增大轮胎胶料中合成橡胶用量的研究

摘要

Synthetic rubber (SR) was applied in the inner ply compound and tread compound of the light truck bias tire or OTR bias tire. The inlfuence of addition level of SR on the properties of the compounds was studied. With the increase of SR amount, the proportion of natural rubber (NR) decreased, which could change the physical properties of the compounds. However, by adjusting the NR/SR ratio and optimizing the rest of formulation, the properties of the compounds could meet requirements, while the manufacture cost was signiifcantly reduced.%针对轻型载重斜交轮胎和工程机械斜交轮胎内层帘布胶和胎冠胶，研究增大合成橡胶（SR）用量对胶料性能的影响。结果表明：降低天然橡胶（NR）用量对胶料的物理性能有不同程度的影响，但通过调整NR和SR的并用比，并对配方其余组分进行优化，胶料的性能可以满足要求，生产成本显著降低。
