Description
本発明の化粧材は住宅の内外装に用いるものであって、特には建築物の内装用の床タイルなどに用いられる耐摩耗性の優れた化粧材に関する。 The decorative material of the present invention is used for interior and exterior of a house, and particularly relates to a decorative material having excellent wear resistance used for floor tiles for interiors of buildings.
前記用途に用いる化粧材の基材としては、硬度の調整やエンボス加工適性から塩化ビニルシートが用いられていたが、火災時や廃棄後の燃焼時に発生する塩素系ガスの問題があったため、オレフィン系熱可塑性樹脂が用いられるようになってきた。 As the base material of the cosmetic material used for the above-mentioned use, a vinyl chloride sheet was used from the viewpoint of hardness adjustment and embossing suitability. However, there was a problem of chlorine-based gas generated at the time of fire or combustion after disposal. Thermoplastic resins have been used.
しかしながら、このオレフィン系熱可塑性樹脂基材上に絵柄模様をグラビア印刷などによって設け、表面側に異なる樹脂系からなる透明熱可塑性樹脂層を設けた場合に、層間強度が十分に発現できず、層間剥離の問題があった。 However, when a pattern is provided on the olefinic thermoplastic resin substrate by gravure printing or the like, and a transparent thermoplastic resin layer made of a different resin system is provided on the surface side, the interlayer strength cannot be sufficiently exhibited, There was a problem of peeling.
しかし、透明熱可塑性樹脂層にオレフィン系熱可塑性樹脂基材と同系の樹脂を用いると、表面の耐磨耗性（磨耗Ｂ試験 研磨紙Ｓ−４２）が低下するという問題があった。 However, when a resin similar to the olefinic thermoplastic resin substrate is used for the transparent thermoplastic resin layer, there is a problem that the surface wear resistance (wear B test abrasive paper S-42) is lowered.
本発明は、従来の技術における上記の如き問題点に鑑みてなされたものであり、その目的とするところは、各種物性面において従来のポリ塩化ビニル樹脂製の化粧材と同等の性能を有しつつ、燃焼時の有害物質発生の問題がなく、床用途の要求物性の一つである耐摩耗性（磨耗Ｂ試験 研磨紙Ｓ−４２）を有する化粧材を提供することにある。 The present invention has been made in view of the above-described problems in the prior art, and its object is to have performance equivalent to that of a conventional decorative material made of polyvinyl chloride resin in terms of various physical properties. On the other hand, it is an object of the present invention to provide a cosmetic material that has no problem of generation of harmful substances during combustion and has abrasion resistance (wear B test abrasive paper S-42), which is one of the required physical properties for floor use.
本発明はこの課題を解決したものであり、すなわち請求項１記載の発明は、オレフィン系熱可塑性樹脂基材上に絵柄模様層と透明熱可塑性樹脂層とを少なくとも設けてなる化粧材において、前記透明熱可塑性樹脂層がアイオノマー樹脂層とエチレン−メタクリル酸共重合体層の２層の組み合わせであり総厚が３５０〜４００μｍであることを特徴とする化粧材である。 The present invention solves this problem, that is, the invention described in claim 1 is a cosmetic material comprising at least a pattern layer and a transparent thermoplastic resin layer on an olefinic thermoplastic resin substrate. The transparent thermoplastic resin layer is a combination of two layers of an ionomer resin layer and an ethylene-methacrylic acid copolymer layer, and has a total thickness of 350 to 400 μm.
本発明はその請求項１記載の発明により、透明熱可塑性樹脂層がアイオノマー樹脂層とエチレン−メタクリル酸共重合体層の２層の組み合わせであり総厚が３５０〜４００μｍとすることで、層間強度と表面の耐摩耗性の両方に優れた化粧材とすることが可能となった。 According to the present invention, the transparent thermoplastic resin layer is a combination of two layers of an ionomer resin layer and an ethylene-methacrylic acid copolymer layer, and the total thickness is 350 to 400 μm. And a decorative material excellent in both surface wear resistance.
以下本発明を図面に基づき詳細に説明する。図１に本発明の化粧材の一実施例の断面の構造を示す。オレフィン系熱可塑性樹脂基材１上に絵柄模様層２、アイオノマー樹脂層３、エチレン−メタクリル酸共重合体層４を積層してなる。 Hereinafter, the present invention will be described in detail with reference to the drawings. FIG. 1 shows a cross-sectional structure of one embodiment of the decorative material of the present invention. The pattern pattern layer 2, the ionomer resin layer 3, and the ethylene-methacrylic acid copolymer layer 4 are laminated on the olefin-based thermoplastic resin substrate 1.
本発明におけるオレフィン系熱可塑性樹脂基材１としては、従来公知のオレフィン系樹脂フィルムが使用可能であり、具体的にはポリエチレン、ポリプロピレン（ホモあるいはランダム、共重合）等が使用可能である。層厚としては２０〜２００μｍ程度が好適である。 As the olefinic thermoplastic resin substrate 1 in the present invention, a conventionally known olefinic resin film can be used, and specifically, polyethylene, polypropylene (homo, random, copolymer) or the like can be used. The layer thickness is preferably about 20 to 200 μm.
本発明における絵柄模様層２としては、絵柄を形成するのはインキであり、顔料およびバインダーは適宜選定すればよい。フィルムとの接着性を考慮し、適宜原材料を選定すればよい。例えば、イソシアネート硬化剤と活性水素を有したバインダーを混合させた塗工液が、接着性の点では優位である。絵柄模様層を施す方法は、従来から行われているグラビア印刷が好適であるが、スクリーン印刷、オフセット印刷、グラビアオフセット印刷、フレキソ印刷などとくに印刷手法は問わない。 As the pattern layer 2 in the present invention, it is ink that forms the pattern, and the pigment and the binder may be appropriately selected. A raw material may be appropriately selected in consideration of adhesiveness with the film. For example, a coating liquid in which an isocyanate curing agent and a binder having active hydrogen are mixed is superior in terms of adhesiveness. Conventionally, the gravure printing performed conventionally is suitable for the method of applying the pattern pattern layer, but the printing method is not particularly limited, such as screen printing, offset printing, gravure offset printing, flexographic printing.
本発明におけるアイオノマー樹脂層３としては、アイオノマー樹脂は一般に有機及び無機の成分が共有結合とイオン結合によって結合されている樹脂のことである。本発明に特に好ましく使用されるアイオノマー樹脂としては、共重合体の分子間を金属イオンで架橋した樹脂が挙げられ、この場合の共重合体としてはアクリレート系共重合体、例えばエチレン−メタクリル酸共重合体などが挙げられる。金属イオンとしては、例えばＮａ、Ｋ、Ｍｇ、Ｚｎ等のイオンが挙げられる。 As the ionomer resin layer 3 in the present invention, the ionomer resin is generally a resin in which organic and inorganic components are bonded by a covalent bond and an ionic bond. Examples of the ionomer resin that is particularly preferably used in the present invention include resins in which the intermolecular molecules of the copolymer are cross-linked with metal ions. In this case, the copolymer includes an acrylate copolymer such as an ethylene-methacrylic acid copolymer. A polymer etc. are mentioned. Examples of metal ions include ions such as Na, K, Mg, and Zn.
アイオノマー樹脂を得るには、例えば、カルボキシル基を側鎖に有する単量体（たとえばアクリル酸）を共重合させたエチレン系のポリマーにＮａ、Ｋ、Ｍｇ、Ｚｎなどの水酸化物、アルコレート、低級脂肪酸塩などを加えて酸基を中和する方法が挙げられる。これにより、分子鎖に沿って分布するカルボキシル陰イオンが分子間に存在する金属陽イオンと静電的に結合して一種の架橋を形成し、共重合体の分子間を金属イオンで架橋した構造のアイオノマー樹脂が得られる。 In order to obtain an ionomer resin, for example, an ethylene polymer obtained by copolymerizing a monomer having a carboxyl group in a side chain (for example, acrylic acid), a hydroxide such as Na, K, Mg, Zn, alcoholate, The method of neutralizing an acid group by adding a lower fatty acid salt etc. is mentioned. As a result, a structure in which carboxyl anions distributed along the molecular chain are electrostatically combined with metal cations existing between the molecules to form a kind of cross-links, and the copolymer molecules are cross-linked with metal ions. The ionomer resin can be obtained.
本発明に好ましく使用されるアイオノマー樹脂は、上述の共重合体樹脂であるため、その共重合組成によってシートの硬さが任意に選択でき、また金属イオンによる架橋結合は加熱により結合力が弱められ、冷却すると結合力が回復するという塩化ビニル樹脂等の熱可塑性樹脂と似た性質を有するので、熱ラミネーション及びエンボス加工により製造されていた例えば従来の塩化ビニル製の化粧材の製造ライン等に適用しやすいという利点がある。 Since the ionomer resin preferably used in the present invention is the above-described copolymer resin, the hardness of the sheet can be arbitrarily selected depending on the copolymer composition, and the cross-linking bond by metal ions is weakened by heating. Since it has properties similar to those of thermoplastic resins such as vinyl chloride resin, the bonding strength recovers when cooled, so it can be applied to, for example, conventional production lines for vinyl chloride cosmetics that were manufactured by thermal lamination and embossing. There is an advantage that it is easy to do.
本発明におけるエチレン−メタクリル酸共重合体層４としては、メタクリル酸の含有率が４〜１５重量％の範囲にあるものが好適に使用され、前記アイオノマー樹脂層３などと良く調和し、比較的硬質で、表面光沢、耐汚れ性、耐傷性、耐凹み性などの改善に有効に作用する。メタクリル酸の含有率が１５重量％より多いと脆すぎ、硬すぎ、成形しにくいので、耐傷性、滑り性などの改善が不充分となり、メタクリル酸の含有率が４重量％より少ないとその性質が低密度ポリエチレンによく似ているため、床用としての耐傷性、耐凹み性などの改善が不充分となる。
As the ethylene-methacrylic acid copolymer layer 4 in the present invention, those having a methacrylic acid content in the range of 4 to 15% by weight are preferably used, which is in good harmony with the ionomer resin layer 3 and the like. Hard and effective in improving surface gloss, dirt resistance, scratch resistance, and dent resistance. If the content of methacrylic acid is more than 15% by weight, it is too brittle, too hard, and difficult to mold. Therefore, the scratch resistance and slipping properties are insufficiently improved. Is very similar to low-density polyethylene, so improvement in scratch resistance, dent resistance, etc. for flooring is insufficient.
オレフィン系熱可塑性樹脂基材１として厚さ７０μｍのランダムポリプロピレン樹脂クリアフィルム（リケンテクノス（株）製「リベストＴＰＯ」）を用い、この一面に絵柄模様層２としてグラビア印刷により木目柄を印刷した。
一方、アイオノマー樹脂層３として厚さ２００μｍの「ハイミラン」（三井デュポンポリケミカル(株)製）を用い、エチレン−メタクリル酸共重合体層４として厚さ１８０μｍの「ニュクレル」（三井デュポンケミカル（株）製）を用い、これらを共押出しにて貼り合せ、透明熱可塑性樹脂層とした。
その後、前記オレフィン系熱可塑性樹脂基材１の絵柄模様層２を設けた面と、前記透明熱可塑性樹脂層のアイオノマー樹脂層３側とを、ラミネート温度１２０℃の条件で連続ラミネーション方式により積層して貼り合わせると同時に、前記エチレン−メタクリル酸共重合体層４側の表面にエンボスロールをラミネート温度と同じ１２０℃で加圧してエンボスを施し、凹凸模様を付与し、化粧材を作製した。
A random polypropylene resin clear film (“Rivest TPO” manufactured by Riken Technos Co., Ltd.) having a thickness of 70 μm was used as the olefin-based thermoplastic resin substrate 1, and a wood grain pattern was printed as a pattern pattern layer 2 on the one surface by gravure printing.
On the other hand, “Himiran” (made by Mitsui DuPont Polychemical Co., Ltd.) having a thickness of 200 μm was used as the ionomer resin layer 3, and “Nuclele” (Mitsui DuPont Chemical Co., Ltd.) having a thickness of 180 μm was used as the ethylene-methacrylic acid copolymer layer 4. These were bonded together by coextrusion to obtain a transparent thermoplastic resin layer.
Thereafter, the surface of the olefinic thermoplastic resin substrate 1 on which the pattern layer 2 is provided and the ionomer resin layer 3 side of the transparent thermoplastic resin layer are laminated by a continuous lamination method at a lamination temperature of 120 ° C. At the same time, the embossing roll was pressed on the surface on the ethylene-methacrylic acid copolymer layer 4 side at 120 ° C., which is the same as the laminating temperature, to give an uneven pattern, and a decorative material was prepared.
