At present, in public places, particularly in hospital environments, more than 200 kinds of bacteria and viruses such as traditional influenza germs, avian influenza, pneumococci and the like are dispersed in the air, and the health of human beings is threatened all the time. Along with the rise of air temperature and the deterioration of environment, the traditional virus generates drug resistance, the novel bacteria and viruses are endless, the bacteria and the viruses are spread along with the air, the speed is high, the influence is wide, large-scale epidemic situation is easily caused, and immeasurable potential influence is brought to the life and property and social order of people.
The existing quaternary ammonium salt disinfection material is applied in large scale due to the characteristics of lasting sterilization and disinfection capability, spectrum, low toxicity and the like on the surface of an object, but the capability of the atomized quaternary ammonium salt for killing viruses and bacteria in the air is extremely limited. And the chlorine-containing disinfection material, ozone or hydrogen peroxide and the like have good killing effect on bacteria and viruses in the air. However, chlorine-containing disinfection materials and ozone have pungent odor, and are emitted in the air, so that the chlorine-containing disinfection materials and the ozone have potential harm to human bodies. The instability and poor disinfection of conventional low concentration hydrogen peroxide solutions also limit their utility. There is a high demand for a new type of sterilization material to cope with the current severe environment.
The problem can be solved by the appearance of the nano-silver/hydrogen peroxide/salicylic acid composite disinfection material, and the composite material has the following functions and characteristics: (1) the nano silver/hydrogen peroxide/salicylic acid composite disinfection material is odorless, colorless and non-foaming, and belongs to a non-toxic grade under the condition that the use concentration is 10 times that recommended. (2) The nano-silver particle size in the prepared nano-silver/hydrogen peroxide/salicylic acid composite disinfection material is less than 5nm, and the nano-silver/hydrogen peroxide/salicylic acid composite disinfection material has very high activity and can quickly sterilize and inhibit bacteria; (3) the low-concentration hydrogen peroxide solution has obviously enhanced oxidizing property and obviously improved sterilizing and disinfecting capability under the acidic condition. The salicylic acid has good sterilization and bacteriostasis effects, the hydrogen peroxide solution can be adjusted to be acidic, and after the salicylic acid is added into the hydrogen peroxide solution, the nano-silver/hydrogen peroxide/salicylic acid composite disinfection material has the advantage that the sterilization and disinfection capacity is improved in geometric grade by virtue of the coupling effect. (4) The low concentration hydrogen peroxide solution is easily decomposed, resulting in short life and greatly reduced performance. However, the nano silver solution is added into hydrogen peroxide and exists as a stabilizing agent, the stabilizing agent can prevent the slow decomposition of the hydrogen peroxide, the composite sterilizing material can be stored for at least 28 months, and the sterilization is carried outThe material can maintain the disinfection effect for a long time and high efficiency, has large application elasticity, is hardly influenced by temperature and light, and even enhances the disinfection capability at high temperature. (5) Two basic components (H) of the composite sterilizing material202And nano silver) improves respective advantages through cooperation, and the sterilization and disinfection effects are more rapid and concentrated. The bacteria and the viruses have a biological film protective layer, the most important means for killing the bacteria and the viruses is that the biological film can be thoroughly destroyed, the nano-silver can destroy cell membranes of the bacteria or the viruses, and then the hydrogen peroxide instantly oxidizes middle proteins of the bacteria or the viruses, so that the bacteria and the viruses can be efficiently and quickly killed. (6) The composite sterilizing material has powerful broad-spectrum sterilization, can kill more than 200 bacteria and viruses of traditional influenza germs, avian influenza, pneumococcus and the like, and can also kill super bacteria and viruses of poliomyelitis, Norwalk and the like which are difficult to kill in hospitals. (7) The nano silver/hydrogen peroxide/salicylic acid composite disinfection material is used for sterilizing through oxidation, so that the problem of drug resistance of viruses, bacteria, fungi, microorganisms and other unknown diseases is solved, and the nano silver/hydrogen peroxide/salicylic acid composite disinfection material can be used for a long time. (8) The nano silver particles in the nano silver/hydrogen peroxide/salicylic acid composite disinfection material have good catalytic oxidation performance under the action of hydrogen peroxide, can quickly remove formaldehyde, peculiar smell and other problems in the space, and greatly expands the application range of the invention.
