Interior wall putty with moisture-regulating and moisture-proof function

Abstract

The invention relates to an internal wall putty with humidity-regulating and moistureproof functions, which is composed of the following components in parts by weight: 0.2-0.6 part of main humidity-regulating material, 10-35 parts of auxiliary humidity-regulating material, 20-30 parts of inorganic gel material, 20-50 parts of inorganic filler, 1-5 parts of organogel material, 0.8-2 parts of functional assistant and 0.5-3.5 parts of assistant. The main humidity-regulating material is high-polymer water-absorbing resin with the fineness of greater than 200 meshes. The functional assistant is microcrystalline cellulose with the fineness of greater than 300 meshes. The internal wall putty has the decoration function, and also has the humidity-regulating and moistureproof functions. The internal wall putty can effectively adsorb moisture in indoor air to achieve the moistureproof and moldproof effects, and can also relatively regulate the indoor air humidity to enhance the residence comfort. The product has the advantages of no pollution and zero VOC (volatile organic compound) release, can be used as a rough coat of the latex paint and can also be used as an interior decoration material independently.

Description

technical field [0001] The invention relates to an interior wall putty, in particular to an interior wall putty with the function of regulating humidity and preventing moisture. Background technique [0002] At present, the putty actually applied to interior wall decoration materials cannot effectively solve the following practical problems: 1. The problem of indoor moisture-proof technology in humid weather. The relative humidity of the indoor air is too high, and the walls are prone to mold, which is not good for health and affects the comfort of living. It is necessary to prevent moisture and reduce the relative humidity of the indoor air. 2. The technical problem of indoor humidity control in dry weather. The relative humidity of indoor air is too low, which is also unfavorable to health and affects the comfort of living. It is necessary to increase the relative humidity of indoor air by adding water. [0003] In the spring rainy season, especially in southern China an...

Problems solved by technology

[0002] At present, the putty actually applied to interior wall decoration materials cannot effectively solve the following practical problems: 1. Indoor moisture-proof technical problems in humid weather, the relative humidity of the indoor air is too high, and the walls are prone to mold, which is not good for health and affects the comfort of living. Moisture-proof is required to reduce the relative humidity of the indoor air

2. Technical problems of indoor humidity control in dry weather. The relative humidity of indoor air is too low, which is also unfavorable to health and affects the comfort of living. It is necessary to increase the relative humidity of indoor air by adding water.

[0006] In the published patent (CN101368014A), porous materials such as acid-treated diatomite, sepiolite, attapulgite, vermiculite, pumice powder, kaolin and bentonite are used as moisture-controlling and moisture-proof materials, which are subject to Certain restrictions: Because these moisture absorption and dehumidification data are laboratory data obtained under ideal conditions (incubator), the applicant of this application actually used the above-mentioned scheme in the indoor test of commercial houses, and found that the error is large, and the volume space is larger. Larger, the larger the error

Secondly, the scheme described in the above-mentioned published patent (CN101368014A) does not consider the construction and grinding properties of putty, and the actual construction is not ideal

Thirdly, the price of the above-mentioned porous materials is relatively high, and the amount of addition is high (≥50%). Due to the low whiteness, the putty made cannot be used as a finishing layer alone. If the surface is covered with latex paint, the test shows that the humidity control ability is significantly reduced
