| 本文对泰国北部20号标准胶 1#、泰国南部20号标准胶2#、马来西亚20号标准胶SMR 20和缅甸20号标准胶MSR20进行了研究。通过研究表明：在组成成分上,生胶SMR 20和2#除了含有顺式聚异戊二烯外,还含有少量的3,4结构单元。并且SMR20蛋白质的含量最高,抗热氧老化能力最强。在加工性方面,SMR20的加工性最好,凝胶含量最低,1#的加工性最差。在力学性能方面,SMR20 与1#定伸应力、拉伸强度、耐磨性优于MSR20,但抗撕裂性能比MSR20差。DMA测试结果表明SMR20抗湿滑性最好,滚动阻力小,动态力学性能最优。 |
| 英文摘要: |
| In this paper, in northern Thailand on the 20th standard rubber STR20 BD4, in southern Thailand on the 20th standard rubber STR20 BD2, Malaysia on the 20th standard rubber SMR 20 and Myanmar on the 20th standard rubber MSR 20 were studied.The results showed that In the composition, the raw rubber SMR 20 and STR20 BD2 addition to containing cis-polyisoprene, also contain small amounts of 3,4 structural units. The content of protein of the raw rubber SMR20 was the highest, and its antioxidant ability was the best; In terms of processability,SMR 20 has the best processability and the lowest gel content ,but STR20 BD4 has the worst processability. In the mechanical properties, SMR20 and STR20 BD4 tensile stress, tensile strength, wear resistance is better than MSR20, but the tear resistance is poor than MSR20. DMA test showed that SMR20 had the best moisture resistance, low rolling resistance and excellent dynamic mechanical properties. |
