Description
本発明は、キッチン用部材、鋼板ラミネート用シート、建築内装材、外装材、アルミニウム基材へのラッピング用シート、木質系基材への積層、ラッピング、真空成形用に使われる光輝性化粧シートに関する。 The present invention relates to a member for kitchen, a sheet for laminating steel sheets, an architectural interior material, an exterior material, a sheet for wrapping to an aluminum base material, a lamination to a wooden base material, wrapping, and a glittering decorative sheet used for vacuum forming. .
従来、熱可塑性樹脂基材や薄紙、チタン紙、含浸紙に光輝性を出そうとして光輝性顔料により絵柄模様を印刷することは行われていた。しかしながら、光輝性顔料での全面ベタ印刷は、塗布、塗工の安定性が良くないことから、ムラ、スジ、抜け(インプレッションロールの傷などの凹凸による)などが生じやすかった。また、全面ベタ光輝性顔料層がギラギラしすぎ、光輝性顔料の白っぽさが生じることが多かった。 Conventionally, it has been practiced to print a pattern with a glittering pigment so as to provide glitter on a thermoplastic resin substrate, thin paper, titanium paper or impregnated paper. However, since the solid printing with the glitter pigment is not stable in coating and coating, unevenness, streaks, omission (due to irregularities such as scratches on the impression roll) and the like are likely to occur. In addition, the entire solid glitter pigment layer was too glaring, and the whitishness of the glitter pigment often occurred.
光輝性顔料としての原材料の検討がなされたり、塗布、塗工方法を検討するということがなされているが、十分な安定性を得るにはいたっていない。 Although raw materials as glitter pigments have been studied and application and coating methods have been studied, sufficient stability has not been achieved.

Thin paper, titanium paper, and impregnated paper may be used as the paper substrate. Examples of the resin include polyolefin resins such as polyethylene, polypropylene, polymethylpentene, polybutene, ethylene-propylene copolymer, ethylene-α-olefin copolymer, propylene-α-olefin copolymer, and ethylene-vinyl acetate copolymer. Olefin copolymer resins such as polymers, ethylene-vinyl alcohol copolymers, ethylene- (meth) acrylic acid (ester) copolymers, ethylene-unsaturated carboxylic acid copolymer metal neutralized products (ionomers), etc. Polyolefin resin, polyethylene terephthalate, polybutylene terephthalate, polytetramethylene terephthalate, polyethylene naphthalate, polyethylene terephthalate-isophthalate copolymer, 1,4-cyclohexanedimethanol copolymer polyethylene terephthalate Rate, polyarylate, polyester resins such as polycarbonate, poly (meth) acrylonitrile, polymethyl (meth) acrylate, polyethyl (meth) acrylate, polybutyl (meth) acrylate, acrylic resins such as polyacrylamide, 6-nylon, 6, Polyamide resins such as 6-nylon, 6,10-nylon, styrene resins such as polystyrene, AS resin, ABS resin, vinyl resins such as polyvinyl chloride, polyvinyl acetate, polyvinyl alcohol, polyvinyl acetal, polyvinyl butyral, Fluorine resins such as polyvinyl fluoride, polyvinylidene fluoride, polytetrafluoroethylene, ethylene-tetrafluoroethylene copolymer, ethylene-perfluoroalkyl vinyl ether copolymer, etc., or two or more thereof Mixtures, copolymers, can be used complex, a laminate or the like.
上記の各種の熱可塑性樹脂の中でも、近年の環境問題に対する社会的な関心の高まりに鑑みれば、ポリ塩化ビニル樹脂等の様な塩素(ハロゲン)を含有する樹脂の採用は望ましいものではなく、非ハロゲン系の熱可塑性樹脂を採用することが望ましい。中でも各種物性や加工性、汎用性、経済性等の面からは、ポリオレフィン系樹脂またはポリエステル系樹脂(非晶質又は二軸延伸)を使用することが最も望ましい。これらのうちポリオレフィン系樹脂は、従来よりポリ塩化ビニル樹脂を代替する光輝性化粧シート用材料として採用が進んでいたものの、切削加工性の悪さが目立つことが指摘されて来たが、本発明によって切削加工性の格段の改善が可能となり、本発明の効果が最も顕著に発現する素材である。 Among the above-mentioned various thermoplastic resins, in view of the increasing social interest in environmental problems in recent years, it is not desirable to use a resin containing chlorine (halogen) such as polyvinyl chloride resin. It is desirable to employ a halogen-based thermoplastic resin. Among these, from the viewpoints of various physical properties, processability, versatility, economy, etc., it is most desirable to use polyolefin resin or polyester resin (amorphous or biaxial stretching). Of these, polyolefin resins have been pointed out to be conspicuously poor in machinability, although they have been adopted as glittering decorative sheet materials that replace polyvinyl chloride resins. It is a material that can remarkably improve the machinability and exhibits the effect of the present invention most remarkably.
上記ポリオレフィン系樹脂としては、既に列挙した様に多くの種類のものが知られており、それらの中から光輝性化粧シートの使用目的等に応じて適宜選択して使用すれば良いが、中でも一般的な用途に最も好適なのは、ポリプロピレン系樹脂、すなわちプロピレンを主成分とする単独または共重合体であり、具体的には、例えばホモポリプロピレン樹脂、ランダムポリプロピレン樹脂、ブロックポリプロピレン樹脂等を単独または適宜配合したり、それらにさらにアタクチックポリプロピレンを適宜配合した樹脂等を使用することができる。また、プロピレン以外のオレフィン系単量体を含む共重合体であってもよく、例えば、ポリプロピレン結晶部を有し、且つプロピレン以外の炭素数2〜20のα−オレフィン、好ましくはエチレン、ブテン−1、4−メチルペンテン−1、ヘキセン−1またはオクテン−1、のコモノマーの1種または2種以上を15モル%以上含有するプロピレン−α−オレフィン共重合体などを例示することができる。また、通常ポリプロピレン系樹脂の柔軟化に用いられている低密度ポリエチレン、エチレン−α−オレフィン共重合体、エチレン−プロピレン共重合ゴム、エチレン−プロピレン−非共役ジエン共重合ゴム、スチレン−ブタジエン共重合体またはその水素添加物等の改質剤を適宜添加することもできる。 As the above-mentioned polyolefin resin, many types are known as already listed, and it may be used by appropriately selecting from them according to the purpose of use of the glittering decorative sheet. The most suitable for typical use is a polypropylene resin, that is, a propylene-based single or copolymer, specifically, for example, a homopolypropylene resin, a random polypropylene resin, a block polypropylene resin, etc. In addition, a resin or the like in which atactic polypropylene is appropriately blended with them can be used. Further, it may be a copolymer containing an olefin monomer other than propylene, for example, an α-olefin having a polypropylene crystal part and having 2 to 20 carbon atoms other than propylene, preferably ethylene, butene- Examples thereof include a propylene-α-olefin copolymer containing 15 mol% or more of one or more comonomers of 1,4-methylpentene-1, hexene-1 or octene-1. In addition, low density polyethylene, ethylene-α-olefin copolymer, ethylene-propylene copolymer rubber, ethylene-propylene-nonconjugated diene copolymer rubber, styrene-butadiene copolymer, which are usually used for softening polypropylene resins. A modifier such as a coalescence or a hydrogenated product thereof can be appropriately added.
基材1には、必要に応じて例えば着色剤、充填剤(シリカ、タルク、酸化チタン、硫酸バリウム等)紫外線吸収剤、光安定剤、熱安定剤、酸化防止剤、帯電防止剤、滑剤(ステアリン酸、金属石けん等)、難燃剤、抗菌剤、防黴剤、減摩剤、光散乱剤、艶調整剤等の各種の添加剤から選ばれる1種以上が添加されていても良い。なお、基材1は、光輝性化粧シートを貼り合わせる基板などの表面の色のばらつきや欠陥等を隠蔽するために、隠蔽性の不透明に着色されたものが用いられる場合が多いが、基板の表面の質感を活かすために、透明乃至半透明のものが用いられる場合もある。 For the substrate 1, for example, a colorant, a filler (silica, talc, titanium oxide, barium sulfate, etc.), an ultraviolet absorber, a light stabilizer, a heat stabilizer, an antioxidant, an antistatic agent, a lubricant (as necessary) 1 type or more chosen from various additives, such as a stearic acid, a metal soap, a flame retardant, an antibacterial agent, an antifungal agent, an anti-friction agent, a light scattering agent, and a gloss adjusting agent, may be added. In addition, the base material 1 is often used in order to conceal the color variation or defects on the surface of the substrate or the like to which the glittering decorative sheet is attached, but the substrate 1 is opaquely colored. In order to make use of the surface texture, a transparent or translucent material may be used.
第一全面ベタ着色層2、第二全面ベタ着色層4、及び第三全面ベタ着色層5は、本発明の光輝性化粧シートに絵柄による意匠性を付与するために、必要に応じて設けられるものであり、基材1自体の着色で代用できる場合等には省略も可能である。この第一全面ベタ着色層2は、染料または顔料等の着色剤を適当なバインダー樹脂と共に適当な希釈溶媒中に溶解または分散してなる印刷インキまたは塗料等を使用して、例えばグラビア印刷法またはオフセット印刷法等の各種印刷法や、グラビアコート法またはロールコート法等の各種塗工法などによって形成されるのが一般的である。バインダー樹脂としては、例えばウレタン系樹脂、アクリル系樹脂、塩化酢酸ビニル系樹脂、ポリイミド系樹脂、硝化綿等またはそれらの混合物等がよく使用されるが、勿論これらに限定されるものではない。絵柄の種類は、例えば木目柄、石目柄、布目柄、抽象柄、幾何学模様、文字または記号、それらの組み合わせ等、所望により任意であり、単色無地であっても良い。また、光輝性化粧シートの隠蔽性を向上するために、第一全面ベタ着色層2の裏面側に、二酸化チタンや酸化鉄等の不透明顔料を多く含む不透明な印刷インキまたは塗料による隠蔽層が併設される場合もある。特に、第二全面ベタ着色層4は、全面ベタ光輝性顔料層3がギラギラしすぎ、光輝性顔料の白っぽさが生じることが無いように乾燥後の塗布量で0.5〜2g/m2であることが望ましい。 The 1st whole surface solid colored layer 2, the 2nd whole surface solid colored layer 4, and the 3rd whole surface solid colored layer 5 are provided as needed, in order to provide the designability by a picture to the glittering decorative sheet of the present invention. However, it can be omitted if the base material 1 itself can be colored. The first whole surface solid colored layer 2 is formed by using, for example, a gravure printing method or a printing ink or paint obtained by dissolving or dispersing a colorant such as a dye or a pigment in a suitable diluent solvent together with a suitable binder resin. It is generally formed by various printing methods such as an offset printing method and various coating methods such as a gravure coating method or a roll coating method. As the binder resin, for example, urethane resin, acrylic resin, vinyl chloroacetate resin, polyimide resin, nitrified cotton, or a mixture thereof is often used, but it is not limited thereto. The type of the pattern is arbitrary as desired, for example, a wood grain pattern, a stone pattern, a cloth pattern, an abstract pattern, a geometric pattern, a character or a symbol, a combination thereof, etc., and may be a solid color. In addition, in order to improve the concealing property of the glittering decorative sheet, a concealing layer made of an opaque printing ink or paint containing a large amount of opaque pigments such as titanium dioxide and iron oxide is provided on the back side of the first full-colored colored layer 2. Sometimes it is done. In particular, the second whole surface solid colored layer 4 is 0.5 to 2 g / in coating amount after drying so that the whole surface solid glitter pigment layer 3 is not too bright and the whitish of the glitter pigment does not occur. m 2 is desirable.
全面ベタ光輝性顔料層3に用いる光輝性顔料としては、天然の雲母に酸化チタン、酸化鉄などの金属酸化物を被覆したパール顔料が好適に使用可能であり、その他アルミ粉等の金属粉も使用可能である。粒径は1〜40μmのものを用い、好ましくは5〜30μm、特には平均粒径30μmで粒径にばらつきの少ないものが最適である。1μmより小さいと十分な光輝性が発現されず、40μmより大きいとムラやスジなどの不具合が発生し易くなる。
印刷方法としては、グラビア印刷、マイクログラビア印刷、ファニッシャーロール印刷、オフセット印刷、インキジェット印刷、シルクスクリーン印刷等で行うことができる。層厚は、乾燥後の塗布量で1〜3g/m2となるように設ける、特には2g/m2が最適である。1g/m2より薄いと十分な光輝性が発現されず、3g/m2より厚いと抜けなどの不具合が発生し易くなる。
As the bright pigment used for the entire solid bright pigment layer 3, a pearl pigment in which natural mica is coated with a metal oxide such as titanium oxide or iron oxide can be suitably used, and other metal powders such as aluminum powder can also be used. It can be used. A particle size of 1 to 40 μm is used, preferably 5 to 30 μm, and particularly an average particle size of 30 μm with a small variation in particle size is optimal. If it is smaller than 1 μm, sufficient glitter is not expressed, and if it is larger than 40 μm, defects such as unevenness and streaks tend to occur.
As a printing method, gravure printing, microgravure printing, finisher roll printing, offset printing, ink jet printing, silk screen printing, and the like can be performed. The layer thickness is provided so as to be 1 to 3 g / m 2 of the coating amount after drying, in particular at best 2 g / m 2. When it is thinner than 1 g / m 2 , sufficient glitter is not expressed, and when it is thicker than 3 g / m 2 , defects such as omission tend to occur.
接着剤層6は、基材1と透明熱可塑性樹脂層7とを接着させるために、必要に応じて設けられるものであり、他の層が有する接着性を利用可能な場合には省略も可能である。接着剤層6に使用する接着剤の種類には特に制限はないが、イソシアネート系硬化剤を使用する2液硬化型ウレタン系接着剤を使用することが最も望ましい。具体的には、主剤としては例えばポリエステルポリオールまたはポリエーテルポリオール等、硬化剤としてはトリレンジイソシアネート、ジフェニルメタンジイソシアネート、キシリレンジイソシアネート、ヘキサメチレンジイソシアネート、イソホロンジイソシアネート等を使用することができる。 The adhesive layer 6 is provided as necessary in order to bond the base material 1 and the transparent thermoplastic resin layer 7, and may be omitted when the adhesiveness of other layers can be used. It is. Although there is no restriction | limiting in particular in the kind of adhesive agent used for the adhesive bond layer 6, It is most desirable to use the 2 liquid curing type urethane adhesive which uses an isocyanate type hardening | curing agent. Specifically, for example, polyester polyol or polyether polyol can be used as the main agent, and tolylene diisocyanate, diphenylmethane diisocyanate, xylylene diisocyanate, hexamethylene diisocyanate, isophorone diisocyanate, or the like can be used as the curing agent.
なお、接着剤層6は、第二全面ベタ着色層4上に配置されているが、これは通常の製造手順、つまり第一全面ベタ着色層2、全面ベタ光輝性顔料層3、乾燥後の塗布量で0.5〜2g/m2第二全面ベタ着色層4をこの順に有する化粧シートを形成した後に接着剤層6を介して透明熱可塑性樹脂層7と積層する製造手順を想定したものであって、この配置に限定されるものではない。つまり、製造手順は任意であり、例えば、第一全面ベタ着色層2の下面に第三全面ベタ着色層5を形成し、これを接着剤層6を介して基材1上に積層するなどの製造手順とすることも可能である。 The adhesive layer 6 is disposed on the second whole surface solid colored layer 4, which is a normal manufacturing procedure, that is, the first whole surface solid colored layer 2, the whole surface solid glitter pigment layer 3, and after drying. Assuming a manufacturing procedure in which a decorative sheet having the second whole surface solid colored layer 4 in this order is formed in a coating amount of 0.5 to 2 g / m 2 and then laminated with the transparent thermoplastic resin layer 7 via the adhesive layer 6 However, it is not limited to this arrangement. That is, the manufacturing procedure is arbitrary. For example, the third whole surface solid colored layer 5 is formed on the lower surface of the first whole surface solid colored layer 2, and this is laminated on the base material 1 via the adhesive layer 6. It is also possible to use a manufacturing procedure.
プライマー層(図に指示無し)は、本発明の光輝性化粧シートを貼り合わせる基板への接着に使用される接着剤との密着性を向上させるために、必要に応じて施されるものである。基板として最も一般的な木質基材などへの接着剤としては、例えば酢酸ビニルエマルジョン系や2液硬化型ウレタン系などの接着剤が汎用されているので、プライマー層はこれら汎用接着剤に合わせた樹脂設計とすることが望ましい。具体的には、例えばウレタン系、アクリル系、エチレン−酢酸ビニル共重合体、塩化ビニル−酢酸ビニル共重合体系、ポリエステル系等を挙げることができ、中でもポリエステルポリオールとイソシアネート化合物との配合による2液硬化型ウレタン系のプライマー剤などが有効である。また、例えばシリカや硫酸バリウム、炭酸カルシウム等の無機質粉末を添加すると、巻取保存時のブロッキングの防止や、投錨効果による接着力の向上などに有効である。 The primer layer (no instruction in the figure) is applied as necessary in order to improve the adhesion with the adhesive used for bonding to the substrate to which the glittering decorative sheet of the present invention is bonded. . As an adhesive to the most common wood substrate as a substrate, for example, an adhesive such as a vinyl acetate emulsion type or a two-component curable urethane type is widely used. Therefore, the primer layer is adapted to these general-purpose adhesives. It is desirable to have a resin design. Specifically, for example, urethane-based, acrylic-based, ethylene-vinyl acetate copolymer, vinyl chloride-vinyl acetate copolymer system, polyester-based and the like can be mentioned. Among them, two liquids by blending polyester polyol and isocyanate compound A curable urethane primer is effective. Further, for example, addition of inorganic powder such as silica, barium sulfate, calcium carbonate, etc. is effective for preventing blocking during winding and storage, and improving adhesive force due to anchoring effect.
