摘要
有机膨润土在沥青中形成剥离型结构,因此能够有效提高沥青的高低温性能、抗老化能力。针对膨润土的结构与特性进行了介绍,综述了有机膨润土的制备方法与有机膨润土的改性机理,阐述了有机膨润土单一改性与复配改性沥青的作用与机理,并对有机膨润土改性沥青的发展与研究方向进行了展望。
Organic bentonite modified asphalt has exfoliated structure type,so it can effectively improve the high and low temperature properties and anti-aging ability of asphalt. The structure and properties of bentonite is introduced. The production methods of organic modification and the modification mechanisms of bentonite are also reviewed. The effects and mechanisms of single component and complex modified asphalt are summarized. The prospects and development trend of the organic bentonite modified asphalt are discussed.
