Description

DETAILED DESCRIPTION OF THE INVENTION [Technical Field] The present invention relates to an artificial decorative veneer that has a wood grain pattern by subjecting a material veneer made from raw wood to various treatments.

[Background technology]

Conventionally, in order to obtain this type of artificially decorated veneer, the material veneer obtained by cutting logs was dyed to give it color.
Next, a large number of colored veneers of the material were laminated, pressed together to form an artificial flitch, and the artificial flitch was cut using a well-known technique. Decorative boards were created by pasting the board onto a substrate and painting the surface. However, such artificial decorative veneers had the disadvantage that the color tone became monotonous over time. Ta.

[Purpose of the invention]

The present invention aims to eliminate all the drawbacks of the conventional artificially decorated veneers mentioned above, and to widely provide artificially decorated veneers whose color tone becomes more and more vivid over time, thereby contributing to the development of this field. It is.

[Structure of the invention]

The present invention involves rotary cutting or slicing of logs that are unsuitable for use as decorative materials due to unclear grain patterns or monotonous colors, such as Lapra wood, White Seraya wood, Agatis wood, and Teva wood. ] At the same time, the veneer (1) cut into a predetermined size and having a thickness of 0.5% to 3.0% is immersed in a dyeing solution for spring wood color and a dyeing solution for summer wood color, respectively. Create material veneer cutting) and summer wood hue material veneer (3). In addition, at this time, a concentration of 0.05% was added to the dyeing solution for summer wood color.
Silver chloride is added in a weight ratio of 2, and the summer wood hue material veneer (3) is impregnated with silver chloride together with the dyeing solution. Next, the summer wood color material veneer (3) and the spring wood color material veneer (2)
) are laminated alternately as appropriate. At this time, an adhesive such as an area resin adhesive, a phenol resin adhesive, or a urethane resin adhesive is interposed between the adhesives. Next, the laminated summer wood color material veneer (3) and spring material color material veneer (2) are pressed from above and below with a pair of presses (4) (4) to harden the adhesive, The artificial flitches (5) are integrated with each other to form an unevenly shaped artificial flitch (5). Next, the artificial flitch (5) is cut into slices to obtain an artificial decorative veneer (6) having a wood grain pattern.

[Effects of the Invention] The method for producing an artificially decorated veneer of the present invention is configured as described above, and the artificially decorated veneer obtained by the method of the present invention is irradiated with light to transform the summer wood hue material veneer portion. The silver chloride contained in it turns dark (3) 1...Artificially decorated veneer.

By coloring, the summer wood becomes even more dark in color, and has the effect of making the wood grain more vivid as it changes over time.

The artificial decorative veneer obtained by the present invention is a chipboard,
It is pasted onto plywood such as particle board, hardboard, inorganic board, etc. using an adhesive, and the surface is coated with urethane resin paint,
A decorative board may also be created by applying an amino resin paint or the like.

The wood grain pattern of such decorative boards becomes clearer over time (irradiation with light), and is suitable for use as interior materials such as wall materials and floor materials, furniture boards, etc., for example.

Claims (1)

[Claims] l) Each material veneer is dyed to create a summer material emergency material veneer and a spring material coloring material veneer, and the summer material urgent material veneer and spring material coloring material veneer are alternated as appropriate. In the manufacturing method of artificially decorated veneer, which involves laminating and pressing together to form an artificial flitch, and then slicing the artificial flitch, silver chloride is added to the dyeing solution when dyeing the veneer, which is used as a material for summer materials. A method for manufacturing artificially decorated veneer characterized by adding.
