Preparation, Characterization of Silicone Succinate Ester and its Application in Leather Industry
The silicone succinate ester surfactant (PMPS) was synthesized by the raw materials of polyether alcohol amine modified polysilosane (PAPS) and maleic anhydride (MA) at 90°C for 4.5h, and p-toluenesulfonic acid (PTSA) was used as the catalyst. Sulfated neatsfoot oil, oxidized-sulfited fish oil was mixed with PMPS to prepare a new leather fatliqour (F-1). The structure of the materials and PMPS were characterized by FTIR. The biodegradability of F-1 was analyzed by BOD5 and CODCr and the tissue slices of the leather samples oiled by PMPS were observed by Multimedia Microscope to study the fatliquoring effect. The waterproof properties and the fatliquored leather were determined. All the results indicated that the F-1 fatliquor has good fatliquoring effect.
