Novel fireproof and waterproof magnesium oxide board and preparation process thereof
The invention discloses a novel fireproof and waterproof magnesium oxide board and a preparation process thereof. The fireproof and waterproof magnesium oxide board comprises the following componentsand contents: 20 to 30 percent of light calcined magnesia; 15-20% of anhydrous magnesium chloride; 35-50% of expanded vermiculite; 5-15% sodium silicate, and 1-3% of a waterproof agent; the raw materials are subjected to proportioning, pulping, plate making, dust removal and maintenance. The fireproof and waterproof magnesium oxide board is obtained. The novel fireproof and waterproof magnesium oxide board has good heat insulation effect, after the magnesium oxide board is integrally manufactured; integral structural stability, the overall heat insulation and flame retardance are high; quick ignition by flame is avoided, the overall fire protection effect is improved, the overall waterproof performance of the magnesium oxide board processed through the preparation process is high, the overall service life is prolonged, and the novel fireproof and waterproof magnesium oxide board is easy to manufacture, stable in structure, high in mechanical strength, low in density, non-toxic, harmless, high in fireproof grade, convenient to popularize and capable of improving the overall practicability.
本发明公开了一种新型防火防水氧化镁板及其制备工艺，该防火防水氧化镁板包括以下组分及含量：轻烧氧化镁20‑‑30%，无水氯化镁15—20%，膨胀蛭石35—50%，5—15%硅酸钠，1—3%防水剂，并将上述原料通过配料打浆、制板、除尘养护，从而得到一种防火防水氧化镁板，该新型防火防水氧化镁板及其制备工艺，具有良好的隔热效果，且整体制成氧化镁板后，整体的结构稳定性，整体的隔热阻燃性较强，不会被火焰快速点燃，增加了整体对火灾的保护效果，且通过该制备工艺加工出的氧化镁板整体的防水性较强，增加了整体的使用寿命，该新型防火防水氧化镁板制作简单，结构稳定，高机械强度，低密度，无毒无害，防火等级高，方便进行推广，增加了整体的实用性。
