Gypsum mortar containing vitrified micro bubbles
The invention provides gypsum mortar containing vitrified micro bubbles. The gypsum mortar comprises gypsum powder, sand, the vitrified micro bubbles, cement, silicon dioxide, a water repellent, rubber powder, cellulose, a retarder and a water retaining agent, and is prepared from the following raw materials in parts by weight: 60-70 parts of gypsum powder, 50-60 parts of sand, 20-30 parts of vitrified micro bubbles, 7-9 parts of cement, 3-5 parts of silicon dioxide, 1-2 parts of the water repellent, 1-2 parts of rubber powder, 0.2-0.6 part of cellulose, 2-4 parts of the retarder, 2-5 parts ofthe water retaining agent and 0.7-2 part of a water reducing agent. The vitrified micro bubbles are added, so that the heat preservation and insulation performance of the gypsum mortar is improved, the noise transmission is reduced, the sound insulation effect is improved, the slurry setting time is proper, the fluidity is high, and the water retention rate is high; through chemical reaction andphysical action of silicon dioxide and the water repellent, the strength and the water resistance of the gypsum mortar are improved.
本发明提供了一种含有玻化微珠的石膏砂浆，包括：石膏粉、砂、玻化微珠、水泥、二氧化硅、憎水剂、胶粉、纤维素、缓凝剂和保水剂；具体配方由以下重量份的原料制成：石膏粉60‑70份、砂50‑60份、玻化微珠20‑30份、水泥7‑9份、二氧化硅3‑5份、憎水剂1‑2份、胶粉1‑2份、纤维素0.2‑0.6份、缓凝剂2‑4份和保水剂2‑5份和减水剂0.7‑2份。本发明添加玻化微珠，提高石膏砂浆的保温隔热性能，降低噪音传递，增加隔音效果，浆体凝结时间适宜，流动度大，保水率好；通过二氧化硅和憎水剂的化学反应和物理作用后，提高了石膏砂浆的强度和耐水性。
