一种新型水溶性增粘剂的研究

Study on a New Type Water-Soluble Tackifer

本文介绍了一种新型的水溶性增粘剂———聚炳烯腈钠盐 ,对这种增粘剂在不同浓度和温度下的粘度变化情况进行了研究 ,添加量在 2 0wt%左右时基本能达到水基润滑液的粘度要求 ,粘度指数VI=4 0 0 ;在泵 -喷嘴剪切试验装置上进行剪切试验 ,一段时间后 ,溶液粘度下降很慢 ,完成了充分剪切 。

This paper introduce a new type of water-soluble tackifier and studies the changes of viscosity under the different concentrations and temperatures.When the concentration of the tackifier becomes 20%,its viscosity can meet the needs of water-based lubricant and its VI=400.Through a pump-nozzle shearing experiment the viscosity becomes stable after a period of time.It shows that the solution is provided with a high shearing-stability.
