Description

Technical Field

[0001] This invention relates to the field of artistic coatings technology, and in particular to an artistic coating with a gradient rock slab effect, as well as its preparation and application methods. Background Technology

[0002] Currently, sintered stone slabs used in interior decoration are generally made from natural stone powder, feldspar, and other raw materials through a special sintering and pressing process. They possess advantages such as high hardness, good stain resistance, and rich textures. However, they have high requirements for the substrate and space in which they are applied, making them difficult to use on irregular surfaces, uneven walls, or in small spaces. To address the decorative issues of achieving a sintered stone effect in these scenarios, some multi-colored paints imitating the sintered stone effect have emerged. These multi-colored paints are mainly sprayed, which can indeed solve the construction problems in these scenarios. However, multi-colored paints imitate the color effect of stone by using colored dots, failing to replicate the color texture and gradient effect of sintered stone. Furthermore, ordinary thick-paste products, by mixing different colors and then splicing them together to create varying shades to achieve a gradient effect, produce a very stiff effect; the color gradient is not realistic enough. If the same color is mixed, the overall color difference after paint application is minimal, regardless of the thickness of the application, resulting in very little color variation and failing to create a gradient effect.

[0003] Therefore, there is an urgent need to develop a water-based coating that is easy to apply and suitable for various structural substrates, creating a realistic gradient rock slab effect. Summary of the Invention

[0004] To address the aforementioned problems, this invention provides an artistic coating with a gradient rock slab effect, as well as its preparation and application methods.

[0009] Furthermore, the preparation method of the sintered glass microspheres includes the following process: sintering glass microspheres coated with white pigment and inorganic resin at a temperature of 500-700℃.

[0010] Furthermore, the glass microspheres are borosilicate microspheres with a particle size of 50-120 μm; the white pigment is TiO2 with a particle size of 0.3-0.5 μm; the inorganic resin includes at least one of phosphate and silicate; preferably, the silicate may include sodium silicate, etc.

[0011] Furthermore, the fluff powder is white polyurethane elastic microspheres with a particle size of 10-100 μm; the glass powder has a particle size of 1000-2000 mesh.

[0012] Furthermore, the matte powder includes at least one of fumed silica and diatomaceous earth; the filler includes at least one of heavy calcium carbonate, calcined kaolin, wollastonite and barium sulfate.

[0013] Further, the cellulose is hydroxyethyl cellulose; the thixotropic anti-settling agent includes at least one of bentonite, attapulgite, and heteropolysaccharide derivatives; the thickener is an alkali-swellable thickener; and the emulsion includes at least one of pure acrylic emulsion and styrene-acrylic emulsion.

[0014] Secondly, the present invention provides a method for preparing the artistic coating with a gradient rock slab effect as described in any one of the first aspects, the preparation method comprising the following steps:

[0015] Water, dispersant, wetting agent, antifreeze, and film-forming aid are mixed evenly, and then cellulose, thixotropic antisettling agent, pH adjuster, and defoamer are added to obtain the first mixture;

[0016] Add filler, matting powder and glass powder to the first mixture and mix evenly to obtain the second mixture;

[0017] Emulsion is added to the second mixture and mixed evenly. Then, fluff powder, sintered glass powder, preservative and mildew inhibitor are added to obtain the art coating with gradient rock slab effect.

[0018] Secondly, the present invention provides a method for applying the artistic coating with a gradient rock slab effect as described in any one of the first aspects, the method comprising the following steps:

[0019] Step (1): According to the preset color effect of the paint, the art paint with gradient rock slab effect is mixed with composite color paste product to obtain the material;

[0020] Step (2): Apply the material in strokes along the pre-set texture using a putty knife, with the gap between each stroke being the width of the second coat. Smooth the artistic paint along the texture and let it dry.

[0023] Furthermore, the composite color paste product is based on commercially available conventional color pastes (such as Clariant's Colanyl series) with the addition of emulsion-containing base materials, which is equivalent to diluting ordinary color pastes, making it easier to add color pastes.

[0024] The technical solutions provided in the embodiments of the present invention have at least the following advantages compared with the prior art:

[0025] This invention provides an artistic coating with a gradient slab effect, along with its preparation and application methods. By incorporating sintered glass microspheres, the surface of which has an inorganic glaze layer with excellent hydrophobicity, the surface tension of the sintered microspheres is very low in the water-based coating system, preventing them from being wetted and colored by pigments. After the paint film dries, the overall color is the color of the pigment mixture, but uncolored white sintered microspheres can still be seen in certain areas. Areas with a higher concentration of white sintered microspheres appear whiter. Different artistic effects can be created by combining various application and plasticity methods. Simultaneously, in conjunction with other components, a water-based artistic coating is produced that combines natural color, realistic effect, seamless construction, and simple application to various structural substrates to achieve a gradient slab effect, better meeting consumer needs and application requirements. Specifically:

[0026] (1) The gradient rock slab effect is realistic, seamless, and can be applied to heterogeneous and non-flat surfaces.

[0027] (2) By mixing a single color, different shades of color can be created through construction techniques, resulting in a very natural slab effect.

[0028] (3) The product is easy to install, has high environmental performance, high hardness, and good feel. Attached Figure Description

[0059] Secondly, based on the same inventive concept, this invention provides a method for preparing the artistic coating with a gradient rock slab effect as described in any of the first aspects, such as... Figure 1 As shown, the preparation method includes the following steps:

[0060] Water, dispersant, wetting agent, antifreeze, and film-forming aid are mixed evenly, and then cellulose, thixotropic antisettling agent, pH adjuster, and defoamer are added to obtain the first mixture;

[0061] Add filler, matting powder and glass powder to the first mixture and mix evenly to obtain the second mixture;

[0067] Step (2): Apply the material in strokes along the pre-set texture using a putty knife, with the gap between each stroke being the width of the second coat. Smooth the artistic paint along the texture and let it dry.
