摘要
建筑保温可以有效降低建筑材料的热损失,对于保持建筑内部的舒适度起着重要的作用.提高建筑材料的保温性能至关重要,特别是通过减少加热-冷却的热量损失来实现节能.因此,研究具有优良保温性能的建筑材料已成为当前保温领域研究的重点之一.与传统的保温建筑材料相比,生物质基纤维素保温气凝胶具有低导热系数、高比表面积、可再生性、成本效益和环境友好型等优越的物理和化学特性,是未来建筑节能技术的理想新型建筑材料.本文综述了近年来生物质基纤维素保温气凝胶的制备技术、研究现状、存在的问题及在建筑材料(屋顶、内外墙和玻璃等)中的应用.最后,简要讨论了生物质基纤维素气凝胶在保温材料应用中面临的挑战,并对其未来的发展方向进行了展望.
Abstract
Thermal insulation of buildings plays an important role to reduce energy consumption for maintaining an optimal atmosphere inside the building.Hence,it is crucial to improve the thermal insulation performance of the building materials,especially to achieve energy savings through the reduction of energy losses for heating-cool-ing purposes.Therefore,the research on building materials with excellent thermal insulation properties has become one of the focuses of current thermal insulation research.Compared with traditional thermal insulation building materials,biomass-based cellulose thermal insulation aerogel has superior physical and chemical proper-ties,such as low thermal conductivity,high specific surface area,renewable,cost-effective and environment-friendly.It is an ideal new building material for future building energy saving technology.In this paper,the prepara-tion technology,research status,existing problems and application of biomass-based cellulose thermal insulation aerogel in building materials(roof,interior and exterior walls and glass,etc.)in recent years are reviewed.Finally,the challenges faced by biomass-based cellulose aerogel in the application of thermal insulation materials are briefly discussed,and its future development direction is prospected.
