Low-water-absorption sound insulation mortar and preparation method thereof
The invention discloses low-water-absorption sound insulation mortar and a preparation method thereof. The mortar is mainly prepared from the following components in parts by weight: 20 to 25 parts of Portland cement, 30 to 45 parts of quartz sand, 8 to 15 parts of limestone powder, 3 to 6 parts of fluorinated graphene, 0.1 to 0.2 part of porous rubber powder, 3 to 8 parts of silicon dioxide aerogel, 8 to 15 parts of basalt chopped fiber, 0.2 to 0.4 part of polycarboxylate superplasticizer, 8 to 15 parts of stabilizer and 0.1 to 0.3 part of retarder, the fluorinated graphene has a folded sphere-like structure, the spherical size is 0.5-10 [mu] m, the fluorocarbon ratio is 0.5-1.2, and the specific surface area is 350-520 m < 2 >/g. The fluorinated graphene and the silicon dioxide aerogel are introduced into the mortar compatibility, the fluorinated graphene can greatly improve the low water absorption performance of the sound insulation mortar, the silicon dioxide aerogel ensures the sound insulation function of the mortar, and the requirements of specific buildings for the low water absorption performance, the sound insulation performance and the like can be met.
本发明公开了一种低吸水率隔音砂浆及其制备方法，其中，该砂浆主要由以下重量份数的组分配制而成：硅酸盐水泥20～25份、石英砂30～45份、石灰石粉8～15份、氟化石墨烯3～6份、多孔橡胶粉0.1～0.2份、二氧化硅气凝胶3～8份、玄武岩短切纤维8～15份、聚羧酸减水剂0.2～0.4份、稳定剂8～15份和缓凝剂0.1～0.3份；所述氟化石墨烯具有褶皱类球形结构，球形尺寸为0.5～10μm，氟碳比为0.5～1.2，比表面积为350～520m2/g。本发明的砂浆配伍中引入了氟化石墨烯和二氧化硅气凝胶，氟化石墨烯能极大提升隔音砂浆的低吸水率性能，二氧化硅气凝胶则确保了砂浆的隔音功能，能够满足特定建筑物对低吸水率、隔音等性能的要求。
