Gypsum-based sound-insulation and heat-preservation thick-layer self-leveling mortar
The invention relates to gypsum-based sound-insulation heat-preservation thick-layer self-leveling mortar which is prepared from the following components in percentage by weight: 80 to 90 percent of mixed cementing material, 8 to 10 percent of a mineral filler, 0.3 to 3.5 percent of a retarder, 0.8 to 1.3 percent of a rheology modifier, 0.0002 to 0.0005 percent of an active excitant and water. Themixed cementing material is prepared from the following components (by weight): 25 percent of ordinary Portland cement and 65 percent of alpha-hemihydrate gypsum or anhydrite. The mineral filler is vitrified microbeads. The retarder is a gypsum retarder. The rheology modifier is prepared from the following components (by weight): 0.16 to 0.2 percent of an HPMC water reducing agent, 0.1 to 0.15 percent of a defoaming agent, 0.1 to 0.15 percent of cellulose No. 400, and 0.4 to 0.8 percent of redispersible rubber powder. The active excitant is AOS powder. The gypsum-based sound-insulation heat-preservation thick-layer self-leveling mortar of the invention has the following advantages: the density is small, the weight is light, and the self-weight of a high-rise building can be reduced; noisegenerated by impact is consumed through the properties (such as damping) and the structure of the vitrified microbeads, and the sound insulation and heat preservation functions are achieved.
本发明涉及一种石膏基隔音保温厚层自流平砂浆，以重量百分比计，其成分包括：混合胶凝材料80‑90%，矿物填料8‑10%，缓凝剂0.3‑3.5%，流变改性剂0.8‑1.3%，活性激发剂0.0002‑0.0005%，水。所述的混合凝胶材料以重量百分比计，其成分包括：普通硅酸盐水泥25%，a‑半水石膏或硬石膏65%。所述的矿物填料为玻化微珠。所述的缓凝剂为石膏缓凝剂。所述的流变改性剂以重量百分比计，其成分包括：HPMC减水剂0.16‑0.2%，消泡剂0.1‑0.15%，纤维素400号0.1‑0.15%，可再分散胶粉0.4‑0.8%。所述的活性激发剂为AOS粉。本发明具有如下优点：密度小，体重轻，可以减轻高层建筑物的自重；通过玻化微珠本身的性质（如阻尼）和结构来消耗撞击产生的噪音，具有隔音，保温的功能。
