Magnesium silicate composite board and preparation method thereof
The invention discloses a magnesium silicate composite board and a preparation method thereof, and relates to the technical field of fireproof boards. The magnesium silicate composite board comprises the following raw materials in parts by mass: 10-40 parts of light calcined magnesia, 2-6 parts of magnesium carbonate, 10-20 parts of calcined coal gangue powder, 5-30 parts of ground power plant furnace bottom slag, 20-30 parts of granulated blast furnace slag powder, 20-40 parts of limestone powder, 15-25 parts of water, 2.2-11 parts of reinforced fibers and 0.01-0.5 part of sodium phosphate. The ground power plant furnace bottom slag and the granulated blast furnace slag powder are used for replacing silica fume to serve as a silicon source to prepare the magnesium silicate composite board, the production cost is low, harm to a human body is small in the preparation process, and the prepared magnesium silicate composite board has the advantages of being small in dry shrinkage, high in deformation resistance and good in durability; the problems that an existing magnesium silicate cement fireproof plate is large in dry shrinkage, prone to deformation, poor in durability and high in production cost are solved.
本发明公开了一种硅酸镁复合板材及其制备方法，涉及防火板材技术领域。本发明硅酸镁复合板材，包括以下质量份数的原料：轻烧氧化镁10～40份、碳酸镁2～6份、煅烧煤矸石粉10～20份、磨细电厂炉底渣5～30份、粒化高炉矿渣粉20～30份、石灰石粉20～40份、水15～25份、增强纤维2.2～11份和磷酸钠0.01～0.5份。本发明的以磨细电厂炉底渣和粒化高炉矿渣粉代替硅灰作为硅源制备硅酸镁复合板材，不仅生产成本低，制备过程对人体危害小，而且制得的硅酸镁复合板材具有干缩小、抗变形能力强和耐久性好的优点，解决了目前硅酸镁水泥防火板材干缩大、易变形、耐久性能差和生产成本高的问题。
