Problems solved by technology

[0006] However, according to the literature, it is known that low concentrations of hydrogen peroxide cannot inactivate non-lipid-enveloped hydrophilic viruses (poliomyelitis virus), and quaternary ammonium salts cannot inactivate non-lipid-enveloped hydrophilic viruses (polioviruses). virus), therefore, the present invention provides a compound disinfectant containing low concentration of hydrogen peroxide and quaternary ammonium salt, which can inactivate no lipid envelope hydrophilic virus (poliomyelitis virus), Can be used for high-efficiency sterilization in home environment and hospital environment

[0029] Specifically, the present invention provides a technical solution: a medical antiviral disinfectant containing low-concentration hydrogen peroxide. Active agent, 1.0-5.0% bactericidal synergist, 0.3-1.0% stabilizer, 0.01%-1.0% metal corrosion inhibitor, 0.1-1.0% acid-base regulator and 86-98.19% purified water;

[0030] Specifically, the stabilizer includes at least one of hexamethylenediaminetetramethylenephosphonic acid, diethylenetriaminepentamethylenephosphonic acid, aminotrimethylenephosphonic acid and hydroxyethylenediphosphonic acid, and the surfactant Including lauryl dimethyl amine oxide, cocamide dimethyl amine oxide, sodium lauryl sulfate, sodium lauryl sulfonate, sodium dodecyl benzenecyclonate and dodecyl benzene sulfonic acid At least one of, the bactericidal synergist includes at least one of benzalkonium chloride, didecyldimethylammonium chloride and ethanol, and the metal corrosion inhibitor includes triethanolamine, diethanolamine, sodium benzoate and ...

Embodiment 2

[0036] Under the conditions of 10-25°C and 1 atmospheric pressure, the specific preparation method of the disinfectant comprises the following steps:

[0037] S1. First add 60g of purified water into the batching tank, then add 0.25g of hexamethylenediaminetetramethylene phosphoric acid into the batching tank and stir for 10min until completely dissolved;

[0038] S2. Add 0.5g of lauryl dimethyl amine oxide, 0.25g of didecyl dimethyl ammonium chloride, 0.2g of triethanolamine and 0.11g of dipotassium hydrogen phosphate to the solution of step S1, and stir for 10 minutes until completely dissolved ;

[0039] S3. Add 0.5 g of hydrogen peroxide to the solution in step S2, then add purified water to 100 g, stir for 10-15 min until the mixture is uniform, and let stand for 30 min to obtain a clear and transparent solution with a pH value of 3.5-4.5.

Embodiment 3

[0041] Under the conditions of 10-25°C and 1 atmospheric pressure, the specific preparation method of the disinfectant comprises the following steps:

[0042] S1. First add 60g of purified water into the batching tank, then add 0.25g of hexamethylenediaminetetramethylene phosphoric acid into the batching tank and stir for 10min until completely dissolved;

Abstract

The invention discloses a medical antiviral disinfectant containing low-concentration hydrogen peroxide, which comprises the following components in percentage by weight: 0.3 to 3.0 percent of hydrogen peroxide, 0.1 to 5.0 percent of surfactant, 1.0 to 5.0 percent of bactericidal synergist, 0.3 to 1.0 percent of stabilizer, 0.01 to 1.0 percent of metal corrosion inhibitor, 0.1 to 1.0 percent of acid-base regulator and 86 to 98.19 percent of purified water. The low-concentration hydrogen peroxide compounded quaternary ammonium salt disinfectant is simple in preparation process and stable in product property, the environment surface can be disinfected in a spraying mode or a wiping mode, the low-content hydrogen peroxide is non-irritant to skin and non-corrosive to various environment surfaces, the disinfectant does not need to be diluted during use, the bactericidal effect is rapid, and the poliomyelitis virus 1mi < n > can be killed, so that the disinfectant is an ideal disinfection product for disinfecting the environment of families and hospitals.

Description

technical field [0001] The invention relates to the technical field of disinfectants, in particular to a medical antiviral disinfectant containing low-concentration hydrogen peroxide. Background technique [0002] Disinfectant is a drug used to kill pathogenic microorganisms on the transmission medium. It eliminates pathogenic microorganisms outside the human body, cuts off the transmission route of infectious diseases, and achieves the purpose of controlling infectious diseases. The situation of the prevention and control of the new crown pneumonia epidemic is still severe and complicated. In addition to wearing masks and washing hands frequently, disinfection of the living environment is also a very effective means of controlling the epidemic. [0003] The National Health and Medical Commission clearly stated in the diagnosis and treatment plan that "the new coronavirus is sensitive to ultraviolet rays and heat. Lipid solvents such as 56°C for 30 minutes, ether, 75% ethano...
