Low-temperature disinfectant as well as preparation and application thereof

Abstract

The invention provides a low-temperature disinfectant as well as preparation and application thereof. The effective chlorine concentration of the low-temperature disinfectant ranges from 3600 mg/L to 5000 mg/L; 100 mL of the low-temperature disinfectant contains 29-35 g of calcium chloride, 0.1-0.5 g of quaternary ammonium salt, 10-30 mL of ethyl alcohol and10-20 mL of ethylene glycol, with the balance being water; and the low-temperature disinfectant may also include sodium chloride. A disinfectant and an anti-freezing agent adopted by the low-temperature disinfectant provided by the invention are conventional chemical reagents, so the low-temperature disinfectant is clear in toxicological safety and does not contain substances with strong toxicity; after proportioning according to a relevant formula, the problem of explosion does not exist; and the low-temperature disinfectant is effective at a low temperature of -40 DEG C. The low-temperature disinfectant disclosed by the invention is not frozen at a low temperature, is suitable for sterilizing a low-temperature refrigerator environment of -40 DEG C and sterilizing the surface of an outer package of goods at a low temperature of -40 DEG C, and can effectively kill pathogenic bacteria such as staphylococcus aureus and escherichia coli and coronavirus.

Description

technical field [0001] The invention belongs to the field of disinfectants, and in particular relates to a low-temperature disinfectant and its preparation and application. Background technique [0002] All current outbreaks are related to importation. Input mainly through two channels - people and things. The problem of human input is beginning to be handy through strategies such as restricting the flow of people, health monitoring (including nucleic acid testing), and centralized medical observation, but there are still difficulties in the control of "things". Many recent outbreaks are basically related to the import of viruses on "things". [0003] Cold temperatures prolong the survival time of viruses on items. Problems such as cold chain items, cold seasons, and alpine regions have emerged one after another. [0004] Routine disinfection is room temperature, high temperature disinfection. At present, the documents on low-temperature disinfection do not specify the ...

Problems solved by technology

Not long ago, hydrogen peroxide fumigation was called "experience" and tried to be promoted nationwide, but it has not been evaluated for the real low-temperature disinfection effect, and there are also potential safety hazards caused by excessively high concentrations required for disinfection (hydrogen peroxide concentration > 8% for hazardous chemicals)

[0006] Chlorine dioxide (500mg/L) is recommended for disinfection of food outer packaging in relevant regulations, but in
