摘要
简述了原位聚合PVC/CaCO3纳米复合树脂的制备方法与性能,通过毛细管流变仪考察了不同纳米CaCO3用量下PVC纳米树脂剪切速率对剪切黏度的影响,探讨了加工过程中PVC纳米树脂剪切变稀的机制并给出了加工应用实例,展望了PVC纳米树脂的发展前景。结果表明:加工过程中采用PVC纳米树脂可降低设备的能耗,具有很好的发展前景。
The preparation methods and properties of in-situ polymerization PVC/CaCO3 nano- composite resins are introduced. Thc effect of shear rate on shear viscosity of PVC nano-resins with different amount of nano-CaCO3 is investigated with capillary rheomcter. The shcar-thinning mechanism of PVC nano-resins during processing was discussed with application examples. The development prospects of PVC nano-resins arc predictcd. The results show that the application of PVC nano-resins to processing can reduce energy consumption of equipment and exhibits bright prospects.
