VCR412在OTR轮胎胎侧胶中的应用

试验研究高顺式聚丁二烯复合橡胶VCR412在全钢巨型工程机械子午线轮胎胎侧胶中的应用。结果表明：配方中在相同的炭黑用量情况下与镍系顺丁橡胶相比高顺式聚丁二烯复合橡胶定伸更高，且具有较好综合物理性能及较低的压缩生热；在同等300%定伸VCR412配方炭黑减量相比镍系顺丁橡胶炭黑量不变情况下，综合物理性能更好且具有优异的抗屈挠裂口增长性能及更低压缩生热。

VCR412 in OTR Tyre Sidewall Rubber

The study focus on the application of Cis-polybutadiene Rubber(PBR) VCR412 in all-steel giant OTR tyre sidewall rubber. The result shows that Cis-polybutadiene Rubber has the better tensile strength than nickel cis-polybutadiene when the compound apply same amount of carbon black, and it has better physical performance with lower stress-heating; when the compound apply same carbon black with 300% of tensile strength, the cis-polybutadiene has better physical performance, better flexibility-resistance on leakage and lower stress heating.
