制备纳米/聚合物复合材料时工艺参数的研究

Research of process parameters in the preparation of nano/polymer compound materials

用正交试验法对纳米粉体在聚合物中分散时的工艺参数——主机螺杆转速、加料螺杆转速(加料量)、机筒及机头温度、机头压力对混合效果的影响进行了研究。研究结果表明:影响HDPE/EVA/Nano-Mg(OH)2混合物力学性能的工艺条件的主次顺序为主机螺杆转速、加料螺杆转速、机头压力、机筒及机头温度。

By using orthogonal test, analyzed the influence of mixing effects on the process parameters of nano-powder in the polymer dispersion, such as host screw speed, feeding screw speed （charging volume）, barrel and head temperature and head pressure. The results showed that： the impact factors of mechanical properties of HDPE / EVA / Nano-Mg （OH） 2 compound ordered as the host screw speed, feeding screw speed, head pressure, barrel and head temperature.
