Hydrogen peroxide disinfectant and preparation method thereof

Abstract

The invention discloses a hydrogen peroxide disinfectant. Thehydrogen peroxide disinfectantis composed of the following components in percentage by weight: 0.3-0.6% of hydrogen peroxide, 0.01%-0.05% of zinc ions / copper ions, 0.05-0.50% of citric acid, 0.4-1.5% of a penetrating agent, 0.1-1.0% of a surfactant and 0.04-0.1% of a stabilizing agent, with the balance being purified water. The inventionalso discloses a preparation method of the hydrogen peroxide disinfectant. The hydrogen peroxide disinfectant disclosed by the invention can be used for rapidly killing mycobacteria, and has good stability, catalyst resistance and strong anti-interference capability.

Description

technical field [0001] The invention relates to the technical field of chemical disinfection of environmental surfaces and air, in particular to a highly stable hydrogen peroxide disinfectant capable of rapidly killing mycobacteria and a preparation method thereof. Background technique [0002] At present, the chemical disinfectants used in the disinfection of environmental surfaces mainly include quaternary ammonium salts and sodium hypochlorite. Among them, quaternary ammonium salt disinfectants generally can only achieve low-level disinfection and cannot kill mycobacteria; although sodium hypochlorite disinfectants can achieve high-level disinfection, due to their strong alkali and strong oxidation characteristics, they are not effective for many such as Non-stainless metals are very corrosive, which limits their scope of use. [0003] Another widely used surface disinfectant is hydrogen peroxide disinfectant, wherein hydrogen peroxide is safe and has no residue, and its...

AI Technical Summary

Problems solved by technology

However, the disinfection effect of low-concentration hydrogen peroxide disinfectant is generally not ideal, the anti-interference ability is poor, and it cannot kill mycobacteria. In order to improve the sterilization effect, the concentration of hydrogen peroxide needs to be increased. Therefore, the concentration of hydrogen peroxide is high enough to meet the requirements of its bactericidal ability. Therefore, medical hydrogen peroxide generally contains 3% hydrogen peroxide. Hydrogen peroxide at this concentration has strong oxidizing properties. In terms of safety Potentially dangerous

In addition, in order to improve the disinfection effect of hydrogen peroxide, other synergistic substances, such as silver ions, etc. are generally added, which will cause the instability of hydrogen peroxide solution, thereby shortening the storage period of hydrogen peroxide and reducing its reliability. sex

And as a precious metal, silver is scarce in resources and does not have the conditions for large-scale use
