中文摘要: |
主要介绍稀土顺丁橡胶(BR)、稀土异戊橡胶(IR)和稀土丁异戊橡胶(BIR)的生产和研究状况。钕系BR(Nd-BR)是BR中顺式含量最高(顺式-1,4-结构物质的量分数可达0.98以上)、综合性能最好的胶种,将替代其他BR成为高性能子午线轮胎的主要原料。稀土IR合成技术为我国首创,钕系IR(Nd-IR)主要应用于医用器械领域,钛系IR(Ti-IR)和Nd-IR主要应用于轮胎中。而钕系BIR(Nd-BIR)脆性温度低于-80 ℃,Nd-BIR在低温材料和轮胎中具有广阔应用前景。 |
英文摘要: |
In this paper,the production and research status of rare earth butadiene rubber(BR),rare earth isoprene rubber(IR) and rare earth butadiene isoprene rubber(BIR) are introduced. Nd-BR has the highest content of cis-structure in all types of BR materials with the cis-1,4-structure content of 0. 98 or more, it possesses the best comprehensive performance and will replace the other BR as the main raw material for high-performance radial tire. The synthesis technology of rare earth IR was firstly developed in China. Nd-IR is mainly used in the field of medical equipments,and Ti-IR and Nd-IR are mainly used in tires. The brittle temperature of Nd-BIR is lower than -80 ℃,and so Nd-BIR is showing broad application prospects in low temperature materials and tires. |
