Greasing agent for improving strength of leather and preparation method thereof

Abstract

The invention provides a greasing agent for improving strength of leather and a preparation method thereof. The greasing agent comprises the following components in part by weight: 0 to 100 parts of polyoxyethylene alkyl phosphate, 150 to 200 parts of fish oil amide, 50 to 100 parts of chlorinated paraffin, 1 to 5 parts of sodium carboxymethylcellulose, 40 to 150 parts of alkyl sodium sulfonate, 0 to 500 parts of olive oil polyethylene glycol ester and 0 to 450 parts of No.30 engine oil. The greasing agent has the advantage of obviously improving the strength of the leather, namely the tear resistance of the leather so that the leather after greasing treatment has smoothness and softness, strong silk feeling, stable quality, low cost and good permeability, absorption and absorption amount.

Description

technical field

[0001] The invention relates to a fatliquoring agent for leather strength and its preparation. technical background

[0002] With the development of leather technology level, the strength of leather, that is, the tear resistance has become an important index to measure the quality of leather.

[0003] In the process of processing natural animal skin into leather, the high-grade leather fatliquoring agent should have the softness and toughness of the leather, the fullness and elasticity of the leather, the smoothness of silk fabric, and not dry and hard with the change of climate and time. performance.

[0004] Chinese patent application No. 88106317 discloses the preparation of fatty acid amido sodium carboxylate composite leather fatliquoring agent, which is mainly composed of fatty acid amido sodium carboxylate compounded with sulfated lard, chlorinated paraffin, ammonium alkylsulfonate Composition, the patent claims that the composite fatliquoring agent ...
