Example Embodiment

[0024] Example 1:

[0025] Step 1: 260 g of calcium chloride ultrasound was dispersed in 640 ml of pure water, and rapid ultrasound was stirred for 2 hours (the water bath temperature was 40 ° C), and the room temperature was exposed to 24 hours to obtain a solution A.

[0026] Step 2: 0.4 g of formic acid was added to 100 ml of pure water. Ultrasound was rapidly stirred for 5 hours (the water bath temperature was 60 ° C), and the room temperature was exposed to 24 hours to obtain a solution B.

[0027] Step 3: The above solution A and solution B mixed ultrasound vigorously stirred vigorously for 24 hours to give C.

[0028] Step 4: Mix the above solution C with 5 g sodium dichloride isocyanate to give a solution D.

[0029] Step 5: 0.5 g of polyacrylic acid was added to the above solution D to obtain a low temperature disinfection material.

Example Embodiment

[0030] Example 2:

[0031] Step 1: 30 g of sodium chloride and 240 g of calcium chloride ultrasound were dispersed in 630 ml of pure water, rapid ultrasound was stirred for 2 hours (the water bath temperature was 40 ° C), and the room temperature was exposed to 24 hours to obtain a solution A.

[0032] Step 2: 0.4 g of sodium nitrite was added to 100 ml of pure water. Ultrasound was rapidly stirred for 5 hours (the water bath temperature was 60 ° C), and the room temperature was exposed to 24 hours to give a solution B.

[0033] Step 3: The above solution A and solution B mixed ultrasound vigorously stirred vigorously for 24 hours to give C.

[0034] Step 4: Mix the above solution C with 5 g of trichloroisocyanic acid to give a solution D.

[0035] Step 5: 2 g of triethanolamine was added to the solution D to obtain a low temperature disinfection material.

Example Embodiment

[0036] Example 3:

[0037] Step 1: 20 g of sodium chloride and 250 g of calcium chloride ultrasound were dispersed in 630 mL of pure water, and the rapid ultrasound was stirred for 2 hours (the water bath temperature was 40 ° C), and at room temperature for 24 hours, the solution A was obtained.

[0038] Step 2: 0.5 g of sodium nitrite was added to 100 ml of pure water. The ultrasound was rapidly stirred for 5 hours (the water bath temperature was 60 ° C), and the room temperature was exposed to 24 hours to obtain a solution B.

[0039] Step 3: The above solution A and solution B mixed ultrasound vigorously stirred vigorously for 24 hours to give C.

[0040] Step 4: Mix the above solution C with 4.5 g of dichloroisocyanic acid to give a solution D.

[0041] Step 5: 0.5 g of sodium polyacrylate and 2.5 g of triethanolamine were added to the above solution D to obtain a low temperature disinfection material.

[0042] It should be noted that the various components can select a plural...

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...
