Description
本発明は、住宅、店舗、オフィス等の家具、建具、什器、新幹線等の車両の前後の仕切りなど用いられる深凹凸化粧シートに関する。更に詳しくは、化粧シートの裏面がフラットであり、エンボス版の凹凸再現性、寸法安定性、化粧シートの巻き取り適性に優れた深凹凸化粧シートに関する。 The present invention relates to a deep concavo-convex decorative sheet used for furniture such as houses, stores, offices, etc., front and rear partitions of vehicles such as furniture, furniture, and bullet trains. More specifically, the present invention relates to a deep concavo-convex decorative sheet in which the back surface of the decorative sheet is flat, and has excellent concavo-convex reproducibility, dimensional stability of the embossed plate, and excellent suitability for winding the decorative sheet.
化粧シートの表面にエンボス凹凸を設ける方法としては、ポリプロピレン樹脂、ポリエチレン樹脂、共重合ポリエステル樹脂、非晶状態の結晶性ポリエステル樹脂、アクリル樹脂、アクリロニトリル−ブタジエン−スチレン共重合樹脂などの熱可塑性樹脂からなる化粧シートの表面側の樹脂層を溶融押出して積層しつつエンボスロールにて凹凸を設け、その後硬化型樹脂を表面に塗工、硬化して表面保護層を形成する方法が知られている。 As a method for providing embossed irregularities on the surface of the decorative sheet, thermoplastic resins such as polypropylene resin, polyethylene resin, copolymer polyester resin, amorphous crystalline polyester resin, acrylic resin, and acrylonitrile-butadiene-styrene copolymer resin are used. There is known a method in which a resin layer on the surface side of the decorative sheet is melt-extruded and laminated to provide unevenness with an embossing roll, and then a curable resin is applied to the surface and cured to form a surface protective layer.
しかしながらエンボス後に表面保護層を形成すると形成した凹凸を埋めるように塗工することとなり、スキージなどで余分な硬化型樹脂を履き取ったとしてもやはりシャープな表面エンボスの再現が薄れるという問題があった。 However, if a surface protective layer is formed after embossing, it will be applied to fill the formed irregularities, and even if extra curable resin is worn with a squeegee etc., there is still a problem that the reproduction of sharp surface embossing will fade .
複数の熱可塑性樹脂シートを積層してから表面に硬化型樹脂を塗工、硬化させた後に表面からエンボスを付与して表面エンボスを有する化粧シートを製造する方法も知られている。しかし化粧シート全体として硬いシートとすると、ロールで製造した後での巻き取り適性に欠けるものとなり、表面保護層以外を柔らかいものとするとエンボスにより設ける凹凸が化粧シート裏面へ裏抜けし、この化粧シートを化粧板基材に貼り合わせる場合などの密着性に問題があった。
本発明は前記問題点を解決するためになされたものであり、その課題とするところは、化粧シートの巻き取り適性に優れ、化粧シート裏面への凹凸の裏抜けの問題もない、深くてシャープな表面エンボスを有する化粧シートを製造する方法を提供することにある。 The present invention has been made in order to solve the above-mentioned problems, and the problem is that the decorative sheet is excellent in winding-up property, and there is no problem of uneven projection on the back surface of the decorative sheet. Another object of the present invention is to provide a method for producing a decorative sheet having a surface embossing.
本発明はこの課題を解決するものであり即ち請求項１記載の発明は、ポリプロピレン樹脂、ポリエチレン樹脂、共重合ポリエステル樹脂、非晶状態の結晶性ポリエステル樹脂、アクリル樹脂、アクリロニトリル−ブタジエン−スチレン共重合樹脂のいずれかの熱可塑性樹脂からなる化粧シートの製造方法であって、前記熱可塑性樹脂からなる着色熱可塑性樹脂層の表面に絵柄模様を印刷し、この上に接着剤を塗布、乾燥し、さらにこの上に前記熱可塑性樹脂からなる透明熱可塑性樹脂層を押出しラミネートし、最後にこの上に表面保護層として硬化型樹脂と添加剤からなる樹脂を塗工、硬化し、前記着色熱可塑性樹脂層の裏面に、表面をマット処理した２軸延伸ポリエステルフィルムを重ね合わせ、重ね合わせた状態で、エンボス版と熱圧ロールにて、前記表面保護層側より最大深さ約１００μｍの表面エンボスを設けてなることを特徴とする、表面エンボスを有する化粧シートの製造方法である。 The present invention solves this problem, that is, the invention described in claim 1 is a polypropylene resin, a polyethylene resin, a copolymerized polyester resin, an amorphous crystalline polyester resin, an acrylic resin, an acrylonitrile-butadiene-styrene copolymer. A method for producing a decorative sheet made of any one of the thermoplastic resins, printing a pattern on the surface of the colored thermoplastic resin layer made of the thermoplastic resin, applying an adhesive thereon, drying, Further, a transparent thermoplastic resin layer made of the thermoplastic resin is extruded and laminated thereon, and finally a resin comprising a curable resin and an additive is applied and cured as a surface protective layer thereon, and the colored thermoplastic resin is cured. A biaxially stretched polyester film with a matte surface is laminated on the backside of the layer, and the embossed plate and hot At Le, characterized by comprising providing a surface embossing of the maximum depth of about 100μm from the surface protective layer side, a method for producing a decorative sheet having a surface embossed.
本発明はその請求項１に記載の発明により、２軸延伸ポリエステルフィルムの引張弾性率が約４ＧＰａ程度で、化粧シートの熱可塑性樹脂がポリプロピレン樹脂、ポリエチレン樹脂、共重合ポリエステル樹脂、非晶状態の結晶性ポリエステル樹脂、アクリル樹脂、アクリロニトリル−ブタジエン−スチレン共重合樹脂のいずれかであり、これらの引っ張り弾性率が１〜２ＧＰａ程度の為、凹凸を付与しても寸法変化しにくく、且つ、凹凸の裏抜け少なくなる効果がある。且つ化粧シート製造時に容易に巻き取ることが出きるのでロール−ツーロールでの生産が容易になる効果がある。 According to the present invention, the biaxially stretched polyester film has a tensile modulus of about 4 GPa and the decorative sheet thermoplastic resin is a polypropylene resin, a polyethylene resin, a copolyester resin, or an amorphous state. It is one of crystalline polyester resin, acrylic resin, acrylonitrile-butadiene-styrene copolymer resin, and the tensile elastic modulus is about 1 to 2 GPa. There is an effect to reduce the amount of strikethrough. In addition, since it can be easily wound up at the time of manufacturing the decorative sheet, there is an effect that the production by roll-to-roll is facilitated.
以下、本発明を図面に基づき詳細に説明する。図１に本発明の化粧シートの製造方法におけるエンボス付与の状態を示す。２軸延伸ポリエステルフィルム１０を背面に貼り合せた状態として、着色熱可塑性樹脂層１と絵柄模様による絵柄層２と接着剤による接着剤層３と透明熱可塑性樹脂層４と表面保護層５を有する化粧シートとなっている状態で、表面からエンボス版２０の凹凸部２１により表面にエンボスを設け、その後背面から２軸延伸ポリエステルフィルム１０を剥がしていく状態を示している。 Hereinafter, the present invention will be described in detail with reference to the drawings. FIG. 1 shows a state of embossing in the method for producing a decorative sheet of the present invention. As a state in which the biaxially stretched polyester film 10 is bonded to the back surface, it has a colored thermoplastic resin layer 1, a pattern layer 2 with a pattern, an adhesive layer 3 with an adhesive, a transparent thermoplastic resin layer 4, and a surface protective layer 5. In the state where it is a decorative sheet, embossing is provided on the surface from the surface by the concavo-convex portion 21 of the embossing plate 20, and then the biaxially stretched polyester film 10 is peeled off from the back surface.
本発明における２軸延伸ポリエステルフィルム１０はその表面をマット処理したものを用いる。これにより化粧シートの表裏に対して、表面側のエンボス版の摩擦係数より大きいものとなり、化粧シートがエンボス版２０を押し付けても動かず、凹凸付与の再現性と残留応力が少なくなるので、剥離後のシボ戻りもし難くなり、凹凸の裏抜けがなくなる。 The biaxially stretched polyester film 10 according to the present invention uses a matte surface. As a result, the front and back of the decorative sheet are larger than the coefficient of friction of the embossed plate on the front side, and the decorative sheet does not move even when the embossed plate 20 is pressed, and the reproducibility of unevenness and the residual stress are reduced. It will be difficult to return to the wrinkle later, and the unevenness will not be lost.
本発明における着色熱可塑性樹脂層１としては、ポリ塩化ビニル樹脂、非晶状態の結晶性ポリエステル樹脂、非結晶性ポリエステル樹脂、２軸延伸ポリエステル樹脂、ポリプロピレン樹脂、ポリエチレン樹脂などからなる単層あるいは複数の層からなるものが用いられる。着色熱可塑性樹脂層１の厚みは、ハンドリング性、刃物摩滅度などを考慮すると、５０〜２００μｍが望ましく、特に取り扱いやすさと剥離時の切れにくさから１２〜２５μｍが最適である。 The colored thermoplastic resin layer 1 in the present invention is a single layer or a plurality of layers made of polyvinyl chloride resin, amorphous crystalline polyester resin, amorphous polyester resin, biaxially stretched polyester resin, polypropylene resin, polyethylene resin, or the like. Those composed of the following layers are used. The thickness of the colored thermoplastic resin layer 1 is preferably 50 to 200 μm in view of handling properties, blade abrasion, and the like, and is most preferably 12 to 25 μm because it is easy to handle and difficult to cut at the time of peeling.

The thickness of the transparent thermoplastic resin layer 4 is preferably 70 to 200 μm in consideration of weather resistance, heat resistance, ease of winding, scratch resistance, and the like.
表面保護層５としては、公知の紫外線硬化型樹脂や２液ウレタン樹脂が使用可能であり、これらに適宜ベンゾトリアゾール系、トリアジン系紫外線吸収剤、ヒンダードアミン系光安定剤、ガラスビーズなどを適宜添加する。表面保護層５の厚みは、耐衝撃性試験、耐キャスター性試験の復元性を考慮すると、乾燥後の塗布量で６〜１５ｇ／ｍ２程度が好適である。 As the surface protective layer 5, known ultraviolet curable resins and two-component urethane resins can be used, and benzotriazole-based, triazine-based ultraviolet absorbers, hindered amine light stabilizers, glass beads and the like are appropriately added thereto. . The thickness of the surface protective layer 5 is preferably about 6 to 15 g / m 2 in terms of the coating amount after drying in consideration of the resilience of the impact resistance test and caster resistance test.
このようにして得た化粧シートとその背面の２軸延伸ポリエステルフィルムを、エンボス版２０にて表面にエンボスを付与する。エンボス版の加熱温度は１３０℃程度とするのが好適である。これにより化粧シートが５０〜１００℃程度に熱せられた状態となり、これにより表面にエンボスを設け、その後２軸延伸ポリエステルフィルムを剥離することで凹凸の裏抜けは殆ど発生しなくなる。その後、化粧シートを冷却する。 The decorative sheet thus obtained and the biaxially stretched polyester film on the back surface thereof are embossed on the surface with an embossed plate 20. The heating temperature of the embossed plate is preferably about 130 ° C. As a result, the decorative sheet is heated to about 50 to 100 ° C., whereby embossing is provided on the surface, and then the biaxially stretched polyester film is peeled off, so that there is almost no uneven penetration. Thereafter, the decorative sheet is cooled.
着色熱可塑性樹脂層１として厚み７０μｍのポリオレフィン樹脂着色シート（リケンテクノス（株）製：「リベストＴＰＯ」）を用い、これに絵柄層２としてグラビア印刷機にて２液ウレタン樹脂バインダーインキを用いた木目柄印刷を行なった。
この絵柄層２上に接着剤層３として、ポリエステルポリオール１００重量部にヘキサメチレンジイソシアネート（硬化剤）を１３重量部混合したものを用い、乾燥後の重量が１ｇ／ｍ２となるように塗工した。そして、この上に透明熱可塑性樹脂層４としてポリプロピレン樹脂を厚み７０μｍとなるように押出ラミネートした。
