Embodiment 1
[0031] A process for manufacturing decorative wood-based panels, including:
[0032] 1. Prepare the wood-based panel substrate: Step 1. Use 5% urea to soak the wood veneer for 2 days, then dry it to a moisture content of 10%; repeat Step 1 3 times to obtain a dry veneer; Step 2. After the veneer is dried and glued, it is paved and assembled to form a slab; step 3, the slab is hot-pressed to obtain a plywood, and the upper and lower sides of the plywood are sanded to obtain the wood-based panel substrate.
[0033] 2. Lay the decorative sticker on the wood-based panel substrate to obtain the wood-based panel substrate covered with the decorative sticker.
[0034] 3. Lay a 12 mm thick fiberboard on the lower platen of the hot press, set the temperature of the upper platen of the hot press to 130°C, the unit pressure of the hot press to 0.8 MPa, and the hot pressing time to 90 seconds. When the temperature of the fiberboard is the same as that of the pressing plate on the hot pre...
Embodiment 2
[0037] A process for manufacturing decorative wood-based panels, including:
[0038] 1. Prepare the wood-based panel base material: step 1, use 10% urea to soak the wood veneer for 1 day, and then dry it to a moisture content of 10%; repeat step 1 3 times to obtain a dry veneer; step 2, the After the veneer is dried and glued, it is paved and assembled to form a slab; step 3, the slab is hot-pressed to obtain a plywood, and the upper and lower sides of the plywood are sanded to obtain the wood-based panel substrate.
[0039] 2. Lay the decorative sticker on the wood-based panel substrate to obtain the wood-based panel substrate covered with the decorative sticker.
[0040] 3. Lay a 12 mm thick fiberboard on the lower platen of the hot press, set the temperature of the upper platen of the hot press to 150°C, the unit pressure of the hot press to 1.5 MPa, and the hot pressing time to 50 seconds. When the temperature of the fiberboard is the same as that of the pressing plate on...
Embodiment 3
[0043] A process for manufacturing decorative wood-based panels, including:
[0044] 1. Preparation of wood-based panel base material: Step 1. Use 10% urea to soak the wood veneer for 1 day. The wood veneer includes rotary-cut veneer and quarter-cut board, and then dry to a moisture content of 10%; repeat steps 1 and 3 Obtain dried rotary-cut veneer and quarter-sawn board for the first time; step 2, after coating the dried rotary-cut veneer and quarter-sawn board with glue, select the rotary-cut veneer as the middle layer of the slab, and use the quarter-sawn board as the slab The upper and lower surface layers of the plywood are paved and combined to form a slab; step 3, the plywood is obtained by hot pressing the slab, and the upper and lower sides of the plywood are sanded to obtain the wood-based panel substrate.
[0045] 2. Lay the decorative sticker on the wood-based panel substrate to obtain the wood-based panel substrate covered with the decorative sticker.
