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

Abstract

The invention relates to the technical field of wood treatment, in particular to an archaized coloring method for wood chips through a natural colorant. Specifically, the method comprises the steps that at a black tea room temperature fermentation stage, a layer of 600-700-fold ferrous sulfate is evenly sprayed on the surface of black tea in a mist mode at intervals, and after the obtained black tea is evenly mixed with water, boiling, low-temperature still standing and concentration are sequentially conducted; and the wood chips are steeped in a 500-fold sodium silicate water solution for 7-8 hours and are dried under hot air, the wood chips are steeped in concentrated tea liquor and are treated under electromagnetic waves at intervals, and the wood chips are taken out and dried under the hot air of 35-39 DEG C till the central water content is 16-18%. According to the archaized coloring method for the wood chips through the natural colorant, antiquing coloring is conducted on the wood chips through the concentrated black tea liquor, therefore the method has the advantages that the coloring effect is good, the cost is low, pollution does not exist, and poisonous gas cannot be generated, and the fidelity of the finally-presented antiquing antique finish effect is high.
