摘要:
通过在硫磺中添加H2S抑制剂来制备改性硫磺颗粒(MSP),采用亚甲基蓝分光光度法测定改性硫磺颗粒与沥青混合加热过程中H2S释放量,并讨论H2S主抑制剂、辅助抑制剂的种类和用量对H2S释放量的影响,优化改性硫磺颗粒配方.结果表明:二硫化物抑制剂是最佳的主抑制剂,且随主抑制剂用量的增加,H2S抑制效果增强; 少量的协同抑制剂极大地提高了改性硫磺颗粒对H2S的抑制能力.在最佳配方下,160 ℃时改性硫磺颗粒与沥青共混时H2S释放量为0.032 μg/g,与纯硫磺相比H2S释放量降至0.68%; 150 ℃时不同配方改性硫磺颗粒与沥青共混时H2S释放量为0.012~0.156 μg/g,而纯硫磺与沥青共混时H2S释放量为0.956 μg/g.添加适量改性硫磺颗粒,沥青混合料的动稳定度由1 073次/mm提高至2 410次/mm,冻融劈裂强度比由75.3%提高至 84.4%.改性硫磺颗粒具有显著降低H2S释放量、增强路面强度、改善抗水损害能力等优点.
Abstract:
MSP(modified sulphur pellets)were prepared by adding H2S-inhibitors in an amount sufficient to reduce or inhibit the H2S evolution which was determined by methylene blue spectrophotometry. The effects of different kinds and amounts of H2S-inhibitors on the H2S evolution were also discussed in detail to optimize the compositions of MSP. The results indicate that disulphide can serve as the best major inhibitor, and the suppressive effect increases with the increase in the amount of disulphide. The H2S evolution is significantly reduced by adding a small quantity of coordinate reducing additives. The H2S evolution quantity for MSP is 0.032 μg/g during the reaction of sulphur with asphalt for 1h at 160 ℃, which decreases to 0.68% compared with pure sulphur. The H2S evolution quantity for MSP with different compositions ranges from 0.012 to 0.156 μg/g, while that for pure sulphur is 0.956 μg/g at 150 ℃. The addition of MSP in asphalt results in sharp increase in the dynamic stability(from 1 073 times/mm to 2 410 times/mm)and also a moderate increase in the freeze-thaw cleavage strength(from 75.3%to 84.4%). The results of the study suggest that MSP can significantly reduce the H2S evolution, strengthen the intensity of asphalt pavements and improve the water damage resistance of asphalt pavements.
