Abstract

The invention relates to leather finishing emulsified oil and a preparation method thereof. The leather finishing emulsified oil is prepared from the following raw materials: natural oil, an emulsifier, a co-emulsifier and water. The emulsified oil prepared by the invention can effectively improve the pore uniformity and water absorption, has good oily feel and fine moistening feel, has a slight softening effect on crust grain surfaces, does not cause loosening, has sufficient oily feel and strong tenderness, has a moderate grain surface softening effect, has uniform and fine pores and good water absorption uniformity, has good polishing performance, and has sufficient oily light sensation and lasting brightness after lustring.

Description

technical field [0001] The invention belongs to the technical field of leather processing and finishing, and in particular relates to a leather finishing emulsified oil and a preparation method thereof. Background technique [0002] After the raw leather in leather production passes through the preparation section, tanning agent section, and post-tanning wet treatment section, it enters the finishing section. The full-grain napa leather embryo entering the finishing section has a hard grain surface and scattered pores. The problem of poor water absorption uniformity. In order to solve this problem, an oil spray operation is generally added before other coating materials are processed to slightly soften the grain surface, improve the uniformity of pore distribution and water absorption, and at the same time make the grain surface of the leather embryo have a good oily finish. Sensation and delicate moist feeling. The oils used in this process are generally non-ionic emulsif...
