Problems solved by technology

[0003] At present, the concentration of peracetic acid in the market is about 20%, and the stability is not good, generally ranging from 3 months to 1 year
In the prior art, common stabilizers such as octahydroxyquinoline are added to improve the stability of peracetic acid disinfectant, thereby prolonging the service life, but octahydroxyquinoline has a carcinogenic risk and has been banned in some European countries
[0004] In addition, the inventors of the present invention have found that when peracetic acid disinfectant is used to disinfect the surface of objects, especially smooth surfaces (such as glass, etc.), the liquid disinfectant is easy to flow down along the smooth surface, because it cannot be guaranteed to be consistent with The action time of the surface to be sterilized reduces the disinfection effect

Abstract

The invention discloses a foam type peracetic acid disinfectant as well as a preparation method and a use method thereof. The foam type peracetic acid disinfectant comprises 35wt%-45wt% of hydrogen peroxide, 30-40wt% of acetic acid, 2wt%-5wt% of a stabilizer, 1wt%-5wt% of phosphoric acid or sulfuric acid, 0.1wt%-0.4 wt% of ethylenediamine tetra (methylene phosphonic acid), 3wt%-8wt% of disodium 4-dodecyl-2,4'-oxydibenzenesulfonate, 0.1%-0.5% of perfluoroalkyl ethanol polyoxyethylene ether amine sodium phosphate and the balance of water. The foam type peracetic acid disinfectant provided by the invention is low in ecological toxicity, environment-friendly, easy to store, long in service cycle and good in stability, the diluted spraying liquid can maintain a foam form of more than 5 minutes on the surface of an object, the sterilization action time of peracetic acid is prolonged, the sterilization and disinfection effects are effectively ensured, and the practicability is good.

Description

technical field [0001] The invention relates to the technical field of disinfectant products, in particular to a foam-type peracetic acid disinfectant and its preparation method and use method. Background technique [0002] Peracetic acid is a broad-spectrum, high-efficiency disinfectant with a chemical formula of CH3COOOH and a relative molecular mass of 76.0518. It is a strong oxidant and has unstable chemical properties. Peracetic acid disinfectant is environmentally friendly and non-polluting. It can be used for sterilization and disinfection of medical equipment, and can also be used for preventive disinfection in epidemic areas and isolation areas. [0003] At present, the concentration of peracetic acid on the market is about 20%, and the stability is not good, generally ranging from 3 months to 1 year. In the prior art, common stabilizers such as octahydroxyquinoline are added to improve the stability of peracetic acid disinfectant, thereby prolonging the service li...
