Background
The chlorine dioxide disinfectant is an internationally recognized high-efficiency disinfectant, can kill most pathogenic microorganisms including bacteria propagules, bacterial spores, fungi, mycobacteria, viruses and the like, does not generate drug resistance, has strong adsorption penetrating capacity on microbial cell walls, can effectively oxidize enzymes containing sulfydryl in cells, and can quickly inhibit the synthesis of microbial proteins to destroy microorganisms, and the traditional application of the chlorine dioxide disinfectant has two types, namely a binary package: one is stable chlorine dioxide solution, the stable chlorine dioxide solution is colorless, tasteless, non-corrosive, non-flammable, non-volatile, non-decomposition, stable in property, convenient for storage and transportation, and ineffective when used alone, and an activating agent is required to be added to release chlorine dioxide; the other is solid chlorine dioxide, wherein one bag is sodium chlorite, the other bag is an activating agent, and the chlorine dioxide is quickly generated after the chlorine dioxide is respectively dissolved in water and mixed when used;
chlorine dioxide is a safe, high-efficient and broad-spectrum disinfectant, and has been widely used in environmental disinfection, because chlorine dioxide is difficult to compress and store, and has active property and difficult to exist stably, the prior disinfectant generally mixes the precursors of chlorine dioxide stably, and water is added to react and activate chlorine dioxide when in use, for example, the publication No. CN108849973A discloses a stable chlorine dioxide disinfectant powder and a preparation process thereof, and the publication No. CN105906005A discloses a compound water purification disinfection effervescent tablet and a technical scheme of a preparation method thereof, or the two are required to be mixed and activated when in use, for example, the publication No. CN102626104A, a stable chlorine dioxide disinfectant and a preparation method thereof, CN102113517A an air purifying agent, and CN102390813A, a stable chlorine dioxide preparation method, are inconvenient to use;
the existing unitary chlorine dioxide disinfectant, for example, patent proposal with publication number CN106879626B, discloses a chlorine dioxide disinfectant and a preparation method thereof, when used for disinfecting the object surface, although the disinfectant can kill pathogenic microorganisms on the surface immediately, because the nature of chlorine dioxide is active, the disinfectant can be decomposed rapidly under the conditions of illumination and the like, and is difficult to stay on the object surface, and the long disinfection effect can not be maintained; patent scheme with publication number CN107568208A discloses a disinfection technology combining chlorine dioxide and zinc, but the content of chlorine dioxide released by the technology for air disinfection is too low, and there is some residue on the surface when disinfection is performed on a gel-state object surface, and meanwhile, from the realization process of the technology, the product starts to react to release chlorine dioxide after being prepared, and cannot be stably stored; the patent scheme with the publication number of CN108967450A discloses a disinfectant combining chlorine dioxide and nano zinc, but the technology is only used in the field of water purification, the concentration of zinc contained in the disinfectant is too high, and the disinfectant is precipitated and layered in water on the premise of not dispersing and is not suitable for environmental disinfection;
at present, the lasting antibacterial property of inorganic metal is taken into consideration, wherein the elements which are most widely applied comprise silver (Ag), copper (Cu) and zinc (Zn), and 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, and can be widely applied once being on the market, but the nano silver product and the nano copper product have higher production cost and are easy to oxidize and discolor; the nano zinc is equivalent to nano silver and nano copper antibacterial materials in the aspect of lasting sterilization and bacteriostasis effects, but the nano zinc has weak sterilization effect, and the experimental result shows that more than 90% of bacteria are killed, the nano zinc needs at least 5 hours, and the nano silver only takes 600 seconds; therefore, the chlorine dioxide nano zinc disinfection bacteriostat liquid is provided, and a high-efficiency bacteriostat product is developed by combining the strong bactericidal capacity of chlorine dioxide and the bacteriostasis capacity of nano zinc.

the method comprises the following steps: taking pure water as a substrate, sequentially adding the nano zinc dispersion liquid and the regulator into the pure water, and mixing for 10-15min to obtain an absorption liquid;
step two: according to the first step, chlorine dioxide gas is absorbed by absorption liquid to obtain chlorine dioxide nano zinc disinfection liquid;
step three: weighing and packaging to obtain the required chlorine dioxide nano-zinc disinfection bacteriostat.
3. The method for preparing nano zinc chloride disinfection and bacteriostasis solution as claimed in claim 2, wherein said chlorine dioxide is prepared by reacting sodium chlorite with hydrochloric acid or sulfuric acid, preferably hydrochloric acid, wherein the concentration of the reaction solution of sodium chlorite and hydrochloric acid is 5% -30%, the reaction is equal volume, and negative pressure absorption is adopted to facilitate the absorption solution, and the reaction temperature is 20 ℃.
4. The method for preparing nano zinc chloride disinfection and bacteriostasis liquid according to claim 3, wherein in the second step, the nano zinc chloride disinfection liquid is prepared by introducing chlorine dioxide gas into absorption liquid at a flow rate of 0.2-2.0 mlL/min at an ambient temperature of 10-20 ℃ in a dark place for absorption, and the concentration of chlorine dioxide is 50-500 mg/L.
5. The method for preparing nano zinc chloride disinfectant and bacteriostatic agent according to claim 4, wherein in the first step, the nano zinc dispersion is prepared by adding nano zinc into a dispersant with a mass fraction of 1% -10% under ultrasonic conditions and performing ultrasonic dispersion for 5-15 min, wherein the dispersant contains one or two of sodium dodecyl benzene sulfonate or sodium dodecyl sulfate.
6. The method for preparing nano zinc chloride disinfectant and bacteriostatic agent according to claim 5, wherein the nano zinc is prepared by mixing zinc oxide, zinc ferrite and zinc undecylenate with particle size of 10-990 nm, wherein the mass fraction is 0.1-5% calculated by the content of zinc.
7. The method for preparing nano zinc disinfection bacteriostat of chlorine dioxide as claimed in claim 6, wherein in the first step, the regulator comprises EDTA-Na, benzoic acid or phthalic acid, and the preparation method of the regulator is as follows:
firstly, adding 5-20 g/L of EDTA-2Na into a solution to which nano zinc is added;
adjusting the solution to 4-7 by using benzoic acid or phthalic acid;
thirdly, the needed regulator is prepared.
