| 中文摘要: |
| 采用动态硫化法制备炭黑补强高抗冲聚苯乙烯（HIPS）/苯乙烯-丁二烯-苯乙烯嵌段共聚物（SBS）/丁苯橡胶（SBR）热塑性硫化胶（TPV），考察炭黑用量对TPV物理性能的影响，通过场发射扫描电子显微镜观察动态硫化过程中橡胶相的形态演变。结果表明：在TPV的分散相中填充炭黑，可使TPV的拉伸强度和撕裂强度提高，炭黑用量（对于SBR胶料）为60份时，TPV拉伸强度和撕裂强度最大；在动态硫化过程中，橡胶相在交联的同时逐渐被撕碎为分散相，动态硫化至8 min，橡胶相呈稳定的类球状形貌，粒径为3～6?μm，表面为纳米乱片层状结构。 |

| TPV based on HIPS/SBS/SBR blending with carbon black was prepared by dynamic vulcanization．The effect of carbon black content on the physical properties of TPV was investigated，and the morphology evolution of phases tructure was observed by field emission scanning electron microscope．The results showed that the filling of carbon black in the SBR phase could improve the tensile strength and tear strength of TPV obviously；the tensile strength and tear strength of TPV were the largest when the addition level of carbon black was 60 phr（for SBR）；the rubber phase was evolved into spherical particles with the diameters of 3～6 μm at 8 min，which surface was rough and composed of large amounts of nano-layer sheet structure． |
