【発明の詳細な説明】 〔産業の利用分野〕 本発明は天然木化粧板の製造方法に関する。[Detailed description of the invention] [Field of industrial use] The present invention relates to a method for manufacturing natural wood decorative boards.
従来、ゴム、アルダ−等の天然木集成材の表面化粧方法
としては、表面塗装を行なうことにより、木目本来の美
しさを生かしながら表面を保護する方法が用いられてい
た。この塗装工程は、一般に■サンデイングシーラー塗
装■乾燥■サンディング研摩■上塗り塗装を基本工程と
し、塗装感を出すためには更に塗装及びサンディングを
くり返す工程がとられている。Conventionally, as a surface decoration method for natural wood laminated materials such as rubber and alder, a method has been used to protect the surface while making the most of the natural beauty of the wood grain by applying a surface coating. This painting process generally has the following basic steps: - Sanding sealer painting - Drying - Sanding and polishing - Top coat painting, and further repeats painting and sanding to achieve a painted feel.
上記従来技術の塗装による化粧法においては次のような
問題点がある。The above-mentioned prior art cosmetic method by painting has the following problems.
工程が複雑なため、ロスが多く、時間がかかる。Because the process is complicated, there is a lot of loss and it takes time.
従って当然コストも高くなる。また、表面塗装であるた
め、平滑な面及び光沢面を得ることが非常に困難であり

発生が生じるなど、表面物性の点で問題がある。Naturally, therefore, the cost also increases. Furthermore, since it is a surface coating, it is very difficult to obtain a smooth and glossy surface, and many steps are required to achieve such a surface. Additionally, the types of resins commonly used as paintable resins have insufficient hardness and are easily scratched, and if surface hardness is required, special resins and processes are required. If a thick coating is applied, problems arise in terms of surface properties, such as the occurrence of cracks in the coating.
本発明は、上述のような問題点を解決し、表面平滑で表
面物性のすぐれた天然木化粧板を簡単な工程で製造する
ことを目的とする。The object of the present invention is to solve the above-mentioned problems and to manufacture a natural wood decorative board with a smooth surface and excellent surface properties through a simple process.
本発明は、天然木集成材の表面処理方法として、熱硬化

製造法である。That is, the present invention provides a decorative surface of a base material made of laminated natural wood,
This method of producing a natural wood decorative board is characterized by laminating sheets impregnated and dried with a thermosetting resin on a decorative sheet that becomes transparent or translucent after molding, and then hot-pressing molding between hot plates.
本発明について、以下に更に詳しく説明する。The present invention will be explained in more detail below.
第１図に本発明方法によって製造された天然木化粧板の

Note that a backer sheet may be attached to the back surface of the natural wood laminated timber 2 to prevent warping, if necessary.
本発明で基材として使用しうる天然木集成材は、ゴム材
、アルダ−材等の家具用材種の集成材であれば何でもよ
い。集成材の一例を第２図に示す。The natural wood laminated wood that can be used as a base material in the present invention may be any type of laminated wood for furniture such as rubber and alder wood. An example of laminated wood is shown in Figure 2.
集成材の厚さは１０〜３０ｍｎ＋が適当であるが、特に
限定されない。The thickness of the laminated wood is suitably 10 to 30 mm+, but is not particularly limited.
オーバーレイＮ２は、成型後に透明もしくは半透明とな
る化粧シートに熱硬化性樹脂を含浸乾燥させたシートを
基材１上に積層し、熱圧成形することにより形成される
。The overlay N2 is formed by laminating a sheet, which is a decorative sheet that becomes transparent or translucent after molding, impregnated with a thermosetting resin and dried, on the base material 1, and then hot-press molding the sheet.
化粧シートとしては、木材パルプを使用した化粧板用オ
ーバーレイ紙、薄葉紙、合成樹脂バルブ紙、リンター紙
、不織布等の、熱硬化性樹脂を含浸して成型後透明又は
半透明となる１０〜１００ｇ／ｒｒｒ程度、好ましくは
３０〜５０ｇ／ ｎｆの原紙を使用することができる。Decorative sheets include overlay paper for decorative laminates using wood pulp, thin paper, synthetic resin valve paper, linter paper, nonwoven fabric, etc., which are impregnated with thermosetting resin and become transparent or translucent after molding. A base paper of about rrr, preferably 30 to 50 g/nf can be used.
また、化粧シートは、成型後透明又は半透明となる顔料
又は染料を用いて原紙の抄紙工程又は印刷工程等で着色
しておくことも可能である。Further, the decorative sheet can be colored using a pigment or dye that becomes transparent or translucent after molding, during the papermaking process or printing process of the base paper.
上記化粧シートに含浸するための熱硬化性樹脂としては
、メラミン／ホルムアルデヒド樹脂、ジアリルフタレー
ト （ＤＡＰ）樹脂、ベンゾグアナミン樹脂、アセトグ
アナミン樹脂、ポリエステル樹脂等が例示できる。Examples of the thermosetting resin for impregnating the decorative sheet include melamine/formaldehyde resin, diallyl phthalate (DAP) resin, benzoguanamine resin, acetoguanamine resin, and polyester resin.
上記熱硬化性樹脂を化粧シートに含浸する工程において
は、通常化粧板用原紙を含浸する含浸機を使用でき、樹
脂付着量としては使用する化粧シート重量の等量から約
３倍位までの量を用いればよい。このようにして熱硬化
性樹脂を含浸した化粧シートは、例えば８０〜１２０°
Ｃで９０〜１２０秒の条件で乾燥を行なえばよい。In the process of impregnating the decorative sheet with the thermosetting resin mentioned above, an impregnating machine that normally impregnates base paper for decorative laminates can be used, and the amount of resin deposited is from the same amount to about three times the weight of the decorative sheet used. You can use The decorative sheet impregnated with the thermosetting resin in this way has an angle of 80 to 120 degrees, for example.
Drying may be performed at C for 90 to 120 seconds.
次に、乾燥させた熱硬化性樹脂含浸シートを、前記基材
に積層し、熱圧成型を行なう。熱圧成型は通常の成型用
プレスを使用することができ、例えばメラミン樹脂を使
用した場合の低圧メラミン成型では、多段式においては
温度１５０°Ｃ１圧力１５〜２０ｋｇ／Ｃ１１１、時間
８〜ｌＯ分の条件で、また単段式（ショートサイクル方
式）においては温度１８０〜１９０°Ｃ１圧力２０〜２
５ｋｇ／ｃＩＩＩ、時間１分〜１分３０秒の成型条件で
熱圧成型すればよい。またＤＡＰの成型では、多段式で
温度１３０〜１３５°Ｃ１圧力８〜１０ｋｇ／ｃｄ、時
間１０〜１５分の成型条件で熱圧成型する。Next, the dried thermosetting resin-impregnated sheet is laminated on the base material, and hot pressure molding is performed. For hot-press molding, a normal molding press can be used. For example, in low-pressure melamine molding when using melamine resin, in a multi-stage method, the temperature is 150°C, the pressure is 15-20 kg/C, and the time is 8-10 min. In the single-stage type (short cycle type), the temperature is 180-190°C, the pressure is 20-2
Hot-pressure molding may be performed under molding conditions of 5 kg/cIII and time of 1 minute to 1 minute and 30 seconds. In addition, when molding DAP, hot-pressure molding is performed in a multi-stage molding process at a temperature of 130 to 135° C., a pressure of 8 to 10 kg/cd, and a time of 10 to 15 minutes.
熱圧成型においては通常、鏡面板を使用するが、鏡面板
としてフラットな板を用いれば平滑な表面に仕上げるこ
とができ、鏡面板の種類によって、艶、表面性を簡単に
変更することができる。例えば表面にテクスチュアをつ
けたエンボス版の使用も可能である。Normally, a mirror plate is used in hot pressure molding, but if a flat plate is used as the mirror plate, a smooth surface can be achieved, and the gloss and surface properties can be easily changed depending on the type of mirror plate. . For example, it is also possible to use an embossed plate with a textured surface.
本発明によって製造される天然木化粧板は、デスクの天
板、側板、テーブルトップ、家具の扉等に用いるのに適
している。The natural wood decorative board produced according to the present invention is suitable for use in desk tops, side panels, table tops, furniture doors, and the like.
本発明の製造法によれば、化粧シートに熱硬化性樹脂を
含浸、乾燥したものを、通常のプレス機を用いて基材表
面に熱圧成型するだけでよく、工程が単純化される。According to the manufacturing method of the present invention, it is only necessary to impregnate a decorative sheet with a thermosetting resin, dry it, and then hot-press mold it onto the surface of a base material using an ordinary press machine, which simplifies the process.
また、熱硬化性樹脂を基材表面にオーバーレイするため
、塗装を行なったものと同様な肉持感及び意匠感を有し
ながら、表面硬度が高く、傷がつきにくい。In addition, since the thermosetting resin is overlaid on the surface of the base material, it has a texture and design similar to that of a painted product, but has a high surface hardness and is difficult to scratch.
さらに、熱硬化性樹脂をオーバーレイ紙等の化粧シート
に含浸させているため、繊維強化され、クラック等を生

On this surface, an impregnated paper made by impregnating Kojin overlay paper OL-P (42g/%) with diallyl phthalate resin (impregnation rate 78%) using a normal impregnation machine was laminated. Using a glossy Shuramin board as a mirror plate, press molding is carried out using a low-pressure multi-stage press at a press temperature of 135° C., a pressure of 10 kg/c 1 M, and a time of 15 minutes. The obtained molded board was a natural wood decorative board with a smooth surface and a textured feel. This decorative board is JAS (Japanese Agriculture and Forestry Standards)
When surface physical property tests were conducted based on the FW type, all of the tests passed, confirming that the surface properties were equivalent to those of general thermosetting resin decorative laminates (DAP decorative laminates).
本発明によれば、煩雑な工程を要していた従来の塗装工
