摘　　要：采用正交试验法,探究注塑工艺中前处理工艺、料筒温度、注塑压力与速度、保压时间和背压对PP/PE-T20材料零件气味和总挥发性有机物(TVOC)的影响,并采用极差分析,确定最佳工艺条件。研究表明,影响零件气味的3个重要因素依次为干燥温度/时间、料筒温度、保压时间,最佳工艺条件为100℃/6 h干燥,料筒温度为200℃,保压时间为15 s;影响零件TVOC的3个重要因素依次为干燥温度/时间、保压时间、背压,最佳工艺条件为100℃/8 h干燥,保压时间为15 s,背压为5 MPa。Orthogonal experiment method is used to explore the influence of injection mold⁃ing process on the drying temperature/time of particles,injection molding process parameters,cylin⁃der temperature,injection molding pressure/speed,holding time and back pressure on the odor and TVOC of PP/PE-T20 material parts,and range analysis is used to determine the best process condi⁃tions.The research shows that the three important factors affecting the smell of parts are drying tem⁃perature/time,barrel temperature and pressure holding time successively.The best technological con⁃dition is 100℃/6 h drying,barrel temperature is 200℃,and pressure holding time is 15 seconds.Three important factors affecting TVOC components are drying temperature/time,holding time,and back pressure in turn.The optimal process condition is drying at 100℃/8 h,holding time is 15 sec⁃onds,and back pressure is 5 MPa.
