[0010] A method for preparing carbonized high-strength wear-resistant modified recombined wood flooring, which is produced by the following steps: 1) Using poplar, pine or birch as raw materials, it is peeled into veneers, and the thickness of the veneers is 1.5- 2mm; 2) The veneer is dried and carbonized in a closed environment. The drying and carbonization takes three hours from 0°C to 60°C, five hours from 60°C to 100°C, and five hours from 100°C to 100°C. It takes six hours to reach 150°C, and twelve to fourteen hours to rise from 150°C to 190°C. The moisture content of the veneer after drying and carbonization is below 2%; 3) Use modified phenolic resin glue to dry in step 2 The veneer after dry carbonization treatment is soaked, the soaking time is in the range of 30-35 minutes, the pH value of the glue is 10, the solid content is 40-45%, the free phenol content is less than or equal to 1%, and the free toluene content is less than or equal to 0.1%;4 ) Dry the veneer aft...
Embodiment 1
[0014] Example 1, 1) Using poplar as raw material, it is rotated into veneers, the thickness of which is 1.5mm; 2) The veneers are dried and carbonized in a closed environment, and the drying and carbonization processes are sequentially processed from 0 It takes three hours to rise from ℃ to 60°C, five hours to rise from 60°C to 100°C, six hours to rise from 100°C to 150°C, twelve hours to rise from 150°C to 190°C, and dry and carbonize The moisture content of the final veneer is 1.8%; 3) Use modified phenolic resin glue to soak the veneer after drying and carbonization in step 2 for 32 minutes, the pH value of the glue is 10, and the solid content is 40%. The content of free phenol is 1%, and the content of free toluene is 0.1%; 4) Dry the veneer after step 3, the drying temperature is 100°C, the drying time is 30 minutes, and the moisture content after drying is 2.8%; 5) The veneer produced in step 4 is subjected to moisture regain treatment. The moisture recovery time is 10...
Embodiment 2
[0015] Example 2, 1) Using pine as the raw material, it is cut into veneers with a thickness of 1.8mm; 2) The veneers are dried and carbonized in a closed environment, and the drying and carbonization processes are sequentially processed from 0 It takes three hours to rise from ℃ to 60°C, five hours to rise from 60°C to 100°C, six hours to rise from 100°C to 150°C, and thirteen hours to rise from 150°C to 190°C, drying and carbonization The moisture content of the final veneer is below 1%; 3) Use modified phenolic resin glue to soak the veneer after drying and carbonization in step 2. The soaking time is in the range of 34 minutes. The pH value of the glue is 10 and the solid content is 43. %, free phenol content 0.5%, free toluene content 0.05%; 4) Dry the veneer after step 3, the drying temperature is 100 ℃, the drying time is 20 minutes, and the moisture content after drying is less than or equal to 1.5 %; 5) Re-moisture the veneer from step 4, the re-moisture time is 6 hou...
