本発明は■カット加工または折り曲げ加工可能な化粧板
の製造法に関する。DETAILED DESCRIPTION OF THE INVENTION The present invention relates to (1) a method for producing a decorative board that can be cut or bent.
従来よりジアリルフタレートモノマー及び/又は該プレ
ポリマーと不飽和ポリエステルよりなる熱硬化型樹脂を
使用した化粧板はよく知られている。Decorative laminates using thermosetting resins made of diallyl phthalate monomers and/or prepolymers and unsaturated polyesters have been well known.
これらは樹脂を溶剤に溶解させて通常のパターン紙に含
浸もしくは塗布し、これを基材と重ねて熱圧成型法によ
り製造されていた。These were manufactured by dissolving resin in a solvent and impregnating or coating it on ordinary patterned paper, overlapping this with a base material and using a hot pressure molding method.
この方法では含浸紙と基材との積層に際しては熱プレス
を使用するため樹脂分は紙全体に浸透し、得られた化粧
板は性能的には非常に優れているが表面化粧層が可撓性
に乏しいため、これを更に加工して各種の箱物や家具類
を製作する場合においてもその加工方法が著しく制限さ
れていた。This method uses a heat press to laminate the impregnated paper and the base material, so the resin penetrates the entire paper, and the resulting decorative laminate has excellent performance, but the surface decorative layer is flexible. Due to its poor properties, the processing methods used to further process it into various boxes and furniture have been severely limited.
例えばキャビネット類の角、即ち天板と側板との継目や
木端の部分あるいは棚板の木端や木口を処理する場合、
Rを大きくとった所謂Uカット程度のものは従来可能で
あったが、これをより鋭角に仕上げるVカットは不可能
であった。For example, when treating the corners of cabinets, that is, the joints and wood edges between the top and side panels, or the wood edges and wood ends of shelves,
Conventionally, it was possible to make a so-called U-cut with a large radius, but it was not possible to make a V-cut with a more acute angle.
現在のところは軟質ポリ塩化ビニルを用いた化粧板が■
カット可能な実用上唯一のものとされている。At present, decorative boards using soft polyvinyl chloride are available.
It is considered to be the only practical material that can be cut.
しかしながらポリ塩化ビニルは耐熱性、耐溶剤性に乏し
く、また燃焼によって有害なガスを発生するため電化製
品、厨房器具のキャビネット用、化粧用あるいは家具な
どに適用するには好ましくない。However, polyvinyl chloride has poor heat resistance and solvent resistance, and generates harmful gases when burned, so it is not suitable for use in electrical appliances, kitchen appliance cabinets, cosmetics, furniture, and the like.
一方薄葉紙にアミノアルキッド樹脂などを少量塗布して
硬化させた化粧硬化紙を2.5mm厚程度の合板に貼り
合わせたプリント合板は表面化粧硬化紙がエンドレスに
製造でき、又樹脂塗布量も少なく経済的に安価であるの
で多量に生産されている。On the other hand, printed plywood, which is made by applying a small amount of amino alkyd resin to thin paper and curing it, is laminated to plywood of about 2.5 mm thickness.The surface of printed plywood can be produced endlessly, and the amount of resin applied is small, making it economical. It is produced in large quantities because it is inexpensive.
しかしながら、このプリント合板は通常、表面層が坪量
23g/m2程度の薄葉紙に対して樹脂塗布量が15g
/m2程度と非常に少なく、そのために化粧合板の本来
の目的である意匠性が劣り、その他耐水性、耐熱性、硬
度、耐摩耗性にも劣り、又高度な加工性にも耐えられな
いものである。However, this printed plywood usually has a surface layer of thin paper with a basis weight of about 23 g/m2 and a resin coating amount of 15 g.
/ m2, and as a result, the design quality, which is the original purpose of decorative plywood, is inferior, and it is also inferior in water resistance, heat resistance, hardness, and abrasion resistance, and cannot withstand advanced workability. It is.
またこの化粧硬化紙は下地の隠蔽力が小さく、下地の凹
凸がそのまゝ現われるという欠陥があり、所謂目やせと
なって化粧性を低下させ低級品のイメージを免れなかっ
た。Furthermore, this decorative hardened paper had a defect in that the concealing power of the base was low, and the unevenness of the base appeared as it was, resulting in a so-called thinning of the eyes, lowering the cosmetic properties, and giving the paper the image of a low-quality product.
本発明者らは、上記の欠点にかんがみ、意匠性、耐熱性
などの諸性能に優れたジアリルフタレート系樹脂を用い
て表面層が可撓性のある、また経済性に優れたプリント

織布を介して貼り合わせた化粧板は上記欠点がなく所期
の目的に合致した化粧板が得られることを見出し本発明
に至った。In view of the above drawbacks, the present inventors manufactured printed plywood with a flexible surface layer and excellent economic efficiency using diallyl phthalate resin, which has excellent performance such as design and heat resistance. As a result of various studies on methods to do this, we decided to use decorative hardened paper, which is made by applying and hardening a composition containing diallyl phthalate and air-curable unsaturated polyester to thin paper, as the surface layer, and to use soft polyvinyl chloride between the surface layer and the base material. Alternatively, the present inventors have discovered that a decorative board bonded together via a nonwoven fabric can be obtained without the above-mentioned drawbacks and meets the intended purpose.
すなわち、本発明は表面層としてジアリルフタレート類
と空気硬化型不飽和ポリエステルとを含む無溶剤系樹脂
組成物を薄葉紙に対して樹脂分として90〜170重量
%塗布して硬化せしめた硬化紙を使用し、軟質ポリ塩化
ビニルシ一ト又は不織布を介して基材に接着剤を用いて
貼着せしめることを特徴とする■カット加工または折り
曲げ加工可能な化粧板の製造法である。That is, the present invention uses a cured paper in which a solvent-free resin composition containing diallyl phthalates and an air-curable unsaturated polyester is applied to thin paper in an amount of 90 to 170% by weight as a resin content and then cured as a surface layer. (2) A method for producing a decorative board that can be cut or bent, which is characterized in that it is attached to a base material using an adhesive through a soft polyvinyl chloride sheet or nonwoven fabric.
本発明において使用する薄葉紙としては、坪量15〜3
5g/m2のものが適当であり、これには印刷が施され
ていてもよいし、無処理のものでもよい。The thin paper used in the present invention has a basis weight of 15 to 3
A material with a weight of 5 g/m2 is suitable, and may be printed or untreated.
また薄葉紙に対して樹脂の浸透性を調整したり、紙間強
度を上げるためにウレタン樹脂などを塗布するような処
理が施されていてもよい。Further, the thin paper may be subjected to a treatment such as applying a urethane resin or the like to adjust the permeability of the resin or to increase the strength between the sheets.
薄葉紙の坪量が15g/m2未満のものは紙の強度が小
さいため作業性が悪く、又隠蔽力の点においても劣るた
め好ましくない。Thin paper having a basis weight of less than 15 g/m2 is undesirable because the strength of the paper is low, resulting in poor workability and poor hiding power.
又35g/m2をこえるものは樹脂の紙への浸透性が大
きくなり、従って本発明で特定する樹脂量では表面層と
しての性能が充分に得られず可撓性も劣る。If the amount exceeds 35 g/m2, the permeability of the resin into the paper increases, and therefore, with the amount of resin specified in the present invention, sufficient performance as a surface layer cannot be obtained and the flexibility is poor.
また化粧紙の経済性の点でも不利である。It is also disadvantageous in terms of economic efficiency of decorative paper.

き多量の樹脂を塗布して通常の方法で硬化させると大小
無数のシワが発生し、表面化粧紙として到底用いること
ができない。In general, thin paper itself lacks strength, so if a large amount of resin as in the present invention is applied and cured by a conventional method, numerous wrinkles of various sizes will occur, making it impossible to use it as surface decorative paper.

は不織布のみを先に貼り合わせておいて後これを基材と
貼り合わせる方法をとってもよい。In this case, a method may be used in which only the cured paper and the soft polyvinyl chloride sheet or nonwoven fabric are first bonded together, and then this is bonded to the base material.
このようにして得られた化粧板は表面硬くて目やせ現象
はなく、プリント合板用の薄い合板に貼り合わせたもの
でも下地の影響を全く受けず平滑な化粧面が得られる。The decorative laminate thus obtained has a hard surface and does not cause any visual fading, and even when laminated to a thin plywood for printed plywood, a smooth decorative surface can be obtained without being affected by the base material at all.
また加工時の作業性もよく、高速切削、穴あけに際して
も表面層と基材との剥離が起きない。It also has good workability during processing, and the surface layer and base material do not peel off even during high-speed cutting and drilling.
