Road composite phase change material for asphalt pavement and preparation method of road composite phase change material
The invention relates to a road composite phase change material for an asphalt pavement. The road composite phase change material comprises a granular phase change material, a polyurethane polymer and graphite, wherein the polyurethane polymer uniformly covers the surface of the granular phase change material, and the graphite is dispersed in the polymer. According to the composite phase-change material for the road, the phase-change material particles are packaged, and the compact and continuous wrapping effect is achieved. And the wrapping coating coated on the surfaces of the particles has hardness and elasticity consistent with those of an asphalt material, so that the rut pressure resistance of the whole road material can be improved, and the coating is prevented from cracking. And the graphite material is doped, so that the heat conduction efficiency is improved, and the temperature regulation performance is not reduced.
本发明涉及一种沥青路面使用的路用复合相变材料，路用复合相变材料包括颗粒状相变材料以及均匀覆盖上述颗粒状相变材料表面的聚氨酯类聚合物以及分散在聚合物中的石墨。本发明的路用复合相变材料，对相变材料颗粒进行封装，达到包裹密实、连续的效果。在颗粒表面涂上的包裹涂层具有与沥青材料相一致的硬度和弹性，能够提高整体路用材料的抗车辙压力，并保持涂层不开裂。掺入石墨材料，同时提高热量传导效率，保证调温性能不下降。
