中文摘要: |
对锦州石油化工公司生产的3种不同门尼粘度的钱系BR(NdBR)从微观结构到生胶混炼性能、硫化胶静态和动态性能等进行了全面的剖析试验。结果表明,与镍系BR(NiBR)相比,NdBR的平均相对分子质量高,混炼胶强度与挺性明显改善,但挤出工艺稍差;硫化胶拉伸强度、弹性、生热、滚动阻力、动态力学等性能均良好,显示了典型的钱系BR性能特征,NdBR是一种比NiBR更为优良的BR。 |
英文摘要: |
A comprehensive analytical test was made on the micro-structures ,the mixing process,and the static and dynamic properties of vulcanizates for 3 types of NdBRs with different Mooney-viscosity from Jinzhou Petro-Chemical Company.It was found through the test that NdBR showed higher average molecular weight ,improved green strength and stiffness,but somewhat poorer extrudability when compared to NiBR;the tensile strength ,elasticity,heat build-up,rolling resistance and dynamic properties of NdBR vulcanizate were superior to those of NiBR vulcanizate. |
