摘　　要：研究环氧化天然橡胶(ENR)和偶联剂Si69对芳纶帘线与天然橡胶(NR)粘合性能的影响。结果表明:随着ENR用量的增大,NR胶料的门尼焦烧时间缩短,硫化胶的硬度、拉断伸长率和撕裂强度增大,100%定伸应力和H抽出力先增大后减小,当ENR用量为10份时,NR胶料的综合性能最佳;在间-甲-白粘合体系中,加入偶联剂Si69的NR胶料门尼粘度减小,门尼焦烧时间延长,硫化胶的硬度和定伸应力增大,H抽出力减小,而加入ENR的NR胶料门尼粘度增大,门尼焦烧时间缩短,硫化胶的300%定伸应力减小,H抽出力增大。The effect of ENR and coupling agent Si69 on the adhesion property between aramid fibre and NR was investigated. The results showed that, as the addition level of ENR increased, the Mooney scorch time of NR compound was shortened,the hardness, elongation at break and tear strength of the vulcanizates increased,and the modulus at 100% elongation and the pull-out force of aramid fiber increased at first and then decreased. When the addition level of ENR was 10 phr,the best overall per- formance of NR compound was obtained. With resorcinol-formaldehyde-silica adhesion system, by adding coupling agent Si69,the Mooney viscosity of NR compound decreased,the Mooney scorch time was extended, the hardness and modulus increased, and the pull-out force decreased. However, by adding ENR, the Mooney viscosity of NR compound increased, the Mooney scorch time was shortened, the modulus at 300 % elongation of the vulcanizates decreased,and the pull-out force increased.
