研究环保油对丁苯橡胶(SBR1500和SBR1500/SBR1516并用胶)性能的影响。结果表明,环保油代替芳烃油后,SBR1500的定伸应力、拉伸强度相近,硬度、拉断伸长率、撕裂强度稍低,回弹性略有提高,压缩疲劳试验的温升下降、永久变形变小;硫化胶的硬度、拉伸强度、定伸应力提高,拉断伸长率、撕裂强度降低,回弹性降低、压缩疲劳试验的温升下降、永久变形减小,耐热老化性能相近,抗湿滑性能改善,滚动阻力增大,耐磨性能略差。
The effect of environment friendly oil on the performance of SBR1500 and SBR1500 / SBR1516 was studied. The results show that, after the replacement of aromatic oil with environmentally friendly oil, SBR1500 has similar ultimate tensile strength and tensile strength, slightly lower hardness, tensile elongation and tear strength, slightly higher resilience, lower temperature rise of compression fatigue test, permanent The deformation becomes smaller; vulcanized rubber hardness, tensile strength, tensile stress increases, elongation at break, tear strength decreases, the resilience decreases, compression fatigue test temperature drop, permanent deformation decreases, heat aging resistance Similar, improved wet skid resistance, rolling resistance increases, slightly worse wear resistance.
