摘　　要：通过向建筑沥青中加入SEBS磺化得到改性磺化沥青,研究了磺化剂用量对磺化沥青降滤失性能的影响。并对磺化沥青进行了扫描电镜、Zeta电位、降滤失性能及配伍性研究。结果表明,当SEBS加量为5%,磺化比为1∶0.7时,高温高压滤失量达到24 m L,高温高压滤失量降低率达到55.56%,具有良好的降滤失性能;改性后的磺化沥青具有较好的配伍性,当样品加量达到2%,高温高压滤失量降低率达到了45.45%,说明改性磺化沥青具有良好的封堵性能。The construction asphalt modified with SEBS was sulfonated,and the effect of the amount of sulfonation agent on the loss-reduction performance of sulfonated asphalt was studied.The sulfonated asphalt was studied by scanning electron microscopy,Zeta potential,filtration loss performance and compatibility.The results show that when the amount of SEBS is 5%and the sulfonation ratio is 1∶0.7,the filtration loss of high temperature and high pressure reaches 24 mL,and the reduction rate of high temperature and high pressure filtration loss reaches 55.56%,the modified sulfonated asphalt has good compatibility.When the sample amount reached 2%,the high temperature and high pressure filtration loss reduction rate reaches 45.45%,indicating that the modified sulfonated asphalt has good sealing performance.
