Gypsum-based self-leveling mortar and preparation method thereof
The invention discloses gypsum-based self-leveling mortar and a preparation method thereof, belongs to the technical field of building materials, and solves the problem of rapid self-leveling of mortar, and the technical scheme is characterized in that the gypsum-based self-leveling mortar is prepared by weighing ingredients through full-automatic metering equipment, rapidly stirring through a double-shaft zero-gravity mixer, stirring powder materials for 5 minutes at first, and then stirring the powder materials for 5 minutes; the temperature of the raw materials is not higher than 50 DEG C, and the raw materials are prepared from desulfurized gypsum powder, PO425 cement, 40-70 parts of sand, a water reducing agent, a plastic expanding agent, a defoaming agent and a retarder, so that the requirements of JC/T1023-2007 gypsum-based self-leveling mortar are met, and the multi-aspect application range can be widened.
本发明公开了一种石膏基自流平砂浆以及制备方法，属于建筑材料技术领域，解决了砂浆的快速自流平问题，其技术方案要点是通过全自动计量设备称重配料，通过双轴无重力混合机进行快速搅拌，粉体材料先行搅拌5分钟，搅拌是原材料温度不高于50度，以脱硫石膏粉、PO425水泥、40‑70沙子、减水剂、塑性膨胀剂、消泡剂、缓凝剂配置而成，达到了满足JC/T1023‑2007《石膏基自流平砂浆》的要求的同时能够提高多方面适用范围。
