Sound insulation mortar for floor and preparation method of sound insulation mortar
The invention relates to sound insulation mortar for a floor and a preparation method of the sound insulation mortar. The sound insulation mortar comprises the following raw material components: 38-42parts of cement, 40-44 parts of stone powder, 20-22 parts of aggregate A, 8-10 parts of aggregate B, 10-15 parts of aggregate C, 1-3 parts of rubber powder, 0.1-0.2 part of cellulose ether, 0.05-0.15part of fibers, 0.4-1 part of silicon dioxide aerogel, 0.8-0.15 part of guar gum and water, wherein the water accounts for 46.5-46.8% of the total amount of the dry powder. The preparation method comprises the following steps: sequentially placing the rubber powder, the cellulose ether, the fibers, the silicon dioxide aerogel and the guar gum into a small stirrer for independently stirring, and after the materials are uniformly stirred, placing the materials into a bag, wherein the materials are called as premixed small materials; and conveying the cement, the stone powder, the aggregate A, the aggregate B and the aggregate C to a drum-type stirrer, and conveying the premixed small materials to the drum-type stirrer for mixing and stirring. The mortar has elasticity and a nano porous network structure after being condensed, so that solid heat conduction of a floor slab is effectively inhibited; and network pores are filled with gaseous dispersion media, vibration generated by impact can cause vibration friction of the media in the floor slab, energy during vibration propagation is consumed, and the effects of reducing vibration and reducing noise are achieved.
本发明涉及一种楼地面隔声砂浆及其制备方法，包括原料组分：水泥38‑42份、石粉40‑44份、骨料A20‑22份、骨料B8‑10份、骨料C10‑15份、胶粉1‑3份、纤维素醚0.1‑0.2份、纤维0.05‑0.15份、二氧化硅气凝胶0.4‑1份、瓜尔胶0.8‑0.15份，水上述干粉料总量的46.5‑46.8％；依次将胶粉、纤维素醚、纤维、二氧化硅气凝胶和瓜尔胶放到小型搅拌机单独搅拌，搅拌均匀完成后装入袋子，以上称之为预混小料；再将水泥、石粉、骨料A、骨料B、骨料C输送至滚筒式搅拌机，将预混小料输送至滚筒式搅拌机一起混合搅拌。本发明的砂浆凝结后具有弹性和纳米多孔网络结构，有效抑制楼板固态热传导，其网络孔隙内充满气态分散介质，撞击产生的振动会引起楼板内部介质的振动摩擦，消耗振动传播时的能量，起到减振降噪的作用。
