摘　　要：为了研究不同的萃取液对于弹性体改性沥青防水卷材可溶物含量的影响,利用索氏提取器对弹性体改性沥青防水卷材试件进行了反复试验,考察了萃取液对可溶物含量的影响。结果表明,环己烷、四氯化碳、二硫化碳、乙腈、苯可作为可溶物含量的萃取液,而脂肪烃类、醇类、醚类、酯类、酮类均不能作为可溶物含量的萃取液。试验为进一步修订GB/T 328.26—2007标准和改进试验方法提供了有力的参考。In order to research the effect on soluble contents of the styrene butadiene styrene（SBS） modified bituminous waterproof sheet by the different extraction solvent, the experiments were carried out by Soxhlct extractor. The influence of the different extraction solvent on soluble contents of the SBS modified bituminous waterproof sheet was mainly studied. Results show that, cyclohexane, carbon tetrachloride, carbon disulfide, benzene and acetonitrile can be used as the extract of the soluble content, but aliphatic hydrocarbon, alcohols, ethers, esters and ketones were not. This test provides a strong frame of reference for revising and improving test method of GB / T 328.26-2007.
