耐紫外老化日间辐射降温织物的制备及性能研究
Preparation and Performance of UV-aging Resistant and Daytime Radiative Cooling Fabrics
摘要
Abstract
Outdoor textiles with radiative cooling effect can effectively protect outdoor personnel under high summer temperature.In this paper,the coated fabric with good UV-aging resistant and radiative cooling func-tions was prepared with polyester fabric as the substrate,the self-made silicone-modified acrylic epoxy emulsion and the mixed dispersion of BaSO4 particles as the finishing agents.The results showed that when the coating a-mount was 11.55 mg/cm2,the average solar reflectance of the coated radiative cooling fabric could reach 92.56%,and the average mid-infrared emissivity of the atmospheric window could reach 91.36%.Under direct sunlight,the fabric could cool down 5.2℃compared with the original polyester one.And the coated radiative cooling fabric after finishing had good wear resistance and mechanical properties.In addition,after 24 hours of UV accelerated aging,the K/S value of the coated radiative cooling fabric remained almost unchanged.The aver-age UVA transmittance of the fabric was only 1.8%,and the UPF value could reach 387.03,showing good UV-aging resistance.The coated fabric has good application prospect in the field of outdoor cooling.关键词
