Description

Technical Field

[0001] The present invention relates to the technical field of architectural decoration material processing, and particularly to a processing method for cabinet boards. Background Art

[0002] Due to advantages such as low cost and strong stain resistance, tiles are widely used in the production of kitchen cabinets. When making tile cabinets, some tiles usually need to be stacked back-to-back (non-decorative surfaces in contact) and bonded together to form a whole cabinet board. However, there are some problems with this stacking method: there are gaps on the side edges (i.e., side surfaces) of the stacked tiles, and edge sealing treatment is required. The common edge sealing treatment method is to use a metal edge sealing strip to cover the side surface of the cabinet board where the overlapping gap is exposed to achieve the edge sealing effect. However, the cost of metal materials is relatively high, which is contradictory to the low-cost requirement of tile cabinets. Moreover, the metal edge sealing strip is usually directly clamped on the cabinet board, and there are gaps at the connection between it and the cabinet board, which are prone to dirt accumulation. In addition, protrusions (i.e., the side edges of the metal edge sealing strip) will be formed on the decorative surface of the cabinet board, affecting the overall aesthetics. Summary of the Invention

[0021] For the convenience of those skilled in the art, the present invention will be further described below in conjunction with embodiments and the accompanying drawings. The content mentioned in the embodiments does not limit the present invention.

[0022] Regarding the edge sealing problem of the outer side (side surface) of the cabinet board in the production of kitchen cabinets, this embodiment proposes a processing method with lower cost and better effect to reduce the comprehensive cost of cabinet production. Compared with the traditional metal strip edge sealing method, this embodiment adopts the processes of caulking and grinding, which not only makes the side surface of the cabinet board flat and beautiful, no longer exposing the overlapping gaps, but also avoids the problems of high cost, dirt accumulation, and protrusions affecting the aesthetics caused by the metal edge sealing strip, improving the overall aesthetics and cost-effectiveness of the cabinet.

[0023] Specifically, the processing method of the cabinet board in this embodiment (the process is shown in Figure 3 ) includes the following main steps: board lamination, gap treatment, board trimming, and painting treatment.

[0024] 1. Board lamination: Stack two boards 1 back to back (the non-decorative surfaces are in contact), and bond and fix them with a structural adhesive (such as neutral silicone structural adhesive) to form a complete cabinet board 2. This lamination method makes the decorative surfaces (such as the glaze of the tile) of the two boards 1 face outwards, avoiding the exposure of the non-decorative surfaces. Before lamination, it is recommended to roughen the bonding surface (the back of the tile) to enhance the bonding effect.

[0025] 2. Gap treatment: Use a caulking agent (such as epoxy-based caulking agent or cement caulking agent) to caulk the gaps on the side surface of the cabinet board 2 to form a flat surface. The caulking agent can be filled flush with the side surface of the cabinet board 2 or exceed the side surface of the cabinet board 2 to form a thin layer (for example, 0.1 - 0.3 mm thick). In addition, a caulking agent of the same color system as the side surface of the cabinet board 2 can be selected and its color can be adjusted to be close to that of the cabinet board 2 to achieve a better visual effect.

[0026] When performing the caulking treatment, it is recommended to dilute the caulking agent to a self-leveling state to improve its fluidity and uniformity. The self-leveling caulking agent can automatically fill the gaps, ensuring a flat surface and avoiding problems such as incomplete filling or uneven surface caused by excessive thickness. In addition, the self-leveling caulking agent can also reduce the difficulty of manual operation and improve the construction efficiency. Taking cement as the caulking agent as an example, the recommended water-cement ratio is 1:0.3.

[0027] This embodiment selects an epoxy-based caulking agent (epoxy-based caulking glue) as the caulking agent. Specifically, the epoxy-based caulking agent includes an epoxy resin main agent and a curing auxiliary agent, and the weight ratio of the two is 2:1 to 3:1.

[0028] In the epoxy-based caulking compound, the main epoxy resin agent, by mass parts, comprises the following components: 35-50 parts of epoxy resin, 5-10 parts of diluent, and 25-45 parts of filler A. Optionally, the main epoxy resin agent, by mass parts, further comprises the following components: 2-5 parts of pigment, and 0.1-0.3 parts of defoamer.

[0029] Among them, the epoxy resin can be selected from E-44 epoxy resin (low viscosity, suitable for thin-layer construction) or epoxy resin E-51 (suitable for high-strength scenarios), which is used to provide adhesion and chemical stability. The diluent can be selected from AGE (C12-14 alkyl glycidyl ether) or BGE (butyl glycidyl ether), which is used to reduce viscosity and improve workability. Filler A can be selected from the compounding of quartz powder (400 mesh) and silica powder (800 mesh) (3:1), or calcium carbonate (surface-treated), which is used to increase hardness and reduce shrinkage. The pigment can be selected from rutile titanium dioxide or iron oxide (complying with GB 24408), which is used for color adjustment (common colors are white, gray, and beige). The defoamer can be selected from non-silicon defoamers (such as BYK-052), which is used to prevent the generation of bubbles.

[0030] In the epoxy-based caulking compound, the curing auxiliary agent, by mass parts, comprises the following components: 15-35 parts of curing agent (such as modified amine curing agent), and 50-75 parts of filler B. Optionally, the curing auxiliary agent, by mass parts, further comprises the following components: 1-2 parts of coupling agent, and 0-15 parts of toughening agent.

[0031] Among them, the curing agent can be selected from modified amine curing agent T-31 (general-purpose) or IPDA (isophorone diamine) (for yellowing resistance requirements), which is used for room-temperature curing to balance speed and toughness. Filler B can be selected from calcium carbonate (low cost) or silica powder + boron nitride (for heat resistance requirements), which is used to adjust curing shrinkage and cost. The coupling agent can be selected from silane coupling agent KH-550 or epoxy-group-containing silane coupling agent KH-560, which is used to enhance the adhesion to tiles. The toughening agent can be selected from CTBN-modified epoxy toughening agent (general-purpose) or polyetheramine D230 (for heat-resistant scenarios), which is used to increase the flexibility of the colloid.

[0032] The following takes the main epoxy resin agent containing epoxy resin, diluent, filler A, pigment, and defoamer, and the curing auxiliary agent containing curing agent, filler B, coupling agent, and toughening agent as an example for further illustration. Among them, E-51 (high bonding strength) is selected as the epoxy resin, BGE (butyl glycidyl ether) is selected as the diluent, filler A is selected from quartz powder with a particle size of 400 mesh and silica powder with a particle size of 800 mesh, and they are compounded at a weight ratio of 3:1. Rutile titanium dioxide is selected as the pigment, and BYK-052 (non-silicon type) is selected as the defoamer. IPDA (isophorone diamine) is selected as the curing agent, silica powder + 3% boron nitride is selected as filler B, KH-560 (containing epoxy group) is selected as the coupling agent, and polyetheramine D230 is selected as the toughening agent.

[0033] Based on the above material selection, three epoxy-based sealants with different formulations were designed in this embodiment to meet different construction requirements: I. Sealant 1 (epoxy-based sealant) Ratio of main epoxy resin agent to curing auxiliary agent: 3:1 (by mass).

[0034] Main epoxy resin agent (by mass parts): 35 parts of epoxy resin + 5 parts of diluent + 25 parts of filler A + 2 parts of pigment + 0.1 part of defoamer.

[0035] Curing auxiliary agent (by mass parts): 15 parts of curing agent + 50 parts of filler B + 1 part of coupling agent, 0 part of toughening agent.

[0036] II. Sealant 2 (epoxy-based sealant) Ratio of main epoxy resin agent to curing auxiliary agent: 2.5:1 (by mass).

[0037] Main epoxy resin agent (by mass parts): 42.5 parts of epoxy resin + 7.5 parts of diluent + 35 parts of filler A + 3.5 parts of pigment + 0.2 part of defoamer.

[0038] Curing auxiliary agent (by mass parts): 25 parts of curing agent + 62.5 parts of filler B + 1.5 parts of coupling agent, 7.5 parts of toughening agent.

[0039] III. Sealant 3 (epoxy-based sealant) Ratio of main epoxy resin agent to curing auxiliary agent: 2:1 (by mass).

[0040] Main epoxy resin agent (by mass parts): 50 parts of epoxy resin + 10 parts of diluent + 45 parts of filler A + 5 parts of pigment + 0.3 part of defoamer.

[0041] Curing auxiliary agent (by mass parts): 35 parts of curing agent + 75 parts of filler B + 2 parts of coupling agent, 15 parts of toughening agent.

[0042] To evaluate the performance of these sealants, the curing time, tensile strength, and elongation at break of these sealants were tested according to the GB / T 528-2009 standard in this embodiment. The test results are as follows: Sealant 1: At 25°C, the curing time is 120 minutes, the tensile strength is 18 MPa, and the elongation at break is 5%.

[0043] Sealant 2: At 25°C, the curing time is 60 minutes, the tensile strength is 25 MPa, and the elongation at break is 15%.

[0044] Sealant Three: At 25°C, the curing time is 30 minutes, the tensile strength is 22 MPa, and the elongation at break is 30%.

[0045] From the test results, it can be seen that sealants with different formulations have their own characteristics in terms of curing time, tensile strength, and elongation at break. Sealant One has the longest curing time (120 minutes), and both the tensile strength and elongation at break are relatively low, which is suitable for scenarios where the requirement for curing time is not high. Sealant Two shows a relatively high tensile strength (25 MPa) and a moderate elongation at break (15%) within a shorter curing time (60 minutes), demonstrating good comprehensive performance and being suitable for most construction needs. Although Sealant Three has the shortest curing time (30 minutes), its tensile strength is slightly lower than that of Sealant Two, while its elongation at break is the highest (30%), indicating good flexibility and being suitable for scenarios that require rapid curing and have a high requirement for flexibility.

[0046] The above-mentioned sealants have waterproof and mildew-proof properties after curing, which can avoid the problem of water seepage at the joints of traditional edging strips. The viscosity of the sealant at 25°C is recommended to be controlled between 5000 - 15000 cps. The measured properties of the cured sealant (Sealant Three) are as follows: water absorption rate ≤ 0.05%; anti-mildew grade reaches 0; bond strength ≥ 3.5 Mpa; linear shrinkage rate ≤ 0.1%.

[0047] 3. Panel Finishing: The two side surfaces of the cabinet panel after caulking are polished to make them flat, improving the aesthetics and ensuring a smooth transition between the sealant and the surface of Panel 1.

[0048] The polishing process can not only improve the overall quality and aesthetics of Cabinet Panel 2 but also reduce subsequent construction problems caused by uneven sealant, lowering the construction difficulty and improving efficiency. Generally, it is only necessary to make the side surface of Panel 1 flat. However, for the convenience of subsequent painting, it is recommended to polish until at least part of the side surface of Panel 1 reveals the base material, forming a rougher texture to provide better adhesion for the painting material. The surface roughness after polishing should be controlled at Ra ≤ 1.6 μm to ensure sufficient adhesion and the flatness and smoothness of the surface.

[0049] 4. Painting Treatment: The paint is directly sprayed (sprayed, coated, or covered) on the two side surfaces of the polished cabinet panel 2 to cover the caulked area or the sealant layer covering the two side surfaces of the cabinet panel 2, further enhancing the aesthetics and practicality of the cabinet panel 2. In the selection of the painting material (paint), water-based paint can be used, such as water-based polyurethane paint.

[0050] Among them, the thickness of the painted surface can be controlled within the range of 0.1 - 1.0 mm, and different thickness ranges can be specifically selected according to actual needs. For example, for scenarios requiring a thin coating, the thickness can be controlled within 0.1 - 0.3 mm; for scenarios requiring a thicker coating to enhance the protection performance, the thickness can be controlled within 0.5 - 1.0 mm. After the paint is applied, a thin and continuous paint film can be formed on both side surfaces of the cabinet board 2, similar to the effect of an edge banding layer. This paint film can cover the non - decorative parts on both side surfaces of the cabinet board 2 and make the both side surfaces of the cabinet board 2 present an overall smooth surface, enhancing the integrity and aesthetics. Moreover, paint of the same color system as the decorative surface of the cabinet board 2 can be selected during painting. In this way, the paint film layer formed on both side surfaces of the cabinet board 2 can present a better overall effect with the two end surfaces (decorative surfaces) of the cabinet board 2, further enhancing the aesthetics.

[0051] The board 1 used in this embodiment includes, but is not limited to, ceramic and stone - like boards, preferably ceramic tile boards, such as glazed ceramic tiles.

[0052] The processing method provided in this embodiment is applicable to directly processing cabinet boards during cabinet manufacturing and also to batch pre - fabrication of cabinet boards.

[0053] During the processing of the cabinet board 2, either a single cabinet board 2 can be selected for processing or multiple cabinet boards 2 can be processed simultaneously. The specific operation method can be flexibly selected according to production requirements. When multiple cabinet boards 2 are processed simultaneously, they only need to be stacked in sequence, and after processing, the individual cabinet boards 2 can be separated. Since the smooth decorative surfaces of the cabinet boards 2 are in contact with each other during stacking and the gap between them is very small, even if caulking treatment is carried out, the amount of caulking agent entering the gap is very small, resulting in very little connection part (caulking agent) between the cabinet boards 2. Moreover, even if the caulking agent covers the side surfaces of the cabinet board 2, it is only a thin layer. Therefore, the separation process between the cabinet boards 2 is very easy and hardly affects the processed parts.

[0054] The gap treatment, board trimming, and painting treatment in this embodiment mainly target the side parts (the side facing the user) of the cabinet board 2 that are exposed after cabinet installation. These areas can be improved in aesthetics and practicality after treatment. For the areas that are not exposed after cabinet installation, the above - mentioned treatments are not required, thus saving time and cost.

[0055] After caulking, grinding, and painting treatment, the edge banding has good adhesion performance and durability, can effectively reduce the risk of cracking and peeling, and ensure the long - term stability and aesthetics of the product.

[0056] Figure 1 The structural schematic diagram of the board 1 used in this embodiment is shown. Figure 2 The structural schematic diagram of the cabinet board 2 processed using the board 1 is shown.

[0057] Figure 3 The processing flow of the cabinet board 2 is shown. Among them, Fig. (a) shows two selected boards 1; Fig. (b) shows the overlapping operation of the boards 1. It can be seen from the figure that there are relatively obvious gaps between the two overlapping boards 1; Fig. (c) presents the caulking and grinding treatment. Through this treatment step, the above-mentioned gaps are filled; Fig. (d) is the painting treatment, and a paint film is formed on the side surface of the cabinet board 2.

[0058] In terms of cabinet installation, this embodiment also conducts an optimized design to solve the stability and horizontal adjustment problems existing in the traditional cabinet board installation method.

[0059] The conventional cabinet board installation method is usually to stand it on a base pre-erected on the ground. However, there are some problems with this installation method. First, the inside of the base is usually suspended and lacks sufficient support structure, resulting in limited load-bearing capacity. Second, during the installation process, the cabinet board is usually directly stood on the base, and then it is fixed to the base and the board attached to the wall through an adhesive. This structure is not firm, making the cabinet board standing on the base lack stability and prone to tilting or displacement over time. In addition, since the cabinet board usually contacts the base surface with the entire bottom, it makes horizontal adjustment very inconvenient. During the installation process, the level of the base surface must be precisely adjusted when installing the base. If the pre-adjustment is improper, it will be very difficult to make adjustments later. And if the flatness of the bottom of the cabinet board is not good, it will also cause difficulty in adjusting the level of the cabinet board.

[0060] To solve the stability and horizontal adjustment problems existing in the traditional cabinet board installation method, this embodiment opens notches 3 (right-angled, i.e., right-angled notches) on both sides (front and back) of the bottom of the cabinet board 2. After the cabinet boards 2 are arranged at intervals, they are supported front and back by bottom support bars 4 standing on the ground (usually support bars made of the same material as the board 1), so that the notches 3 are located on the bottom support bars 4. The middle part of the bottom of the cabinet board 2 can directly contact the ground. This design not only provides better support effect, but also can easily achieve the horizontal adjustment of the entire cabinet board 2 by selecting two bottom support bars 4 with appropriate heights. Even if there is a gap between the middle part of the bottom of the cabinet board 2 and the ground, this gap is very small and only needs to be filled with some filling materials. The whole operation process is simple and efficient, and the stability of the structure is improved. Through the above method, even if the processing of the bottom of the cabinet board 2 is not flat enough, it will not affect the horizontal adjustment during cabinet installation, reducing the installation difficulty and improving the installation efficiency.

[0061] Of course, a groove with the same height as its notch 3 can be set at the middle position of the bottom of the cabinet board 2 for installing the bottom support bar 4 to further improve the support effect.

[0062] In the installation of traditional cabinets, the countertop is usually directly placed on the top of the cabinet board, and only supported by the cabinet boards on both sides, with most of the middle part hanging in the air, resulting in unsatisfactory bearing capacity of the countertop. Moreover, if the top of the cabinet board is not flat enough, it will also affect the horizontal adjustment of the countertop. In order to solve the above problems, this embodiment opens notches 3 (at right angles, i.e. right-angle notches) on both sides (front and back sides) of the top of the cabinet board 2, and installs the top support bar 6 (usually a support bar made of the same material as the board 1) in the notch 3, and its top is flush with the top of the cabinet board 2. Then place the countertop 5 on them. The top support bar 6 can be placed vertically in the notch 3 to play a better supporting role. The above design not only enhances the bearing capacity of the countertop 5, but also effectively disperses the pressure on the countertop 5 through a reasonable support structure, thereby improving the stability and service life of the overall cabinet. In addition, by selecting a top support bar 6 of a suitable height, the horizontality of the countertop 5 can be easily adjusted. Even if the top of the cabinet board 2 is not processed flat enough, it will not affect the horizontal adjustment during the installation of the cabinet, reducing the difficulty of installation and improving the installation efficiency. After adjusting the level, there may be a gap between the table top 5 and the top of the cabinet board 2, which can be filled with some filling materials to ensure the overall flatness and aesthetics.

[0063] Of course, a groove with the same height as the notch 3 can be provided at the middle of the top of the cabinet board 2 for installing the top support strip 6 to further enhance the support effect. In addition, since the top of the cabinet board 2 is usually untreated, a stopper 7 (such as a gasket) can be inserted into the top gap to abut against the side of the countertop 5 to achieve a stopper fixation effect.

[0064] In addition, the notches 3 and the grooves provided at the top and bottom of the cabinet board 2 can be pre-cut before the board 1 is stacked, as shown in FIG. Figure 1 , 2 .

[0065] Figure 4 FIG. 2 shows an exploded view of a cabinet installed using the cabinet panel 2 of this embodiment. Figure 5 The schematic diagram of the structure after the cabinet is assembled is shown.

[0066] In this embodiment, caulking treatment is carried out on the gaps on the side surfaces of the cabinet board 2, and the side surfaces after caulking are polished, which improves the aesthetics of the side surfaces of the cabinet board 2. The caulking treatment and polishing process make the gaps on the side surfaces of the cabinet board 2 be filled smoothly, the overall appearance is improved, the exposure of overlapping gaps is avoided, and the problem of dirt accumulation is effectively solved. Compared with the traditional metal strip edge-sealing method, the edge-sealing treatment method adopted in this embodiment has lower cost, reduces the cabinet manufacturing cost, and at the same time avoids the problems of high cost, dirt accumulation and protrusions affecting aesthetics caused by the metal edge-sealing strip. The caulking and polishing processes are simple and easy to implement, with high efficiency, which helps to shorten the cabinet manufacturing cycle.

[0067] After the painting treatment, the edge-sealing layer on the side surface of the cabinet board 2 is integrated with the cabinet board 2, forming a good edge-sealing effect, and problems such as cracking, peeling and falling off are not likely to occur. Moreover, the edge-sealing layer and the decorative surface at the end face of the cabinet board 2 achieve a better three-dimensional effect of integrity, further improving the aesthetics. The cabinet board 2 processed by this edge-sealing method has the advantages of beauty, practicality, low cost and batch production, and can be widely applied to kitchen cabinets, bathroom cabinets in the bathroom, mirror cabinets, washing machine cabinets and other products used in humid spaces.

[0068] The above is only the preferred embodiment of the present invention, and does not impose any form of limitation on the present invention. Although the present invention has been disclosed as the preferred embodiment above, it is not intended to limit the product form and style of the present invention. Any person skilled in the art can make some changes or modifications to the above-disclosed technical content to form an equivalent embodiment with equivalent changes within the scope of the technical solution of the present invention. However, as long as the content does not depart from the technical solution of the present invention, it still belongs to the patent scope of the technical solution of the present invention.
