Magnesium-based thermal insulation fireproof material for buildings and preparation method thereof
The invention discloses a magnesium-based thermal insulation fireproof material for buildings and a preparation method thereof. According to the magnesium-based thermal insulation fireproof material for the buildings, magnesium oxide and magnesium chloride serve as main bodies, the material is light and high in hardness, the problems of efflorescence, frosting and whitening of the material in theinitial stage can be inhibited by adding the acid-proof agent, coal ash and magnesium oxide are industrial product waste and are used for the magnesium-based thermal insulation fireproof material, waste utilization is achieved, and the raw material cost is low; the additive is added, so that the finished product is good in water resistance, not prone to buckling deformation and free of hardened body spalling, in addition, crystal water in the magnesium chloride material is wrapped by the additive, and magnesium oxide crystal water loss is controlled through constant-temperature maintenance; the surface of the product is coated with water-based fireproof paint, and the overall performance of the product is further improved. Finally, the magnesium-based thermal insulation fireproof materialwhich is good in water resistance, not prone to buckling deformation, free of frosting and whitening and high in corrosion resistance and acid resistance is obtained, the preparation process is simple, and labor is saved during operation.
本发明公开了一种建筑用镁基保温防火材料及其制备方法。本发明的建筑用镁基保温防火材料以氧化镁、氯化镁作为主体，材料轻质硬度高，加入防酸剂可抑制材料在初期出现的返卤、泛霜起白问题，且粉煤灰、氧化镁均为工业产品废弃物，用于镁基保温防火材料实现了废弃物利用，原料成本较低；加入添加剂可使得成品耐水性好，不易翘曲变形、不硬化体胀裂，另外通过加入添加剂，将氯化镁材料内部结晶水包裹住，经恒温养护，控制氧化镁结晶水流失；产品表面涂上水性防火涂料，进一步提高产品整体性能。最终获得一种耐水性好、不易翘曲变形、无泛霜起白、耐腐蚀性能和抗酸性能强的镁基保温防火材料，制备工艺简单，操作节省人力。
