いう欠点を有していた。 A plurality of material veneers are laminated with an adhesive and bonded by pressure using a concave-convex die to obtain a concave-convex deformed frit, and this concave-convex deformed fritsch is sliced in a predetermined direction to form a layer of each material veneer into an annual ring layer. In the conventional method of obtaining artificial decorative veneers expressed in the form of a board, during the pressure bonding process of laminated material veneers using an uneven mold, the pressing pressure is applied to areas with large and small curvatures of uneven deformation. At this time, the gas generated as the adhesive hardens (CO 2 , etc.) and the air remaining between the layers of each material veneer are not sufficiently dissipated to the outside, resulting in uneven deformation due to the weak pressing pressure. These gases and residual air can cause poor adhesion between the layers in those areas.
したがつて、この発明の目的は、積層素材単板

工化粧単板の製造方法を提供することである。 Therefore, an object of the present invention is to provide a method for manufacturing an artificial decorative veneer that does not cause poor adhesion between the layers of a laminated material veneer.

目状に現われる人工化粧単板を得るものである。 An embodiment of the invention is shown in FIGS. 1 to 6. In other words, the method for manufacturing this artificially decorated veneer is as follows:
As shown in FIG. 1, a plurality of material veneers 2 coated with adhesive using a roll coater 1 or the like are stacked on a flat mold 3 as shown in FIG. Pre-tightening is performed at 1/2 to 1/5 of the clamping pressure and 1/3 to 1/10 of the clamping time of the main clamping.
Thereafter, as shown in FIG. 5, the concave-convex deformed fritches 5 are finally pressed using the concave-convex die 4 as in the conventional case to obtain the concave-convex deformed fritches 5 as shown in FIG.
As shown in the figure, the artificial decorative veneer is sliced with a knife 6 from the direction intersecting the laminated surface to obtain an artificial decorative veneer in which the layers of each material veneer appear in the form of grains on the surface.
前記予備圧締処理における圧締圧力および圧締

どにより異なるが、圧締圧力については５〜40
Kg／cm2が適当である。 The clamping pressure and clamping time in the preliminary clamping process vary depending on the adhesive used and the number of stacked material veneers 2, but the clamping pressure is 5 to 40%.
Kg/cm 2 is appropriate.
接着剤としては、ウレタン樹脂、ユリヤ樹脂、
ユリヤ酢ビ樹脂、フエノール樹脂、メラミン樹
脂、エポキシ樹脂などが適当である。 Adhesives include urethane resin, urea resin,
Suitable examples include urea vinyl acetate resin, phenolic resin, melamine resin, and epoxy resin.
なお、予備圧締を終えた後、本圧締に入る前

ル７で下型４ｂの圧締面に沿うようにしごく工程
を加えもよい。 After completing the preliminary pressing and before starting the main pressing, the material veneer 2 laminated on the lower mold 4b of the uneven mold 4 as shown in FIG. 3 is rolled with a pressing roll as shown in FIG. In step 7, a squeezing process may be added along the clamping surface of the lower die 4b.

る。 Since the laminated material veneers 2 are pre-compacted before the main compaction, the air remaining between the layers of each material veneer 2 is not only dissipated to the outside during this preliminary compaction, but also A part of the gas generated when the adhesive hardens is also dissipated, and this pre-pressing allows the adhesive to penetrate uniformly into each material veneer 2, and in the main pressing, small changes in curvature with weak pressing pressure are achieved. If gas is trapped in curved parts or adhesive is unevenly distributed, this phenomenon will not occur, and each material veneer 2,
Adhesion defects between the two can be significantly reduced.

る。 20 to 50 veneers coated with room temperature curing urethane adhesive (KU224) at a rate of 100 to 200 g/m 2 are laminated, and the pressing conditions are clamping pressure: 2 to 3 kg/cm 2 . Time: After pre-pressing for 5 minutes, this laminated material veneer is placed on the bottom mold of the uneven mold, and the circumferential surface is squeezed with a Teflon-coated rubber roll.
Final pressing is performed with a pressing pressure of 20 kg/cm 2 to obtain an uneven deformed fritchi, which is then sliced into artificial decorative veneers.

きるという効果を有する。 As described above, the method for manufacturing artificial decorative veneers of the present invention includes the adhesive application step of applying adhesive to a material veneer, and the stacking of a plurality of material veneers coated with adhesive and flat molding. There is a preliminary pressing process in which pressure is applied at 1/2 to 1/5 of the pressing pressure and 1/3 to 11/10 of the pressing time, and the pre-pressed laminated material veneer is finally pressed using a concave-convex die. Since the process includes a fritching process to obtain a concave-convex deformed fritz and a slicing process to slice the resulting concave-convex deformed fritz in a predetermined direction, the gas generated as the adhesive hardens during pre-pressing and the space between each material veneer are The remaining air is evenly and sufficiently dissipated, and the adhesive permeates uniformly into the material veneer, preventing gas and air from being trapped or unevenly distributing the adhesive in areas where the pressing pressure is weak during the final pressing. This phenomenon does not occur, and it has the effect that poor adhesion between layers of laminated material veneers can be significantly reduced.
