• 一种温拌用橡塑合金及其制备方法与应用,
    本发明涉及公路沥青技术领域,具体涉及一种温拌用橡塑合金及其制备方法与应用。本发明中温拌用橡塑合金使沥青在拌合过程中更好地在集料上铺展开来,降低了沥青与集料界面的接触角;嵌段高分子聚合物的亲油基链段与橡塑合金或沥青结合,结晶水挥发,形成润滑膜,亲水基吸附在集料表面,润滑膜在温度下降时能够抵消沥青黏度增大的影响,提高沥青混合料低温施工和易性,达到温拌效果。本发明提供的温拌橡塑合金制备方法新颖,设计巧妙。温拌沥青在工艺生产中间环节少,用料透明可监控,工艺简单易操控。......

  • 基于熔融接枝烷基链提升聚丁烯发泡行为研究,韩冲 孙并臻 宫瑞英 李朝旭,高分子学报,2020
    聚烯烃材料引入长支化结构,能够提升材料熔体强度和异相成核作用,使聚合物具备更加优异的发泡性能,从而扩宽材料的应用领域. 本文利用甲基丙烯酸十八烷基酯(SMA)熔融改性聚丁烯(PB),发现其链段缠结程度提升,发泡行为改善. 通过红外谱图的化学结构分析以及材料的力学性能分析,发现随着SMA添加量的增加,材料拉伸强度降低,冲击强度呈现先升高后降低的趋势. 差示扫描量热(DSC)的分析结果表明改性PB的结晶度下降. 采用间歇釜式法制备PB发泡珠粒,利用扫描电子显微镜(SEM)研究发泡珠粒泡孔结构,......
