【摘要】 研究了中试产品溶液共沉型中乙烯基聚丁二烯橡胶（ＭＶＢＲ）物理力学性能，表明ＭＶＢＲ硫化胶具有优异的低生热性、耐磨性和耐热老化性；借助ＭＡＫ－０４型动态粘弹谱仪研究了ＭＶＢＲ的动态力学性能．表明ＭＶＢＲ生胶具有双峰的宽ｔｇδ，玻璃化转变温度为－９９℃和－１５℃，与ＢＲ９０００和ＳＢＲ１５０２相比，在温度为０℃ＭＶＢＲ的ｔｇδ高于ＢＲ９０００和ＳＢＲ１５０２，而在温度为５０℃时，ＭＶＢＲ的ｔｇδ低于ＳＢＲ１５０２，而且稍低于ＢＲ９０００，说明ＭＶＢＲ的抗湿滑性能优于ＢＲ９０００和ＳＢＲ１５０２，而滚动阻力却最小，即ＭＶＢＲ可实现高抗湿滑性和低滚动阻力的综合平衡。更多还原

【Abstract】 The physical & mychanical properties of coagulated polybutadiene rubber with medium vinylcontent(MVBR)in 50L caldron were studied which showed that MVBR vulcanizates had the excellent low heat - built up,the good wear resistance and heat - aging resistance.The dynamicproperty of MVBR was also investigated by MAK - 04 type dynamic viscoelatometer.The resultindicated that the raw MVBR had wider tga values with double peeks and that the Tgs were 99t and - 15℃,respectively.The tgo value of MVBR at of of the temperature was higherthan those of BR9000 and SBR1502,rbuubers while the tga value of MVBR at 50t of the temperature was lower than those of SBR1502 and BR9000, which showed that the wet -- skid resistance of MVBR was better than those of BR9000 and SBR1502, while the roll loss of MVBR wasthe least among the three kinds of rubbers.更多还原
