| titleOfInvention | Yellowing-resistant high-adhesion leather finishing agent and preparation method thereof |
| abstract | The anti-yellowing high-adhesion leather finishing agent provided by the invention adopts a monomer containing mussel adhesive protein functional units (catechol groups) to prepare a polyacrylate polymer, so that the adhesion performance of a coating can be effectively improved. Substances containing catechol groups in the high-adhesion leather finishing material are easy to yellow under long-time illumination or alkaline conditions. The invention provides a leather finishing agent which comprises an ultraviolet absorbent, wherein nitrogen-nitrogen double bonds in the structure of the ultraviolet absorbent can effectively absorb ultraviolet rays; when the azobenzene structure contains carboxylic acid groups, protons can be removed, and the carboxylic acid groups and benzene rings form a more stable conjugated system, so that the azobenzene structure has better absorption efficiency when being used as an ultraviolet absorbent of the coating; meanwhile, the removed protons can neutralize alkalinity, so that the leather finishing agent is prevented from forming an alkaline environment, and the three conditions can effectively enhance the yellowing resistance of the leather finishing agent. |
