Background
At present, the common use of domestic public places and personal hygiene protective articles is as follows: organic and inorganic disinfectants or natural antibacterial products kill pathogenic bacteria. However, these disinfection products (such as chlorinated ethanol disinfectant) have a disadvantage that after the instantaneous second sterilization, the disinfectant volatilizes in a short time, and bacteria propagated in the air subsequently grow again on the surface of the object, so that they do not have the function of continuous bacteriostasis.
In order to solve the technical problems, the technical personnel in the field design and produce the composite nano-ion antibacterial liquid which has the characteristics of safety, long acting and no pollution, and is more convenient and efficient in acting scenes and use. The most widely applied elements in the composite nano-ion antibacterial liquid are silver (Ag), copper (Cu), zinc (Zn) and the like. The inorganic antibacterial agent represented by nano silver and nano copper has the characteristics of long duration, broad-spectrum sterilization, strong sterilization effect and the like. However, the production cost of nano silver products and nano copper products is high, and the nano silver products and the nano copper products are easy to oxidize and discolor; the silver does not participate in metabolism in a human body, the health of the human body can be influenced after long-time use, the nano zinc does not have the use problem of the nano silver and the nano copper, and has the same lasting sterilization and bacteriostasis effects as the nano silver and the nano copper antibacterial materials, but the second sterilization effect of the nano zinc is not as good as that of the nano silver, and the experimental result shows that more than 90 percent of bacteria are killed, the nano zinc needs at least 5 hours, and the nano silver only takes 600 seconds; therefore, how to repair the short plate of nano zinc to make it a novel antibacterial product becomes an important technical problem for improving the antibacterial effect of the composite nano ionic antibacterial liquid.

Detailed Description
Example 1
The application is characterized in that a micro-nano zinc ion, a micro-nano silver ion and a micro-nano copper ion are added into a nano ion antibacterial liquid to compound silver ions, copper ions and zinc ions in the nano ion antibacterial liquid, the micro-nano zinc ion is formed after mixing the nano zinc ion and the micron zinc ion, the micro-nano silver ion is formed after mixing the nano silver ion and the micron silver particle, the micro-nano copper ion is formed after mixing the nano copper ion and the micron copper ion, the killing rate of the composite nano ion bacteriostatic agent adopting the micro-nano zinc ion, the micro-nano silver ion and the micro-nano copper ion to escherichia coli, staphylococcus aureus and candida albicans reaches more than 99%, and the technical effect of continuous sterilization is achieved in subsequent 36 hours, and the sterilization rate reaches 99%. The nano ion bacteriostatic agent compounded by micro-nano zinc ions, micro-nano silver ions and micro-nano copper ions still has a bactericidal effect for five years, and the bactericidal effect is obtained by performing a simulated accelerated aging test by an ASTM F1980 method.
The creation point of the application is that the percentage of micro-nano zinc ions, micro-nano silver ions and micro-nano copper ions added into the nano ion antibacterial solution is as follows:
0.2 to 0.7 percent of micro-nano zinc ions
Micro-nano silver ion 0.1-0.3%
0.1 to 0.3 percent of micro-nano copper ions.
The creation point of the application is that the percentage of micro-nano zinc ions, micro-nano silver ions and micro-nano copper ions added into the nano ion antibacterial solution is as follows:
micro-nano zinc ion 0.45%
Micro-nano silver ion 0.2%
0.2 percent of micro-nano copper ions.
The key of the technical scheme is effective compatibility of the characteristics of various ions. Through TEM observation of a transmission electron microscope, part of the micro-nano zinc ions belong to the nano level, and the other part of the micro-nano zinc ions belong to the micron level, so that different bactericidal effects are presented; the micro-nano zinc has stronger catalytic capability, and forms freely moving negatively charged electrons and positively charged holes. "as if each were sitting in aligned seats in a movie theater. If a person is regarded as an electron, the person will have more empty positions, i.e., holes, as long as the person stands up and walks, and becomes a 'free electron'. The oxygen, hydroxyl, water and the like adsorbed on the surface of the material can sit on the empty positions to generate hydroxyl radicals and active oxygen ions with reduction action, and the oxygen in the air and the water is excited to be changed into active oxygen ROS. Active oxygen has extremely strong oxidizing activity, and can destroy the proliferation capacity of bacterial cells, thereby inhibiting or killing bacteria. The specific surface effect of the micro-nano zinc ions is also easy to generate affinity with contacted bacteria.
In addition, zinc ions have oxidation-reduction property, and can pierce the membrane protein structure of bacteria to lose activity, thereby achieving the purpose of sterilization. After the bacteria are killed, zinc ions with strong vitality can be dissociated from the dissolved bacteria and then contact with other bacteria to complete a new sterilization task, so that the strong sterilization activity is shown. According to detection, the micro-nano zinc compound has good bactericidal and bacteriostatic effects on known common bacteria and is lasting and effective. Experiments prove that the compound nano-ion bacteriostatic agent has a killing rate of more than 99% on various pathogenic bacteria such as escherichia coli, staphylococcus aureus, candida albicans and the like. The sterilization lasts for 8 hours and 36 hours, and 99 percent of the sterilization still remains. Meanwhile, the micro-nano zinc compound is subjected to a simulated accelerated aging test by using an ASTM F1980 method, and the sterilizing effect is still achieved after 5 years.
