Embodiment 1

[0053] Embodiment one: adopt 1.5m 3 Birch wood (density 1:1.2) is used as an example to make black walnut colored wood boards.

[0054] a) Slicing 1mm-10mm thick, preferably 2mm thick veneer skin 0.5m 3 , rotary cut 0.1-2mm thick, preferably 1mm thick veneer skin 1.0m 3 , total: 1.5m 3 .

[0055] b) Add water to the pressure vessel, about 1.5m 3 -2m 3 , add water and preheat to about 40°C, put in dyes, among them, red 1.29kg, accounting for 43%, green 1.38kg, accounting for 46%, blue: 0.33kg, accounting for 11%, a total of 3kg dyes.

[0056] c) Put the prepared veneer into a stainless steel box and put it into a pressure vessel, close the tank mouth of the container, check and lock the tank mouth, and humidify to 90%.

[0057]d) Start the vacuum pump and open the valve to carry out vacuum work negative pressure in the container, the pressure is 1Kg-3Kg / cm 2 , preferably 2kg / cm 2 , time 20-30 minutes, preferably 30 minutes, shut down and return to normal pressure.

Embodiment 2

[0069] Embodiment two: adopt 1.5m 3 Birch wood (density 1:1.2) is used as an example to make black walnut colored wood boards.

[0070] a) Rotary cut 1.2mm thick veneer 1.4m 3 .

[0071] b) Add water to the pressurized container, 1.8m 3 -2.3m 3 After adding water, it can be preheated to about 45°C, and put in basic dyes, red 3.36kg, accounting for 48%, green 3.36kg, accounting for 48%, blue 0.28kg, accounting for 40%, a total of 7kg dyes.

[0072] c) Put the prepared veneer into the stainless steel mesh and put it into the pressure vessel, close the vessel, check and lock the mouth of the tank, and heat to 90°C.

[0073] d) Start the vacuum air pump, and carry out vacuum work in the container negative 2kg / cm 2 , After 30 minutes, stop the machine for back pressure.

[0074] e) Start the vacuum press and pressurize the container to 6kg / cm 2 , After 1 hour, close the valve to stop the machine and discharge the pressure.

[0075] f) Start the vacuum pump, open the valve t...

Abstract

The invention provides a method for manufacturing colored solid wood, aiming at overcoming the defects of natural wood and effectively overcoming the defects that fast growing wood is loose and soft, incapable of resisting corrosion, is easy to burn, and the like. According to the method disclosed by the invention, log is rotationally cut or sliced, then dyed, impregnated with gum and synthesized, so that the natural fast growing wood has abundant colors as well as the characteristics of environment friendliness, flame retardance, moisture resistance, corrosion resistance, wear resistance, low possibility of deformation and strong plasticity.

Description

Technical field: [0001] A method for manufacturing a colored solid wood board proposed by the invention belongs to a wood processing method, and specifically relates to a method for manufacturing a multilayer colored solid wood board. Background technique: [0002] Due to the extensive use of natural wood by humans, the excessive logging of forests has resulted in the destruction of large areas of forests, and some precious tree species are facing the danger of extinction. For this reason, humans have carried out large-scale artificial afforestation, but due to various defects in naturally grown wood, such as scars, dead knots, black lines and other natural defects, and the color difference of the naturally grown edge core material, it is easy to crack, stress, etc. The material defect of changing and bending, and because the fast-growing tree species grows faster, the material itself is too soft, does not have corrosion resistance, flammability and other defects, although a...
