| 通过对JSR生产的EP33和吉化生产的J-4045生胶、混炼胶和硫化胶进行各项相关性能测试,对这两个牌号的橡胶进行了系统性的评价。 EP33和J-4045门尼粘度、平均分子量和分子量分布相差不大；EP33混炼胶硫化速度略快于J-4045混炼胶,硫化后其弹性扭矩大于J-4045硫化胶,损耗角正切值小于J-4045硫化胶；在应变低于300%时,两种橡胶的强度性能基本一致；在破坏性大应变下,J-4045硫化胶强度性能和耐老化性能要好于EP33硫化胶； EP33硫化胶压缩永久变形性能和回弹性要略优于J-4045硫化胶；从配方设计理论的角度,进行适当的配方和生产调整,国产J-4045完全可以替代JSR的EP33,具有一定的经济优势。 |
| 英文摘要: |
| The rubber performance of JSR EP33 and Jihua J-4045 were compared by conducting experiment of the raw rubber, gross rubber and vulcanized rubber. Both of their Mooney viscosity, average molecular weight and molecular weight distribution had the similar values. The experimental results showed that the EP33 rubber had the shorter curing time, higher elastic torque and smaller tanδ value than that of J-4045 rubber. Furthermore, the tensile strength of the EP33 rubber and J-4045 rubber had the similar value when the strain was lower than 300%. The J-4045 vulcanized-rubber had better performance than the EP33 vulcanized-rubber on the tensile strength and aging process, but they had the converse relationship on the performance of compression permanent deformation and rebound resilience. In conclusion, the domestic J-4045 rubber had the potential alteration of JSR EP33 rubber when the formulating of recipe and process were well optimized. |
