Fireproof base material plate and preparation method thereof
The invention provides a fireproof base material plate which is characterized by comprising magnesium oxide, brine, water, additives, colloid and wood flour; magnesium oxide, brine and water form gelof a ternary system, and brine is a neutral mixture formed by proportioning magnesium chloride and magnesium sulfate. According to the invention, magnesium chloride (alkaline) and magnesium sulfate (acidic) are scientifically proportioned to form mixed brine (neutral), so that the problem of board efflorescence is solved; meanwhile, the invention provides a preparation method of the fireproof basematerial plate, a sectional type hot pressing process is adopted to ensure that the plate does not crack or bulge, the plate forming time is shortened, and the breaking strength is improved.
本发明提供一种防火基材板，其特征在于，包括：氧化镁、卤水、水、添加剂、胶体、木粉，所述氧化镁、卤水、水形成三元体系的凝胶，卤水为氯化镁和硫酸镁经过配比形成的中性混合物。本发明采用氯化镁（碱性）和硫酸镁（酸性）经科学配比成混合卤水（中性）克服了板材返卤的问题；同时本发明提供一种防火基材板的制备方法，采用分段式热压工艺保证板材不裂开不起鼓，同时缩短板材成型时间，提高抗折强度。
