Building floor light-weight heat-preservation sound-insulation self-leveling mortar and preparation method thereof
The invention relates to the technical field of mortar, in particular to building floor light heat preservation and sound insulation self-leveling mortar and a preparation method thereof, and the building floor light heat preservation and sound insulation self-leveling mortar comprises the following raw materials: Portland cement, modified polypropylene fibers, fly ash, river sand, a water reducing agent, a defoaming agent, hollow glass beads and water. The modified polypropylene fiber is added, and calcium carbonate particles are uniformly deposited on the fiber surface by using calcium chloride and a sodium carbonate solution, so that on one hand, the roughness of the fiber surface is improved, on the other hand, the hydrophilicity of the fiber is also improved, the fiber can be uniformly dispersed in mortar, and the strength of the mortar can be improved; the polypropylene fibers are subjected to oil removal and swelling treatment firstly, so that subsequent calcium carbonate can be uniformly deposited and attached to the surfaces of the polypropylene fibers, and a positive effect on improvement of mortar performance is achieved.
本发明涉及砂浆技术领域，具体为一种楼地面轻质保温隔声自流平砂浆及其制备方法，包括以下原料：硅酸盐水泥、改性聚丙烯纤维、粉煤灰、河砂、减水剂、消泡剂、空心玻璃微珠、水。本发明通过加入改性聚丙烯纤维，利用氯化钙和碳酸钠溶液在纤维表面上均匀的沉积碳酸钙颗粒，一方面提高了纤维表面的粗糙度，另一方面也改善了纤维的亲水性，有利于其均匀分散于砂浆中，从而可以改善砂浆的强度；先对聚丙烯纤维进行除油和润胀处理，有利于后续碳酸钙均匀沉积附着在聚丙烯纤维的表面，对砂浆性能的改善起到积极作用。
