Embodiment 1

[0030] A soft tile for building exterior wall, the preparation method is:

[0031] (1) Preparation of modifier: ethanol was added dropwise to 3ml of 30wt% phenyltriethoxysilane solution at a stirring speed of 800r / min, the concentration of which was changed to 20wt%, and 0.75 wt% was added dropwise within 5min. ml catalyst tetraethylammonium hydroxide, then 15mL of phenyltriethoxysilane was added dropwise to it at a rate of 2mL / min. After the dropwise addition, the stirring was carried out at room temperature for 5h, and then stirred in a water bath at 80°C for 10h. , heated to reflux for 24h to obtain a homogeneous transparent solution, the ethanol solvent was volatilized to obtain a lime milky product, the product was washed with a mixture of tetrahydrofuran and methanol, washed twice with distilled water, centrifuged, and freeze-dried to obtain a white solid powder. Polyhexahedral cage silsesquioxane;

[0032] (2) Mix 10g of sepiolite, diatomite and attapulgite in a ratio ...

Embodiment 2

[0048] The difference between this example and Example 1 is that the sepiolite is replaced by bentonite. Both 10g of raw materials in step (2) are 9g of bentonite and 1g of attapulgite, and the rest of the preparation steps are the same as in Example 1.

Embodiment 3

[0050] The difference between this example and Example 1 is that the modifier adopts acrylic emulsion, and the rest are the same as those in Example 1.

Abstract

The invention relates to a soft porcelain material and a preparation method thereof. The preparation method comprises the following steps: (1) preparing a modifier; (2) preparing a composite sepiolitematerial; (3) preparing a soft porcelain material, and crushing the composite sepiolite material to 15000 to 20000. In terms of material selection, a sepiolite-based composite adsorbent with an extremely large adsorption area is selected, an extremely strong adsorption effect on pollutants in air is achieved, and the composite sepiolite material is crushed and ground to 15000-20000 meshes, so that the composite sepiolite material has an extremely large adsorption surface area and can enhance the effect at the same time. By modifying the composite adsorbent, due to the fact that the diaminopropyl octamer hexahedral polyhedral silsesquioxane carries more negative charges, the composite adsorbent has an excellent adsorption effect on trace harmful organic gas in air.

Description

technical field [0001] The invention relates to a soft tile for building exterior walls and a construction method thereof, belonging to the field of building materials and construction. Background technique [0002] Soft porcelain is a new type of flexible surface decoration material, which is obtained by forming water-based polymer emulsion and inorganic substances such as cement, soil, quartz sand or mineral powder. It is an ecological and environmental protection building material. The appearance of soft porcelain is similar to that of ceramics, but it lacks the cold, heavy and fragile texture of traditional ceramic materials. Low cost, convenient construction, suitable for building decoration such as exterior walls, interior walls and ground, which greatly enriches and beautifies people's living and working environment. [0003] With the development of technology, people have successively developed a wide variety of soft porcelain, such as imitation stone, imitation lea...
