Description

Technical Field

[0001] The invention relates to the technical field of air sterilization, in particular to a paste-like antibacterial composition. Background Art

[0002] At present, people have an increasing demand for air conditioners. Currently, household air conditioners basically have no antibacterial modules and antibacterial functions. Many households are often infected by fungi, such as tinea corporis. Car air conditioners are only filters. Car air conditioners intercept some harmful substances outside the car through filtration, such as PM2.5, but fungi can still enter the car through the car air conditioner and pollute the air. Currently, replacing the air conditioner filter in the car can inhibit some fungi, but it cannot achieve good antibacterial effect. When the filter is reinstalled, fungi will breed again. Therefore, products with antibacterial functions are needed to inhibit the growth of bacteria in the air in a closed space to maintain air hygiene. However, common antibacterial products on the market, such as alcohol, are all liquids, and their application occasions are limited. For example, the shaking caused by driving on the vehicle may cause the liquid to spill. Summary of the invention

[0003] In view of the above-mentioned defects of the prior art, the task of the present invention is to provide a paste-like antibacterial composition, the purpose of which is to solve the problem that liquid antibacterial agents are easy to spill and general solid antibacterial products need to be in direct contact with the disinfected products and cannot achieve antibacterial effects on the air.

[0004] The technical scheme of the present invention is as follows: a paste antibacterial composition comprises the following components by weight: 50-65 parts of allyl isothiocyanate, 10-15 parts of paraffin, 10-20 parts of moisturizing antifreeze agent and 10-20 parts of rosin-based ester complex.

[0005] Furthermore, the moisturizing antifreeze agent is at least one of caprylic / capric triglyceride, glycerol, glycol, and polyethylene glycol.

[0006] Furthermore, the moisturizing antifreeze agent is caprylic / capric triglyceride.

[0007] Furthermore, the diol is at least one of propylene glycol and butylene glycol.

[0008] Furthermore, the moisturizing antifreeze agent is a mixture of at least one of glycerol, glycol, polyethylene glycol and caprylic / capric triglyceride.

[0009] Furthermore, the diol is at least one of propylene glycol and butylene glycol.

[0010] Furthermore, the rosin-based ester compound is at least one of hydrogenated rosin pentaerythritol ester, rosin glycerol ester, and maleic anhydride-modified rosin glycerol ester.

[0011] The advantages of the present invention compared with the prior art are:

[0012] The present invention utilizes the antibacterial effect of allyl isothiocyanate, and the paste antibacterial composition prepared will not spill, and can inhibit the content of bacteria in the air through volatility, has a broad-spectrum antibacterial effect, has no toxic side effects on the human body, is environmentally friendly, does not need to directly contact with objects in the space, and can achieve the antibacterial effect, and is suitable for air-conditioning systems such as automobiles. The use of a moisturizing antifreeze agent can improve the stability of the paste antibacterial composition and has an antifreeze effect, ensuring the volatilization effect at low temperatures. Further, using caprylic acid / capric acid triglyceride as a moisturizing antifreeze agent can also solve the problem of reducing the volatilization of a part of volatiles due to the emulsification process when using glycerol, thereby ensuring the volatilization antibacterial effect. The rosin-based lipid compound can stabilize the antibacterial composition, so that it can be volatilized in a small amount and uniformly for a long time, thereby extending the effective use time.

[0019] The present invention will be further described below in conjunction with the embodiments, but are not intended to limit the present invention.

[0020] The CAS numbers of the raw materials involved in the examples are: hydrogenated rosin pentaerythritol ester (6683-19-8), paraffin (8002-74-2), caprylic / capric triglyceride (65381-09-1), and glycerol (56-81-5). The preparation process is to uniformly mix all the raw materials in the composition.

[0021] Example 1 A paste-like antibacterial composition, comprising 50 parts of allyl isothiocyanate, 10 parts of paraffin, 10 parts of glycerol and 10 parts of hydrogenated rosin pentaerythritol ester.

[0022] Example 2 A paste-like antibacterial composition, composed of 50 parts of allyl isothiocyanate, 10 parts of paraffin, 10 parts of caprylic / capric triglyceride and 10 parts of hydrogenated rosin pentaerythritol ester.

[0023] Example 3 A paste-like antibacterial composition, composed of 55 parts of allyl isothiocyanate, 12 parts of paraffin, 15 parts of caprylic / capric triglyceride and 15 parts of hydrogenated rosin pentaerythritol ester.

[0024] Example 4 A paste-like antibacterial composition, composed of 65 parts of allyl isothiocyanate, 15 parts of paraffin, 20 parts of caprylic / capric triglyceride and 20 parts of hydrogenated rosin pentaerythritol ester.

[0025] According to the 2002 edition of the "Technical Specifications for Disinfection", 2.1.3, the antibacterial performance of each embodiment was tested in the following environment: temperature 23.9°C, relative humidity 64%, and the testing method was to test the antibacterial performance of each embodiment at 3m 3 In the aerosol chamber, the fan was used to stir while spraying. After spraying, the fan continued to stir for 5 minutes, and then it was left to stand for 5 minutes. The number of positive control bacteria in the air of the aerosol chamber reached 5.0×10 4 cfu / m 3 ~5.0×10 6 cfu / m 3 . Use a liquid impact microbial aerosol sampler to sample the aerosol chambers of the test group and the control group before disinfection. Sampling is performed at a flow rate of 11L / min. The volume of the sampling liquid is 20mL, and the sampling time for both the test group and the control group is 2min. Unscrew the three sachets containing the paste-like antibacterial composition, turn on the prototype, and act for 5min, 15min, 30min, 60min, 90min, and 120min, respectively, and then sample the aerosol chamber after disinfection at the same flow rate. The sampling time for both the test group and the blank control group is 2min. Place the collected plates in a 37.0℃ incubator for 48h and observe the results. The detailed results of Example 3 and the blank control group are as follows

[0026]

[0027] The average bactericidal rate of the antibacterial paste composition of Example 1 after 120 minutes is 90.22%, the average bactericidal rate of the antibacterial paste composition of Example 2 after 120 minutes is 92.53%, and the average bactericidal rate of the antibacterial paste composition of Example 4 after 120 minutes is 95.34%. It can be seen that due to the glycerol emulsification coating, the content of volatile antibacterial components is low, and the bactericidal rate of the antibacterial paste composition of Example 1 is lower than the bactericidal rate of the antibacterial paste composition of Examples 2-4 at 120 minutes.

[0028] The volatility test of the paste antibacterial composition of Example 1 and Example 3 was carried out at 25±1°C, 50±1°C and -40±1°C respectively. The experimental results are as follows: Figures 1 to 6 As shown, the ordinate represents the average daily volatility, the average daily volatility = (initial weight - final weight) / (initial weight * interval days), and the abscissa represents the number of days. The maximum average daily volatility of Example 1 at 25 ± 1 ° C and -40 ± 1 ° C did not exceed 0.001, and the maximum average daily volatility at 50 ± 1 ° C was about 0.0015. The maximum average daily volatility of Example 3 at 25 ± 1 ° C was about 0.017, and the minimum average daily volatility was about 0.009, the maximum average daily volatility at 50 ± 1 ° C was about 0.024, and the minimum average daily volatility was about 0.014, and the maximum average daily volatility at -40 ± 1 ° C was about 0.005, and the minimum average daily volatility was about 0.0018. It can be seen from the experiment that the paste antibacterial composition using caprylic / capric triglyceride as a moisturizing antifreeze has better volatility under multiple temperature conditions than using glycerol as a moisturizing antifreeze, and can play a better bactericidal role.
