1、武汉理工大学研究生课程论文建筑外墙保温技术及XPS节能材料(武汉理工大学材料学院)摘要:随着能源短缺的日益严重,如何节能降耗成为整个社会共同关注的话题。在建筑领域,国家强制性要求建筑物要达到一定的节能标准,这就对建筑材料提出了更高的要求。近年来我国保温技术水平已有很大提高,保温材料的品种及生产能力不断扩大,但整体保温节能效益较发达国家还有相当大的差距。针对目前外墙内保温的缺点,介绍了外墙外保温的发展和特点,归纳了外墙外保温技术的优势,并展望了建筑外墙外保温技术的发展前景,对建筑外墙外保温节能技术
2、的推广具有一定的指导意义,并介绍了建筑外墙外保温节能材料的类型和特性。XPS板外墙外保温系统的组成材料有)XPS板、界面处理剂、专用粘结剂或聚合物胶泥、耐碱玻纤网格布、机械锚固件和饰面材料等。工程中采用XPS外墙外保温技术,可提高建筑物的节能和保温效果,并具有防水效果佳、缩短工期、施工便捷等优点。关键词:绝热保温材料;外墙内保温;外墙外保温;挤塑聚苯乙烯泡沫板【中图分类号】TU551.3文献标识码:BEnergy-savingTechniqueandMaterialofExternalWalli
