摘要:: 保溫隔熱材料作為建筑節能的關鍵因素，對減少建筑能耗和維持室內環境舒適至關重要。然而，傳統保溫隔熱材料在建筑領域的應用卻存在材料密度大、使用厚重、制備原料有毒等不足，且保溫阻燃性能難以滿足新一代綠色建筑的需求。作為一種新型輕質多孔材料，氣凝膠憑借其三維納米多孔結構、高比表面積和孔隙率等特性，展現出優異的隔熱性能，被視為理想的建筑保溫隔熱材料。在此基礎上，圍繞近年來建筑用氣凝膠的性能、種類及其在建筑保溫領域中的應用研究進展，探討了氣凝膠材料在建筑保溫中實際應用及節能效果，并分析了應用中面臨的潛在問題，提出了優化制備工藝、開發低成本原材料、加強資源化回收技術的研發等解決思路。以助力氣凝膠材料在技術、經濟與環境協同發展等方向上取得突破，為綠色建筑與全球節能減排目標提供高效且創新的實現方案。

Abstract:: Thermal insulation materials are crucial to building energy efficiency, playing a vital role in reducing energy consumption and maintaining indoor comfort.However, traditional insulation materials in the building industry have limitations, including high material density, heaviness, toxic raw materials and inadequate fire resistance, which fail to meet the requirements of nextgeneration green buildings. As a novel lightweight porous material, aerogel,with three-dimensional nanoporous structure, high specific surface area and porosity, exhibits outstanding thermal insulation properties, making it an ideal solution for building insulation. Based on recent advancements in the building insulation field, this paper reviews the performance, types and applications of aerogels in building insulation, discussing their practical applications and energy-saving effects in construction. It also analyzes the challenges faced in their application and proposes solutions, including optimizing preparation processes, developing low-cost raw materials and enhancing resource recycling technologies. These strategies aim to promote breakthroughs in the coordinated development of aerogels in terms of technology, economy and environment. The ultimate goal is to provide efficient and innovative approach for green buildings and contribute to global energysaving and emissionreduction targets.
