84 disinfectant and preparation method thereof

Abstract

The invention discloses an 84 disinfectant and a preparation method thereof. The 84 disinfectant is prepared from the following raw materials in parts by weight: 100 to 120 parts of sodium hypochlorite, 30 to 50 parts of sodium hydroxide, 5.5 to 6.5 parts of sodium metasilicate pentahydrate, 1.18 to 1.28 parts of trisodium phosphate and 810 to 870 parts of water. The invention further discloses the preparation method of the 84 disinfectant; the preparation method comprises the following steps: putting the sodium metasilicate pentahydrate, the trisodium phosphate and the sodium hypochlorite into a reactor and adding the water; stirring for 28min to 32min to completely dissolve solid matters; then adding the water into the reactor again and stirring for 17min to 21min to obtain a mixed solution A; adding the sodium hydroxide, the sodium hypochlorite and the mixed solution A into the water and mixing; after stirring for 28min to 35min, standing for 1.8h to 2.5h to obtain the 84 disinfectant. The 84 disinfectant prepared by the preparation method is characterized in that the disinfectant has good sterilization effect, strong stability and the like.

Description

technical field [0001] The invention relates to the field of disinfectant preparation, in particular to a 84 disinfectant solution and a preparation method thereof. Background technique [0002] Chlorine-containing disinfectants are the earliest and most widely used chemical disinfectants. They have the advantages of wide bactericidal spectrum, reliable bactericidal effect, simple production process, convenient use, and low price. Therefore, they have a wide range of applications and are enduring. At present, the chlorine-containing disinfectant with the largest sales volume in the domestic and foreign markets is sodium hypochlorite disinfectant, which is sold under the brand of "84 Disinfectant" in China and is widely used in households, medical institutions, industry, agriculture, food industry, pharmaceutical industry, and breeding industry and other fields. [0003] The main disadvantage of sodium hypochlorite solution is its poor stability. Because sodium hypochlorite ...

Problems solved by technology

[0003] The main disadvantage of sodium hypochlorite solution is its poor stability. Because sodium hypochlorite itself is easy to decompose, the chlorine gas generated by decomposition not only pollutes the environment but also poses a threat to human health, which limits the production, storage, transportation and use of sodium hypochlorite, making sterilization, disinfection and bleaching The effect is greatly reduced
