Abstract
Description
本発明は賦型シート及びポリエステル化粧板に関する。 The present invention relates to a shaping sheet and a polyester decorative board.
これまでよりポリエステル化粧板は，熱硬化性樹脂化粧板のうちでは，比較的簡単な設備，工程で製造することができ，仕上り外観がよく，一般の化粧板として汎用的な物性を具備していることから，机，キャビネット，厨房設備をはじめとする家具，住設機器などに多く使われている。 From the past, polyester decorative panels can be manufactured with relatively simple equipment and processes among thermosetting resin decorative panels, have a good finished appearance, and have general physical properties as general decorative panels. For this reason, it is often used for furniture such as desks, cabinets, and kitchen facilities, as well as residential equipment.
このポリエステル化粧板は，合板などの板状の基材に無地或は図柄を印刷した化粧紙をポリ酢酸ビニルエマルジョン，或は不飽和ポリエステル樹脂などの接着剤を用いて貼付け，その上に不飽和ポリエステル樹脂を主な成分とする樹脂液を塗布し，しかる後フィルムで被覆してゴムローラーで脱泡し，樹脂液が硬化した後フィルムを除去する方法（フィルム成形法）で得ることができる。 This polyester decorative board is made by applying decorative paper printed with plain or design on a plate-like substrate such as plywood using an adhesive such as polyvinyl acetate emulsion or unsaturated polyester resin, and then unsaturated. It can be obtained by applying a resin liquid containing polyester resin as a main component, then coating with a film, defoaming with a rubber roller, and removing the film after the resin liquid is cured (film molding method).
近年では，表面に凹凸を施し見栄えを向上させるためエンボスフィルムを用いている。このエンボスフィルムは主にＰＥＴフィルムにマット剤を塗布し，塗布面のエンボスロールで凹凸を賦与する方式が採用されている。 In recent years, embossed films have been used to improve the appearance by making the surface uneven. This embossed film employs a system in which a matting agent is mainly applied to a PET film and unevenness is imparted by an embossing roll on the coated surface.
しかしながら，生産ロットが大きく，エンボスロールを製作する必要があることから，小回りがきかない，費用が高額になるといった問題や，また，例えば，住宅の内装材として，水平面にはエンボスメラミン樹脂化粧板を使用し，垂直面には同様のエンボス形状を有するポリエステル化粧板（エンボスポリ板）用いて同調を図ろうとすると，エンボスポリ板の手配に時間と費用を要し，手配が不可能な場合があった。 However, because the production lot is large and it is necessary to produce embossing rolls, there are problems such as small turning and high costs. For example, as an interior material for a house, embossed melamine resin decorative plates are used on the horizontal surface. However, when trying to synchronize using a polyester decorative board (embossed poly board) having the same embossed shape on the vertical surface, it may take time and money to arrange the embossed poly board, and it may not be possible to arrange it. It was.
本発明はかかる課題を解決するべく検討されたもので，簡便な方法で賦型シートを作成することを目的とする発明である。すなわち，プラスチックフィルムの少なくとも片面に，樹脂含浸紙が積層され，更にこの表面に凹凸が形成された賦型材が積層され，熱圧成形後，該賦型材が除去されてなることを特徴とする賦型シートである。 The present invention has been studied to solve this problem, and is an object of the present invention for creating a shaped sheet by a simple method. In other words, the resin film is laminated on at least one side of the plastic film, and a molding material having irregularities formed on the surface is further laminated. After the hot pressing, the molding material is removed. It is a mold sheet.
本発明によれば，簡便な方法で，しかも安価な賦型シートが得られ，エンボスメラミン樹脂化粧板との同調も可能である。 According to the present invention, an inexpensive shaped sheet can be obtained by a simple method and can be synchronized with an embossed melamine resin decorative board.
本発明に用いるプラスチックフィルムの材質は，ポリエチレンテレフタレート（ＰＥＴ），ポリブチレンテレフタレート（ＰＢＴ），ポリエチレンナフタレート，ポリエチレン，ポリプロピレン，セロファン，ジアセチルセルロース，トリアセチルセルロース，アセチルセルロースブチレート，ポリ塩化ビニル，ポリ塩化ビニリデン，ポリビニルアルコール，エチレン−酢酸ビニル共重合体，ポリスチレン，ポリカーボネート，ポリメチルペンテン，ポリスルホン，ポリエーテルエーテルケトン，ポリエーテルスルホン，ポリエーテルイミド，ポリイミド，ナイロン，アクリル樹脂等，いずれも公知のものを用いることができる。とりわけ引っ張り強度，耐熱性に優れ，入手性を考慮すればＰＥＴが好ましい。 The material of the plastic film used in the present invention is polyethylene terephthalate (PET), polybutylene terephthalate (PBT), polyethylene naphthalate, polyethylene, polypropylene, cellophane, diacetyl cellulose, triacetyl cellulose, acetyl cellulose butyrate, polyvinyl chloride, poly Vinylidene chloride, polyvinyl alcohol, ethylene-vinyl acetate copolymer, polystyrene, polycarbonate, polymethylpentene, polysulfone, polyetheretherketone, polyethersulfone, polyetherimide, polyimide, nylon, acrylic resin, etc. are all known. Can be used. In particular, PET is preferable in view of excellent tensile strength and heat resistance, and availability.
樹脂含浸紙としては化粧板用の原紙に熱硬化性樹脂を主な成分とする樹脂液を含浸し，乾燥させたものが使用でき，取り扱い性を考慮して可撓性に優れる薄さの原紙，具体的には１４〜４０ｇ／ｍ２程度の化粧板用の表面紙に，メラミン−ホルムアルデヒド樹脂を数１で示す含浸率（％）で２００〜３００％含浸し，乾燥したものを好適に用いることができる。 As a resin-impregnated paper, a base paper for a decorative board can be used by impregnating a resin liquid containing a thermosetting resin as a main component and drying, and a thin base paper with excellent flexibility in consideration of handleability. , Specifically, the surface paper for decorative board of about 14 to 40 g / m 2 is impregnated with 200 to 300% of melamine-formaldehyde resin at an impregnation ratio (%) expressed by the formula 1, and dried and used preferably. be able to.
凹凸を賦与するための賦型材は型取りできれば特に制約はなく，フィルム状であっても板状であってもよく，エンボスメラミン化粧板を用いると，剛性があり，凹凸が同調して都合がよい。 There are no particular restrictions on the molding material for imparting irregularities, as long as it can be molded, it may be in the form of a film or plate, and the embossed melamine decorative board provides rigidity and is convenient because the irregularities are synchronized. Good.
本発明の賦型シートは，プラスチックフィルムの少なくとも片面に前記の樹脂含浸紙を積層し，更に賦型材を積層した後，１１０〜１５０℃，４〜１０ｋｇｆ／ｃｍ２で熱圧成形することにより得られる。反りを考慮すれば，賦型シートは，樹脂含浸紙−プラスチックフィルム−樹脂含浸紙の積層構造であってもよく，むしろこの方が好ましい。プラスチックフィルムは，ＰＥＴの中でもＡ−ＰＥＴ（アモルファス−ＰＥＴ）が軟化点が低く樹脂含浸紙との熱圧成形時に，熱溶融と熱硬化により強固に接着する。この際Ａ−ＰＥＴの表面にエポキシ−メラミン樹脂系のプライマー処理を施せばより接着が強固になる。 The shaping sheet of the present invention is obtained by laminating the above resin-impregnated paper on at least one side of a plastic film, and further laminating the shaping material, and then hot pressing at 110 to 150 ° C. and 4 to 10 kgf / cm 2. It is done. In consideration of warpage, the shaping sheet may be a laminated structure of resin-impregnated paper-plastic film-resin-impregnated paper, and this is preferable. As for the plastic film, A-PET (amorphous-PET) of PET has a low softening point and is firmly bonded by heat melting and thermosetting at the time of hot pressing with a resin-impregnated paper. At this time, if the surface of A-PET is treated with an epoxy-melamine resin primer, the adhesion becomes stronger.
ポリエステル化粧板の製造は，合板，パーティクルボードなどの基材に化粧紙を接着して熱圧成形し，該化粧紙の表面に不飽和ポリエステル樹脂を主な成分とする樹脂液を塗布し，次いで塗布面を前記賦型シートで被覆し，樹脂が硬化した後に賦型シートを除去することにより得られる。 The polyester decorative board is manufactured by adhering decorative paper to a base material such as plywood or particle board, hot pressing, and applying a resin liquid mainly composed of unsaturated polyester resin on the surface of the decorative paper. It is obtained by covering the coated surface with the above-mentioned shaping sheet and removing the shaping sheet after the resin is cured.
