Magnesite board and preparation method thereof
The invention relates to the field of materials, in particular to a magnesite board and a preparation method thereof.The magnesite board is prepared from, by weight, 60-75 parts of caustic-burned magnesia powder, 13-20 parts of anhydrous magnesium chloride, 5-15 parts of silica fume, 3-10 parts of chopped fibers and 0.1-2 parts of modifier; the chopped fibers are a mixture of carbon fibers, low-alkali glass fibers and basalt fibers, and the mass ratio of the carbon fibers to the low-alkali glass fibers to the basalt fibers is 10: (1-3): (1-3). The board has good strength and impact resistance, can be applied to substrates of ceiling boards, fireproof boards, partition boards, acoustic boards and the like, and can also be applied to other irregular boards with certain shapes like water meter wells.
本发明涉及材料领域，具体涉及一种菱镁板材及其制备方法，本发明所述菱镁板材由如下重量份的原料制备得到：轻烧镁粉60~75份，无水氯化镁13~20份，硅灰5~15份，短切纤维3~10份，改性剂0.1~2份；所述短切纤维为碳纤维、低碱玻璃纤维和玄武岩纤维的混合物，其质量比为碳纤维：低碱玻璃纤维：玄武岩纤维为10：1~3：1~3。本发明的板材具有很好的强度和抗冲击性能，可应用于天花吊顶板、防火板、隔墙板、吸音板等的基板，也可应用于其他像水表井一样具有一定形状的非规则板材。
