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...

Abstract

The invention discloses a preparation method of a tripolycyanamide veneer cover wood-based panel, wherein the tripolycyanamide veneer mounted wood-based panel comprises a wood-based panel substrate, wherein tripolycyanamide veneer covers are symmetrically adhered on the upper surface and the lower surface of the wood-based panel substrate, and the tripolycyanamide veneer covers are solid wood covers being immersed by tripolycyanamide and having different colors or textures. The preparation method comprises the steps of: immersing the solid wood covers into colorless and transparent tripolycyanamide resin so that tripolycyanamide sizing materials uniformly permeate; then drying the solid wood covers for removing water and evaporating solvent; and heating and pressurizing or pressurizing and laminating by adopting a cold-heat-cold thermal pressing process. Natural wood covers are directly used for replacing printed woodgrained paper, thus solid surface stripes exist on the surface of the panel, formaldehyde pollution in environment is reduced; and the wood covers are not easy to drop, and have high wear-resistant strength and lower cost.

Description

technical field [0001] The invention relates to a preparation method of a wooden board, in particular to a preparation method of a melamine veneered wooden board. Background technique [0002] Large core board (commonly known as blockboard, woodworking board) is a plywood with a solid wood core. The bending strength is poor, but the transverse bending strength is high. The surface material can be divided into three-ply board, five-ply board, etc. according to the number of layers, and can be divided into eucalyptus, beech, teak, etc. according to the tree species. Divide the boards into two types: one-sided gloss and double-sided gloss. The double-sided glossy boards can be used as decorative materials for key parts such as furniture panels, door and window frames, etc. [0003] Multi-layer board, also known as three-plywood and three-ply board, has different names for different layers. Now home decoration mainly uses veneer plywood, that is, a very thin solid wood veneer...
