Abstract

PROBLEM TO BE SOLVED: To provide a decorated cementitious hardened body which ensures a high versatility of design, is excellent in luster and gloss distinctness, and has surface properties following a complicated surface shape.SOLUTION: A metal layer 13 is thermally transferred from a carrier film 20 carrying the metal layer 13 via a release layer 11 to a cementitious hardened body having a surface roughness (Rmax) of ≤10 μm to form a lustrous film having a measured distinctness of gloss value (GD value) of ≥0.5, whereby the objective decorated cementitious hardened body is obtained. When the cementitious hardened body is formed using a form having a flat and smooth surface (a surface roughness of ≤10 μm), a surface roughness (Rmax) of ≤10 μm can be achieved without carrying out surface polishing.

Description

本発明は、加飾されたセメント質硬化体に関し、特に、ホットスタンプにより、加飾されたセメント質硬化体に関する。 The present invention relates to a decorated cementitious cured body, and more particularly to a cemented cured body decorated with a hot stamp.

一般に、物品の表面を転写により加飾する方法としては、ホットスタンプ等が知られている。ホットスタンプは、専用の印刷層が塗られたスタンプ箔の印刷層を熱版により被印刷物に転写して印刷する方法である。例えば、物品表面を被印刷物として、熱版には印刷パターンを凸版として形成し、物品表面と熱版との間に前記スタンプ箔を置き、前記熱版により前記スタンプ箔を物品表面に対し加圧、加熱し、印刷層を物品表面に転写することにより、ホットスタンプを行う。 Generally, a hot stamp or the like is known as a method for decorating the surface of an article by transfer. Hot stamping is a method in which a printing layer of a stamp foil coated with a dedicated printing layer is transferred to a printing material using a hot plate and printed. For example, an article surface is used as a printing material, a printing pattern is formed on a thermal plate as a relief plate, the stamp foil is placed between the article surface and the thermal plate, and the stamp foil is pressed against the article surface by the thermal plate. Heat stamping is performed by heating and transferring the printed layer to the surface of the article.

コンクリート等のセメント質硬化体は、いわゆる打ち放し仕上げでは、素材の灰白色と色の不均一、ざらざら感が素材の質感を醸し出して、ある意味で魅力的である。一方で、内装建材や意匠性の要求される部材に用いるには、不満足とされる向きも否めない。 Hardened cementitious materials such as concrete are attractive in a sense because of the so-called finish finish, the material's grayish white color, uneven color, and graininess create the texture of the material. On the other hand, it cannot be denied that it is unsatisfactory for use as an interior building material or a member that requires design.

そこで、コンクリート等のセメント質硬化体の表面処理に関し、金属溶射皮膜を用いた表面処理により、金属光沢の付与と、溶射による凹部を封孔仕上げする方法が開示されている(特許文献1)。更に、無機質板の表面に加熱発泡剤を混入した接着剤を塗布後、模様を印刷した化粧シートを重ねて凸部を形成したエンボス版を化粧シートに押し当て、凹部を形成しながら立体的な化粧を施す化粧板の製造が開示されている(特許文献2)。 Then, regarding the surface treatment of a cementitious hardened body such as concrete, there is disclosed a method of applying a metallic luster and sealing a recess by thermal spraying by surface treatment using a metal spray coating (Patent Document 1). Furthermore, after applying an adhesive mixed with a heating foaming agent on the surface of the inorganic board, a decorative sheet printed with a pattern is superimposed on the embossed plate formed with a convex part and pressed against the decorative sheet, and a three-dimensional shape is formed while forming a concave part. Production of a decorative board for applying makeup is disclosed (Patent Document 2).

特開平8−269677号公報JP-A-8-269677 特開平7−80995号公報JP-A-7-80995

しかし、特許文献1の加飾方法では、コンクリート等の表面が金属本来の光沢を有し、同時に金属溶射皮膜の封孔処理ができるが、溶射皮膜層の形成が前提となっていた。従って、まず、溶射層を金属溶射によって、形成する必要があり、溶射で可能な金属にかなり限定され、微細な文様の表示等は困難であった。 However, in the decoration method of Patent Document 1, the surface of concrete or the like has the original gloss of metal and can simultaneously seal the metal sprayed coating, but the formation of a sprayed coating layer has been a prerequisite. Therefore, first, it is necessary to form the sprayed layer by metal spraying, which is considerably limited to the metal that can be sprayed, and it is difficult to display fine patterns.

特許文献2では、建材等の仕上げ表面が化粧シートの意匠に凹凸を加えたものであり、比較的厚い接着層と発泡部分の態様を反映したものに限定される傾向にあった。また、エンボス版を用いるため、建材の表面が起伏している場合、この起伏に沿った化粧シートの貼付は困難であった。 In Patent Document 2, the finished surface of a building material or the like has a design of a decorative sheet with irregularities, and tends to be limited to those reflecting a relatively thick adhesive layer and a foamed portion. In addition, since the embossed plate is used, when the surface of the building material is undulated, it is difficult to apply a decorative sheet along the undulation.

そこで、本発明においては、意匠の自由度が高く、光沢性、鮮映性に優れ、複雑な表面形状に沿った表面性状の得られる加飾されたセメント質硬化体を提供することを目的とする。 Therefore, in the present invention, an object of the present invention is to provide a decorated cementitious hardened body that has a high degree of freedom in design, is excellent in glossiness and sharpness, and obtains a surface texture along a complex surface shape. To do.

前記課題を解決するため、セメント質硬化体の表面性状の制御とホットスタンプ方法の制御により、課題解決の糸口を見出し、[1] 表面粗さ(Rmax)が10μm以下であるセメント質硬化体に、金属層を、離型層を介して担持したフィルム層から熱転写して、鮮映性測定値(GD値)0.5以上の光沢膜を形成されたことを特徴とする加飾されたセメント質硬化体を提供する。 In order to solve the above-mentioned problems, the clues for solving the problems are found by controlling the surface properties of the hardened cementitious body and the hot stamping method. [1] In the hardened cementitious body having a surface roughness (Rmax) of 10 μm or less. A decorated cement characterized in that a metallic layer is thermally transferred from a film layer carried via a release layer to form a gloss film having a sharpness measurement value (GD value) of 0.5 or more. A quality hardened body is provided.

さらに、[2]前記硬化体が、表面研磨をすることなく、表面粗さ(Rmax)が10μm以下である硬化体であることを特徴とする[1]記載加飾された加飾されたセメント質硬化体を提供する。 [2] The decorated decorative cement according to [1], wherein the cured body is a cured body having a surface roughness (Rmax) of 10 μm or less without surface polishing. A quality hardened body is provided.

[3]前記金属が、金属蒸着層であることを特徴とする[1]〜[2]記載の加飾されたセメント質硬化体を提供する。
[4]前記セメント質硬化体が、セメント100重量部、粒径2mm以下の細骨材50〜250重量部、減水剤を固形分換算で0.1〜4.0重量部、及び10〜30重量部の水を含む配合物を型枠に流し込んで得た硬化体であることを特徴とする[1]〜[3]記載の加飾されたセメント質硬化体、を提供する。
[3] The decorated cementitious hardened body according to [1] to [2], wherein the metal is a metal vapor deposition layer.
[4] The cementitious hardened body is 100 parts by weight of cement, 50 to 250 parts by weight of fine aggregate having a particle size of 2 mm or less, 0.1 to 4.0 parts by weight of water reducing agent in terms of solid content, and 10 to 30. A decorated cementitious hardened body according to [1] to [3], which is a hardened body obtained by pouring a compound containing parts by weight of water into a mold.

本発明は、表面粗さ(以降、Rmaxと称す)が10μm以下のセメント質硬化体であれば、金属層を、離型層を介して担持したフィルム層から熱転写して、所定の鮮映度が得られる。 In the present invention, in the case of a cementitious hardened body having a surface roughness (hereinafter referred to as Rmax) of 10 μm or less, a metal layer is thermally transferred from a film layer supported via a release layer to obtain a predetermined sharpness. Is obtained.

Rmaxが10μm以下のセメント質硬化体を得るには、モルタルやコンクリート等のセメント質硬化体の表面研磨によって、通常の手段でおこなうことができる。表面研磨手段は、ブラスト処理、金属製研磨剤による研磨、ダイヤモンド研磨、炭化ケイ素粉末研磨等々である。 In order to obtain a cementitious hardened body having an Rmax of 10 μm or less, it can be carried out by ordinary means by surface polishing of a cementitious hardened body such as mortar or concrete. Surface polishing means include blasting, polishing with a metal abrasive, diamond polishing, silicon carbide powder polishing, and the like.

更に、表面研磨後に、または、表面研磨に替えて、セメント質硬化体と熱転写箔の密着性向上のために、プライマリー塗装などの処理を妨げるものではない。こうして、Rmaxが、10μm以下のセメント質硬化体を得ることができる。 Furthermore, after surface polishing or in place of surface polishing, the treatment such as primary coating is not hindered in order to improve the adhesion between the cementitious cured body and the thermal transfer foil. Thus, a cementitious cured body having an Rmax of 10 μm or less can be obtained.

また、表面研磨をせず、Rmaxが10μm以下のセメント質硬化体を得るには、例えば、0打フロー値(「JIS R 5201(セメントの物理試験方法)11.フロー試験」に記載される方法において、15回の落下運動を行わないで測定したフロー値)が230mm以上の高流動モルタル、又はスランプフロー値が50cm以上の高流動コンクリートを、表面が平滑(表面粗さが10μm以下)な型枠を使用して成形すればよい。このような型枠としては、ポリエチレンやポリウレタン製等の樹脂型枠や金属型枠等が挙げられる。 Further, in order to obtain a cementitious hardened body having a Rmax of 10 μm or less without surface polishing, for example, a method described in 0 flow value (“JIS R 5201 (physical test method for cement) 11. flow test”) ), High flow mortar with a flow value of 230 mm or more or high flow concrete with a slump flow value of 50 cm or more, with a smooth surface (surface roughness of 10 μm or less) What is necessary is just to shape | mold using a frame. Examples of such molds include resin molds such as polyethylene and polyurethane, metal molds, and the like.

そして、このセメント質硬化体表面に、熱転写を行えば、その表面がきめ細やかで、高級感のある意匠を実現できる。 And if thermal transfer is performed on the surface of the cementitious cured body, the surface is fine and a high-quality design can be realized.

また、熱転写箔は、後述するように、材質を限定した柔軟なキャリアフィルムで担持された熱転写層を含む。このとき、セメント質硬化体の表面に起伏が形成されていても、滑らかな角のないデザインであって、Rmaxが、10μm以下ならば、この起伏に沿った転写が可能となって、立体的表面を形成し、意匠性が向上する。 Further, the thermal transfer foil includes a thermal transfer layer supported by a flexible carrier film whose material is limited, as will be described later. At this time, even if undulations are formed on the surface of the hardened cementitious material, if the design has no smooth corners and Rmax is 10 μm or less, transfer along the undulations becomes possible, and three-dimensional The surface is formed and the design property is improved.

表面粗さ(Rmax)が10μm以下である前記硬化体に、金属層を、離型層を介して担持したフィルム層から熱転写する。鮮映性測定値(GD値)を、本願の意匠性の判定に用いることは、客観的評価の基準として好ましい。本願においては、このGD値が、0.5以上の光沢膜を形成することができる。 The metal layer is thermally transferred from the film layer supported via the release layer to the cured body having a surface roughness (Rmax) of 10 μm or less. The use of the sharpness measurement value (GD value) for the determination of the design property of the present application is preferable as a criterion for objective evaluation. In the present application, a glossy film having a GD value of 0.5 or more can be formed.

セメント質硬化体への金属層の熱転写を可能にする熱転写箔について、図1に基づき説明する。 A thermal transfer foil that enables thermal transfer of a metal layer to a cementitious hardened body will be described with reference to FIG.

図1は、本発明に用いる熱転写箔の積層構造を模式的に示す図である。熱転写箔100は、キャリアフィルム20の片面に、離型層11、保護着色層12、金属層13、および接着層14が順次積層する。保護着色層12、金属層13、および接着層14は、併せて熱転写層10を構成する。熱転写箔100は、連続テープ状であることが好ましい。 FIG. 1 is a diagram schematically showing a laminated structure of a thermal transfer foil used in the present invention. In the thermal transfer foil 100, the release layer 11, the protective coloring layer 12, the metal layer 13, and the adhesive layer 14 are sequentially laminated on one side of the carrier film 20. The protective coloring layer 12, the metal layer 13, and the adhesive layer 14 together constitute the thermal transfer layer 10. The thermal transfer foil 100 is preferably in the form of a continuous tape.

キャリアフィルム20は、熱転写層10を支持し、熱転写箔100から熱転写層10の転写後は、単独で回収されることが好ましい。キャリアフィルム20としては、転写時のサーマルパッド32からの熱で溶融しないものを選定する。そのため、キャリアフィルム20は、PET(ポリエチレンテレフタレート)、PEN(ポリエチレンナフタレート)、PE(ポリエチレン)が好ましい。例えば、厚みが、12μm〜25μm程度の2軸延伸PETフィルムが用いられる。この材質、厚みならば、セメント質硬化体の表面に起伏が形成されていても、それが、滑らかな角のないデザインであって、Rmaxが、10μmならば、この起伏に沿った転写が可能となって、立体的表面を形成し、意匠性が向上する。 The carrier film 20 supports the thermal transfer layer 10 and is preferably recovered alone after the thermal transfer layer 10 is transferred from the thermal transfer foil 100. As the carrier film 20, a film that is not melted by the heat from the thermal pad 32 during transfer is selected. Therefore, the carrier film 20 is preferably PET (polyethylene terephthalate), PEN (polyethylene naphthalate), or PE (polyethylene). For example, a biaxially stretched PET film having a thickness of about 12 μm to 25 μm is used. With this material and thickness, even if undulations are formed on the surface of the cementitious hardened body, if it is a design without smooth corners and Rmax is 10 μm, transfer along this undulation is possible Thus, a three-dimensional surface is formed, and the design property is improved.

離型層11は、キャリアフィルム20上に形成し、サーマルパッド32で加熱された熱転写層10が、キャリアフィルム20から容易に剥離するために用いることができる。離型層11は、1μm程度の厚みとし、その全部または一部がセメント質硬化体表面に転写移行してもよく、あるいは、セメント質硬化体に全く移行しなくともよい。離型層11は、具体的には、パラフィンワックス、カルナバワックス等のワックス等の樹脂を主成分とすることができる。 The release layer 11 is formed on the carrier film 20 and can be used so that the thermal transfer layer 10 heated by the thermal pad 32 can be easily peeled off from the carrier film 20. The release layer 11 has a thickness of about 1 μm, and all or part of the release layer 11 may be transferred to the cementitious hardened body surface or may not be transferred to the cementitious hardened body at all. Specifically, the release layer 11 can be mainly composed of a resin such as wax such as paraffin wax and carnauba wax.

保護着色層12の厚みは、1μm程度で、熱転写箔製造時、金属層13をキャリアフィルム20に付着させる層である。また加飾、熱転写時には、熱転写層10がキャリアフィルム20から剥がれ、セメント質硬化体に固着し、金属層13を保護するという機能を持つ。着色作用は任意である。保護着色層12の主成分としては、ポリエステル系樹脂、ポリウレタン系樹脂、エチレン−酢酸ビニル共重合体、ポリプロピレン系樹脂、フッ素樹脂などの1種または2種以上を使用できる。フッ素樹脂を用いて、加飾後のセメント質硬化体の耐候性、耐薬品性を高めることもできる。 The thickness of the protective coloring layer 12 is about 1 μm, and is a layer for attaching the metal layer 13 to the carrier film 20 during the production of the thermal transfer foil. Further, at the time of decoration and thermal transfer, the thermal transfer layer 10 is peeled off from the carrier film 20 and fixed to the cementitious hardened body, thereby protecting the metal layer 13. The coloring action is arbitrary. As a main component of the protective coloring layer 12, 1 type (s) or 2 or more types, such as a polyester-type resin, a polyurethane-type resin, an ethylene-vinyl acetate copolymer, a polypropylene-type resin, a fluororesin, can be used. Using a fluororesin, it is possible to improve the weather resistance and chemical resistance of the cemented cured body after decoration.

金属層13は、銅、スズ、アルミニウム、クロム、金、銀等のいずれかの金属を含む。金属層13は、真空蒸着法、スパッタリング法、イオンプレーティング法などの物理蒸着法や、化学蒸着法、電着、化学めっき等により製膜される。より好ましくは、金属層13は真空蒸着法により製膜される。真空蒸着では、高真空炉の中で金属片を蒸発させ、蒸発した金属が金属微粒子となり、保護着色層12に付着する。 The metal layer 13 includes any metal such as copper, tin, aluminum, chromium, gold, silver, and the like. The metal layer 13 is formed by physical vapor deposition such as vacuum vapor deposition, sputtering, or ion plating, chemical vapor deposition, electrodeposition, chemical plating, or the like. More preferably, the metal layer 13 is formed by a vacuum deposition method. In vacuum deposition, a metal piece is evaporated in a high vacuum furnace, and the evaporated metal becomes metal fine particles and adheres to the protective coloring layer 12.

金属層13は、十分な金属光沢を得るために、厚さが20nm以上である。さらに確実に要求される金属光沢を得るために、好適には、厚さが30nm以上である。 The metal layer 13 has a thickness of 20 nm or more in order to obtain a sufficient metallic luster. In order to obtain the required metallic luster more reliably, the thickness is preferably 30 nm or more.

真空蒸着では、真空度、蒸着温度、蒸着処理速度等の蒸着条件を変化させた試料を用いて、電子顕微鏡で金属層形成条件を確認して、真空蒸着条件を調整することができる。 In vacuum deposition, using a sample in which the deposition conditions such as the degree of vacuum, the deposition temperature, and the deposition processing speed are changed, the metal layer formation conditions can be confirmed with an electron microscope, and the vacuum deposition conditions can be adjusted.

接着層14(厚みは2μm程度)は、熱転写箔製造においては、金属層13を保護し、また熱転写時には、金属層13とセメント質硬化体を接着する機能を持つ。材料としては、アクリル系樹脂、ポリエステル系樹脂、ポリアミド系樹脂、ポリウレタン系樹脂、エチレン酢酸ビニル共重合体などの1種または2種以上を主成分とするもの、及び/又は各種ワックスを用いてもよい。 The adhesive layer 14 (having a thickness of about 2 μm) protects the metal layer 13 in the production of the thermal transfer foil, and has a function of adhering the metal layer 13 and the cementitious hardened body during the thermal transfer. As materials, acrylic resin, polyester resin, polyamide resin, polyurethane resin, ethylene vinyl acetate copolymer and the like, and / or various waxes may be used. Good.

図2に示すホットパッドを用いた転写では、台上にセメント質硬化体をセットした。加熱したホットパッドが巻き出した転写箔を硬化体に押し付け、転写箔を加熱しながら加圧し、ホットパッドを離して転写層のみを硬化体表面に残した。転写済みのキャリアは、ロールに巻き取った。 In the transfer using the hot pad shown in FIG. 2, a hardened cementitious material was set on a table. The transfer foil from which the heated hot pad was unwound was pressed against the cured body and pressed while heating the transfer foil, and the hot pad was released to leave only the transfer layer on the surface of the cured body. The transferred carrier was wound up on a roll.

なお、硬化体表面と転写箔の間の空気を吸引する装置(図示せず)を設け、転写箔をホットプレスしながら、クランプ状態で、転写箔と硬化体の間にトラップされる空気を吸引して抜くことにより、転写箔を、硬化体に沿わせて密着させる熱転写を行うこともできる。 A device (not shown) for sucking air between the surface of the cured body and the transfer foil is provided, and air trapped between the transfer foil and the cured body is sucked in a clamped state while hot pressing the transfer foil. Then, thermal transfer can be performed in which the transfer foil is brought into close contact with the cured body.

複雑な表面形状に対応し、意匠の自由度が高いセメント質硬化体への加飾を実現でき、光沢性や鮮映性に極めて優れる加飾されたセメント質硬化体を実現できる。そして、これを利用したセメント二次製品(舗装版、床版等)の意匠性をたかめ、その用途を広範にすることができる。 Corresponding to complex surface shapes, it is possible to realize decorations on hardened cementitious materials with a high degree of design freedom, and it is possible to realize decorated hardened cementitious materials that are extremely excellent in gloss and clarity. And the design property of the cement secondary product (paving slab, floor slab, etc.) using this can be raised, and the use can be broadened.

The embodiment will be described more specifically.
The hardened cementitious material contains 100 parts by weight of fine aggregate having a maximum particle size of 2 mm or less, 0.6 parts by weight of a polycarboxylic acid-based water reducing agent (in terms of solid content), and 20 parts by weight of water with respect to 100 parts by weight of cement. About the compound containing, it confirmed that the zero hit flow value of a compound was 230 mm or more, and it shape | molded using the resin mold whose surface is smooth (surface roughness is 10 micrometers or less). After demolding, a cured mortar having a Rmax of 9 μm was obtained without performing surface polishing.

熱転写箔100の製造に関しては、まず、厚さ10μm程度の2軸延伸PETフィルム等からなるキャリアフィルム20を用意した。 Regarding the manufacture of the thermal transfer foil 100, first, a carrier film 20 made of a biaxially stretched PET film having a thickness of about 10 μm was prepared.

キャリアフィルム20の片面に1μm厚の離型層11を形成した。ワックスを水により溶解した塗工液を用意し、この塗工液をキャリアフィルム20に塗布した後、乾燥することにより行った。保護着色層12は、離型層11にポリエステル樹脂をアルコールにより溶解した塗工液を塗布して形成した。 A release layer 11 having a thickness of 1 μm was formed on one side of the carrier film 20. A coating solution in which wax was dissolved in water was prepared, and this coating solution was applied to the carrier film 20 and then dried. The protective coloring layer 12 was formed by applying a coating solution obtained by dissolving a polyester resin with alcohol to the release layer 11.

ついで、保護着色層12に金属層13を形成した。金属層をアルミニウムとし、金属層13の厚みが70nm以下となる条件で真空蒸着を行った。金属層の厚さが20nm未満では所望の金属光沢感がでにくい。また、金属層13の厚さが70nmより厚いと、表面が乱反射を起こすため光沢がでにくくなるため、金属層の厚みが50nm以下となるような条件で真空蒸着を行うことが好適であった。そこで、40nm厚の金属層を形成した。 Next, a metal layer 13 was formed on the protective coloring layer 12. Vacuum deposition was performed under the condition that the metal layer was aluminum and the thickness of the metal layer 13 was 70 nm or less. If the thickness of the metal layer is less than 20 nm, the desired metallic luster is difficult to achieve. Further, if the thickness of the metal layer 13 is greater than 70 nm, the surface is irregularly reflected and it is difficult to obtain gloss. Therefore, it is preferable to perform vacuum deposition under the condition that the thickness of the metal layer is 50 nm or less. . Therefore, a 40 nm thick metal layer was formed.

次いで、樹脂を有機溶剤に溶解させた塗工液をアルミニウム金属層13に塗布した後、乾燥することにより、接着層14を形成し、本実施形態の熱転写箔100を製造した。 Next, a coating solution in which a resin was dissolved in an organic solvent was applied to the aluminum metal layer 13 and then dried to form an adhesive layer 14, thereby manufacturing the thermal transfer foil 100 of the present embodiment.

さらに、前記モルタル硬化体に熱転写し、加飾されたセメント質硬化体を次のように製造した。図2に示す熱転写装置30は、熱転写箔をスクロールさせる一対の熱転写箔ローラ31と、セメント質硬化体設置台(図示せず)を備えた。一対の熱転写箔ローラ31の中間位置に、熱転写箔100を加熱してセメント質硬化体に熱転写層10を熱転写するためのサーマルパッド32を設けた。図(a)、図(b)は、それぞれ転写前後の作動状態を示した。サーマルパッド32は、ガイド33に沿って上下し、セメント質硬化体を加圧する弾力体であり、セメント質硬化体の起伏する表面形状にフィットした熱転写をおこなった。 Furthermore, the cemented hardened body which was thermally transferred to the mortar hardened body and decorated was manufactured as follows. The thermal transfer device 30 shown in FIG. 2 includes a pair of thermal transfer foil rollers 31 that scroll the thermal transfer foil, and a cementitious hardened body setting table (not shown). A thermal pad 32 for heating the thermal transfer foil 100 to thermally transfer the thermal transfer layer 10 to the cementitious hardened body was provided at an intermediate position between the pair of thermal transfer foil rollers 31. Figures (a) and (b) show the operating states before and after the transfer, respectively. The thermal pad 32 is an elastic body that moves up and down along the guide 33 and pressurizes the cementitious hardened body, and performs thermal transfer that fits the undulating surface shape of the cementitious hardened body.

熱転写時には、熱転写箔ローラ31が回転して熱転写箔100をスクロールさせた。そして、サーマルパッド32が、熱転写箔100を加熱しながら、セメント質硬化体40に圧接させることにより、セメント質硬化体に熱転写層10が熱転写され、加飾セメント質硬化体を製造した。熱転写箔100とセメント質硬化体40の間の空気は、設置台に備えた空気吸引孔(図示せず)より減圧して取り除いた。 During thermal transfer, the thermal transfer foil roller 31 was rotated to scroll the thermal transfer foil 100. The thermal pad 32 was brought into pressure contact with the cementitious cured body 40 while heating the thermal transfer foil 100, whereby the thermal transfer layer 10 was thermally transferred to the cementitious cured body to produce a decorated cementitious cured body. The air between the thermal transfer foil 100 and the hardened cementitious body 40 was removed under reduced pressure from an air suction hole (not shown) provided on the installation base.

得られた加飾されたセメント質硬化体は、鮮映性測定値(GD値)0.5以上の光沢膜が形成され、美麗な外観を有するものであった。 The obtained hardened cementitious body had a beautiful appearance with a gloss film having a sharpness measurement value (GD value) of 0.5 or more.

本発明は、意匠の自由度が高く、光沢性、鮮映性に優れ、起伏のある表面形状に沿った加飾されたセメント質硬化体を提供する等、その用途を広範囲とすることができる。 The present invention has a wide range of uses, such as providing a hardened cementitious body that has a high degree of design freedom, is excellent in glossiness and sharpness, and is decorated along a rough surface shape. .
