The invention relates to the technical field of building materials, in particular to a cement fiberboard. The cement fiberboard comprises the following components in parts by weight: 64-80 parts of brucite, 3-6 parts of magnesium chloride, 13-18 parts of magnesium sulfate, 8-15 parts of montmorillonite and 3-8 parts of an adhesive. According to the cement fiberboard disclosed by the invention, thebrucite is used for replacing fly ash; in a fumigation stage, the hydrophobicity of the cured coating is improved by using 5% vaporized diethyl ether; the finally prepared cement fiberboard has extremely low water absorptivity, and the water absorptivity is 20% or below, so that the toughness of the board placed for a long time cannot be reduced even in a high-humidity environment, cracks and thelike cannot be generated in actual use, and the cement fiberboard is simple in preparation process, convenient to construct and capable of being widely applied to production and life.
本发明涉及建筑材料技术领域，具体涉及到一种水泥纤维板。一种水泥纤维板，按重量份计，包括水镁石64‑80份、氯化镁3‑6份、硫酸镁13‑18份、蒙脱石8‑15份、胶黏剂3‑8份。本发明的水泥纤维板采用水镁石替代了粉煤灰，并在熏蒸阶段，用5％的汽化乙醚增加固化包衣的疏水性，最终制备得到的水泥纤维板具有极低的吸水性，吸水率在20％以下，因此，即使在高湿度环境下，长期放置板材韧性亦不会降低，在实际使用中不会产生裂痕等情况，且产品制备工艺简单，施工方便能被广泛应用与生产和生活中。
