Abstract

A method for preparing a nanosilver-containing antimicrobial ink is provided to produce the antibacterial ink having sterilizing or antibacterial functions without deteriorating the quality of ink. A method for preparing a nanosilver-containing antimicrobial ink includes the steps of: (1) preparing acrylic resins having a solid content of 50wt% by synthesizing an acrylic resin containing MMA monomer as a main material in polyglycol monoethyl ether acetate at 140 °C for about 6-7 hours; (2) mixing 60-70% of the prepared acrylic resin with 3-5wt% of a dispersant; and (3) adding 20-30% of pigment or aluminum paste, pearl powder, etc, 3-5% of an antifoaming agent and a leveling agent, and 1-2% of an anti-discoloring agent to the dispersant-dispersed acrylic resin, and dispersing the admixture at high speed. To impart an antibacterial property and adhesion to the prepared ink, a nanosilver solution having a nanosilver size of 1-5 nm and a nanosilver concentration of 10% is added to the ink in a ratio of 0.3% and 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 in particular, a solution containing nano silver particles impregnated at a concentration of 10% of 1 to 5 nm in ink and printed on a glass plate to provide an antimicrobial function simultaneously with image transfer through printing. The present invention relates to a silkscreen ink containing nanosilver which can be imparted and to a method of using the same.

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.

Accordingly, an object of the present invention is to produce a functional ink that has a sterilization or antimicrobial function without degrading 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 manufacturing cost And to provide a method for producing an antimicrobial glass plate material harmless to the human body.

The present invention for realizing this object is a low temperature curable glass ink of 120 ℃ ~ 130 ℃ by mixing the particles 1 ~ 5nm high concentration nanosilver solution of 10% by the method of printing at regular intervals on the back of the glass plate material It aims to create antibacterial function at the same time as creation.

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.

Synthetic acrylic resin mainly composed of MMA monomer to polyglycol monoethyl ether acetate was synthesized at 140 ° C. for 6 to 7 hours to prepare acrylic resin having 50% by weight of solid content (hereinafter, all percentages by weight).

60 to 70% of the acrylic resin thus prepared is added 3 to 5% of the dispersant and mixed, and then 20 to 30% of the pigment or aluminum paste, Pearl Powder, etc. (content and composition may vary slightly depending on the color) , Antifoaming agent, leveling agent additives 3 to 5%, discoloration inhibitor 1 to 2% was added to the high speed dispersion to prepare the ink.

In this case, when the antifoaming agent and the leveling agent are used less than the reference content, bubbles may occur 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 and adhesion to the ink thus prepared, a mixture of nanosilver and an adhesion promoter is silkscreened onto a glass sheet.

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

The mixed solution used as an adhesion promoter is mixed with 10% mf in the ink content with methoxy silane.

Thus, the antimicrobial and glass adhesiveness-provided ink is prepared and printed on the back of the glass plate through silk screen printing, and then dried at 120 to 130 ° C. for at least 10 minutes to form an antimicrobial printing film.

In this regard, the present invention showed that the bacterial reduction rate reached 99.9% when the bacterial growth test was jointly performed at Kangwon National University and FITI Test Institute in Korea (FITI Test Report H217-06-00019).

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 these features last for a long time and are friendly to the natural environment. It has an excellent effect that it is beneficial to the human body. In addition, the manufacturing process is simple, the aesthetic effect is excellent, the manufacturing cost is also low, there is an effect such as high industrial contribution.
