Wood magnesium board and preparation method thereof
The invention relates to the technical field of materials, and particularly discloses a wood magnesium board and a preparation method thereof. The wood magnesium board is prepared from the following raw materials in percentage by weight: 20-40% of magnesium oxide, 10-20% of a magnesium sulfate solution, 20-30% of wood flour, 0.2-0.3% of metal oxide, 3-4% of non-metal oxide, 1-2% of inorganic salt, 0.5-1% of acid, 0.1-0.5% of a waterproof agent and 1-2% of a modifier. The invention also discloses a preparation method of the wood magnesium board. The preparation method comprises the following steps: accurately metering raw materials; and conducting mixing, stirring, dispersing, metering and paving under a dry process, conducting pre-pressing, carrying out secondary hot press molding, conducting demolding, cutting and sanding in a short time, drying frame pieces, finally finely cutting and sanding a finished product, and packaging and delivering a finished product. The production cost is effectively reduced, the production period is shortened, and the plate is high in strength, good in toughness, environment-friendly and non-toxic.
本发明涉及材料技术领域，具体公开了一种木镁板及其制备方法。木镁板由如下重量百分含量的原料制备得到：20‑40％氧化镁、10‑20％硫酸镁溶液、20‑30％木粉、0.2‑0.3％金属氧化物、3‑4％非金属氧化物、1‑2％无机盐类、0.5‑1％酸类、0.1‑0.5％防水剂、1‑2％改性剂。同时公开了木镁板的制备方法，通过对原材料精确计量；在干法工艺下进行混合搅拌、分散、计量铺装，通过预压、二次热压成型，短时间内即可脱模、切割、砂光处理后，进行架片烘干，最终对成品进行精切割、砂光，即可打包出货。有效降低生产成本、缩短生产周期，同时板材强度高、韧性好、环保无毒。
