乳化沥青施工简便,不污染环境,在道路工程等领域有非常广泛的应用。以SBS为改性剂,采用边改性边乳化的方法制备了一种阳离子改性乳化沥青,并对影响改性乳化沥青制备的主要因素如表面活性剂掺量、SBS改性剂掺量、pH值等进行了试验,确定了比较适宜的反应条件。 Emulsified asphalt construction is simple, does not pollute the environment, has a very wide range of applications in areas such as road engineering. Using SBS as modifier, a cationic modified emulsified asphalt was prepared by side modification and emulsification. The main factors influencing the preparation of modified emulsified asphalt were the content of surfactant, the content of SBS modifier, pH value were tested to determine the more appropriate reaction conditions.
