Double-layer self-healing microcapsule, self-healing asphalt mixture and preparation method thereof
The invention provides a double-layer self-healing microcapsule, a self-healing asphalt mixture and a preparation method of the double-layer self-healing microcapsule and the self-healing asphalt mixture, and aims to solve the technical problem that an asphalt pavement is easy to damage and difficult to repair fundamentally. The double-layer self-healing microcapsule shell is broken under the change of stress or temperature, and a healing agent is automatically released to a damaged part, so that a quick and accurate self-repairing function is realized; the self-healing asphalt mixture disclosed by the invention is excellent in pavement performance, simple in preparation process and non-toxic and harmless in raw materials, can enhance the high-temperature stability, low-temperature crack resistance, water stability, maximum load ratio and crack healing rate of an asphalt pavement, and has great significance in prolonging the service life of the asphalt pavement.
本申请提供一种双层自愈微胶囊、自愈合型沥青混合料及其制备方法，旨在解决难以从根本上解决沥青路面易损、不易修复的技术问题。本申请双层自愈微胶囊壳体在应力或温度变化下破裂，自动释放愈合剂至损伤部位，实现快速且精准的自我修复功能；本申请自愈合型沥青混合料路用性能优良，制备工艺简单、原料无毒无害，可以增强沥青路面高温稳定性、低温抗裂性、水稳定性、最大荷载比值和裂纹愈合率，对延长沥青路面使用寿命具有重大意义。
