Abstract

A method for preparing a nanosilver-containing antibacterial ink is provided to produce the functional ink having sterilizing or antibacterial functions and a glass scattering prevention function even without deteriorating the quality of ink. A method for preparing a nanosilver-containing antibacterial ink includes the steps of: preparing acrylic resins having a solid content of 50% by mass by synthesizing an acrylic elastomer resin containing BMA monomer and isocyanate resin as main materials in polyglycol monoethyl ether acetate at 140 °C for about 9-10 hours; adding 2-3% of a dispersant to 80-90% of the prepared acrylic resin and mixing the admixture; adding 10-20% of a pigment or aluminum paste, pearl powder, etc, 2-3% of an antifoaming agent and a leveling agent, and 1-2% of an anti-discoloring agent to the mixture, and dispersing the admixture at high speed to prepare an ink. To provide an antibacterial property, 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 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 a solution containing nano silver particles impregnated at 10% concentration of 1 to 5 nm is mixed with ink and printed on a glass plate to transfer images through printing and at the same time antibacterial function and glass When broken, the present invention relates to an antimicrobial ink containing nano silver and a method of using the same, wherein the nano-silver can be given safety at risk due to scattering.

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, in order to prevent scattering when antimicrobial agents such as antimicrobial nano silver are mixed in the glass itself or to break the glass, a safety film is attached to the inside or one side of the glass to prevent scattering, which is a huge burden in terms of cost. to be.

Accordingly, an object of the present invention is to realize a beautiful design by producing a functional ink that has a sterilization, antibacterial function, and anti-scattering function of glass without degrading the ink quality of the silk screen ink of the nano silver compound and printing on the glass plate material The manufacturing cost is also provided to provide a method for producing an antimicrobial glass plate material which is inexpensive, sustainable and harmless to the human body.

Another object of the present invention is to provide 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 is made of a silkscreen ink composed of an oil-based acrylic elastomer resin, an ink composed of a nanonized silver compound and other additives, and the like to form a functional glass sheet by silkscreen printing on the glass sheet.

Acrylic elastomer resin mainly composed of BMA monomer and Isocyanate resin in polyglycol monoethyl ether acetate was synthesized at 140 ℃ for 9 ~ 10 hours to prepare acrylic resin of 50% by weight of solid content (all percentage by weight).

80 ~ 90% of the acrylic resin thus prepared is mixed with 2 ~ 3% dispersant and then mixed with 10 ~ 20% of pigment, aluminum paste, pearl powder, etc. (contents and ingredients may vary depending on the color), An antifoaming agent, 2 ~ 3% leveling agent additive, and 1 ~ 2% of discoloration inhibitor are added to produce high speed ink.

In this case, if 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 plate.

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 the adhesion promoter is Methoxy silane, which is mixed with 10% of the ink content.

Thus, the antimicrobial and glass adhesiveness-provided inks were prepared and printed on the back surface of the glass plate through silk screen printing and dried at 70 to 80 ° 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% of the results of the bacterial growth test (FITI test report H217-06-00019) jointly from Kangwon National University and Korea FITI Testing Institute.

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 of antimicrobial safety, antibacterial, anti-fungal, deodorant, far-infrared emission, safety, etc. through the silk screen on the back of the glass plate, and these features last for a long time It has an excellent effect of being friendly to and 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.
