| 摘要: | 本計畫擬開發一種高效率隔熱應用材料，其具有低熱傳導係數，高強度與良好耐候性等特性，可廣泛應用於建築物外殼，達到節能減碳，降低能源消耗之功效。計畫中將以二氧化矽氣凝膠為主體之建築用隔熱保溫之塗料，建立氣凝膠增強產品材料多項性質(比如機械性質分析、親疏水性分析、微結構分析、比表面積分析、孔隙度分析、漿料分散及聚集分析、黏著力分析、材料表面化學微組成分析以及熱傳導性質分析)檢測平台，以其了解結構－材料性質之關係，另外利用化學微組成分析技術，可進一步了解材料表面官能基與黏著力之關係。最後所完成二氧化矽氣凝膠增強塗料性質，如依SGS ASTM C518-15熱傳導率K值可達或是小於0.12 W/mK，黏著力百格測試儀可達5B，機械性質可達20 MPa，並符合政府防火耐燃法規之要求。 ;This project intends to develop high-efficiency thermal insulation materials, which have the characteristics of low thermal conductivity, high strength and good weather resistance. It can be widely used in buildings to achieve energy saving, carbon reduction, and energy consumption. In the project, silica aerogel will be used as the main building insulation coating to establish aerogel-enhanced product materials. Also, multiple properties (such as mechanical property analysis, hydrophilic and hydrophobic analysis, microstructure analysis, specific surface area analysis, porosity analysis, slurry dispersion and aggregation analysis, adhesive force analysis, material surface chemical micro-composition analysis, and thermal conductivity analysis) detection platform will be established to understand the relationship between structure and material properties. For example, chemical micro-composition analysis technology will be used to further understand the relationship between surface functional groups and adhesion. Finally, for the silica aerogel-enhanced insulation materials, several properties will be achieved. For example, according to SGS ASTM C518-15, the thermal conductivity K value can reach or be less than 0.12 W/mK, adhesion can reach the degree of 5B under adhesion cross-cut testers. In addition, the mechanical properties can reach 20 MPa, and the aerogel-based insulation materials can meet the requirements of government fire and flame resistance regulations. |
