Problems solved by technology

However, due to the weak oil permeability, most of the oil fails to penetrate to the surface of collagen fibrils (diameter 100nm), but only deposits in the gaps of collagen fiber bundles. In the process of using oil to change the softness of leather, the amount is relatively large. It is far beyond the theoretical value, resulting in great waste; moreover, more oil is filled in the fiber voids, which will lead to a decrease in the porosity and air permeability of the leather, and damage the hygienic performance of the leather
[0004] In addition, this kind of oil pollutes the environment more seriously during the processing process, and it is difficult to adapt to the current low-pollution, high-environmental environment, and faces many challenges

preparation example Construction

[0082] The present invention also provides a kind of preparation method of leather lubricant, such as figure 1 shown, including the following steps:

[0083] A. surfactant is weighed by parts;

[0084] B. Weigh animal fat and lactic acid ester respectively according to the set number of parts;

[0085] C. respectively adding the tallow and lactic acid ester weighed in the B step into the surfactant and mixing and dissolving with the surfactant;

[0086] D. in the mixture of C step, add the organic base that weighs to adjust the pH value of the mixture that step C obtains and the mixed material that organic base forms;

[0087] E. Add the water that weighs in the mixed material that D step has adjusted pH value, mix;

[0088] F. Add the organosilicon material weighed to the mixed material obtained in the E step, and mix;

[0089] G. add the organic acid that takes by weighing in the mixed material that F step obtains to adjust pH value;

[0090] H. Shearing the mixed mater...

specific Embodiment 1

[0126] Weigh 20 parts of Span-60 surfactant, 55 parts of isotridecyl alcohol (6EO) according to the proportion, put them in the reaction kettle, start stirring, raise the temperature to 50°C, add 90 parts of white oil, tallow 45 parts of oil and 40 parts of dodecyl were weighed and added to the reaction kettle in sequence. After all the materials were completely dissolved and uniform, 3 parts of triethanolamine were added to adjust the pH value of the material to 7.5, and the stirring was continued for 30 minutes, and then water 150 95 parts of the anionic hydroxy silicone oil emulsion was put into the reaction kettle, and the temperature was controlled at 50°C and stirred for 60 minutes, and the pH value of the product was adjusted to 7.0 with 2 parts of lactic acid, and the temperature was lowered to 35°C, with 15000 rpm high-speed shearing, start discharging.

specific Embodiment 2

[0127] Weigh 25 parts of Span-80, 45 parts of isotridecyl alcohol (9EO) and 10 parts of Pingjiao-910 according to the proportion and put them in the reaction kettle, start stirring, raise the temperature to 50°C, and put the naphthene 100 parts of oil, 50 parts of hoof oil, and 60 parts of lauryl lactate were weighed and added to the reaction kettle in turn. After all the materials were completely dissolved and uniform, 5 parts of hydroxyethylenediamine were added to adjust the pH value of the materials. 7.5, keep stirring for 30 minutes, then slowly put 140 parts of water into the reaction kettle, after stirring well, put 90 parts of non-ionic amino silicone oil emulsion into the reaction kettle, control the temperature at 50°C and stir for 60 minutes, then use glycolic acid 3 Adjust the pH value of the product to 7.0, stir for 30 minutes, then cool down to 35°C, and start discharging after high-speed shearing at 15,000 rpm.

Abstract

The invention relates to the field of leather, and particularly relates to a leather care agent as well as a preparation method and a preparation device thereof. The leather care agent is prepared from the following raw materials in parts by weight: 10-100 parts of lactate, 1-100 parts of animal oil, 5-100 parts of surfactant, 5-200 parts of organosilicone material, 1-10 parts of organic base, 1-5 parts of organic acid and 1-250 parts of water through mixing. According to the leather care agent as well as the preparation method and the preparation device thereof, provided by the invention, the penetrability of the care agent can be improved.

Description

technical field [0001] The invention relates to the field of leather, in particular to a leather lubricant, a preparation method and a preparation device for the leather lubricant. Background technique [0002] At present, fur products are widely used. In the production of fur products, it is necessary to process the fur to provide fur properties. For example, add oily oily substances, and the oily agent can be added in multiple processes of tanning. The main function is to improve the hand feeling and softness, and help to absorb other tanning additives. It is an important additive for the preparation of soft leather, high-grade upper leather and cowhide split film leather. [0003] The most basic purpose of fur fatliquoring is to distribute the effective components in the fatliquoring agent on the surface of collagen fibers, isolate, disperse and lubricate collagen fibers, prevent them from sticking and hardening after drying, and maintain softness. However, due to the we...
