Abstract:

?为了解决现有降温涂层成本高、环保性差、路面污染后降温效果显著下降等问题,制备了一种新型路用降温涂层,通过干燥时间、黏结性能、抗滑性能、耐磨耗性能试验,确定了新型路用降温涂层的最佳配比及涂抹量,系统研究了其路用性能和降温效果,揭示了路用降温涂层的微观结构与降温机理。结果表明:当基础涂层配比为3:2,涂抹量为0.8kg·m-2时,路用降温涂层干燥时间符合规范要求,并具有较好的黏结性能;掺加抗滑陶粒的路用降温涂层抗滑性能满足规范要求;路用降温涂层耐磨耗性能良好;不同类型路用降温涂层能使沥青路面温度降低5℃~9℃;降温功能性材料在路用降温涂层中具有良好的分散性,路用降温涂层呈现出新的振动峰,其内部出现了新的官能团。
