Abstract

The invention belongs to the field of chemical disinfecting product preparations, and in particular relates to a peracetic acid disinfectant and a preparation method thereof. The peracetic acid disinfectant includes an agent A and an agent B, wherein the agent A consists of the following components: peracetic acid, hydrogen peroxide, acetic acid, a stabilizing agent and de-ionized water; the agent B consists of the following components: trisodium phosphate, a complexing agent, a metal corrosion inhibitor, a stabilizing agent and de-ionized water. The peracetic acid disinfectant greatly improves a problem that conventional peracetic acid is instable and easy to decompose, and simultaneously effectively reduces corrosion of peracetic acid on metals. A practical solution obtained by mixing the agent A and the agent B is basically free from corrosion on molybdenum-chromium alloy, stainless steel, PEEK (polyetheretherketone), PPSU (Polyphenylsulphone) and other endoscope materials, and greatly improves limitation of the traditional peracetic acid due to corrosion. Furthermore, the invention provides the preparation method of the peracetic acid disinfectant, which is reasonable in design, simple in process and easy to realize industrial production.

Description

technical field [0001] The invention belongs to the field of chemical disinfection product preparations, and in particular relates to a peracetic acid disinfectant and a preparation method thereof. Background technique [0002] Endoscopic diagnosis and treatment have been popularized and widely used in clinic. Only the American Society of Gastrointestinal Endoscopy estimates that more than 10 million people receive gastrointestinal endoscopic diagnosis and treatment every year. However, due to the fine structure and special materials of the endoscope, many parts are not resistant to high temperature and are afraid of corrosion, high cost, frequent use and turnover, etc., it brings many difficulties to endoscope disinfection and sterilization, which is an important way to cause iatrogenic transmission of hospital cross-infection . [0003] According to reports, nosocomial infections caused by endoscopy include: Salmonella, Pseudomonas aeruginosa, Mycobacterium, HBV, HCV, HIV...
