Description

Inorganic antibacterial resin chip using silver, charcoal and synthetic resin and its manufacturing method {Mineral antibiotic rosin chip by using silver, charcoal, plastics and its manufacturing process}

The present invention is mixed with the crushed charcoal powder in purified silver, dried, and then pulverized again to obtain a silver ion antimicrobial charcoal, and evenly mixed with the silver ion antibacterial charcoal synthetic resin and then extruded cut to obtain an inorganic antibacterial resin chip In addition, the inorganic antimicrobial resin chip is put in a nylon net to be used for sterilization of water tanks or industrial wastewater or extruded to be used as a food storage container or a packing film so that the freshness of food can be maintained for a long time.

Silver (銀) is a natural antibiotic that was produced by taking a silver solution, and the results of the experiment so far (銀) is reported to kill all the single cell germs on the ground.

Charcoal has been used for many purposes by our ancestors since ancient times, and the surface area of 1g of charcoal is about 100 pyeong, which is reported to have excellent adsorptive power.

There are many theories that charcoal has many holes and it absorbs bacteria, viruses, and toxins. There is also a theory that carbon contains a lot of negative electrons, which prevents material from decaying.

In addition, silver nitrate was used to disinfect and sterilize water, citric acid was used to remove P. aeruginosa, and zinc chloride was used as a wood preservative.

However, antibiotics used for sanitary treatment mainly consist of organic compounds originating from quaternary ammonium, and organic mercury, organic chromic acid, and copper compounds, which are regulated by law because of their toxicity and genetic variation.

Therefore, in domestic sewage treatment plants, sanitary wastewater treatment plants, and food factory wastewater treatment plants, chlorine sterilization is mandatory to sterilize E. coli in wastewater discharge, but chlorine causes carcinogens and destroys the ecosystem. There was a problem.

In order to correct the above problems of the present invention, silver ions are mixed with pulverized charcoal powder, dried and pulverized to obtain silver ions antibacterial charcoal, and the silver ions antibacterial charcoal is mixed with a resin and then extruded to cut inorganic antibacterial resin chips. It is to be used for various purposes by using the antimicrobial chip.

As an example, put an inorganic antibacterial resin chip in a nylon net and put it in the waste water, so that E. coli or bacteria are sterilized. If it is put in a water tank or an aquarium of fish, it inhibits the growth of E. coli and Vibrio bacteria and sterilizes them.

In addition, by inserting the antimicrobial resin chip of the present invention into an injection molding machine to make an antimicrobial plastic container or to produce and use an antimicrobial film for food packaging to reduce the use of preservatives used for the preservation of food and at the same time to prevent corruption of food. Long-term freshness can be maintained.

Oxygen bound to silver, charcoal (carbon) and resin is partially converted into active oxygen (O ²⁺ , O ^2- , O) by the catalytic action of antibacterial metals, and the active oxygen is converted into ozone, hydrogen peroxide, chlorine, etc. Strong sterilization will be.

Hereinafter, an embodiment of the present invention will be described in detail by process.

(Example 1)

1st process

A silver solution is obtained by melting 100 g of silver ingot, sintering the molten silver into water, placing it in a dissolution tank, and heating it while gradually adding silver nitrate.

20 g of sodium aluminate is added to the silver solution to neutralize the acid, filtered, concentrated by evaporation, and cooled to purify the small intestinal silver.

2nd process

100 g of the silver obtained in the first step was dissolved in 300 ml of water, and then 500 g of oak charcoal crushed into 1000 mesh were mixed and dried, and the dried crystals were pulverized to about 1000 mesh to obtain silver ion antibacterial charcoal. .

3rd process

After mixing and stirring 600 g of the silver ion antibacterial charcoal obtained in the second step to 5000 g of PE resin, the stirred resin is put into an extruder to be extruded and cut to prepare a small inorganic antibacterial resin chip such as sand.

(Example 2)

1st process

A silver solution is obtained by melting 100 g of silver ingot, sintering the molten silver into water, placing it in a dissolution tank, and heating it while gradually adding silver nitrate.

20 g of sodium aluminate is added to the silver solution to neutralize the acid, filtered, concentrated by evaporation, and cooled to purify the small intestinal silver.

2nd process

100 g of the silver obtained in the first step was dissolved in 300 ml of water, and then 500 g of oak charcoal crushed into 1000 mesh were mixed and dried, and the dried crystals were pulverized to about 1000 mesh to obtain silver ion antibacterial charcoal. .

3rd process

The silver ion antimicrobial charcoal obtained in the second process is dissolved in water, mixed with a resin for fabric processing and then coated on the surface of the fabric, and then heat treated to obtain a fabric having antimicrobial properties by fixing the silver ion antibacterial charcoal to the fabric.

The inorganic antibacterial resin chip obtained above has the following function.

That is, oxygen bound to silver, charcoal, and resin is partially converted into active oxygen (O ²⁺ , O ^2- , O) by the catalytic action of the antibacterial metal, and the active oxygen is ozone, hydrogen peroxide, chlorine, and the like. Strong sterilization will be performed.

In addition, charcoal having many pores has an area of about 100 pyeong with a surface area of 1g, which is excellent in adsorption power, and since silver ions are substituted in many pores, the charcoal adsorption force allows the adsorption of organic matter and antibacterial effect. Excellent and deodorizing effect.

Therefore, it can also be used for various purposes by using a strong adsorption and sterilization as described above.

When the inorganic antibacterial resin chip obtained in the present invention is put in a nylon net and used in an underground water tank, a rooftop tank, an aquarium, etc., the bactericidal effect of E. coli, Vibrio bacteria, and the like is used when used in wastewater treatment of a wastewater treatment plant. Will be obtained.

The amount of the inorganic antibacterial resin chip used in the above was measured to be more than 90% sterilization in a short time and harmless to the human body when put in an amount of about 1 kg per 100 L of water.

In addition, if the antimicrobial resin film is prepared using the inorganic antibacterial resin chip obtained in the present invention and then used for food packaging, it is possible to prevent food spoilage and maintain freshness for a long time. It is beneficial because it can reduce the amount of preservatives used.

Even when molded into a plastic container using the inorganic antibacterial resin chip of the present invention and then used as a container, it is possible to keep various foods stored in the container in a fresh state for a long time.

Therefore, the present invention allows the use of inorganic antibacterial resin chips for chlorine, which has been mainly used as a conventional disinfectant, thereby reducing the risk of carcinogenesis by using chlorine as a disinfectant, as well as preventing environmental and ecosystem destruction. .

In addition, by sterilizing the necessary amount of food waste water, sanitary treatment plant, tap water tank, aquarium, etc. to sterilize, it is possible to sterilize various germs in a short time. Very advantageous.

When used as a food packaging container or film using the inorganic antibacterial resin chip of the present invention will not only prevent food corruption but also maintain the freshness of food for a long time.
