Abstract

The invention discloses a stable peroxyacetic acid disinfectant and a production method thereof, and belongs to the technical field of disinfectants. The developed stable peroxyacetic acid disinfectant is composed of the following raw materials in parts by weight: 4-6 parts of persulfate, 2-5 parts of organic zinc, 3-5 parts of sepiolite, 15-30 parts of peroxyacetic acid, 3-5 parts of glacial acetic acid, 0.6-0.8 part of a surfactant and 200-300 parts of gelatin dispersion liquid; and the sepiolite can be acid-modified sepiolite, during production, under a condition of temperature of 40-50 DEGC, the persulfate, the organic zinc, the sepiolite, the peroxyacetic acid, the glacial acetic acid and the surfactant are sequentially added into the gelatin dispersion liquid, after adding is completed, a pH value is adjusted to be a gelatin isoelectric point, then after ultrasonic dispersion is conducted, under a condition of temperature of 0-6 DEG C, refrigeration is conducted for 8-12 h, discharging is conducted, and sealed storage is conducted to obtain the stable peroxyacetic acid disinfectant.

Description

technical field [0001] The invention discloses a stable peracetic acid disinfectant and a preparation method thereof, belonging to the technical field of disinfectants. Background technique [0002] Peracetic acid (PAA) disinfectant, as a disinfectant with the advantages of high efficiency, broad spectrum, safety, and no residual pollutants, has been used in the field of disinfection at home and abroad for more than half a century. Prevention and control, as well as hygiene and anticorrosion in the food processing industry, all play an important role. In recent years, the application of peracetic acid in some special medical devices in medical institutions, such as flexible endoscopes, hemodialysis systems, disinfection of epidemic foci, and disinfection of pipelines, aseptic packaging, and venues in food processing enterprises, has been continuously expanded. Research literature Also increasing. Due to its high efficiency, broad spectrum, safety, and no secondary pollutio...
