Description

本発明は、住宅等の床面、壁面、天井面などの内装に用いられる化粧材に関し、さらに詳しくは、特に住宅等の床面や階段などに用いられる条溝部、面取部を有する化粧材に関するものである。   The present invention relates to a decorative material used for interiors such as a floor surface, a wall surface, and a ceiling surface of a house, and more specifically, a decorative material having a groove portion and a chamfered portion particularly used for a floor surface or a staircase of a house. It is about.

従来、たとえば、1尺×6尺の矩形状の平坦な木質系基材の表面に、小割の突板を寄せ木状に組み付けた絵柄模様を印刷した化粧シートを貼着し、意匠性を向上させて高級感を出すために、絵柄模様の小割の突板同士の接合境界線に沿って木質系基材に底部が位置する横断面形状がV字形状やU字形状等の条溝を切削加工により形成すると共に、条溝の奥行き感を出す目的あるいは条溝の耐水性を向上させる目的で条溝内に透明塗料や着色塗料を塗布した化粧板が床面に貼着される床材として多用されている。   Conventionally, for example, a decorative sheet printed with a design pattern in which a small veneer is assembled in a wooden pattern on the surface of a rectangular flat wooden base material of 1 × 6 scales is attached to improve the design. In order to give a high-class feel, the cross-sectional shape with the bottom located on the wooden base material along the joining boundary line between the small veneers of the pattern is cut into a groove with a V-shaped or U-shaped cross section. It is often used as a flooring material to which a decorative board with a transparent paint or colored paint applied in the groove is stuck to the floor surface for the purpose of increasing the depth of the groove or improving the water resistance of the groove. Has been.

しかし、上記した化粧板は、条溝内に透明塗料や着色塗料を塗布しているために意匠性においては優れるものの、条溝は化粧シートの端面が露出すると共に木質系基材に底部が位置するものであり、耐キャスター性に劣ると共に耐水性においても満足できるものではなく、これらを改善した化粧材が要望されていた。   However, although the decorative board described above is excellent in design because a transparent paint or a colored paint is applied in the groove, the edge of the decorative sheet is exposed and the bottom of the groove is positioned on the wooden substrate. Therefore, the caster is inferior in caster resistance and is not satisfactory in water resistance, and a cosmetic material having improved these has been desired.

そこで、上記要望に応えるものとして、たとえば、化粧シートの絵柄模様の小割の突板同士の接合境界線に対応するように予め切削加工により条溝を表面に設けた木質系基材の表面形状に沿わせて化粧シートをラッピング加工法で加工した化粧材、あるいは、木質系基材の表面に化粧シートを貼着し、その後に化粧シートの絵柄模様の小割の突板同士の接合境界線に対応するように凸部を形成したエンボス版を用いてエンボス加工法で加工して条溝を形成した化粧材が考え出されて市販されている。   Therefore, as a response to the above request, for example, the surface shape of a woody base material in which a groove is provided on the surface by cutting in advance so as to correspond to the joint boundary line between the small protrusions of the decorative pattern of the decorative sheet. A decorative sheet is applied to the surface of a decorative material or a wooden base material that is processed by a lapping method. Thus, a decorative material having a groove formed by embossing using an embossed plate having convex portions has been conceived and marketed.

It is flat and not very satisfactory in terms of design, and it is not satisfactory in terms of design. Like a decorative material provided with grooves by conventional cutting, a colored paint is applied to the grooves to give a sense of depth and improve design. It was necessary to let a sense of quality. However, the work of applying the colored paint to the groove is quite complicated, and this solution has been desired.

そこで本発明は、上記要望に応えるためになされたものであって、条溝への着色塗料の塗布作業を排除することができ、意匠性に優れると共に耐キャスター性や耐水性に優れた化粧材の製造方法を提供することである。   Therefore, the present invention has been made in order to meet the above-mentioned demand, and can eliminate the application work of the colored paint to the groove, and is excellent in design properties and in the caster resistance and water resistance.

Examples of the concavo-convex pattern include a conduit groove provided in a conduit part such as a wood grain pattern, a stone plate surface unevenness, a cloth surface texture, a satin texture, a grain, a hairline, and a striated groove.

また、前記化粧シート3には、化粧材1として使用される用途、たとえば、壁面材、床材、天井材等により要求される物性、特に耐擦傷性、耐摩耗性、耐汚染性等の表面物性に違いはあるものの、通常、前記化粧シート3の最表面に表面保護層が設けられる。この表面保護層を形成する樹脂としては、たとえば、エポキシ系樹脂、アクリル系樹脂、ウレタン系樹脂、アミド系樹脂、エステル系樹脂、あるいは、ポリエチレン,ポリプロピレン,ポリブテン,ポリブタジエン,ポリイソプレン等のポリオレフィンの1種ないしエチレン,プロピレン,ブテン,ブタジエン,イソプレン等のオレフィンの2種以上の共重合体、あるいは、炭素数が4以上のαオレフィンの共重合体(線状低密度ポリエチレン)、エチレン−酢酸ビニル共重合体、エチレン−ビニルアルコール共重合体、あるいは、これらの1種ないしそれ以上からなる混合樹脂等を挙げることができる。そして、この表面保護層の形成方法としては、たとえば、上記樹脂を溶液化するなり、加熱溶融するなりして、グラビア印刷法、ロールコート法、あるいは、押出し塗工法等の周知の塗布手段を適宜用いて塗布することにより形成することができるし、また、上記樹脂をフィルム化してドライラミネーション法等の周知の積層法で積層することにより形成することができる。   Further, the decorative sheet 3 has a physical property required by the application used as the decorative material 1, for example, a wall material, a floor material, a ceiling material, etc., in particular, a surface such as scratch resistance, abrasion resistance, and contamination resistance. Although there is a difference in physical properties, a surface protective layer is usually provided on the outermost surface of the decorative sheet 3. Examples of the resin for forming the surface protective layer include epoxy resins, acrylic resins, urethane resins, amide resins, ester resins, or polyolefins such as polyethylene, polypropylene, polybutene, polybutadiene, and polyisoprene. Copolymers of two or more kinds of olefins such as ethylene, propylene, butene, butadiene, isoprene, etc., or copolymers of α-olefins having 4 or more carbon atoms (linear low density polyethylene), ethylene-vinyl acetate copolymer Examples thereof include a polymer, an ethylene-vinyl alcohol copolymer, or a mixed resin composed of one or more of these. As a method for forming this surface protective layer, for example, the above resin is made into a solution, melted by heating, and a known coating means such as a gravure printing method, a roll coating method, or an extrusion coating method is appropriately used. It can be formed by coating using a resin, or can be formed by forming the resin into a film and laminating by a known laminating method such as a dry lamination method.

また特に、化粧材1が床材として使用される場合にあっては、前記表面保護層を電離放射線硬化型樹脂で形成するのがよい。この理由としては、表面硬度が硬く、かつ、生産性に優れるためである。電離放射線硬化型樹脂とは、電離放射線を照射することにより架橋重合反応を起こし3次元の高分子構造に変化する樹脂である。電離放射線は、電磁波または荷電粒子線のうち分子を重合、架橋し得るエネルギー量子を有するものを意味し、可視光線、紫外線(近紫外線、真空紫外線等)、X線、電子線、イオン線等がある。通常は紫外線や電子線が用いられ、紫外線としては超高圧水銀灯、高圧水銀灯、低圧水銀灯、カーボンアーク灯、ブラックライト蛍光灯、メタルハライドランプ灯の光源が使用できる。紫外線の波長としては、通常1900〜3800Åの波長域が主として用いられる。また、電子線としてはコックロフトワルトン型、バンデクラフト型、共振変圧器型、絶縁コア変圧器型、あるいは、直線型、ダイナミトロン型、高周波型等の各種電子線加速器を用い、100〜1000keV、好ましくは100〜300keVのエネルギーをもつ電子を照射するものを使用できる。   In particular, when the decorative material 1 is used as a flooring, the surface protective layer is preferably formed of an ionizing radiation curable resin. This is because the surface hardness is high and the productivity is excellent. An ionizing radiation curable resin is a resin that undergoes a cross-linking polymerization reaction upon irradiation with ionizing radiation and changes to a three-dimensional polymer structure. Ionizing radiation means an electromagnetic wave or charged particle beam having an energy quantum capable of polymerizing and crosslinking molecules, such as visible light, ultraviolet light (near ultraviolet light, vacuum ultraviolet light, etc.), X-ray, electron beam, ion beam, etc. is there. Usually, ultraviolet rays and electron beams are used. As the ultraviolet rays, light sources such as ultra-high pressure mercury lamps, high pressure mercury lamps, low pressure mercury lamps, carbon arc lamps, black light fluorescent lamps, and metal halide lamps can be used. As a wavelength of ultraviolet rays, a wavelength range of 1900 to 3800 mm is usually used. In addition, as an electron beam, various electron beam accelerators such as a cockroft Walton type, a vandecraft type, a resonant transformer type, an insulated core transformer type, a linear type, a dynamitron type, and a high frequency type are used. Preferably, those that irradiate with electrons having an energy of 100 to 300 keV can be used.

電離放射線硬化型樹脂としては、分子中に、(メタ)アクリロイル基、(メタ)アクリロイルオキシ基等のラジカル重合性不飽和基、又はエポキシ基等のカチオン重合性官能基を有する単量体、プレポリマー又はポリマー(以下、これらを総称して化合物と呼称する)からなる。これら単量体、プレポリマー、及び、ポリマーは単体で用いるか、あるいは、複数種混合して用いる。なお、本明細書で(メタ)アクリレートとは、アクリレート又はメタアクリレートの意味で用いる。   Examples of the ionizing radiation curable resin include a monomer having a radically polymerizable unsaturated group such as (meth) acryloyl group, (meth) acryloyloxy group, or a cationically polymerizable functional group such as epoxy group in the molecule. It consists of a polymer or a polymer (hereinafter collectively referred to as a compound). These monomers, prepolymers, and polymers are used alone or in combination. In this specification, (meth) acrylate is used in the meaning of acrylate or methacrylate.

ラジカル重合性不飽和基を有するプレポリマーとしては、ポリエステル(メタ)アクリレート、ウレタン(メタ)アクリレート、エポキシ(メタ)アクリレート、メラミン(メタ)アクリレート、トリアジン(メタ)アクリレート、ポリビニルピロリドン等が挙げられる。このプレポリマーは、通常、分子量が10000程度以下のものが用いられる。分子量が10000を超えると硬化した樹脂層の耐擦傷性、耐摩耗性、耐薬品性、耐熱性等の表面物性が不足する。上記のアクリレートとメタアクリレートは共用し得るが、電離放射線での架橋硬化速度という点ではアクリレートの方が速いため、高速度、短時間で能率よく硬化させるという目的ではアクリレートの方が有利である。   Examples of the prepolymer having a radical polymerizable unsaturated group include polyester (meth) acrylate, urethane (meth) acrylate, epoxy (meth) acrylate, melamine (meth) acrylate, triazine (meth) acrylate, and polyvinylpyrrolidone. This prepolymer usually has a molecular weight of about 10,000 or less. When the molecular weight exceeds 10,000, the cured resin layer has insufficient surface properties such as scratch resistance, abrasion resistance, chemical resistance, and heat resistance. Although the acrylate and methacrylate can be used in common, the acrylate is more advantageous for the purpose of curing efficiently at a high speed and in a short time because the acrylate is faster in terms of the crosslinking curing rate with ionizing radiation.

また、カチオン重合性官能基を有するプレポリマーとしては、ビスフェノール型エポキシ樹脂、ノボラック型エポキシ樹脂、脂環型エポキシ樹脂等のエポキシ系樹脂、脂肪族系ビニルエーテル、芳香族系ビニルエーテル、ウレタン系ビニルエーテル、エステル系ビニルエーテル等のビニルエーテル系樹脂、環状エーテル化合物、スピロ化合物等のプレポリマーが挙げられる。   Examples of the prepolymer having a cationic polymerizable functional group include epoxy resins such as bisphenol type epoxy resins, novolak type epoxy resins, and alicyclic epoxy resins, aliphatic vinyl ethers, aromatic vinyl ethers, urethane vinyl ethers, and esters. And vinyl ether resins such as vinyl ether, prepolymers such as cyclic ether compounds and spiro compounds.

電離放射線硬化型樹脂は電子線を照射すれば十分に硬化するが、紫外線を照射して硬化させる場合には、増感剤として光重合開始剤を添加することができる。ラジカル重合性不飽和基を有する樹脂系の場合の光重合開始剤としては、アセトフェノン類、ベンゾフェノン類、チオキサントン類、ベンゾイン、ベンゾインメチルエーテル、ミヒラーベンゾイルベンゾエート、ミヒラーケトン、ジフェニルサルファイド、ジベンジルジサルファイド、ジエチルオキサイト、トリフェニルビイミダゾール、イソプロピル−N,N−ジメチルアミノベンゾエート等を単独ないし混合して用いることができる。また、カチオン重合性官能基を有する樹脂系の場合は、芳香族ジアゾニウム塩、芳香族スルホニウム塩、メタロセン化合物、ベンゾインスルホン酸エステル、フリールオキシスルホキソニウムジアリルヨードシル塩等を単独ないし混合物として用いることができる。なお、これら光重合開始剤の添加量は、一般に電離放射線硬化型樹脂100重量部に対して、0.1〜10重量部程度である。また、電離放射線硬化型樹脂で表面保護層を形成する方法としては、たとえば、電離放射線硬化型樹脂を溶液化し、グラビアコート法、ロールコート法等の周知の塗布法で塗布することにより形成することができる。塗布量としては、固形分として概ね5〜30g/m2が適当であり、より好ましくは15〜25g/m2である。 The ionizing radiation curable resin is sufficiently cured when irradiated with an electron beam. However, when it is cured by irradiation with ultraviolet rays, a photopolymerization initiator can be added as a sensitizer. As a photopolymerization initiator in the case of a resin system having a radically polymerizable unsaturated group, acetophenones, benzophenones, thioxanthones, benzoin, benzoin methyl ether, Michler benzoylbenzoate, Michler ketone, diphenyl sulfide, dibenzyl disulfide, Diethyl oxide, triphenylbiimidazole, isopropyl-N, N-dimethylaminobenzoate and the like can be used alone or in combination. In the case of a resin system having a cationically polymerizable functional group, an aromatic diazonium salt, an aromatic sulfonium salt, a metallocene compound, a benzoin sulfonic acid ester, a freeloxysulfoxonium diallyl iodosyl salt, or the like is used alone or as a mixture. be able to. In addition, generally the addition amount of these photoinitiators is about 0.1-10 weight part with respect to 100 weight part of ionizing radiation curable resins. Moreover, as a method of forming a surface protective layer with an ionizing radiation curable resin, for example, it is formed by dissolving an ionizing radiation curable resin and applying it by a known coating method such as a gravure coating method or a roll coating method. Can do. As a coating amount, about 5-30 g / m < 2 > is suitable as solid content, More preferably, it is 15-25 g / m < 2 >.

また、電離放射線硬化型樹脂から形成された表面保護層に、より一層耐擦傷性、耐磨耗性を付与する場合には、粉末状の酸化アルミニウム、炭化珪素、二酸化珪素、チタン酸カルシウム、チタン酸バリウム、マグネシウムパイロボレート、酸化亜鉛、窒化珪素、酸化ジルコニウム、酸化クロム、酸化鉄、窒化硼素、ダイアモンド、金剛砂、ガラス繊維等の研磨材を加えることにより達成することができる。この研磨材の電離放射線硬化型樹脂100重量部に対する割合は1〜80重量部が適当である。   In addition, in the case of further imparting scratch resistance and wear resistance to the surface protective layer formed from the ionizing radiation curable resin, powdered aluminum oxide, silicon carbide, silicon dioxide, calcium titanate, titanium It can be achieved by adding abrasives such as barium acid, magnesium pyroborate, zinc oxide, silicon nitride, zirconium oxide, chromium oxide, iron oxide, boron nitride, diamond, gold sand and glass fiber. The ratio of this abrasive to 100 parts by weight of ionizing radiation curable resin is suitably 1 to 80 parts by weight.

本発明の化粧材1は、従来技術で説明したラッピング加工法やエンボス加工法で容易に製造することができるものである。また、今までは、表面保護層を化粧シート3の最表面に設けることで説明してきたが、表面保護層の形成方法はこれに限るものではなく、ラッピング加工法やエンボス加工法で、まず化粧材1を作製し、その後に前記化粧材1の表面にロールコート法等の周知の塗布方法で塗布して形成してもよいものである。   The decorative material 1 of the present invention can be easily manufactured by the lapping method or the embossing method described in the prior art. Further, until now, the surface protective layer has been described as being provided on the outermost surface of the decorative sheet 3, but the method for forming the surface protective layer is not limited to this. The material 1 may be prepared and then applied to the surface of the decorative material 1 by a known coating method such as a roll coating method.

なお、木質系基材2に化粧シート3を貼着する接着剤としては、化粧シート3の接着剤と当接する面の材質により適宜選択する必要があるが、概ね酢酸ビニル系樹脂、尿素系樹脂、ウレタン系樹脂等の周知も接着剤から選択して用いればよいものである。   It should be noted that the adhesive for adhering the decorative sheet 3 to the woody base material 2 needs to be appropriately selected depending on the material of the surface of the decorative sheet 3 that comes into contact with the adhesive, but is generally a vinyl acetate resin or a urea resin. In addition, well-known urethane resins and the like may be selected from adhesives.
