摘要
将TiO2/ZnO超细粉体应用于聚酯(PET)的复合改性,其质量比为1%～5%。研究表明,复合体系为非牛顿假塑性流体,其表观黏度随剪切速率的增大而减小;随着超细粉体含量增大,复合物非牛顿流动指数下降,剪切速率上升,流变性能改善;复合物黏流活化能可达81.5kJ/mol,黏温依赖性随着超细粉体含量的增加而增大。
The TiO2/ZnO ultrafine powder was applied to PET composited modification with the proportion of 1%- 5% to improve the properties of PET. The composite systems are non-Newtonian pseudoplastic fluid, and its apparent viscosity decreases with the shear rate increases. The non-Newtonian index decreases and the shear rate of the composite increases with ultrafine powder content enhanced, and the rheological property behavior is improved. The viscous flow activation energy can reach 81.5 kJ/mol, and the viscosity-temperature dependence increases with ultra fine powder content increasing.
