Abstract

The invention discloses a composite finishing agent used for leather care, and a preparation method thereof, and relates to the technical field of leather care. The composite finishing agent is prepared from, by weight, 10-15 parts of Vaseline, 10-15 parts of modified rapeseed oil, 3-6 parts of pentaerythritol ester of hydogenated rosin, 2-4 parts of C5 hydrogenated petroleum resin, 2-4 parts of a wax assistant, 1-2 parts of glycidyl methacrylate, 1-2 parts of crospovidone, 0.5-1 part of hexamethoxymethylmelamine, 0.5-1 parts of powdery nitrile butadiene rubber, 0.5-1 part of polymeric aluminum chloride, 0.3-0.5 parts of trimethylolpropane triacrylate and 0.3-0.5 parts of sodium bicarbonate powder. The finishing agent is suitable for leather care, and cared leather has soft and smooth hand feeling, bright, smooth and clean appearance and effectively prolonged service life.

Description

[0001] Technical field: [0002] The invention relates to the technical field of leather maintenance, in particular to a composite finishing agent for leather maintenance and a preparation method thereof. [0003] Background technique: [0004] Leather finishing agent is a general term for a class of leather auxiliary agents used to protect and beautify leather on leather surfaces. The basis of the agent. Leather finishing agents also play a very important role in the leather manufacturing industry, which can increase the appearance of leather, prolong the service life of leather, significantly improve the quality and grade of leather products, and increase trade value. Leather is loved for its water and stain resistance and good looks, but over time it develops cracks, scuffs and scratches and requires regular maintenance. But most of the finishing agents used at present can only form a protective film on the leather surface, and cannot penetrate into the leather to improve ...
