Description

DETAILED DESCRIPTION OF THE INVENTION Object of the Invention (Field of Industrial Application) The present invention relates to a laminated reinforcing material in which, for example, a plurality of thin wood plates are stacked and bonded together.

(Prior art) Conventional laminated reinforcement materials are made by first boiling wood to soften it, then cutting it to form a thin plate like rolling paper, then cutting the thin plate into the desired size. Thereafter, they are forcibly dried, and each sheet is impregnated with an adhesive (for example, phenol-based, melamine-based, urea-based) in a vacuum chamber, and then dried again.

Furthermore, the thin plates are laminated together and heated to 140 to 150℃.
Hot press for about 40 minutes. The laminated reinforcement material formed in this way does not have a glossy or luxurious feel, so it is necessary to paint the surface or
Songs that require additional decorative paper and veneer boards to be pasted.

In addition, since the laminated reinforcing material will warp if it later absorbs moisture, because the thin plates were stacked so that the grains of the sheets alternated, the cross section when cut was dirty and lacked a high-quality feel.

(Problems to be Solved by the Invention) This breakthrough solves the problems that exist in the prior art described above, that is, after the laminated reinforcing material is formed, the surface must be painted or other decorative paper or veneer must be pasted. This is an attempt to solve the problem that the cut surface is dirty, which damages the sense of luxury.

Structure of the Invention (Means for Solving the Problems) In order to solve the above-mentioned problems, this invention impregnates a thin plate with oil, and then laminates and bonds a plurality of the same thin plates with an adhesive to strengthen them under pressure. measures are being taken.

(Function) This invention impregnates thin sheets with oil and strengthens the bond with adhesive, giving it a luxurious and heavy feel, and even when the thin sheets are stacked parallel to each other with their wood grains, moisture such as moisture will be absorbed later. It does not warp, and the wood grain is clearly visible on the cut surface. Further, depending on the case, the wood grains of the thin plates may be overlapped crosswise.

(Example) Hereinafter, an example of a method for manufacturing the laminated reinforcement material of the present invention will be described with reference to the drawings.

First, the wood is boiled to soften it as before.
Stretch the rolling paper in °-'' shape from ' = 1'''5': Cutting - Cut the thin plate 1 of the desired shape, 100~150
Force drying at a temperature of 5-101 minutes. Next, this thin plate 1 is soaked in silicone oil or paraffin oil heated to 1-t-190° C. for 3 to 3.5 hours to impregnate the thin plate 1 with oil. After that, after forced drying at a temperature of 60 to 80°C for 4 hours, an adhesive (for example, phenolic, melamine, or urea type) is applied to the surface, and about 10 sheets, for example, are stacked parallel to the grain of the thin board 1. ~15
The laminated reinforcing material 2 is formed by hot pressing at 0° C. for 30 minutes to 4 hours (the longer the thickness, the longer the time). This laminated reinforcement material 2
Processed to produce door handles, solo pans, floors, pillars, decorative items, etc. At this time, the cutting process of the laminated reinforcing material 2 is better than that of resin due to the oil impregnation.

When impregnating the thin plate 1 with oil, the degree of coloring varies depending on the time, and at the same time, a dye (heat-resistant) is applied.
You can also add color.

The laminated reinforcing material 2 was formed by overlapping the wood grains in parallel, but since it is impregnated with oil, it does not absorb water such as moisture afterwards, so it does not warp.

Also, since the wood grains are layered parallel to each other, the wood grains are clearly visible on the cut surface. In some cases, the wood grain of the thin boards may be crossed. By impregnating it with oil,
It gives a sense of weight, gives a glossy finish, and gives a high-class finish even without painting.

Also, conventional laminated reinforcement manufacturing equipment can be utilized in the embodiments described above.

Although wood was used as the material for the laminated reinforcing material in the above embodiments of the present invention, it may be made of fibers, wood or glass instead of wood. Furthermore, since this laminated reinforcing material does not absorb moisture afterwards, it may be used as an electrical insulating material.

Effects of the Invention As detailed above, in this invention, since the thin plate is impregnated with oil, the inside of the laminated reinforcing material is impregnated, so there is no need to paint it after the laminated reinforcing material is formed. Not only does it give a sense of luxury and weight, but even if the thin sheets are layered so that the wood grains are parallel, they will not absorb moisture later, so they will not warp and the wood grain will be visible on the cut surface. It has the excellent effect of becoming more beautiful and adding to the sense of luxury.
