摘要:

保溫隔熱材料作為建筑節(jié)能的關(guān)鍵因素，對減少建筑能耗和維持室內(nèi)環(huán)境舒適至關(guān)重要。然而，傳統(tǒng)保溫隔熱材料在建筑領(lǐng)域的應(yīng)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(zhì)多孔材料，氣凝膠憑借其三維納米多孔結(jié)構(gòu)、高比表面積和孔隙率等特性，展現(xiàn)出優(yōu)異的隔熱性能，被視為理想的建筑保溫隔熱材料。在此基礎(chǔ)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(lǐng)域中的應(yīng)用研究進(jìn)展，探討了氣凝膠材料在建筑保溫中實際應(yīng)用及節(jié)能效果，并分析了應(yīng)用中面臨的潛在問題，提出了優(yōu)化制備工藝、開發(fā)低成本原材料、加強(qiáng)資源化回收技術(shù)的研發(fā)等解決思路。以助力氣凝膠材料在技術(shù)、經(jīng)濟(jì)與環(huán)境協(xié)同發(fā)展等方向上取得突破，為綠色建筑與全球節(jié)能減排目標(biāo)提供高效且創(chuàng)新的實現(xiàn)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�瞘eneration 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�瞫aving and emission�瞨eduction targets.
