Description

Technical Field

[0001] The invention relates to the technical field of coating antibacterial agents, and in particular to an antibacterial agent sprayed on a surface of an object. Background Art

[0002] In modern society, antimicrobial treatment of surfaces has become increasingly important, especially in the fields of medicine, food processing and public health. Traditional antimicrobial methods include the use of chemical disinfectants, heat treatment and radiation disinfection. Although these methods are effective to a certain extent, they also have obvious shortcomings. For example, chemical disinfectants may be harmful to the human body and the environment, and long-term use may also cause microorganisms to develop drug resistance. Heat treatment and radiation disinfection require special equipment and operating conditions and are not suitable for all occasions.

[0003] The shortcomings of existing surface antimicrobial technologies are mainly reflected in the following aspects: first, the antimicrobial effects of many antimicrobial agents are limited and are not effective against all types of microorganisms; second, some antimicrobial agents may have adverse effects on the human body or the environment, especially when used for a long time or in large quantities; third, traditional antimicrobial treatment methods are complicated to operate and are not suitable for rapid and large-scale applications; finally, some antimicrobial treatment methods are expensive, which limits their application in a wide range of fields.

[0004] Therefore, it is urgent to develop a new type of antibacterial agent for surface spraying. This agent should have a broad-spectrum antibacterial effect and can effectively inhibit or kill various microorganisms. At the same time, it should be safe and harmless, friendly to the human body and the environment. In addition, the application method of this antibacterial agent should be simple and fast, and it is convenient to quickly apply it on the surfaces of various objects. Finally, in order to promote its wide application, the cost of this agent should be controlled within a reasonable range. For this reason, the present invention proposes an antibacterial agent for surface spraying to solve the above problems. Summary of the invention

[0005] In order to overcome the defects of the prior art, the purpose of the present invention is to provide an antibacterial agent for spraying on the surface of an object to solve the problems raised in the above background technology.

[0006] To achieve the above object, the technical solution of the present invention is implemented as follows: an antibacterial agent for surface spraying comprises the following components (by weight percentage): Nano silver or nano copper materials: 10-20%; Yeast extract: 5-15%; Silver ions and organic antimicrobial agents: 10-25%; Chlorophyll: 5-15%; Polytetrafluoroethylene: 5-10%; Polylactic acid PLA: 10-20%; Enzyme-based antimicrobial agents: 5-10%; Stabilizer: 1-5%; Preservatives: 0-1%; Water or other solvents: balance to 100%.

[0007] Preferably, the particle size of the nano-silver or nano-copper material is in the range of 1 to 100 nanometers.

[0008] Preferably, the yeast extract is selected from yeast cell wall polysaccharides, yeast proteins and combinations thereof.

[0009] Preferably, the silver ions and the organic antibacterial agent are selected from phenols, alcohols, ketones, ethers, acids, amino acids and combinations thereof.

[0010] Preferably, the chlorophyll is selected from natural chlorophyll, synthetic chlorophyll and a combination thereof.

[0011] Preferably, the enzyme-based antimicrobial agent is selected from protease, lipase, cellulase, amylase and combinations thereof.

[0012] Preferably, the stabilizer is selected from boric acid, borax, sodium borate, potassium borate and combinations thereof.

[0013] The beneficial effects of the present invention are embodied in: Strong antibacterial ability: The combination of nanosilver or nanocopper materials and silver ions with organic antimicrobial agents provides the agent with a strong antimicrobial effect. Nanosilver and silver ions are both widely recognized antimicrobial ingredients, and the addition of organic antimicrobial agents further enhances this effect. This allows the agent to effectively inhibit the growth of bacteria and microorganisms on a variety of surfaces.

[0014] Application of natural ingredients: The use of yeast extract and chlorophyll not only enhances the antibacterial effect of the agent, but also adds the advantages of natural ingredients to the product. Yeast extract has good skin compatibility, while chlorophyll provides the agent with natural pigments and additional antioxidant properties.

[0015] Stability and durability: The addition of polytetrafluoroethylene and polylactic acid PLA increases the stability and adhesion of the antibacterial agent, allowing the agent to adhere to the surface of the object more permanently after spraying, providing long-term antibacterial protection.

[0016] Multifunctional enzyme-based antimicrobial effect: The use of enzyme-based antimicrobial agents provides a multifunctional antimicrobial approach. These enzymes, such as proteases and lipases, can break down key components of bacterial cell walls, thereby effectively killing bacteria.

[0017] Stability of the formula: The use of stabilizers ensures the stability of the pharmaceutical ingredients during storage and use, reducing the decline in efficacy due to deterioration or separation of the ingredients.

[0018] Environmental protection and safety: The use of natural ingredients and environmentally friendly materials in the agent reduces potential harm to the environment and human body, making the agent more suitable for wide application in various environments, such as food processing, medical equipment, daily necessities and other fields.

[0019] In summary, this surface-sprayed antibacterial agent not only has a strong antibacterial ability, but also has good environmental protection, safety, stability and durability, making it a versatile, efficient and environmentally friendly antibacterial option. Implementation
