Problems solved by technology

At present, there have been some introductions to the research on humidity-adjusting bricks in China, such as the Chinese invention patent "Preparation method of a humidity-regulating material" (publication number CN104527155A). The preparation method has higher requirements for production equipment
However, the Chinese invention patent "A Process for Preparing Breathing Bricks Using Polishing Waste Slag" (publication number CN104003755A) has a firing temperature as high as 900-1000°C. The production itself is a high-energy-consuming process, and at high temperatures, the porous structure of the material will deteriorate. Damaged to a certain extent, affecting the humidity control performance of the material

Embodiment 1-3

[0044] (1) Take sepiolite clay (sepiolite), glass powder and powder according to the mass percentage in Table 1, add water with 5% powder mass, and ball mill for 2 hours in a planetary ball mill to obtain a uniform mixture Powder;

[0045] (2) Add the mixed powder into the mould, cloth (pave) and press to form under 12MPa. Dry the green body in a blast drying oven according to the process of 40°C for 4 hours and 70°C for 2 hours, with a thickness of 5mm;

[0046] (3) Put the dried green body into a muffle furnace and fire it at 650° C. for 40 minutes.

[0047] The flexural strength of the intelligent humidity-adjusting bricks obtained in Examples 1-3 is shown in Table 1, and the flexural strength of the bricks tends to increase with the increase of the amount of glass powder added. Then wrap the intelligent humidity-adjusting brick with aluminum foil, and only expose the upper surface. Under the condition of 25°C, absorb and dehumidify in the environment of 90% and 36% humid...

Embodiment 4-6

[0051] (1), sepiolite clay and glass powder are weighed according to the mass percentage in Table 2, the main ingredient sepiolite: glass powder mass ratio is 4:1, add 10% water of powder quality, in the planetary formula Ball milling in a ball mill for 4 hours to obtain a uniform mixed powder;

[0052] (2) Add the mixed powder into the mould, cloth, press and form at 20MPa. Dry the green body in a blast drying oven according to the process of 40°C for 4 hours and 70°C for 2 hours, with a thickness of 5mm;

[0053] (3) Put the dried green body into a muffle furnace, and fire at 600°C, 700°C, and 800°C for 60 minutes.

[0054] The flexural strength of the intelligent humidity-adjusting brick obtained in this embodiment is shown in Table 2. As the firing temperature increases, the flexural strength of the brick tends to increase. Then wrap the intelligent humidity-adjusting brick with aluminum foil, and only expose the upper surface. Under the condition of 25°C, absorb and deh...

Abstract

The invention relates to an intelligent humidifying brick, which comprises a functional layer, wherein the functional layer is formed by firing sepiolite clay and glass powder as main raw materials, and the mass percent of the glass powder is 5-20 wt%.

Description

technical field [0001] The invention relates to an intelligent humidity-regulating brick and a preparation method thereof, in particular to a method for preparing an intelligent humidity-regulating brick with low-grade sepiolite clay as the main raw material and solid waste as an auxiliary material by low-temperature firing, which belongs to humidity-regulating Building materials field. Background technique [0002] According to the definition of a healthy residence by the World Health Organization (WHO), the relative humidity of indoor air should be kept between 40% and 70% all year round. Studies have shown that when the indoor humidity is lower than 30%, it will cause discomfort symptoms such as eyes, nose, throat, skin, etc., and aggravate the condition of asthma patients; when the humidity is higher than 70%, it will cause indoor mites to breed, and various bacteria, fungi, and viruses will survive. Time increases, affecting people's health. China is located in the te...
