| 中文摘要: |
| 研究填料种类、用量及并用比对橡胶悬置元件性能的影响。随着炭黑粒径的增大，胶料的门尼粘度和交联密度减小，硫化胶的耐老化性能提高，动静刚度比减小；随着炭黑N550用量的增大，硫化胶的硬度、定伸应力和撕裂强度提高，动静刚度比增大；随着白炭黑用量的增大，炭黑N774与白炭黑并用填充硫化胶的拉伸强度无明显变化，动静刚度比显著增大；在相同硬度下，纯白炭黑填充硫化胶的动静刚度比小于炭黑N774与白炭黑并用填充硫化胶。 |
| 英文摘要: |
| Effects of filler type，amount and blending ratio on the performance of rubber suspension components were studied.As the particle size of carbon black increased，the Mooney viscosity and crosslinking density of the compound decreased，the aging resistance of the vulcanizate was improved and the dynamic and static stiffness ratio decreased.As the amount of carbon black N550 increased，the hardness，tensile stress and tear strength of the vulcanizate were improved，the dynamic and static stiffness ratio increased.With the increase of the amount of silica，there was no significant change in the tensile strength of the vulcanizate of carbon black N774 blend with silica，but the dynamic and static stiffness ratio significantly increased.At the same hardness，the dynamic and static stiffness ratio of silica filled vulcanizate was smaller than that of carbon black N774 and silica filled vulcanizate. |
