Problems solved by technology

For perennial frozen areas and some cold-chain transported goods, commonly used disinfectants such as bleaching powder and sodium hypochlorite are not resistant to low temperature, and the disinfecting effect is reduced or even invalid under low temperature conditions. To solve this problem, the countermeasure of increasing the concentration of disinfectant is usually adopted , the direct consequences of this are the increase in the cost of disinfection at the port, the serious pollution to the environment, and the damage and impact on the goods caused by the residue of high-concentration disinfectants on the goods.

Embodiment 1

[0017] A. 1 part of polyhexamethyleneguanidine and 100 parts of water are mixed to obtain a concentration of 1% polyhexamethyleneguanidine mother liquor;

[0018] B. 0.5 part of trivalent silver ion and 100 parts of water are mixed to obtain a trivalent silver ion solution with a concentration of 0.5%;

[0019] C. Mix 1 part of polyhexamethylene guanidine mother liquor, 1 part of trivalent silver ion solution, 500 parts of water, and 500 parts of alcohol solution with a concentration of 80% to obtain a disinfectant that can be used in a low-temperature cold chain. The resulting disinfection The agent does not freeze at -20°C, and the killing rate of influenza virus can reach more than 93%.

Abstract

The invention relates to a disinfectant capable of being used in a low-temperature cold chain and a preparation method of the disinfectant. The solvent of the disinfectant is water, and the solute of the disinfectant comprises alcohol, polyhexamethylene guanidine and trivalent silver ions. In the disinfectant, the concentration of the alcohol is 20%-40%, the concentration of the polyhexamethylene is 10-50 ppm, and the concentration of the trivalent silver ions is 10-50 ppm. The disinfectant is not frozen at the temperature of -25 DEG C to 0 DEG C, has excellent properties of broad spectrum, long acting, no toxicity and harmlessness at the normal temperature and the low temperature of -25 DEG C to 0 DEG C, and has extremely high bacterium killing capacity, the bacterium killing effect of the disinfectant is not weakened at the temperature of -25 DEG C to 0 DEG C, and the preparation method is simple and easy to implement.

Description

technical field [0001] The invention relates to a disinfectant, in particular to a disinfectant which can be used in a low-temperature cold chain and a preparation method thereof. Background technique [0002] In today's world of trade globalization, all parts of the world are closely connected by the transportation network. With the development of trade logistics, viruses and bacteria that appear in any place will be transmitted to various places through the transportation network. Disinfect it beforehand to prevent the spread of viruses and bacteria. For perennial frozen areas and some cold-chain transported goods, commonly used disinfectants such as bleaching powder and sodium hypochlorite are not resistant to low temperature, and the disinfecting effect is reduced or even invalid under low temperature conditions. To solve this problem, the countermeasure of increasing the concentration of disinfectant is usually adopted , The direct consequences of this are the increase ...
