摘　　要：针对春风减压渣油与苯乙烯-丁二烯嵌段共聚物(SBS)相容性差、难以改性的问题,利用春风减压渣油和塔河减压渣油在组成上的互补性,采用先复配后改性的方式,改善了春风减压渣油与SBS之间的相容性,降低了春风减压渣油改性难度。从元素组成、结构参数及族组成3个方面对两种减压渣油与SBS相容性的差异进行了详细分析。最后以春风减压渣油和优选的塔河减压渣油为原料,采用均匀设计试验方法对工艺条件进行了优化,选择适宜的工艺条件,能够制备出储存稳定且性能满足“聚合物改性沥青技术要求”Ⅰ-B和Ⅰ-C指标要求的SBS改性沥青。In order to solve the problem of poor compatibility difficulty in modification of Chunfeng vacuum residue with SBS,the composition of Chunfeng vacuum residue and Tahe vacuum residue was complementary,and the method of compounding first and modifying later was adopted.The compatibility between Chunfeng vacuum residue and SBS was improved,and the modification difficulty of Chunfeng vacuum residue was reduced.The compatibility difference between the two kinds of residue was analyzed in detail from the aspects of element composition,structural parameters and group composition.Finally,using Chunfeng and preferred Tahe vacuum residue as raw materials,the process conditions were optimized by uniform design test method.SBS modified asphalt with storage stability and performance meeting the I-B and I-C specifications of“Technical Requirements of Polymer Modified Asphalt”was prepared by selecting appropriate process conditions.
