Description
本発明は、既存の石材やタイル等の模様付け被処理対象物に施工し、床面や壁面を石材調に仕上げて意匠性を高める、ＭＭＡ（Methyl methacrylate）樹脂を用いたストーンカラー工法に関するものである。 The present invention relates to a stone color construction method using MMA (Methyl methacrylate) resin, which is applied to existing patterned objects such as stones and tiles to improve the design by finishing floors and walls with a stone look. It is.
近年、例えば、特許文献１に開示されているように、カラーストーンによる敷石や園芸用の石材が提供されている。カラーストーンは、微粒状の石材に着色を施した着色砂（カラーサンド）であり、状況に応じた多彩なアレンジができ、劣化に強く、環境保全にも貢献する。 In recent years, paving stones and gardening stones made of colored stones have been provided, for example, as disclosed in Patent Document 1. Colored stones are colored sand made by applying color to fine-grained stones.They can be arranged in a variety of ways depending on the situation, are resistant to deterioration, and contribute to environmental conservation.
また、床等の表面仕上げには、防水性に加えて耐薬品性、耐久性も高いメタクリル樹脂のトップコートが採用されている。メタクリル樹脂のトップコートは、ローラーや鏝で一定の厚みを付けることによりワックスの薄い膜を形成し、空気中の酸素を遮断することで重合反応が起こって硬化する。 Additionally, a methacrylic resin top coat, which is not only waterproof but also chemically resistant and highly durable, is used to finish the floors and other surfaces. Methacrylic resin top coats are made by applying a certain thickness with a roller or trowel to form a thin film of wax, which then undergoes a polymerization reaction and hardens by blocking oxygen from the air.
しかしながら、上記カラーストーンは、微粒状の石材に着色を施すだけであるため、意匠が制限されるという課題があった。 However, since the above-mentioned colored stones are simply colored finely granular stones, there is a problem in that the designs are limited.
また、メタクリル樹脂のトップコートは、ローラーや鏝等で厚みを付けて施工しないとラジカル重合反応で硬化しないため、施工箇所が限られてしまい、床面のような平面に対する使用に限られている。 In addition, methacrylic resin top coats do not harden through radical polymerization unless they are applied thickly using a roller or trowel, so the application areas are limited and their use is limited to flat surfaces such as floors. .
そこで、本発明は如上のような従来存した諸事情に鑑み創出されたもので、意匠性を向上できると共に、施工面の制限をなくして様々な箇所に施工できる、ＭＭＡ樹脂を用いたストーンカラー工法を提供することを目的とする。 Therefore, the present invention was created in view of the existing circumstances as described above, and is a stone color using MMA resin that can improve the design and can be applied to various locations without restrictions on the construction surface. The purpose is to provide construction methods.

a resin overcoating step in which the patterned object subjected to the base treatment is recoated with MMA (Methyl methacrylate) resin;
A resin surface design step of applying a top coat of MMA resin before the resin is cured by spraying MMA resin on the object to be treated that has been subjected to the repainting treatment,
The resin coating step includes coating the surface-treated object with a primer made of MMA resin, and using an MMA resin mortar that is a combination of a liquid resin mainly composed of MMA resin and various aggregates.

Spraying of MMA resin in the resin surface design process involves spraying a plurality of MMA resins colored in different colors with viscosities of 100 [Pa·s] to 180 [Pa·s] into mountain-like convex parts using a spray gun. This process involves spraying the MMA resin in a linear or beaded manner multiple times before it hardens, and then applying the top coat with a roller or brush after spraying the MMA resin. , the above-mentioned problems were solved.
この請求項１に係るＭＭＡ樹脂を用いたストーンカラー工法によれば、着色したＭＭＡ樹脂を、吹き付けガンを使用して散布して硬化反応させることで、単色のみならず様々な色彩パターンによる模様付けを行うことができ、明るさや華やかさ等の様々な視覚的効果を与え、意匠性を向上させることができる。また、平面でしかラジカル重合反応で硬化しなかった従来のメタクリル樹脂に対して、ＭＭＡ樹脂に粘度を持たせることにより、法面、立面、上げ裏面でも容易に硬化させることが可能となり、石材やタイル等の既存の床面や手洗い場等、様々な箇所に施工できる。
また、樹脂塗り重ね工程は、ＭＭＡ樹脂の早い硬化性のため、ＭＭＡ樹脂の重ね塗り施工を短時間で行うことができ、多色模様の仕上がりが容易となる。しかも、樹脂表面意匠工程においては、ＭＭＡ樹脂の強度や塗厚の向上を確保でき、またＭＭＡ樹脂の塗りムラやダレをボカス作業も可能となる。

更にまた、ＭＭＡ樹脂が硬化する前に複数回の吹き付けを行うため、ラジカル重合反応によるＭＭＡ樹脂同士の結合を強くすることができ、色のグラディエーションが可能となる。このような色重ねの容易性によって、美観的及び意匠的な深みを十分に出すことができる。しかも、異なる色のＭＭＡ樹脂の調合及び吹き付けガンの吐出調整により、異なる色のＭＭＡ樹脂相互の粘度の調整が可能で、様々な色彩パターンによる模様付けを容易に行うことができる。
加えて、ＭＭＡ樹脂で線状または玉状に何色にも渡り模様を吹き付けることで、模様付け後の意匠性を向上させることができる。例えば、建築物や土木公共事業における石材やタイル等の既存の床面や手洗い場等を、複数の異なる色に模様付けできる。
また、ＭＭＡ樹脂の吹き付け凹凸模様により防滑性を兼ね備え、従来の珪砂による防滑処理よりも清掃性を格段に向上させ、模様付けにも適したものとなる。
According to the stone color construction method using MMA resin according to claim 1, by spraying colored MMA resin using a spray gun and causing a curing reaction, patterns can be created not only in a single color but also in various color patterns. It is possible to provide various visual effects such as brightness and gorgeousness, and improve the design quality. In addition, unlike conventional methacrylic resins that only harden on flat surfaces through radical polymerization reactions, by giving MMA resin a viscosity, it can be easily hardened on sloped surfaces, vertical surfaces, and raised surfaces. It can be installed in a variety of locations, including existing floor surfaces such as floor tiles and hand washing areas.
Furthermore, in the step of overcoating the resin, due to the fast curing properties of the MMA resin, the overcoating of the MMA resin can be performed in a short time, making it easy to finish a multicolored pattern. Moreover, in the resin surface design process, it is possible to ensure improvement in the strength and coating thickness of the MMA resin, and it is also possible to focus on uneven coating and sagging of the MMA resin.
Further, by applying the MMA resin with a roller or a brush after the MMA resin has been sprayed, the sprayed pattern can be suppressed, thereby making it possible to easily impart color gradation.
Furthermore, since the spraying is performed multiple times before the MMA resin is cured, the bond between the MMA resins can be strengthened by the radical polymerization reaction, and color gradation can be achieved. This ease of color overlapping allows for sufficient aesthetic and design depth. Moreover, by mixing MMA resins of different colors and adjusting the discharge of the spray gun, it is possible to adjust the mutual viscosity of the MMA resins of different colors, and it is possible to easily create patterns with various color patterns.
In addition, by spraying a linear or beaded pattern of multiple colors using MMA resin, the design quality after patterning can be improved. For example, existing floor surfaces such as stones and tiles in buildings and civil engineering public works projects, hand washing areas, etc. can be patterned in a plurality of different colors.
In addition, the sprayed uneven pattern of the MMA resin provides anti-slip properties, making it much easier to clean than the conventional anti-slip treatment using silica sand, making it suitable for patterning.

In the third aspect of the present invention, the spray gun has a pattern width of 90 [mm] to 110 [mm], a discharge amount of 90 [ml/min] to 100 [ml/min], and an air amount of 70 [ml/min]. l/min] to 80 [l/min], the above-mentioned problem was also solved.
この請求項３に係るＭＭＡ樹脂を用いたストーンカラー工法によれば、粘度が１００［Ｐａ・ｓ］～１８０［Ｐａ・ｓ］のＭＭＡ樹脂を吹き付ける際に、吹き付けガンの吐出調整を行って、吹き付けガンのパターン幅を９０［ｍｍ］～１１０［ｍｍ］、吐出量を９０［ｍｌ／ｍｉｎ］～１００［ｍｌ／ｍｉｎ］、エア量を７０［ｌ／ｍｉｎ］～８０［ｌ／ｍｉｎ］とすることで施工面の制限をなくし、ＭＭＡ樹脂を、法面、立面、上げ裏面でも重合硬化させることができる。 According to the stone color construction method using MMA resin according to claim 3 , when spraying the MMA resin having a viscosity of 100 [Pa·s] to 180 [Pa·s], the discharge of the spray gun is adjusted, The pattern width of the spray gun is 90 [mm] to 110 [mm], the discharge amount is 90 [ml/min] to 100 [ml/min], and the air amount is 70 [l/min] to 80 [l/min]. By doing so, there are no restrictions on the construction surface, and the MMA resin can be polymerized and cured even on sloped surfaces, vertical surfaces, and raised back surfaces.
本発明によれば、ＭＭＡ樹脂を塗り重ねた被処理対象物に、吹き付けガンを用いて着色したＭＭＡ樹脂を散布し、ＭＭＡ樹脂が硬化する前に、ＭＭＡ樹脂のトップコート塗布を行うことで、複数の異なる色に模様付けして意匠性を向上させることができる。また、樹脂に粘度を持たせることで、メタクリル樹脂が法面、立面、上げ裏面でも重合反応硬化するので、施工面の制限をなくして様々な箇所に施工できる。 According to the present invention, by spraying colored MMA resin using a spray gun on the object to be treated that has been repeatedly coated with MMA resin, and applying a top coat of MMA resin before the MMA resin hardens, The design can be improved by patterning in multiple different colors. In addition, by adding viscosity to the resin, the methacrylic resin polymerizes and hardens even on sloped surfaces, vertical surfaces, and raised surfaces, so it can be applied to a variety of locations without restrictions on the construction surface.

It is also a good resin. The coated film itself is resistant to discoloration and fading due to ultraviolet rays, and can be applied both indoors and outdoors. It also has excellent chemical resistance and is easy to maintain hygiene. Furthermore, it has the property of being extremely hard to break. In addition, in the following description, it will be abbreviated as MMA resin.
本実施形態における工法は、図１に示すように、石材やタイル等からなる既存の床面や手洗い場等の模様付け被処理対象物に、下記Ａ～Ｃの工程を順次行うことにより、模様付け被処理対象物に意匠価値の高い模様付けが仕上がるようにするものである。 As shown in FIG. 1, the construction method in this embodiment is to create a pattern by sequentially performing the following steps A to C on an existing floor surface made of stone or tile, or on an object to be patterned such as a hand-washing area.

樹脂塗り重ね工程Ｂでは、まず、上記下地処理工程Ａによって下地処理をした石材やタイル等からなる既存の床面や手洗い場等に、ＭＭＡ樹脂によるプライマー塗装処理ａを行う。 In the resin overcoating process B, first, a primer coating process a using MMA resin is performed on the existing floor surface, hand washing area, etc. made of stone, tiles, etc. that have been subjected to the base treatment in the above-mentioned base treatment process A.

Further, an intermediate coating process c using an MMA paste resin, a putty process d using an MMA resin, a soft coating process e using an MMA soft resin are sequentially performed, and finally a top coat coating process f using an MMA resin is performed.
プライマー塗装処理ａに使用されるＭＭＡプライマー樹脂材は、品名：ＳＰ１１５（オリジナル品名）のＭＭＡ樹脂を０．３ｋｇ／ｍ2 とする。 The MMA primer resin material used in primer coating treatment a is 0.3 kg/m 2 of MMA resin with product name: SP115 (original product name).

尚、硬化剤としては、品名：ＢＰＯ－５０の硬化剤を３％とする。 As for the hardening agent, 3% of the hardening agent, product name: BPO-50, is used.
樹脂表面意匠工程Ｃにおける樹脂散布処理ｇは、異なる色に着色したＭＭＡ樹脂の吹き付けを、吹き付けガンを用いて行う。ＭＭＡ樹脂の粘度は、従来の１８０［Ｐａ・ｓ］～２９０［Ｐａ・ｓ］よりも高く、１００［Ｐａ・ｓ］～１８０［Ｐａ・ｓ］の範囲内であり、粘度が高いことで樹脂液がラジカル重合反応を行い、法面、立面、上げ裏面でも常温硬化する。また、吹き付けガンの吐出調整により、本例においては、吹き付けられる樹脂のパターン幅は９０［ｍｍ］～１１０［ｍｍ］の範囲、例えば１００［ｍｍ］である。また、吐出量は９０［ｍｌ／ｍｉｎ］～１００［ｍｌ／ｍｉｎ］の範囲、例えば９５［ｍｌ／ｍｉｎ］であり、エア量は７０［ｌ／ｍｉｎ］～８０［ｌ／ｍｉｎ］の範囲、例えば７５［ｍｌ／ｍｉｎ］にそれぞれ設定している。 In the resin spraying treatment g in the resin surface design step C, MMA resins colored in different colors are sprayed using a spray gun. The viscosity of MMA resin is higher than the conventional 180 [Pa・s] to 290 [Pa・s] and is within the range of 100 [Pa・s] to 180 [Pa・s]. The liquid undergoes a radical polymerization reaction and cures at room temperature even on sloped, vertical, and raised surfaces. Further, by adjusting the discharge of the spray gun, in this example, the pattern width of the sprayed resin is in the range of 90 [mm] to 110 [mm], for example, 100 [mm]. Further, the discharge amount is in the range of 90 [ml/min] to 100 [ml/min], for example, 95 [ml/min], and the air amount is in the range of 70 [l/min] to 80 [l/min], For example, each is set to 75 [ml/min].
この樹脂散布処理ｇでは、上述したような吹き付けガンを用いたＭＭＡ樹脂の吹き付けを複数回行う。この際、異なる色のＭＭＡ樹脂の調合と吹き付けガンの吐出調整により、異なる色のＭＭＡ樹脂相互の粘度の調整が可能であり、様々な色彩パターンによる模様付けを容易に行うことができる。 In this resin spraying process g, the MMA resin is sprayed multiple times using a spray gun as described above. At this time, by mixing the MMA resins of different colors and adjusting the discharge of the spray gun, it is possible to adjust the mutual viscosity of the MMA resins of different colors, and it is possible to easily create patterns with various color patterns.
例えば、３回の色違いの吹き付けで、塗り床に凹凸感のあるグラディエーションを出すことができる。あるいは、吹き付けガンを用いての異なる色に着色したＭＭＡ樹脂の複数回の吹き付けで、ベース７０％、メイン２５％、アクセント５％の色彩パターン（ドミナントカラー）とすることもできる。 For example, by spraying three different colors, you can create an uneven gradation on the painted floor. Alternatively, a color pattern (dominant color) of 70% base, 25% main, and 5% accent can be created by spraying MMA resin colored in different colors multiple times using a spray gun.
更に、樹脂表面意匠工程Ｃにおける樹脂散布処理ｇでは、ＭＭＡ樹脂による塗り床に、異なる色に着色したＭＭＡ樹脂を、吹き付けガンを用いて線状又は玉状に吹き付けるものとしても良い。この工程により、ＭＭＡ樹脂による塗り床に、緩やかな山状の凸部が形成される。 Furthermore, in the resin spraying treatment g in the resin surface design step C, MMA resins colored in different colors may be sprayed in a linear or beaded manner onto the MMA resin painted floor using a spray gun. Through this step, gentle mountain-like convex portions are formed on the MMA resin coating floor.
樹脂表面意匠工程Ｃの樹脂散布処理ｇの後には、トップコート塗布処理ｈ（クリアトップコート）にて、ＭＭＡ樹脂をローラー又は刷毛で塗布することで、樹脂散布処理ｇによって吹き付け散布された樹脂を押えることができ、これによって色のグラディエーションを付けることができる。 After the resin spraying treatment g of the resin surface design step C, MMA resin is applied with a roller or brush in the top coat application treatment h (clear top coat), thereby removing the resin sprayed in the resin spraying treatment g. This allows you to create color gradations.
以上説明したように、本実施形態においては、異なる色に着色したＭＭＡ樹脂による色彩パターンを使うことにより、従来にはなかった意匠性の高い模様付け仕上げが可能となる。しかも、明るさや華やかさ等の様々な視覚的効果を与えることができる。特に、樹脂塗り重ね工程は、ＭＭＡ樹脂の早い硬化性のため、ＭＭＡ樹脂の重ね塗り施工を短時間で行うことができ、多色模様の仕上がりが容易となる。 As explained above, in this embodiment, by using color patterns of MMA resins colored in different colors, it is possible to achieve a patterned finish with a high degree of design, which was not possible in the past. Moreover, various visual effects such as brightness and gorgeousness can be provided. In particular, in the step of overcoating the resin, due to the fast curing properties of the MMA resin, the overcoating of the MMA resin can be performed in a short time, making it easy to finish a multicolored pattern.
また、樹脂に粘度を持たせることで、メタクリル樹脂が法面、立面、上げ裏面でも重合反応硬化するので、施工面の制限をなくして様々な箇所に施工できる。 In addition, by adding viscosity to the resin, the methacrylic resin polymerizes and hardens even on sloped surfaces, vertical surfaces, and raised surfaces, so it can be applied to a variety of locations without restrictions on the construction surface.
更に、ＭＭＡ樹脂の吹き付け凹凸模様により防滑性を兼ね備えることで、従来の珪砂による防滑処理よりも清掃し易くして、石材やタイル等の床面や手洗い場等のＭＭＡ樹脂模様付けに適したものとすることができる。 Furthermore, the sprayed uneven pattern of MMA resin provides anti-slip properties, making it easier to clean than the conventional anti-slip treatment using silica sand, making it suitable for applying MMA resin patterns to floor surfaces such as stone and tiles, hand washing areas, etc. It can be done.
尚、例示はしないが、本発明は、上述した実施形態に限定されるものではなく、その趣旨を逸脱しない範囲内において、種々の変更が加えられて実施可能である。 Although not illustrated, the present invention is not limited to the embodiments described above, and can be implemented with various modifications within the scope of the invention.
本発明は、建築物や土木公共事業等における石材やタイル等の既存の床面や手洗い場等に施工されるもの以外に、石材やタイル等の既存の壁材や階段等の模様付け手法として、種々の作業現場において、幅広く利用できるものである。 In addition to being applied to existing floor surfaces such as stone and tiles, washrooms, etc. in buildings, civil engineering public works, etc., the present invention can also be used as a patterning method for existing wall materials such as stone and tiles, stairs, etc. , can be widely used in various work sites.
