摘　　要：通过选取商业化的辐射制冷涂料与反射隔热涂料进行全方位的对比,探究两种材料性能差异。结果表明,在户外环境温度最高为41.6℃的测试条件下,辐射制冷涂料比反射隔热涂料温度低5.0℃,可以实现比大气环境温度低2.0℃的制冷效果,在夏日控温效果更为显著,且辐射制冷涂料的施工用量及耐人工气候老化的性能均优于反射隔热涂料,可能更有利于其大面积应用。We compare the performance of commercial radiative cooling coatings and reflective thermal insulation coatings.Our results show that under the same test condition of the maximum outdoor ambient temperature of 41.6℃,the radiative cooling coatings are 5.0℃lower than the reflective thermal insulation coatings and 2.0℃lower than the ambient temperature.It suggests that radiative cooling coatings are more efficient in building space temperature control in summer.Moreover,radiative cooling coatings require less dose and show better resistance to artificial climate aging than reflective thermal insulation coatings,indicating great potential in practical use.
