Problems solved by technology

[0002] The color and texture of wood products affect its value. The purpose of wood coloring is to improve the decorative and aesthetic value of wood products, to achieve the desired color, and to meet people's pursuit of natural beauty. At present, wood coloring mainly uses colored coatings on the wood surface For coloring, colored paints are mostly chemical components, and toxic gases are likely to be generated after painting, and the coating is not in sufficient contact with the wood, and it is prone to peeling off for a long time

Embodiment 1

[0018] Embodiment 1: a kind of method that adopts natural coloring agent to carry out antique coloring to wood chips, processing steps are as follows:

[0019] (1) During the fermentation stage of black tea at room temperature, every 16 days, evenly spray a layer of ferrous sulfate 600 times liquid on the surface of the black tea, and after continuous fermentation for 10 months, bake the black tea until the water content is 10%;

[0020] (2) Mix the roasted black tea with water at a volume ratio of 1:5, boil it, let it stand at 4°C for 12 hours, filter out the tea dregs, concentrate the tea juice to 1 / 2 of the original volume, and obtain concentrated tea juice;

[0021] (3) Soak wood chips in 500 times sodium silicate aqueous solution for 7 hours, and dry them under hot air at 35°C until the water content in the center is 16%;

[0022] (4) Immerse the wood chips in the concentrated tea juice, and treat them intermittently under electromagnetic waves with a frequency of 180MHz...

Abstract

The invention relates to the technical field of wood treatment, in particular to a method for antique coloring of wood chips using natural colorants, specifically, during the fermentation stage of black tea at room temperature, a layer of ferrous sulfate 600-700 times liquid is evenly sprayed on the surface of black tea at intervals , the obtained black tea is mixed with water, boiled, left standing at low temperature, concentrated, soaking wood chips in 500 times sodium silicate aqueous solution for 7-8 hours, drying under hot air, immersing wood chips in concentrated tea juice, Intermittent treatment under electromagnetic waves, the wood chips are taken out and dried under hot air at 35-39°C until the water content in the center is 16-18%. Pollution does not produce toxic gases and other advantages, and the final antique and old-fashioned effect is highly realistic.
