一种纳米级有机化蒙脱土和SBS复合改性沥青及制备方法
摘要：
本发明涉及一种纳米级有机化蒙脱土和SBS复合改性沥青及制备方法。本发明所提供的SBS复合改性沥青包括SBS改性剂和沥青，其中还加入有有机化蒙脱土，当沥青质量为基准量1，各改性剂掺量相对沥青的质量比为：SBS：1％～6％，有机化蒙脱土：1％～10％。采用本方法制得的复合改性沥青贮存稳定性、抗老化性能提高，并在其燃烧时具有一定的“抑烟”效果，因而具有良好的综合性能，本发明工艺简单，应用方便。
摘要（英）：

The invention relates to a nanoscale organized montmorillonite and SBS composite modified asphalt and a preparation method thereof. The SBS composite modified asphalt provided by the invention comprises an SBS modifier, asphalt and organized montmorillonite which is also added; and when the mass of the asphalt is a standard mass 1, based on the mass of the asphalt, the SBS modifier accounts for 1 to 6 percent and the organized montmorillonite accounts for 1 to 10 percent. The composite modified asphalt prepared by the method has higher storage stability and ageing resistance, and has a certain smoke-resisting effect when burnt, so the composite modified asphalt has good combination property. The composite modified asphalt has the advantages of simple process and convenient application.
