Problems solved by technology

[0002] The current veneer veneer technology is still dominated by animal glue and manual bonding. The product veneer has poor moisture resistance, low bonding strength, easy to see through and degumming, and it is difficult to splice the seams tightly. The efficiency is low and cannot meet mass production.

Embodiment 1

[0016] First sand the wood-based panel to remove surface dust;

[0017] Cut two pieces of veneer with a thickness of 0.25 mm and a moisture content of 5 to 20 percent to the same size as the wood-based panel, and prepare two pieces of polyester mesh of the same size. for 120.

[0018] Adhesive preparation, the ratio is 20 parts of urea-formaldehyde glue, 20 parts of vinyl acetate latex, and 0.3 parts of ammonium chloride. Mix and stir them evenly to make an adhesive. Immerse the mesh completely in the glue and soak for 10 minutes;

[0019] Spread the two pieces of mesh and paste them on both sides of the wood-based panel respectively, and then stick the veneer on the mesh. The mesh is between the veneer and the wood-based panel, and then send them together to a hot press for pressing at 120°C , the pressure is 0.5 MPa, and the pressure is released after 5 minutes to make a veneer wood-based panel.

Embodiment 2

[0021] First sand the wood-based panel to remove surface dust;

[0022] Cut two pieces of veneer with a thickness of 0.25 mm and a moisture content of 20 to 50 percent to the same size as the wood-based panel, and prepare two pieces of polyester mesh of the same size. The number is 100.

[0023] Adhesive preparation, the ratio is 30 parts of urea-formaldehyde glue, 30 parts of vinyl acetate latex, and 0.3 parts of ammonium chloride. Mix them evenly to make an adhesive. Immerse the mesh completely in the glue and soak for 10 minutes;

[0024] Spread the two pieces of mesh and paste them on both sides of the wood-based panel respectively, and then stick the veneer on the mesh. The mesh is between the veneer and the wood-based panel, and then send them together to a hot press for pressing at a temperature of 150°C , the pressure is 0.4MPa, and the pressure is released after 5 minutes to make a veneer wood-based panel.

Abstract

The invention provides a manufacturing method of a veneered artificial board. The manufacturing method comprises the following steps: sanding, namely sanding two sides of an artificial board; materialpreparation, namely preparing two pieces of veneers and two pieces of mesh cloth, wherein shapes of the veneers and the mesh cloth are consistent with the board surface shape of the artificial board;sizing, namely completely immersing the mesh cloth in glue; board lamination, namely spreading the two pieces of mesh cloth, adhering the two pieces of mesh cloth to two surfaces of the artificial board respectively, and adhering the veneers to the mesh cloth, wherein the mesh cloth is positioned between the veneers and the artificial board; and hot pressing, namely putting the laminated artificial board into a hot press for pressing under the pressure of 0.4-0.5MPa, pressurizing for 5 minutes, and then relieving the pressure to prepare the veneered artificial board.

Description

technical field [0001] The invention relates to the veneer veneer technology of wood-based panels. Background technique [0002] The current veneer veneer technology is still dominated by animal glue and manual bonding. The product laminate has poor moisture resistance, low bonding strength, easy to see through and degumming, and it is difficult to splice the seams tightly. The efficiency is low and cannot meet mass production. Contents of the invention [0003] In view of the problems referred to above, the invention provides a kind of veneer wood-based panel manufacturing method, comprising steps: [0004] Sanding, sanding both sides of the wood-based panel; [0005] Material preparation, prepare two pieces of veneer and two pieces of mesh, the veneer and mesh are consistent with the shape of the wood-based panel; [0006] For sizing, completely immerse the mesh in the glue; [0007] Stack the boards, spread out the two pieces of mesh and stick them on both sides of t...
