加强建筑节能是推进绿色建筑的一项重要工作,也是绿色建材未来发展的主攻方向之一。而保温隔热材料由于具有独特的性能和用途,国内外诸多学者对其进行了深入的研究。对于建筑屋面保温节能,关注点主要集中于影响材料导热系数的主要因素如表观密度、孔隙结构、湿度变化以及温度变化。依据主要因素概述了聚氨酯、泡沫混凝土、真空板的研究现状及应用。结合常用的3种保温材料,提出利用不同的保温材料进行复合组装,进而达到各方面性能的提升。
Strengthening building energy conservation is an important task in promoting green building and is also one of the main directions for the future development of green building materials. The insulation material due to its unique properties and uses, many scholars at home and abroad carried out in-depth research. For building roof insulation and energy conservation, the focus is mainly on the thermal conductivity of materials that affect the main factors such as apparent density, pore structure, humidity and temperature changes. The research status and application of polyurethane, foam concrete and vacuum plate are summarized based on the main factors. Combined with the commonly used three kinds of insulation materials, the proposed use of different insulation materials for composite assembly, and thus achieve all aspects of performance improvement.
