Phase change heat storage-reflective heat insulation composite functional cooling pavement material, preparation method and application thereof
The invention relates to the technical field of pavement materials, and particularly discloses a phase change heat storage-reflective heat insulation composite functional cooling pavement material and a preparation method and application thereof. The phase change heat storage-reflective heat insulation composite functional cooling pavement material comprises an asphalt mixture and a reflective heat insulation coating, and the reflective heat insulation coating is coated on the surface of the asphalt mixture; the asphalt mixture is prepared from the following raw materials in percentage by weight: 50 to 80 percent of coarse aggregate, 10 to 20 percent of fine aggregate, 0.1 to 15 percent of filler, 4 to 7 percent of asphalt, 0.05 to 0.5 percent of fiber and 0.01 to 0.1 percent of phase change material, wherein the phase change temperature of the phase change material is from 30 to 60 DEG C. The phase change material and the reflective heat insulation coating are combined for use so that the cooling effect of the asphalt pavement is more remarkable, and the combined action of melting and heat absorption of the phase-change material and the reflective heat-insulation coating is achieved.
本申请涉及路面材料的技术领域，具体公开了一种相变储热‑反射隔热复合功能型降温路面材料、制备方法及其应用。该相变储热‑反射隔热复合功能型降温路面材料，包括：沥青混合料和反射隔热涂料，所述反射隔热涂料涂覆在所述沥青混合料表面；所述沥青混合料由包含以下重量百分比的原料制成：粗集料50‑80％，细集料10‑20％，填料0.1‑15％，沥青4‑7％、纤维0.05‑0.5％以及相变材料0.01‑0.1％，所述相变材料的相变温度为30℃‑60℃。本发明通过将相变材料和反射隔热涂料的结合使用，使得沥青路面降温效果更佳显著，是相变材料和反射隔热涂料熔化吸热的共同作用。
