Problems solved by technology

However, due to the increasing requirements for the light resistance of leather, natural fish oil contains more unsaturated bonds, is easy to oxidize and discolor, and has a fishy smell, so the application range of fish oil fatliquor is limited.

Abstract

The invention provides a fish oil fatliquoring agent and a preparation method thereof. The fish oil fatliquoring agent of the present invention is composed of higher carbon alcohol, maleic anhydride, fish oil, antioxidant, mineral oil, sulfonating agent, compound emulsifier and preservative. The fish oil fatliquoring agent of the invention can not only improve the light resistance and fullness of leather and obtain a satisfactory fatliquoring effect, but also greatly extend the application range of the fatliquor because the fish oil fatliquoring agent has a light fishy taste. The preparation method of the fish oil fatliquoring agent is relatively simple, the requirements for equipment are not high, and the production cycle is short.

Description

technical field [0001] The present invention relates to a kind of fatliquoring agent and its preparation method, more specifically, the present invention relates to a kind of fish oil fatliquoring agent and its preparation method. Background technique [0002] Fatliquor is the most used chemical material in leather production, and it is also one of the important chemical materials in leather processing. It can not only lubricate the leather fiber, prevent the leather from becoming stiff and cracking, but also make the leather have corresponding toughness and softness, and maintain its strength. At the same time, it plays a certain filling role, making the leather plump and elastic. One of the important factors affecting the quality and performance of leather. In the study of fatliquor, fatty alcohol phosphate, fatty acid higher alcohol ester, hoof oil, lanolin, natural phospholipid, fish oil, synthetic macromolecular polyphosphate, etc. all have good filling properties.
