Manufacturing method of foam disinfectant using silver ion water {METHOD FOR PREPARING OF FOAMED GERMICIDE USING SILVER ION WATER}

The present invention relates to a method for producing a foam disinfectant using silver ionized water, and more specifically, contains silver ionized water to have an antibacterial effect, has a porosity of 10 to 20% and exhibits excellent solubility in water, It relates to a method for producing a foam disinfectant using silver ionized water capable of securing remarkably excellent stability even under the

The foam type disinfectant refers to a tablet form in which the organic acid decomposes carbonate on its own when in contact with water and generates carbon dioxide (CO ₂ ) gas to dissolve the main component and other auxiliary components.

On the other hand, potassium peroxide sulfate (monopersulfate compound) has a function as a strong non-chloride oxidizing agent that can be applied to various industrial fields as well as a general disinfectant. During the leather manufacturing process, tanning chemical agents, denture cleansers, swimming pool oxidants, circuit board etchants, pulp recycling, wood cleaning ), veterinary, etc., and can be applied where strong oxidizing power is required but relatively safety is required.

However, since potassium peroxide sulfate takes a granular form close to powder, there is a problem in that it is not easy to completely dissolve without a dissolution device, as well as a safety aspect for handlers when handling the powder.

Therefore, in order to compensate for the above problems, the present inventors have recognized that it is urgent to develop a method for preparing a foam disinfectant that has improved stability and is easily completely dissolved, and has completed the present invention.

[Method of manufacturing foam disinfectant using silver ionized water]

The present invention provides a method for preparing a foam disinfectant using silver ionized water, including the following steps.

(S1) preparing a first mixture by mixing sodium bicarbonate and silver ionized water;

(S2) preparing a second mixture by adding citric acid and starch to the first mixture; and

(S3) molding the foamed disinfectant in the form of pellets from the second mixture with a tablet press.

The step (S1) is a step of preparing a first mixture, and may include the following steps.

(S1A) mixing sodium bicarbonate and silver ionized water; and

(S1B) preparing a first mixture in powder form by heating the mixture at 40 to 60 °C.

The silver ionized water may be prepared at a concentration of 0.1 to 10 ppm through electrolysis by adding silver (Ag) to pure water (H ₂ O). When the concentration of silver in the silver ionized water exceeds 10 ppm, the foamed disinfectant finally prepared may be easily crumbled due to the excessive silver content, making it difficult to maintain the pellet form.

In the step (S1A), 700 to 900 g of sodium bicarbonate may be mixed with 100 L of silver ionized water. When the sodium hydrogen carbonate is included in less than 700 g, the foamability may be significantly reduced, and when the sodium hydrogen carbonate is included in more than 900 g, the color of the finally prepared foam disinfectant may be discolored. It may be most preferable that 700 to 900 g of sodium bicarbonate is included for 100 L of silver ionized water.

The step (S2) is a step of preparing a second mixture, and a second mixture in powder form may be prepared by including 700 to 900 g of citric acid and 50 to 150 g of starch with respect to the first mixture.

The step (S3) is a step of finally preparing the foam disinfectant according to the present invention, and the second mixture can be molded into a foam disinfectant in the form of pellets at a pressure of 3 to 150 Bar using a tablet press.

The foam disinfectant may have a porosity of 10 to 20% to exhibit excellent solubility. More specifically, it may have improved solubility when the solution permeates and dissolves in the pores present in the foam disinfectant.

The term "porosity" used in the present invention is the ratio occupied by the gaps between the particles, and when the curvature is applied to the present invention, it means the ratio of the voids (gaps) between the foamed disinfectant particles and the particles.

The foamed disinfectant may have stability for 6 months or more when stored in an airtight container at a temperature of 40° C. and a relative humidity (RH) of 75%.

Additional additives such as surfactants, adjuvants, fragrances, binders, antibacterial agents, colorants, and fragrances may be added to the foamed disinfectant.

The foamed disinfectant prepared according to the present invention contains silver ionized water, so it has an antibacterial effect, has a porosity of 10 to 20%, shows excellent solubility in water, and can secure remarkably excellent stability even under harsh conditions. .
