Abstract

The invention discloses a biochemical decontamination agent and a preparation method of the biochemical decontamination agent, and belongs to the application field of sanitizers. Components and mass percentage contents of the components are shown as below on the basis of taking the total mass of the decontamination agent as 100%: 15.5% to 30% of 1-Bromo-3-chloro-5,5-dimethylhydantoin; 10% to 25% of dibromohydantoin; 20% to 30% of sodium percarbonate; 20% to 30% of sodium carbonate; 2% to 6.5% of chelating agent; 0% to 10% of surfactant. Mixing the sodium carbonate and the sodium percarbonate evenly after being screened under the condition of 20 Celsius degrees to 25 Celsius degrees, a constant pressure, and the relative humidity equal to or less than 40, and mixture is obtained. Adding the dibromohydantion, the 1-Bromo-3-chloro-5,5-dimethylhydantoin, the surfactant and the chelating agent into the mixture sequentially under the temperature of 20 Celsius degrees to 30 Celsius degrees, the constant pressure and the relative humidity equal to or less than 40 evenly, and therefore the biochemical decontamination agent is obtained. The biochemical decontamination agent is small in metal corrosivity, does not produce residual toxicity after usage, and does not cause secondary pollution.

Description

technical field [0001] The invention relates to a biochemical decontaminant and a preparation method thereof, belonging to the field of disinfectant applications. Background technique [0002] At present, there are three main categories of domestic decontaminants: (1) hypochlorite and organic chloramines with oxidative chlorination as the disinfection mechanism; (2) organic superalkali systems and caustic Alkali; (3) Adsorption disinfection powder. The above decontamination agents can basically meet the requirements of emergency decontamination in terms of decontamination effect, but there are problems such as strong corrosion to equipment and large pollution in terms of performance. Therefore need to research the new detergent that can solve these problems. Contents of the invention [0003] Aiming at the problems that the existing decontaminants have strong corrosiveness to equipment and heavy pollution, the object of the present invention is to provide a biochemical d...
