Abstract

The invention discloses a stable low-corrosiveness sporicide and its preparation method. The sporicide comprises, by mass / volume (g / 100 ml), 4-15% of peroxyacetic acid, 20-40% of hydrogen peroxide, 1-3% of acetic acid, 1-3% of isooctanoic acid, 0.1-2% of a compound stabilizer, 0.05-1% of a corrosion inhibitor, an inorganic acid used to adjust the pH value to 1.1-1..3, and the balance of water without metal ion impurities. The sporicide is diluted 100 times when the sporicide is used. The main effective components of the sporicide are peroxyacetic acid and hydrogen peroxide, and the adjustment of the formula of the stabilizer and the corrosion inhibitor and the optimization of the pH value make the sporicide quickly kill bacteria and fungal spores and have a good killing effect on vegetative forms of common bacteria and fungi, and ensure good stability and low corrosiveness. The sporicide has the characteristics of good stability, low corrosiveness, wide antibacterial spectrum and simple production technology.

Description

technical field [0001] The invention relates to a disinfectant, in particular to a stable and low-corrosion sporicide and a preparation method thereof, belonging to the field of chemical disinfectants. Background technique [0002] There are many kinds of environmental microorganisms, and the methods of killing and removing microorganisms can be divided into physical disinfection methods and chemical disinfection methods. Physical disinfection methods such as thermal sterilization and sterilizing filtration have good sterilization effects, but they are only suitable for small-volume items and liquid materials. Chemical disinfection is mainly used in environmental disinfection. When disinfecting environments with strict microbial limits (such as food and pharmaceutical production environments), it is not enough to kill bacteria and fungal propagules, and the residues of bacteria and fungal spores will also cause microbial contamination. There are many types of disinfectants...
