摘　　要：以葛根中药废渣(PRCMR)与废旧聚丙烯(WPP)聚乙烯(WPE)为原料,采用挤塑辊压成型工艺制备WPP/WPE/PRCMR复合材料,利用L16(45)正交试验设计方法对复合材料的力学性能进行了研究,找到最佳的工艺参数以指导生产实践。结果表明,第一段螺杆转速为80r/min,机筒温度为200℃,第二段螺杆转速为40r/min,机筒温度为180℃时,复合材料的冲击强度、静曲强度、弹性模量分别为57.91kJ/m^2、59.95MPa、5.71GPa,复合材料力学性能较好。WPP/WPE/PRCMR composites were prepared by extruding and rolling molding process using Pueraia radix Chinese medicine residue(PRCMR) and waste polypropylene (WPP) and waste polyethylene (WPE) as raw materials.Mechanical properties of composites were studied by using L 16 (4 5) orthogonal experiment design method to find the best process parameters to guide the production practice.The results show that when the first section of the screw rotation speed is 80 r/min,barrel temperature is 200℃,the second section of the screw rotation speed is 40r/min,barrel temperature is 180℃,the impact strength,static music intensity and elastic modulus of composite templates respectively is 57.91kJ/m 2、59.95MPa、5.71 GPa,and the mechanical properties of composites are better.
