Abstract

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.

Description

technical field [0001] The invention relates to a porous lightweight building functional material, in particular to a diatom ceiling with a humidity regulating function and a preparation method thereof, belonging to the technical field of preparation of inorganic non-metallic materials. Background technique [0002] The indoor humid environment of residential buildings directly affects the thermal comfort and thermal sensation of the human body, and the most suitable humidity range for the human body is between 40-70%. The use of humidity-regulating materials to control and adjust humidity has a history of more than 20 years in Japan, and the technology is ahead of other countries. Especially in terms of mechanism research, it has a relatively advanced theoretical basis. Many humidity-regulating building materials and humidity-regulating coatings have formed markets. In the past 10 years, with the improvement of people's requirements for the quality of living environment, th...
