EPS薄抹灰外墙外保温系统不是孤立的体系,从构造上,它大体上是由主体结构墙体、界面层(粘结砂浆)、保温层(EPS板)、保护层(抗裂砂浆和耐碱玻纤网格布)以及外装饰防水层(弹性腻子、外墙涂料)等组成,形成一个多功能的复合墙体;其体系长期暴露于大气环境中,对耐久性有更高的要求。在聚合物砂浆抹面的实际施工中,经常使用普通腻子找平,而该类腻子极易开裂,会影响保温层及外事面的装饰效果。应先用耐水的弹性腻子找平,再用弹性涂料涂刷,使EPS板的外层形成具有弹性的保护体。
The EPS plastering exterior wall insulation system is not an isolated system. In terms of its structure, it is mainly composed of a main structure wall, an interface layer (adhesive mortar), an insulation layer (EPS board), a protective layer (cracking mortar and Alkali-resistant glass fiber mesh cloth) and exterior decorative waterproof layer (elastic putty, exterior wall paint), etc., to form a multi-functional composite wall; its system is exposed to atmospheric environment for a long time, and has higher requirements for durability. . In the actual construction of polymer mortar plastering, ordinary putty leveling is often used, and the putty is easy to crack, which will affect the decorative effect of the insulation layer and the external surface. Should be leveled with water-resistant elastic putty, and then brushed with elastic paint, so that the outer layer of the EPS board has a flexible protection body.
