Description

[Detailed description of the invention] This invention relates to a method for manufacturing decorative veneers.

When the ring-hole material is cut horizontally, as shown in Fig. 1, the spring wood part 1 and the summer wood part 2 form one annual ring, and the conduit of the spring wood part 1 is connected to the summer wood part 2 as shown in the figure. The tube diameter is considerably larger than that of the conduit.

A veneer with such wood grain can be manufactured from natural ring-hole wood, but it has not been possible to artificially manufacture it using wood other than wood with ring-holes.

That is, if one tries to artificially manufacture this using a wood other than a wood with ring holes, the diameter and arrangement of the conduits that the wood other than the wood with ring holes currently has must be changed.

However, that is not possible.

Therefore, an object of the present invention is to provide a method for manufacturing a decorative veneer having a wood grain pattern similar to that of a ring-hole material without using a ring-hole material.

The feature of this invention is that porous synthetic resin plates with large pores and scattered porous raw wood veneers with small pores are alternately stacked and bonded together, and then these are pressed together using a template to create a flitch. create,
The purpose is to slice this flitch to obtain a decorative veneer.

In other words, by doing this, the synthetic resin porous plate with large pores constitutes the part corresponding to the spring material of the ring-pored material, and the raw wood veneer made of the diffuse-pored material with small pores is formed. constitutes the part corresponding to the summer wood part of the ring-hole material, so the decorative veneer looks like a ring-hole material.

Next, this invention will be explained in detail.

The pore wood veneer having small pores used in this invention is a veneer of wood of a pore wood species such as agathis, parosapis, or pencil fern, which has small diameter ducts.

The thickness of this raw wood veneer is most preferably selected to be 0.6 to 2.0 mm.

A foamed plastic sheet or the like is used as the porous synthetic resin plate having large pores.

These foamed plastic sheets include hard urethane sheets, ABS resin sheets, polystyrene sheets, etc., and the pores (bubbles) of these sheets have a diameter of 0.
The thickness of the sheet is preferably selected to be 0.05 to 0.3 mm, and the thickness of the sheet is preferably selected to be 0.1 to 0.3 mm.

In this case, it is preferable that the thickness of the sheet is about ±0.05 mm and has an uneven thickness.

This is due to the following reason.

In other words, if the sheet has no uneven thickness, the width of the decorative veneer corresponding to the spring material of the ring hole material will be uniform, but if the sheet has uneven thickness, the width of the ring hole material will be uniform. This is because the width of the portion of the decorative veneer corresponding to the spring wood portion becomes thinner or thicker like the width of the spring wood portion of the ring-pored natural precious wood veneer, resulting in a state that approximates natural wood.

In addition, as a porous plate made of synthetic resin with large pores, it is made of polyester resin, polyamide resin, and vinylon and has a diameter of 0.1 to 0.2 mm and a length of 0.5 to 1.0 m.
m capsules may be formed in layers.

Alternatively, a porous plate made of synthetic resin having large pores may be formed by applying a foamable synthetic resin to the veneer surface of a veneer of diffused porous raw wood having small pores.

Note that the mold plate used for molding the flitch, its pressing method, and the slicing of the flitch may be as usual.

Next, examples will be described.

Example 1: First, as shown in Fig. 2, a porous raw wood veneer (Agathis rotary veneer with a thickness of 2.0 mm) 3 with small pores and a synthetic resin porous plate with large pores were prepared. The shaped bodies (hard urethane sheets with a thickness of 0.1 to 0.2 mm) 4 are alternately stacked with adhesive layers 5 interposed therebetween.

Next, this is bonded under pressure using a template having an uneven surface to form an uneven flitch 6 shown in FIG. 3.

Next, when this uneven flitch 6 is sliced in the direction of arrow A, as shown in FIG. A decorative veneer 9 with a ring-hole material appearance is obtained.

Example 2: An ABS citrus sheet with a thickness of 0.1 to 0.2 mm was used in place of the synthetic resin porous plate 4 made of a hard urethane sheet.

Other than that, a decorative veneer with an annular hole material appearance was obtained in the same manner as in Example 1.

Example 3: A polystyrene sheet with a thickness of 0.1 to 0.2 mm was used in place of the synthetic resin porous plate 4 made of a hard urethane sheet.

Other than that, a decorative veneer with an annular hole material appearance was obtained in the same manner as in Example 1.

In addition, in the example, pressure molding was performed using a mold plate with unevenness,
Pressure molding may be performed using a template that does not have such irregularities.

Further, the direction of the slice of the flitch 6 may also be vertical instead of horizontal as shown in FIG.

In that case, a decorative veneer with a straight grain pattern similar to that of ring-hole material can be obtained.
