一、引言 外墙体的外保温节能技术(以下简称外保温技术),因其节能效果显著(减少热桥,提高外墙内表面温度,从而增加舒适程度),且便于旧建筑的节能改造,已成为当今的发展方向。 但外保温技术,无论在实现外保温层与墙体的可靠联接方面,还是在其外护围层抗恶劣环境(风吹雨淋,寒暑冻融,日光曝晒)方面,都存在着许多难点。另外,降低造价以适合国情,也是发展外保

I. INTRODUCTION External wall thermal insulation and energy saving technology (hereinafter referred to as external thermal insulation technology) is significant because of its energy-saving effect (reducing the thermal bridge, increasing the internal surface temperature of the external wall, thereby increasing the degree of comfort), and facilitating the energy-saving renovation of old buildings. Has become the direction of development today. However, the external thermal insulation technology has many difficulties in achieving reliable connection between the external thermal insulation layer and the wall, and in the external environment of the external protection surrounding the harsh environment (wind and rain, cold and thaw, and sunlight exposure). In addition, reducing the cost to suit the national conditions is also the development of foreign insurance.
