The invention discloses a mortar and a preparation method thereof. The mortar is prepared from cement, sand, cellulose ether, nano microspheres, superfine mineral powder, perlite powder, carbon fibers, desulfurized gypsum and a water reducing agent. Cellulose ether is added, so that the mortar system is more stable, the fluidity of the mortar in the stirring process and the smoothness of construction are also improved, meanwhile, water in the mortar is not prone to losing and is gradually released within a long period of time, and the mortar is endowed with a good water-retaining property andworkability. Nano microspheres are added, the size of the nano microspheres is small, thus the nano microspheres can be easily and uniformly painted, the heat conductivity coefficient of the nano microspheres can reach 0.07 W/m.K or below, and thus the nano microspheres have good heat preservation and insulation performance. The superfine mineral powder is added, and the fluidity of slurry can beimproved through the superfine mineral powder. The interface structure between cement and aggregate is improved, the strength and durability of concrete are improved, other effective components are matched, and finally the performance of the mortar is optimized.
一种砂浆及其制备方法，砂浆包括水泥、砂、纤维素醚、纳米微珠、超细矿粉、珍珠岩粉末、碳纤维、脱硫石膏和减水剂。本发明添加纤维素醚，使砂浆体系更稳定，也提高了砂浆在搅拌过程的流动性和施工的滑爽性，同时使砂浆中的水份不易失去，并在较长的一段时间内逐步释放，赋予砂浆良好的保水性和工作性；添加纳米微珠，纳米微珠颗粒小，容易涂抹均匀，其导热系数可以达到0.07W/m.K以下，具有很好的保温隔热性能；添加超细矿粉，超细矿粉可以提高浆体的流动性，改善水泥与骨料的界面结构，使混凝土的强度和耐久性得到提高，再配合其他有效组分，最终达到优化砂浆性能的目的。
