Abstract
Description
Technical Field
[0001] This invention relates to the field of engineered wood products technology, and more specifically to a heat-insulating and sound-absorbing engineered wood product and its preparation method. Background Technology
[0002] Engineered wood products (AWD) are boards or molded products made from wood or other non-wood plant materials. These materials are mechanically processed into various single-crystal materials and then bonded together with or without adhesives and other additives. They mainly include three categories: plywood, particleboard, and fiberboard, with hundreds of related and processed products. The advent of engineered wood products marked the beginning of the modern era of wood processing, transforming the process from simply changing the shape of wood to improving its properties. This development involved not only all wood processing techniques but also the absorption of technologies from textiles, papermaking, and other fields, thus forming independent processing technologies. Furthermore, engineered wood products can improve the overall utilization rate of wood; one cubic meter of engineered wood product can replace three to five cubic meters of logs.
[0003] Compared with sawn timber, the advantages of engineered wood products are: larger size, better structure, and easier construction; lower expansion and shrinkage rate, more stable dimensions, more uniform material, and less prone to deformation and cracking; the veneer and various scraps used as raw materials for engineered wood products are easy to impregnate, thus allowing for various functional treatments (such as flame retardancy, corrosion resistance, shrinkage resistance, and wear resistance); a wider range of thickness and density grades with strong applicability; and better bending and forming performance than sawn timber. There are some problems with the use of existing engineered wood panels, as follows: Because existing engineered wood panels are formed by crushing and pressing fiber structures, they have poor heat and sound insulation properties, leading to many unsuitable applications. Summary of the Invention
[0004] In order to overcome the above-mentioned defects of the prior art, the present invention provides a heat-insulating and sound-absorbing artificial board and its preparation method, so as to solve the problems existing in the background art.
[0005] The present invention provides the following technical solution: a heat-insulating and sound-absorbing artificial board, comprising an artificial board body, an inlay assembly fixedly connected to the top of the artificial board body, an artificial board sealing strip fixedly connected to both the front and back of the artificial board body, a first connecting assembly fixedly connected to one side of the artificial board body, and a second connecting assembly fixedly connected to the other side of the artificial board body.
[0006] Furthermore, the top and bottom of the artificial board body are provided with square grooves of the same width as the artificial board body, and the depth and width of the square grooves at the top and bottom of the artificial board body are matched with the length of the inlay component.
[0007] Furthermore, the area of the front side of the artificial board body matches the area of the back side of the artificial board sealing strip, and the sum of the width of the artificial board body and the thickness of the two artificial board sealing strips is the same as the length of the first connecting component.
[0008] Furthermore, the inlay assembly includes a silicone inlay strip, the bottom of which has three sound-insulating grooves. The spacing between the top inlay assemblies of the artificial board body is the same as the spacing between the bottom inlay assemblies of the artificial board body. The spacing between two adjacent top and bottom inlay assemblies of the artificial board body is half the spacing between the two top inlay assemblies of the artificial board body.
[0009] Furthermore, the bottom of the second connecting component matches the top of the first connecting component, the width of the first connecting component matches the width of the second connecting component, and the sum of the thickness of one side of the first connecting component and the thickness of one side of the second connecting component is the same as the thickness of the main body of the artificial board.
[0010] A method for preparing a heat-insulating and sound-absorbing engineered wood panel, characterized by comprising the following steps: S1. Select one part pine wood, one part poplar wood, five parts wheat straw, three parts hemp straw, and five parts bamboo poles, chop and crush them, and mix them evenly to obtain mixture one. S2. Dry the mixture to control its moisture content between 3% and 5%. S3. Add five parts of adhesive, two parts of waterproofing agent and one part of preservative to the dried mixture one, and stir evenly to obtain mixture two. S4. Place the mixture into a mold and pressurize and dry it to form a wood-based panel, with a final moisture content between 7% and 10%. S5. Cut the processed artificial board into wood pieces that are 5 mm thicker and 1 cm wider than the main body of the artificial board to obtain wood piece number one. Then, according to the length of the main body of the artificial board, divide wood piece number one into wood pieces that are 1 cm longer than the main body of the artificial board to obtain wood piece number two. S6. Sand all six sides of the No. 2 wood with a sander. Sand the four sides of the No. 2 wood with sandpaper of 200 grit, 400 grit, 800 grit, 1000 grit and 2000 grit respectively. The total thickness of each side is 5.5 mm. Then, sand the top and bottom sides of the processed wood with sandpaper of the same grit and the thickness is 3 mm. Then the No. 3 wood is obtained. S7. Using a grooving machine, inlay grooves that match the width and depth of the inlay components are cut into the top and bottom of the No. 3 wood, and the inside of the inlay grooves is polished to remove the burrs inside the inlay grooves to obtain the No. 4 wood. S8. A silicone part with the same shape as the inlay component is molded out by silicone molding. Then the inlay component is inlaid into the inlay grooves opened at the top and bottom of the artificial board body in sequence to obtain the first assembly. S9. The second assembly is obtained by processing wood into the shape of a wood-based panel sealing strip, a first connecting component, and a second connecting component, and then connecting the wood-based panel sealing strip, the first connecting component, and the second connecting component to the periphery of the wood-based panel body using adhesive. S10. Then, paint the perimeter of the second assembly to obtain the finished artificial board.
[0011] The technical effects and advantages of this invention are as follows: This invention, through the artificial board body, inlay components, and artificial board sealing strip, facilitates the reduction of noise and heat as they pass through the silicone inlay strip and sound insulation groove during the contact process with the artificial board. The noise is effectively reduced by the gas passing through the sound insulation groove, and the heat is effectively insulated due to the material of the silicone inlay strip.
[0012] The present invention, by providing a first connecting component and a second connecting component, facilitates the rapid assembly of artificial boards during the installation process, saving the workload of installers and reducing on-site construction time. Attached Figure Description
