摘要：以乙烯基三甲氧基硅烷（A-171）为原料，水解缩合合成了笼型八乙烯基倍半硅氧烷（POSS-Vi），POSS-Vi
与甲基丙烯酸（MAA）发生自由基聚合，制备了多羧基 P(POSS-MAA)复合材料。采用核磁共振波谱（NMR），
傅里叶变换红外光谱（FTIR），X 射线衍射（XRD）和透射电子显微镜（TEM）对其进行了表征。结果表明，
成功制备了 P(POSS-MAA)复合材料，POSS-Vi 均匀分散于 P(POSS-MAA)复合材料中。将 P(POSS-MAA)复合材
料配合 2%（以山羊皮酸皮质量为基准，下同）铬粉应用于山羊皮酸皮的鞣制工艺，将其作为结合鞣制与 2%铬
粉鞣制进行对比。结果表明，复合材料的引入有利于提高坯革的收缩温度、增厚率、降低废液中 Cr 2 O 3 含量；
当 POSS-Vi 在 P(POSS-MAA)复合材料中含量为 6%（以 MAA 的质量为基准，下同）时，结合鞣鞣制效果最好，
坯革收缩温度（T s ）可达 96.5 ℃，增厚率达 36%；与铬单独鞣制对比，废液中 Cr 2 O 3 质量浓度由 122 mg/L 降低
至 41 mg/L。

Abstract: Octavinyl polyhedral oligomeric silsesquioxane (POSS-Vi) was prepared by hydrolysis and
condensation of vinyl trimethoxysilane (A-171), and then a multi-carboxyl P(POSS-MAA) composite
material was synthesized by the free radical polymerization of POSS-Vi and methacrylic acid (MAA). The
structure of the P(POSS-MAA) composite material was characterized by nuclear magnetic resonance
(NMR), Fourier transform infrared (FTIR) spectroscopy, X-ray diffraction (XRD) and transmission electron
microscope (TEM). The results showed that the P(POSS-MAA) composite material was successfully
obtained, and POSS-Vi was evenly distributed in the P(POSS-MAA) composite material. Subsequently, the
P(POSS-MAA) composite material combined with 2% (based on mass of goat acid skin, as the
below)chromium was applied to the tanning process of goat acid skin. As a result, the introduction of
P(POSS-MAA) composite material could improve the shrinkage temperature and thickening rate of leather
and decrease content of Cr 2O 3 in the waste solution. The P(POSS-MAA) composite material containing 6%
(based on the mass of MAA, as the below) POSS-Vi had the best tanning effect. The shrinkage temperature
(T s) reached 96.5 ℃ and the thickening rate was up to 36%. Compared with chrome tanning process
without addition of P(POSS-MAA) composite material, the mass concentration of Cr 2O 3 in the waste
solution decreased from 122 mg/L to 41 mg/L.
