Lightweight magnesium oxysulfate cement material and preparation method thereof
The invention relates to the field of building wall material products, in particular to a light magnesium oxysulfate cement material and a preparation method thereof, and the raw materials comprise light calcined magnesia, magnesium sulfate heptahydrate, water, a modifier, an active filling material, an inert filling material, a foaming agent and a foam stabilizer. The preparation method comprises the following steps: firstly, respectively preparing a mixed solution A (comprising magnesium sulfate heptahydrate, water and the modifier) and a dry mixture B (comprising magnesium oxide, the active filler and the inert filler), and mixing and uniformly stirring the mixed solution A and the dry mixture B; then prefabricating foam, adding the prepared foam into the slurry, and uniformly stirring; and finally forming, demolding and maintaining. The method has the characteristics of waste resource utilization, energy conservation, environmental protection, simple production process, low cost and the like, the volume density of the prepared magnesium oxysulfate cement is 0.69-0.99 g/cm < 3 >, and the 28d compressive strength is 4.5-15.0 MPa.
本发明涉及建筑墙体材料制品领域，尤其涉及一种轻质硫氧镁水泥材料及其制备方法，其原料为：轻烧氧化镁、七水硫酸镁、水、改性剂、活性填充材料、惰性填充材料、发泡剂、稳泡剂。其制备方法为：首先分别制备混合溶液A(包括七水硫酸镁、水、改性剂)和干混合物B(包括氧化镁、活性填料、惰性填料)，将二者混合并搅拌均匀；然后预制泡沫，将所制泡沫加入上述料浆中，搅拌均匀；最后成型、脱模、养护。本发明具有废弃物资源利用、节能环保、生产工艺简单、成本低廉等特点，所制备的硫氧镁水泥体积密度为0.69～0.99g/cm3，28d的抗压强度为4.5～15.0MPa。
