1　前言在某型火箭发动机零部件的制作中 ,需要在一个橡胶圆柱部件的外表面粘接一个高 12 0ｍｍ、厚3ｍｍ的环型聚醚聚氨酯内衬。要求橡胶与内衬粘接致密、无脱粘 ;内衬内部和表面都不允许有气泡、凹陷、缺料等缺陷存在。我们选择了一步法操作工艺 ,即直接将聚醚胶、甲苯二异氰 1 Introduction In a rocket engine parts production, the need to adhere to the outer surface of a rubber cylinder components a high 12 0mm, thickness 3mm ring polyether polyurethane liner. Require rubber and lining adhesion dense, no debonding; lined interior and surface are not allowed to have bubbles, depression, lack of material and other defects exist. We chose a one-step method of operation, that is directly polyether rubber, toluene diisocyanate
