摘要
通过互穿聚合物网络技术成功制备了天然橡胶/公共网络/废胶粉共轭三组分,并测定了力学性能和微观形态。结果表明:当A/B摩尔比为2/1、AB含量为4.5%、废胶粉粒径为60目、废胶粉含量为15%时,体系的力学性能最好,共轭三组分天然橡胶/公共网络/废胶粉体系的磨耗体积明显低于两组分天然橡胶/废胶粉体系的磨耗体积。界面共轭互穿改善了界面结合,可减少反复压缩过程中的相间摩擦生热和变形。
The natural mbber/public network/scrap rubber powder conjugated three-component interpenetrating polymer network was prepared through interpenetrating polymer network technology, and determined the mechanical performance and the microscopic shape. Results indicated that the mechanical performance for system was best when the A/B mole ratio was 2/1 with the AB content of 4.5%, the particle size of 60 item for scrap rubber powder, the content of 15% for scrap rubber powder, the abrasion volume of conjugated three-component natural rubber/public network/scrap rubber powder system was clearly lower than that of two-component natural rubber/scrap rubber powder system. The interface conjugated inte.rpenetration improved the interface union, which might reduce the interphase friction-generated heat and distortion in the repeated process.
