Description

本発明は床に敷く床用化粧材（床用タイル）に関する。 The present invention relates to a floor decorative material (floor tile) to be laid on the floor.

室内の床の上に敷く床用化粧材として、従来、特許文献１に開示のようなものがある。従来汎用されている床用化粧材としては、塩ビタイルの表面に模様や図柄等を印刷し、その上に樹脂フィルムを貼ったものもある。 Conventionally, as a floor decorative material to be laid on the floor in a room, there is a material as disclosed in Patent Document 1. As a floor decorative material that has been widely used in the past, there is also one in which a pattern or a pattern is printed on the surface of a vinyl chloride tile and a resin film is pasted on the pattern or the pattern.

特許文献１に記載の床用化粧材は、化粧シートの表面に表面樹脂層を、裏面に裏面樹脂層を熱プレスするものであるため、積層加工が面倒であり、専用のマシンを必要とする。また、使用可能材料が耐熱性のあるものに限られる。また、表面樹脂層が剥がれやすい、積層する化粧シートと表面樹脂層と裏面樹脂層の材質や加熱温度によっては化粧シートが歪んだり反ったりする、という課題があった。 The floor decorative material described in Patent Document 1 is one in which a front surface resin layer is heat-pressed on the front surface of a decorative sheet and a back surface resin layer is heat-pressed on the back surface, so that laminating processing is troublesome and a dedicated machine is required. .. In addition, the usable materials are limited to those having heat resistance. Further, there are problems that the surface resin layer is easily peeled off, and the decorative sheet is distorted or warped depending on the materials of the laminated decorative sheet, the front surface resin layer, and the back surface resin layer and the heating temperature.

前記汎用の床用化粧材は、塩ビタイルとその上に貼る樹脂フィルムの収縮率が異なるため、塩ビタイルが歪んだり反ったりする（変形する）ことがあった。貼る前に変形する床に貼りにくくなり、貼った後に変形すると床から剥がれ易くなる、といったことがあった。 In the general-purpose floor decorative material, the vinyl chloride tile and the resin film attached on the vinyl chloride tile have different shrinkage rates, so that the vinyl chloride tile may be distorted or warped (deformed). In some cases, it became difficult to attach it to the floor, which deforms before pasting, and when it deforms after pasting, it easily peels off from the floor.

本発明の課題は、熱プレスを必要とせず、製作が容易であり、反りにくく、剥離しにくい床用化粧材を実現することにある。 An object of the present invention is to realize a floor decorative material which does not require a hot press, is easy to manufacture, is hard to warp, and is hard to peel off.

本発明の床用化粧材は、床に貼る樹脂製の床材、例えば塩ビタイルの表面に印刷（コーティングを含む）により表面膜を、裏面に印刷により裏面膜を設けたものである。塗料は耐摩耗性のある塗料である。表面と裏面の双方に印刷する塗料には同じ性質（特性）のものが使用されている。床材の表面に塗料（インク）により模様或いは色彩が印刷され、その上に透明或いは半透明の塗料が印刷により設けられたものであってもよい。塗料は骨材を混入したものであってもよい。装飾面を床材の表裏両面に設けることもできる。 The floor decorative material of the present invention is a resin floor material to be attached to the floor, for example, a vinyl chloride tile having a front surface film printed (including a coating) on the front surface and a back surface film printed on the back surface. The paint is a wear resistant paint. The paints printed on both the front and back sides have the same properties (characteristics). A pattern or color may be printed on the surface of the floor material by a paint (ink), and a transparent or translucent paint may be provided on the surface by printing. The paint may be a mixture of aggregates. Decorative surfaces can be provided on both the front and back sides of the floor material.

本発明の床用化粧材は次のような効果がある。
１．床材の表裏両面の耐摩耗性の塗料が印刷されて表面膜と裏面膜が設けられているため、フィルムを貼り付ける場合のように加熱する必要がなく、製作が容易である。
２．フィルムを貼り付けたものではないため、剥がれるおそれがない。
３．床材の表裏両面に印刷された塗料が同じ塗料であるため、床材が歪んだり反ったりしにくくなる。このため、床に貼り付けやすく、貼り付け後に剥がれにくくなる床用化粧材となる。
４．骨材を入れた塗料を印刷した場合は耐摩耗性がよくなる。
５．装飾面を床材の表裏両面に設けた場合は、一枚の床材の表面と裏面の装飾面を組み合わせて床に貼って、貼りつけた床の模様に多様性を持たせることができる。 The floor decorative material of the present invention has the following effects.
1. 1. Since the wear-resistant paint on both the front and back surfaces of the floor material is printed to provide the front surface film and the back surface film, it is not necessary to heat the floor material as in the case of pasting the film, and the production is easy.
2. Since it is not a film attached, there is no risk of it peeling off.
3. 3. Since the paint printed on both the front and back sides of the floor material is the same paint, the floor material is less likely to be distorted or warped. Therefore, it is a decorative material for floors that is easy to be attached to the floor and is not easily peeled off after being attached.
4. Abrasion resistance is improved when a paint containing aggregate is printed.
5. When the decorative surfaces are provided on both the front and back surfaces of the floor material, the decorative surfaces on the front surface and the back surface of one floor material can be combined and pasted on the floor to give diversity to the pasted floor pattern.

以下に本発明の床用化粧材の一例を説明する。
［床材］
本発明で使用する床材１は樹脂製であって、床材として使用可能なものであれば、特に制約なく使用可能である。一例としては市販の塩ビタイルがある。市販の塩ビタイルは正方形、長方形といった各種形状である。正方形の場合は５０ｃｍ×５０ｃｍ、４５ｃｍ×４５ｃｍ、３０ｃｍ×３０ｃｍといった各種サイズがある。厚さも各種あり２〜５ｍｍ程度のものが多い。色は表面白色、木目、石柄（石模様）、裏面黒色が一般的である。これらは本発明で使用可能な塩ビタイルの一例であり、本発明ではそれら以外の塩ビタイルであっても使用可能である。 An example of the floor decorative material of the present invention will be described below.
[Floor material]
The floor material 1 used in the present invention is made of resin and can be used without particular limitation as long as it can be used as a floor material. One example is commercially available PVC tiles. Commercially available PVC tiles come in various shapes such as squares and rectangles. In the case of a square, there are various sizes such as 50 cm × 50 cm, 45 cm × 45 cm, and 30 cm × 30 cm. There are various thicknesses, most of which are about 2 to 5 mm. The colors are generally white on the front surface, wood grain, stone pattern (stone pattern), and black on the back surface. These are examples of PVC tiles that can be used in the present invention, and other PVC tiles can also be used in the present invention.

本発明では、床材１の一実施例として表面が白色、裏面が黒色である市販の塩ビタイルを使用し、その表面２に、図１（ａ）、図２（ａ）のように、アクリル又は塩ビ系の塗料（インク）３で模様や着色等の装飾を印刷した装飾膜４を設け、その上に、透明或いは半透明の塗料３を印刷した表面膜５を設け、塩ビタイル１の裏面６に、図１（ｂ）、図２（ｂ）のように、塗料３を印刷した裏面膜７を設けてある。裏面膜７は透明、半透明、不透明のいずれであってもよい。本発明では装飾膜４を裏面６に設けない場合もある。 In the present invention, as an example of the floor material 1, a commercially available vinyl chloride tile having a white front surface and a black back surface is used, and acrylic on the front surface 2 as shown in FIGS. 1 (a) and 2 (a). Alternatively, a decorative film 4 on which decorations such as patterns and colorings are printed with a vinyl chloride paint (ink) 3 is provided, and a surface film 5 on which a transparent or translucent paint 3 is printed is provided on the decorative film 4, and the back surface of the vinyl chloride tile 1 is provided. 6 is provided with a back surface film 7 on which the paint 3 is printed, as shown in FIGS. 1 (b) and 2 (b). Backside layer 7 may be transparent, semitransparent light may be either opaque. In the present invention, the decorative film 4 may not be provided on the back surface 6.

［塗料］
塗料３には塩ビタイル１との親和性に優れた樹脂塗料を使用するのが望ましい。一例としては、ＵＶ硬化型のウレタンアクリレートが適する。装飾膜４、表面膜５、裏面膜７の塗料は同じ性質（機能）の塗料３である。夫々の膜の膜厚は所望厚とすることができるが、いずれも同じ又は略同じにすることができ、装飾膜４をもそれらよりも多少薄くすることもできる。耐摩耗性、滑り止め等の面から、表面膜５の膜厚も裏面膜７の膜厚も共に１０〜１５μｍ程度が望ましい。装飾膜４の上に印刷する表面膜５には透明或いは半透明の塗料３を使用して、下の装飾膜４の装飾が隠れないようにするのが望ましい。表面２、裏面６に塗布する塗料を同じ性質のものとすれば、表裏両面の塗料の伸縮が均等になり、塗料の引っ張りによる床材１の歪み、反りが生じにくくなる。 [paint]
It is desirable to use a resin paint having an excellent affinity with the vinyl chloride tile 1 for the paint 3. As an example, UV curable urethane acrylate is suitable. The paints of the decorative film 4, the front surface film 5, and the back surface film 7 are paints 3 having the same properties (functions). The film thickness of each film can be a desired thickness, but both can be the same or substantially the same, and the decorative film 4 can be made slightly thinner than them. From the viewpoint of wear resistance, non-slip, etc., it is desirable that both the film thickness of the front surface film 5 and the film thickness of the back surface film 7 are about 10 to 15 μm. It is desirable to use a transparent or translucent paint 3 for the surface film 5 printed on the decorative film 4 so that the decoration of the underlying decorative film 4 is not hidden. If the paints applied to the front surface 2 and the back surface 6 have the same properties, the paints on both the front and back surfaces expand and contract evenly, and the floor material 1 is less likely to be distorted or warped due to the pulling of the paints.

塗料３は難燃剤、帯電防止剤、酸化防止剤、紫外線カット剤、吸収剤、その他の機能性剤が含まれたものであってもよい。弾性のある塗料であってもよい。 The paint 3 may contain a flame retardant, an antistatic agent, an antioxidant, an ultraviolet blocking agent, an absorbent, and other functional agents. It may be an elastic paint.

装飾膜４の装飾は、風景画、静物画、動物画、幾何学模様、数字やアルファベット文字等で表現した模様、芝生模様、写真の図柄といった所望の模様とすることができる。単一色或いは二色以上に塗り分けた色模様（着色）であってもよい。装飾膜４は図２（ｂ）のように床材１の裏面にも設けることもできる。この場合は、裏面膜７に透明或いは半透明の塗料３を使用して、裏面の装飾膜４の装飾を裏側から見えるようにして（両面模様付きにして）、床材１の表裏両面のいずれを表にしても貼り付け可能とすることもできる。 The decoration of the decorative film 4 can be a desired pattern such as a landscape painting, a still life painting, an animal painting, a geometric pattern, a pattern expressed by numbers or alphabet letters, a lawn pattern, or a photographic pattern. It may be a single color or a color pattern (coloring) in which two or more colors are painted separately. The decorative film 4 can also be provided on the back surface of the floor material 1 as shown in FIG. 2 (b). In this case, a transparent or translucent paint 3 is used for the back surface film 7 so that the decoration of the back surface decorative film 4 can be seen from the back side (with a double-sided pattern), and either the front or back surface of the floor material 1 can be seen. It is also possible to paste even if it is a table.

［プライマー層］
塩ビタイル１と装飾膜４の間、装飾膜４と表面膜５の間、塩ビタイル１と裏面膜７の間にはプライマー塗料を印刷して、塩ビタイル１と装飾膜４、装飾膜４と表面膜５、塩ビタイル１と裏面膜７の接着を強固にすることもできる。プライマー層には塩ビタイル１の表面２と装飾膜４、装飾膜４と表面膜５、塩ビタイル１の裏面６と裏面膜７との親和性のある塗料３を使用する。 [Primer layer]
Primer paint is printed between the vinyl chloride tile 1 and the decorative film 4, between the decorative film 4 and the front surface film 5, and between the vinyl chloride tile 1 and the back surface film 7, and the vinyl chloride tile 1, the decorative film 4, and the decorative film 4 are printed. It is also possible to strengthen the adhesion between the front surface film 5, the vinyl chloride tile 1 and the back surface film 7. As the primer layer, a paint 3 having an affinity between the front surface 2 and the decorative film 4 of the vinyl chloride tile 1, the decorative film 4 and the front surface film 5, and the back surface 6 and the back surface film 7 of the vinyl chloride tile 1 is used.

［印刷手法］
装飾膜４、表面膜５、裏面膜７、プライマー層は刷毛やローラによる塗布、シルクスクリーン印刷や他の手法による印刷、噴霧器による吹付け、インクジェットプリント、その他、任意の手法で成膜することができる。表面膜５、裏面膜７は一層でも良いが二層以上であってもよい。二層以上にする場合は二層以上が同じ塗料であってもよく、異なる塗料であってもよい。 [Printing method]
The decorative film 4, the front surface film 5, the back surface film 7, and the primer layer can be applied by a brush or a roller, printed by silk screen printing or other methods, sprayed by a sprayer, inkjet printing, or any other method. it can. The front surface film 5 and the back surface film 7 may have one layer, but may have two or more layers. When two or more layers are used, the two or more layers may be the same paint or different paints.

［骨材］
塗料３には骨材８を混入して使用することができる。骨材８は塗料３内で撹拌して混入する。骨材８の入った塗料３を使用して表面膜５を印刷した場合は、図３（ａ）のように骨材８が表面膜５の上まで突出することもあり、図３（ｂ）のように骨材８が表面膜５内に含まれることもある。骨材８は表面膜５内にのみ含まれるようにすることも、装飾膜４内にも含まれるようにすることもできる。必要であれば、裏面膜７内にも、又は裏面膜７と裏面６の装飾膜４との双方にも含ませることができる。表面膜５の表面に突出している場合であっても、突出している骨材８の表面が表面膜５で被覆されるようにすると耐摩耗性が強化され剥離しにくくなる。 [aggregate]
The aggregate 8 can be mixed and used in the paint 3. The aggregate 8 is agitated and mixed in the paint 3. When the surface film 5 is printed using the paint 3 containing the aggregate 8, the aggregate 8 may protrude above the surface film 5 as shown in FIG. 3 (a), and FIG. 3 (b) shows. The aggregate 8 may be contained in the surface film 5 as described above. The aggregate 8 may be contained only in the surface film 5 or may be contained in the decorative film 4. If necessary, it can be contained in the back surface film 7 or both the back surface film 7 and the decorative film 4 on the back surface 6. Even when the surface of the surface film 5 is projected, if the surface of the protruding aggregate 8 is covered with the surface film 5, the wear resistance is enhanced and it becomes difficult to peel off.

骨材８は耐摩耗性、滑り止め性に優れたものが好ましく、例えば、アルミナ粉末、チタン粉末、シリカ粉末、ガラス粉末、その他の粉末が適する。その形状は球状が好ましく、サイズはｎｍ単位或いはμｍ単位の大きさが適する。 The aggregate 8 preferably has excellent wear resistance and non-slip properties, and for example, alumina powder, titanium powder, silica powder, glass powder, and other powders are suitable. The shape is preferably spherical, and the size is preferably in units of nm or μm.

［混合比］
塗料３と骨材８の混合比は任意に設定できるが、一例としては、塗料３との重量比５〜３０％程度が適する。好ましくは１０％である。 [mixing ratio]
The mixing ratio of the paint 3 and the aggregate 8 can be arbitrarily set, but as an example, a weight ratio of about 5 to 30% with the paint 3 is suitable. It is preferably 10%.

本発明の前記実施形態はあくまでも一例であり、塗料の種類、厚さ、骨材の粒径、混合比率等は本発明の目的を達成できる範囲で適宜決定することができる。 The embodiment of the present invention is merely an example, and the type, thickness, particle size of aggregate, mixing ratio, etc. of the coating material can be appropriately determined within a range in which the object of the present invention can be achieved.
