摘　　要：共进行了两轮DOE实验设计和数据分析。第一轮采用三因子全因子试验,确定了熔胶温度和熔胶时间为关键因素,固化时间为非关键因素,通过对熔胶温度和熔胶时间的响应优化,发现最优点落在条件边界点上,条件边界选择有问题,需要进行调整;第二轮实验采用双因子响应曲面设计,固定固化时间,寻找熔胶温度和熔胶时间的最佳工艺窗口。通过两轮的DOE实验设计,找出了我司蓄电池专用阻燃ABS与竞品达到高焊接强度时,各自对应的优化条件范围,并对各自的优化条件进行了对比,发现竞品相对我司材料来说,想要获得同样的焊接强度时,具有更短的熔胶时间,更宽的加工窗口。Two rounds of DOE experimental design and data analysis were carried out.In the first round,the three factor full factor test was used to determine the melt temperature and melt time as the key factors,and the curing time as the non-key factors.Through the response optimization of melt temperature and melt time,it was found that the best advantage fell on the conditional boundary point,and there were problems in the selection of conditional boundary,which needed to be adjusted.In the second experiment,a two-factor response surface design was used with certain curing time and find the best process window of melt temperature and melt time.Through two rounds of DOE experiment design,we found out the corresponding range of optimization conditions when our company's flame-retardant ABS for batteries and competing products reached high welding strength,and compared the respective optimization conditions,it was found that the competing products had shorter melting time and wider processing window when obtained the same welding strength as our company's materials.
