Long-acting composite microcapsule asphalt pavement self-repairing agent and application thereof
The invention relates to a long-acting composite microcapsule bituminous pavement self-repairing agent and application thereof.The self-repairing agent comprises an external large microcapsule and an internal small microcapsule, the external large microcapsule is composed of a large microcapsule wall material, a large microcapsule core material wrapped in the large microcapsule wall material and a nanometer reinforcing agent dispersed in the large microcapsule core material, and the internal small microcapsule is composed of an internal small microcapsule and an external small microcapsule. The internal small microcapsules are dispersed in the large microcapsule core material, and each internal small microcapsule is composed of a small microcapsule wall material and a small microcapsule core material wrapped in the small microcapsule wall material. The composite microcapsule can realize asphalt pavement crack self-repairing, the nanometer reinforcing agent dispersed in the core material enhances the repairing effect, the mechanical property and the anti-fatigue property of asphalt concrete are improved, the service life of the asphalt concrete is prolonged, the internal small microcapsule prolongs the timeliness of asphalt pavement self-repairing, and the self-repairing effect of the asphalt pavement is improved. Therefore, the service quality and the service life of the asphalt pavement are greatly improved and prolonged.
本发明涉及一种长效复合型微胶囊沥青路面自修复剂及其应用，该自修复剂包括外部大微胶囊与内部小微胶囊，所述外部大微胶囊由大微胶囊壁材、包裹于大微胶囊壁材内的大微胶囊芯材、以及分散于大微胶囊芯材中的纳米增强剂组成，所述的内部小微胶囊分散于所述大微胶囊芯材中，所述内部小微胶囊由小微胶囊壁材与包裹于小微胶囊壁材内的小微胶囊芯材组成。本发明的复合型微胶囊可实现沥青路面裂缝自修复，分散于芯材中的纳米增强剂增强了修复效果，并提高沥青混凝土力学性能、抗疲劳性能及使用寿命，内部小微胶囊延长沥青路面自修复的时效性，从而使沥青路面的服役质量和使用寿命得到大幅度提升。
