Problems solved by technology

[0003] However, in the actual application process, due to the limitation of the emulsifying ability of the emulsifier, the generated emulsion will be unstable with the change of temperature and time during the placement process, resulting in stratification, which will not be effective in the actual fur leather processing. very good result
Therefore, the fatliquors used today are unstable and cannot be stored for a long time

Embodiment 1

[0023] The preparation method of fatliquor is as follows:

[0024] (A) 100kg of ox hoof oil and 40kg of castor oil were mixed and stirred at 40°C for 20min to obtain the first mixture;

[0025] (B) Add 25kg of phosphorus pentoxide into the first mixture, mix and stir at 65°C for 120min, then raise the temperature to 75°C and stir for 120min to obtain the second mixture;

[0026] (C) Under the condition of cooling the second mixture to 50°C, add 4kg of sodium hydroxide solution with a mass concentration of 20% and 15kg of ethanolamine dropwise in turn, then raise the temperature to 65°C and add 50kg of water at a temperature of 60°C, and stir for 60 minutes Fatliquor is obtained.

Embodiment 2

[0028] The preparation method of fatliquor is as follows:

[0029] (A) 200 kg of natural beef hoof oil with a saponification value of 195 and 200 kg of refined castor oil were mixed and stirred at 45° C. for 30 minutes to obtain the first mixture;

[0030] (B) Add 150 kg of phosphorus pentoxide into the first mixture, mix and stir at 75°C for 140 minutes, then raise the temperature to 90°C and stir for 140 minutes to obtain the second mixture;

[0031] (C) Under the condition that the second mixture is cooled to 65° C., 38 kg of sodium hydroxide solution with a mass concentration of 30% is first added dropwise, and the dropwise addition time is 10 min while stirring while adding, then 100 kg of diethanolamine is added dropwise, and then the temperature is raised to Add 200kg of water at 65°C at 70°C and stir for 80 minutes to obtain the fatliquoring agent.

Embodiment 3

[0033] The preparation method of fatliquor is as follows:

[0034] (A) 150 kg of natural beef hoof oil with a saponification value of 200 and 150 kg of refined castor oil were mixed and stirred at 40° C. for 25 to obtain the first mixture;

[0035] (B) Add 100 kg of phosphorus pentoxide into the first mixture, mix and stir at 65°C for 120 minutes, then raise the temperature to 75°C and stir for 140 minutes to obtain the second mixture;

[0036] (C) Under the condition that the second mixture is cooled to 60° C., first dropwise add 30 kg of a mixed solution of potassium hydroxide and sodium hydroxide with a mass concentration of 25%, and the dropping time is 10 min while stirring while adding, and then dropwise adding three Add 80kg of ethanolamine, add dropwise for 60min while stirring, then raise the temperature to 70°C, add 100kg of water with a temperature of 65°C, and stir for 60min to obtain the fatliquoring agent.

Abstract

The invention relates to the field of fur leather processing, and particularly relates to a fatting agent and a preparation method thereof. The raw material of the fatting agent comprises the following components in parts by weight: 10-200 parts of neats-foot oil, 40-200 parts of castor oil, 25-150 parts of phosphorus pentoxide, 4-38 parts of 20-30wt% inorganic alkali solution, 15-100 parts of organic alkali and 50-200 parts of water. Compared with the fatting agent in the prior art, the fatting agent provided by the invention has high water solubility, good emulsification effect and stable character, and can be stored for a long period of time. The leather has excellent oiliness in surface, soft skin and high cleaning rate after the fatting agent disclosed by the embodiment of the invention is added to the leather, and the whiteness of the skin surface is not deepened.

Description

technical field [0001] The invention relates to the field of fur leather processing, in particular to a fatliquoring agent and a preparation method thereof. Background technique [0002] At present, the fatliquor commonly used in fur leather processing is direct emulsifying fatliquor. The preparation of direct emulsifying fatliquor is to combine oil and water under the action of surfactant to form oil-in-water or water-in-oil state. The advantages of this emulsifying fatliquor are strong oil feeling, smooth skin, and Waxy. [0003] However, in the actual application process, due to the limitation of the emulsifying ability of the emulsifier, the generated emulsion will be unstable with the change of temperature and time during the placement process, resulting in stratification, which will not be effective in the actual fur leather processing. excellent results. Therefore, the fatliquors used today are unstable and cannot be stored for a long time. Contents of the invent...
