摘要
用双酚S衍生物与碱式铝盐形成的配合物对山羊酸皮进行鞣制实验,通过测定坯革收缩温度(Ts)和观察粒面状况变化,发现配合物的鞣制效果和铝盐的碱度及其与双酚S衍生物的配比相关。实验中最佳鞣性的配合物组成是n(双酚S衍生物):n(Al3+)=1∶1,铝盐碱度以33%为宜;优选的配合物鞣制的适宜应用工艺主要参数为:配合物鞣剂用量5%,鞣制3 h,其鞣制的坯革Ts达到78℃;将双酚S衍生物、碱式硫酸铝和配合物三者鞣性进行对比,证实了双酚S衍生物与碱式铝盐配体之间形成了一定的配位络合,鞣制性能具有协同效应;通过考察坯革经不同介质处理后收缩温度的变化情况,表明配合物与皮胶原纤维具有良好的键合作用。
The property of Bisphenol S derivatives -AI（ III ）complex tanning agent was studied with the goat pickling pelts tanning application and evaluated the changes of shrinkage temperature and grain of the crust. It was found that the tanning property is related to the alkalinity of aluminum salts and its proportion complexed with the Bisphenol S derivatives. The results indicated that the best alkalinity is 33 %, the best proportion is n （ Bisphenol S derivatives） ： n （ Al3＋ ） = 1 ： 1 ; the optimal application process of the complex is used at the amount of 5 %, tanning 3h and the shrinkable temperature of crust could reach to 78 ℃ after tanning . Comparing to after aluminum tanning and Bisphenol S derivatives tanning, it showed that there is synergy between the Bisphenol S derivatives and alkali aluminum salts in tanning and they could coordinate with each other and the complex tanning agent could combine with the collagen fiber well proved by the changes of shrinkage temperature after dealing with different mediums.
