研究 NR1155天然橡胶在不同硫化压力下热硫化后的物理力学性能。基于90°粘合剥离强度测试方法分别测量了不同硫化压力下制备的橡胶／金属复合结构试样的粘合剥离强度，并采用低场 NMR 橡胶交联密度测定仪分析试样中橡胶部分的交联密度，同时采用冷场发射电子扫描显微镜（SEM）研究剥离破坏表面。结果表明：NR1155天然橡胶胶料与 Chemlok205／Chemlok220热硫化胶粘体系具有很好的相容性和协同硫化作用。随着硫化压力的提高，橡胶／金属的粘合剥离强度呈现先降低后增加的规律，且最大剥离力呈现对硫化压力的函数依赖关系，而硫化胶的交联密度则呈现相反的趋势。
The physical and mechanical properties of nature rubber compound vulcanized (NR1 155 )under different curing pressures were studied,such as 6MPa,8MPa,9MPa,10MPa,1 1 MPa,12MPa.The peel strength of adhesive joint in metal /rubber composite structures,vulcanized under different curing pressures,were tested based on standard test methods of the adhesion between vulcanized rubber and rigid substrates.Meanwhile,the cross densities of rubber part in metal /rubber composite structure were studied by rubber cross-linking density measuring instrument (Low-dimensional NMR).Also,the topography of peeled surfaces was investigated by SEM.The results indicate that NR1 155 and chemlok 205 /chemlok 220 adhesive present excellent compatibility and well co-curing syn-ergy effect.In addition,the peel strength of adhesive joint firstly increased and then decreased with the increasing of curing pressure, as well as that largest peel force (F)present well functional dependency to curing pressures,but the cross densities of vulcanized rub-ber present opposite trend.
