Problems solved by technology

[0005] At present, the hydrogen peroxide and peracetic acid mixed disinfectants sold in the domestic market are generally in binary packaging, that is, their products are divided into two components, A and B, which are stored separately at ordinary times, and put them away 24 to 48 hours before use Mixed, however, the concentration of peracetic acid in this type of product is higher, generally more than 15%, therefore, can not store for a long time, must mix and use now (Lan Zhanhua, Science of Travel Medicine, 2011.2)
In addition, in actual application, it can only be prepared according to the required amount, which brings inconvenience to use and limits the application of hydrogen peroxide and ethylene peroxide mixed disinfectant
In addition, there are also merchants who sell hydrogen peroxide and peracetic acid mixed disinfectants in one-yuan packages, but the one-yuan packaged hydrogen peroxide and peracetic acid mixed disinfect

Embodiment 1

[0080] Raw material preparation: take by weight percentage:

[0081] Hydrogen peroxide (concentration: 35%): 72%

[0082] Acetic acid: 12%

[0083] Sulfuric acid: 1%

[0084] Ethylenediaminetetramethylenephosphonic acid: 2%

[0085] Sodium Lauryl Sulfate: 1%

[0086] water 12%

[0087] Preparation Process:

[0088] Mix the weighed hydrogen peroxide, acetic acid and sulfuric acid, stir the reaction, then dissolve ethylenediamine tetramethylene phosphonic acid and sodium dodecylsulfonate in water, add them to the above reaction system after dissolving, and Stir for 12 to 36 hours and take samples for measurement. The content of peracetic acid reaches 4-7%, the content of hydrogen peroxide reaches 25-30%, and when the pH is less than 3, it is qualified. Then filter it with a filter membrane with a pore size of 0.2 microns and pack it into the warehouse. .

Embodiment 2

[0090] Raw material preparation: take by weight percentage:

[0091] Hydrogen peroxide (concentration: 40%): 75%

[0092] Acetic acid: 15%

[0093] Sulfuric acid: 0.1%

[0094] Hydroxycresyl diphosphonic acid: 1%

[0095] Sodium pyrophosphate: 1%

[0096] Sodium octane sulfonate: 1%

[0097] Deionized water: 6.9%

[0098] The preparation process is the same as in Example 1 (note: after the system reaction is balanced, peracetic acid is produced, and the concentration of hydrogen peroxide and acetic acid will be lower than the concentration when adding, so as to reach the index in the claims. The same below).

Embodiment 3

[0100] Raw material preparation: take by weight percentage:

[0101] Hydrogen peroxide (concentration: 50%): 80%

[0102] Acetic acid: 10%

[0103] Sulfuric acid: 0.5%

[0104] Hydroxyethylene diphosphonic acid: 0.5%

[0105] Pyrophosphoric acid: 0.5%

[0106] Sodium dodecylbenzenesulfonate: 0.5%

[0107] Distilled water: 8%

[0108] The preparation process is the same as in Example 1.

Abstract

The invention relates to a hydrogen peroxide and peracetic acid mixed disinfectant and a preparation method of the disinfectant. The disinfectant is prepared by the steps of mixing hydrogen peroxide, acetic acid and sulfuric acid at the room temperature to prepare mixture containing peracetic acid and hydrogen peroxide, feeding a stabilizer and a surface active agent into the mixture containing the peracetic acid and the hydrogen peroxide, and mixing. The mixed disinfectant comprises 3-9g/ 100g peracetic acid, 20-35g/ 100g hydrogen peroxide, 5-12g/ 100g acetic acid, 0.1-2g/ 100g sulfuric acid, 0.05-2g/ 100g stabilizer, 0.05-2g/ 100g surface active agent and the balance of water. The hydrogen peroxide and peracetic acid mixed disinfectant is good in stability, is capable of rapidly killing various microorganisms such as bacteria, mould, yeast, spores and the like, and is safe, non-toxic and free from secondary pollution.

Description

technical field [0001] The invention belongs to the field of chemical disinfectants, in particular to a hydrogen peroxide and peracetic acid mixed disinfectant and a preparation method thereof. Background technique [0002] In our country, food safety and drug safety problems are becoming more and more serious, and the public is paying more and more attention. The types and residues of fungicides and disinfectants used in the process of food and drug processing are also more and more popular. Therefore, as personnel and manufacturers of R&D and production of fungicides and disinfectants, they have the responsibility and obligation to find and develop a high-efficiency, low-toxicity, and residue-free product to meet the needs of society. [0003] At present, commonly used disinfectants in the field of disinfectants include chlorine-containing disinfectants (such as sodium hypochlorite, sodium dichloroisocyanurate, chlorine dioxide), aldehyde disinfectants (such as formaldehyd...
