摘要:
以异丙醇铝(AIP)为原料, 异丙醇为溶剂, 硝酸为胶溶剂, 聚乙烯吡咯烷酮(PVP)为表面活性剂, 采用溶胶-凝胶法制备铝溶胶. 利用正交试验方法研究了水解温度, 水与醇盐摩尔比, 硝酸加入量以及分散剂用量对铝溶胶稳定性的影响.结果表明在水解温度为90 ℃,水与异丙醇铝的摩尔比为200, 硝酸与异丙醇铝的摩尔比为4, PVP的用量为异丙醇铝的1‰时是制备铝溶胶的最佳试验条件.对于溶胶稳定性的影响,以水解温度最为显著,硝酸的用量则直接到影响溶液的pH值,还对溶胶的粒径有影响,水量的多少则关系到溶胶的黏度,而分散剂在整个反应过程中起到加快反应速度和防止胶团化的作用.
Abstract:
The aluminum sol was prepared using aluminum isopropoxide(AIP) as raw materials, isopropyl alcohol as solvent, nitric acid as peptizing and Polyvinylpyrrolidone as surfactants by solgel method. The orthogonal test was introduced to study the effects of hydrolysis temperature, the proportion between AIP and H2O, nitric contend, dispersant contend on the sol. The results show that the best preparation conditions for aluminum sol are the ration of aluminum isopropoxide to water of 200, hydrolysis temperature of 90 ℃, the molar ratio of nitrate to aluminum isopropoxide of 4 and the amount of PVP in the aluminum isopropoxide of 1‰. The hydrolysis temperature play an important role in the stability of the sol , the amount of nitric affects directly the pH ,which further influences the particle size of sol, the amount of water contributes to the sol viscosity while the dispersant makes a difference in accelerating the reaction and preventing the solMicelle.
