Double-component thermal insulation mortar, preparation method and thermal insulation structure thereof
The invention discloses double-component thermal insulation mortar, a preparation method and a thermal insulation structure thereof. The double-component thermal insulation mortar is composed of a component A and a component B, wherein the mass ratio of the component A to the component B is 10: (2.5-4); the component A comprises 5.0 to 20.0 percent of emulsion, 20.0 to 35.0 percent of lightweightaggregate, 0.2 to 0.5 percent of hydroxyethyl cellulose ether, 0 to 0.2 percent of wetting dispersant, 0 to 1.0 percent of coalescing agent, 0.2 to 3.0 percent of fiber, 0.05 to 0.15 percent of antiseptic bactericide and the balance of water; the component B is portland cement. According to the heat preservation structure of the double-component heat preservation mortar, a double-component heat preservation mortar layer, a flexible putty layer and a coating facing layer are sequentially arranged on the outer surface of a base layer wall body from inside to outside, and an alkali-resisting glass fiber net is embedded in the flexible putty layer. The heat conductivity coefficient of the prepared double-component thermal insulation mortar is 0.055 W/(m*K) or below, and the thermal insulationperformance is good; the drying and hardening time is short, the second time of construction can be conducted one day after the wall is mounted, and on-site worker construction operation is facilitated; the heat preservation structure is convenient to construct and good in heat preservation performance.
本发明公开了一种双组分保温砂浆、制备方法及其保温构造。这种双组分保温砂浆由甲组分和乙组分组成，质量配比为甲组分：乙组分＝10：(2.5～4)；甲组分包括：乳液5.0～20.0％、轻骨料20.0～35.0％、羟乙基纤维素醚0.2～0.5％、润湿分散剂0～0.2％、成膜助剂0～1.0％、纤维0.2～3.0％、防腐杀菌剂0.05～0.15％和余量水；乙组分为硅酸盐水泥。这种双组分保温砂浆的保温构造，基层墙体外表面由里向外依次设置有双组分保温砂浆层、柔性腻子层和涂料饰面层，柔性腻子层内嵌设有耐碱玻纤网。本发明制备的双组分保温砂浆的导热系数为0.055W/(m·K)以下，保温性能良好；干燥硬化时间短，上墙后1天即可进行第二遍施工，利于现场工人施工操作；本发明的保温构造，施工方便，保温性能好。
