摘要
对钕系顺丁橡胶（ＮｄＢＲ）进行生胶和胶料性能试验，并与常规使用的镍系顺丁橡胶（ＮｉＢＲ）进行对比。结果表明，ＮｄＢＲ相对分子质量明显高于ＮｉＢＲ，且胶料耐热氧老化性优于ＮｉＢＲ。针对轮胎胎面胶配方中掺用５０份ＮｄＢＲ３后其胶料加工性能不如ＮｉＢＲ的问题，改变加工条件，使其加工性能达到或超过ＮｉＢＲ，硫化胶耐磨性、耐疲劳性能和耐屈挠龟裂性能以及耐热空气老化性能优于ＮｉＢＲ，用其制做９００－２０里程试验轮胎，其耐磨性比ＮｉＢＲ对比轮胎提高１６９％。
An experimental study was made on the properties of raw NdBR and its compound by using conventional NiBR as control.The results showed that the molecular weight of NdBR was significantly higher than that of NiBR and the thermal oxidative ageing property of NdBR compound was better than that of NiBR compound;the processibility of the tread compound with 50 parts of NdBR 3 was poorer than that of equivalent NiBR tread compound,but it could reach or exceed that of the latter by adjusting the processing conditions;the wear resistance,fatigue property ,flexing crack resistance and hot air ageing property of NdBR vulcanizate were better than those of NiBR vulcanizate;the wear resistance of 9 00-20 test tire made with NdBR was 16 9% higher than that of NiBR control tire.
