聚乙烯醇缩丁醛溶液的动态流变性能
Dynamic rheological properties of polyvinyl butyral solution
摘要
Abstract
The effects of temperature, mass fraction of PVB and shearing frequency on the dynamic rheological properties of the polyvinyl butyral (PVB)/polyethylene glycol(PEG200) system were investigated by AR2000 stress controlled rheometer (TA Co., USA). The results show that the complex viscosity, dynamic storage modulus and dynamic loss modulus decrease with the increase of temperature. The complex viscosity, dynamic storage modulus and dynamic loss modulus increase with the increase of mass fraction of PVB. The complex viscosity of PVB solution decreases, while the dynamic storage modulus and dynamic loss modulus increases with the increase of shearing frequency. The loss factor increase first and then decrease with the increase of shearing frequency, the loss peak occurs at shearing frequency 0.6 rad/s, and it decreases with the increase of PVB mass fraction.关键词
