Example Embodiment
[0075] Example 1
[0076] This embodiment is a modified veneer, and its preparation method includes the following steps: immersing the veneer with a thickness of 0.6mm in a treatment solution with a methyl methacrylate concentration of 98%, and the treatment solution contains a mass concentration of 2%. Alcohol penetrant; fully immersed and transferred to a pressurized tank at 1.2kg / m 2 Keep the pressure in an inert atmosphere for 60 minutes, then carry out the polymerization reaction in a reaction tank at 100°C, and then perform an equilibrium treatment at 25°C and a relative humidity of 25% for 7 days to complete the veneer modification.
Example Embodiment
[0077] Example 2
[0078] This embodiment is a modified veneer, and its preparation method includes the following steps: immersing the veneer with a thickness of 0.8mm in a treatment solution with a methyl methacrylate concentration of 97%, and the treatment solution contains a mass concentration of 3% Alcohol penetrant; fully immersed and transferred to a pressurized tank at 1.3kg / m 2 Keep the pressure in an inert atmosphere for 50 minutes, and then carry out the polymerization reaction in a reaction tank at 100°C; then perform an equilibrium treatment at 22°C and a relative humidity of 40% for 6 days to complete the veneer modification.
Example Embodiment
