Synthesis of Modified Hydrogenated Castor oil/ nano-ZnO Composites and its Application as a Fatliquoring Agent

Abstract

Modified hydrogenated castor oil/nano-ZnO composites have been successfully prepared via a facile chemical approach. In this method, ZnO nanoparticles were first modified by isopropyl tri(dioctyl pyrophosphate acyloxy) titanate (NDZ201) to obtain NDZ201 modified ZnO, and then the NDZ201 modified ZnO was introduced into hydrogenated castor oil to prepare modified hydrogenated castor oil/nano-ZnO (MHCO/ZnO) composites. The stability and anti-UV susceptability of MHCO/ZnO composites were investigated. The results show that MHCO/ZnO composites have better UV resistance and stability than hydrogenated castor oil. Both MHCO and ZnO have the anti-UV synergistic effect. MHCO/ZnO composites as fatliquoring agents were applied to leather. The yellowing resistance, softness, and strength properties involving tensile strength, elongation at break and tear strength of fatliquored leather were studied. The tests indicated that the leather fatliquored by MHCO/ZnO composites exhibited an excellent anti-yellowing performance. ZnO nanoparticles had toughening and reinforcing effects for leather. The morphology of fractured surfaces of the selected leather samples and the distribution of Zn element were observed by SEM-EDS. SEM-EDS analysis reveals that ZnO nanoparticles exist on the leather fibres.
