摘　　要：随着高速公路交通流量和汽车荷重的增大以及使用年限的增加,路面病害日益显现,研发高性能化学灌浆材料已经成为当下迫切的需求。环氧树脂灌浆材料因其高强度、良好的力学性能和附着力、低收缩率和热稳定性等特点,成为一种极具发展潜力的灌浆材料。为了满足环氧灌浆材料在多方面的应用需求,已经有多种改性方法用于提高环氧灌浆材料的力学性能,如在分子链段中引入有机硅、醚基团等柔性基团,通过与聚氨酯共混形成互穿聚合物网络结构,以及添加纤维、纳米粒子等增强填料或其它方法获得高机械性能等。从结构改性、共混改性、掺杂改性以及其他方法几个方面综述了环氧灌浆材料的改性方法,并对环氧灌浆材料领域进行了展望。With the increase of highway traffic flow,vehicle load,and the service life,road surface diseases are increasingly apparent,and research and development of high-performance chemical grouting materials has become an urgent need.Epoxy resin grouting material has become a kind of grouting materials with great development potential because of its high strength,good mechanical properties,adhesion,low shrinkage and thermal stability.In order to meet the application needs of epoxy grouting materials in various aspects,there have been a variety of modification methods to improve the mechanical properties of epoxy grouting materials.For example,the flexible groups such as organosilicon and ether groups are introduced into the molecular chain segment,the interpenetrating network structure is formed by blending with polyurethane,and the reinforcement filler such as fibers and nanoparticles is added or other methods are used to obtain high mechanical properties.In this paper,the modification methods of epoxy grouting materials are reviewed from the aspects of structural modification,blending modification,doping modification and other methods,and the prospect of epoxy grouting materials field is also present.
