Description
Technical Field
The invention relates to the technical field of air purification and disinfection, in particular to an anion antibacterial agent and a preparation method thereof.
Background
Indoor air is closely related to human health. For example, the air may be polluted due to decoration, addition of new furniture, or poor ventilation, so that the air contains toxic substances, which are harmful to our health. For example, in places with large population flow, dense population and relatively high infection source density, the air quality is very high, and indoor air purification and disinfection are needed. The air cleaning and sterilizing methods are classified into a static sterilizing method and a dynamic sterilizing method. The static disinfection method is that in a closed indoor space, an air purification disinfectant with a certain concentration is sprayed by a spraying method, disinfection is carried out for 2-4 hours, the number of bacterial colonies before and after indoor disinfection is measured, and the average sterilization rate is calculated; the dynamic disinfection method is to place the air purification disinfectant in a closed indoor space without influencing indoor work, detect the colony number in the space where the air purification disinfectant is/is not placed on site, and calculate the average sterilization rate. At present, although the air purification disinfectors on the market generally have the sterilization effect, the air purification disinfectors can only emit short-term fragrance and can only be called air aromatic at best, so that the air disinfectors for effectively sterilizing on the premise of not influencing the health of human bodies are difficult; in addition, when the static disinfection method and the dynamic disinfection method are applied to air disinfectants, how to maximize the disinfection effect of the air disinfectants also becomes a difficult problem in the industry.

Example 2:
in this example, an anion release amount test was performed on the anion antibacterial agent provided above.
Experimental equipment: air ion counter
The experimental principle is as follows: an air ion counter is an instrument for measuring the total concentration of negative ions, and adopts a capacitance type air ion collector to collect the charges carried by air ions, and measures the current formed by the discharge of the charges through a micro-current meter. The structure of the ion collector mainly comprises three parts, namely an ion collector, an air extractor and a micro-current meter, when air ions enter the collector along with the transportation of sampling airflow, the ions are respectively deflected to the collecting plate or the polarizing plate according to different polarities under the action of a polarizing electric field between the collecting plate and the polarizing plate, and charges carried by the ions are respectively transferred to the collecting plate and the polarizing plate. The charge on the plates creates a current through the micro-current meter. Corresponding negative ion concentration calculation
The formula is as follows:
N＝I/(q·v·A)
wherein the content of the first and second substances,
n is the number of ions per unit volume of air (ions/cm 3);
i is the micro-current meter reading (A);
q is the basic charge capacity (1.6x 10)-19C)；
v is the sampling air flow rate (cm)3/s)；
A is the effective cross-sectional area (cm) of the collector2)。
The experimental process comprises the following steps: respectively at a closed 10m3、50m3、100m3In the test, 100g of the anion antibacterial agent is uniformly sprayed, and after 5, 15 and 30 minutes, the corresponding anion concentration is tested by an air ion counter, as shown in table 1:
TABLE 1 anion concentration test results
As can be seen from table 1, the use of the negative ion antimicrobial agent of the present invention can generate a large amount of negative ions in the air, and the concentration of the negative ions can be maintained at a high level as time passes.
Example 3:
in this example, a sterilization experiment was performed on the negative ion antibacterial agent provided above.
Experimental equipment: synthetic air (79% N2, 21% O2) was purchased from Hepu Limited. Tryptone and yeast powder were purchased from Oxoid corporation. Sodium chloride was purchased from Beijing Chemicals, Inc. Agar was purchased from the ancient China Changsheng biotechnology limited. Phosphate buffered saline (PBS, 0.01M, p H: 7.4) was purchased from Sigma. Gram stain kits were purchased from Solarbio ltd.
The experimental process comprises the following steps:
1) preparing a culture medium:
the liquid Luria-Bertani (LB) culture medium comprises 10g/L tryptone, 5g/L yeast powder and 10g/L sodium chloride. 20g/L agar is added on the solid LB culture medium components. Liquid media was used for bacterial proliferation, while solid media was used to examine the interaction between staphylococcus aureus and negative ions. Tinfoil paper is first placed on the bottom and walls of the culture dish. Then solid LB medium was added on tin foil. Subsequently, the culture medium was perforated with holes (6 mm in diameter and 4 mm in depth) which penetrated the bottom of the tin foil.
2) Bacterial culture
The material used for the cylindrical reaction chamber was glass (diameter: 9cm, height: 20 cm). The surfaces of the glass chamber were sterilized with alcohol prior to testing. The negative ions generated at the top move downward to contact and act on the bacteria at the bottom. The top two holes were connected to the outside and the ground was connected to the tinfoil paper and the whole test was performed at 37 ℃. After the reaction was completed, the bacteria on the surface were collected and suspended in sterile distilled water, and then the number of bacteria in the suspension was counted to obtain the concentration. The sterilization efficiency calculation formula is as follows:
according to experimental results, the sterilization efficiency of the negative ion antibacterial agent reaches more than 90%.
Example 4:
in this example, to verify the specific effects of the components, the components were divided into four components, namely, an oil-in-water emulsion consisting of vegetable oil and deionized water, a mixed powder consisting of phlogopite powder and albite powder, nano silver ions, and potassium-40 with a trace amount of radioactivity, and the effects of the four components were verified respectively,
the specific grouping situation is shown in table two:
TABLE TWO-PACKET CONDITIONS
Then five groups of negative ion antibacterial agents are used for respectively sealing five 100m3In the space, evenly spray 100g anion antibacterial agent, after 5, 15, 30 minutes, test corresponding anion concentration through the air ion counter to and the efficiency of disinfecting, specifically as shown in table 3, table 4:

| Group of | First group | Second group | Third group | Fourth group | Fifth group |
| Sterilization efficiency (%) | 75 | 50 | 75 | — | 98 |
