| 摘要：以秋兰姆为稳定剂的硫醇调节型氯丁橡胶CR2442为主体材料、以间-甲-白-钴体系为粘合体系制备用于海洋环境且与黄铜粘合的胶料，探讨白炭黑用量对CR胶料物理性能和粘合性能的影响。结果表明：随着白炭黑用量增大，胶料的门尼粘度增大，当白炭黑用量达到15份后，门尼粘度增幅显著增大；胶料的硬度增大，拉伸强度减小，海水浸泡后质量变化率增大。当白炭黑用量为15份时，老化前、海水浸泡后和热老化后黄铜丝的抽出力均最大；当白炭黑为20份时，海水浸泡前后黄铜丝的抽出力差值较小。CR胶料的白炭黑适宜用量为15份。 |
| 英文摘要: |
| Using thiol-regulated chloroprene rubber（CR）2442 with thiuram stabilizer as the main material and resorcinol-formaldehyde-silica-cobalt salt system as the adhesive system，the CR compound for the marine environment and bonding with brass was prepared. The effects of silica amount on the physical properties and adhesive properties of the CR compound were discussed. The results showed that，the Mooney viscosity of the CR compound increased with the increasing of silica amount，and increased significantly when silica amount reached 15 phr. The hardness of the CR compound increased with the increasing of silica amount，the tensile strength decreased，and the mass change rate increased after seawater immersion. When silica amount was 15 phr，the pull-out force of brass wire was the largest, even after seawater immersion or thermal aging. When the silica amount was 20 phr，the difference of the pull-out force of brass wire before and after seawater immersion was smaller. The suitable amount of silica for CR compound was 15 phr. |
