摘要
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。
Building energy conservation is an important work to promote green building,but also is one of the main direction of future development of green building materials.Because of its unique properties and applications,many scholars at home and abroad have studied it deeply.For the thermal insulation and energy saving of building roof,the focus is mainly on the main factors that affect the thermal conductivity of materials,such as apparent density,pore structure,humidity and temperature.Based on the main factors,the present situation and application of polyurethane,foam concrete and vacuum plate were summarized.Combined with the three kinds of commonly used thermal insulation materials,the use of different thermal insulation materials to carry out composite assembly was put forward,to achieve the improvement of all aspects of performance.
