摘　　要：聚氨酯型固-固相变储能材料可以有效提高沥青的相变储能能力,从而在调节路面温度的同时,减小温度波动。基于上述背景,针对聚氨酯型固-固相变储能材料对沥青调温效果的影响展开研究。确定相变材料的分类标准,并分别研究其储能原理及具体应用情况,完成对聚氨酯型固-固相变储能材料特性的分析。在此基础上,定义周期性储热边界条件,根据沥青调温过程中内聚能密度的变化形式,推导相变储能材料的能量变化规律,从而确定聚氨酯型固-固相变储能材料对沥青调温效果的影响能力。Polyurethane type solid-solid phase change energy storage material can effectively improve the phase change energy storage capacity of asphalt,so as to reduce the temperature fluctuation while regulating the pavement temperature.Based on the above background,the influence of polyurethane-type solid-solid phase change energy storage materials on the temperature control effect of asphalt was studied.The classification standard of PCM was determined,and its energy storage principle and application were studied respectively.The characteristics of polyurethane solid-solid PCM were analyzed.On this basis,the boundary conditions of periodic heat storage were defined,and the energy variation rule of PCM was deduced according to the change form of cohesive energy density in the process of asphalt temperature regulation,so as to determine the influence of polyurethane type solid-solid PCM on the temperature regulation effect of asphalt.
