| 摘 要： | 本工作采用电子显微镜(EM)、大角度X射线衍射(WAXD)、热失重分析(TGA)、动态力学测定等方法,研究了几种典型油品的充油Ln-BR的形态结构和结晶动力学,发现减压渣油(9号油)分子量较高,与Ln-BR的相容性较差,且与硫化后的Ln-BR间可能有少量的化学联结。它的存在明显地促进了Ln-BR的应力诱导结晶(SIC)。这些因素均导致这种充油硫化胶有较高的抗撕裂强度。

| Abstract: | The morphological structure and crystallization kinetics of some oil-extended polybu-tadiene rubber polymerized with lanthanide catalyst were studied with EM, WAXD, TGA and dynamic mechanical measurement. It has been found that No. 9 oil has higher molecular weight than the rest; its compatibility with rubber is much lower; some kind of chemical linkages may exist between oil and rubber when vulcanized; and the No. 9 oil-extended rubber shows stress induced crystallization. These all contribute to the higher tearing stre-ngth possessed by the No.9 oil-extenede polybutadiene rubber. |
