Description
本発明は、建築物内外壁や土木構築物等の表面化粧に適用可能な装飾面の形成方法に関するものである。 The present invention relates to a method for forming a decorative surface that can be applied to surface decorations such as inner and outer walls of buildings and civil engineering structures.
従来、建築物内外壁や土木構築物等の表面に対し、石材調、天然石調、砂岩調等の自然の風合いを表出できる模様は、例えば、意匠材を塗装することによって付与されている。
このような装飾面の模様は、凹凸感、陰影感もあり、個性的で高級感溢れる模様として一般的に知られており、このような模様を得る方法が、種々提案されている（例えば、特許文献１、２等）。
Conventionally, a pattern capable of expressing a natural texture such as a stone tone, a natural stone tone, a sandstone tone, or the like is given to a surface of a building inner / outer wall or a civil engineering structure by, for example, painting a design material.
Such a decorative surface pattern is also generally known as a unique and high-quality pattern with unevenness and shading, and various methods for obtaining such a pattern have been proposed (for example, Patent Documents 1 and 2).
特許文献１には、着色塗料、有色骨材、天然石粒を含む被覆組成物が記載されているが、このような組成物の工夫のみでは、すぐれた意匠性を表出するには限度がある。また、有色骨材、天然石粒による凹凸感、陰影感が強調され、かえって敬遠される場合がある。 Patent Document 1 describes a coating composition containing a colored paint, colored aggregate, and natural stone particles, but there is a limit to exhibiting excellent design properties only with such a composition. . Also, the unevenness and shading caused by colored aggregates and natural stone grains are emphasized and may be avoided.
特許文献２は、刷毛類を用いて筋目をつける方法が記載されているが、優れた意匠性を表出するには、熟練の施工技術が必要となり、好ましい方法とはいえない。また、刷毛による筋が人工的となり、自然の風合いを表出できない場合もある。 Patent Document 2 describes a method of scoring using brushes, but in order to express excellent design properties, a skilled construction technique is required, which is not a preferable method. In addition, there are cases where the brush streaks become artificial and cannot express a natural texture.
本発明者は、新たな意匠性の創造を目指して鋭意検討を行った結果、異なる色相の意匠材が混在する装飾面に対し、特定のローラーを押し当てて転動させることにより、落ち着きのある自然の風合いを有する新たな意匠を表出することに成功し、本発明を完成するに至った。 As a result of intensive studies aimed at creating a new design, the present inventor is calm by pressing a specific roller against a decorative surface in which design materials of different hues are mixed. It succeeded in expressing the new design which has a natural texture, and came to complete this invention.
すなわち、本発明は以下の特徴を有するものである。
１．（１）基材に対し、
結合材、意匠骨材を含む意匠材（Ｐ）と、
結合材、意匠骨材を含み、該意匠材（Ｐ）と色相の異なる意匠材（Ｑ）とを、
意匠材（Ｐ）の色相と意匠材（Ｑ）の色相が混在するように塗装し、
（２）前記工程（１）で塗装された意匠材（Ｐ）と意匠材（Ｑ）が混在する意匠面に対し、意匠材（Ｐ）と意匠材（Ｑ）が乾燥する前に、繊維質層の厚さが１０ｍｍ以下である繊維質ローラーを押し当てて転動させることを特徴とする装飾面の形成方法。
２．（１）（１‐１）基材に対し、結合材、意匠骨材を含む意匠材（Ｐ）を塗装した後、
（１‐２）該意匠材（Ｐ）が乾燥する前に、結合材、意匠骨材を含み、意匠材（Ｐ）と色相の異なる意匠材（Ｑ）を部分塗装し、
（２）前記工程（１）で塗装された意匠材（Ｐ）と意匠材（Ｑ）が混在する意匠面に対し、意匠材（Ｐ）と意匠材（Ｑ）が乾燥する前に、繊維質層の厚さが１０ｍｍ以下である繊維質ローラーを押し当てて転動させることを特徴とする装飾面の形成方法。
３．前記工程（２）において、意匠材（Ｐ）と意匠材（Ｑ）が混在する意匠面に対し、意匠材（Ｐ）と意匠材（Ｑ）が乾燥する前に、水及び／または溶剤を含む繊維質層の厚さが１０ｍｍ以下である繊維質ローラーを押し当てて転動させることを特徴とする１．または２．に記載の装飾面の形成方法。

The design surface (I) may be formed by coating the design material (P) and the design material (Q) in a ball shape. Although it does not specifically limit as a coating method, For example, the method of coating a design material (P) and a design material (Q) simultaneously using a double-headed gun (multi-headed gun), a double-headed spray (multi-headed spray), an air spray gun, For example, an airless spray gun, a ricin gun, a stucco gun, or the like is appropriately selected, and a design material (P) and a design material (Q) are respectively coated.

In addition, prior to the coating in the step (1), the base material surface may be preliminarily applied with any undercoat material, intermediate coating material, or base coating material.
上記（ＩＩ）の意匠面は、意匠材（Ｐ）を塗装し、連続的な塗装面を形成した後、意匠材（Ｑ）を不連続な玉状に塗装することで得られる。例えば、
（１‐１）基材に対し、結合材、意匠骨材を含む意匠材（Ｐ）を塗装した後、
（１‐２）該意匠材（Ｐ）が乾燥する前に、結合材、意匠骨材を含み、意匠材（Ｐ）と色相の異なる意匠材（Ｑ）を部分塗装する方法等が挙げられる。
The design surface of (II) is obtained by coating the design material (P) to form a continuous coating surface, and then coating the design material (Q) in a discontinuous ball shape. For example,
(1-1) After coating the design material (P) including the binder and the design aggregate on the base material,
(1-2) Before the design material (P) is dried, a method of partially coating the design material (Q) including the binder and the design aggregate and having a hue different from that of the design material (P) may be used.
このような方法では、まず、（１‐１）基材に対し、意匠材（Ｐ）を塗装する（工程（１‐１））。
工程（１‐１）では、意匠材（Ｐ）の塗装方法は特に限定されず、鏝、スプレー、ガン、ローラー、刷毛等の公知の塗装器具を用いて塗装すればよい。また、１回、または、２回以上の複数回で塗装すればよい。
塗付け量としては、特に限定されないが、意匠材（Ｐ）は、０．５ｋｇ／ｍ２以上１０ｋｇ／ｍ２以下で塗装することが好ましく、１ｋｇ／ｍ２以上８ｋｇ／ｍ２以下で塗装することがより好ましい。
In such a method, first, (1-1) the design material (P) is applied to the base material (step (1-1)).
In the step (1-1), the method for applying the design material (P) is not particularly limited, and the design material (P) may be applied using a known application tool such as a scissors, a spray, a gun, a roller, and a brush. Moreover, what is necessary is just to paint by 1 time or multiple times of 2 times or more.
The coating amount is not particularly limited, but the design material (P) is preferably applied at 0.5 kg / m 2 or more and 10 kg / m 2 or less, and is preferably applied at 1 kg / m 2 or more and 8 kg / m 2 or less. It is more preferable.
次に、意匠材（Ｐ）を塗装した後、意匠材（Ｐ）が乾燥する前に、意匠材（Ｑ）を部分塗装する（工程（１‐２））。
工程（１‐２）では、意匠材（Ｑ）の塗装方法は特に限定されないが、意匠材（Ｐ）面に対し、鏝、スプレー、ガン、ローラー、刷毛等を用いて部分塗装することができ、好ましくはエアーガン、エアレススプレーガン等を用いて意匠材（Ｑ）を玉状に吹き付ける方法等が挙げられる。また、意匠材（Ｑ）は、その色相が視認できる程度に部分塗装すればよく、１回、または、２回以上の複数回で塗装することもできる。
塗付け量としては、特に限定されないが、意匠材（Ｑ）は、０．１ｋｇ／ｍ２以上１．４ｋｇ／ｍ２以下で塗装することが好ましく、０．２ｋｇ／ｍ２以上０．７ｋｇ／ｍ２以下で塗装することがより好ましい。
Next, after the design material (P) is applied, the design material (Q) is partially applied before the design material (P) is dried (step (1-2)).
In step (1-2), the design method of the design material (Q) is not particularly limited, but the design material (P) surface can be partially coated with a scissors, spray, gun, roller, brush, etc. Preferably, a method of spraying the design material (Q) in a ball shape using an air gun, an airless spray gun or the like can be used. In addition, the design material (Q) may be partially coated to such an extent that the hue can be visually recognized, and can be applied once or a plurality of times of two or more times.
The coating amount is not particularly limited, but the design material (Q) is preferably applied at 0.1 kg / m 2 or more and 1.4 kg / m 2 or less, and 0.2 kg / m 2 or more and 0.7 kg / It is more preferable to paint with m 2 or less.
工程（２）としては、工程（１）で塗装された意匠材（Ｐ）と意匠材（Ｑ）が混在する意匠面に対し、意匠材（Ｐ）と意匠材（Ｑ）が乾燥する前に、繊維質層の厚さが１０ｍｍ以下である繊維質ローラーを、押し当てて転動させる。 As the step (2), the design material (P) and the design material (Q) are dried on the design surface where the design material (P) and the design material (Q) painted in the step (1) are mixed. A fiber roller having a fiber layer thickness of 10 mm or less is pressed against and rolled.
意匠面を、繊維質ローラーを押し当てて転動させることにより、意匠材（Ｐ）、意匠材（Ｑ）を塗装した時の意匠を活かしつつ、表面を平坦化することができ、落ち着きのある自然の風合いを有する新たな意匠を形成することができる。 By rolling the design surface against the fiber roller, the surface can be flattened while making use of the design when the design material (P) and design material (Q) are applied, and the design surface is calm. A new design having a natural texture can be formed.
このような意匠の形成には、繊維質ローラーとして、繊維質層の厚さが１０ｍｍ以下（好ましくは２ｍｍ以上９ｍｍ以下、さらに好ましくは３ｍｍ以上８ｍｍ以下）であるものを用いる。
また、繊維の太さは５μｍ以上１５０μｍ以下（さらには８μｍ以上１００μｍ以下、さらには１０μｍ以上５０μｍ以下）であることが好ましい。
このような繊維質ローラーは、意匠材（Ｐ）、意匠材（Ｑ）が繊維質ローラーに付着しにくく、作業性に優れ、意匠面が適度に平坦化され、簡便に意匠を得ることができる。
なお、繊維質層の厚さとは、意匠材や水、溶剤等を含んでいない乾燥時の繊維質層の厚さのことである。また、本発明の繊維の太さとは、繊維の集合体である繊維束の断面直径のことであり、電子顕微鏡により測定した値である。
繊維質層の厚さが１０ｍｍを超えると、繊維質層に意匠材が付着してしまい、優れた意匠性が得られにくい。また、結合材がローラーにより多く付着するものと思われ、汚染性や、その他塗膜物性にも悪影響を及ぼすおそれがある。また、繊維質層の繊維筋が意匠材表面に形成されることもあり、意匠性に劣るものとなる。
繊維質ローラーとしては、特に限定されないが、アクリル繊維、ポリエステル繊維等の合成繊維、ウール等の動物性繊維、あるいは、これらを複合した繊維等が挙げられる。また、ハイパイル、織物等特に限定されない。
スポンジローラーでは、たとえスポンジ層の厚さを１０ｍｍ以下としても、スポンジ層に意匠材が付着しやすく作業性に劣る。また、スポンジによる新たな模様が形成されてしまい、平坦化は困難である。
For the formation of such a design, a fibrous roller having a fibrous layer thickness of 10 mm or less (preferably 2 mm or more and 9 mm or less, more preferably 3 mm or more and 8 mm or less) is used.
The thickness of the fiber is preferably 5 μm or more and 150 μm or less (more preferably 8 μm or more and 100 μm or less, more preferably 10 μm or more and 50 μm or less).
In such a fiber roller, the design material (P) and the design material (Q) are less likely to adhere to the fiber roller, excellent in workability, the design surface is appropriately flattened, and a design can be easily obtained. .
In addition, the thickness of a fibrous layer is the thickness of the fibrous layer at the time of drying which does not contain a design material, water, a solvent, etc. The thickness of the fiber of the present invention is a cross-sectional diameter of a fiber bundle that is an aggregate of fibers, and is a value measured by an electron microscope.
When the thickness of the fibrous layer exceeds 10 mm, the design material adheres to the fibrous layer, and it is difficult to obtain excellent design properties. In addition, it is considered that the binding material adheres more to the roller, which may adversely affect the contamination property and other physical properties of the coating film. Moreover, the fiber streaks of the fibrous layer may be formed on the surface of the design material, resulting in poor design properties.
Although it does not specifically limit as a fiber roller, Animal fibers, such as synthetic fibers, such as an acrylic fiber and a polyester fiber, wool, the fiber which compounded these, etc. are mentioned. Moreover, it is not specifically limited, such as a high pile and a woven fabric.
In the sponge roller, even if the thickness of the sponge layer is 10 mm or less, the design material tends to adhere to the sponge layer, and the workability is poor. In addition, a new pattern is formed by the sponge, and flattening is difficult.
本発明では、工程（１）、工程（２）で得られる意匠材表面は、凹凸構造を有するものである。特に、（Ｂ）成分である意匠骨材が含まれているため、意匠材表面から突出した意匠骨材が存在する場合がある。このような工程（１）、工程（２）で得られた凹凸構造をあえて平坦化することにより、落ち着きのある自然の風合いを有する新たな意匠が得られるものである。
本発明では、繊維質ローラーを押し当てて転動させることにより、突出した意匠骨材も適度に押さえて平坦化することができるとともに、意匠材（Ｐ）と意匠材（Ｑ）の色相が適度に混ざりあい、落ち着きのある自然の風合いを有する新たな意匠が得られる。
さらに、意匠材（Ｐ）と意匠材（Ｑ）を適度に押さえることによって、凹凸構造を平坦化するとともに、より緻密な表面構造を形成するため汚染物質の付着が抑制され、新たな意匠の創造とともに、汚染防止性にも優れるものである。
また、本発明では繊維質ローラーの繊維質層の厚さを１０ｍｍ以下とすることにより、押し当てる力の強弱があったとしても、適度に押さえることを可能にしたものである。
In the present invention, the surface of the design material obtained in the steps (1) and (2) has a concavo-convex structure. In particular, since the design aggregate which is the component (B) is included, there may be a design aggregate protruding from the design material surface. By deliberately flattening the concavo-convex structure obtained in steps (1) and (2), a new design having a calm natural texture can be obtained.
In the present invention, by pressing and rolling the fiber roller, the protruding design aggregate can be appropriately pressed and flattened, and the hues of the design material (P) and the design material (Q) are moderate. A new design with a calm and natural texture can be obtained.
Furthermore, by pressing down the design material (P) and the design material (Q) appropriately, the uneven structure is flattened, and the formation of a finer surface structure suppresses the adhesion of contaminants, creating a new design. At the same time, it also has excellent anti-contamination properties.
In the present invention, the thickness of the fibrous layer of the fibrous roller is set to 10 mm or less, so that even if the pressing force is strong or weak, it can be moderately pressed.
さらに、工程（２）では、水及び／または溶剤を含んだ繊維質ローラーを用いて、意匠材表面に押し当てて転動させることが好ましい。水及び／または溶剤を含むことによって、繊維質ローラーの転動がよりスムーズになり、繊維質ローラーに意匠材がいっそう付着しにくく、作業性に優れ、簡便に意匠を得ることができる。
繊維質ローラー中の水及び／または溶剤の含有量としては、繊維質部分において、繊維質単位体積あたり、水及び／または溶剤を１ｇ／ｃｍ３以上含むものが好ましい。このような範囲であることにより、繊維質ローラーを転動させた際、いっそう優れた意匠を形成することができる。
溶剤としては、例えばエチレングリコール、プロピレングリコール等の水易溶性溶剤や、芳香族炭化水素等の水難溶性溶剤から、意匠材（Ｐ）、意匠材（Ｑ）の組成等を考慮して、適宜選択すれば良い。
Furthermore, in the step (2), it is preferable to roll by pressing against the surface of the design material using a fibrous roller containing water and / or a solvent. By including water and / or a solvent, the rolling of the fibrous roller becomes smoother, the design material is less likely to adhere to the fibrous roller, the workability is excellent, and the design can be easily obtained.
The content of water and / or solvent in the fiber roller is preferably one containing 1 g / cm 3 or more of water and / or solvent per fibrous unit volume in the fibrous portion. By being in such a range, when the fibrous roller is rolled, a more excellent design can be formed.
The solvent is appropriately selected from, for example, readily water-soluble solvents such as ethylene glycol and propylene glycol, and poorly water-soluble solvents such as aromatic hydrocarbons in consideration of the composition of the design material (P) and design material (Q). Just do it.
本発明では、平坦化を行った後、公知の方法で硬化、乾燥させることによって、装飾面を形成することができる。
硬化、乾燥方法は、特に限定されず、常温、必要により加温して硬化、乾燥させればよい。

さらに硬化、乾燥後、必要に応じ、本発明の効果を損なわない程度に、装飾面の上に上塗材を塗装することもできる。上塗材としては、例えば、透明性を有する上塗材であれば、特に限定されない。例えば、上塗材に、親水性付与または撥水性付与することで、汚染防止性が付与できる。 Furthermore, after curing and drying, if necessary, a top coat material can be applied on the decorative surface to such an extent that the effects of the present invention are not impaired. The top coating material is not particularly limited as long as the top coating material has transparency, for example. For example, antifouling properties can be imparted to the topcoat material by imparting hydrophilicity or water repellency.
本発明では、工程（１）において、さらに前記意匠材（Ｐ）、意匠材（Ｑ）のいずれとも色相が異なる意匠材を塗装することにより、３色以上の意匠材が混在する装飾面を形成しても良い。
例えば、３色が混在する装飾面を得るためには、工程（１）において、意匠材（Ｒ）を、意匠材（Ｐ）の色相と意匠材（Ｑ）の色相と意匠材（Ｒ）の色相が混在するように塗装すれば良い。
この際の工程（１）としては、前述のように多頭ガン等を用いる方法や、（Ｐ）を塗装し、乾燥する前に（Ｑ）、（Ｒ）を部分塗装する方法がある。その後、前述の工程（２）の方法で平坦化すれば、３色が混在する意匠性に富んだ装飾面を形成することができる。
In the present invention, in the step (1), a decorative surface in which design materials of three or more colors are mixed is formed by coating a design material having a hue different from that of the design material (P) and the design material (Q). You may do it.
For example, in order to obtain a decorative surface in which three colors are mixed, in step (1), the design material (R) is replaced with the hue of the design material (P), the hue of the design material (Q), and the design material (R). What is necessary is just to paint so that a hue may be mixed.
Step (1) at this time includes a method using a multi-head gun or the like as described above, and a method of partially coating (Q) and (R) before coating (P) and drying. Then, if it planarizes by the method of the above-mentioned process (2), the decorative surface which was rich in the design property in which three colors were mixed can be formed.
また、本発明では、工程（１）において、意匠材（Ｐ）と意匠材（Ｑ）を塗装した後、さらに意匠材（Ｐ）を部分塗装することで、本発明の意匠性をさらに高めることもできる。 Moreover, in this invention, after coating the design material (P) and the design material (Q) in the step (1), the design material of the present invention is further enhanced by further partially painting the design material (P). You can also.
また、本発明では、目地材を用いて、区画化された意匠を表出してもよい。目地材としては、埋め込み型目地材、可剥型目地材等特に限定されない。
埋め込み型目地材の場合は、上記工程（１）の前に、基材に埋め込み型目地材を貼り付け（工程（１´））、その後工程（１）、工程（２）を行う。
また、可剥型目地材の場合は、上記工程（１）の前に、基材に可剥型目地材を貼り付け（工程（１´））、その後工程（１）、工程（２）を行い、工程（２）の後、意匠材が乾燥する前に可剥型目地材を取り外す。
また、可剥型目地材を取り外した後、さらに平坦化することもできる。このような方法では、より平坦化が可能であるとともに、目地部の仕上がり性が良好となり、新たな意匠の創造とともに、汚染防止性にも優れるものである。
Moreover, in this invention, you may express the segmented design using joint material. The joint material is not particularly limited, such as an embedded joint material and a peelable joint material.
In the case of the embedded joint material, the embedded joint material is attached to the base material (step (1 ′)) before the step (1), and then the step (1) and the step (2) are performed.
In the case of a peelable joint material, the peelable joint material is attached to the base material before the step (1) (step (1 ′)), and then the steps (1) and (2) are performed. And after the step (2), the peelable joint material is removed before the design material is dried.
