Inorganic whisker reinforced basic magnesium sulfate foaming cement and preparation method thereof
The invention belongs to the field of building materials, and particularly relates to inorganic whisker reinforced basic magnesium sulfate foaming cement and a preparation method thereof. The whisker reinforced BMS foamed cement is prepared from the following raw material components in parts by weight: 600 to 700 parts of magnesium sulfate heptahydrate, 550 to 650 parts of active magnesium oxide, 5 to 10 parts of additive, 5 to 15 parts of foaming agent, 10 to 40 parts of basic magnesium sulfate whisker and 650 to 750 parts of water. The whiskers and the cement matrix are hydrate crystals of basic magnesium sulfate, so that the interfacial compatibility of the whiskers and the cement matrix is good, the whiskers can be uniformly dispersed in the foamed cement and are staggered with 5.1.7 phases of the matrix to form a network structure, and the mechanical property of the BMS foamed cement can be improved. The method has the advantages of being high in operability, good in repeatability, free of environmental pollution, capable of being carried out at normal temperature, easy to industrialize and the like; the prepared BMS foamed cement has the advantages of heat preservation, small density, high strength, good toughness and the like.
本发明属于建筑材料领域，具体涉及一种无机晶须增强碱式硫酸镁发泡水泥及其制备方法。该晶须增强BMS发泡水泥包括以下重量份的原料组分：七水硫酸镁600～700份，活性氧化镁550～650份，外加剂5～10份，发泡剂5～15份，碱式硫酸镁晶须10～40份，水650～750份。本发明所用晶须与水泥基体均为碱式硫酸镁的水合物晶体，因此它们的界面相容性良好，晶须能在发泡水泥中分散均匀，且与基体5·1·7相相互交错形成网络状结构，可提高BMS发泡水泥的力学性能。本发明具有可操作性强、重复性好、无环境污染、可在常温下进行、易于实现工业化等优势；所制备的BMS发泡水泥兼具保温性、密度小、强度高、韧性良好等优点。
