As a preferred embodiment, the reducing agent is selected from at least one of hydrazine hydrate, sodium borohydride, glucose, and organic alcohol. Preferably, the reducing agent is selected from at least one of glycerol, lactitol, n-pentanol, n-hexanol, and n-dodecanol. Alcohol with different proportions is compounded to control the reduction speed of silver ions, so that the preparation of nano silver with low particle size and uniform dispersion is facilitated; more preferably, the reducing agent is glycerol, n-pentanol, n-dodecanol; the weight ratio of the glycerol to the n-pentanol to the n-dodecanol is (6-8): 3: 1.
silver salts
The silver salt mainly provides silver ions, and is not particularly limited; in the present application, the silver salt is an aqueous nitrate solution. Wherein the concentration of the silver nitrate is 0.05 mol/L.
Lactam group-containing polymer and/or sodium sulfosuccinate
As a preferred embodiment, the mass ratio of the lactam-group containing polymer to the sodium sulfosuccinate alkyl ester is (3-4): 1.
as a preferred embodiment, the lactam-group containing polymer has a lactam-group dipole moment of 30 to 42; preferably, the lactam group of the lactam group-containing polymer is a butyrolactam group; more preferably, the lactam-group containing polymer further comprises a methylene group in the long chain; further preferably, the environments of both ends of the lactam group-containing polymer are different, one end of the oxygen atom is exposed, and the other end of the N atom is surrounded by a methyl group and a methylene group.
As a preferred embodiment, the lactam group-containing polymer has a viscosity (mPa.s/25 ℃/5% aq) of 1.1 to 2.7 and a number average molecular weight of 10000-40000.
In a preferred embodiment, the alkyl group in the sodium sulfosuccinate is at least one selected from the group consisting of ethyl, propyl, isopropyl, n-butyl, isobutyl, sec-butyl, tert-butyl, n-pentyl, isopentyl, sec-pentyl, tert-pentyl, n-hexyl, and isohexyl.
More preferably, the alkyl group in the sodium sulfosuccinate is n-hexyl.
The preparation method of the sodium alkyl sulfosuccinate with n-hexyl alkyl comprises the following steps: 1) adding 4mol of maleic anhydride, 2mol of 1, 3-propylene glycol and a solid acid catalyst (the solid acid catalyst is 3 wt% of the maleic anhydride) into a reactor, uniformly stirring, heating to 100 +/-2.5 ℃, and reacting for 5-6 hours; 2) adding 5mol of n-hexanol into the step 1), uniformly stirring and heating to 200 +/-2.5 ℃, reacting for 4-5 hours to obtain a mixed solution of a compound 2, and filtering to remove the catalyst; 3) reducing the temperature to 110 +/-2.5 ℃, adding sodium hydroxide in the step 2) to adjust the pH value to 7, then adding 4mol of sodium bisulfite (sodium bisulfite water solution with the mass concentration of 35%) and reacting for 40-60min to obtain the sodium hydrogen sulfite. Wherein the solid acid catalyst is purchased from south university synthetic chemistry, ltd.
The nano silver obtained by the method can be combined with sulfydryl in metabolic enzyme of pathogenic bacteria, so that the metabolic enzyme loses activity; and form a reversible complex after reacting with peptidoglycan of the exposed bacterial cell wall, preventing the bacteria from transporting oxygen and energy into the cell interior; can also combine with the DNA of pathogenic bacteria to cause the structural denaturation of the DNA, and finally inhibit the DNA replication; particularly, the polymer containing lactam group and the sodium sulfosuccinate alkyl ester are added in the preparation process, so that the prepared disinfection sterilizing agent has excellent sterilizing performance; the conjecture is that the long chain of the polymer containing lactam group comprises methylene groups, the two ends of the lactam group are in different environments, so that the polymer is easy to adsorb on the surface of the generated nano-silver to play a role in protection, and after the alkyl ester sodium sulfosuccinate is added, the adsorption rate of the polymer containing lactam group and the newly generated nano-particles is promoted to be greater than the rate of Ag mutual aggregation, so that the obtained nano-silver has strong penetrating power while the surface activity is enhanced.
Hydrogen peroxide
Pure hydrogen peroxide is light blue viscous liquid, can be mixed and dissolved with water in any proportion, and is a strong oxidant; the medical hydrogen peroxide can kill intestinal pathogenic bacteria, pyogenic coccus and pathogenic yeast, and is generally used for disinfecting the surfaces of objects. The hydrogen peroxide has the oxidation effect, but the concentration of the medical hydrogen peroxide is equal to or lower than 3 percent, when the medical hydrogen peroxide is wiped on a wound surface, the wound surface can be burnt, and the surface is oxidized into white and bubbles are generated.
The hydrogen peroxide is a commercial product, and can be enumerated by 27.5% of hydrogen peroxide, 35% of hydrogen peroxide and 50% of hydrogen peroxide, and the hydrogen peroxide is 35% of hydrogen peroxide in mass fraction in the application and purchased from fine chemical engineering in the day of Anhui Ling.

Wherein HLB refers to the hydrophilic-lipophilic balance.
The applicant has found that the addition of a polyethylene glycol and fatty alcohol condensate having a hydroxyl value of 90 to 100mgKOH/g and an HLB value of 13 improves the stability of hydrogen peroxide, which is a relatively unstable substance and causes a reduction in sterilization due to decomposition after being left for a certain period of time; however, after the disinfectant is placed at 50 ℃ for 4 hours, the reduction rate of hydrogen peroxide exceeds 50%, so that the disinfectant is difficult to play a good role in polar environments such as severe heat and the like, and the wide application of the disinfectant is limited; the applicant has surprisingly found that when the reducing agent is glycerol, n-pentanol, n-dodecanol, the disinfectant exhibits a hydrogen peroxide reduction of less than 30% after being left at 50 ℃ for 4 hours. The supposition is that the hydrophilic hydroxyl groups of the glycerol and the n-amyl alcohol are smaller and are reasonably inserted into the overlapped gaps of the n-dodecanol, the polyethylene glycol and the fatty alcohol condensation compound to form a tighter protection structure. And when the weight ratio of the glycerol to the n-amyl alcohol to the n-dodecyl alcohol is (6-8): 3: 1, the sterilization performance of the disinfectant is not affected, and the reduction rate of the hydrogen peroxide is less than 15 percent.
As a preferred embodiment, the disinfectant further comprises 8-12mg of quinoxaline compounds and/or p-hydroxyacetanilide; preferably, the weight ratio of the quinoxaline compound to the p-hydroxyacetanilide is 1: (2-4). Further preferably, the quinoxaline compound is 6, 7-dihydroxy-2-quinoxaline carboxylic acid. The 6, 7-dihydroxy-2-quinoxaline carboxylic acid has CAS number 122234-89-3. The CAS number of the p-hydroxyacetanilide is 103-90-2.
The disinfectant can be applied to the surface of any object (can be diluted by 10-100 times according to actual requirements); including but not limited to human skin, tiles, walls, floors, alloys, bathrooms, glass, tabletops, stovetops, sinks, toilets, clothing, curtains, sheets, bedding, sofas, refrigerators, freezers, washing machines, microwaves, mops, plastics, rubber, etc., and also for air disinfection, e.g. indoor environments subject to pathogens such as bacteria, viruses, etc. on suspended particles; volatile gaseous pollutants such as radon, formaldehyde, benzene series, ammonia and the like after decoration and fitment; inhalable particles such as dust, smoke, pollen, etc.; the peculiar smell of life, such as metabolism in a new city, musty smell, garbage smell and the like; and (3) invasion of outdoor polluted air, such as industrial waste gas, automobile tail gas, soil bag dust and the like.
The disinfectant basically has no corrosion effect on stainless steel and carbon steel, but has slight corrosion effect on copper, aluminum, magnesium and the like, and quinoxaline is added into the disinfectantThe compound and the p-hydroxyacetanilide reduce the corrosion effect of the disinfectant on copper, aluminum and magnesium, particularly the weight ratio of the quinoxaline compound to the p-hydroxyacetanilide is 1 (2-4), a magnesium alloy with the type of AZ31 is soaked in the disinfectant for 4 days, the corrosion inhibition efficiency exceeds 98 percent, the presumption is that the content of Al in the magnesium alloy AZ31 is 2.5-3.5 percent, Zn0.6-1.4 percent and Fe 0.003 percent, the magnesium alloy also contains Ni, Cu, Mn and the like, and belongs to a Mg-Al-Zn ternary system, the p-hydroxyacetanilide, 6, 7-dihydroxy-2-quinoxaline carboxylic acid and other components mutually promote, so that carboxyl and N atoms can be well in a second phase Mg with β in skeleton distribution among the branches and crystal boundaries of α bodies17Al12And the like to form a protective film.
A second aspect of the invention provides a method for preparing the disinfectant, comprising the steps of:
(1) sequentially adding a reducing agent, a lactam group-containing polymer and/or sodium sulfosuccinate alkyl ester into 800mL of water at the rotation speed of 1000-1500r/min, and stirring until the mixture is transparent and clear; heating to 20-30 ℃, adding silver salt, continuing heating and stirring, and reacting for 2-4 hours; (2) and (2) adding a polyethylene glycol and fatty alcohol condensation product, hydrogen peroxide, a quinoxaline compound and/or p-hydroxyacetanilide into the step (1), and supplementing the residual amount of water to 1000mL to obtain the compound.
