Abstract

A method for preparing a nanosilver-containing antimicrobial ink is provided to produce a functional ink which has sterilizing or antibacterial functions even without deteriorating the quality of ink and embodies a fine design on a glass plate. A method for preparing a nanosilver-containing antimicrobial ink includes the steps of: mixing 60-70% by mass of acrylic oils with 2-3% of a dispersant; adding 20-30% of a pigment, glass beads, or pearl powder, etc, 2-3% of an antifoaming agent and a leveling agent, and 1-2% of an anti-discoloring agent to the mixed acrylic oils; and dispersing the admixture at high speed to prepare ink. To impart an antibacterial property to the ink, 0.3% of a nanosilver solution having a nanosilver size of 1-5 nm and a nanosilver concentration of 10% is added to the ink and uniformly mixed in an agitator.

Description

The antibiosis ink by nano-silver and using process}

The present invention relates to a silk screen ink containing nano silver, and a solution containing nano silver particles impregnated at a concentration of 10% of 1 to 5 nm in ink to be printed on a glass plate to impart antimicrobial function simultaneously with image transfer through printing. It relates to an antimicrobial ink containing nano silver and a method of use.

In general, silkscreen printing is widely used unconsciously on glass sheets, and is prepared by mixing a plurality of mixtures, and contains a small amount of contaminant in its composition. For this reason, its use requires considerable attention, but it is true that it is not so.

In particular, when the glass plate is used as a building interior material such as an air conditioner, a refrigerator, a kimchi refrigerator, an air cleaner, a medical institution such as a hospital, an indoor interior of a jjimjilbang, a school, or the like, It can be a social problem such as an infection problem.

In order to prevent the infection of pathogenic bacteria, antimicrobial agents having bactericidal properties are added to the glass or regularly sterilized, cleaned and cleaned.

As described above, in the case of antimicrobial agents using general organic compounds, the antimicrobial had a limit on the persistence of the antimicrobial agent, and since the antimicrobial agent itself is composed of an organic chemical agent, it harms the human body itself. In addition, when an antimicrobial agent such as antimicrobial nano silver is mixed with the glass itself, it is a huge burden in terms of cost.

Therefore, an object of the present invention is to produce a functional ink that has a sterilization or antibacterial function without reducing the ink quality by the silk screen ink of the nano silver compound to print on the glass plate material to realize a beautiful design and at the same time low cost and continuous manufacturing And to provide a method for producing an antimicrobial glass plate material harmless to the human body.

Accordingly, the present invention provides a method for printing a glass plate material that can give an external aesthetic and stability by using the antimicrobial ability and persistence of nanosilver.

The present invention concludes that a silkscreen printing on a glass plate is made of a silkscreen ink composed of an oil-based acrylic resin, a nanonized silver compound, and other additives to form a functional glass plate.

Add 2 ~ 3% of dispersant to 60 ~ 70% by weight of acrylic oil (hereafter, all percentages by weight), and then mix 20 ~ 30% of pigment, glass bead or pearl powder. It may be slightly different), the antifoaming agent, the leveling agent additive 2 ~ 3%, discoloration inhibitor 1 ~ 2% in the high-speed dispersion to prepare the ink.

At this time, if the antifoaming agent and the refrigerating agent are used less than the reference content, bubbles may be generated and an unprinted part may be generated, and when used excessively, the adhesion of the glass plate may be reduced.

In order to impart antimicrobial properties to the ink thus prepared, the nanosilver solution is mixed and silkscreened onto the glass plate.

Nanosilver solution for imparting antimicrobial is added to the ink by 0.3% to 10% concentration of nanosilver solution in the size of 1 ~ 5nm and mixed well with a stirrer.

Thus, the antimicrobial and glass adhesiveness-provided inks were prepared and printed on the back side of the glass plate through silk screen printing and dried at 600 to 700 ° C. for 30 minutes or more to form an antimicrobial printing film.

In this regard, the present invention showed that the bacterial reduction rate reached 99.9% of the bacterial growth test (FITI test report H217-06-00019) jointly from Kangwon National University and Korea FITI Testing Institute in order to verify antibacterial activity.

As described above, the antimicrobial glass plate material through silk screen printing is to be expressed in various forms of external patterns to give an external aesthetic sense.

The present invention is not limited to the above-described specific preferred embodiments, and various modifications can be made by any person having ordinary skill in the art without departing from the gist of the present invention claimed in the claims. Of course, such changes will fall within the scope of the claims.

As described above, the present invention has a complex function such as antibacterial, antiseptic, anti-mildew, deodorant, far-infrared radiation, and the like for the production of antimicrobial glass through the silk screen on the back of the glass plate, and this feature is sustainable for a long time It has an excellent effect that it is beneficial to the human body. In addition, it is expected that the manufacturing process is simple, the aesthetic effect is excellent, the manufacturing cost is also low, and the industrial contribution is large.
