図２に示すように、金属パネルの一例としての、アルミ製外壁パネル、ステンレス製外壁パネル等の金属製外壁パネル１は、例えば、鉄骨造（Ｓ造）の建物２の外壁取付下地３（図３参照）に取付けられて建物２の外壁面４を構成する。
金属製外壁パネル１は、例えば、厚さａが数ｃｍ程度、外壁面４を形成する金属面の一辺の長さが１．０ｍ〜１．５ｍ程度の四角形の金属板部５（図３参照）と、金属板部５を外壁取付下地３に取付けるための取付部６（図３参照）とを備えた構成である。取付部６は、例えば、外壁取付下地３に係合する係合部を備え、図外の固定具によって外壁取付下地３に固定される。外壁面４を形成する金属面は金属光沢を有した面に形成されている。
一般的に建物２の外壁面４を形成している金属製外壁パネル１の金属面の光沢は時間が経つにつれて劣化して失われていく。
実施形態による金属製外壁パネルの改修方法を実施することで、建物２の外壁面４を形成している金属製外壁パネル１の劣化した金属面を再生でき、かつ、再生した金属面を保護できる。 As shown in FIG. 2, a metal outer wall panel 1 such as an aluminum outer wall panel or a stainless steel outer wall panel as an example of a metal panel is, for example, an outer wall mounting base 3 (see FIG. 3) to constitute the outer wall surface 4 of the building 2.
The metal outer wall panel 1 has, for example, a rectangular metal plate portion 5 having a thickness a of about several centimeters and a length of one side of the metal surface forming the outer wall surface 4 of about 1.0 m to 1.5 m (see FIG. 3). ) And a mounting portion 6 (see FIG. 3) for mounting the metal plate portion 5 to the outer wall mounting base 3. The mounting portion 6 includes, for example, an engaging portion that engages with the outer wall mounting base 3, and is fixed to the outer wall mounting base 3 by a fixing tool (not shown). The metal surface forming the outer wall surface 4 is formed into a surface having a metallic luster.
In general, the gloss of the metal surface of the metal outer wall panel 1 forming the outer wall surface 4 of the building 2 is deteriorated and lost over time.
By performing the method of repairing a metal outer wall panel according to the embodiment, the deteriorated metal surface of the metal outer wall panel 1 forming the outer wall surface 4 of the building 2 can be regenerated, and the regenerated metal surface can be protected. .

実施形態による金属製外壁パネル１の改修方法は、図１に示すように、洗浄工程Ｓ１と、研磨工程Ｓ２と、紫外線硬化型樹脂塗料塗布工程Ｓ３と、紫外線硬化型樹脂塗料硬化工程Ｓ４と、を含む。
洗浄工程Ｓ１では、建物２の外壁面４を形成している金属光沢が失われた改修対象の金属製外壁パネル１の金属面に洗浄用液体を塗布した後、布やスポンジ等の図外の拭材を用いて金属面を洗浄する。
洗浄工程Ｓ１の洗浄後においては、例えば、図３（ａ）に示すように、外壁面４を形成している金属製外壁パネル１の金属面１２Ａに、酸化部分や点食部分等の劣化部分１０や上記洗浄で除去されなかった付着物１１が残る。
研磨工程Ｓ２では、洗浄後の改修対象の金属製外壁パネル１の金属面１２Ａを研磨剤を用いて研磨することによって、外壁面４を形成している金属製外壁パネル１の金属面１２Ａの酸化部分や点食部分等の劣化部分１０や上記洗浄で除去されなかった付着物１１等を除去して、金属面１２Ａを金属光沢を有した金属面１２に形成する。即ち、金属光沢が失われた金属製外壁パネル１の劣化した金属面１２Ａを研磨して金属光沢を有した金属面１２に再生させる（図３（ｂ）参照）。
このように、金属光沢が失われた金属製外壁パネル１の劣化した金属面１２Ａが、洗浄工程Ｓ１及び研磨工程Ｓ２を経て、金属光沢を有した金属面１２に再生される。
紫外線硬化型樹脂塗料塗布工程Ｓ３では、図３（ｃ）に示すように、遮光手段１３を用いて研磨作業後の金属光沢を有した金属外壁パネル１の金属面１２に太陽光１４が当たらないようにした状態で、金属面１２に紫外線硬化型樹脂塗料１５を塗布する。紫外線硬化型樹脂塗料塗布工程Ｓ３では、金属面１２の金属質感を損なわないようにするために、金属面１２に紫外線硬化型樹脂塗料１５を１μｍ〜２μｍ程度の厚さに塗布する。つまり、通常、紫外線硬化型樹脂塗料は１５μｍ〜２０μｍ程度の厚さに塗布されるが、本発明では、金属面１２の金属質感を損なわないようにするために、紫外線硬化型樹脂塗料１５を、通常の塗布厚さの１／１０程度の厚さで金属面１２に薄く塗るようにしている。このように、金属面１２に均一な薄い厚さの紫外線硬化型樹脂塗料１５の塗膜を形成するためには、例えば、図３（ｃ）に示すような、マイクロファイバー繊維２１に染み込ませた紫外線硬化型樹脂塗料１５を金属面１２に塗布できるような塗装具２０を用いて塗布作業を行えばよい。
紫外線硬化型樹脂塗料硬化工程Ｓ４では、図３（ｄ）に示すように、金属面１２に塗布された紫外線硬化型樹脂塗料１５に太陽光１４が当たらないように遮光手段１３を用いて遮光した状態において、金属面１２に塗布された紫外線硬化型樹脂塗料１５に紫外線照射機１６で紫外線１７を照射して当該紫外線硬化型樹脂塗料１５を硬化させる。
紫外線硬化型樹脂塗料塗布工程Ｓ３及び紫外線硬化型樹脂塗料硬化工程Ｓ４においては、遮光手段１３を用いて金属外壁パネル１の金属面１２に太陽光１４が当たらないようにした状況下で、紫外線硬化型樹脂塗料１５を塗布する作業、紫外線硬化型樹脂塗料１５を硬化させる作業を行うようにしたので、硬化した紫外線硬化型樹脂塗料１５の表面１８の仕上がりに硬化ムラができてしまうようなことを防止でき、品質の良い外壁面４を形成できる。
最後に、金属外壁パネル１の金属面１２に塗布されて硬化した紫外線硬化型樹脂塗料１５の表面１８を洗浄する。
以上説明した金属製外壁パネル１の改修方法により、劣化した金属製外壁パネル１の金属面１２Ａの金属光沢が再生され、かつ、金属光沢の戻った金属製外壁パネル１の金属面１２が硬化した紫外線硬化型樹脂塗料１５によって覆われるので、金属製外壁パネル１の金属面１２が保護され、金属面１２の金属光沢を維持できるとともに金属面１２の劣化を防止できる外壁面４を形成できる。
尚、洗浄工程Ｓ１、研磨工程Ｓ２、紫外線硬化型樹脂塗料塗布工程Ｓ３、紫外線硬化型樹脂塗料硬化工程Ｓ４の一連の工程は、複数枚の金属製外壁パネル１に対してまとめて行うようにすれば効率的に作業を行える。 As shown in FIG. 1, the method of repairing the metal outer wall panel 1 according to the embodiment includes a cleaning step S1, a polishing step S2, an ultraviolet curable resin coating application step S3, an ultraviolet curable resin coating curing step S4, including.
In the cleaning step S1, after applying the cleaning liquid to the metal surface of the metal outer wall panel 1 to be repaired, which has lost the metallic luster that forms the outer wall surface 4 of the building 2, the cloth or sponge is not shown. Clean the metal surface with a wipe.
After cleaning in the cleaning step S1, for example, as shown in FIG. 3A, the metal surface 12A of the metal outer wall panel 1 forming the outer wall surface 4 has deteriorated portions such as oxidized portions and pitting portions. 10 and the deposits 11 that have not been removed by the above cleaning remain.
In the polishing step S2, the metal surface 12A of the metal outer wall panel 1 to be repaired after polishing is polished with an abrasive to oxidize the metal surface 12A of the metal outer wall panel 1 forming the outer wall surface 4. The metal surface 12A is formed on the metal surface 12 having a metallic luster by removing the deteriorated portion 10 such as the portion or the pitting portion or the deposit 11 that has not been removed by the cleaning. That is, the deteriorated metal surface 12A of the metal outer wall panel 1 that has lost its metallic luster is polished and regenerated into the metallic surface 12 having the metallic luster (see FIG. 3B).
Thus, the deteriorated metal surface 12A of the metal outer wall panel 1 that has lost its metallic luster is regenerated into the metallic surface 12 having the metallic luster through the cleaning step S1 and the polishing step S2.
In the ultraviolet curable resin coating application step S3, as shown in FIG. 3C, the sunlight 14 does not hit the metal surface 12 of the metal outer wall panel 1 having a metallic luster after polishing using the light shielding means 13. In such a state, the ultraviolet curable resin coating 15 is applied to the metal surface 12. In the ultraviolet curable resin coating application step S <b> 3, the ultraviolet curable resin coating 15 is applied to the metal surface 12 to a thickness of about 1 μm to 2 μm so as not to impair the metal texture of the metal surface 12. That is, normally, the ultraviolet curable resin coating is applied to a thickness of about 15 μm to 20 μm. However, in the present invention, in order not to impair the metal texture of the metal surface 12, the ultraviolet curable resin coating 15 is The metal surface 12 is thinly coated with a thickness of about 1/10 of the normal coating thickness. Thus, in order to form a coating film of the UV curable resin coating 15 having a uniform thin thickness on the metal surface 12, for example, the microfiber fiber 21 as shown in FIG. What is necessary is just to perform application | coating operation | work using the coating tool 20 which can apply | coat the ultraviolet curable resin coating material 15 to the metal surface 12. FIG.
In the ultraviolet curable resin coating curing step S4, as shown in FIG. 3D, the ultraviolet curable resin coating 15 applied to the metal surface 12 is shielded from light by using the light shielding means 13 so that the sunlight 14 does not hit it. In this state, the ultraviolet curable resin paint 15 applied to the metal surface 12 is irradiated with ultraviolet rays 17 by the ultraviolet irradiator 16 to cure the ultraviolet curable resin paint 15.
In the UV curable resin coating application step S3 and the UV curable resin coating curing step S4, UV curing is performed under the condition that the sunlight 14 does not hit the metal surface 12 of the metal outer wall panel 1 using the light shielding means 13. Since the operation of applying the mold resin coating 15 and the operation of curing the ultraviolet curable resin coating 15 are performed, the surface of the cured ultraviolet curable resin coating 15 may be unevenly cured. The outer wall surface 4 can be formed with good quality.
Finally, the surface 18 of the ultraviolet curable resin coating 15 applied and cured on the metal surface 12 of the metal outer wall panel 1 is washed.
By the repair method of the metal outer wall panel 1 described above, the metallic luster of the metal surface 12A of the deteriorated metal outer wall panel 1 is regenerated, and the metal surface 12 of the metal outer wall panel 1 that has returned to the metallic luster is cured. Since it is covered with the ultraviolet curable resin coating 15, the metal surface 12 of the metal outer wall panel 1 can be protected, and the outer wall surface 4 that can maintain the metallic luster of the metal surface 12 and prevent the metal surface 12 from deteriorating can be formed.
The series of steps of the cleaning step S1, the polishing step S2, the ultraviolet curable resin coating application step S3, and the ultraviolet curable resin coating curing step S4 are performed collectively on the plurality of metal outer wall panels 1. Work efficiently.

研磨剤としては、例えば、粉末剤等を用いればよい。具体的には、粒径１３μｍ程度、粘度２０００〜３０００ｍＰａ・Ｓ（２５℃）程度のシリカ（珪石）を主成分とするシリカ系研磨剤を用いればよい。尚、劣化した金属面１２Ａの状態、例えば、金属面１２Ａの汚れや凹凸を激しい場合には、炭素ケイ素系研磨剤（５μｍ〜１０μｍ）を上記シリカ系研磨剤に添加したものを研磨剤として使用することが好ましい。例えば、シリカ系研磨剤に対して炭素ケイ素系研磨剤（５μｍ〜１０μｍ）をシリカ系研磨剤の総量の３％〜１０％程度添加したものを使用すればよい。
遮光手段としては、例えば、遮光シート等を用いればよい。
紫外線照射機１６としては、例えば、金属製外壁パネル１がアルミ製外壁パネルである場合において、照度２５０ｍｍｗ／ｃｍ２を出力可能な紫外線照射機を用いて紫外線硬化型樹脂塗料１５に１〜２秒照射した。 For example, a neutral detergent or water may be used as the cleaning liquid.
As the abrasive, for example, a powder or the like may be used. Specifically, a silica-based abrasive mainly composed of silica (silica) having a particle diameter of about 13 μm and a viscosity of about 2000 to 3000 mPa · S (25 ° C.) may be used. When the deteriorated state of the metal surface 12A, for example, when the metal surface 12A is heavily soiled or uneven, a material obtained by adding a carbon silicon abrasive (5 μm to 10 μm) to the silica abrasive is used as an abrasive. It is preferable to do. For example, what added carbon silicon type abrasives (5 micrometers-10 micrometers) about 3%-10% of the total amount of silica type abrasives to silica type abrasives should be used.
For example, a light shielding sheet may be used as the light shielding means.
As the ultraviolet irradiator 16, for example, when the metal outer wall panel 1 is an aluminum outer wall panel, an ultraviolet irradiator capable of outputting an illuminance of 250 mmw / cm 2 is used for the ultraviolet curable resin coating 15 for 1 to 2 seconds. Irradiated.

また、紫外線硬化型樹脂塗料塗布工程Ｓ３では、金属面１２に紫外線硬化型樹脂塗料１５を１μｍ〜２μｍ程度の厚さに塗布したので、金属面１２の金属質感を損なわないようにでき、金属面１２を新品に近い状態に再生できるようになる。
また、紫外線硬化型樹脂塗料１５として金属面１２に対して付着性のよいものを用い、かつ、紫外線硬化型樹脂塗料１５が硬化した硬化膜は鉛筆の芯の硬度５Ｈと同等の硬度を持つので、金属光沢を有した耐候性、耐久性に優れた外壁面４を形成できる。
また、紫外線硬化型樹脂塗料１５の硬化時間は数秒程度であるので、工期短縮を図れる。
また、遮光手段１３を用いて金属外壁パネル１の金属面１２に太陽光が当たらないようにした状態で、紫外線硬化型樹脂塗料塗布工程Ｓ３及び紫外線硬化型樹脂塗料硬化工程Ｓ４を実施するので、硬化した紫外線硬化型樹脂塗料１５の表面１８の硬化ムラをなくすことができ、きれいな仕上がりの外壁面４を形成できる。 According to the embodiment, since the cleaning step S1 and the polishing step S2 are performed, the metal surface 12A of the deteriorated metal outer wall panel 1 is regenerated (restored) into a metal surface 12 having a metallic luster having an original design and texture. it can.
Further, since the ultraviolet curable resin coating application step S3 and the ultraviolet curable resin coating curing step S4 are performed, the metal surface 12 of the metal outer wall panel 1 whose metallic luster has returned is covered with the cured ultraviolet curable resin coating 15. Therefore, the metal surface 12 of the metal outer wall panel is protected by the ultraviolet curable resin coating 15, and the outer wall surface 4 that can maintain the metallic luster of the metal surface 12 and prevent the metal surface 12 from being deteriorated can be formed.
Further, in the UV curable resin coating application step S3, since the UV curable resin coating 15 is applied to the metal surface 12 to a thickness of about 1 μm to 2 μm, the metal texture of the metal surface 12 can be kept intact. 12 can be reproduced in a state close to a new one.
In addition, since the ultraviolet curable resin paint 15 having good adhesion to the metal surface 12 is used, and the cured film obtained by curing the ultraviolet curable resin paint 15 has a hardness equivalent to the hardness 5H of the pencil core. The outer wall surface 4 having metallic luster and excellent weather resistance and durability can be formed.
Further, since the curing time of the ultraviolet curable resin coating 15 is about several seconds, the work period can be shortened.
