摘要
利用吡啶改性丁苯橡胶 ( PSBR)乳液与正溴丙烷反应后生成 PSBR季铵盐 ,再与铝酸酯、钛酸酯以及活性硅烷醇反应 ,制得有机 -无机杂化弹性体 PSBR胶片 ( PSBR-Mn Om) .经与天然橡胶并用 ,制成复合硫化胶 .复合硫化胶的力学性能较好 ,并具有较高的滞后损耗 .其压缩永久变形率与天然橡胶相似 .用 FTIR、高分辨 NMR、DSC和 TG等手段对其结构进行了分析 ,并认为在含有金属的复合硫化胶中可能存在“介稳巨大配合物”。
Pyridinium salt was produced by using reaction of vinylpyridine SBR(PSBR) latex with propyl bromide, and then it reacted with aluminum alkoxide, alkyl titanate and active silanol to prepare a organic/inorganic hybrid elastomer latex(PSBR M n O m ). A kind of composite vulcanizate was obtained after the hybrid elastomer was compounded with natural rubber. Its mechanical performance is rather good and its hysteresis loss is quite high. In addition, it is similar in compression set to NR. Its structure was analyzed by FTIR, high resolution NMR, DSC and TG etc .. It is believed that the existence of 'huge metastable complexes' in the metal containing composite vulcanizate may improve its mechanical properties.
