Abstract

The invention relates to a composite low-temperature disinfectant and a preparation method thereof. The invention belongs to the technical field of disinfection materials, and particularly relates tothe composite low-temperature disinfectant which is simple in process, wide in application range, efficient at low temperature, broad-spectrum in sterilization and lasting in bacteriostasis and the preparation method of the disinfectant. According to the technical scheme, an organic low-temperature material and an inorganic low-temperature material are compounded into a low-temperature component,an inorganic material and a polymer are compounded into a disinfection component, and a corrosion inhibitor and a stabilizer are compounded, so that the disinfectant capable of remarkably killing bacteria at -20 DEG C is prepared. The invention predicts that the problem that a normal-temperature disinfectant cannot be used in low-temperature environments, refrigeration houses and cold chain linksin winter can be effectively solved.

Description

technical field [0001] The invention belongs to the field of preparation of disinfection materials, in particular to a composite low-temperature disinfectant and a preparation method thereof. Background technique [0002] The food industry is a people's livelihood industry that is related to the immediate needs of the public and economic and social stability. In the context of normalized epidemic prevention and control, the importance and urgency of food safety issues have reached unprecedented heights. [0003] An important part of the food safety issue is cold chain food safety. Cold chain disinfection is an important guarantee for cold chain food safety. Regarding cold chain disinfection, in addition to returning to normal temperature for disinfection and storage or direct incineration, destruction, and landfill, it is still necessary to disinfect the surface of all cold chain foods under low temperature conditions (even below -40°C). . The development of disinfectan...
