aureus strains. The bacterial reduction rate was tested through the Z 2801 test method.
