摘要: 利用高剪切分散乳化机将聚α-烯烃中的微量水均匀分散,采用润滑油泡沫特性测定法、石油产品运动黏度测定法、石油产品黏度指数计算法、闪点测定法(宾斯基-马丁闭口杯法)、热重分析法分别评价微量水对高黏度聚α-烯烃理化性能的影响。结果表明:质量分数为0.001 %和0.005 %的微量水可以降低聚α-烯烃的100 ℃运动黏度和黏度指数,能有效改善高黏度聚α-烯烃生成泡沫倾向和降低泡沫稳定性能,而对其闪点(闭口)和热重性质基本没有影响。

Abstract: Trace water was uniformly dispersed into high viscosity Polymer Alpha Olefins (PAO) using high shear dispersing emulsifier. The influence of trace water on the properties of high viscosity PAO was studied by the methods of determination of foaming characteristics, kinematic viscosity and viscosity index, and flash point (Pensky-Martens closed cup method) and TGA. The results show that the trace water of 0.001% and 0.005% can effectively improve the foaming tendency and reduce the foaming stability, 100 ℃ kinematic viscosity and viscosity index. However, no influence on flash point (closed cup) and TGA of high viscosity PAO is observed.
