Problems solved by technology

[0002] As a building decoration material, natural sandstone has the following defects: 1. It is easy to be weathered and lost, which affects the appearance; 2. Poor anti-fouling property, easy to be contaminated with dust stains, and the contaminated dust stains are not easy to wash off, which affects the appearance of decorations; 3. Natural sandstone It is a non-renewable resource, its output is limited, and it is impossible to meet the needs of the modern decoration industry; and the mining of natural sandstone is very serious to the damage of the natural environment; 4. After the natural sandstone is mined, its cut surface is flat and its texture is sandy The adhesion is not good, which makes the installation very difficult; even if it is installed by dry hanging, it is easy to fall off due to loose sand particles; 5. The texture and color of natural sandstone are uncontrollable and jumpy, and it is difficult to meet the user's decoration requirements. 6. The cost of natural sandstone is high
However, the current composite sandstone slabs also have some shortcomings: the sandstone effect and texture are simple and rigid, the changes are not rich and natural, and the appearance effect of natural sandstone is not close enough.

Embodiment 1

[0027] A method for preparing a composite sandstone slab, comprising the following steps:

[0028] (1) Brush the sandy primer on the cement fiberboard, the thickness of the sandy primer layer is 30 μm; after 6 hours, evenly coat the first layer of sandstone on the sandy primer layer by the machine mold, the first layer The thickness of the sandstone layer is 1mm, and the surface of the sandstone layer is required to be smooth without unevenness;

[0029] (2) Spread the texture effect of the paint on the first layer of sandstone through a pre-made sandstone-effect screen. After the paint is completely dry, apply a layer of transparent pure acrylic emulsion. The thickness of the pure acrylic emulsion layer is 20μm;

[0030] (3) After the transparent pure acrylic emulsion is completely dry, scrape the second layer of sandstone. The thickness of the second layer of sandstone layer is 0.8mm. Use sandstone with high transparency and a particle size of 0.5-1mm to make the sandstone ...

Embodiment 2

[0032] A method for preparing a composite sandstone slab, comprising the following steps:

[0033] (1) Brush the sandy primer on the calcium silicate board, the thickness of the sandy primer layer is 10 μm; after 6 hours, evenly coat the first layer of sandstone on the sandy primer layer by the machine mold, the second The thickness of a layer of sandstone layer is 2mm, and the surface of the sandstone layer is required to be smooth and free of unevenness;

[0034] (2) Spread the texture effect on the first layer of sandstone through the pre-fabricated sandstone effect copper. After the paint is completely dry, spray a layer of transparent silicone acrylic emulsion. The thickness of the transparent silicone acrylic emulsion layer is 10μm;

[0035] (3) After the transparent pure acrylic emulsion dries up, scrape the second layer of sandstone. The thickness of the second layer of sandstone layer is 1mm. Use sandstone with high transparency and particle size of 0.5-1mm. It is s...

Embodiment 3

[0037] A method for preparing a composite sandstone slab, comprising the following steps:

[0038] (1) Brush the primer with sand on the ceramic slab, and the thickness of the primer layer with sand is 40 μm; after 6 hours, apply the first layer of sandstone evenly on the primer layer with sand by the machine mold, the first The thickness of the sandstone layer is 0.5mm, and the surface of the sandstone layer is required to be smooth and free of unevenness;

[0039] (2) Apply the texture effect on the first layer of sandstone through the pre-made sandstone-effect inkjet. After the ink is completely dry, roll on a layer of transparent styrene-acrylic emulsion. The thickness of the transparent styrene-acrylic emulsion layer 40μm;

[0040] (3) After the transparent pure acrylic emulsion is completely dry, scrape the second layer of sandstone. The thickness of the second layer of sandstone layer is 0.5mm. Use sandstone with high transparency and a particle size of 0.5-1mm to make...

Abstract

The invention discloses a composite sandstone board and a preparation method and application thereof. The composite sandstone board is sequentially formed by a blank bottom plate, a sand primer layer, a first sandstone layer, a texture cloth layer, a first transparent emulsion layer, a second sandstone layer and a second transparent emulsion layer. The composite sandstone board disclosed by the invention has strong soil resistance, is difficult to air-slake and is simple and convenient to install. Moreover, the composite sandstone board has natural texture and can reach the same decorative effect as natural sandstone. The defect that the natural sandstone has poor soil resistance and is easy to air-slake is overcome.
