Problems solved by technology

[0004] At present, there are few studies on disinfection technology under low temperature conditions. The main method is to add a certain proportion of organic solvents such as ethanol, ethylene glycol, isopropanol, glycerin, etc. to the disinfection solution to lower the freezing point. can be purchased
This has become a technical difficulty restricting the disinfection of the new coronavirus under cold chain conditions and winter low temperature environment

Abstract

The invention discloses a low-temperature disinfection material and a preparation method thereof. The invention belongs to the technical field of disinfection materials, and particularly relates to apreparation method of a low-temperature disinfection material, which is simple in process, low in cost and wide in application range.According to the technical scheme, low-temperature materials, solvents, disinfection materials, corrosion inhibitors, stabilizers, passivators and the like are compounded, so that the sterilization disinfectant can effectively solve the problem that sterilization isnot ideal in a low-temperature environment (cold storage and cold chain links), and can be widely applied to efficient sterilization and disinfection under normal-temperature conditions and low-temperature conditions (-20 DEG C and even -40 DEG C).

Description

technical field [0001] The invention belongs to the field of preparation of disinfection materials, in particular to a low-temperature disinfection material and a preparation method thereof. Background technique [0002] Issues such as positive nucleic acid in cold chain food have made it more difficult to prevent the new crown epidemic. Therefore, sterilization and disinfection in low-temperature environments involved in various links of the cold chain is a new topic in 2020. For some commonly used room temperature disinfectants, low-temperature environments, especially sub-zero Below 18°C, it may have a significant impact on the disinfection effect, and the commonly used disinfection methods may not be able to meet the actual needs due to complete failure. Therefore, whether it is possible to achieve an efficient and ideal disinfecting effect under low temperature conditions, especially at extremely low temperatures (below -40°C), and to develop corresponding low-temperatu...
