Abstract

The present invention belongs to the field of leather chemical technology. The composite leather greasing agent is prepared with polyoxyethylene alkyl phosphate, cottonseed oil amide, chlorinated paraffin, octyl phenol polyethenoxy ether, sodium alkylsulfate, olive oil glycolate and No. 30 engine oil. The preparation process includes mixing, heating and other steps. The composite leather greasing agent makes leather soft, tough, plumpy, elastic, waterproof, silky, good in stuffing performance, stable in quality and infrared and ultraviolet resistant, and has low cost. The composite leather greasing agent is suitable for cow skin, sheep skin and pig skin.

Description

(1) Technical field [0001] The invention relates to a novel composite leather fatliquor suitable for fatliquoring cowhide, sheepskin and pigskin, which belongs to the technical field of leather chemical industry. (2) Background technology [0002] In the process of processing natural animal skin into leather, the high-grade leather fatliquoring agent should have the properties of making the leather soft and tough, plump and elastic, with the smoothness of silk fabric, waterproof, resistant to infrared and ultraviolet light, and The performance of drying and hardening due to changes in climate and time. In addition, the leather fatliquoring agent itself should also have the properties of being easily absorbed by the leather, less residual liquid in the waste liquid after fatliquoring the leather, and good biodegradability. Therefore, a kind of composite leather fatliquor formulation having above various properties concurrently has been subjected to the attention both at home...
