Example Embodiment
[0032] Another object of the present invention is to provide a method for preparing the disinfectant, the method comprising the following steps:
[0034] (2) Take an appropriate amount of hydrogen peroxide, silver nitrate colloidal solution and water, adjust the pH after mixing, and make up to the corresponding volume with water.
[0035] The final content of the hydrogen peroxide is 30wt%-50wt%, and the final content of silver nitrate is 0.01wt%-0.1wt%.
Example Embodiment
[0036] As a preferred embodiment of the present invention, the preparation method of the disinfectant includes the following steps:
[0037] (1) Prepare the colloidal silver complexing agent solution: Weigh an appropriate amount of the colloidal silver complexing agent into a beaker containing the required amount of water, and stir at 60°C until it is completely dissolved;
[0040] ① Measure a certain amount of water, adjust the pH to less than 1.5 with the phosphoric acid solution, and then heat the solution to 55°C;
[0041] ②Add silver nitrate to the solution obtained in ①, add the phosphoric acid solution after mixing, and stop adding the phosphoric acid solution when stirring to completely dissolve the silver nitrate;
[0042] ③Cool the solution obtained in ② to 30°C, add stabilizer, and stir until completely dissolved;
[0043] ④Add the colloidal silver complexing agent solution to...

Abstract
The present invention provides a disinfectant, which comprises hydrogen peroxide and a silver nitrate colloid, wherein the hydrogen peroxide content is 30-50 wt%, and the silver nitrate content is 0.01-0.1 wt%. According to the present invention, the disinfectant overcomes the defects of the single component, improves the disinfection effect and the solution stability, has strong sterilization capability, and rapidly acts; and the effective components and the pH value of the obtained are stable, silver ions cannot be precipitated after the long-time standing, and the stability test data and the disinfection effect data are stable. The invention further provides a preparation method of the disinfectant.
Description
technical field [0001] The invention relates to a disinfectant and its preparation method and application, belonging to the field of disinfectants. Background technique [0002] Disinfectants refer to preparations that can kill pathogenic microorganisms in the transmission medium and make them harmless. At present, there are many kinds of disinfectants on the market, and the commonly used disinfectants are mainly aldehydes, iodine, compound phenols, peroxides, chlorine-containing disinfectants, quaternary ammonium salts and other disinfectants. According to the classification of disinfection efficacy of disinfectants, peroxides and compound aldehydes are high-efficiency disinfectants; alcohols and iodine are medium-efficiency disinfectants; quaternary ammonium salts and phenols are low-efficiency disinfectants. But each of these disinfectants has its own drawbacks. For example, phenol preparations and chlorine-containing disinfectants are highly irritating and corrosive; f...
