Description

Technical Field

[0001] This invention relates to a foamed wall panel, and more particularly to an elastomer-coated foamed wall panel; it belongs to the technical field of wood-plastic composite wall panels. Background Technology

[0002] Wall panels are divided into interior and exterior wall panels. Interior wall panels are mainly made of solid wood, though some are wood-plastic composites; while exterior wall panels are primarily made of wood-plastic composites. Besides protecting the wall structure, they also serve a decorative purpose. However, existing wood-plastic composite wall panels are relatively heavy, making transportation and installation inconvenient. Lightweight wall panels, such as PVC foam, are also available. However, the main problem with PVC foam wall panels is their low mechanical properties; although not load-bearing components, they are still prone to bending or breaking.

[0003] Some existing technologies employ fiberglass reinforcement structures to increase the structural strength of PVC foam materials, thereby improving strength and alleviating warping and deformation problems. For example, patent application number CN202122137484.2 discloses a PVC foam board, which is composed of multiple PVC foam core materials laid out and assembled. Each pair of adjacent PVC foam core materials is bonded and fixed together by an adhesive layer. The adhesive layer is a fiberglass cloth with an adhesive coating on the surface.

[0004] Chinese patent application CN116061526A discloses a fiber-reinforced PVC foam wall panel. This wall panel is an irregularly shaped panel. Besides the panel itself, the mounting surface of the panel also includes a male-side support, a support member, and a female-side support. The male-side support has a locking head, the female-side support has a locking groove and a first mating end, and the support member has a support portion and an abutment portion. Due to the unique structure of each component, the outer contour of the wall panel's mounting surface is very irregular, which leads to difficulties in extrusion production. Furthermore, the installation of this wall panel requires nailing, specifically using spray nails on the decorative surface. Because the surface of the wall panel is made of an elastomer material with a self-healing function, after the spray nails are driven in, the decorative surface will return to its original shape shortly afterward, making the nails virtually undetectable without special attention. This allows for a simple, straightforward, and convenient installation method. However, this installation method also causes a lot of trouble when a wall panel is damaged and needs to be repaired or replaced, or when the homeowner needs to change the decoration style. Summary of the Invention

[0005] To address the aforementioned problems, this invention provides an elastomer-coated foamed wall panel. This invention divides the wall panel into two parts: the main body is made of PVC foam extrusion and reinforced with reinforcing sheets, resulting in a regular structure that facilitates extrusion production; the mounting plate part is made of PVC or polyolefin through conventional extrusion, improving strength while also facilitating extrusion production.

[0006] The technical solution of the present invention to solve the above problems is as follows:

[0007] An elastomer-coated foamed wall panel includes a main wall panel and a mounting plate disposed at both ends of the main wall panel and connected thereto. At least one side of the mounting plate is provided with a mounting groove for accommodating the end of the main wall panel. The main wall panel includes a reinforcing sheet, a rigid PVC foam core, and an elastomer coating layer covering at least the decorative surface of the rigid PVC foam core. The reinforcing sheet is disposed at the internal center of the rigid PVC foam core.

[0008] In the above technical solution of the present invention, the reinforcing sheet is disposed in the inner center of the rigid PVC foam core, which means that the upper and lower surfaces of the reinforcing sheet in contact with the rigid PVC foam core are approximately parallel to the upper and lower surfaces of the rigid PVC foam core, and the reinforcing sheet is disposed in the central region of the rigid PVC foam core in the thickness direction.

[0009] In the above-described technical solution of this invention, the thermal stability of the reinforcing sheet needs to be stronger than that of the PVC material. Therefore, the engineering plastic constituting the reinforcing sheet in this application should be a type with a glass transition temperature higher than that of PVC resin. This is because it is necessary to composite the molten PVC foaming material with the reinforcing sheet, and the processing temperature of PVC is usually 160~170°C. At this temperature, the reinforcing sheet should not soften or should only soften slightly. Therefore, the melting point of the engineering plastic in the reinforcing sheet should not be lower than 160°C to ensure that the molten PVC foaming material, after being coated on the reinforcing sheet, will not re-enter the molten state and cause deformation of the reinforcing sheet. Materials that can be used for the reinforcing sheet include AS, ABS, etc.

[0010] The invention was initially developed to address the issue of bulky wall panels, while also considering cost reduction. To reduce overall weight and production costs, PVC foaming was used; however, this significantly reduced the panel's strength. This was addressed by adding an internal reinforcing sheet process. However, this internal reinforcing sheet process is very difficult for wall panels with irregular surfaces. This invention employs a split approach, dividing the traditional wall panel into two parts: the main body wall panel, which constitutes the largest area; and a mounting plate, distributed at the mounting end of the main wall panel, used to fix the main wall panel to the wall. The main body is shaped into a regular form, reinforced with PVC foam and reinforcing sheets. Its regular structure facilitates extrusion production. The mounting plate is made using conventional extrusion of PVC or polyolefin, which facilitates extrusion production while also improving strength.

[0011] As a preferred embodiment of the above technical solution, the mounting plate further includes a slot for inserting a hook for mounting a clip.

[0012] As a preferred embodiment of the above technical solution, the slot includes a horizontal insertion part and a vertical hooking part; the height of the insertion part is not less than the height of the hook; the width of the hooking part is 0.01~0.2mm greater than the thickness of the hook.

[0013] In the above technical solution of the present invention, the mounting plate is a single-unit structure, and its length direction is parallel to the ground direction, making it suitable for horizontally assembled wall panels. That is, the wall panel is hung or clipped onto the mounting plate, and the weight of the wall panel is borne by the mounting plate.

[0014] As another preferred embodiment of the above technical solution, the mounting plate is formed by joining a convex end splicing strip and a concave end splicing strip, and the convex end splicing strip and the concave end splicing strip form the mounting groove after joining.

[0015] In the above technical solution of the present invention, the clamping plate is a split-type splicing structure, and the splicing seam between the convex end splicing strip and the concave end splicing strip is perpendicular to the ground, which is suitable for vertically assembled wall panels. That is, the clamping plate only provides constraint force, and the weight of the wall panel is not borne by the clamping plate.

[0016] As a further preferred embodiment of the above technical solution, one end of the convex splicing strip is provided with a tenon for connecting the groove, and the other end is provided with a first mounting groove for connecting the first end of the main wall panel; one end of the concave splicing strip is provided with a groove for connecting the tenon, and the other end is provided with a second mounting groove for connecting the second end of the main wall panel; the width of the groove is equal to the sum of the thickness of the tenon and the hook; the length of the tenon is not greater than the depth of the groove.

[0017] As a preferred embodiment of the above technical solution, the reinforcing sheet is provided with a plurality of uniformly distributed through holes that penetrate the reinforcing sheet in terms of thickness.

[0018] In the above-described technical solution of the present invention, in order to improve the bonding strength of the reinforcing sheet within the rigid PVC foam core, through holes are provided on the reinforcing sheet. This allows the materials on both sides of the reinforcing sheet to form a whole, rather than being separated by the reinforcing sheet. Therefore, the bonding between the reinforcing sheet and the rigid PVC foam core can be significantly improved.

[0019] As a preferred embodiment of the above technical solution, the main wall panel includes a wall panel body and decorative protrusions protruding from the outer surface of the wall panel body.

[0020] In the above technical solution of the present invention, decorative protrusions are formed on the outer surface of the main wall panel, and the outer surface of the mounting plate is equally spaced with the decorative protrusions. In terms of visual effect, the decorative protrusions on the outer surface of the mounting plate are almost identical, so that although the foamed wall panel of the present invention is a split type, it has the advantage of good integrity.

[0021] As a further preferred embodiment of the above technical solution, the reinforcing sheet includes a reinforcing sheet body and a vertical reinforcing sheet corresponding to the decorative protrusion.

[0022] In the above technical solution of the present invention, the reinforcing sheet body supports the main wall panel, and the vertical reinforcing sheet provides support for the decorative protrusion.

[0023] As a further preferred embodiment of the above technical solution, the main wall panel also includes a pad protrusion protruding from the inner surface of the wall panel body.

[0024] After the main wall panel and the mounting plate are assembled, a certain gap is formed between the back of the main wall panel and the wall surface. This gap prevents direct contact between the wall surface and the wall panel, hindering the conduction of moisture and heat, and providing a certain degree of sound insulation and moisture-proofing. However, when external forces are applied to the wall panel, due to the existence of the gap, the back of the wall panel is not supported, and the wall panel cannot directly transfer the force to the wall, but rather bears the force almost entirely, increasing the possibility of damage to the wall panel. The presence of the padding protrusions, on the other hand, can directly transfer the force to the wall even with slight deformation of the wall panel, improving the wall panel's resistance to sudden external mechanical forces.

[0025] As a further preferred embodiment of the above technical solution, the reinforcing sheet includes a reinforcing sheet body and a vertical support sheet corresponding to the pad protrusion.

[0026] In the above technical solution of the present invention, the vertical support piece provides support for the pad protrusion.

[0027] Another object of the present invention is to provide a method for preparing the above-mentioned wall panel.

[0028] A method for preparing an elastomer-coated foamed wall panel includes the following steps:

[0029] S1. The reinforcing sheet material is melted through the first extruder and then extruded into the main channel of the die;

[0030] S2. In the material conveying direction, the temperature of the molten material in the main channel gradually decreases and is pre-formed to form the reinforcing sheet;

[0031] S3. After the raw material of rigid PVC foam core is melted through the second extruder, it is extruded into the mold through the side channel. In the mold, the raw material of rigid PVC foam core covers the reinforcing sheet. After being extruded from the mold opening, it is cooled and shaped to obtain the self-skinning main wall panel precursor.

[0032] S4. Place the main wall panel front body into the mold containing the polyurethane composite material, so that the polyurethane composite material at least submerges the decorative surface of the main wall panel front body.

[0033] S5. Close the mold, maintain the pressure inside the mold, and after the polyurethane has cured, open the mold and remove the main wall panel. After trimming, the main wall panel is obtained.

[0034] S6. The raw material of the card plate is melted through the second extruder and extruded into the second mold. After being extruded from the opening of the second mold, it is cooled and shaped to obtain the card plate.

[0035] In the above technical solution of the present invention, polyurethane composite material refers to the material after polyurethane AB materials have been mixed evenly.

[0036] In summary, the present invention has the following beneficial effects:

[0037] 1. This invention divides the wall panel into two parts. The main body is made of PVC foam extrusion and reinforced with reinforcing sheets, resulting in a regular structure that is convenient for extrusion production. The mounting plate part is made of PVC or polyolefin through conventional extrusion, which improves strength and also facilitates extrusion production.

[0038] 2. The present invention has a simple structure. The main wall panel and the mounting plate are connected by a tenon and groove joint, which is convenient for installation. The mounting plate is connected to the clips fixed to the wall by a snap fastener, which is also convenient for installation.

[0039] 3. The main wall panel of this invention has a gap between itself and the wall surface, which can block the conduction of moisture and heat, and has a certain sound insulation and moisture-proof effect; at the same time, the presence of the padding protrusion can directly transfer the force to the wall when the wall panel is slightly deformed, which improves the wall panel's resistance to sudden external mechanical forces.

[0040] 4. Decorative protrusions are formed on the outer surface of the main wall panel, and the outer surface of the mounting plate is equally spaced with the decorative protrusions. Visually, the outer surface of the mounting plate and the decorative protrusions are almost identical, so that although the foamed wall panel of the present invention is a split type, it still has the advantage of good integrity.

[0055] The present invention will be further explained and described below with reference to the accompanying drawings.

[0056] This specific embodiment is merely an explanation of the present invention and is not intended to limit the invention. Any changes made by those skilled in the art after reading this specification, as long as they fall within the scope of the claims, will be protected by patent law. Example 1

[0057] Figure 1 The diagram shown is an installation schematic of the foamed wall panel in this embodiment.

[0058] The specific structure of the wall panel is as follows: Figure 2 As shown.

[0059] An elastomer-coated foamed wall panel, comprising:

[0060] -Main wall panel 01, with two ends;

[0061] - Mounting plate 02 is located at the end of the main wall panel 01 and is connected to it.

[0062] from Figures 1-2 It can be seen that the wall panels are installed horizontally; and the main wall panel 01 is installed onto the wall by means of a clip plate 02.

[0063] The specific structure of the main wall panel 01 is as follows: Figure 2 As shown, from a manufacturing perspective, it includes:

[0064] -Enhanced film 011;

[0065] - Rigid PVC foam core 012;

[0066] - Elastomer overlay 013, covering the decorative surface of the rigid PVC foam core 012.

[0067] The reinforcing sheet 011 is horizontally disposed at the center of the rigid PVC foam core 012. More specifically, the upper and lower surfaces of the reinforcing sheet 011 in contact with the rigid PVC foam core 012 are approximately parallel to the upper and lower surfaces of the rigid PVC foam core 012, and the reinforcing sheet 011 is disposed in the central region of the rigid PVC foam core 012 in the thickness direction.

[0068] From an installation perspective, the main wall panel 01 includes:

[0069] -The wall panel body 01-1 has two ends;

[0070] - Decorative protrusion 01-2 is set on the decorative surface of the wall panel body 01-1;

[0071] - Padding protrusion 01-3 is set on the back surface of wall panel body 01-1.

[0072] from Figure 1 It can be seen that decorative protrusions 01-2 are formed on the outer surface of the main wall panel 01, and the outer surface of the mounting plate 02 is equally spaced with the decorative protrusions. Visually, the decorative protrusions 01-2 on the outer surface of the mounting plate 02 are almost identical.

[0073] The specific structure of the card plate 02 is as follows: Figure 3 As shown. The mounting plate 02 includes:

[0074] -Card mounting plate body;

[0075] - Mounting groove 021 is provided at the upper or lower end of the mounting plate body. In this embodiment, it includes a first mounting groove 021-1 at the upper end and a second mounting groove 021-2 at the lower end; the mounting groove 021 is for the end of the main wall panel 01 to be inserted.

[0076] Furthermore, the inner side of the mounting plate body has a slot 022. The inner side refers to the side closest to the wall surface. The slot 022 includes a horizontal insertion part 022-1 and a vertical hook part 022-2. The height of the insertion part 022-1 is slightly greater than the height of the hook 031 for installing the clip 031, to facilitate installation; the width of the hook part 022-2 is 0.02mm greater than the thickness of the hook 031, to prevent the hook 031 from wobbling when inserted into the hook part 022-2.

[0077] The above-mentioned wall panel preparation method includes the following steps:

[0078] S1. The reinforcing sheet material (ABS) is melted through the first extruder and extruded into the main channel of the die;

[0079] S2. In the material conveying direction, the temperature of the molten material in the main channel gradually decreases and is pre-formed to form the reinforcing sheet;

[0080] S3. After the raw material of rigid PVC foam core is melted through the second extruder, it is extruded into the mold through the side channel. In the mold, the raw material of rigid PVC foam core covers the reinforcing sheet. After being extruded from the mold opening, it is cooled and shaped to obtain the self-skinning main wall panel precursor.

[0081] S4. Place the main wall panel front body into the mold containing the polyurethane composite material, so that the polyurethane composite material at least submerges the decorative surface of the main wall panel front body.

[0082] S5. Close the mold, maintain the pressure inside the mold, and after the polyurethane has cured, open the mold and remove the main wall panel. After trimming, the main wall panel is obtained.

[0083] S6. The raw material of the card plate is melted through the second extruder and extruded into the second mold. After being extruded from the opening of the second mold, it is cooled and shaped to obtain the card plate.

[0084] The polyurethane composite material mentioned above refers to the material after polyurethane AB materials have been mixed evenly.

[0085] The specific installation method in this embodiment is as follows:

[0086] 1) First, fix the clip 03 to the wall; the clip 03 is divided into several height layers, with several evenly distributed in each height layer; the hook 031 of the clip 03 is set to face upwards;

[0087] 2) Position the first mounting slot 021-1 of the mounting plate 02 upwards, and keep the mounting plate body perpendicular to the ground; starting from the bottom, install the first mounting plate 02:

[0088] Align the insertion part 022-1 of the mounting plate 02 with the hook 031, and then push the mounting plate 02 towards the wall until the back of the mounting plate 02 contacts the wall mounting surface of the mounting clip 03; push the mounting plate 02 down so that the hook 031 is fully embedded in the hanging part 022-2; complete the installation of the first mounting plate 02.

[0089] 3) Pre-install the first main wall panel 01:

[0090] Place the lower end of the main wall panel 01 into the first mounting groove 021-1 of the first mounting plate 02; gently tap the main wall panel 01 downwards to make the main wall panel 01 basically wedge into the first mounting groove 021-1; keep the main wall panel 01 basically perpendicular to the ground; complete the initial fixing of the first main wall panel 01.

[0091] 4) Install the second mounting plate 02 and fix the first main wall panel 01:

[0092] like Figure 4 As shown, gently pry the upper end of the first main wall panel 01 away from the wall surface to make it deflect slightly. At the same time: ① Align the second mounting groove 021-2 of the second mounting plate 02 with the upper end of the first main wall panel 01.

[0093] ② Align the insertion part 022-1 of the second mounting plate 02 with the hook 031;

[0094] Then, the second mounting plate 02 and the first main wall panel 01 are slowly returned to their original positions as a whole, forming a shape as shown. Figure 5 The state shown is that the first main wall panel 01 is upright and the second mounting plate 02 is installed in the horizontal direction.

[0095] Finally, gently tap the second mounting plate 02 downwards to make:

[0096] The lower end of the first main wall panel 01 is fully wedged into the first mounting groove 021-1 of the first mounting plate 02;

[0097] The upper end of the first main wall panel 01 is completely wedged into the second mounting groove 021-2 of the second mounting plate 02;

[0098] Complete the installation of the first main wall panel 01 and the second mounting plate 02;

[0099] 5) Pre-install the second main wall panel 01;

[0100] 6) Install the third mounting plate 02 and fix the second main wall panel 01;

[0101] Repeat the above process until all the mounting plates 02 and main wall panels 01 are installed in place.

[0102] Finally, it should be noted that there will be a gap of about 0.5cm between the top mounting plate 02 and the ceiling. This gap can be resolved by embedding a caulking strip in the first mounting groove 021-1. This is easy for those skilled in the art to implement, so it will not be described in detail here.

[0103] It should also be noted that, in order to ensure the firmness of the installation while also taking into account the ease of installation, in the above technical solution of the present invention, the depth of the first mounting groove 021-1 is greater than the depth of the second mounting groove 021-2. For example... Figures 3-5 As shown, the depth of the first mounting groove 021-1 is approximately twice that of the second mounting groove 021-2. If the second mounting groove 021-2 is too deep, installation will be inconvenient; if the first mounting groove 021-1 is too shallow, the fixing strength will be insufficient. Simultaneously, the depth of the first mounting groove 021-1 is related to whether the upper end of the main wall panel 01 can be slightly pried off the wall surface in step 4) above. Therefore, the depth of the first mounting groove 021-1 cannot be too deep. Considering the above, the depth of the first mounting groove 021-1 can be designed to be 1.0~4.0cm; the depth of the second mounting groove can be designed to be 0.5~2.0cm. In this embodiment, the depth of the first mounting groove 021-1 is 2.0cm, and the depth of the second mounting groove is 1.2cm. Example 2

[0104] Figure 6 The diagram shown is an installation schematic of the foamed wall panel in this embodiment.

[0105] The structure of the wall panel is as follows Figure 7 As shown.

[0106] An elastomer-coated foamed wall panel, comprising:

[0107] -Main wall panel 01, with two ends;

[0108] - Mounting plate 02 is located at the end of the main wall panel 01 and is connected to it.

[0109] from Figures 6-7 It can be seen that the wall panels are installed vertically; and the main wall panel 01 is installed onto the wall via a clip-on plate 02. From Figures 6-7 It can be seen that decorative protrusions 01-2 are formed on the outer surface of the main wall panel 01, and the outer surface of the mounting plate 02 is equally spaced with the decorative protrusions. Visually, the decorative protrusions 01-2 on the outer surface of the mounting plate 02 are almost identical.

[0110] The specific structure of the main wall panel 01 is the same as that in Example 1, so it will not be described again.

[0111] The specific structure of the card plate 02 is as follows: Figure 8 As shown. The mounting plate 02 is formed by joining a convex end splicing strip 02-1 and a concave end splicing strip 02-2. After joining, the convex end splicing strip 02-1 and the concave end splicing strip 02-2 form the mounting groove 022.

[0112] like Figure 8 As shown, one end of the convex splicing strip 02-1 is provided with a tenon for connecting the groove, and the other end is provided with a first mounting groove 021-1 for connecting the first end of the main wall panel. One end of the concave splicing strip 02-2 is provided with a groove for connecting the tenon, and the other end is provided with a second mounting groove 021-2 for connecting the second end of the main wall panel. The width of the groove is equal to the sum of the thickness of the tenon and the hook 031. The length of the tenon is not greater than the depth of the groove.

[0113] The installation method in this embodiment is existing technology, so it will not be described in detail here.
