Description

[Detailed Description of the Invention] (Field of Industrial Application) This invention provides a method for making plywood used for wall materials, flooring, and other decorative surfaces easy to adhere to and inexpensively, without cracking or tearing. The invention relates to a sheet-like veneer.

(Prior Art) Recently, decorative plywood, which is made by thinly slicing wood and pasted onto synthetic wood boards, has come into widespread use because of its natural appearance and excellent surface appearance.

C base tm-i <Key body rises Rokuyami Kaishu) However, since the veneer board mentioned above is made of natural wood, it expands and contracts significantly as it dries and wets, which causes warping etc. in the decorative plywood. , or it has the disadvantage of peeling off from the adhesive surface, and if the veneer is stretched over a metal sash or resin board, the degree of expansion and contraction of the base material may be extreme due to changes in humidity and dryness and temperature. Because they are different from each other, they have the disadvantage of peeling, and if the decorative surface has a part of a square corner, it is difficult to stick them together, causing problems such as cracking or floating surfaces.

(Means for Solving the Problems) This invention has been proposed to solve the above-mentioned problems, in which reinforcing paper 2 is pasted on one side of the back side of an ultra-thin veneer board 1. Furthermore, an extremely thin thermoplastic resin film 3 is attached to the other side of the reinforcing paper 2.

(Function) In the sheet-like veneer constructed in this way, the reinforcing paper 2 is first adhered to the thin veneer 1, so the reinforcing paper 2 prevents the veneer 1 from warping and is easily attached to the film 3. Also, since the veneer 1 is reinforced, there will be no cracking or chipping of the cut edges of the veneer L, and even when rolled into a roll, the veneer 1 will not crack, so when the reinforcing paper 2 is pasted. It is also possible to store the veneer 1 rolled up.

In addition, by adhering the next synthetic resin film 3 to the two sides of this reinforcing paper, the adhesion is very good even without sanding, and the veneer l is effectively reinforced, and the film 3 and reinforcing paper 2 To prevent the veneer 1 from warping.

Further, since the easily stretchable synthetic resin film 3 is prevented from expanding and contracting by the reinforcing paper 2, processing operations such as cutting and pasting of the sheet-like plywood backed with the film 3 are easy to perform.

Furthermore, the reinforcing paper 2 absorbs the moisture on the veneer l, and the reinforcing paper 2 averages it over the entire surface to bring an appropriate amount of moisture to the veneer 1, and the reinforcing paper 2 acts as a buffer between the veneer l and the film 3. Since it is a belt, even if a partial force is applied to the surface of the veneer 1, it is averaged out and no cracks or tears occur.

(Example) Fig. 1 shows an embodiment of the present invention, in which 1 is a veneer board made by thinly slicing natural wood, and as shown in Fig. 2, synthetic paper is first applied to the back side of the veneer board 1. A reinforcing paper 2 made of Japanese paper or the like is pasted. Next, a hard or semi-hard film 3 of thermoplastic synthetic resin such as PVC, Teflon, or nylon is adhered to form a sheet-like veneer.

In some cases, a -q4 reinforcing sheet is attached to the back side of the adhesive surface of the film 3, but usually it is not attached.

(Effects) The sheet-like veneer according to the present invention is constructed as described above. 1. The thin veneer is reinforced with paper and synthetic resin film JI, and the veneer and film are adhered through the paper, and the adhesive properties are improved. Because it is of good quality, it does not peel off, prevents the veneer from warping, prevents the veneer from cracking or tearing, and because it is in the form of a thin sheet, it is easy to attach it to some corners.

2. It is a thin sheet made of wood, paper, and synthetic resin film, so it can be cut freely, and it can also be rolled up into a long roll and stored, so it is possible to install decorative surfaces with few seams. .

3.Since the front side is a veneer and the back side is a synthetic resin film, the back side blocks moisture, and the front veneer does not bulge due to moisture. It is absorbed and averaged by the next layer of paper, so even though the surface veneer is thin, it retains an appropriate amount of moisture and feels good when it comes in contact with it.

4 Medium F between the veneer and the film! tll: The intervening reinforcing paper suppresses the elongation of the film, and both the film and the reinforcing paper prevent the veneer from elongating, and also prevents damage such as cracks by becoming stiff against the force applied to the surface of the veneer. To prevent.

5. It is low cost because it is just a veneer, reinforcing paper, and synthetic resin film bonded together.

They have the following characteristics: pressed sheets, hoe, Tomelt-covered sheets, decorative sheets, flooring materials (foamed materials, etc.), wall materials (insulated materials, etc.), Ideal as a material for cabinet assembly (i.e. pasted on canted particle board).
