Technical Field
[0001] The present application belongs to the field of coatings and relates to a water-based multi-colored architectural coating. Background Art
[0002] Water-based multi-color architectural coating is a product specially designed to meet the growing market of building exterior wall coatings. This coating is made of high-tech modified resin and stable pigments. It is a fully water-based, one-time spray-applied multi-color granite coating. The colors it produces are more realistic, more durable, and colorful. Special colors can be provided on request, and the simulation is extremely high. There are no restrictions on its design, and the shape can be changed arbitrarily according to the designer's intention.
[0003] Patent CN204754017U discloses a colorful granite paint coating structure, including an exterior wall base layer, which is coated with an exterior wall putty layer, a primer layer, a textured paint layer, a smooth putty layer, a topcoat layer, and a finishing paint layer in sequence. The exterior wall putty layer is a flexible anti-cracking putty layer, the primer layer is an alcohol-soluble inorganic zinc-rich primer layer, the textured paint layer is an exterior wall multi-layer textured paint layer, the smooth putty layer is a water-based smooth putty layer, the topcoat layer is a water-in-water colorful coating, and the finishing paint is a polyphenylene sulfide epoxy composite heat-resistant and anti-corrosion coating.
[0004] In order to make the granite paint coating have a granular feel, particles of different sizes and colors are mixed into the granite paint to simulate the natural appearance of granite. These particles make the surface of the paint layer appear rough and rustic, and also enhance its three-dimensional and layered sense.
[0005] However, the construction of granite paint requires a high level of experience from the construction workers and is difficult. Particles are prone to large-scale movement, resulting in dense particles in some areas of the coating and no particles in other areas, affecting the quality of the coating. Utility Model Content
[0006] In order to ensure the quality of the coating while reducing the construction difficulty of construction workers, the present application provides a water-based colorful building coating.
[0007] The present application provides a water-based multi-color architectural coating that adopts the following technical solution:
[0008] A water-based multi-color building coating comprises a base layer, a middle layer and a surface layer, wherein the middle layer comprises a granite texture paint layer arranged between the base layer and the surface layer, the granite texture paint layer has a limiting net, the limiting net has a plurality of grids, aggregates are arranged in the grids, and the aggregates are fixedly connected to the grids by resin.
[0009] By adopting the above technical solution, the base layer of the coating is painted on the base layer, and the middle layer is arranged on the base layer. Since the middle layer of the granite texture paint layer has a limiting net, the aggregate can be limited, reducing the risk of large-scale movement of the aggregate under gravity or external construction force during construction, ensuring the overall quality of the coating, and reducing the construction difficulty of construction personnel.
[0010] Preferably, the limiting net includes an inner net and an outer net, the inner net is close to the base layer, the inner net includes a plurality of warp fiber bundles and weft fiber bundles, the warp fiber bundles and weft fiber bundles are staggered to form a grid, and the outer net is close to the surface layer, the outer net includes a plurality of warp fiber sleeves and weft fiber sleeves, the warp fiber sleeves and weft fiber sleeves are staggered to form a grid.
[0011] By adopting the above technical solution, the elasticity of the fiber sleeve is better than that of the fiber bundle, and the strength of the fiber bundle is better than that of the fiber sleeve. During construction, the aggregate can easily cause the outer net to undergo elastic deformation and move toward the inner net. The outer net plays a more guiding role, and the inner net has better strength and can be pressed tightly against the aggregate, thereby reducing the risk of large-scale movement of the aggregate.
[0012] Preferably, the warp fiber bundle and the weft fiber bundle are both glass fiber bundles, and the glass fiber bundle comprises a glass fiber core and a protective tube. There are at least two glass fiber cores, and the glass fiber cores are twisted with each other and arranged in the protective tube.
[0013] By adopting the above technical solution, the glass fiber bundle has multiple glass fiber cores twisted with each other, which can improve the strength of the glass fiber bundle. The glass fiber core is provided with a protective tube outside, which can reduce the risk of the glass fiber core being affected by the outside world.
[0014] Preferably, the protective tube is a polyvinyl chloride sleeve, and the warp fiber sleeve and the weft fiber sleeve are both glass fiber sleeves.
[0015] By adopting the above technical solution, the protective tube is a polyvinyl chloride sleeve, which has good compatibility with the resin and can improve the overall strength of the granite texture paint layer.
[0016] Preferably, the surface layer includes two layers of silicone-acrylic topcoat and a smooth putty layer, the smooth putty layer is arranged on the surface of the middle layer, and the two layers of silicone-acrylic topcoat are arranged on the surface of the smooth putty layer.
[0017] By adopting the above technical solution, two coats of silicone acrylic topcoat can ensure that the exterior wall will not turn white when exposed to long-term rain, will not turn yellow or fade when exposed to ultraviolet rays, thereby further improving durability.
[0018] Preferably, the surface of the smooth putty layer is provided with warp water-sensitive dye patterns and weft water-sensitive dye patterns, the warp water-sensitive dye patterns are aligned with the warp fiber sleeves, and the weft water-sensitive dye patterns are aligned with the weft fiber sleeves.
[0019] By adopting the above technical solution, the warp water-sensitive dye pattern and the weft water-sensitive dye pattern will change color when exposed to water. When the second layer of silicone-acrylic topcoat leaks, the corresponding warp water-sensitive dye pattern and weft water-sensitive dye pattern areas will change color, alerting the leakage area and making it easier for maintenance personnel to carry out repairs.
[0020] Preferably, the warp water-sensitive dye pattern and the weft water-sensitive dye pattern both include a water-chromic surface layer and a water-swelling bottom layer, the water-chromic surface layer is coated on the surface of the water-swelling layer, and the water-swelling layer is arranged on the surface of the smooth putty layer.
[0021] By adopting the above technical solution, when the second silicone acrylic topcoat layer leaks, the water-discoloring surface layer will change color when exposed to water, and the water-swelling layer will swell, squeezing the second silicone acrylic topcoat layer, reducing the leakage gap and reducing the risk of further leakage.
[0022] Preferably, the middle layer further includes a primer layer, and the primer layer is arranged between the granite texture paint layer and the base layer.
[0023] In summary, the present application includes at least one of the following beneficial technical effects:
[0024] 1. The middle layer of granite texture paint has a limiting net, which can limit the aggregate, reduce the risk of large-scale movement of aggregate under gravity or external force during construction, ensure the overall quality of the coating, and reduce the construction difficulty of construction personnel.

DETAILED DESCRIPTION
[0030] The following is combined with Figure 1-4 This application is described in further detail.
[0031] like Figure 1 , Figure 2 As shown, the water-based colorful architectural coating comprises a base layer 1, a middle layer 2 and a surface layer 3.
[0032] In this embodiment, the base layer 1 can select a flexible putty layer, specifically, such as elastic putty or flexible polymer putty, which can not only fill the slight unevenness of the base layer 1, but also provide a flat and flexible base for the granite paint, thereby enhancing the adhesion and decorative effect of the coating.
[0033] like Figure 1 , Figure 2 As shown, the middle layer 2 includes a granite texture paint layer 21 and a primer layer 22, and the primer layer 22 is arranged between the granite texture paint layer 21 and the base layer 1. The primer layer 22 can be made of colorful paint, and then use a paint brush or a spray gun and other tools to evenly brush or spray the paint on the base layer 1. After drying and curing, a rich and diverse color effect will be displayed. In this embodiment, the primer layer 22 adopts a water-based closed primer, which is an environmentally friendly paint with excellent sealing and adhesion. It can close the pores of the base layer 1 to prevent moisture and alkaline substances from seeping out, thereby avoiding adverse effects on the granite paint. At the same time, the water-based closed primer can also enhance the bonding force between the base layer 1 and the granite texture paint layer 21, and improve the overall performance of the coating.
[0034] like Figure 1 , Figure 2 As shown, the granite texture paint layer 21 is arranged between the primer layer 22 and the surface layer 3, and has a limiting net. The limiting net has a plurality of grids, and aggregates are arranged in the grids. The aggregates and the grids are fixedly connected by resin.
[0035] Preferably, the limiting net includes an inner net 211 and an outer net 212. The inner net 211 is close to the base layer 1, and includes a plurality of warp fiber bundles 2111 and weft fiber bundles 2112. The warp fiber bundles 2111 and weft fiber bundles 2112 are staggered to form a grid. The outer net 212 is close to the surface layer 3, and includes a plurality of warp fiber sleeves 2121 and weft fiber sleeves 2122. The warp fiber sleeves 2121 and weft fiber sleeves 2122 are staggered to form a grid. Both the warp fiber sleeves 2121 and the weft fiber sleeves 2122 are glass fiber sleeves.
[0036] like Figure 3 , Figure 4 As shown, specifically, the warp fiber bundle 2111 and the weft fiber bundle 2112 are both glass fiber bundles, and the glass fiber bundles include a glass fiber core 2113 and a protective tube 2114. There are at least two glass fiber cores 2113. In this embodiment, each protective tube 2114 has seven glass fiber cores 2113, one of which is located in the middle, and the other six are twisted around the middle glass fiber core 2113. The protective tube 2114 can adopt a polyvinyl chloride sleeve, which has good compatibility with the resin and can improve the overall strength of the granite texture paint layer 21.
[0037] like Figure 1 , Figure 2 As shown, the surface layer 3 includes two layers of silicone acrylic topcoat 31 and a smooth putty layer 32 . The smooth putty layer 32 is arranged on the surface of the granite texture paint layer 21 , and the two layers of silicone acrylic topcoat 31 are arranged on the surface of the smooth putty layer 32 .
[0038] Preferably, the surface of the smooth putty layer 32 is provided with warp water-sensitive dye patterns 33 and weft water-sensitive dye patterns 34 . The warp water-sensitive dye patterns 33 are aligned with the warp fiber sleeves 2121 , and the weft water-sensitive dye patterns 34 are aligned with the weft fiber sleeves 2122 .
[0039] In this embodiment, the warp water-sensitive dye pattern 33 does not correspond one-to-one with the warp fiber sleeve 2121, but is aligned with one of the warp fiber sleeves 2121 after being spaced apart from several warp fiber sleeves 2121. The correspondence between the weft water-sensitive dye pattern 34 and the weft fiber sleeve 2122 is the same.
[0040] Preferably, the warp water-sensitive dye pattern 33 and the weft water-sensitive dye pattern 34 both include a water-discoloring surface layer 35 and a water-swelling bottom layer 36 , the water-discoloring surface layer 35 is coated on the surface of the water-swelling layer, and the water-swelling layer is arranged on the surface of the smooth putty layer 32 .
[0041] The water-sensitive dyes of the warp-direction water-sensitive dye patterns 33 and the weft-direction water-sensitive dye patterns 34 can be made of weak alkali, such as Na2CO3, with a pH value between 10-11.
[0042] The water-swellable bottom layer 36 may be made of expansive soil or water-absorbing resin.
[0043] The working principle of this embodiment is as follows: the base layer 1 of the coating is applied on the base layer 1, and the middle layer 2 is arranged on the base layer 1. Since the granite texture paint layer 21 of the middle layer 2 has a limiting net, the aggregate can be limited. When the second silicone acrylic topcoat layer 31 leaks, the corresponding longitudinal water-sensitive dye pattern 33 and the weft water-sensitive dye pattern 34 will change color, reminding the leakage area and facilitating maintenance personnel to carry out repairs.
[0044] The above are all preferred embodiments of the present application, and the protection scope of the present application is not limited thereto. Therefore, any equivalent changes made according to the structure, shape, and principle of the present application should be included in the protection scope of the present application.
