Embodiment 1

[0028] The low-temperature synergistic compound amine disinfectant provided by the present embodiment is composed of the following components by weight percentage:

[0029] Table 1

[0030] raw material content(%) Didecyldimethylammonium chloride 1 N-dodecyl-1,3-propanediamine 2 Isopropanol 5 E-1320 5 Benzotriazole 0.1 water 86.9

[0031] The preparation method of the low-temperature synergistic complex amine disinfectant solution provided in this example is: first stir and mix isopropanol and E-1320, and let it stand for 10 minutes at normal temperature and pressure; then add double decyl dimethyl ammonium chloride in sequence Stir and mix, add N-dodecyl-1,3-propanediamine, stir and mix, add benzotriazole, stir and mix, finally add water, filter and pack. The above preparation method strictly controls the adding sequence of each component, so that the quaternary ammonium salt is fully dissolved and mixed with other component...

Embodiment 2

[0033] The low-temperature synergistic compound amine disinfectant provided by the present embodiment is composed of the following components by weight percentage:

[0034] Table 2

[0035] raw material content(%) Benzalkonium chloride 3 N-dodecyl-1,3-propanediamine 1.6 ethanol 4 E-1304 4 Phosphonic acid 0.4 water 87

[0036] The preparation method of the low-temperature synergistic compound amine disinfectant provided in this implementation is: stir and mix ethanol and E-1304, let it stand for 12 minutes at normal temperature and pressure, then add benzalkonium chloride in turn to stir and mix, add N-dec Stir dialkyl-1,3-propanediamine, add phosphine carboxylic acid, stir and mix, finally add water, filter and pack.

Embodiment 3

[0038] The low-temperature synergistic compound amine disinfectant provided by the present embodiment is composed of the following components by weight percentage:

[0039] table 3

[0040] raw material content(%) Benzalkonium Bromide 5 N-dodecyl-1,3-propanediamine 1.2 ethylene glycol 2.8 E-1306 3 Benzotriazole 0.4 Phosphonic acid 0.2 water 87.4

[0041] The preparation method of the low-temperature synergistic compound amine disinfectant provided in this example is: stir and mix ethylene glycol and E-1306, let stand at room temperature and pressure for 10 minutes to fully dissolve ethylene glycol and E-1306, and then add benzene Zalkonium bromide, stir well, add N-dodecyl-1,3-propanediamine, stir well, add benzotriazole, phosphine carboxylic acid, stir well, finally add water, filter and pack .

Abstract

The invention discloses a low-temperature synergistic compound amine disinfectant and a preparation method thereof, which belong to the technical field of disinfectant preparation. The low-temperature synergistic compound amine disinfectant comprises the following raw materials by weight: 1%-10% of quaternary ammonium salt, 0.2%-2% of N-dodecyl-1, 3-propane diamine, 1%-5% of a cosolvent, 1%-5% of a nonionic surfactant, and water complementing to 100%.. The quaternary ammonium salt is selected from benzalkonium bromide, benzalkonium chloride, octyl decyl dimethyl ammonium chloride, didecyl dimethyl ammonium chloride and didecyl dimethyl ammonium bromide. According to the low-temperature synergistic compound amine disinfectant and the preparation method thereof provided by the invention, the quaternary ammonium salt fully exerts the sterilization performance under proper dissolution concentration, viscosity and pH, the disinfection effect of the disinfectant in a low-temperature environment is improved, the use concentration is relatively low, the disinfection effect is obvious within limited action time, the corrosion to the surface of an object is small, and the disinfectant is especially suitable for low-temperature environment disinfection of refrigerators, cold-chain transportation equipment and the like.

Description

technical field [0001] The invention relates to a low-temperature synergistic compound amine disinfectant and a preparation method thereof, belonging to the technical field of disinfectant preparation. Background technique [0002] Since the emergence of the new crown epidemic, low temperature and cold chain disinfection have become the focus of epidemic prevention and control. This is because many viruses, including the new crown virus, are resistant to cold and heat. The virus itself does not have a cell structure. The ice crystals produced during this time will not only fail to kill the virus, but will prolong the survival time of the virus on the item. Cold-chain food and transportation equipment in a low-temperature state are at risk of being contaminated by the new coronavirus during production, loading and unloading, transportation, storage, and sales. Nucleic acid positive for the new coronavirus was detected in samples of imported cold-chain food packaging in many p...
