摘　　要：通过浸胶时间与附胶率及H抽出力关系的分析得到:涤纶帘子线的最佳预浸胶时间120s,最佳RFL浸胶时间180s。进而采用正交试验对涤纶帘子线二次浸胶工艺进行研究。结果表明,各因素对帘子线/橡胶粘合性能的影响大小顺序为:解封温度>定型温度>定型时间>解封时间>w(环氧)∶w(水)(质量比)。同时方差分析显示,解封温度、定型温度及定型时间对试验结果有显著影响。SEM结果显示二次浸胶处理后胶液明显附着在了帘子线表面,H抽出表明为典型的内聚破坏。In this paper, the best pre-dipping time is found to be 120 s and the best RFL dipping time is 180 s based on the analysis of the relationship between dipping time and H-extraction force. Then, the two-step process for dipping PET cords is studied via the orthogonal test. The influence of technological parameters on the final adhesive performance is listed in descending order as follows= deblocking tempera- ture）heat setting temperature）heat setting time~〉deblocking time^zv （epoxy） ~ w （water） （mass ratio）. Meanwhile, variance analysis demonstrated that the deblocking temperature, heat setting temperature, and heat setting time had remarkable effects on adhesive properties. SEM images show that the glue ad- hered firmly to the surface of the PET after the two-step treatment, and the fracture during H-extraction can be attributed to typical cohesive failure.
