Definitions
- the present invention relates to a printed resin film for decorative laminate and a decorative plate on which the resin film is laminated, and more particularly, to a home electric appliance such as a door of an electric refrigerator and an air conditioner cover.
- Resin film for decorative board lamination and its application which are particularly suitable for applications requiring aesthetic design, such as exterior products, steel furniture, furniture, and interiors of buildings, etc.
- a decorative film in which a resin layer serving as a base material is printed using a normal method, and a coating layer such as an amino alkyd resin or a urethane resin is provided to protect the surface of the printed layer.
- a decorative film such as a transparent polyvinyl chloride film and a decorative film laminated with a biaxially oriented polyester film, and apply an adhesive. It is also known to be laminated on a substrate such as a zinc-plated steel plate, plywood, or MDF.
- the decorative board laminated with the decorative film of the above (1) has insufficient strength of the decorative film ir, so when applying V-cut processing, etc., the decorative film may break during processing, or the ink in the corners may be damaged. There is a problem of easy peeling.
- the decorative board laminated with the decorative film of (2) has excellent surface properties such as stain resistance and solvent resistance, but the surface film has poor flexibility and has a high softening temperature, so when embossing is performed, Embossing is difficult.
- the decorative board laminated with the decorative film of (3) is made of polyvinyl chloride film, so its surface properties such as stain resistance and solvent resistance are inferior. Poisonous gas such as hydrogen gas and harmful substances resulting from it generate pollutants for the environment and damage the incinerator when incinerated.
- An object of the present invention is to solve the above-mentioned problem by providing a picture pattern formed by wiving printing, which is superior in design to a decorative sheet using a conventional polyvinyl chloride resin ID film and has an excellent design property. It is another object of the present invention to provide a printed resin film for decorative laminates having excellent surface properties such as stain resistance and solvent resistance, and a decorative laminate obtained by laminating the resin film.

(耐水劣化性） (Water resistance)
本発明の化粧板を高温多湿の状態で長時間経時させた場合 （例えばュニットバ スの内装材として用いた場合など） を想定し、 長時間水と接した場合の樹脂フィ ルムの耐水劣化性をデュポン衝撃試験法で評価した。 Assuming that the decorative board of the present invention is aged for a long time in a high temperature and high humidity state (for example, when used as an interior material of a unit bath), the water resistance of the resin film when exposed to water for a long time is evaluated. It was evaluated by the DuPont impact test method.
実施例 1、 2および 3で作成した化粧板積層用印刷樹脂フィルムを、 厚さ 0. 5 mmの亜鉛めつき鋼板に積層し試験片とした。 この試験片を 6 OmmX 6 Om mの大きさに切り出し、 38 ± 2°Cの温度に保持された脱塩水中に 1力月間浸漬 した後室温で乾燥し、 デュポン衝撃試験機を用い、 J I S K 5400に準拠し \0 た条件 （衝撃部の大きさ lZ2inch*、 重さ l k g、 落下高さ 5 O cm) で衝撃 を負荷した。 衝撃を負荷した後の樹脂フィルムの状態を肉眼観察し、 下記の 5段 階で評価した。 The printed resin film for decorative laminate lamination prepared in Examples 1, 2 and 3 was laminated on a zinc-plated steel plate having a thickness of 0.5 mm to obtain a test piece. This test piece was cut into a size of 6 OmmX 6 Omm, immersed in demineralized water maintained at a temperature of 38 ± 2 ° C for one month, dried at room temperature, and subjected to JISK 5400 using a Dupont impact tester. The impact was applied under the conditions (size of impact part lZ2inch *, weight lkg, drop height 5 O cm) according to. The state of the resin film after the impact was applied was visually observed and evaluated in the following five stages.
◎：樹脂フィルムに割れが認められない。 ：: No crack was observed in the resin film.
〇：樹脂フィルムの一部に細かい割れが認められる。 〇: Fine cracks are observed in a part of the resin film.
△：樹脂フィルムのエンボス加工部全体に細かい割れが認められる。 Δ: Fine cracks are observed in the entire embossed portion of the resin film.
X ：樹脂フィルムのエンボス加工部全体に大きな割れが認められる。 X: A large crack is observed in the entire embossed portion of the resin film.
X X ：樹脂フィルム全体に割れが著しい。 X X: The entire resin film is significantly cracked.
上記の評点において、 ◎および〇は使用上の問題はない。 なお、 この試験は 10 枚の試験片について実施した。 これらの化粧板の特性評価を下記に示す。 In the above scores, ◎ and Δ have no problem in use. This test was performed on 10 test pieces. The characteristics of these decorative boards are shown below.
0 表 1 0 Table 1
本発明の化粧板積層用印刷樹脂フィルムは上記のように構成されており、 ボリ I) ブチレンテレフ夕レートフィルムからなる基材樹脂層および着色樹脂層が熱や張 力に対する伸縮変動が少なく、 優れた寸法安定性を有しているため、 印刷見当精 度のよい印刷物を得ることが出来る。 さらに、 エンボス加工性に優れるため、 鮮 明なワイピング印刷が可能である。 The printed resin film for decorative laminate lamination of the present invention is constituted as described above, and is excellent in that the base resin layer and the colored resin layer composed of the polybutylene terephthalate film have little fluctuation in expansion and contraction due to heat and tension. Because of its dimensional stability, it is possible to obtain printed matter with good print registration accuracy. Furthermore, clear wiping printing is possible due to its excellent embossability.
また、 従来のボリ塩化ビニル樹脂フィルムと同様の製造方法および製造条件で | P 化粧フィルムが得られるために、 新規設備の増設や設備の改造などの設備投資を 必要とせず、 従来のポリ塩化ビニル樹脂フィルムと同様の、 印刷柄とエンボス柄 が同調した意匠性に優れた絵柄模様を表現することができる。 In addition, since the decorative film can be obtained under the same manufacturing method and manufacturing conditions as the conventional polyvinyl chloride resin film, capital investment such as expansion of new facilities or remodeling of facilities is not required. As with resin films, it is possible to express a design with excellent design, in which the printed pattern and the embossed pattern are synchronized.
さらに、 基材樹脂層や表面保護層を構成する樹脂中に可塑剤を含有していない ために、 可塑剤のブリードによる表面汚染などの問題が生じることなく、 耐汚染 iir 性、 耐溶剤性、 耐水性などの表面物性に優れている。 Furthermore, since the resin constituting the base resin layer and the surface protective layer does not contain a plasticizer, problems such as surface contamination due to bleeding of the plasticizer do not occur, and contamination resistance iir resistance, solvent resistance, Excellent surface properties such as water resistance.
またさらに、 焼却廃棄する際に、 塩化水素ガスのような有毒ガスの発生がない ため、 環境を汚染する心配もなく環境保全性においても優れている。
In addition, no toxic gas such as hydrogen chloride gas is generated during incineration and disposal, so there is no need to worry about environmental pollution and excellent environmental conservation.
