The invention relates to a plant fiber cement board. The plant fiber cement board comprises, by weight, 70-85 parts of plant fibers, 3-6 parts of a reinforcing agent, 3-5 parts of a curing agent, 15-25 parts of an inorganic adhesive, 0.2-0.5 part of a preservative and 1-3.5 parts of a catalyst. The cement board has the following advantages: the content of the plant fibers in the cement board is high, and the utilization rate of forestry and agricultural residues is increased; the product taking the magnesium sulfate cement as the adhesive overcomes the defects of halogenation, condensation andmetal corrosion of a magnesium chloride product; after a modifier and an additive are added, the compressive strength and the breaking strength of the magnesium sulfate cement product are improved, and the water softening coefficient and the acid and alkali corrosion resistance are improved; the magnesium oxysulfate cement product taking the plant fibers as the main material has an obvious construction energy-saving advantage; and the volume weight of the product is reduced while the structural strength of the product is ensured, the requirements of light-weight and high-strength wall materials are met, the heat preservation and sound insulation effects of the product are improved, and the production cost is reduced.
本发明涉及一种植物纤维水泥板，包括如下重量份数的组份：植物纤维70‑85份，增强剂3‑6份，固化剂3‑5份，无机胶黏剂15‑25份，防腐剂0.2‑0.5份，催化剂1‑3.5份。本发明的优点：本发明的水泥板中植物纤维含量高，提高了农林废弃物的利用率。以硫镁水泥为胶黏剂的制品克服了氯镁制品返卤、结露、腐蚀金属弊端。添加改性剂和添加剂后提高了硫镁水泥制品的抗压、抗折强度，提高耐水软化系数、耐酸碱腐蚀性能；以植物纤维为主的硫氧镁水泥制品有明显的建造节能优势。在保证产品结构强度的同时，降低产品容重，实现轻质高强的墙体材料要求，增加了产品的保温、隔音效果，降低了生产成本。
