摘　　要：研究5个橡胶树品系天然胶乳的季节性干胶含量和天然橡胶(NR)的理化性质、贮存性能、硫化特性、物理性能。结果表明:各橡胶树品系胶乳的干胶含量随季节变化明显,其中GT1胶乳的平均干胶含量最大,且胶乳的干胶含量随季节波动最小;云研77-4和云研77-2 NR的贮存性能较好;GT1 NR的t90最短,RRIM600和云研77-4 NR的t90较长;GT1和PRI107 NR的物理性能较好。The seasonal dry rubber content of natural rubber latex of five rubber tree strains and the physicochemical characters,storage performances,vulcanization characteristics and physical properties of natural rubber(NR)were studied.The results showed that,the dry rubber content of natural rubber latex of five rubber tree strains changed significantly with seasons,among which the average dry rubber content of GT1 latex was the largest,and the dry rubber content fluctuated the least with seasons.The storage performances of Yunyan 77-4 and Yunyan 77-2 NR were good,the t90 of GT1 NR was the shortest,the t90 of RRIM600 and Yunyan 77-4 NR was longer,and the physical properties of GT1 and PRI107 NR were better.
