High-strength desulfurized gypsum block and preparation method thereof
The invention discloses a high-strength desulfurized gypsum building block and a preparation method thereof, and belongs to the technical field of building materials. The preparation method of the high-strength desulfurized gypsum building block comprises the following steps: (1) respectively grinding desulfurized building gypsum, steel slag, fly ash and slag, and controlling the particle size ofgrinding particles to be within a certain numerical value; (2) stir-frying the ground desulfurized building gypsum in a boiling and pressing kettle, and stirring while stir-frying; and (3) adding liquid paraffin into a water bath kettle, heating, adding an emulsifier into the heated liquid paraffin water bath kettle according to a ratio of 7: 23: 70, mixing, heating to melt, adding hot water withthe same temperature, uniformly stirring, carrying out thermal insulation cooling according to a preset time, and cooling to obtain the paraffin emulsion. The raw materials can be proportioned according to the characteristics of the desulfurized building gypsum, and the mechanical properties of the building block are improved in a targeted manner. By adding the paraffin emulsion, a layer of compact protective film is formed on the outer surface layer of the building block to resist the invasion of water.
一种高强脱硫石膏砌块及其制备方法，属于建筑材料技术领域。所述高强脱硫石膏砌块的制备方法，包括以下步骤：（1）将脱硫建筑石膏，钢渣，粉煤灰和矿渣分别进行粉磨，并将研磨颗粒粒径控制在一定数值内；（2）将粉磨好的脱硫建筑石膏放入煮压釜中进行炒制，边炒制边搅拌；（3）将液体石蜡加入到水浴锅中加热，加热后将乳化剂按7:23:70的配比加入到加热后的液体石蜡的水浴锅中，混合加热至融化，此时加入同等温度的热水搅拌均匀，根据预设时间进行保温冷却，冷却后制得石蜡乳液。本发明能够针对脱硫建筑石膏的特性实行原料配比，有针对的提高砌块力学性能。本发明通过加入石蜡乳液，使得砌块外表层形成一层致密的保护膜，抵御水的侵入。
