Embodiment approach

[0021] According to a preferred embodiment of the present invention, the putty powder includes the following raw material components in weight ratio:

[0022]

[0023] In a further preferred embodiment, the putty powder includes the following raw material components in weight ratio:

[0024]

[0025] Among them, diatomaceous earth putty powder is used, which has the function of regulating humidity. When the indoor humidity rises, the ultra-fine pores on the diatomite wall material can automatically absorb the moisture in the air and store it. If the moisture in the indoor air decreases and the humidity drops, diatomaceous earth is able to release the moisture stored in the ultra-fine pores.

[0026] Diatomite has the characteristics of large porosity, strong absorption, stable chemical properties, wear resistance and heat resistance. It is a natural material that is a potential development in China. It does not contain harmful chemicals. In addition to its characterist...

Embodiment 1

[0210] The preparation of embodiment 1 modified nano-titanium dioxide / diatomite composite

[0211] Take 15mL of tetrabutyl titanate, 75mL of absolute ethanol, 7.5mL of distilled water and 1.5mL of acetic acid, stir and mix tetrabutyl titanate and absolute ethanol, then add acetic acid dropwise, and then slowly add distilled water dropwise to form TiO 2 Precursor gel, prepare multiple copies and store them for later use;

[0212] Weigh 30 g of diatomite powder, 0.67 g of polyvinyl alcohol, and the TiO prepared above 2 Precursor gel 5g, add an appropriate amount of water to the three, stir and mix well, put it in a high-pressure reactor, and react at 150°C for 12 hours under magnetic stirring to obtain a mixed solution;

[0213] The mixed solution was dried at 60°C and placed in a nitrogen atmosphere furnace, and kept at 650°C for 2 hours to obtain a modified nano-titanium dioxide / diatomite composite.

Embodiment 2

[0214] Embodiment 2 Preparation of modified nano-titanium dioxide / diatomite composite

[0215] Take 6 mL of tetrabutyl titanate, 75 mL of absolute ethanol, 10 mL of distilled water and 5 mL of acetic acid, stir and mix tetrabutyl titanate and absolute ethanol, then add acetic acid dropwise, and then slowly add distilled water dropwise to form TiO 2 Precursor gel, preparation of multiple TiO 2 The precursor gel is placed for use;

[0216] Weigh 30 g of diatomite powder, 0.88 g of polyvinyl alcohol, and the TiO prepared above 2 3.5 parts of precursor gel, add appropriate amount of water to the three, stir and mix them evenly, put them in a high-pressure reactor, and react at 150°C for 12 hours under magnetic stirring to obtain a mixed solution;

[0217]The mixed solution was dried at 60°C and placed in a nitrogen atmosphere furnace, and kept at 650°C for 2 hours to obtain a modified nano-titanium dioxide / diatomite composite.

Abstract

The invention discloses a coating construction technology for an indoor wall. Kieselguhr putty powder with a humidifying function is combined with a water-based inorganic coating with air permeability, and an appropriate construction technology is adopted for coating the indoor wall, so that the requirement for indoor wall decoration can be met, absorbability and air permeability of the wall are promoted and the wall has the function of regulating indoor air humidity.

Description

technical field [0001] The invention relates to the field of coating, in particular to a coating construction process for indoor walls. Background technique [0002] At present, when the interior wall is painted, due to the traditional construction technology of putty and latex paint, the adsorption and air permeability of the wall surface are not ideal. When the moisture content of the wall is too high, it is easy to cause mildew on the coating. Change, hollowing, shedding and other phenomena; at the same time, it cannot adjust the indoor air humidity to improve the indoor living environment. [0003] However, although the putty powder added with diatomaceous earth has the function of regulating air humidity, it is scraped on the wall as a decorative layer alone, and the effect is not ideal. It has poor water resistance, poor scrub resistance, low strength, easy to powder off, poor surface effect, not smooth and delicate enough. Although water-based inorganic silicate pai...
