In general, gold is widely used in the electrical and electronic industries such as printed circuits and semiconductors because of its inertness and high electrical conductivity. In particular, even in oriental medicine, gold has an even ingredient, has a sour taste, is free from poison, Anhon, sincerity, and five jang, five cubits, five gusts of wind and real symptoms It has been regarded as having a special effect of healing the race. In addition, gold has a detoxifying effect of absorbing and releasing various toxic substances in the body, and has a skin cleansing effect, and it is a material for skin diseases, arthritis, neuralgia, such as boils, sores, poisons, poisons, and purulents. Is being used.

Nano-nano gold (nano) with various uses and effects as described above can be easily absorbed without irritation even with a small amount of gold and can be sustained for a long time with its strong efficacy. Products and production processes are not available.

In addition, general cleaning agents are irritating to the human body depending on chemical composition, and environmental pollution and static electricity contained in the cleaning agent cause unnecessary damage to industrial and human life.

The present invention has been made to solve the above problems, the object is that the general cleaning agent is irritating to the human body and contains an antistatic property to solve the problem of environmental pollution, to reduce the damage caused by static electricity, The present invention provides a gold nano antimicrobial cleaner and a manufacturing method using the same, which contain gold nano components, and thus minerals of gold remain intact even after washing.

According to a first aspect of the present invention for achieving the above object, the first step of measuring and mixing the quantitative water into the mixer, and weighing and mixing sterile and washable ethanol at a specific gravity of 850 grams per liter into the mixer ; After the first process, the mixed water and ethanol are stirred for 5 minutes, and then slowly adding a predetermined amount of COCAMIDE DIETHANOL AMINE, a nonionic surfactant composed of palm oil fatty acid diethanol amide, which is washed. 2 courses; After the second process, the mixed non-ionic surfactant is stirred for 10 minutes, the surface coating and the antistatic agent consisting of DIMETHYL AMINOETHYL META ACRYLATE which is an anionic activator to prevent static electricity into the mixer into a certain amount 3 courses; A fourth step of stirring the mixed antistatic agent for 5 minutes and then mixing the antimicrobial agent consisting of DIPROPYLENEGLYCOL METHYL ETHER with a fixed amount in the mixer for 5 minutes after stirring the mixed antistatic agent for 5 minutes; And a fifth process of measuring and mixing antimicrobial gold nano (Au Nano) and stirring for 10 minutes after the fourth process is made.

At this time, according to an additional feature of the present invention, after the fifth process is made, the sixth process of stirring for 20 minutes after the quantitative deodorant to neutralize the odor in the mixer;

In addition, according to an additional feature of the present invention, after the sixth process is made, after taking a sample of the washing liquid mixed in the mixer and measuring the pH concentration to neutralize the pH concentration to 7.0 ± 0.5 and stirred for 20 minutes, Preferably, the method further comprises the step of filling.

According to a second aspect of the present invention for achieving the above object, the mixer consists of 60% to 67% by weight of water, 20% by weight of ethanol with sterilization and washability, and palm oil fatty acid diethanol amide for washing 2% by weight of COCAMIDE DIETHANOL AMINE, a nonionic surfactant, 5% by weight of detergent for DIPROPYLENEGLYCOL METHYL ETHER which plays an auxiliary role in washing, 3% to 10% by weight of antimicrobial Au Nano, and smell It provides a gold nano-antibacterial cleaning agent made by sequentially adding 3% weight ratio of neutralizing deodorant and stirring for a predetermined time.

At this time, according to an additional feature of the present invention, it is preferable to take a sample of the washing solution mixed with the mixer to measure the pH concentration to neutralize and fill the PH concentration to 7.0 ± 0.5.

Hereinafter, exemplary embodiments of the present invention will be described in detail with reference to the accompanying drawings.

1 is a flow chart showing a manufacturing method of a gold nano antibacterial cleaning agent according to the present invention, Figure 2 is a view of the antimicrobial activity test method of the gold nano antibacterial cleaning agent according to the present invention, Figure 3 is a gold nano antibacterial cleaning agent according to the present invention It is a figure which shows the role of the antistatic agent of antistatic.

Referring to the gold nano-antibacterial detergent manufacturing method of the present invention with reference to the accompanying FIG. 1, first, a predetermined amount of water is measured to prepare a detergent, and a mixing tank or a mixer is injected. At this time, the amount of water to be added to the mixer can be added in a variable amount of 60% to 67% compared to other components when the weight ratio of the cleaning agent, the cleaning liquid composition to 100%.

The ethanol with sterilization and washability is added to the mixer. At this time, the ethanol is mixed at a specific gravity of 850 grams based on 1 liter, and considering the amount of water, the ethanol is composed of about 20% by weight. It is preferable.

By mixing a predetermined amount of water and ethanol by the above and stirred for 5 minutes to rot well (see step S10).

Thereafter, a predetermined amount of a nonionic surfactant composed of water mixed by the stirring action and palm oil fatty acid diethanol amide, which is a coconut oil washing in ethanol, is slowly introduced into the mixer (see step S20). In this case, the non-ionic surfactant is composed of COCAMIDE DIETHANOL AMINE (CDE), it is preferable to constitute a ratio of about 2% by weight compared to the total cleaning agent, the cleaning liquid composition added to the mixer.

After stirring the non-ionic surfactant mixed by the above procedure for 10 minutes to rot well with the water and ethanol, the antistatic agent consisting of an anionic activator that coats the surface and prevents static electricity, so a lot of bubbles are generated Be careful not to add it slowly to the mixer. At this time, the antistatic agent was added to the mixer by weighing DIMETHYL AMINOETHYL META ACRYLATE (DMAA) in a weight ratio of about 20% and stirred for 5 minutes as in the procedure of the surfactant (see step S30).

After the above process, the washing agent, which serves as a secondary agent during washing, is composed of the total washing agent and the weight ratio of the washing liquid to about 5%, and added to the mixer and stirred for 5 minutes. (See step S40.) It is preferably composed of ETHER (DPM).

If the material introduced by the stirring procedure is well decayed, gold nano (Au Nano) having excellent antibacterial and deodorizing ingredients is weighed and introduced into the mixer, and the stirring procedure is performed for 10 minutes.

At this time, the amount of gold nano (Au Nano) can be variably configured to a weight ratio of about 3% to 10% in consideration of the ratio of water, ethanol, nonionic surfactant, antistatic agent and tax information to be added to the mixer. In the production of 100kg gold nano antimicrobial cleaner, it is desirable to make 10ppm per lkg of gold nano solution.

After the above process, the deodorant (Odor neutralizer) composed of SOYETHYL MORPHOLINIUM ETHOSULFATE to neutralize the odor to about 3% by weight of the total composition was added to the mixer and stirred for 20 minutes to confirm that the fragrance was well decomposed with the detergent. Reference)

After the mixing of each raw material in the above process, a sample of the cleaning agent, the cleaning solution is taken, the pH concentration is measured and neutralized so that the pH concentration is 7.0 ± 0.5 and stirred for 20 minutes (see step S70).

If the pH concentration is normal by sampling, the sample is taken for each lot and the filling procedure is performed (see step S80).

The test results of the antimicrobial activity of the detergent by the test method of FIG. 2 attached to the gold nano antibacterial detergent prepared by the above procedure are shown as follows.
