Description

Technical Field

[0001] The invention relates to a layered high-density fiberboard with an anti-deformation function, and in particular to a layered high-density fiberboard with an anti-deformation function applied in the technical field of layered products. Background Art

[0002] Layered high-density fiberboard has been widely used in furniture, building materials and other fields due to its excellent physical and mechanical properties and environmental protection characteristics. However, layered high-density fiberboard is prone to deformation during use, especially in a humid environment. This is mainly due to the hygroscopic expansion characteristics of the fiberboard itself. In addition, improper storage and transportation methods may also cause fiberboard deformation. These deformation problems not only affect the performance and aesthetics of the fiberboard, but also shorten its service life, causing losses to both manufacturers and users. Therefore, how to effectively prevent the deformation of layered high-density fiberboard has become a technical problem that needs to be urgently solved in this field.

[0003] The specification of Chinese invention patent CN111315578B discloses a decorative panel with a carrier plate, which includes a multi-layer plastic carrier material with N ABA-type layer sequences, wherein layer A includes a first thermoplastic resin, layer B includes a second thermoplastic resin different from the thermoplastic resin of layer A, and wherein N is between greater than or equal to 3 and less than or equal to 250. This design improves the physical properties of the decorative panel to a certain extent and improves its deformation resistance by reasonably selecting different thermoplastic resins. However, this patent mainly targets plastic-based decorative panels, and there is still a lack of effective solutions to the deformation problem of layered high-density fiberboards.

[0004] The specification of Chinese invention patent CN104401078B discloses a multi-layer polylactic acid composite sheet and its preparation method. The composite sheet consists of a three-layer structure: the first layer is an impact-resistant toughened polylactic acid composite layer, the second layer is a high-performance fiber-reinforced polylactic acid composite layer, and the third layer is an impact-resistant toughened polylactic acid composite layer. The three-layer structure of the composite sheet of the present invention is prepared separately and formed after hot rolling. The composite sheet has the characteristics of high modulus, high strength, high toughness and biodegradability, and its outer layer can adjust the hardness as needed. Although this multi-layer composite structure improves the mechanical properties of the sheet to a certain extent, it has limited effect on preventing the deformation of layered high-density fiberboard, and the polylactic acid material used in the patent is relatively expensive, which is not conducive to large-scale promotion and application.

[0005] Although the above patents have made useful attempts to improve the performance of the board materials, there are still certain limitations in solving the deformation problem of layered high-density fiberboard. They mainly focus on material modification and multi-layer composite, but ignore the influence of the environment in which the fiberboard is used. In fact, most of the deformation of layered high-density fiberboard occurs in a humid environment. It is difficult to fundamentally solve the problem by relying solely on material modification. In addition, the existing technology also does not give sufficient consideration to the deformation protection of fiberboard during storage and transportation. Summary of the invention

[0006] In view of the above-mentioned prior art, the technical problem to be solved by the present invention is the problem of preventing the layered high-density fiberboard from being deformed in a humid environment and during storage and transportation.

Dovetail grooves matching the dovetail tenons are provided at the corresponding positions of the corner blocks and the dovetail tenons, and the dovetail tenons are slidably connected with the dovetail grooves. The transverse frame bars and the longitudinal frame bars are made of aluminum alloy.

[0009] As a further improvement of the present application, the hygroscopic layer is made of a hygroscopic material, the unidirectional air-conducting layer is made of a material with unidirectional air permeability, and the air permeability direction is from the hygroscopic layer to the wicking layer.

[0010] As a further improvement of the present application, the siphon layer is made of a hydrophilic polymer film, the heat collecting layer is a hollow structure, and one third of the space in the hollow part is filled with liquid ammonia.

[0011] As another improvement of the present application, a porous metal layer is fixedly connected to the inner wall of the heat collecting layer, the heat collecting layer is made of copper alloy, the evaporation layer is made of porous ceramic, and a through hole penetrating the evaporation layer is opened in the center of the evaporation layer.

[0012] As another improved supplement of the present application, sliding grooves matching with the upper brush plate and the lower brush plate are opened at corresponding positions of the transverse frame strip and the upper brush plate and the lower brush plate, and the upper brush plate and the lower brush plate are slidably connected with the sliding grooves on the transverse frame strip.

[0013] As another improvement supplement of the present application, a coating port is provided at one end of the upper brush plate and the lower brush plate close to each other, and a paint groove for accommodating waterproof paint is provided in the upper brush plate and the lower brush plate, and the paint groove is connected to the coating port.

[0014] As another improvement of the present application, a through groove is provided at a position of the corner block corresponding to the evaporation layer, and one end of the through groove away from the evaporation layer is connected to the external space.

[0015] The dovetail tenon is fixedly connected to the corresponding transverse frame strips and longitudinal frame strips through a plurality of bolts, and the corner pressure plate is fixedly connected to the corner block through bolts.

[0016] In summary, this application has the following beneficial effects: 1. The frame structure effectively suppresses the deformation of the fiberboard. The present invention adopts a frame structure composed of horizontal frame strips, vertical frame strips and corner blocks to physically restrain and reinforce the layered high-density fiberboard. The frame structure fits tightly to the surface of the fiberboard. When the fiberboard is subjected to external force or expands due to moisture absorption, it can effectively suppress its deformation and keep the shape of the fiberboard stable.

By adjusting the degree of fit between the brush plate and the surface of the fiberboard, an appropriate pre-tightening force can be applied to the fiberboard to actively prevent it from deformation. At the same time, a paint groove is provided inside the brush plate to repair the waterproof coating on the surface of the fiberboard and extend the service life of the fiberboard.

[0020] 5. Systematic dehumidification design effectively solves the problem of moisture absorption and deformation of fiberboard. The present invention designs a set of systematic dehumidification devices in the frame structure, including a moisture absorption layer, a one-way guide layer, a siphon layer, a heat collection layer and an evaporation layer. Each layer efficiently discharges the moisture in the fiberboard in the order of moisture absorption, moisture conduction, heating and evaporation, fundamentally solving the deformation problem of the fiberboard caused by moisture absorption.

[0021] 6. The heat collecting layer utilizes ambient heat, which is energy-saving and environmentally friendly. The heat collecting layer adopts a hollow structure, is filled with liquid ammonia, and has a porous metal inner wall. This design enables the heat collecting layer to effectively absorb ambient heat and quickly transfer the heat to the evaporation layer, accelerating water evaporation without the need for additional energy input, which is in line with the concept of energy conservation and environmental protection.

[0022] 7. The thermal insulation layer ensures the dehumidification efficiency. The thermal insulation layer is set between the heat collecting layer and the siphon layer, as well as on the outside of the heat collecting layer and the evaporation layer. The thermal insulation layer is made of materials with excellent thermal insulation performance, which can minimize the heat loss of the heat collecting layer and the evaporation layer, ensure that the collected heat is efficiently used for water evaporation, and improve the dehumidification efficiency.

[0025] Three implementation modes of the present application are described in detail below with reference to the accompanying drawings.

[0026] Example 1

[0027] This embodiment provides a layered high-density fiberboard with an anti-deformation function, such as Figures 1 to 12 As shown, it includes a layered high-density fiberboard body, the outer end of the layered high-density fiberboard body is clamped with symmetrically arranged transverse border strips 1 and longitudinal border strips 2, a corner block 3 is provided between two adjacent transverse border strips 1 and longitudinal border strips 2, both ends of the transverse border strips 1 and the longitudinal border strips 2 are fixedly connected with dovetail tenons 4, and dovetail grooves 5 matching with the dovetail tenons 4 are provided at corresponding positions of the corner blocks 3 and the dovetail tenons 4, the dovetail tenons 4 are slidably connected to the dovetail grooves 5, and the symmetrically arranged upper brush plates 6 and lower brush plates 7 are slidably connected between the symmetrically arranged transverse border strips 1.

[0028] Among them, the horizontal border strips 1 and the vertical border strips 2 are made of lightweight and high-strength aluminum alloy material, fit tightly with the layered high-density fiberboard body, and are firmly fixed to the outer end of the fiberboard body by snap-fitting. The horizontal border strips 1 and the vertical border strips 2 form a stable frame structure around the fiberboard body, which can effectively restrain the deformation of the fiberboard body.

[0029] A special corner block 3 is provided at the connection between the horizontal border strip 1 and the vertical border strip 2. The corner block 3 plays a role of connection and reinforcement, making the connection between the border strips more firm, while also improving the overall rigidity and stability of the border.

[0030] In order to realize the detachable connection between the transverse border strip 1 and the longitudinal border strip 2 and the corner block 3, dovetail tenons 4 are designed at both ends of the border strips, which are matched with dovetail grooves 5 provided on the corner block 3. The dovetail tenons 4 and the dovetail grooves 5 are connected by sliding, which is convenient for installation and disassembly. At the same time, the dovetail tenon structure also provides better positioning and fixing effects, making the connection not easy to loosen.

[0031] An upper brush plate 6 and a lower brush plate 7 are installed between two opposite transverse border strips 1, which are symmetrical in shape. The upper brush plate 6 and the lower brush plate 7 are also slidably connected to the transverse border strip 1, and their positions can be adjusted by sliding in the length direction of the transverse border strip 1.

[0032] The above structure forms a "frame + brush plate" anti-deformation device, which can prevent the layered high-density fiberboard from deformation in many aspects: The frame structure formed by the frame strips 1 and 2 physically restrains and reinforces the fiberboard body, preventing it from bending and deforming.

[0033] The corner blocks 3 and the dovetail tenon 4 further enhance the rigidity and stability of the frame structure, enabling it to better play a restraining role.

[0034] The upper brush plate 6 and the lower brush plate 7 can be slidably adjusted in the length direction of the frame strip 1. According to the stress condition of the fiberboard, appropriate pre-tightening force is applied to balance the external force on the fiberboard to prevent its deformation.

[0035] The upper brush plate 6 and the lower brush plate 7 also play a supporting and fixing role with the fiberboard body, preventing the fiberboard from thickness deformation in a direction perpendicular to the board surface.

[0036] In actual use, first fix the frame strips 1 and 2 around the fiberboard body by snapping, then use the corner blocks 3 to connect the frame strips into a complete frame, then install the upper brush plate 6 and the lower brush plate 7 between the two opposite transverse frame strips 1, and adjust the position of the brush plate as needed to make it fit tightly with the fiberboard body and apply appropriate preload.

[0037] When the fiberboard is subjected to external force, the frame structure and brush plate can effectively restrain its deformation and control the deformation within a very small range. Even in a humid environment, the deformation caused by the fiberboard absorbing water and expanding can be effectively suppressed.

[0038] Compared with the prior art, the anti-deformation structure provided in this embodiment has the following beneficial effects: The combination of frame structure and brush plate is adopted to restrain the fiberboard from multiple dimensions and has good anti-deformation effect.

[0039] Reasonable material selection, the frame strips are made of aluminum alloy, which is light and high-strength, and can play a good reinforcement role without significantly increasing the overall weight of the fiberboard.

[0040] The design of the corner block 3 and the dovetail tenon 4 makes the connection of the frame structure more reliable, has good stability, and is easy to install and disassemble.

[0041] The brush plate adopts a sliding connection method, which can flexibly adjust the position to adapt to different stress conditions and achieve active anti-deformation.

[0042] The overall structure is simple, the manufacture and installation are relatively convenient, the cost is relatively low, and it has good prospects for promotion and application.

[0043] This embodiment can effectively prevent the layered high-density fiberboard from being deformed through the organic combination of the frame structure and the brush plate, thereby improving its performance and service life and having high practical value.

[0044] Example 2

[0045] This embodiment provides a layered high-density fiberboard with an anti-deformation function. Based on Embodiment 1, the design of the moisture removal system is further optimized.

[0046] like Figures 1 to 12 As shown, a hygroscopic layer 9 is fixedly connected to one end of the transverse border strip 1 and the longitudinal border strip 2 close to the layered high-density fiberboard body, and a unidirectional guide layer 10, a siphon layer 11, an inner heat-insulating layer 12, a heat-collecting layer 13 and an outer heat-insulating layer 14 are fixedly connected in sequence to one end of the hygroscopic layer 9 away from the layered high-density fiberboard body. An evaporation layer 15 is fixedly connected to the top of the heat-collecting layer 13, and an end of the siphon layer 11 away from the one-way guide layer 10 is fixedly connected to the evaporation layer 15, and a top end of the outer heat-insulating layer 14 extends to the top end of the evaporation layer 15 and is fixedly connected to the top end of the evaporation layer 15.

[0047] Among them, the hygroscopic layer 9 is made of materials with excellent hygroscopic properties, such as silica gel, alumina, etc. The hygroscopic layer 9 is tightly attached to the layered high-density fiberboard body, and can continuously and effectively absorb moisture in the fiberboard, playing the role of "the first line of defense".

[0048] The unidirectional guide layer 10 is arranged adjacent to the hygroscopic layer 9. The unidirectional guide layer 10 is made of a special material with anisotropic moisture conductive properties, such as a film with a directionally arranged fiber structure. The moisture conductive direction of the unidirectional guide layer 10 is from the hygroscopic layer 9 to the siphon layer 11, and the moisture absorbed by the hygroscopic layer 9 can be quickly introduced into the siphon layer 11, thereby playing a role of rapid transport.

[0049] The siphon layer 11 is made of a hydrophilic polymer film and has an excellent siphon effect. The siphon layer 11 can quickly siphon the water transported from the unidirectional guide layer 10 to the evaporation layer 15 , thereby achieving directional transmission of water in the siphon layer 11 .

[0050] An inner heat-insulating layer 12 is provided between the siphon layer 11 and the heat-collecting layer 13. The inner heat-insulating layer 12 is made of a material with excellent heat-insulating properties, such as an aluminum silicate aerogel board. The inner heat-insulating layer 12 can effectively block the heat transfer from the siphon layer 11 to the heat-collecting layer 13, and use the heat collected by the heat-collecting layer 13 as much as possible for the evaporation process of the evaporation layer 15, thereby improving the dehumidification efficiency.

[0051] The heat collecting layer 13 is a hollow structure, with a porous metal layer fixedly connected to its inner wall, and one-third of the space in the hollow part is filled with liquid ammonia. The heat collecting layer 13 is made of a copper alloy with high thermal conductivity and can effectively absorb ambient heat. When the ambient temperature rises, the liquid ammonia in the heat collecting layer 13 will absorb heat and evaporate, and quickly transfer the heat to the evaporation layer 15, accelerating the evaporation of water absorbed in the hygroscopic layer 9.

[0052] The evaporation layer 15 is made of porous ceramics and has excellent moisture conduction and evaporation properties. A through hole is provided on the evaporation layer 15 to facilitate the timely discharge of water vapor. One end of the evaporation layer 15 is connected to the siphon layer 11, and the other end is connected to the outside atmosphere. Under the dual effects of heating by the heat collection layer 13 and water transport by the siphon layer 11, the evaporation layer 15 can achieve efficient evaporation and discharge of water.

[0053] An external heat-insulating layer 14 is provided outside the heat-collecting layer 13 and the evaporating layer 15. The external heat-insulating layer 14 is similar to the internal heat-insulating layer 12 and is also made of a material with excellent heat-insulating properties. The external heat-insulating layer 14 mainly serves to isolate the external cold air and minimize the heat loss of the heat-collecting layer 13 and the evaporating layer 15.

[0054] When the layered high-density fiberboard absorbs moisture, the moisture is firstly absorbed by the moisture-absorbing layer 9 .

[0055] The wick layer 11 transports the water to the evaporation layer 15 by means of capillary force.

[0056] The heat collecting layer 13 continuously absorbs ambient heat and transfers it to the evaporation layer 15 to accelerate the evaporation of water.

[0057] The evaporation layer 15 evaporates water under high temperature conditions, and the water vapor is discharged into the outside atmosphere through the through holes.

[0058] The inner heat insulation layer 12 and the outer heat insulation layer 14 minimize the heat loss of the heat collection layer 13 and the evaporation layer 15, thereby ensuring the moisture removal efficiency.

[0059] Compared with Example 1, the beneficial effects of this embodiment are mainly reflected in: The dehumidification system is systematically designed, including moisture absorption, moisture conduction, heating, evaporation and other links, with high dehumidification efficiency.

[0060] The provision of the moisture absorption layer 9, the one-way guide layer 10 and the siphon layer 11 ensures efficient and directional transport of water, creating good conditions for subsequent evaporation.

[0061] The heat collecting layer 13 cleverly utilizes the ambient heat to provide energy for evaporation, thus avoiding extra energy consumption and complying with the concept of energy conservation and environmental protection.

[0062] The provision of the inner heat-insulating layer 12 and the outer heat-insulating layer 14 minimizes heat loss and ensures efficient use of the heat collected by the heat-collecting layer 13 .

[0063] The porous ceramic evaporation layer 15 has excellent moisture conductivity and evaporation properties, and the through holes are provided to facilitate the timely discharge of water vapor, further improving the moisture removal efficiency.

[0064] By draining the moisture out of the layered high-density fiberboard, the layered high-density fiberboard is not easily deformed due to humidity changes.

[0065] In summary, based on Example 1, this embodiment optimizes the dehumidification system in terms of material selection, structural design, thermal energy utilization, etc., so that it can continuously and efficiently discharge moisture from the layered high-density fiberboard, effectively inhibit the deformation caused by moisture absorption and expansion of the fiberboard, and improve the performance and service life of the fiberboard.

[0066] Example 3

[0067] This embodiment provides a layered high-density fiberboard with an anti-deformation function. On the basis of Embodiment 1 and Embodiment 2, the structural design and protective function of the upper and lower brush plates are further optimized.

[0068] like Figures 1 to 12 As shown, the corresponding positions of the transverse border strip 1 and the upper brush plate 6 and the lower brush plate 7 are provided with sliding grooves that cooperate with the upper brush plate 6 and the lower brush plate 7. The upper brush plate 6 and the lower brush plate 7 are slidably connected with the sliding grooves on the transverse border strip 1. The ends of the upper brush plate 6 and the lower brush plate 7 that are close to each other are provided with coating ports. The upper brush plate 6 and the lower brush plate 7 are provided with paint grooves for accommodating waterproof paint, and the paint grooves are communicated with the coating ports.

[0069] The top and bottom ends of the corner block 3 are fixedly connected with a corner pressure plate 8, a through groove is opened at the position of the corner block 3 corresponding to the evaporation layer 15, and the through groove is connected to the external space at one end away from the evaporation layer 15, the dovetail tenon 4 is fixedly connected to the corresponding transverse frame strip 1 and the longitudinal frame strip 2 by multiple bolts, and the corner pressure plate 8 is fixedly connected to the corner block 3 by bolts.

[0070] A slide groove cooperating with the upper brush plate 6 and the lower brush plate 7 is provided on the transverse border strip 1, so that the brush plate can slide flexibly in the length direction of the transverse border strip 1, adjust the degree of fit with the surface of the layered high-density fiberboard, and then adjust the pre-tightening force on the fiberboard to achieve active anti-deformation.

[0071] A coating port is provided at one end of the upper brush plate 6 and the lower brush plate 7 which are close to each other, and a paint groove is provided inside the brush plate, which is connected to the coating port. In this way, when the waterproof coating on the surface of the fiberboard is damaged, the waterproof coating can be applied to the surface of the fiberboard through the coating port to repair the waterproof coating and extend the service life of the fiberboard.

[0072] Corner pressure plates 8 are fixedly connected to the top and bottom ends of the corner blocks 3. The corner pressure plates 8 can further enhance the connection strength and stability at the corners, improve the overall rigidity of the frame structure, and better restrain the deformation of the fiberboard.

[0073] A through groove is provided on the corner block 3 at a position corresponding to the evaporation layer 15, and the end of the through groove away from the evaporation layer 15 is connected to the outside air. In this way, the water vapor evaporated from the evaporation layer 15 can be discharged through the through groove, reducing the accumulation of water vapor between the evaporation layer 15 and the corner block 3, ensuring smooth dehumidification.

[0074] The dovetail tenon 4 and the corner pressure plate 8 are detachably connected to the transverse frame strip 1, the longitudinal frame strip 2 and the corner block 3 respectively by bolts. This connection method is convenient for the assembly and disassembly of the frame structure, and through the bolt connection, the tightness of the frame structure can be adjusted as needed to make the frame fit better with the fiberboard.

[0075] The transverse frame strip 1, the longitudinal frame strip 2 and the corner block 3 are connected by dovetail joints 4 and fastened with bolts to form a frame structure.

[0076] Install the upper brush plate 6 and the lower brush plate 7 into the slide groove of the transverse frame strip 1, and adjust the position of the brush plate so that it and the fiberboard surface are evenly stressed.

[0077] The paint grooves of the upward brush plate 6 and the lower brush plate 7 are filled with waterproof paint.

[0078] If the waterproof coating on the fiberboard surface is damaged, it can be repaired by applying waterproof coating through the board coating opening.

[0079] When the fiberboard tends to deform due to moisture, the frame structure and brush plate physically restrain it and apply pre-tightening force by adjusting the position of the brush plate to suppress deformation.

[0080] The moisture absorption layer 9 absorbs the moisture in the fiberboard, and the unidirectional flow guide layer 10 guides the moisture into the wick layer 11, and the moisture is transported to the evaporation layer 15 through the wick layer 11 for heating and evaporation.

[0081] The water vapor generated by evaporation is discharged through the through holes on the evaporation layer 15 and the through grooves on the corner block 3 .

[0082] The beneficial effects of this embodiment are mainly reflected in: The brush plate is slidably connected to the frame bar, and the position can be flexibly adjusted to apply appropriate preload force to actively prevent deformation.

[0083] A paint tank is provided inside the brush plate, which can repair the waterproof coating on the fiberboard surface and extend its service life.

[0084] The corner pressure plate 8 on the corner block 3 further enhances the strength and rigidity of the frame structure and improves the anti-deformation effect.

[0085] The corner block 3 is provided with a through groove, which is beneficial to the timely discharge of evaporated water vapor and ensures smooth moisture discharge.

[0086] The dovetail tenon 4 and the corner pressure plate 8 are connected by bolts, which facilitates the assembly and disassembly of the frame and the adjustment of the tightness.

[0087] When in use, multiple transverse border strips 1 and longitudinal border strips 2 are clamped to the outer ends of the layered high-density fiberboard, and then multiple transverse border strips 1 and longitudinal border strips 2 are fixedly connected through multiple corner blocks 3 to reinforce the layered high-density fiberboard to prevent deformation of the layered high-density fiberboard; Then, the upper brush plate 6 and the lower brush plate 7 are slid to evenly apply the waterproof coating to the surface of the layered high-density fiberboard; During use, the moisture absorption layer 9 continuously absorbs moisture in the layered high-density fiberboard, and the unidirectional guide layer 10 guides the moisture from the moisture absorption layer 9 to the siphon layer 11. The siphon layer 11 concentrates and guides the moisture to the evaporation layer 15, and the moisture evaporates in the evaporation layer 15 and enters the air. During use, the liquid ammonia in the heat collection layer 13 absorbs the heat from the surrounding environment through the transverse frame strips 1 and the longitudinal frame strips 2, and concentrates the heat into the evaporation layer 15, accelerating the evaporation of water in the evaporation layer 15; If the waterproof layer on the surface of the layered high-density fiberboard is damaged during use, the waterproof layer can be re-coated by sliding the upper brush plate 6 and the lower brush plate 7. At the same time, the upper brush plate 6 and the lower brush plate 7 are combined with the transverse border strip 1 and the longitudinal border strip 2 to form a protective frame. During use, the positions of the upper brush plate 6 and the lower brush plate 7 can be adjusted according to the force conditions to better prevent the layered high-density fiberboard from deformation.

[0088] To summarize, based on the previous two embodiments, this embodiment further improves the structural design of the brush plate and the corner block. On the one hand, active anti-deformation is achieved through flexible adjustment of the brush plate. On the other hand, the anti-deformation effect and moisture discharge performance of the frame are enhanced through the optimized design of the corner block, thereby further improving the anti-deformation function and usage experience of the present invention.

[0089] In view of current practical needs, the above-mentioned implementation mode adopted in this application is not limited to the scope of protection. Various changes made within the knowledge scope of technical personnel in this field without departing from the concept of this application still fall within the scope of protection of the present invention.
