Description

Technical Field

[0001] The present invention relates to a surface decoration of an object, a preparation method thereof, and a method for decorating the surface of an object, and in particular to a method for producing an impregnation-coated sandwich wall cloth with a phase change energy storage function on the surface of an object such as a building, and an impregnation-coated sandwich wall cloth with a phase change energy storage function. Background Art

[0002] Early wall decoration used wall paint, which is used to decorate and protect building walls, making them beautiful and neat. It also protects the walls and extends their service life. In the specific technical field, the development of various binder film-forming technologies has greatly improved the performance of coatings, especially the development of emulsion formulation technology. Existing coatings form a composition system composed of binders, fillers, pigments, additives and solvents (such as water). In order to reflect the environmental performance of coatings, inorganic binders (such as silicates) and various water-based emulsions are often used as the bonding and film-forming substances of coatings. However, traditional coatings have many defects in color, texture, feel, etc.

[0003] Wall covering, also known as wall cloth, is a type of interior decoration material (fabric) used for wall coverings. Prints or reliefs are created on the base fabric and are widely used in the interior decoration of homes, offices, guesthouses, and hotels. Wall covering offers a variety of colors, rich patterns, luxurious style, easy installation, and affordable prices, making it widely used in building decoration.

[0004] However, wall coverings also have the following problems: 1) Poor environmental performance. Wall coverings need to be glued to the wall surface. Most of the adhesives currently used are still organic solvent-based adhesives, which contain a large amount of toluene, formaldehyde and other organic substances that are harmful to the human body; 2) Not tear-resistant. Wall coverings are adhered to the wall with adhesives. The adhesion between the adhesive and the wall is uncontrollable, and the bonding strength is often poor, especially environmentally friendly adhesives such as glutinous rice glue, which easily absorb water and mold, causing the wall covering to fall off; 3) The joints are too obvious. Since wall coverings have a certain thickness and are prefabricated products directly glued to the wall, especially when they have patterns, the joints between the wall coverings are very obvious, which seriously affects the decorative effect and the design of the wall covering patterns and patterns; 4) Poor 3D effect. Most wall coverings are flat prints and do not have 3D effect. Even if they are made into 3D effect through optical principles, they are often thick and have great limitations on viewing angles.

[0005] Therefore, how to make wall coverings that are both decorative and tear-resistant is of great significance to the field of building decoration. Summary of the Invention

[0137] The method of making phase change energy storage impregnation coating sandwich wall cloth on the surface of an object according to the present invention has the following characteristics:

[0138] Beneficial effects:

[0139] 1) The phase change energy storage impregnation coating sandwich wall cloth of the present invention is coated on the surface of an object, and the coating has sufficient adhesion to the surface of the object, and the entire coating surface is firm and reliable; there is no obvious connection seam at the fiber network sandwich joint, and the joint is not easy to crack.

[0140] 2) The paint infiltrates, penetrates and fills the meshes of the network structure of the fiber texture network core, so that the fibers of the fiber texture network core and the impregnated coating paint have a bite and bonding effect, especially when the meshes of the three-dimensional interpenetrating network structure are three-dimensionally distributed, multiple meshes are interconnected, and the infiltration, penetration and filling of the paint in the meshes are also three-dimensional. Therefore, the present invention can provide a tighter combination between the paint and the fiber texture network core. Therefore, compared with the wallpaper texture, it has significantly higher peeling resistance.

[0141] 3) The present invention forms a sandwich structure, in which the fiber texture network sandwich is located between the impregnated coatings. After the second coating is applied to the surface of the fiber texture network sandwich, the thickness of the fiber surface increases, while the second coating on the mesh surface is inwardly sunken during the curing process, thereby presenting the texture of the fiber texture network sandwich. Therefore, the present invention has the advantage of controllable texture, and the fiber texture network sandwich can be standardized and mass-produced to ensure the consistency of the texture; at the same time, the texture shape can be diversified, making the coating texture shape rich and varied.

[0142] 4) The present invention forms a sandwich structure, which has significantly better peeling resistance than the texture coating made by layering wallpaper and wall cloth. Compared with the coating made of glass fiber cloth in the prior art, the coating weight is significantly smaller and the crack resistance is not compromised.

[0143] 5) The method of the present invention can produce a rich texture similar to wallpaper on the surface of an object, without obvious gaps at the joints, and the texture is well-coherent; the method of the present invention can use paint to produce a rich texture, feel and pattern of wall cloth on the surface of an object; the base coat and the fiber network sandwich pattern are combined with each other, and the color expression of the decorative surface is richer.

[0144] 6) The wall cloth of the present invention has large air permeability and good air permeability.

[0145] 7) The present invention can adjust the temperature and increase the comfort of the environment. BRIEF DESCRIPTION OF THE DRAWINGS

[0153] Example 1

[0154] Reference Figure 1A The structure of the phase change energy storage impregnation coating sandwich wall cloth of the present invention is as follows: it includes a base color coating 11, an impregnation coating composite sandwich coating complex on the surface of the base color coating, and the impregnation coating composite sandwich coating complex includes a transparent or translucent first coating 20, a transparent or translucent second coating 40, and a fiber network sandwich 30 sandwiched between the first coating 20 and the second coating 40. Among them, the second coating 40 is loaded with a phase change energy storage material (for example, the phase change material is encapsulated into microcapsules and then added to the inorganic dry powder coating), and the fibers of the fiber texture network sandwich 30 can be loaded with phase change energy storage material or themselves made of phase change energy storage material. Generally, the phase change energy storage temperature range of the coating and the fiber is different. In this case, the temperature range of the phase change energy storage can be increased.

[0155] In this embodiment, the fiber texture network core 30 contains a three-dimensional interpenetrating network structure formed by fibers, and the fibers include horizontal fibers, vertical fibers, and oblique fibers. Figure 2A-2C Several top-view structures of fiber texture network sandwich 30 are given, referring to Figure 2A-2C In the same plane, the transverse fibers 5 intersect with the longitudinal fibers 4 and the oblique fibers 3, and the intersecting fibers form a mesh 2. The intersections between the fibers are at least partially connected together to form connection points 1. For example, the connection points can be one or more of the connection methods such as welding and chemical bonding. In this embodiment, welding is preferred.

[0156] The percentage of the number of fiber connection points to the number of fiber intersections can be 1%-100%, that is, all intersections can form connection points, or only some intersections can form connection points. Figure 2A The intersection between the transverse fibers indicated by mark 5 and the longitudinal fibers indicated by mark 4 does not form a connection point, but the intersection between the transverse fibers indicated by mark 5 and the oblique fibers indicated by mark 3, and the intersection between the longitudinal fibers indicated by mark 4 and the oblique fibers indicated by mark 3 both form a connection point 1.

[0157] It should be understood that the fiber-textured network core 30 of the present invention is a three-dimensional structure, meaning that the fibers are not all arranged in the same plane. In reality, there are fibers oriented horizontally, vertically, and obliquely, and these fibers intersect and form at least some connection points. Furthermore, due to the length of the fibers, each fiber may have multiple horizontal, vertical, and oblique portions, and these multiple horizontal, vertical, or oblique portions may or may not exist in the same horizontal, vertical, or oblique plane.

[0158] like Figure 3 As shown, transverse meshes 22 are formed between the transverse fibers 31 in the upper horizontal plane and the transverse fibers 32 in the lower horizontal plane, and longitudinal meshes 21 are formed between the transverse fibers 31 and the vertical fibers 33 in the vertical plane. The transverse meshes 22 are connected to the longitudinal meshes 21. Similarly, oblique meshes 23 are formed between the transverse fibers 31 and the oblique fibers, and between the vertical fibers 33 and the oblique fibers. Figure 3 The case where two oblique meshes 23 are connected is shown, but the oblique meshes 23 may also be connected with the transverse meshes 22 and / or the longitudinal meshes 21 .

[0159] Furthermore, the transverse fibers 31 in the upper horizontal plane and the transverse fibers 32 in the lower horizontal plane may be two horizontal parts of the same fiber or two fibers.

[0160] 6 , the method for producing the phase change energy storage impregnation coating sandwich wall cloth in this embodiment is as follows:

[0161] Reference Figure 6A , a base color coating 11 is applied on the surface of the wall 10,

[0162] After the base color coating 11 is dried, a transparent or translucent first inorganic dry powder coating is applied to form a transparent or translucent first coating 20. The first coating only needs to cover the surface of the base color coating 11, but does not need to be smoothed.

[0163] Reference Figure 6B Before the first inorganic dry powder coating loses its plasticity, the fiber texture network sandwich 30 is applied to the first inorganic dry powder coating. The first inorganic dry powder coating infiltrates the fibers, or the first inorganic dry powder coating infiltrates the fibers by applying pressure, and penetrates into the pores of the three-dimensional interpenetrating network structure. During this process, the fiber texture network sandwich 30 may be pressed into contact with the surface of the base coating 11, or may not be in contact. The first inorganic dry powder coating may also penetrate the mesh of the fiber texture network sandwich 30 and seep out from the mesh, but this is not necessary.

[0164] Reference Figure 6C, applying a transparent or translucent second inorganic dry powder coating, i.e., a transparent or translucent second coating 40, and applying pressure so that the second inorganic dry powder coating infiltrates the three-dimensional interpenetrating network structure fibers and penetrates into the meshes of the three-dimensional interpenetrating network structure; forming a sandwich coating;

[0165] After the pressure is applied, the first inorganic dry powder coating and the second inorganic dry powder coating come into contact in the mesh and are tightly combined under the pressure. Figure 6C As shown;

[0166] The sandwich coating is cured. During the curing process of the second inorganic dry powder coating, the coating located on the pore surface of the three-dimensional interpenetrating network structure collapses inward, while the coating located on the fiber surface is blocked by the fibers and does not collapse or collapses slightly, thereby forming a texture; Figure 1A And during the curing process of the first inorganic dry powder coating and the second inorganic dry powder coating, the closely combined parts are connected into one.

[0167] Reference Figure 1B , the surface fibers of the fiber texture network sandwich 30 may be uneven, such as Figure 1B The first part of the fibers 301 is lower than the second part of the fibers 302, but the surface of the fiber texture network sandwich 30 can also be made flat through a flattening process; during the curing process of the second coating 40, the coating on the fiber surface is blocked by the fibers and stays on the fiber surface. For example, a lower texture 501 is formed on the surface of the first part of the fibers 301, and a higher texture 502 is formed on the surface of the second part of the fibers 302. The second coating 40 sinks at the mesh 2 to form a concave texture part 503. Therefore, an uneven texture 50 is formed, and the shape of the texture 50 is the same as or very close to the convex and concave structure of the fiber texture network sandwich 30 surface.

[0168] Reference Figures 5A-5B The figure shows the coating infiltrating the fibers and seeping into the mesh. The dark portion represents the coating or coating filling the mesh, while the light portion represents the fibers. Because the coating infiltrates and fills the mesh of the three-dimensional interpenetrating network structure of the fiber-textured network core 30, the fibers of the fiber-textured network core and the impregnated coating achieve a bite and bond. Furthermore, because the pores of the three-dimensional interpenetrating network structure are three-dimensionally distributed and interconnected, the coating infiltrates, penetrates, and fills the pores in a three-dimensional manner. Therefore, the present invention provides a tighter bond between the coating and the fiber-textured network core 30, resulting in excellent peel resistance.

[0169] Reference Figure 2BTaking polyethylene fiber as an example, during the hot pressing and welding process between the three-dimensionally arranged fibers of the fiber texture network sandwich 30 of the present invention, some fibers will melt to form a block structure 100. In this way, when the first inorganic dry powder coating and the second inorganic dry powder coating infiltrate and penetrate and fill the mesh, the bite force on the fibers can be further increased.

[0170] Reference Figure 2C If the hot pressing or bonding is excessive, the mesh 2 surrounded by the fibers will be filled with melted and cast fibers or adhesives, but new meshes 200 will be formed in the cast fibers or adhesives, and the new meshes 200 will also be connected to the mesh 2 surrounded by the fibers. The filling of the coating in the mesh of the fiber texture network sandwich 30 will be more complicated, which can further increase the tear resistance (peeling resistance).

[0171] Reference Figure 4A-4B The fiber diameter of the fiber texture network sandwich of the present invention is preferably 1 μm-5000 μm, more preferably 1 μm-1000 μm, more preferably 1 μm-100 μm, more preferably 1 μm-50 μm, more preferably 5 μm-50 μm, more preferably 5 μm-40 μm. The pore size of the fiber texture network sandwich is preferably 0.1 mm-5 mm, more preferably 0.1 mm-3 mm, more preferably 0.1 mm-1 mm. The density of the fiber texture network sandwich 30 is preferably 10-300 g / m 2 , more preferably 15-200g / m 2 , more preferably 20-150g / m 2 , more preferably 20-100g / m 2 , more preferably 20-50g / m 2 .

[0172] The thickness of the fiber texture network core 30 is preferably 0.1 mm to 10 mm, more preferably 0.1 mm to 5 mm, more preferably 0.1 mm to 1 mm, more preferably 0.1 mm to 0.5 mm, and more preferably 0.2 mm to 0.4 mm, such as 0.25 mm, 0.28 mm, 0.3 mm, 0.33 mm, 0.35 mm, 0.37 mm, etc. The thickness of the fiber texture network core 30 of the present invention is preferably greater than or equal to the sum of the thicknesses of the first and second coating layers, and more preferably greater than the sum of the thicknesses of the first and second coating layers. The thickness of the second coating layer is preferably less than or equal to 1 / 2 of the thickness of the fiber texture network core 30.

[0173] Reference Figure 7The coating fiber composite wall cloth formed in this embodiment has a layered sense of 3D pattern, namely: the base coating 11 is the base, the pattern in the fiber texture network sandwich 30 forms a relief pattern, and the transparent or translucent second coating 40 is covered to form a surface layer, covering the relief pattern. The light passes through the transparent or translucent first coating 20 and the second coating 40, and the color of the base coating 11 becomes softer. It forms a seamless three-dimensional pattern decorative effect together with the fiber color and pattern color of the fiber network sandwich. For example, the base coating is blue, and a colorful flower pattern is provided on the white fiber texture network sandwich 30. In this way, a flower pattern with a 3D effect on a blue base is formed, such as Figure 7 As shown, the floral pattern is very obvious and clear, and the pattern seems to float in the wall covering.

[0174] At the same time, when the second coating 40 sinks into the mesh during the drying process, a texture corresponding to the fiber network core is formed on the surface of the second coating 40, such as Figure 7 As shown, the fiber network core 30 protrudes from the surface of the second coating 40, forming an uneven and fine texture (texture) on the surface of the second coating 40, and the fibers form obvious fluff on the surface of the second coating, which constitutes the velvet effect of flocking wall cloth, increases the feel, and overcomes the cold decorative effect of the paint.

[0175] Both the first and second inorganic dry powder coatings of the present invention preferably utilize alkali metal silicates as film-forming materials and may contain fillers, pigments, additives, and other components. The particle size of the largest particles (typically fillers) of all components is preferably ≤50 μm, more preferably ≤30 μm, more preferably ≤20 μm, and even more preferably ≤10 μm. The particle size is preferably ≤1 / 5, more preferably ≤1 / 10, and even more preferably ≤1 / 100 of the average pore size of the fiber-textured network core; more preferably, ≥1 / 1000.

[0176] Example 2

[0177] The method for making the phase change energy storage impregnation coating sandwich wall cloth in this embodiment is as follows:

[0178] A closed primer is applied on the surface of the wall 10, and then a base color coating 11 with a phase change energy storage function is applied on the closed primer.

[0179] After the base coating 11 is dried, a transparent organic adhesive, such as an epoxy resin adhesive, is applied to a portion of the surface of the base coating 11, and the fiber texture network sandwich 30 is adhered to the surface of the base coating 11 through the organic adhesive;

[0180] Applying an organic coating to form a second coating layer, applying pressure to allow the organic coating to penetrate the three-dimensional interpenetrating network structure fibers and penetrate into the meshes of the three-dimensional interpenetrating network structure to form a sandwich coating layer;

[0181] When the sandwich coating is cured, the organic coating on the mesh surface collapses inwards, while the organic coating on the fiber surface is blocked by the fibers and does not collapse or collapses slightly, thereby forming a texture.

[0182] The fiber diameter of the fiber texture network sandwich is 20 μm. The mesh size of the fiber texture network sandwich is 0.5 mm. The density of the fiber texture network sandwich 30 is preferably 50 g / m 2 .

[0183] The thickness of the fiber texture network core 30 is preferably 0.25 mm, the thickness of the first coating layer is 0.1 mm, and the thickness of the second coating layer is 0.13 mm.

[0184] Generally, there may be no solid particles in the organic adhesive or organic coating, but solid particles may be present. When solid particles are present, the particle size of the largest particle (generally a filler) is 20 μm.

[0185] The patterns formed by the fiber texture network sandwich visually create a suspended effect. In this embodiment, the second coating can also be a thicker coating than the second coating in Example 1. For example, the thickness of the second coating is greater than the thickness of the fiber network sandwich, which can increase the thickness and depth of the 3D layering effect.

[0186] Example 3

[0187] The method for making the phase change energy storage impregnation coating sandwich wall cloth in this embodiment is as follows:

[0188] The surface of the wall 10 is coated with a base color coating 11 having a phase change energy storage function.

[0189] After the base color coating 11 is dried, a transparent or translucent first organic coating, such as latex paint, is applied on the surface of the base color coating 11 to form a transparent or translucent first coating 20;

[0190] Applying the fiber texture network core 30 to the surface of the first coating 20, and applying pressure to the fiber texture network core 30 so that the first organic coating penetrates the fibers and penetrates into the pores of the three-dimensional interpenetrating network structure;

[0191] Applying a transparent or translucent second organic coating, which may also be a latex paint, as the transparent or translucent second coating layer, and applying pressure so that the second organic coating layer penetrates into the fibers of the three-dimensional interpenetrating network structure and into the meshes of the three-dimensional interpenetrating network structure to form a sandwich coating layer;

[0192] When the sandwich coating is cured, the organic coating on the mesh surface collapses inwards, while the organic coating on the fiber surface is blocked by the fibers and does not collapse or collapses slightly, thereby forming a texture.

[0193] The fiber diameter of the fiber texture network sandwich is 30 μm. The mesh size of the fiber texture network sandwich is 1 mm. The density of the fiber texture network sandwich 30 is preferably 100 g / m 2 .

[0194] The thickness of the fiber texture network core 30 is preferably 0.3 mm. The thickness of the first coating layer is 0.15 mm, and the thickness of the second coating layer is 0.15 mm.

[0195] The organic coating may be an acrylic emulsion as a film-forming material. Solid particles may or may not exist in the organic coating. When solid particles exist, the maximum particle size (generally filler) is 40 μm.

[0196] Example 4

[0197] The method for making phase change energy storage impregnation coating sandwich wall cloth in this embodiment is as follows

[0198] A base color coating 11 is applied on the surface of the wall 10.

[0199] After the base color coating 11 is dried, a transparent or translucent first inorganic dry powder coating is spot-coated on the surface of the base color coating to form a first coating 20;

[0200] A fiber texture network sandwich 30 made of a phase change energy storage material is applied to the surface of the first coating 20, and pressure is applied to the fiber texture network sandwich 30 so that the first inorganic dry powder coating penetrates the fibers and penetrates into the pores of the three-dimensional interpenetrating network structure. In this embodiment, the fiber network sandwich is a two-dimensional structure. For example, the fibers are arranged in the same plane, and can be arranged in an orderly manner (such as a warp and weft arrangement) or in a disordered arrangement. The mesh holes are basically arranged in a direction that penetrates the fiber network sandwich.

[0201] Applying a transparent or translucent second inorganic dry powder coating, and applying pressure to allow the second inorganic dry powder coating to penetrate the fibers of the fiber texture network structure and penetrate into the meshes of the network structure to form a sandwich coating;

[0202] When the sandwich coating is cured, the coating on the mesh surface collapses inwards to a greater extent, while the coating on the fiber surface is blocked by the fibers and does not collapse or collapses slightly, thereby forming a texture.

[0203] In this embodiment, wall coverings with velvet effects and 3D pattern effects can also be formed.

[0204] Wherein, the first inorganic dry powder coating and the second inorganic dry powder coating can both be phase change energy storage coatings.

[0205] Example 5

[0206] The method for making phase change energy storage impregnation coating sandwich wall cloth in this embodiment is as follows

[0207] Applying a base color coating 11 on the surface of the wall 10;

[0208] After the base coating 11 is dried, the top of the fiber texture network sandwich 30 is adhered to the surface of the base coating 11 by a self-adhesive sticker. In this embodiment, the fiber texture network sandwich 30 has a pattern composed of dense meshes.

[0209] A transparent or translucent second inorganic dry powder coating (or an organic coating, such as latex paint) is applied to the area avoiding the self-adhesive sticker, and pressure is applied to allow the second inorganic dry powder coating to penetrate the fibers of the three-dimensional interpenetrating network structure and into the meshes of the three-dimensional interpenetrating network structure; the self-adhesive sticker is removed, and the second inorganic dry powder coating is applied to the remaining area to form a sandwich coating;

[0210] When the sandwich coating is cured, the coating on the mesh surface collapses inwards to a greater extent, while the coating on the fiber surface is blocked by the fibers and does not collapse or collapses slightly, thereby forming a texture.

[0211] The dense mesh pattern forms a relief pattern on the surface of the first coating layer, and a corresponding texture can also be formed on the surface of the second coating layer. In addition, the wall covering produced also has a velvet effect.

[0212] Among them, the second inorganic dry powder coating is a phase change energy storage coating.

[0213] Example 6

[0214] The method for making phase change energy storage impregnation coating sandwich wall cloth in this embodiment is as follows

[0215] A closed primer is applied on the surface of the wall 10, and a base color coating 11 with a phase change energy storage function is applied on the surface of the closed primer.

[0216] After the base coating 11 is dried, the top of the fiber texture network sandwich 30 is adhered to the surface of the base coating 11 by a self-adhesive sticker. In this embodiment, the fiber texture network sandwich 30 has a pattern composed of dense meshes.

[0217] Applying a transparent or translucent second inorganic dry powder coating, applying pressure so that the second inorganic dry powder coating penetrates into the three-dimensional interpenetrating network structure fibers and into the meshes of the three-dimensional interpenetrating network structure to form a sandwich coating;

[0218] When the sandwich coating is cured, the coating on the mesh surface collapses inwards to a greater extent, while the coating on the fiber surface is blocked by the fibers and does not collapse or collapses slightly, thereby forming a texture.

[0219] The second inorganic dry powder coating can also be a phase change energy storage coating, and preferably has at least a partial difference in the phase change energy storage temperature range from the base color coating, thereby increasing the temperature range for energy storage.

[0240]

[0241] In general, the method of the present invention can produce wallpaper with rich texture, and at the same time can make the texture and coating have good tearing and peeling resistance; in particular, there is no visible seam at the fiber network core of the present invention, and the obtained texture has good continuity, such as Figure 7 shown.
