摘要：采用机械共混和胶料成膜工艺制备了一种酚醛 - 橡胶型膜状胶黏剂，探讨了主要组份对胶黏剂胶接性能的影响。该 膜状胶黏剂与制备的底胶构成的双涂层胶接体系满足天然橡胶与金属的热硫化粘接，扯离强度达到 4.0MPa 以上，180°剥离强 度达到 3.0kN/m 以上，且试件大都为橡胶内聚力破坏。热失重（TGA）测定膜状胶黏剂固化产物的明显热失重温度达到了 350℃ 以上，其热稳定好。该胶接体系不仅适用于天然橡胶与金属的热硫化粘接，还适用于天然橡胶与树脂基复合材料的热硫化胶接， 目前该胶接体系已成功应用于天然橡胶与碳 / 聚酰亚胺复合材料胶接构件的制造中。 关键词：天然橡胶；金属；树脂基复合材料；底胶；膜状胶黏剂；双涂层胶接体系 中图分类号：TQ 437.4 文献标识码：A 文章编号：1001- 0017（2010）06- 0018- 04 Study on Double Coating Bond System for NR to Metal Bonding WANG De-zhi, QU Chun-yan and FENG Hao （Institute of Petrochemistry，Heilongjiang Academy of Sciences，Harbin 150040，China） Abstract: A phenolic-rubber film adhesive was prepared by mechanical blending and film technique; the effects of basic compositions on the adhesive bonding strength were discussed. Double coating bond system was composed of the film adhesive and primer which had been developed to meet the requirement of NR to metal bonding，the tear-strength reached 4.0MPa and more，the peel-strength was more than 3.0kN/m and the failure mode of most bond test specimens was rubber cohesive failure. DTA-TG curves of the film adhesive exhibited the thermogravimetric temperature was 350℃ which indicated that the adhesive had good heat-resistance. This bond system had good adhesion not only for NR to metal but also for NR to resin matrix composites and had succeeded in bonding NR to carbon/polyimide composites.
