Embodiment Construction

[0010] Below in conjunction with embodiment the present invention is described in further detail.

[0011] Material: Ayous veneer;

[0012] Staining solution: FeSO 4 Prepare a solution with a concentration of 10%;

[0013] Fumigation liquid: Na 2 S and H 2 C 2 o 4 Prepare a 10% solution at a ratio of 1:1.

[0014] Fixing solution: prepare chitosan into a solution with a concentration of 0.2%.

[0015] Process: Make the veneer wood to be processed into 100×100×1mm. After drying, immerse the veneer in the above dyeing solution for dyeing. Keep the temperature at 100°C. After cooking for 1 hour, wash it with clean water, and then put it in fumigation Fumigate in the solution for 1 hour, then put it into the color-fixing solution for 15 minutes, and finally wash with water and dry to get a black finished product.

[0016] Metal ion

[0017] At the same time, adjust the concentration of metal ions to obtain stained wood with different degrees of color. Different...

Abstract

A fumigation method for dyeing wood includes such steps as preparing the aqueous solution of sulfate containing any of Fe, Na, Mn and Cu ions as dyeing liquid, boiling the wood in it for 3-4 hr, water washing, fumigating by the aqueous solution of Na2S and H2C2O4 for 1-2 hr, immersing in the aqueous solution of chitosan as colour fixating liquid for 10-20 min, water washing, and baking. Its advantages are deep dyed layer, not decolourant and high optical stability.

Description

technical field [0001] The invention relates to a wood treatment technology, in particular to a wood dyeing process. Background technique [0002] At present, the dyeing of wood is mainly dyed with organic dyes. The method is to immerse the wood in the dyeing solution, so that the dye is immersed in the wood or adsorbed on the surface of the wood to achieve the purpose of dyeing. The main defect of this dyeing method is that the dyed layer is shallow, and the dyed wood is easy to change color and lose color. Contents of the invention [0003] The purpose of the invention is to propose a new wood dyeing method in order to overcome the deficiencies in the prior art. [0004] The technical scheme that the present invention adopts is: at first prepare Fe 2+ 、Na + , Mn 2+ 、Cu 2+ Any kind of sulfate dyeing solution in metal ions, then put the selected wood into a selected metal ion dyeing solution and cook for 3-4 hours at a cooking temperature of 70-100°C, wash with water,...
