Abstract

The invention discloses a leather comprehensive fat liquor and a preparation method of the same. Currently, the defects, such as high price, poor stability, layering propensity, high solvent dosage and pungent smell, are common issues for the leather comprehensive fat liquor. In the method, esterification and sulfitation products of high alcohol, modified soybean phospholipid, sulfonated plant oil, animal fat, mineral oil emulsifier and water are mixed evenly at 45-65 DEG C, the pH value is regulated to be 6-8, and the solid content is regulated to be 45-55%, thus, the leather comprehensive fat liquor is obtained. The product of the method is excellent in appearance liquidity, the leather fatted by the fat liquor is excellent in softness and fullness, and the surface of the fatted leather is smooth and moist.

Description

technical field [0001] The invention relates to the technical field of leather chemical industry, in particular to a synthetic leather fatliquoring agent and a preparation method thereof. Background technique [0002] Fatliquor is the most used leather chemical material in tanning production. Fatliquoring is also one of the important processes in the leather processing process. After the leather is treated with fatliquoring, a layer of lubricating oil is wrapped on the surface of the leather fiber, which improves the The relative sliding performance between fibers reduces the friction between leather fibers, so that the leather becomes soft, fold-resistant, plump and elastic. At the same time, through the interaction between the active groups in the fatliquoring agent and the leather fibers, Increase the strength and extensibility of leather, and improve the comprehensive performance of leather. As the leather industry has higher and higher requirements for leather fatliquo...
