以硅烷偶联剂 KH550为改性剂对纳米TiO 2进行改性,制得 KH550改性纳米 TiO 2(KH550-TiO 2),然后以其与氢化蓖麻油为原料,通过原位法制得了改性氢化蓖麻油/KH550改性 TiO 2纳米复合材料(SSF/KH550-TiO 2),再将其应用于山羊皮服装革的加脂工序中。采用 X 射线衍射(XRD)、红外(FT-IR)及热重(TGA)对 KH550-TiO 2进行表征,采用 FT-IR、动态激光散射(DLS)、透射电镜(TEM)和紫外分光光度计(UV)对 SSF/KH550-TiO 2进行表征,并且对应用后革样的耐黄变性能、机械性能、增厚率及柔软度进行检测,同时也通过扫描电子显微镜(SEM)对胶原纤维进行观察。XRD、FT-IR 和 TGA 检测结果表明,硅烷偶联剂能够成功地对纳米 TiO 2进行改性,并且不改变 TiO 2晶型结构,其包覆率在2．27％~2．72％。DLS、UV 和 TEM 检测结果表明,KH550-TiO 2的引入,不仅能够明显降低 SSF/KH550-TiO 2的粒径,也能提高 SSF/KH550-TiO 2的紫外吸收性能,并且 KH550-TiO 2均匀地分散在 SSF/KH550-TiO 2中。革样性能表明,KH550-TiO 2的引入对革样的机械性能影响不明显,但耐黄变、增后率及柔软度明显增加,并随着 KH550-TiO 2引入量的增加而增加。SEM 检测结果表明,KH550-TiO 2能够渗透到胶原纤维之间。

Modified TiO 2 (KH550-TiO 2 )was prepared by γ-ammonia propyl triethoxysilane and TiO 2 .Hydro-genated castor oil and modified titanium synthesizedhydrogenated castor oil/γ-ammonia propyl triethoxysilane modifiedtitanium nanocomposites (SSF/KH550-TiO 2 )by in-situ method.Finally SSF/KH550-TiO 2 was applied in fatliquoring of goatskin garment and properties of the fatliquored leather were tested.KH550-TiO 2 was char-acterized by X-ray diffraction (XRD),fourier transform infrared spectroscopy (FT-IR)and thermogravimetric analysis(TGA).dynamic SSF/KH550-TiO 2 was characterized by FT-IR,dynamic laser scattering(DLS),UV spectrophotometer (UV)and transmission electron microscope (TEM).Mechanical properties,flexibility and anti yellowing properties of the fatliquored leather were tested,meanwhile fibers were observed by scanning e-lectron microscope (SEM).The XRD,TGA and FT-IR results showed that KH550 could successfully modify TiO 2 ,crystal form of modified TiO 2 did not change and KH550 coating rate was 2.27%-2.72% on TiO 2 surface. DLS,UV and TEM results showed emulsion particle diameter SSF/KH550-TiO 2 was obviously decrease and ultraviolet absorption was obviously heighten,after KH550-TiO 2 was introduced.Meanwhile KH550-TiO 2 could evenly distribute in the SSF/KH550-TiO 2 .Crust leather results indicated that anti yellowing,softness and thickening were improved with KH550-TiO 2 increased.However,mechanical propertythe fatliquored leath-er was reduced.SEM results indicated that KH550-TiO 2 cloud enters among collagen fibers.
