沥青路面热反射材料针对路面吸热性大，温度升高加剧“热岛效应”等问题而产生。热反射材料主要包括基料和功能性填料，现有基料存在耐污性不足及有机物挥发物（VOC）较高等问题。对此，项目首先分析路用热反射材料耐沾污机理，以构造低表面能核壳乳液及纳米微观粗糙疏水结构为设计思路，选用水为反应介质，丙烯酸和氟单体为反应单体，研究乳化剂体系、聚合工艺、共聚物结构以及交联体系对基料成膜性能的影响及作用机理，通过对其本体、表面结构表征和性能评价优化基料配方及工艺，合成低表面能耐沾污型含氟丙烯酸酯基料；选择兼具热反射和耐污特性的纳米填料，对其在含氟基料中进行超声、化学改性分散，研究单系或多系纳米粒子对热反射材料表面及本体结构、性能的影响，确定路用水基含氟丙烯酸酯热反射材料配方；将热反射材料应用于沥青混凝土中，评价其降温效果、耐磨、抗滑、耐候及耐沾污性。拟制材料预期降低沥青路面温度约10℃，可有效缓解“热岛效应”。

Heat-reflective materials used for asphalt pavement were produced under the condition that asphalt pavement exacerbated the urban heat island effect for its high heat absorbance. Heat reflecting materials consisted of base materials and functional fillers; however, existing base materials have not enough stain resistance and are with too high a volatile organic compounds (VOC) level. In order to address this problem, firstly, this project analyzed the stain resistance mechanism of heat reflecting materials that applied on pavement, then for the idea of constructing low surface energy, hydrophobic core-shell emulsion and nanometer micro rough structure, water was chose as reacting medium, acrylic acid and fluorine monomer as reaction monomer to investigate the influence of emulsion system, polymerization process, and crosslinking system on film forming property of base materials and their reaction mechanism. Through characterization of their ontology and surface structures, performance evaluation, the formula of base materials and their preparation technology were optimized, thus a low surface energy, stain resisting fluorinated acrylate heat reflecting material was synthesized. Due to its heat reflecting properties and stain resistance, nanometer fillers were selected to explore the influence of monophyly or multiphyly particles on structure and working performance of heat reflecting materials, then determine the formula of base materials. To disperse nanometer filler into base materials, ultrasonic and chemical modification were used. When heat reflecting materials were applied in asphalt mixture, their temperature reducing effect, abrasion resistance, skipping resistance and weather endurance and stain resistance were evaluated. The prepared heat reflecting materials is expected to have a about 10℃temperature reduction which will effectively relieve the urban heat island effect.
