Problems solved by technology

[0002] Excessive humidity in the air can cause discomfort such as dampness and chest tightness, and induce arthritis and other diseases. At the same time, it encourages the proliferation and development of various mold viruses and affects food processing and preservation.
However, if the air humidity is too low, it will cause skin allergies, dry eyes and nose, and reduce the resistance of the respiratory system, which is not conducive to health.
[0003] At present, people in the domestic industry have been researching and developing humidity-regulating building materials that can automatically adjust indoor humidity. For details, see patent number ZL200810017527. Less ideal, the moisture absorption and desorption speed is slower and the moisture absorption and desorption effect is less obvious

preparation example Construction

[0014] The preparation process of lithium chloride sol of the present invention is as follows:

[0015] It is prepared by mixing 10% LiCl with 90% polyacrylic superabsorbent resin sol. The polyacrylic acid superabsorbent resin sol is made by mixing superabsorbent resin and distilled water at a ratio of 1:99 (mass ratio).

Embodiment 1

[0023] The invention can be made into viscous and uniform slurry and applied to the automatic adjustment of the humidity in the house.

[0024] (1) Material preparation: Prepare the raw materials needed for production.

[0025] (2) Ingredients: 40 parts of building gypsum, 10 parts of plant fiber, 8 parts of lithium chloride sol, 3 parts of gypsum retarder, and 11 parts of white Portland cement clinker.

[0026] (3) Stirring: Add the above ingredients into a small mixer and stir for 5-10 minutes, then add water and stir for 10-20 minutes to make a thick and uniform slurry.

[0027] (4) Painting: The construction process is as follows: base treatment - paste cakes on the wall - evenly sprinkle water on the wall - prepare slurry (composite humidity-adjusting wall material) - scrape the slurry on the wall - scrape flat - compact and calender -Inspection and acceptance. When scraping and plastering the wall with Dehe humidity-adjusting building materials, first use 5mm thick pla...

Embodiment 2

[0028] Embodiment 2: The present invention can be made into a viscous and uniform slurry that is applied to the automatic regulation of humidity in the dwelling.

[0029] (1) with embodiment 1

[0030] (2) Ingredients: 40 parts of building gypsum, 10 parts of plant fiber, 8 parts of lithium chloride sol, 3 parts of gypsum retarder, 11 parts of white Portland cement clinker, 0.1 part of woody powder and 0.1 part of Meat brown scale ring handle mushroom powder.

[0031] (3) with embodiment 1

[0032] (4) with embodiment 1

[0033] In this embodiment, the humidity control effect of the present invention is greatly improved by adding the woody powder and the powder of the sarcocarpus. On the cement board, after drying, the moisture absorption and desorption effect of a wall painted with the finished product made in this embodiment is obviously better than that of the other wall. After testing, the finished product in this embodiment absorbs 5% more water than the other wall. A...

Abstract

The invention discloses a humidity-adjusting building material capable of automatically adjusting indoor humidity. The building material contains the following raw materials in parts by weight: 40 parts of building gypsum plaster, 10 parts of plant fibers, 8 parts of lithium chloride sol, 3 parts of a gypsum retarder and 11 parts of white Portland cement clinker, wherein a chemical component of the building gypsum plaster refers to a powder cementing material with Beta semi-hydrated gypsum as a main component and the powder cementing material is not pre-added with any admixture; the molecular formula of the Beta semi-hydrated gypsum is Beta CaSO4.1 / 2H2O; the lithium chloride sol consists of the following raw materials in percentages by weight: 10% of LiCl and 90% of acrylic acid series super-absorbent resin sol; the plant fibers refer to reed powder which is formed by grinding reeds. Compared with the prior art, the building material is remarkable in humidity adjusting effect and high in humidity absorbing-releasing speed. Compared with the relative humidity in rooms made from other materials, the relative humidity in a room made from the building material is averagely lowered by about 10%.

Description

technical field [0001] The invention relates to a humidity-adjusting building material capable of automatically adjusting indoor humidity. Background technique [0002] Excessive moisture content in the air can cause discomfort such as dampness and chest tightness, and induce arthritis and other diseases. At the same time, it encourages the proliferation and development of various mold viruses and affects food processing and preservation. However, if the air humidity is too low, it will cause skin allergies, dry eyes and nose, and reduce the resistance of the respiratory system, which is not conducive to health. [0003] At present, people in the domestic industry have been researching and developing humidity-regulating building materials that can automatically adjust indoor humidity. For details, see patent number ZL200810017527. Less ideal, the moisture absorption and desorption speed is slower and the moisture absorption and desorption effect is less obvious. Contents ...
