[0027] The embodiments of the present disclosure will be described in detail below with reference to the drawings.

[0028] The embodiments of the present disclosure will be described in detail below with reference to the drawings.

[0029] It should be noted that various aspects in the following description are presented in terms of examples. It should be appreciated that these aspects are presented for purposes of illustration and description and are not intended to limit the scope of the disclosure. Moreover, the aspects can be implemented in any number of ways, including as computer-readable storage media storing computer-executable instructions that, when executed by a computer, perform the methods described herein.

[0030] It should also be noted that the figures provided in the following embodiments are only schematic and that the dimensions of the various components are not necessarily to scale with one another. Furthermore, the figures are provided in a manner that is intended to simplify the disclosure, and the shapes and proportions of the various components can be varied in actual implementations.

[0031] Furthermore, in the following description, numerous specific details are provided for a thorough understanding of the examples. One skilled in the relevant art will recognize, however, that the aspects described herein can be practiced without one or more of the specific details, or with other methods, components, materials, and so forth.

[0032] As Figure 1 and Figure 2As shown, the instant application of a convenient peelable gouache painting comprises five main components: a base plate 1, an elastic adhesive layer 2, a reinforcing fiber mesh 3, a gouache layer 4 and a transparent protective film 5. Each component is assembled in a specific manner to ensure that it has excellent peelability and reusability.

[0033] Specifically, the base plate 1 is at the bottom layer of the overall structure, responsible for providing support and stability functions for the entire device. In order to ensure the best stable support, the base plate 1 material needs to have sufficient mechanical strength and flat surface to evenly bear the rest. The upper surface of the base plate 1 is attached with an elastic adhesive layer 2, which has flexibility and exhibits relatively weak adhesion characteristics, which allows the gouache painting on it to be easily separated from the bottom surface during the peeling process without causing damage or leaving marks on the picture. In terms of material selection, silicone-modified pressure-sensitive adhesive can be used to achieve the design intention of this elastic adhesive layer 2, which can provide moderate adhesion while ensuring easy peeling.

[0034] The reinforcing fiber mesh 3 is embedded in the elastic adhesive layer 2 mentioned above. This mesh component is arranged in a crisscross pattern throughout the elastic adhesive layer 2, aiming to improve the internal structural stability and mechanical resistance of the latter, effectively preventing the adhesive layer and the gouache layer 4 closely connected thereto from being torn or damaged when subjected to pulling or other external forces. Suitable reinforcing fiber mesh 3 can be woven by materials such as polyester fiber or carbon fiber.

[0035] Continuing in the upward direction, there is the gouache layer 4 formed by the coating material. It is one of the main components of this product and directly carries the expression content of the artwork. The choice of gouache material is crucial, usually prepared by mixing traditional clay pigments with appropriate adhesive substances, easy to apply to the bottom layer and maintain shape for a long time while maintaining good color expression and texture. In order to meet the subsequent peeling operation requirements, it is necessary to specially control the concentration of the slurry to achieve a suitable consistency but not too sticky state.

[0036] The top layer is the transparent protective film 5, which covers the surface of the gouache layer 4, aiming to resist external pollution and physically isolate the internal gouache components, ensuring that the picture remains intact and maintains clarity and beauty. The transparent protective film 5 is preferably made of high molecular polymer, and is fixed between the contact surface of the underlying gouache with low viscosity medium as a connecting medium, ensuring that it can be easily peeled off and remain unchanged in multiple uses.

[0037] The multi-layer composite structure solves the problems of traditional clay paintings by reasonably configuring the material properties of each layer. The moderate adhesion provided by the elastic adhesive layer 2, combined with the characteristics of easy detachment, the internal reinforcement rib network structure to prevent accidental breakage, and the external film protection to isolate environmental influences, together overcome the above technical defects.

[0038] Reference Figure 3 In one embodiment, the bottom plate 1 of the convenient-to-unstick clay painting of the present application is made of a porous structure material. This porous material can significantly reduce the overall weight and improve air permeability, ensuring that the bottom plate 1 does not deform easily during long-term use, while also having good environmental performance. The bottom plate 1 has suction cups 6 arranged at the four corners on the back, which enhances the stability between the bottom plate 1 and the placement surface. Whether the clay painting is placed on a smooth table top or wall, the suction cups 6 effectively prevent the bottom plate 1 from shifting during the unstick operation, improving the convenience and stability of use.

[0039] Specifically, the bottom plate 1 provides a stable support base for the entire device. The bottom plate 1 made of a porous structure material not only reduces the overall weight of the entire clay painting, but also improves air circulation, prolonging its service life. To increase the reliability of the fixation, suction cups 6 are arranged at the four corners on the back of the bottom plate 1, which can be adsorbed on the contact surface by negative pressure, ensuring that the bottom plate 1 remains fixed and does not slide even under external forces, such as when unstick or moving. For example, a porous structure material with good elasticity can be used to manufacture the bottom plate 1, and high-adhesion suction cups 6 can be installed at specific positions on the bottom. This design not only ensures the stability of the clay painting during display and transportation, but also improves the simplicity and accuracy of the unstick operation.

[0040] Reference back Figure 2 In one embodiment, the elastic adhesive layer 2 of the convenient-to-unstick clay painting of the present application is formed by mixing a number of elastic particles 7 and low-adhesion gum material. This structure ensures the unstickability of the clay painting and the smoothness during the unstick process. Specifically, the elastic particles 7 are distributed inside the elastic adhesive layer 2, which not only improves the overall elasticity of the adhesive layer, but also reduces the generation of cohesive force during the unstick process, allowing the clay painting to be easily peeled away from the base without leaving residual clay.

[0041] The elastic particles 7 can be micron-sized silica or polyurethane microspheres, which have excellent elasticity and pressure resistance, and can further improve the flexibility of the elastic glue layer 2. After adding these elastic particles 7 in the elastic glue layer 2, the entire mud painting structure is more stable and the peeling operation is more smooth. Specifically, micron-sized silica and polyurethane microspheres are uniformly distributed in the elastic glue layer 2, combined with low-viscosity colloidal material, forming a composite layer with unique properties. Through this design, the elastic particles 7 not only improve the tensile properties of the glue layer, but also ensure that the surface pattern and structure are not damaged during peeling, thereby providing better user experience and higher reusability for the mud painting.

[0042] For example, the low-viscosity colloidal material and the elastic particles 7 can be coated together on the upper surface of the base plate 1 through a specific coating process. Then, after curing treatment, it is ensured that the two are tightly combined to form a uniformly distributed and excellent performance elastic glue layer 2. Next, the reinforcing fiber mesh 3 and the mud layer 4 are sequentially laid on it, and the transparent protective film 5 is used to cover the topmost layer. Through such a sequence of procedures and strict process control, seamless connection and performance maximization of each layer are ensured.

[0043] In one embodiment, a nano-sized silicone oil 8 is also added to the elastic glue layer 2 of the mud painting with convenient peeling of the present application. This silicone oil 8 can significantly reduce friction during peeling, further improve surface smoothness, and reduce adhesion during peeling to avoid residue of the mud. The elastic glue layer 2 originally has flexibility and weak adhesion characteristics. By adding nano-sized silicone oil 8, not only the original advantages are enhanced, but also the peeling process is more smooth and stable. The nano-sized silicone oil 8 is uniformly dispersed in the elastic glue layer 2, so that it has uniform and consistent friction-reducing effect throughout the thickness. The additive amount is accurately controlled during the manufacturing process, and is finally verified by multiple rounds of testing to achieve the desired performance.

[0044] Specifically, the nano-sized silicone oil 8 can be mixed into the raw materials of the elastic glue layer 2 during the manufacturing process to ensure that the two are fully mixed and uniformly distributed during the molding process. In this way, when the finished product needs to be peeled, whether it is a large area or a small area operation, the silicone oil 8 will play an effective friction-reducing effect, so that the surface layer of the mud painting is more easily peeled without residue of the mud. For example, the two materials are mixed by a specific stirring device and then coated on the base plate 1 to form the elastic glue layer 2. The key of this step is to maintain the stable dispersion state of the nano-sized silicone oil 8 and control the appropriate amount of additive to achieve the expected effect.

[0045] In one embodiment, the reinforcing fiber mesh 3 of the easy-to-peel mud painting of the present application is a three-dimensional grid structure. The three-dimensional grid structure is composed of crisscrossing fibers uniformly distributed inside the elastic glue layer 2. This fiber structure not only enhances the overall mechanical properties of the elastic glue layer 2, but also significantly improves its tear resistance and deformation resistance. The presence of the reinforcing fiber mesh 3 makes the entire mud painting structure more robust, ensuring that it will not break or undergo plastic deformation during the peeling process. Specifically, the crisscrossing arrangement of the reinforcing fiber mesh 3 provides support to the elastic glue layer 2 in multiple directions, ensuring material consistency and integrity.

[0046] In addition, the reinforcing fiber mesh 3 is closely connected to the elastic glue layer 2, ensuring seamless integration between the fiber mesh and the elastic glue layer 2. In terms of specific installation methods, the reinforcing fiber mesh 3 is completely embedded in the uncured elastic glue layer 2 during production and forms a stable composite structure along with the curing of the elastic glue layer 2. This not only avoids the possibility of the fiber mesh falling off, but also allows the fiber mesh to uniformly distribute and provide all-around reinforcement within the elastic glue layer 2.

[0047] For example, during actual manufacturing, the elastic glue can be applied to the upper surface of the base plate 1, and then the pre-prepared three-dimensional grid structure reinforcing fiber mesh 3 can be carefully laid on top. A layer of elastic glue can then be uniformly applied to cover the reinforcing fiber mesh 3 until it is completely embedded and wrapped. After the elastic glue layer 2 is cured, the mud layer 4 can be directly applied to its upper surface, and finally a transparent protective film 5 can be used to seal it, completing the overall structure. In this way, the reinforcing fiber mesh 3 is effectively embedded within the elastic glue layer 2 and functions.

[0048] In one embodiment, the reinforcing fiber mesh 3 of the easy-to-peel mud painting of the present application has a fiber diameter of 10 to 50 microns and a fiber spacing of 1 to 5 millimeters, forming a uniform mesh structure. This design ensures that the reinforcing fiber mesh 3 embedded in the elastic glue layer 2 not only does not break locally under stress, but also effectively prevents mud residue from accumulating on the base plate 1 or the peeling tool. The mesh structure is composed of materials with appropriate strength and flexibility to meet the needs of different application scenarios. The reinforcing fiber mesh 3 forms a stable and robust framework through mechanical interweaving, thereby enhancing the overall structural strength of the elastic glue layer 2. In addition, the fiber configuration under these specific parameters helps to achieve smoothness and consistency of the elastic glue layer 2 during the peeling process, reducing the risk of damage caused by external stress.

[0049] In one specific embodiment, for example, in actual production process, the reinforcing fiber mesh 3 is first prepared and then uniformly embedded in the uncured elastic glue layer 2 to ensure its correct position and uniform distribution inside the elastic glue layer 2. In order to achieve the best performance, the reinforcing fiber mesh 3 should be completely surrounded by the elastic glue layer 2 to ensure the close combination between the two. This not only improves the physical properties of the entire composite material, but also makes the final gesso painting product have good durability and reliability.

[0050] In one embodiment, the fiber material of the reinforcing fiber mesh 3 of the easy-to-peel gesso painting of the present application is selected from aramid or carbon fiber. These fiber materials have the characteristics of high strength and high modulus, which can significantly improve the overall structural strength and durability of the elastic glue layer 2, and also increase the elastic modulus of the elastic glue layer 2. Through this material selection, the gesso painting is not easy to break during peeling, and the possibility of mud residue on the substrate is reduced.

[0051] The addition of the reinforcing fiber mesh 3 enhances the mechanical properties of the elastic glue layer 2. The reinforcing fiber mesh 3 is completely embedded inside the elastic glue layer 2 to form a uniform distribution state to ensure uniform stress everywhere. Specifically, the fibers are uniformly distributed in the glue layer and tightly combined together, improving the overall structural stability and stretch resistance of the glue layer, preventing local failure of the elastic glue layer 2 during tearing. This feature also enhances the adaptability of the gesso painting in complex environments, such as large temperature changes or uneven stress.

[0052] For example, in the production of the gesso painting, the reinforcing fiber mesh 3 can be first cut into a suitable size sheet. Then it is spread and completely buried inside the elastic glue layer 2 coated on the base plate 1. Then, after a certain pressing process, the fiber material is fully combined with the glue, and then the subsequent curing treatment is carried out. Specifically, high temperature and pressure or ultraviolet curing process can be used to ensure the close combination of the fiber mesh and the elastic glue layer 2. Then the gesso layer 4 coating and transparent protective film 5 covering operations are continued to complete the final product.

[0053] In one embodiment, as shown in Figure 4 The transparent protective film 5 of the easy-to-peel gesso painting of the present application has a two-layer structure. Specifically, the inner layer is made of high-transparency PET material to ensure that the visual clarity of the painting is not affected. This PET material has excellent light transmittance and mechanical properties, and can remain stable during long-term storage and multiple peeling processes without being easily damaged or aged. The outer layer is coated with a low-adhesion coating, which not only effectively reduces the adhesion strength between the gesso layer 4, making it easy and convenient to remove the protective film, but also avoids the tearing of the gesso painting or the residue of the mud caused by strong adhesion.

[0054] In addition, the inner layer of the transparent protective film 5 is specially provided with anti-skid lines 9. The design of these lines aims to increase the friction when the protective film is peeled off, reduce the sliding phenomenon in the peeling operation, and improve the controllability and accuracy of the peeling process. The presence of the anti-skid lines 9 can ensure that the protective film can be stably peeled off without curling or misalignment even at a small angle or slow operation speed. At the same time, the anti-skid lines 9 can also effectively prevent the mud layer 4 from being unnecessarily pulled, ensuring that the picture is completely separated from the bottom plate 1 without damage.

[0055] For example, in practical applications, fine and regularly arranged anti-skid lines 9 can be manufactured on the inner surface of the PET film by precise printing technology or mold pressing process, and a layer of pre-prepared low-adhesion material is uniformly applied on the outer surface of the PET film using coating equipment. Finally, a double-layer structure transparent protective film 5 with excellent properties is formed, which is evenly laid on the formed mud layer 4 to ensure complete coverage and firm adhesion, achieving the best protection and reusability effect.

[0056] In one embodiment, the mud layer 4 of the mud painting with convenient peeling of the present application contains fine ceramic powder 10 (see Figure 2 ). These ceramic powders 10 have high hardness and low hygroscopicity. Specifically, by adding ceramic powders 10 with the above characteristics to the mud layer 4, a microporous structure can be formed therein, effectively reducing the contact area between the mud and the substrate. Due to the introduction of ceramic powder 10, the adhesion force is reduced, making the peeling process more convenient and less likely to leave residues. By controlling the addition ratio and particle size of the ceramic powder 10, the internal structure and mechanical properties of the mud layer 4 are further improved.

[0057] The ceramic powder 10 not only improves the physical properties of the mud layer 4, but also provides an innovative technical support for the overall painting. For example, by finely adjusting the distribution density and arrangement of the ceramic powder 10 in the mud layer 4, the microporous network effect inside the mud layer 4 can be enhanced, achieving a more efficient isolation function. This optimization ensures that the work can maintain good integrity and stability during multiple peeling processes.

[0058] Specifically, in one embodiment, the ceramic powder 10 of the appropriate specification can be pre-mixed during the configuration of the mud slurry. When the mud is applied to the surface of the elastic adhesive layer 2, it is ensured that the ceramic powder 10 can be uniformly dispersed in the entire mud layer 4, forming an ideal microporous structure, so that the finished product meets the expected technical standard requirements. Great attention should be paid to the uniformity of the slurry mixing and the stirring degree during this process.

[0059] In one embodiment, the thickness of the clay layer 4 of the easy-to-unstick clay painting of the present application is less than the thickness of the transparent protective film 5. This thickness difference ensures that during the unstick process, the clay layer 4 is not easily left with residual clay in some areas due to uneven thickness, thereby improving the consistency and operability of the entire painting. The design of the thickness of the clay layer 4 fully considers the actual needs of the painting as the main body and the physical properties during the unstick process.

[0060] The clay layer 4 is coated on the elastic adhesive layer 2, and the transparent protective film 5 completely covers the surface of the clay layer 4, playing an important role in isolating external pollutants and protecting the painting. The thickness difference between the two ensures that the integrity of the clay layer 4 is not affected when the painting is removed. By adjusting the adhesion between the clay layer 4 and the transparent protective film 5, the problem of delamination or tearing during the unstick process can be effectively prevented. Specifically, the material and process selection of the transparent protective film 5 is one of the key factors, which must ensure that it can effectively protect the internal structure and achieve the requirement of easy unstick.

[0061] In one embodiment, as shown in Figure 1 The edge of the transparent protective film 5 of the easy-to-unstick clay painting of the present application is provided with a sealing frame 11, which is tightly attached to the periphery of the bottom plate 1 to form a sealed chamber. This design effectively prevents external moisture and impurities from entering the chamber, ensuring the cleanliness of the clay painting. The sealing frame 11 further strengthens the edge structure, reduces the risk of tearing during the unstick process, and effectively prevents clay from being left on the bottom plate 1 or other surfaces. The sealing frame 11 is made of high-elasticity sealing material, ensuring that it can still maintain good sealing performance under long-term use or different environmental conditions.

[0062] The transparent protective film 5 covers the upper surface of the clay layer 4, and the two are connected by low-adhesion material to achieve the reusability of the clay painting after multiple unstickings. Specifically, the shape and size of the sealing frame 11 accurately correspond to the outer edge profile of the bottom plate 1, and the sealing treatment between the sealing frame 11 and the bottom plate 1 during installation adopts a special waterproof bonding process to ensure their close contact and reliable sealing. In this way, an effective barrier is formed between the clay layer 4 and the external environment, thereby further improving the protection effect and service life of the clay painting.

[0063] In actual operation, when the device is used, the base plate 1 can be placed at a position where the mud picture needs to be displayed. Then, the surface coated with the elastic glue layer 2 is laid on the base plate 1 with the surface facing upwards. Subsequently, the reinforcing fiber net 3 is inlaid into the elastic glue layer 2 to increase the strength and stability of the overall structure. After that, the prepared mud material is evenly applied on the upper surface of the elastic glue layer 2 to form a mud layer 4. Finally, the transparent protective film 5 is used to cover the mud layer 4, and low-adhesion material is used to connect the transparent protective film 5 and the mud layer 4, so as to facilitate subsequent removal.

[0064] When the mud picture needs to be removed for repositioning or preservation, the elastic glue layer 2 has flexibility and weak adhesion, so that the mud picture can be easily removed without leaving residues. At the same time, the transparent protective film 5 prevents external pollutants from contacting the mud layer 4, protecting the integrity and beauty of the mud layer 4. The reinforcing fiber net 3 further strengthens the firmness of the structure, avoiding tearing of the mud picture when it is removed. The whole process is simple and effective, solving the problem of residues left during the traditional mud picture removal, and realizing the effect of easy peeling and repeated use.

[0065] The exemplary systems and methods of the present application have been specifically illustrated and described herein with the foregoing preferred modes of carrying out the systems and methods. Those skilled in the art will realize that various changes can be made to the embodiments of the systems and methods described herein without departing from the spirit and scope of the application as defined in the appended claims.
