摘要
以氟硅树脂/漆酚的共混体系为研究对象,重点研究共混体系的流变行为,对不同组分配比的共混体系的流变类型、触变程度、结构恢复速度进行了研究。结果表明:氟硅树脂/漆酚共混体系的n值都小于1,均为假塑性流体;共混体系样品的黏度与剪切时间有关,在恒定的剪切速率80 s-1下,黏度随剪切时间的增加而降低,这表明共混体系也是触变性流体;共混流体有适当的触变程度和结构恢复速度,有利于控制涂膜的外观和性能。
The rheological property of fluorin-silicon resin/urushiol composite system was studied.The rheological behavior,rheologial style,thixotropy and structure-resume velocity of the composite with different proportion were examined.The results indicated that all n values of the composite are less than 1,belonging to a pseudoplastic fluid.The composite also is a thixotropic fluid,its viscosity is related to shearing time,and the viscosity decreased with the increase of shearing time under constant shearing speed of 80 s-1,showing its appropriate thixotropy and structure-resume speed which are beneficial to control the appearance and performance of coatings.
