Abstract

The invention discloses a wetting agent-containing low-corrosivity peracetic acid disinfectant and a preparation method thereof, and the peracetic acid disinfectant comprises the following components in percentage by mass: 15%-20% of hydrogen peroxide, 30%-40% of glacial acetic acid, 0.2%-2% of isomeric C10 alcohol polyoxyethylene polyoxypropylene ether, 0.5%-4% of an auxiliary agent, 0.2%-2% of persulfate, 1%-3% of a stabilizer and the balance of water. The auxiliary agent is selected from dodecyl guanidine hydrochloride or / and hexadecyl trimethyl ammonium chloride. The peracetic acid disinfectant provided by the invention has the advantages of rapid disinfection and sterilization and good effect, especially has the advantages of low corrosion to equipment, no residue, no toxicity, safety and reliability, and the peracetic acid disinfectant is simple in preparation process, convenient to operate and easy for industrial production.

Description

technical field [0001] The invention relates to the technical field of disinfection, and more particularly to a low-corrosive peracetic acid disinfectant containing a wetting agent and a preparation method thereof. Background technique [0002] Peracetic acid disinfectant belongs to peroxide type disinfectant. It has strong oxidizing ability, can effectively kill various microorganisms, and has the advantages of rapidity, high efficiency, and no residual harmful substances after decomposition. However, many single-component peracetic acid disinfectants on the market have very low surface activity, and the selectivity of binding with bacteria (bacterial intracellular enzymes) -SH groups is weak, so it is necessary to change the factors of protein and nucleic acid functional groups. , the action time required to inhibit its activity is longer. To achieve the corresponding disinfection effect, a higher concentration of disinfectant must be used, which will not only cause corro...
