Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a method for manufacturing a decorative root affixed with a veneer of natural precious wood that emphasizes the grain of the natural precious wood.

Traditionally, decorative veneers made from single roots of natural wood have discolored over time due to wood burn, resulting in an overall darker tone than the original veneer, and the wood grain is not emphasized, so it is colored with a reactive colorant. When treated, there were disadvantages such as the reaction did not proceed uniformly due to unevenness of the wood, there was a lot of color unevenness, and both the spring and autumn wood areas were reactively colored, making it difficult to emphasize the wood grain.

The purpose of the present invention is to solve the above-mentioned drawbacks (secondly, the invention of a method for manufacturing a decorative board made of natural precious wood veneer, which is characterized by being resistant to discoloration and enhancing the value of the decorative board by emphasizing the wood grain). This is related to.

Hereinafter, the present invention will be explained in detail with reference to the drawings showing examples of the present invention.

The surface of a coniferous veneer 2 attached to the upper surface of a base material l such as plywood is subjected to plascing to make the autumn wood part a a convex part and the spring wood part b'
6. An uneven surface with concave portions is formed, and a paint-type sealer 3 colored in the same color as the spring wood portion is applied to the entire surface of the uneven surface and dried, and the surface of the autumn wood portion a, which is the convex portion, is ground. After removing the sealer, a reactive coloring agent 4 is applied to the entire surface to darken only the autumn wood part a.0Next, the effects of the present invention will be explained with reference to practical example diagrams. Explain 0 Coniferous veneer 2 has a clear difference between autumn wood part a and spring wood part A. Autumn wood part A has a higher specific gravity and is denser than spring wood part A, and contains more pigments etc. It will be done. Therefore, when the surface of the single phase 2 is pressed, six autumn wood portions a are provided in a convex shape, and the spring material portions are ground and provided in a concave shape. Therefore, in order to cover the spring wood parts by applying sealer 3 of the same color as the spring wood parts, the reactive coloring agent 4 is applied to the autumn wood parts a which are ground from the sealer agent 3.
Penetrates only into the wood and develops color with the pigment components in the autumn wood part a,
Since the autumn wood part a is clearly exposed and colored, there is no uneven coloring and it is difficult to discolor.Furthermore, the soft spring wood part is recessed and covered with sealer 3, so it is hard to get scratched and the decorative board is It has the above-mentioned remarkable effects such as being able to increase the commercial value.

Claims (1)

[Claims] 1. The upper surface of a base material such as plywood (2) The surface of the attached coniferous veneer is plated to form an uneven surface with the autumn wood part as a convex part and the spring wood part as a concave part, and the uneven surface is Apply a paint-type sealer colored to the same color as the spring wood over the entire surface and let it dry. After removing the sealer by grinding the surface of the convex autumn wood, apply a reactive colorant over the entire surface to prepare the autumn wood. A method for manufacturing a decorative board made of natural precious wood veneer with little discoloration, characterized by darkening only the parts.
