Abstract

The invention discloses a low-temperature quaternary ammonium salt disinfectant and a preparation method thereof, and belongs to the technical field of disinfection. The quaternary ammonium salt disinfectant comprises the following components in percentage by weight: 0.1-0.6% of quaternary ammonium salt, 1-5% of a curing agent, 0.1-0.5% of a synergist, 20-50% of an anti-freezing agent and the balance of water. The quaternary ammonium salt disinfectant can be obtained by sequentially adding the quaternary ammonium salt, the curing agent, the synergist and the anti-freezing agent into water and uniformly stirring. The quaternary ammonium salt disinfectant is not frozen under the condition of-23 DEG C, can keep an excellent sterilizing effect, is lasting in antibacterial effect, relatively low in corrosivity, good in stability and convenient to operate, does not need to be wiped and cleaned after acting on the surface of an object, has the advantages of safety, environment friendliness, high efficiency, no toxicity, no odor and the like, and has a wide application prospect.

Description

technical field [0001] The invention relates to the technical field of disinfection, in particular to a low-temperature quaternary ammonium salt 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 temperature and freeze-dried. 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.
