【摘要】 在沥青中添加纳米材料是沥青改性的方法之一。纳米材料本身的结构与性能及其在沥青中的分散稳定性,是纳米改性沥青优异性能得以发挥和体现的关键因素。纳米氧化锌具有大比表面积和高表面活性,其对石油沥青路用性能的改善作用已得到证实。本文着重于研究纳米氧化锌的表面改性及其对煤沥青路用性能的改善作用。实验中,我们通过变换改性剂和改性方法,提高了纳米氧化锌的疏水性和分散稳定性,这将有利于其在煤沥青中的使用。更多还原

【Abstract】 Adding the nano-materials into asphalt is one of the methods for modifying asphalt.There are two factors deciding the performance of modified asphalt.One is the nano-materials’ characteristics.The other one is the dispersity between the nano-materials and asphalt.The nano-ZnO is provided with big specific surface area and surface energy.Its melioration effect on asphalt has been confirmed.My paper primarily research modifying the nano-ZnO and its melioration effect on coal bitumen.In the study,we change the modifier and the methods,so nano-ZnO’s hydrophobicity and dispersity are enhanced.It is propitious to be used into coal bitumen.更多还原
