Embodiment 1

[0030] A method for preparing a bactericide for controlling blue skin erythema, comprising the following steps:

[0031] 1) Mixing: In terms of the weight percentage of each component, the fungicide CIT / MIT (Kasone, the content is 14%, the chlorine ratio is 3:1): 15 kg, the fungicide DBNPA (2,2-dibromo-3- Nitrilopropionamide, white crystalline powder, content: 99%): 1.5 kg, stabilizer Mg (NO 3 ) 2 (magnesium nitrate): 3 kg, solvent polyethylene glycol 400: 6 kg, water: 74.5 kg for preliminary mixing;

[0032] 2) Stirring: Put the preliminarily mixed solution in step 1) into a high-speed disperser, the speed of the high-speed disperser is 600 rpm, and the rotation time is 15 minutes;

[0033] 3) Packaging: pour the solution mixed by the high-speed disperser into the packaging barrel, and the filling is completed.

[0034] The process from raw fur to blue leather is: raw fur, soaking, degreasing, fleshing, depilation, liming, deliming, softening, pickling, chrome tanning, blu...

Embodiment 2

[0037] Concrete steps are with embodiment 1, and difference is: mix in the step (1): in each component weight percentage, bacterium agent CIT / MIT: 30 kilograms, bactericide DBNPA: 4 kilograms, stabilizer Mg (NO 3 ) 2 : 10 kg, solvent polyethylene glycol 400: 8 kg, water: 48 kg.

[0038] According to the second embodiment, basically the same effect as that of the first embodiment can be achieved.

Embodiment 3

[0040] Concrete steps are with embodiment 1, and difference is: mix in the step (1): in each component weight percent, bacterium agent CIT / MIT: 45 kilograms, bactericide DBNPA: 8 kilograms, stabilizer Mg (NO 3 ) 2 : 20 kg, solvent polyethylene glycol 400: 15 kg, water: 12 kg.

[0041] According to the third embodiment, basically the same effect as that of the first or second embodiment can be achieved.

Abstract

The invention discloses a bactericide for controlling red spots of wet blue leather. The bactericide is characterized by comprising, by weight, 15-50% of bactericide CIT / MIT, 1-8% of bactericide DBNPA, 1-20% of stabilizers Mg(NO<3>)<2>, 5-15% of solvents polyethylene glycol 400 and 10-80% of water. The bactericide has the advantages that the bactericide is environmentally friendly, is high in efficiency and can be added into raw materials fur when the raw materials fur are soaked in water, and accordingly breeding of the red spots of the wet blue leather can be effectively controlled when the wet blue leather is obtained.

Description

[0001] 【Technical field】 [0002] The invention relates to the field of fungicides, in particular to a fungicide for controlling blue skin erythema and a preparation method thereof. [0003] 【Background technique】 [0004] In the long process of human tanning history, the real use of fungicides is only in the last 100 years, but people can realize that the bacteria existing in the water body have a certain history of damage to the grain surface of fur. Early people changed the water frequently to reduce the damage of bacteria to the fur grain. The next process is that people add some bleaching powder in the process of soaking the fur, which is indeed more effective than changing the water to control bacteria in the early stage, and it also reduces a lot of water waste. However, with the advancement of science and technology and the continuous improvement of material science, organic sulfides have officially entered the leather industry and become the main fungicides for soakin...
