Description

发明名称：一种双轴或三轴偏心转子体积脉动形变塑化加工方法及 设备
技术领域
[0001] 本发明涉及高分子材料塑化加工方法与设备， 特别是涉及一种高分子材料双轴
、 三轴偏心转子体积脉动形变塑化加工方法及设备。
背景技术
[0002] 双、 三螺杆挤出加工是高分子材料加工过程中的一种重要方法， 相对于单螺杆 挤出加工， 双、 三螺杆挤出加工具有更好的混合混炼、 反应和排气效果， 适合 于加工热稳定性差的塑料， 特别适合于加工共混料。 双、 三螺杆挤出加工物料 的塑化输送过程主要依赖于螺杆旋转吋对物料的剪切拖曳作用， 因此当前双、 三螺杆加工高分子材料普遍存在热机械历程长、 加工能耗高、 混合混炼效果差 、 设备结构庞大以及对物料依赖性强等缺陷。 为了提高高分子材料的混合、 混 炼效果， 降低高分子材料在塑化输运过程中的能耗， 一些研究者在螺杆的某些 部位增设捏合元件使塑化加工过程中的局部流场受拉伸流变控制， 但是这种局 部流场的控制并未改变物料在双、 三螺杆挤出加工塑化输运过程中受剪切流变 支配的机理。
[0003] 随着当前新型高分子材料如植物纤维增强材料、 可降解材料、 高性能材料等层 出不穷， 同吋对于高分子材料制品的尺寸精度、 混合分散特性、 力学性能等各 项指标的要求也越来越高， 因此对于高分子材料的塑化加工设备也提出了更高 的要求。 基于拉伸流变的叶片聚合物塑化输运方法是通过物料加工体积周期性 变化强制物料熔融塑化和混合混炼， 物料的流动和变形主要受拉伸应力支配， 主速度梯度与其主流动和变形的方向一致， 表现出拉伸流变行为， 从而解决了 螺杆加工机械塑化能力主要依赖物料外摩擦力和内摩擦力的问题。 与螺杆塑化 输运方法相比， 叶片塑化输运方法具有能耗低、 热机械历程短、 对物料适应性 高、 分散混合效果好等优点； 但是在叶片塑化输运过程中， 聚合物输送通道非 流线型， 不利于加工热敏型聚合物的塑化与混合改性。 [0004] 针对目前高分子材料加工行业所存在的问题， 幵发一种能够显著提高高分子材 料的分散混合、 塑化混炼效果， 缩短热机械历程并降低能耗， 有效避免高分子 材料在加工过程热降解的塑化输运新方法和新设备对于高分子材料加工成型领 域具有重要意义。
