沥青路面水性聚氨酯丙烯酸热反射涂料制备OA北大核心CSTPCD
Preparation of waterborne poly(urethane acrylic)heat-reflective coatings for asphalt pavement
以异佛尔酮二异氰酸酯(IPDI)、聚丙二醇(PPG)等原料制备水性聚氨酯(WPU),通过丙烯酸单体和交联剂改性WPU制得水性聚氨酯丙烯酸(WPUA)乳液.利用傅里叶变换红外光谱(FTIR)分析WPUA的官能团,利用铅笔硬度和百格划线法对WPUA膜的硬度、附着力进行测定,利用水接触角试验对WPUA膜的疏水性能进行测试;以降温值、黏度值、光泽度作为评价指标,借助正交试验设计确定WPUA热反射涂料的最佳配方;通过室内太阳辐射模拟装置以及室外太阳照射试验…查看全部>>
Waterborne polyurethane(WPU)was prepared by using isophorone diisocyanate(IPDI),polypropylene gly-col(PPG)as raw materials,and it was further modified by using an acrylic monomer and a crosslinking agent to prepare the waterborne poly(urethane acrylic acid)(WPUA)lotion.The functional groups of the as-prepared WPUA were ana-lyzed by Fourier-transform infrared spectroscopy.The hardness and adhesion of the WPUA film was measured by using pencil hardness and hun…查看全部>>
