example 1

[0026] Diatomaceous earth and deionized water were evenly mixed at a mass ratio of 2:3 to obtain a slurry, which was allowed to stand for stratification, and the intermediate was collected and repeated twice. The intermediate was placed in an oven at 50° C. Treat diatomite; mix KH-550 and absolute ethanol uniformly at a volume ratio of 1:40 to obtain a mixed solution, soak the pretreated diatomite in the mixed solution, and let it stand in an oven at a temperature of 90°C for 4 hours. Suction filter to get the filter residue, wash 3 times with absolute ethanol to obtain the carrier; mix the zeolite and absolute ethanol uniformly according to the mass ratio of 1:10 to obtain a suspension, add the carrier according to the mass ratio of 1:5, and prepare the carrier at a temperature of 90°C Stand still in the oven for 4 hours, filter with suction to obtain a precipitate, wash with absolute ethanol 3 times to obtain a semi-finished product, dry the semi-finished product at 100°C to ...

[0028] Diatomaceous earth and deionized water were mixed evenly at a mass ratio of 2:3 to obtain a slurry, which was allowed to stand for layering, and the intermediate was collected and repeated twice. The intermediate was placed in an oven at 55° C. Treat diatomite; mix KH-550 and absolute ethanol uniformly at a volume ratio of 1:40 to obtain a mixed solution, soak the pretreated diatomite in the mixed solution, and let it stand in an oven at a temperature of 95°C for 4 hours. Suction filter to obtain filter residue, wash with absolute ethanol for 4 times to obtain carrier; mix zeolite and absolute ethanol uniformly at a mass ratio of 1:10 to obtain a suspension, add carrier at a mass ratio of 1:5, Stand in the oven for 4 hours, filter to get precipitate, wash with absolute ethanol 4 times to get semi-finished product, dry the semi-finished product at 105°C to constant weight, and heat up to 275°C for 5h at a heating rate of 1°C / min. Cool to room temperature to obtain the as...

[0030]Diatomaceous earth and deionized water were mixed evenly according to the mass ratio of 2:3 to obtain a slurry, which was left to stand for stratification, and the intermediate was collected. Repeated 3 times, the intermediate was placed in an oven at 60°C and dried to constant weight to obtain a pre- Treat diatomite; mix KH-550 and absolute ethanol uniformly at a volume ratio of 1:40 to obtain a mixed solution, soak the pretreated diatomite in the mixed solution, and let it stand in an oven at a temperature of 100°C for 5 hours. Suction filter to obtain filter residue, wash 5 times with absolute ethanol to obtain carrier; mix zeolite and absolute ethanol uniformly at a mass ratio of 1:10 to obtain a suspension, add carrier at a mass ratio of 1:5, Stand still in the oven for 5 hours, filter with suction to obtain a precipitate, wash with absolute ethanol for 5 times to obtain a semi-finished product, dry the semi-finished product at 110°C to constant weight, and heat up t...

Abstract

The invention relates to a preparation method of an ecological ceramic tile with a moisture regulating function, and belongs to the technical field of building materials. The preparation method is characterized in that zeolite is used as adsorption deposition liquid, diatomite is used as a matrix, the nanometer zeolite is assembled onto the diatomite by a laminating method under the action of electrostatic attraction, the amorphous silicon dioxide can be converted into the zeolite without destroying the morphology and structure of the diatomite, and the prepared product is composed of the nanometer zeolite and is rich in macropores, so as to improve the moisture absorbing and discharge speeds of the ceramic tile, shorten the moisture regulating balance time, and increase the moisture absorbing capacity. The preparation method has the advantages that in the adsorbing process of the ceramic tile, the capillary condensation occurs in the porous structure; in the moisture discharge process, the evaporation of water steam is closely related with the porous structure, and the moisture absorbing and discharge process of the ceramic tile is improved according to the saturation steam pressure of the concave liquid level in the pore and the saturation steam pressure of water in air; by using the diatomite as a sintering additive, the moisture absorbing function is realized.

Description

technical field [0001] The invention relates to a method for preparing ecological ceramic bricks with a humidity-regulating function, and belongs to the technical field of building materials. Background technique [0002] Excellent indoor environmental quality has always been what people yearn for and pursue, especially in modern society. Indoor air humidity directly affects human physical and mental health, storage of goods, heating energy consumption, etc. Therefore, it is of great significance to maintain an appropriate humidity range in the indoor environment. [0003] The current humidity control technology is mainly divided into two categories: active humidity control and passive humidity control. The active humidity control technology mainly realizes air humidity adjustment by consuming electric energy, which consumes a lot of energy, pollutes the environment, and is prone to building syndrome, which does not conform to the concept of green buildings. The passive h...
