摘要
制备氯化丁基橡胶(CIIR)硫化胶,研究树脂、填料和纤维对CIIR硫化胶阻尼与力学性能的影响,并探讨其阻尼机理。运用动态力学分析仪、扫描电子显微镜、红外光谱仪及拉伸试验对其性能进行测试及表征。结果表明,随着石油树脂与酚醛树脂用量的增大,CIIR硫化胶的玻璃化转变温度疋向高温区域移动,但最大损耗因子tanδmax与树脂种类有关,添加石油树脂tanδmax可达到1.2以上;炭黑改善硫化胶力学性能,粒径较大的炭黑有利于阻尼性能;纤维的尺寸对材料阻尼和力学性能影响明显,其添加量在5~10份为宜:
The high-damping CIIR blends with wide-temperature range were prepared in the presence of resins, fillers and fibers. The damping and mechanical properties of CIIR blends were studied and the mechanism of the damping was investigated. The performances were characterized with DMA, SEM, FTIR and tensile test. The results showed that glass transition temperature ( Tg ) of CIIR blends increased when the contents of petroleum and phenolic resins in- creased with the value of maximal loss factor( tanδmax )much depended on the kinds of resin,tarδmaxOf blends containing petroleum resin reached more than 1.2 ; Carbon black improved the mechanical properties of CIIR blends and that with bigger diameter was better for the damping properties;The fiber length affected the damping properties markedly and its optimum amount was 5 - 10 phr.
