Problems solved by technology

[0002] At present, the method of wood coloring mainly contains the following two kinds: one is to use colored paint to carry out surface coloring to wood, this method has a wide range of applications, and can carry out various colors of coloring to wood; however, the color of the wood dyed by this method is unnatural , easy to lose color and change color, and has the disadvantages of high cost and complicated operation
The second is to color the surface of the wood after gas fumigation. This method will emit some toxic gases during the operation, and the coloring depth is relatively shallow, and color leakage will occur in the later stage of processing.
[0003] In addition, the above two dyeing methods have unnatural colors and cannot reflect the realistic antique effect of wood.

Embodiment 1

[0023] A dye solution is obtained by the following method:

[0024] ① Putting wood and water injection: put oak wood squares into the oak wood cooking pool, and then inject tap water into the cooking pool, and the tap water can immerse the oak wood squares;

[0025] ② Primary heating: step ① After the water injection is completed, heat the tap water in the cooking pool to 40-45°C and keep it at this temperature for 24 hours;

[0026] ③Steaming: Step ②After the heat preservation is completed, continue to heat the tap water in the cooking pool at a rate of 5°C / h until the temperature is 95-100°C, and cook the oak wood at this temperature for about 22 hours, and the cooking is over Finally, remove the oak timber;

[0027] ④Cyclic treatment: After the oak wood in step ③ is completely removed, put the untreated oak wood into the cooking pool, and the water in the cooking pool can be submerged in the oak wood; at this time, the cooking in the cooking pool When the temperature of t...

Embodiment 2

[0029] A kind of dye liquor, its preparation method is the same as embodiment 1, difference is, in step 4., after the cooking liquor in the cooking tank circulates and processes the oak timber for five times, it is naturally cooled to room temperature, and gets final product after filtering and removing impurities. The dye solution is pumped out into a clean container for later use.

Embodiment 3

[0031] A kind of wood penetrating coloring method, comprises the following steps:

[0032] (1) The dye solution is injected into the iron container, and then the uncolored, shaped maple planks are soaked in the dye solution obtained in Example 1, the dye solution is at least submerged in the wood and ensures that there is enough evaporation in the soaking process The margin does not allow the wood to leak out;

[0033] (2) Heat the iron container containing the dye liquor and wood in step (1), heat it to a temperature of 85-90°C at a rate of 5°C / h, and keep it warm for 5h at this temperature;

[0034] (3) Naturally lower the temperature of the iron container that has been insulated in step (2) to 55° C., and keep it warm for 120 hours at this temperature; pull out the wood from the waste liquid to obtain an antique-made old-fashioned, colored (The dyed wood can be processed into flooring and other furniture after drying). After cutting, it is found that the coloring depth of ...

Abstract

The invention discloses a wood penetration coloring method. Dye liquid is injected in an iron container; then, an uncolored wood is soaked in the dye liquid, and is heated to reach a temperature of 85-95 DEG C at a speed of 5 DEG C / h; and the temperature is kept by 3-5 h; after the insulation is finished, the natural cooling is performed to reach a temperature of 40-60 DEG C, and the temperature is kept by 72-144 h; and the wood is fished out to form the colored wood with an antiquing old effect. The method is suitable for coloring of such woods as maples and oaks; the color of the colored wood is adjusted from light grey to dark grey, and is uniform and natural; the coloring penetration depth can reach 2-4 mm; and the visual effect is older, so that the wood achieves a vivid antiquing old effect. The method is simple in operation, low in cost and free of pollution, uses waste liquid generated in the oak stewing process as the dye liquid, changes wastes into wealth, and kills two birds with one stone.

Description

technical field [0001] The invention relates to a wood treatment process, in particular to a wood penetration coloring method, which belongs to the technical field of wood coloring. Background technique [0002] At present, the method of wood coloring mainly contains the following two kinds: one is to use colored paint to carry out surface coloring to wood, this method has a wide range of applications, and can carry out various colors of coloring to wood; however, the color of the wood dyed by this method is unnatural , easy to lose color and change color, and has the disadvantages of high cost and complicated operation. The 2nd, carry out gas fumigation to its surface layer after wood is carried out coloring, and this method can discharge some poisonous gases in the course of operation, and, the depth of coloring is relatively shallow, can produce the phenomenon of leaking color in the later stage of processing. [0003] In addition, the above two dyeing methods have unnat...
