Embodiment 1

[0068] A kind of degreasing agent, each component and content are as follows:

[0069]

[0070] Compound A is an isomeric alcohol block polyether with a structure represented by formula (1), and its HLB value is 10.5.

[0071]

[0072] Compound B is an isomeric alcohol block polyether with the structure shown in formula (2), and its HLB value is 11.5.

[0073]

[0074] Compound C is an isomeric alcohol block polyether with a structure represented by formula (3), and its HLB value is 13.5.

[0075]

[0076] The organic solvent is a mixture of ethylene glycol and ethylene glycol monobutyl ether in a mass ratio of 1:1.

[0077] The fungicide is a mixture of morpholine and benzisothiazolinone at a mass ratio of 1:1.

[0078] The degreasing agent in this example is obtained by uniformly mixing the above-mentioned components according to the proportion.

Embodiment 2

[0080] A kind of degreasing agent, each component and content are as follows:

[0081]

[0082] Compound A, Compound B and Compound C are the same as in Example 1.

[0083] The solvent is a mixture of ethylene glycol and ethylene glycol monobutyl ether in a mass ratio of 1:3.

[0084] The fungicides are morpholine and benzisothiazolinone.

[0085] The degreasing agent in this example is obtained by uniformly mixing the above-mentioned components according to the proportion.

Abstract

The invention discloses a leather degreasing agent, a preparation method and application thereof. A degreasing agent comprising one, two, three or more isomeric alcohol block polyethers selected from the following formula (I): RO[CH 2 CH(CH 3 )O] n (CH 2 CH 2 O) m H (I); Wherein, R is selected from the isomeric alkyl group with an average degree of isomerization ≥ 2; n is selected from the number of 1-8; m is selected from the number of 0.5-15. The degreasing agent has good penetration and emulsifying effect, which can effectively reduce the oil content in the leather embryo; the fatliquoring agent is suitable for the processing and degreasing of cowhide, sheepskin, pigskin and other leather products.

Description

technical field [0001] The invention belongs to the field of leather additives, in particular to a leather degreasing agent and its preparation method and application. Background technique [0002] Leather usually refers to the denatured and non-perishable animal skin obtained through physical and chemical processing such as depilation and tanning. Leather is composed of natural protein fibers tightly woven in three-dimensional space. There is a special grain layer on the surface, which has natural grain and luster, and feels comfortable. The process of processing raw hides and skins into leather mainly includes three stages: preparation, tanning and finishing. Among them, the preparation stage includes processes such as soaking in water, fleshing, liming and depilation, softening and pickling, so that the raw hide is in a state ready for tanning. The tanning stage is the qualitative change stage of transforming raw hide into leather. Through tanning, the structural stabil...
