| 中文摘要: |
| 从定子管材的表面处理、粘合剂涂刷方式、注胶方式和硫化工艺等方面阐述影响橡胶与定子粘合强度的因素。应根据定子热处理和机加工过程中存在的油污的类别选择合适的金属表面处理方式及清洗剂；粘合工艺的重点是根据配方选择合适的粘合剂、涂刷方式、涂刷厚度和隔绝空气污染；注胶时综合考虑注胶压力、速度、温度及方式，减少胶料对粘合剂的冲刷；硫化时应控制硫化罐内温度、保证压力均匀。 |
| 英文摘要: |
| The factors influencing the adhesion strength between rubber and metal，such as stator surface treatment，application method of adhesive，dispensing process and vulcanization process，were described in this paper.In stator surface treatment，the surface treatment process and cleaning agent should be selected based on the oil contamination type from heat treatment and machining process.The key points of bonding process were to choose suitable adhesive，adhesive application method， adhesive thickness and avoid air contamination.During the dispensing，the pressure，speed，temperature and dispensing method should be taken into account，and it was critical to avoid any damage to adhesive layer.Furthermore，the temperature in the autoclave and uniformity of pressure should be accurately controlled. |
