Description
本発明は天井化粧板に対する耐傷性に優れた新規な濃色塗膜の形成方法に関する。 The present invention relates to a method for forming a novel dark color coating film excellent in scratch resistance for a decorative ceiling board.
商業施設や公共施設での天井化粧板では、防火性能や吸音性能が求められるため、ポーラスで不燃性の基材であるロックウール吸音板からなる天井化粧板を施工する場合が多いのであるが、白色等の淡色に限らず使用空間に合わせて焦げ茶や紺色或いは黒等の濃色を使った表面に仕上げることがある。例えば、美術館、映画館、プラネタリューム館などの室内照明を落として暗くする必要のある空間に使用される天井化粧板では、焦げ茶や紺色或いは黒色に仕上げることがある。天井化粧板の表面を濃色にするには、例えばカーボンブラックや鉛丹、紺青等の顔料を添加して濃色に着色した塗料で塗装することで一定程度対応可能である。 In ceiling decorative panels in commercial and public facilities, fireproof performance and sound absorbing performance are required, so there are many cases where ceiling decorative panels made of rock wool sound absorbing boards, which are porous and non-combustible base materials, are constructed. The surface may be finished using dark colors such as dark brown, dark blue, or black according to the usage space, not limited to light colors such as white. For example, a ceiling decorative board used in a space that needs to be darkened by dropping indoor lighting, such as a museum, a movie theater, or a planetarium, may be finished in dark brown, dark blue, or black. In order to darken the surface of the ceiling decorative board, for example, a pigment such as carbon black, red lead, and bitumen can be added and painted with a paint colored darkly to some extent.
ところが、ロックウール吸音板からなる天井化粧板の表面はポーラスかつ繊維状であることから塗装ムラになり易く、或いは、斜光を受けた場合に当該部分の塗膜部分に部分的な乱反射が起こり易くて、天井全面において深い濃色あるいは真の濃色を表現することが難しかった。 However, the surface of the ceiling decorative panel made of rock wool sound-absorbing board is porous and fibrous, so it tends to be uneven in coating, or when it receives oblique light, partial irregular reflection is likely to occur in the coating film part of the part. Therefore, it was difficult to express a deep dark color or a true dark color on the entire ceiling.
また、天井化粧板を現場施工する際には前記濃色の場合、擦れた部分や当たった部分が白っぽく変色するなど擦り傷や打ち傷がつき易く、これらが外観欠点として目立ち易くなるという問題もあった。 In addition, when the ceiling decorative panel is constructed in the field, in the case of the dark color, there is also a problem that the rubbed part or the struck part tends to be whitish or scratched, and these are easily noticeable as appearance defects. .
このようなポーラスかつ繊維状の天井化粧板の表面と異なり、表面状態が平坦且つ平滑であれば、着色塗料での塗装であっても、艶や光沢のある漆調の濃色に塗装表現することは可能である。黒色であれば所謂ピアノブラックと呼ばれるような艶や光沢のある漆黒調である。例えば漆黒性を高める塗膜構造には、特許文献1のような技術も開示されている。また、耐傷性を高めるには塗料の樹脂量を増やして塗膜強度を上げることも考えられる。
Unlike the surface of such a porous and fibrous ceiling veneer, if the surface state is flat and smooth, even if it is painted with a colored paint, it is painted and expressed in a glossy and glossy lacquer-like dark color It is possible. If it is black, it is a jet-black tone with luster and luster that is called piano black. For example, a technique such as
しかしながら、そもそも艶や光沢のある濃色は内装用の天井化粧板としては落ち着きが得られなくなるので、むしろ艶はない方がよいとされている。艶をなくすためにシリカなどの鉱物や透明粒子を添加して調整することも出来るが、このようにした場合、明度が変化してしまって色としてはむしろ鈍い(霞がかかったような)印象の濃色になってしまう。 However, it is said that the glossy or glossy dark color should not be glossy because it can no longer be settled as a ceiling decorative board for interior use. In order to eliminate gloss, minerals such as silica and transparent particles can be added and adjusted. However, when this is done, the lightness changes and the color is rather dull (hazy) It will become a dark color.
また、一般的に塗料の樹脂量が増えると樹脂による艶が出てしまうことになるだけでなく、表面がポーラス且つ繊維状であるため細かい凹凸のあるロックウール吸音板に塗布することで光沢ムラも出易くなってしまう。また、特許文献1に記載の発明は漆黒色が意図されている技術であるが、鋼板のような平坦な基材に塗膜を形成する技術であって、ポーラスで繊維状の基材への単純適用は困難である。
Also, in general, when the amount of resin in the paint increases, not only the gloss due to the resin will appear, but also because the surface is porous and fibrous, it can be applied to a rock wool sound absorbing plate with fine irregularities, resulting in uneven gloss. It becomes easy to come out. The invention described in
本発明はかかる従来例に鑑みてなされたもので、ポーラス且つ繊維状で細かい凹凸のある表面を有するロックウール吸音板からなる天井化粧板に対し、艶を与えずに落ち着きのある深い濃色或いは真の濃色に表現することができ且つ耐傷性も向上させることのできる天井化粧板の塗膜形成方法の開発がその課題である。 The present invention has been made in view of such a conventional example, and it is a deep dark color that is calm without giving gloss to a ceiling decorative board made of a rock wool sound absorbing board having a porous and fibrous surface with fine irregularities. The challenge is to develop a method of forming a coating film for a ceiling decorative board that can be expressed in a true dark color and can also improve scratch resistance.

請求項3に記載の塗膜の形成方法は、
上塗り塗料に、上塗り(13)が重ねあわされる下の層の塗料と同系統色の濃色着色剤が更に添加されていることを特徴とする。
The method for forming a coating film according to claim 3 comprises:
It is characterized in that a deep colorant having the same color as that of the paint in the lower layer on which the top coat (13) is superimposed is further added to the top coat.
本発明によれば、粒子(14)の直径より薄い膜厚の上塗り(13)の直下に、マンセル値が明度4.5以下である下又は中塗り(11)(12)の塗膜が塗布されているので、薄い膜厚の上塗り(13)から下又は中塗り(11)(12)の塗膜の濃色が透けて見え、表面側からは下又は中塗り(11)(12)の塗膜によってロックウール吸音板(10)の表面地色が確実に隠されて外に現れず、そして、下又は中塗り(11)(12)の塗料と同系統の濃色粒子(14)は、上塗り(13)の塗膜から少し出ている(頭をのぞかせた)状態なので、頭をのぞかせた濃色粒子(14)の濃色と、該粒子(14)間の隙間を埋めるように同系統色の下又は中塗り(11)(12)の塗膜の濃色が薄い上塗り(13)の塗膜を通して見え、粒子(14)の影によるより暗い濃色が上塗り(13)に映じて立体感を出し、且つ粒子(14)の存在によって表面全面にわたって適度な光の拡散が均一に起こることで、艶のない落ち着いた深い濃色或いは真の濃色が天井化粧板(1)の全面においてバラつきなく感得できるようになる。 According to the present invention, immediately below the top coat (13) having a film thickness smaller than the diameter of the particles (14), a coating of a bottom or intermediate coat (11) (12) having a Munsell value of 4.5 or less in brightness is applied. As a result, the dark color of the thin film of the top coat (13) to the bottom or middle coat (11) (12) can be seen through, and from the surface side the bottom or middle coat (11) (12) The surface ground color of the rock wool sound absorbing plate (10) is surely hidden by the coating and does not appear outside, and the dark particles (14) in the same system as the paint of the undercoat or intermediate coat (11) (12) are Since it is slightly out of the top coat (13) (with the head peeked out), the dark color of the dark particle (14) over the head and the gap between the particles (14) are filled. The dark color of the undercoat or middle coat (11) (12) of the system color is visible through the thin coat (13), and the darker shade due to the shadow of the particles (14) is reflected in the overcoat (13). It gives a three-dimensional effect, and over the entire surface due to the presence of particles (14) Appropriate diffusion of light occurs uniformly, so that it is possible to perceive a calm deep dark color or true dark color on the entire surface of the ceiling decorative board (1) without variation.
そして、上塗り塗料にも下又は中塗り塗料或いは濃色粒子(14)と同系統の濃色の着色料を添加しておけば、下又は中塗り(11)(12)或いは濃色粒子(14)の濃色と協働してより一層落ち着いた深い濃色或いは真の濃色を現出させることが出来る。 If the same color as the lower or intermediate coating or dark colored particles (14) is added to the upper coating, the lower or intermediate coating (11) (12) or dark colored particles (14 ) In combination with the dark color of), a deeper dark color or a true dark color can appear.
加えて前述のように、粒子(14)が上塗り(13)の塗膜よりも外に出ている状態なので、表面に物が当たったり接触して擦れたとしても、これらは粒子(14)に接触して上塗り(13)の塗膜に直接接触せず、上塗り(13)の塗膜自体の傷つきが防止されるため施工時において表面に傷が付きにくい。 In addition, as described above, since the particles (14) are outside the coating film of the top coat (13), even if the object hits the surface or is rubbed due to contact, they are not applied to the particles (14). The coating of the top coat (13) does not come into direct contact with the coating and the coating of the top coating (13) is prevented from being scratched, so that the surface is hardly scratched during construction.
以下、本発明を図示実施例に従って説明する。本発明に使用される吸音板(10)は、ロックウール繊維をバインダにて板状に固めたもので、その表面には繊維に起因する微細な浅い凹凸が全面にわたって形成されており、更に内部に向かってある程度の深さを有する微細な吸音用のピン孔(図示せず)が多数表面側に形成されており、吸音性、防燃耐火性に優れ所謂天井板として多用されている。 The present invention will be described below with reference to the illustrated embodiments. The sound-absorbing plate (10) used in the present invention is obtained by solidifying rock wool fibers in a plate shape with a binder, and on the surface thereof, fine shallow irregularities due to the fibers are formed over the entire surface. A large number of fine sound-absorbing pin holes (not shown) having a certain depth toward the surface are formed on the surface side, and are excellent in sound-absorbing property and fire-proof and fire-resistant properties, and are often used as so-called ceiling boards.
吸音板(10)の表面には樹脂塗料を塗布して化粧用の塗膜が形成される。塗膜には下塗り(11)と上塗り(13)の2塗膜構成のものと、下、中及び上塗り(11)(12)(13)の3塗膜構成のものがある。濃色の着色剤が添加されるのは少なくとも上塗り(13)の直下に当たる層、前者では下塗り(11)、後者では中塗り(12)となる。 A resin coating is applied to the surface of the sound absorbing plate (10) to form a cosmetic coating film. There are two types of coating films, namely, a base coating (11) and a top coating (13), and a coating layer having three coatings: a bottom coating, a middle coating and a top coating (11), (12) and (13). The dark colorant is added to at least the layer immediately below the topcoat (13), the undercoat (11) in the former and the intermediate coat (12) in the latter.
尚、下塗り(11)と上塗り(13)の二塗膜構造であっても、下塗り(11)の塗布量を多くすることで本発明のような深い濃色を表現することは可能であるが、塗料の乾燥効率が低下して生産性が低いため、3塗膜構成にすることが望ましい。以下、3塗膜構成の場合の形態を説明し、その中で2塗膜構成の場合を説明する。 Even in the case of a two-coat structure of the undercoat (11) and the topcoat (13), it is possible to express a deep dark color as in the present invention by increasing the amount of the undercoat (11) applied. Since the drying efficiency of the paint is lowered and the productivity is low, it is desirable to have a three-coat film configuration. Hereinafter, the form in the case of 3 coating-film structure is demonstrated, and the case of 2 coating-film structure is demonstrated in it.
3塗膜構成の場合では、最下塗膜となる下塗り(11)用の塗料は特に選ばれないが、例えば、酢酸ビニルエマルジョン樹脂塗料やアクリルエマルジョン樹脂塗料などの一般的な水性樹脂塗料でよい。色は濃色が望ましいが、白色その他の色でも構わない。150〜200g/m2の塗布量でロックウール吸音板(10)の表面に塗布する。150g/m2より少ないと基材色であるロックウール吸音板(10)の表面色の隠蔽性が低下し、地色が透けてしまう。また、中塗り塗料の目止め剤としての効果も低下してしまう。200g/m2より多いと塗料の使用量が多過ぎて経済性の低下とともに乾燥が困難となり生産性も低下するからである。塗料の塗布手段はナチュラルコーターやスプレーコーターなど既知の手段で構わない。 In the case of the three-coat film configuration, the paint for the undercoat (11) that becomes the bottom coat is not particularly selected, but for example, a general aqueous resin paint such as a vinyl acetate emulsion resin paint or an acrylic emulsion resin paint may be used. . The color is preferably dark, but may be white or other colors. It apply | coats to the surface of a rock wool sound-absorbing board (10) with the application quantity of 150-200 g / m < 2 >. If it is less than 150 g / m 2, the concealability of the surface color of the rock wool sound-absorbing plate (10), which is the base material color, is lowered, and the ground color is transparent. In addition, the effect of the intermediate coating material as a filler is also reduced. This is because if the amount is more than 200 g / m 2, the amount of the coating material used is too large, the drying is difficult and the productivity is lowered as the economy is lowered. The coating means may be a known means such as a natural coater or a spray coater.
上記に対して2塗膜構成の場合では、下塗り(11)が中塗り(12)を兼ねるため前述のように濃色の塗料を添加すると共に下塗り(11)の塗布量を多くすることになる。塗布量は150〜220g/m2でロックウール吸音板(10)の表面に塗布する。150g/m2より少ないと前述のように基材色の隠蔽性が低下し、地色が透けてしまう。逆に220g/m2より多いと塗料の使用量が多過ぎて経済性の低下とともに乾燥が困難となり生産性も低下するだけでなく吸音用のピン穴を塞いでしまって吸音効果が低下することになる。樹脂塗料は前述の下塗り用の塗料に準じ、濃色の着色剤は次に述べる3塗膜構成の中塗りに準ずる。 In contrast to the above, in the case of the two coating film configuration, the undercoat (11) also serves as the intermediate coat (12), so that the dark paint is added and the amount of the undercoat (11) applied is increased as described above. . The coating amount is 150 to 220 g / m 2 and is applied to the surface of the rock wool sound absorbing plate (10). When the amount is less than 150 g / m 2 , the concealability of the base color is lowered as described above, and the ground color is transparent. On the other hand, if the amount exceeds 220 g / m 2 , the amount of paint used is too large, and it is difficult to dry as the economy decreases, resulting in a decrease in productivity, as well as blocking the sound-absorbing pin holes and reducing the sound absorption effect. become. The resin paint conforms to the above-described undercoat paint, and the dark colorant conforms to the intermediate coat of the three coating composition described below.
中塗り(12)用の塗料は、下塗り(11)用の塗料と同様の酢酸ビニルエマルジョン樹脂塗料やアクリルエマルジョン樹脂塗料などの一般的な水性樹脂塗料でよいが、着色剤を添加して濃色にした塗料とする。 The paint for the intermediate coat (12) may be a common water-based resin paint such as a vinyl acetate emulsion resin paint or an acrylic emulsion resin paint similar to the paint for the undercoat (11). It is assumed that the paint is made.
着色剤は特に選ばれないが、例えばカーボンブラック、鉛丹、紺青等の顔料が用いられる。濃色レベルは、マンセル値の明度で4.5以下とする。例えば無彩色(黒色)であればN4.5以下となる。4.5を超えると希望する濃色が得られにくくなるからである。また、単一色に限らず、黒色に赤色や青色など他の色が混ざっていてもよい。 The colorant is not particularly selected, and pigments such as carbon black, red lead, and bitumen are used. The dark color level is 4.5 or less in terms of Munsell brightness. For example, if the color is achromatic (black), N4.5 or less. This is because if it exceeds 4.5, it becomes difficult to obtain a desired dark color. In addition to the single color, other colors such as red and blue may be mixed with black.
中塗り(12)では140〜190g/m2の塗布量で塗布する。140g/m2より少ないと、密度が疎になってしまって安定的な濃色効果が得られず、下塗り(11)の色がまだらに透けて見えるからであり、190g/m2より多いと乾燥効率が低下するだけでなく、前述のように吸音用のピン穴を塞いでしまって吸音効果が低下するからである。この場合も塗布手段は前述のナチュラルコーター、スプレーコーター、或いはカーテンフローコーターなど既知の手段で構わない。 The intermediate coating (12) is applied at a coating amount of 140 to 190 g / m 2 . If it is less than 140 g / m 2 , the density becomes sparse and a stable dark color effect cannot be obtained, and the color of the undercoat (11) can be seen through, and if it is more than 190 g / m 2 This is because not only the drying efficiency is lowered, but also the sound absorbing effect is lowered by closing the sound absorbing pin hole as described above. Also in this case, the application means may be a known means such as the above-mentioned natural coater, spray coater, or curtain flow coater.
上塗り(13)用の塗料も同様に、酢酸ビニルエマルジョン樹脂塗料やアクリルエマルジョン樹脂塗料などの一般的な水性樹脂塗料でよいが、濃色粒子(14)を添加したものとする。上塗り(13)用の塗料は着色剤を添加しない場合、透明を始め、半透明でも良く、重ね塗りされた下の層の色が透けて見えるようなものであれば足る。着色剤を添加する場合は、濃色粒子(14)と同系統の色が選択される。粒子(14)間の隙間(14a)も同系統色が現れるため、濃色粒子(14)の影が上塗り(13)に映じて立体的でより効果的な深味のある濃色が得られる。既に述べたように上塗り(13)用の塗料にはシリカなどの鉱物や透明粒子は添加しない。添加するとこれらが上塗り(13)の塗膜表面に不規則な微細凹凸を生じさせて塗膜表面の艶や光沢を消す効果はあるものの、一方でシリカなどの鉱物や透明粒子が濃色粒子(14)と重なって明度が変化してしまい、濃色としてはむしろ鈍い印象(くすんだ印象、霞のかかった印象など)を与えることになるからである。なお、2塗膜構成の場合は、上塗り用塗料に着色剤を添加することが望ましい。 Similarly, the paint for the top coat (13) may be a general water-based resin paint such as a vinyl acetate emulsion resin paint or an acrylic emulsion resin paint, but it is assumed that dark particles (14) are added. When the colorant is not added, the top coat (13) may be transparent or translucent, as long as it allows the color of the lower layer that has been overcoated to be seen through. When a colorant is added, the same color as the dark color particles (14) is selected. Since the same color also appears in the gaps (14a) between the particles (14), the shadow of the dark color particles (14) is reflected in the overcoat (13), and a three-dimensional and more effective deep dark color is obtained. As already mentioned, minerals such as silica and transparent particles are not added to the coating for the top coat (13). When added, these have the effect of causing irregular fine irregularities on the surface of the overcoat (13) to erase the gloss and luster of the surface of the coating, but on the other hand, minerals such as silica and transparent particles are dark particles ( This is because the brightness changes due to overlapping with 14), giving a rather dull impression (dull impression, hazy impression, etc.) as a dark color. In the case of a two-coat film structure, it is desirable to add a colorant to the top coat.
濃色粒子(14)は、アクリル樹脂やウレタン樹脂などの硬度のある球形の粒子或いは球形に近い形状、例えばラグビー球状の又は卵状のもので、全体が球面で形成され、角を持たないものが好ましい。 The dark colored particles (14) are hard spherical particles such as acrylic resin and urethane resin, or a shape close to a spherical shape, for example, a rugby spherical shape or an egg-shaped shape, and the whole is formed of a spherical surface and has no corners. Is preferred .
濃色粒子(14)は、中塗り(12)用の塗料(着色剤)と同系統色とする。また、単一色に限らず、黒色に赤色や青色など他の色が混ざっていてもよい。濃色粒子(14)の濃色レベルは、マンセル値の明度で2以下のものを用いるとよい。例えば無彩色(黒色)であればN2以下である。2を超えると望むような深濃色が得られないからである。 The dark particles (14) have the same color as the paint (colorant) for the intermediate coating (12). In addition to the single color, other colors such as red and blue may be mixed with black. The dark color level of the dark particle (14) may be 2 or less in terms of the Munsell value. For example, if the color is achromatic (black), N2 or less. This is because if it exceeds 2, a deep color as desired cannot be obtained.
濃色粒子(14)の直径は20μ〜100μがよく、望ましくは20μ〜40μがよい。20μよりも小さいと上塗り(13)の塗膜に埋没してしまって光の拡散が不十分となり光沢ムラが生じてしまうだけでなく、塗膜の耐傷性に効果が得られない。100μよりも大きいと、粒子(14)間の隙間が大きくなり過ぎると共に凹凸感による光沢が目立って濃色安定性が低下するし、吸音用ピン穴を塞ぎ易くなって吸音性が低下するからである。濃色粒子(14)の直径(即ち、粒子径)はピン穴に比べて十分小さい。(ピン穴直径は0.8〜1.6mm程度である。) The diameter of the dark colored particles (14) is preferably 20 μ to 100 μ, more preferably 20 μ to 40 μ. If it is smaller than 20 μm, it will be buried in the coating film of the top coat (13), resulting in insufficient light diffusion and uneven glossiness, and an effect on the scratch resistance of the coating film will not be obtained. If it is larger than 100μ, the gap between the particles (14) becomes too large and the luster due to the unevenness is conspicuous and the dark color stability is lowered, and the sound absorbing pin hole is easily closed and the sound absorbing property is lowered. is there. The diameter (namely, particle diameter) of the dark color particles (14) is sufficiently smaller than the pin hole. (The pin hole diameter is about 0.8 to 1.6 mm.)
粒子添加量は、上塗り塗料の10〜20重量%とする。10重量%より少ないと密度が疎になって深濃色としては不足となるし、20重量%を超えると吸音用ピン穴を塞ぎ易くなって吸音性能が低下するからである。 The amount of added particles is 10 to 20% by weight of the top coat. If the amount is less than 10% by weight, the density becomes sparse and insufficient as a deep dark color, and if it exceeds 20% by weight, the sound absorbing pin hole is easily blocked and the sound absorbing performance is lowered.
上塗り塗料の粘度はフォードカップ#4で30秒〜50秒程度がよい。また、70〜100g/m2の塗布量で塗布して、塗装膜厚を粒子径より小さい10μ〜18μになるようにして、濃色粒子(14)の表面の一部を覗かせるようにする。70g/m2より少ないと、密度が疎になって深濃色としては不足となるし、100g/m2より多いと乾燥効率が低下すると共に、吸音用ピン穴を塞ぎ易くなって吸音性能が低下するからである。塗布手段は前述同様スプレーコーターやカーテンフローコーターなど既知の手段で構わない。 The viscosity of the top coating is preferably about 30 to 50 seconds for Ford Cup # 4. Further, it is applied at a coating amount of 70 to 100 g / m 2 so that the coating film thickness is 10 μ to 18 μ smaller than the particle diameter so that a part of the surface of the dark colored particles (14) can be seen. . If it is less than 70 g / m 2 , the density becomes sparse and insufficient as a deep dark color, and if it exceeds 100 g / m 2 , the drying efficiency is lowered and the sound absorbing pin hole is easily closed, resulting in sound absorption performance. It is because it falls. The coating means may be a known means such as a spray coater or a curtain flow coater as described above.
本発明では、濃色粒子(14)、水性樹脂塗料に添加される着色料は全て同系統の濃色であって、これらの上記相乗効果により、通常の濃色塗料で塗布した場合(マンセル値の明度2.5〜3.5)に比べて艶のない落ち着いたより深味のある濃色或いは真の濃色が得られ、しかも基材表面の耐傷性を高めることができて施工時に擦り傷や打ち傷を与えたとしても目立たないようにすることが出来る。 In the present invention, the dark color particles (14) and the colorant added to the water-based resin paint are all dark colors of the same system, and due to the above synergistic effect, when applied with a normal dark color paint (Munsell value) Compared to the lightness of 2.5 to 3.5), a darker, darker, deeper dark color or true dark color can be obtained, and the scratch resistance of the substrate surface can be improved, so that scratches and scratches can be caused during construction. Even if it is given, it can be made inconspicuous.
特に、下塗り(11)、中塗り(12)更に上塗り(13)と重ねることによって、繊維への吸い込みムラを解消させて安定しており落ち着いた色艶の外観が得られると共に、濃色粒子(14)は上塗り(13)の塗装膜よりも頭を一部のぞかせた状態で全面的に分布しているので、光を全方向に均等に拡散することができ、光沢ムラのない均一な艶消し外観の深濃色あるいは真濃色が得られる。 In particular, by overlaying the undercoat (11), the intermediate coat (12), and the top coat (13), it is possible to eliminate the unevenness of suction into the fiber and obtain a stable and calm appearance, and dark particles ( 14) is distributed over the entire surface with a part of the head more than the coating film of the top coat (13), so that light can be evenly diffused in all directions, and uniform matte without uneven gloss A deep dark or true dark color can be obtained.
