Abstract

The invention discloses a leather finishing agent and a preparation method thereof and relates to the technical field of leather. The leather finishing agent is mainly prepared from isocyanate, dibutyltin dilaurate, epoxy resin, triphenyl bismuth, 2,2-dimethylolpropionic acid, lauryl sodium sulfate, polyethylene glycol, triethanolamine N-Coco acy-L-Glutamate, sodium borate, ascorbyl palmitate, cetyl trimethylammonium bromide, dimethicone, Lubrajel, glycerin, lignite wax and a deodorant. The leather finishing agent is high in scratch resistance, has glossy, soft and natural coatings, is good in binding force, very good in stability and good in film-forming property and has very good aging resistance, cold resistance and breathability; besides, the deodorant is prepared from multiple raw materials including triphenyl phosphite, phenoxyethyl isobutyrate, sodium diethylhexyl sulfosuccinate and the like, can effectively remove odors of leather and keep the aroma of leather products, has certain anti-corrosion and antibacterial effects and can improve the quality of leather.

Description

technical field [0001] The invention relates to the technical field of leather, in particular to a leather finishing agent and a preparation method thereof. Background technique [0002] Finishing is a finishing process of resting the leather surface with certain chemicals. The purpose is to make the leather surface shiny and moist, uniform in color, and to decorate the defects of the leather. At the same time, a protective film is formed on the leather surface to improve the waterproof and wear-resistant properties of the leather. . The chemicals that modify leather are called leather finishes. [0003] Existing leather finishing agents have poor weather resistance and poor air permeability after film formation. With the improvement of people's requirements, they cannot meet people's needs gradually. Contents of the invention [0004] The purpose of the present invention is to provide a leather finishing agent and a preparation method thereof in order to remedy the defi...
