Abstract

The invention discloses a low-temperature peracetic acid disinfectant and a preparation method thereof, and belongs to the technical field of disinfection. The peracetic acid disinfectant comprises the following components in percentage by weight: 0.1-2% of peracetic acid, 1-10% of hydrogen peroxide, 10-30% of an anti-freezing agent, 0.01-1% of a stabilizer, 0.1-1% of a corrosion inhibitor and the balance of water. The peracetic acid disinfectant can be obtained by sequentially adding the peracetic acid, the hydrogen peroxide, the stabilizer, the anti-freezing agent and the corrosion inhibitor into water and stirring well. The peracetic acid disinfectant is not frozen at -23 DEG C, can achieve a disinfection effect within a short time, is good in stability, low in corrosivity and convenient to operate, does not need to be cleaned after acting on the surface of an object, and has the advantages of being safe, environmentally friendly, efficient, non-toxic, odorless and the like.

Description

technical field [0001] The invention relates to the technical field of disinfection, in particular to a low-temperature peracetic acid disinfectant and a preparation method thereof. Background technique [0002] The 2019 novel coronavirus (SARS-CoV-2) is a virus containing a lipid membrane, and it is a lipophilic virus like hepatitis B virus and influenza virus. Symptoms of infection with the virus are generally fever, fatigue, dry cough, and gradual dyspnea. In severe cases, it manifests as acute respiratory distress syndrome, septic shock, metabolic acidosis that is difficult to correct, and coagulation dysfunction. [0003] Many viruses can be stored at -4°C for one month, frozen for several years, and can survive stably at ultra-low temperatures and freeze-dried conditions. In this process, although the virus cannot replicate, it can ensure that its own biological structure is not destroyed. Once it returns to normal temperature, it may still cause transmission.
