Abstract

The invention belongs to the technical field of disinfectant formulas and preparation thereof, and discloses a high-stability chlorine-containing disinfectant formula and a preparation method thereof.A plurality of components such as 1-hydroxyethylidene-1, 1-diphosphonic acid, ethylenediamine tetramethylene phosphonic acid sodium salt, sodium silicate, sodium carbonate, sodium chlorate, sodium chloride and sodium hydroxide are added into the disinfectant as a composite inhibitor to reduce decomposition reaction and disproportionation reaction of sodium hypochlorite in the disinfectant, so that the service life of the disinfectant is guaranteed; by compounding multiple components, the stability of the system is guaranteed, and the storage time of the stock solution and the diluent is prolonged. The preparation method of the disinfectant provided by the invention is simple to operate, and the stability and the sterilization effect of the disinfectant are greatly improved through different adding sequences, limited reaction time and selection of specific pH value parameters.

Description

technical field [0001] The invention belongs to the technical field of disinfectant formula and its preparation, and relates to a highly stable chlorine-containing disinfectant formula and a preparation method thereof. Background technique [0002] Currently commercially available chlorine-containing disinfectants still have some obvious deficiencies in terms of stability. During storage, transportation and use, the available chlorine content often decreases by more than 30% within 14 days at 54°C. The instability of the product and the rapid loss of active ingredients greatly reduce the disinfection ability of the product, and the disinfection effect cannot be guaranteed. The market demand for chlorine-containing disinfectants is huge and must-have for households. There is a great need for chlorine-containing and stable disinfectant products in the market. Contents of the invention [0003] In order to overcome the deficiencies in the prior art, the invention provides a ...
