摘　　要：以尼龙6(PA6)和热塑性弹性体(TPE)之间的界面粘结强度为研究对象,采用正交试验分析方法,研究注射工艺参数对两种材料界面粘结强度的影响。实验结果表明:塑化温度的影响最大,注射压力次之,而注射速率和保压压力的影响性最小。通过优化注射工艺参数,可提高双物料注射成型试样界面粘结强度。The interfacial adhesive strength between PA6 and TPE was investigated. The influence of process parameters on the interfacial adhesive strength was obtained by adopting orthogonal design. The results showed that plasticizing temperature had the greatest influence on the interfacial adhesive strength, and the influence of injection pressure was secondary, while injection speed and holding pressure had less effect. By optimizing the process conditions parameters,the interfacial adhesive strength of the sample of two-material injection molding was improved.
