Diatom ceiling with humidity adjustment function, and preparation method thereof

The invention relates to a diatom ceiling with a humidity adjustment function, and a preparation method thereof. Current ceilings are prone to deformation after absorbing moisture, and have no humidity adjustment function. The invention mainly aims at solving the above problems. The diatom ceiling with the humidity adjustment function is composed of the raw materials of diatomite, a calcareous raw material and a fiber material with a mass ratio of 100:20-60:0.2-1.2. The mass of mixing water is 10-50% of the total mass of the above diatomite, calcareous raw material and fiber material. The invention also provides the preparation method of the diatom ceiling. The method comprises the specific steps of raw material preparation, roasting activation, material blending and well mixing, pressure molding, hydrothermal solidification, drying dehydration, and finished product treatment. The diatom ceiling provided by the invention has technical features of light weight and high strength. With the corresponding preparation method, water molecule large-capacity fast absorption and release are realized.
