Description

[Detailed Description of the Invention] [Technical Field] This invention belongs to the technical field of processing a material veneer to create an artificial decorative veneer with a wood grain pattern, surface reinforcement, and unevenness.

[Background technology]

Conventionally, as a means of forming irregularities on the surface of a veneer, a known and publicly used technique has been to apply a brushing process to polish the soft parts. However, due to its length, it was necessary to use a veneer of considerable thickness, and a process of polyester coating was also necessary as a means of surface treatment.

[Purpose of the invention]

The present invention aims to contribute to the development of this field by broadly providing a method for manufacturing artificially decorated veneers that uses thin flakes to create irregularities on the surface and at the same time strengthens the surface. be.

[Structure of the invention]

Hereinafter, the method for manufacturing the artificially decorated veneer of the present invention will be explained in detail based on the embodiments shown in FIGS. 1 to 5.

The present invention involves cutting logs such as Agatis wood, Aius wood, Labra wood, Tepa wood, etc. into a predetermined size using rotary cutting or slicing. A board (1) is created. Next, a part of the veneer board (1) is immersed in a polyester solution (2) to create a veneer αυ of the resin-impregnated material. Next, the veneer board aυ of the resin-impregnated material and a veneer of material that is not impregnated with resin (1
) and adhesives such as urea resin adhesive, phenolic resin adhesive, urethane resin adhesive, etc.
Stack them alternately as appropriate and press a pair of presses from above and below (3)
(3) to form an artificial flitch (4) with an uneven shape, and cut the artificial flitch (4) into a thin piece (5) with a thickness of 0.2% to 0.5%. ), cover the thin piece (5) with polyester resin sheet I-(6), and press the flat plate (7) (7) from above and below.
) is an artificial decorative veneer (8) obtained by heat pressing.

As shown in FIGS. 6 and 7, a thin piece (5) is placed on a substrate (9) such as plywood, particle board, hardboard, chipboard, etc. with an adhesive interposed therebetween, and a polyester resin By covering the sheet (6) and pressing under heat, an artificial decorative veneer-attached decorative board (10) can be instantly created.

Figures 8 and 9 show the technical content related to the present invention, in which a paint containing naphthene cobalt and other polyester resin curing agents is applied to the surface of the flakes (5) produced in the manufacturing process of the present invention. After applying, sanding is performed. At this time, the paint (b) on the resin-impregnated cable veneer portion Q+) is removed, and the paint on the material veneer portion αQ is not removed because it is impregnated inside. Next, when a polyester resin paint (60) is applied on the thin piece (5), the polyester resin paint (60) of the material veneer portion 01) containing a hardening agent is applied.
The polyester resin paint (60) on the resin-impregnated material veneer portion (111) is cured and removed by simple sanding to form an artificial decorative veneer (111) having an uneven shape.
80) can be obtained.

〔Effect of the invention〕

The present invention is constructed as described above, and according to the manufacturing method of the present invention, it is possible to very easily strengthen the surface and perform uneven processing. In particular, it has the effect of making it possible to perform uneven processing even on extremely thin thin pieces.
