Description

Technical Field

[0001] The utility model relates to the technical field of artificial wood boards, in particular to a separated moisture-proof artificial board. Background Art

[0002] Artificial boards are made by gluing wood chip particles with an adhesive and hot-pressing them into shape, and include a core board composed of larger wood chip particles, and an upper surface layer and a lower surface layer composed of smaller wood chip particles.

[0003] Because the particles inside the core board are large and the particles are hard, they can be made into relatively complete boards. The wood particles are long strips of about 5 cm. Therefore, after being pressed into boards, due to their large particles, there are obvious gaps between the internal wood strips, which are relatively loose; while the particles of the upper and lower surfaces are small in size, generally 2-3 mm, and the wood particles inside are dense, which are relatively flat and small particle flat plates after compaction. Artificial boards use the core board as the main supporting structure, and the surface layer as a scratch-proof and moisture-proof cover to cover and protect the core board.

[0004] In the actual application of artificial boards, their moisture-proof performance is very important. If moisture enters the gaps of artificial boards, especially the gaps in the core board, the wood strips that make up the core board will become damp, and the wood strips will become soft after getting damp, causing the overall strength of the board to decrease. Because the gaps between the wood particles on the surface and inside the core board are different in size, the degree of moisture is also different. When the degree of moisture is different, the amount of wood shrinkage and expansion is different, which may cause the layer structure of the board to peel off, making the board unusable.

[0005] In the existing moisture-proof artificial board technology, the core board is prevented from getting damp and mildewed by injecting glue or adding a covering layer between the core board and the upper surface layer, or between the core board and the lower surface layer.

[0006] However, when the board is actually used, water will not enter the surface, and both the upper and lower surfaces have a good moisture-proof effect. However, the core board in the middle layer has a loose structure, and external moisture and water can enter from the sides of the joints. Due to the different densities between the upper and lower surfaces and the core board, there will be an obvious construction joint. This construction joint will become a space for humid air to store and a channel for invading the core board, which will cause moisture and water to easily diffuse along the side of the board to the inside of the core board, thereby causing the entire board to become damp.

[0007] Based on this, the utility model designs a partitioned moisture-proof artificial board to solve the above problems. Utility Model Content

[0008] The utility model aims to provide a partitioned moisture-proof artificial board, by adding a fiber mesh layer between the core board and the upper surface layer, so that the surface structure of the core board is more complete and not easy to crack, and at the same time, water-resistant and mildew-proof oxidized starch glue is filled in the gaps between the upper and lower surface layers, and the core board is wrapped, so as to effectively prevent moisture from penetrating into the core layer, reduce the strength reduction and delamination problems of the board due to moisture absorption, and significantly improve the moisture-proof performance of the artificial board; the present invention adopts a plurality of positioning groove structures to separate the core board area, effectively put an end to the looseness inside the core board, and the structure of the continuous gap, so that even if the board of the device is locally affected by moisture, it is not easy to spread to the entire artificial board to be damaged by moisture.

[0009] The utility model is implemented as follows: a partitioned moisture-proof artificial board, comprising:

[0010] Lower surface layer, upper surface layer, positioning mesh plate, fiber mesh and core plate;

[0011] The lower surface layer and the upper surface layer are both closed flat plates;

[0012] The positioning mesh plate is a flat mesh frame structure, the bottom of the positioning mesh plate is a flat mesh plate, a plurality of positioning grooves are opened downward from the top of the positioning mesh plate, the plurality of positioning grooves are evenly distributed in a rectangular array, a partition frame is set between each of the positioning grooves, each of the positioning grooves is isolated from each other by the partition frame, and the top of each positioning groove is open;

[0013] The core plate is a flat plate structure, and a core plate is placed in each positioning groove;

[0014] The fiber net is a flexible mesh cloth, the fiber net covers the top of the core plate, and the core plate is sandwiched between the positioning mesh plate and the fiber net;

[0015] The top of the fiber mesh is covered with an upper surface layer, the space between the lower surface layer and the upper surface layer is filled with isolation glue, the gaps between the positioning mesh plate, the core plate and the fiber mesh are filled with isolation glue, and the outside of each core plate is coated with isolation glue;

[0016] The top of the upper surface layer is also covered with a waterproof protective layer (12.

[0017] Further, the top of the core plate protrudes above the bulkhead;

[0018] The core board, the lower surface layer and the upper surface layer are all hard wood particle boards, and the internal constituent particles of the core board are larger than the internal wood particles of the lower surface layer and the upper surface layer.

[0019] Furthermore, the size and depth of each positioning groove are the same, and the positioning mesh plate is closed at the bottom opening of the positioning groove;

[0020] The positioning mesh plate and the partition frame are an integral structure made of plastic.

[0021] Furthermore, the fiber web is also immersed in the isolation glue;

[0022] The isolation glue is oxidized starch glue.

[0023] Furthermore, the waterproof protective layer is a polyvinylidene chloride film with a thickness of not less than 1 mm.

[0024] The beneficial effects of the utility model are as follows: 1. The utility model adds a positioning mesh plate to separate the core board, so that the original whole core board is isolated into multiple independent structures, so that the gaps between each core board are not connected, and the internal gaps of the loose structure of the core board are effectively prevented from connecting the entire board. Such a structure effectively prevents moist air from spreading unimpeded in the entire core board layer, effectively isolates air circulation, and thus avoids the whole core board from being damp;

At the same time, a positioning mesh is also set at the bottom. The positioning mesh can make the bottom of the core board have better integrity, so that the core board is protected by the positioning mesh and the bottom is not easy to crack;

[0026] 3. Isolation glue is injected between the upper surface and the lower surface, which can glue the positioning mesh, core board and fiber mesh into an integral flat structure, so that the core board is protected by the isolation glue as a whole, greatly reducing the possibility of the core board being affected by moisture, even the side will not be affected by moisture.

[0033] See also Figures 1 to 3As shown, the utility model provides a partitioned moisture-proof artificial board. In order to better understand the above technical solution, the above technical solution will be described in detail below in conjunction with the accompanying drawings in the specification and specific implementation methods.

[0034] In a specific embodiment of the technical solution of the utility model:

[0035] It includes a lower surface layer 1, an upper surface layer 11, a positioning mesh plate 2, a fiber mesh 3 and a core plate 4; the lower surface layer 1, the positioning mesh plate 2, the core plate 4, the fiber mesh 3 and the upper surface layer 11 are stacked in sequence from bottom to top;

[0036] The lower surface layer 1 and the upper surface layer 11 are both closed flat plates;

[0037] The positioning mesh plate 2 is a flat mesh frame structure, the bottom of the positioning mesh plate 2 is a flat mesh plate, and a plurality of positioning grooves 22 are opened downward from the top of the positioning mesh plate 2, and the plurality of positioning grooves 22 are evenly distributed in a rectangular array, and a partition frame 21 is arranged between each positioning groove 22, and each positioning groove 22 is isolated from each other by the partition frame 21, and each positioning groove 22 is open at the top; the size and depth of each positioning groove 22 are the same, and the positioning mesh plate 2 is closed at the bottom opening of the positioning groove 22; the positioning mesh plate 2 and the partition frame 21 are an integral structure made of plastic, and the structural integrity is stronger, so that the overall structural strength of the plate is better.

[0038] The core plate 4 is a flat plate structure, and a core plate 4 is placed in each positioning groove 22; the top of the core plate 4 protrudes above the partition frame 21, that is, the top of the core plate 4 should be higher than the top of the partition frame 21, and the difference is not less than 5mm, so as to ensure that the fiber mesh 3 can be laid flat and covered on the top plane of the core plate 4;

[0039] The core board 4 , the lower surface layer 1 and the upper surface layer 11 are all hard wood particle boards, and the internal constituent particles of the core board 4 are larger than the internal wood particles of the lower surface layer 1 and the upper surface layer 11 .

[0040] The fiber net 3 is a flexible mesh cloth, which covers the top of the core board 4, and the core board 4 is sandwiched between the positioning mesh board 2 and the fiber net 3; the fiber net 3 is also immersed in the isolation glue 31; the isolation glue 31 is oxidized starch glue, which is effectively waterproof.

[0041] The top of the fiber mesh 3 is covered with an upper surface layer 11, the space between the lower surface layer 1 and the upper surface layer 11 is filled with isolation glue 31, the gaps between the positioning mesh plate 2, the core plate 4 and the fiber mesh 3 are filled with isolation glue 31, and the outside of each core plate 4 is covered with isolation glue 31;

[0042] The top of the upper surface layer 11 is also covered with a waterproof protective layer 12, which is a polyvinylidene chloride film with a thickness of not less than 1 mm.

[0043] After the production is completed, during actual installation and use, the side walls of the board need to be wrapped with edge banding strips to improve the sealing of the side edges of the board, which not only reduces the aging speed of the isolation glue 31 inside the board, but also effectively prevents external water vapor from entering the core board 4.

[0044] It should be noted that: in any layer structure covering process of artificial board, there must be a construction joint between different layers. This gap is a gap of a whole layer. Generally, this gap needs to be glued to glue the different layers into a whole. However, the gluing is generally done by gluing at continuous intervals between the upper and lower layers. There is also a more rigorous gluing method, which is to glue in parallel lines to form a stronger bonding effect. However, with this gluing method, there will still be a construction joint between the upper and lower layers, and air will be retained and continuously absorbed inside the construction joint. For such a board, humid air in the air continuously enters the core board, and after water vapor enters the core board 4, it is absorbed by the wood and is difficult to separate. In this case, the impact is not significant in the short term. After a long time, the entire core board layer will be very humid, which will cause the board to crack, delaminate, soften and other adverse effects. The present device separates the core board into multiple independent The flat plate is partitioned and placed on the lower surface layer 1, and is isolated and divided by the positioning mesh plate 2, and at the same time isolated by the partition frame 21, so that the overall force of the plate is evenly distributed without affecting the overall strength, and a fiber mesh 3 is added on the top of the core plate 4. The fiber mesh 3 itself has the effect of preventing the surface from cracking. Generally speaking, the fiber mesh 3 is used more in the construction industry. The fiber mesh 3 is attached to the wall surface, which can make the wall surface have higher toughness and wear resistance, and also improve the anti-seepage, anti-breakage and impact resistance. The device attaches the fiber mesh 3 to the top of the core plate 4 and injects isolation glue 31, so that the isolation glue 31 is solidified to form a similar reinforced structural layer, which also has higher structural performance, effectively preventing the core plate 4 from deformation, and at the same time, all the core plates 4 can be wrapped and protected by the isolation glue 31, effectively avoiding the core plate 4 from contacting with the air, improving the moisture-proof performance of the plate, and strengthening the overall structural strength of the plate.

[0045] When the utility model is manufactured, the positioning mesh plate 2 is firstly glued to the top of the lower surface layer 1, so that the bottom of the positioning mesh plate 2 has better sealing performance, and at the same time the positioning mesh plate 2 and the lower surface layer 1 are firmly bonded.

[0046] Before placing the core board 4, it is necessary to inject isolation glue 31 on the top of the positioning mesh board 2, and then place the core board 4 in the positioning groove 22 on the positioning mesh board 2, so that the isolation glue 31 completely covers the bottom of the core board 4. After the core board 4 is placed, fill the isolation glue 31 between the gap between the core board 4 and the positioning mesh board 2, so that the isolation glue 31 covers the gap and the surface of the core board 4, and the oxidized starch glue forms an isolation glue 31 layer structure, and then lay the fiber mesh 3, and then lay the isolation glue 31 again, so that the isolation glue 31 and the fiber mesh 3 are fused into a mixed layer, and then lay the upper surface layer 11 on the fiber mesh 3, and process the polyvinylidene chloride layer on the upper surface layer 11 to form a waterproof protective layer 12. The waterproof effect of the upper surface layer 11 is achieved through the waterproof protective layer 12, the toughness and connection strength are enhanced by the fiber mesh 3, and the isolation glue 31 plays a waterproof role for the core board 4. Since the core board 4 is a plurality of block structures, even if the outermost core board 4 is damp, and the core board 4 is separated by the positioning mesh board 2, the humid water vapor is isolated by the partition frame 21 to prevent the humid air from diffusing to all the core boards 4 of the artificial board, thereby reducing the impact of moisture on the overall artificial board.

[0047] Although the specific implementation methods of the present invention are described above, those skilled in the art should understand that the specific embodiments described are only illustrative and are not intended to limit the scope of the present invention. Equivalent modifications and changes made by those skilled in the art in accordance with the spirit of the present invention should be included in the scope of protection of the claims of the present invention.
