气相二氧化硅改性不饱和聚酯树脂触变性能的研究

The Study on Thixotropic Properties of Unsaturated Polyester Resin Modified by Fumed Silica

系统研究了不饱和聚酯树脂触变性能的影响因素,通过对气相二氧化硅的添加量、乙二醇助剂等因素的分析,确定了最佳的实验方案,并最终制备了高触变系数和储存稳定性的不饱和聚酯树脂。

In this paper, the influencing factors on the thixotropy of unsaturated polyester resin were systematically studied. The optimum experimental scheme was determined by the analysis of the factors such as the addition of fumed silica and the ethylene glycol additive. The high degree of thixotropy and storage stability of the unsaturated polyester resin was prepared.
