Deoiled asphalt composition, 110 # road petroleum asphalt as well as preparation method and application of 110 # road petroleum asphalt
The invention relates to a deoiled asphalt composition, 110 # road petroleum asphalt as well as a preparation method and application of the deoiled asphalt composition and the 110 # road petroleum asphalt. The dispersing agent in the deoiled asphalt composition and the asphalt product can interact with asphaltene molecules, and the asphaltene particles are dispersed by reducing the size of the asphaltene particles or flocculate and weakening the coagulation behavior of the asphaltene particles or flocculate, so that the asphaltene particles or flocculate are kept in a suspended state in the blended asphalt product. The dispersing agent can form a stable complex with asphaltene molecules or aggregates, and aggregation of the asphaltene molecules is prevented or weakened by means of steric hindrance formed by non-polar groups, so that stable dispersion of all components in a blended asphalt product is guaranteed, and a good colloid structure is formed.
本发明涉及一种脱油沥青组合物、110号道路石油沥青及其制备方法和用途。本发明的脱油沥青组合物及沥青产品中的分散剂可与沥青质分子相互作用，其通过减少沥青质颗粒或絮凝物的尺寸并减弱其凝聚行为，使沥青质颗粒分散，从而在调和沥青产品中保持悬浮状态。分散剂可以通过与沥青质分子或聚集体形成稳定的配合物，借助非极性基团形成的空间位阻，阻止或减弱沥青质分子的聚集，从而保证了调和沥青产品中各组分的稳定分散，形成良好的胶体结构。
