Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to a sheet-like material that takes advantage of the natural beauty and good texture of the skin of natural wood, and relates to a sheet-like material that can be substituted for various purposes and a method for producing the same.

[Conventional technology]

Sutra books have been well known since ancient times as thin slices of wood.

Furthermore, there are many methods for producing laminated materials by thinly slicing wood and bonding it to polyvinyl chloride, aluminum, or the like.

[Problem that the invention attempts to solve]

However, sutra books are extremely easy to tear in the vertical direction, and even in the horizontal direction when bent.
Furthermore, there is a limit to their size, and therefore their uses are also limited, and they are usually discarded after one use.

In addition, even in the case of the latter, the surface of the sliced material will crack if it is bent horizontally by 90° or 180°, and although it can be used to some extent when compared to a sutra, it is less flexible and less flexible when used as a secondary material. Due to the lack of strength and durability, it cannot be made into a product that is strong and durable, and therefore its uses are limited to a certain extent.

The present invention basically solves the above-mentioned drawbacks by using a synthetic resin hot melt film as an adhesive layer, which not only makes use of the natural beauty and texture of the wood surface, but also makes it strong. The object of the present invention is to provide a sheet-like material that is flexible and strong and resistant to cracking in the lateral, longitudinal, and forward directions, and that can be used for a further expanded range of uses, and a method for producing the same. shall be.

[Means for Solving the Problems] The above-mentioned problems are solved by the use of sheet-like materials and wood, which are characterized in that a synthetic resin-based fosotomel l-film is fixed as an adhesive layer to a wooden sheet material obtained by thinly slicing wood into sheets. A synthetic resin-based Honmelt film was used as an adhesive to form an adhesive layer on a wooden sheet material thinly sliced into sheets by thermocompression bonding, and a paper-like object was fixed within or on the adhesive layer. The problem is solved by a method of manufacturing a sheet-like material characterized by the following.

〔Example〕

In the embodiment shown in the drawings, a wooden sheet material 1 (about 0.03 to 0.15 mm thick) is first created by thinly slicing wood into sheets. Next, a polyamide hot melt film is thermocompressed at a pressure of about 3 kg/cJ and a temperature of about 110° C. for 40 seconds to fix the polyamide hot melt film to the wooden sheet material 1 as an adhesive layer 2. Further, a paper-like material, in this example, a paper-like material 3 made of non-woven fabric, is placed under the adhesive layer 2 made of polyamide hot film and bonded under heat and pressure under the same conditions to fix the non-woven fabric to the adhesive layer 2. It is something.

In another embodiment, the thickness of the wooden sheet material 1 is approximately 0.
．． 081, the adhesive layer 2 was fixed to the wooden sheet material I by thermocompression bonding using a urethane hot film as the adhesive layer at a pressure of about 7 kg/ct and a temperature of about 90°C for about 30 seconds, and the paper-like material 3 was bonded using this method. In the example, the paper-like material 3 is fixed to the adhesive layer 2 by thermocompression bonding using leaf veins, woven fabric, thin paper, etc. under the same conditions.

In addition, in the present invention, the wooden sheet material was used as it is in order to preserve the natural beauty of the wood, its unique taste and beauty such as the wood texture, wood grain, and texture, and the purpose of using the synthetic resin hot film was It is possible to form a flexible and strong adhesive layer unique to Honmelt film, and compared to impregnating methods using synthetic resin materials, it has superior equipment and work efficiency, and can be manufactured at low cost. This is based on the fact that it not only has these useful properties, but also does not have the odor of organic solvents or the risk of fire, which is the case with liquid adhesives.

Furthermore, it goes without saying that flame retardants, dyes, pigments, antioxidants, ultraviolet absorbers, antifungal agents, etc. may be mixed into the raw materials of this synthetic resin hot melt film depending on the purpose. .

In addition, the synthetic resin hot melt films that can be used in the present invention include all known sheet-like and net-like bot-melt films, but they have various useful effects unique to the present invention, such as adhesion to wood tissue, flexibility, and toughness. In order to achieve this, polyamide-based, polyolefin-based, polyurethane-based, and polyester-based materials are preferred.

Furthermore, the thermocompression bonding of the wooden sheet material 1, the adhesive layer 2, and the paper-like material 3 is not limited to the above-mentioned embodiment; the adhesive layer is first fixed to the wooden sheet material 1, and then In addition to the means for adhering the paper-like body 3, the same effect can be achieved by means for fixing the adhesive layer 2 to the paper-like body 3 and then fixing it to the wooden sheet material 1.

Furthermore, the thickness of the wooden sheet material depends on the type and purpose of the wood,
Although it varies depending on the use, it is preferably about 0.03 m to 0.15 m.

Also, the adhesion or adhesion pressure is 1+r/cwt~10kg
/cl is preferable, and the heating temperature is preferably about 80° C. to 200° C. in order to exhibit the useful effects of the material sheet of the present invention described above.

Furthermore, paper-like materials such as non-woven fabrics are originally used for the purpose of decoration and strength improvement, but the present invention has thermocompression fixation means during the manufacturing process via an adhesive layer! ! ! According to the construction method,
The paper-like material can also be used as a member to expand the material size by joining wooden sheets together, and can also be used to increase the elongation of the thin material itself.
The hardness and tensile strength properties also exhibit a synergistic effect with the excellent properties of the hot melt film, such as flexibility, and help improve the quality and product quality of the material sheet of the present invention.

Note that paper-like materials include, for example, non-woven fabrics, woven fabrics, Japanese and Western paper,
It includes all paper-like materials or synthetic resin film sheet materials made of tissue paper, leaves, leaf veins, etc.

〔Effect of the invention〕

However, according to the present invention, a novel structure and manufacturing method that did not exist in the past, in which a synthetic resin hot melt film is fixed as an adhesive layer to a wooden sheet material, and a paper-like material such as a nonwoven fabric is further fixed to this, is employed. Because of this, it takes full advantage of the natural beauty, texture, and texture of wood, and is also highly flexible and strong, so it does not break when bent horizontally or vertically, and is highly durable. Since it can be set freely even in the middle of the day, it has solved all the drawbacks of not only sutra books but also conventional products of this type mentioned above, and has made it possible to further expand the range of uses. .
