친환경 차열직물 제작 및 적용성 확대 방안 연구

초록

Outdoor public facilities that are continuously exposed to solar radiation may experience increased surface temperatures, requiring effective heat-shielding technologies. Conventional paint-coated heat-shielding fabrics have been applied to rail webs to suppress temperature rise and reduce the risk of track buckling during summer. In this study, a silicone coating was applied to extend the use of heat-shielding fabrics to public facilities, and the effect of surface color on heat-shielding performance was evaluated. The temperature reduction performance according to RGB composition was quantitatively analyzed using thermocouples and thermal imaging. The results showed that the silicone coating performance was comparable to the conventional paint coating, while the temperature reduction varied with the RGB composition. Based on these results, RGB sensitivity and a predictive relationship for heat-shielding performance were derived and applied to a standard 24-color chart to predict the relative performance of untested colors. In summary, this study provides a non-destructive evaluation and RGB-based prediction method for heat-shielding material design and color selection in public facilities.
