Embodiment 1
[0023] Such as figure 1 As shown, the melamine veneer paste large core board of the present embodiment comprises a large core board substrate 1, and the upper and lower surfaces of the large core board substrate 1 are symmetrically bonded with melamine veneer pastes 2, 3, and the melamine veneer Stickers 2 and 3 refer to solid wood veneers with different colors or textures impregnated with melamine. The preparation method of the large core board includes the following steps:
[0024] The solid wood veneer is impregnated into the colorless and transparent melamine resin, and the melamine glue is evenly penetrated into the solid wood veneer by impregnation;
[0025] Then dry the solid wood veneer, remove moisture and solvent volatilization, seal the solid wood veneer with a plastic film and store it in a constant temperature and humidity environment, the temperature is about 20 degrees Celsius, and the humidity is 50-60%;
[0026] Then heat and press in the hot press, the heati...
Embodiment 2
[0035] The melamine veneer laminated multilayer board of this embodiment comprises a multilayer board substrate, and the upper and lower surfaces of the multilayer board substrate are symmetrically bonded with melamine veneer, and the melamine veneer refers to a tape impregnated with melamine. There are solid wood veneers of different colors or textures, and the method for preparing the multilayer board comprises the following steps:
[0036] The solid wood veneer is impregnated into the colorless and transparent melamine resin, and the melamine glue is evenly penetrated into the solid wood veneer by impregnation;
[0037] Then the solid wood veneer is dried, and the solid wood veneer is sealed with a plastic film and stored in a constant temperature and humidity environment, the temperature is about 20 degrees Celsius, and the humidity is 50-60%;
[0038] Then use the cold-hot-cold hot pressing process in the hot press to press and bond, that is, when the slab enters the pres...
