摘　　要：本文主要研究了使用SBR152代替SBR1723应用于超高性能胎面配方中。结果表明:丁苯橡胶152等质量份数代替丁苯橡胶SBR1723应用在半钢轮胎胎面配方中,胶料的物理性能方面,定伸应力50%、100%、300%、拉伸强度、断裂伸长率、永久变型、撕裂强度等均有提升;硫化性能方面,替代后门尼黏度降低,同时焦烧时间基本无差别,这将有利于胶料的塑化,提升胎面胶料的加工性能;成品性能方面,试验轮胎的强度性能、耐久性能、高速性能均无明显差异变化;但是资金角度考虑有利于节约,企业生产经营成本呈现正向作用,企业盈利空间增大。This article focuses on the effect of replacing SBR1723 with SBR152 in the application of ultrahigh performance tread formulations.The results showed that the physical properties of rubber compound in the semi steel tire tread formula were significantly improved,including the constant tensile stress(50%,100%,300%),tensile strength,elongation at break,permanent deformation,tear strength and other indicators.In terms of vulcanization performance,the Mooney viscosity of rubber compound after replacement decreased,while the scorch time remained basically unchanged,which was conducive to improving the plasticizing effect of rubber compound,thus enhancing the processing performance of tread rubber compound.In terms of finished product performance,there were no significant changes in the strength,durability,and high-speed performance of the test tires.However,from a cost perspective,this alternative solution helps to reduce the production and operation costs of enterprises and has a positive impact on their profit margins.
