Abstract: The best formulas of the radiant thermal insulation exterior coating was obtained by optimizing the radiate functional material through single-doped or multi-doped process. The test results indicated that the radiant thermal insulation exterior coating could radiate the absorption heat of the buildings. which could speed up the cooling inside. Therefore the radiant thermal insulation exterior coating was a kind of active cooling type heat insulation coating and showed good heat insulation cooling effect.

Key words: radiant, functional material, doped dosage;absolute temperature rise, exterior thermal insulation coatin

摘要： 采用单掺、复掺试验方法，优化辐射型功能填料的掺量，获得辐射型外墙隔热涂料的最佳配方。绝对温升、半球发射率等性能测试表明，辐射型外墙隔热涂料对建筑物吸收的热量具有一定的发射功能，可加快室内降温速率，从而达到良好的隔热降温效果，是一种主动降温型隔热涂料。
