A kind of active silicon antibacterial liquid modified by traditional Chinese medicine oil, its preparation method, and the preparation method of antibacterial coating

Abstract

The invention belongs to the field of antibacterial materials and discloses an active silicon antibacterial liquid modified by traditional Chinese medicine oil. It is composed of quaternary ammonium salt, 1-20 parts of organic acid, 1-10 parts of deionized water, 0.1-10 parts of catalyst and 40-80 parts of organic solvent. The invention also discloses a preparation method of the active silicon antibacterial liquid and a preparation method of the antibacterial coating. The present invention selects traditional Chinese medicine oil with specific components (both containing active hydroxyl components), and combines them with aminated organic silicon quaternary ammonium salts to play a synergistic and superimposed killing effect on bacteria. The bactericide is long-lasting, safe and non-toxic, easy to use and simple in preparation process, and has a good market application prospect.

Description

technical field [0001] The invention belongs to the field of antibacterial materials, in particular to an active silicon antibacterial liquid modified by traditional Chinese medicine oil, a preparation method thereof, and a preparation method of an antibacterial coating. Background technique [0002] With the rapid development of social economy and the continuous improvement of living standards, smart phones have become one of the indispensable daily necessities in people's lives, and are also profoundly affecting and changing human lifestyles. Little do they know that the touch screen of a mobile phone has become a base for a large number of bacteria to multiply. According to a survey, there are 120,000 bacteria per square centimeter on the screen of a mobile phone. Based on this, it is estimated that there are at least millions of bacteria in the entire mobile phone, and some of them directly endanger people. of good health. For this reason, the application of durable ant...

Problems solved by technology

For example, the silver ion sterilization process is that the silver ion first breaks the bacterial cell wall, and then makes its protein flow out. At the same time, the silver ion Ag+ will chemically react with the sulfhydryl group of the protease to form silver sulfide. This chemical reaction is irreversible. Prolonged, silver ions are continuously consumed, and will fail over time. Therefore, the timeliness of silver ion antibacterial products is usually less than 1 year, which cannot reach the 2 to 5 years advertised by many merchants. This is also why silver antibacterial products are difficult to be used. One of the main reasons for the wide recognition in the market

In addition, silver ions are easily oxidized by air to make the coating yellow and black, so most antibacterial products doped with silver ions have the problem of color change during use.

Finally, silver ions and copper ions are heavy metal ions, and ingesting a certain amount will cause great harm to the human body. Therefore, such products are only used in the industrial field, and are generally not used as daily disinfectants at home.

[0007] 2. Chitin antibacterial agent: Chitin is a natural antibacterial product. Although it has a certain antibacterial ability, it is far weaker than silver ions. Therefore, a large amount of chitin must be used to have better antibacterial function, resulting in higher costs. As a result, such antibacterial products are rare in the market

[0010] At present, the active silicon antibacterial liquid containing traditional Chinese medicine oil and capable of lasting sterilization has not been reported yet.
