Abstract

The invention discloses a high-stability palm oil leather fatliquoring agent, which is composed of the following raw material components in parts by weight: 40-55 parts of modified palm oil, 20-30 parts of beeswax liquid, isotridecanol nutmeg 15~25 parts of acid ester, 2~4 parts of cocoic acid diethanolamide, 2~4 parts of maleic modified rosin, 1~2 parts of isobutanol, 60~70 parts of water. The invention simultaneously discloses a preparation method of a high-stability palm oil leather fatliquoring agent. The fatliquoring agent of the present invention has good emulsifying power, excellent permeability, and excellent stability, can penetrate into the leather plate evenly and deeply, has a strong ability to disperse natural oil, and the fur after fatliquoring is extensible, soft and elastic. Good; the fatliquoring agent has good alkali resistance and water stability, which can meet the extremely high requirements of multi-process step-by-step fatliquoring on the performance of the fatliquoring agent; the use of palm oil with the largest usage, low cost and environmental protection has good The economical and applicable value is conducive to expanding the direction of comprehensive utilization of palm oil.

Description

technical field [0001] The invention relates to the technical field of leather fatliquor and its preparation, in particular to a high-stability palm oil leather fatliquor and a preparation method thereof. Background technique [0002] Fatliquoring is an important process in the production and processing of leather from raw hide to finished leather. It is to apply oil directly or in the form of emulsion to the processed leather under certain conditions, so that the lubricating oil components can penetrate into the leather. Between the leather fibers, the mobility between the leather fibers is increased, making the leather soft and resistant to folding, and at the same time avoiding the defects of the leather surface being stiff and easy to break due to the bonding of the leather fibers. The fatliquored leather has good hand feeling and physical and mechanical properties, while reducing the shrinkage of the leather surface and increasing the finished leather area. [0003] Le...
