Definitions
- the present invention relates to a method for coating a heat shielding film that is highly effective in suppressing temperature rise due to radiation such as sunlight and heat transfer, and has excellent durability, and to a heat shielding panel on which the heat shielding film is formed. is there.
- the internal temperature of objects to be painted such as roofs, rooftops, exterior walls, tanks, ships, aircraft, automobiles, trains, work vehicles, special vehicles, helmets, plants, various machines, article covers, storerooms, etc.
- Concrete and metal used as building materials have high thermal conductivity and heat storage, and promote the temperature rise inside the object to be coated.
- Plastic also has high thermal conductivity and heat storage, and promotes temperature rise inside the object to be coated.
- a paint having a coating composition layer (A) and a coating composition layer (B) formed on the coating composition layer (A) on the object to be coated contains a composite metal oxide pigment containing an oxide of Bi and / or Y and an oxide of Mn, and a resin (a), and the coating composition layer (B ) Is a compound represented by the general formula Si (OR) 4 (wherein R may be the same or different and each represents a hydrogen atom or an alkyl group having 1 to 5 carbon atoms) or a partial condensate thereof;
- R may be the same or different and each represents a hydrogen atom or an alkyl group having 1 to 5 carbon atoms
- a heat ray highly reflective coating containing resin (b) has been proposed (see, for example, Patent Document 1).
- Patent Document 1 The technique described in Patent Document 1 is satisfactory by using a fluoroolefin copolymer (for example, Lumiflon manufactured by Asahi Glass Co., Ltd. (registered trademark, hereinafter, description of being a registered trademark is omitted)). It has a weather resistance. Further, Patent Document 1 describes that a hollow spherical body (for example, a shirasu balloon) capable of imparting heat insulation may be included as necessary.

Description
本発明は、太陽光などの輻射や伝熱による温度上昇を高効率で抑制するとともに耐久性に優れた熱遮断膜の塗装方法、及び、その熱遮断膜が形成された遮熱パネルに関するものである。
The present invention relates to a method for coating a heat shielding film that is highly effective in suppressing temperature rise due to radiation such as sunlight and heat transfer, and has excellent durability, and to a heat shielding panel on which the heat shielding film is formed. is there.
太陽光などの照射によって、たとえば屋根や屋上、外壁、タンク、船舶、航空機、自動車、電車、作業車、特殊車両、ヘルメット、プラント、各種機械、物品のカバー、物置などの被塗装物の内部温度の上昇を抑制することは、省エネルギーの観点から近年益々重要性が高まってきている。建築材として使用されるコンクリート及び金属は、熱伝導率及び蓄熱性が高く、被塗装物内部の温度上昇を促進する。また、プラスチックも、熱伝導率及び蓄熱性が高く、被塗装物内部の温度上昇を促進する。なお、木材（木質系のものを含む）は、コンクリートや金属、プラスチックほどではないものの、被塗装物内部の温度が上昇することに変わりはない。
The internal temperature of objects to be painted, such as roofs, rooftops, exterior walls, tanks, ships, aircraft, automobiles, trains, work vehicles, special vehicles, helmets, plants, various machines, article covers, storerooms, etc. In recent years, it has become increasingly important to suppress the rise in energy consumption from the viewpoint of energy saving. Concrete and metal used as building materials have high thermal conductivity and heat storage, and promote the temperature rise inside the object to be coated. Plastic also has high thermal conductivity and heat storage, and promotes temperature rise inside the object to be coated. Although wood (including wood-based ones) is not as strong as concrete, metal, or plastic, the temperature inside the object to be coated remains unchanged.
また、屋外に設置されるタンク（たとえば貯水タンク、石油貯留タンク、穀物用タンク等）の表面は、太陽光などが照射されると、その熱によって温度が上昇し、タンク内部の温度を上昇させ、タンク内外の温度差が拡大する。その結果、タンク内部の物質の品質を変化（劣化）させたり、揮発成分の蒸発によって火災や爆発などの危険な状態を引き起こしたりする可能性が生じる。これらのことから、被塗装物に水をかけて冷却することが実際によく行なわれている。しかしながら、このような冷却の仕方では、水によって被塗装物の錆びを助長してしまうだけでなく、水の消費及びランニングコストの増大に繋がってしまう。
Also, the surface of tanks installed outdoors (for example, water storage tanks, oil storage tanks, grain tanks, etc.), when exposed to sunlight, etc., rises in temperature due to the heat, raising the temperature inside the tank. The temperature difference between the inside and outside of the tank increases. As a result, there is a possibility that the quality of the substance inside the tank is changed (deteriorated) or a dangerous state such as a fire or explosion is caused by evaporation of volatile components. From these facts, it is actually well practiced to cool the object to be coated with water. However, such a cooling method not only promotes rusting of the object to be coated with water, but also leads to an increase in water consumption and running cost.
そこで、被塗装物に遮熱効果を有している熱遮断膜を塗装形成すること技術が種々開示されている。そのようなものとして、「被塗装物上に、塗料組成物層（Ａ）と、該塗料組成物層（Ａ）上に形成された塗料組成物層（Ｂ）とを有する塗装物であって、前記塗料組成物層（Ａ）は、Ｂｉおよび／またはＹの酸化物とＭｎの酸化物とを含む複合金属酸化物顔料と、樹脂（ａ）とを含有し、前記塗料組成物層（Ｂ）は、一般式Ｓｉ（ＯＲ）4 （式中、Ｒは互いに同一でも異なってもよく、水素原子または炭素数１～５のアルキル基を示す。）で表される化合物またはその部分縮合物と、樹脂（ｂ）とを含有する熱線高反射塗装物」が提案されている（たとえば、特許文献１参照）。
Therefore, various techniques for coating a heat shielding film having a heat shielding effect on an object to be coated are disclosed. As such, “a paint having a coating composition layer (A) and a coating composition layer (B) formed on the coating composition layer (A) on the object to be coated; The coating composition layer (A) contains a composite metal oxide pigment containing an oxide of Bi and / or Y and an oxide of Mn, and a resin (a), and the coating composition layer (B ) Is a compound represented by the general formula Si (OR) 4 (wherein R may be the same or different and each represents a hydrogen atom or an alkyl group having 1 to 5 carbon atoms) or a partial condensate thereof; , A heat ray highly reflective coating containing resin (b) has been proposed (see, for example, Patent Document 1).
特許文献１に記載されている技術は、フルオロオレフィン系共重合体（たとえば、旭硝子株式会社製のルミフロン（登録商標、以下登録商標である旨の記載を省略する））を用いることによって、良好な耐候性を有するようにしたものである。また、特許文献１には、断熱性を付与できる中空球状体（たとえばシラスバルーン）を必要に応じて含有させてもよいということが記載されている。しかしながら、特許文献１に記載の技術では、中空球状体を必要に応じて含有させてもよいという記載があるだけで、中空球状体とフルオロオレフィン系共重合体とによる相乗効果についての言及はされていない。
The technique described in Patent Document 1 is satisfactory by using a fluoroolefin copolymer (for example, Lumiflon manufactured by Asahi Glass Co., Ltd. (registered trademark, hereinafter, description of being a registered trademark is omitted)). It has a weather resistance. Further, Patent Document 1 describes that a hollow spherical body (for example, a shirasu balloon) capable of imparting heat insulation may be included as necessary. However, in the technique described in Patent Document 1, there is only a description that a hollow sphere may be included as necessary, and no mention is made of a synergistic effect of the hollow sphere and the fluoroolefin copolymer.

｛ベース材（Ａ）｝
ベース材（Ａ）は、被塗装物の表面上の一部あるいは全部に塗布されるものである。通常、ベース材（Ａ）は、太陽光が照射される面に塗布される。このベース材（Ａ）を、被塗装物の表面に直接塗布してもよく、前処理として塗布されるプライマーや下塗り材等の前処理層を介して塗布してもよい。通常は、前処理層を介してベース材（Ａ）を塗布するのが好ましい。なお、ベース材（Ａ）の塗布量（塗り厚さ）を特に限定するものではないが、１．０ｋｇ／ｍ2 ～２．０ｋｇ／ｍ2 が好ましく、より好ましくは１．６ｋｇ／ｍ2 ～２．０ｋｇ／ｍ2 である。なお、１．０ｋｇ／ｍ2 ～２．０ｋｇ／ｍ2 の範囲でベース材（Ａ）を塗布すると、実際の塗り厚みは０．６ｍｍ～１．２ｍｍ程度となる。 {Base material (A)}
The base material (A) is applied to a part or all of the surface of the object to be coated. Usually, a base material (A) is apply | coated to the surface irradiated with sunlight. This base material (A) may be applied directly to the surface of the object to be coated, or may be applied via a pretreatment layer such as a primer or an undercoat material applied as a pretreatment. Usually, it is preferable to apply the base material (A) through the pretreatment layer. The application amount (coating thickness) of the base material (A) is not particularly limited, but is preferably 1.0 kg / m 2 to 2.0 kg / m 2 , more preferably 1.6 kg / m 2 to 2.0 kg / m 2 . When the base material (A) is applied in the range of 1.0 kg / m 2 to 2.0 kg / m 2 , the actual coating thickness is about 0.6 mm to 1.2 mm.

When the base material (A) is applied in the range of 1.0 kg / m 2 to 2.0 kg / m 2 , the actual coating thickness is about 0.6 mm to 1.2 mm.
ベース材（Ａ）は、６５～７５質量％の火山ガラスを含むシラスバルーンを配合した無機質複合ポリマーである。シラスバルーンは、南九州一帯に多量に存在する火山噴出物である「シラス」を主成分としており、この「シラス」の微粉末を熱処理し、粒子を発泡させたものである。シラスバルーンを構成する微細な風船状の空洞が、熱を伝達しにくくしている。なお、「シラス」は、６５～７５質量％の火山ガラスと、２２～３２質量％の石英・長石と、３質量％の磁鉱物と、の鉱物で組成されている。このベース材（Ａ）としては、株式会社明光建商（日本フェース株式会社）製のシポフェース（商品名）のベース材を使用するとよい。
The base material (A) is an inorganic composite polymer blended with a shirasu balloon containing 65 to 75% by mass of volcanic glass. The Shirasu Balloon contains “Shirasu”, a volcanic eruption present in large quantities in the southern Kyushu region, and the “Shirasu” fine powder is heat treated to foam the particles. The fine balloon-like cavities that make up the Shirasu balloon make it difficult to transfer heat. “Shirasu” is composed of minerals of 65 to 75% by mass of volcanic glass, 22 to 32% by mass of quartz / feldspar, and 3% by mass of magnetic mineral. As this base material (A), it is preferable to use a base material of Shippo Face (trade name) manufactured by Meiko Kensho Co., Ltd. (Nihon Face Co., Ltd.).
シポフェースに用いられているベース材は、遮熱性能及び断熱性能に非常に優れているので、本方法のベース材（Ａ）としては好適である。このシポフェースは、塗膜形成時にアモルファスシリカとセメントとが反応することによって生じるエトリンガイト（針状結晶）が基体の徽細孔まで侵入し、エマルジョンとの相乗効果により強靭な付着力を発揮し、躯体と一体化した塗膜を形成する。したがって、シポフェースのベース材を使用すれば、被塗装物が金属等の表面が固く丈夫なものであっても、エマルジョンとの相乗作用により強固に付着することになる。また、シポフェースのベース材は、防音効果に優れているという性質も有している。
Since the base material used for Shippoface is very excellent in heat shielding performance and heat insulation performance, it is suitable as the base material (A) of this method. This Sipoface has a strong adhesion due to a synergistic effect with the emulsion, in which ettringite (needle crystals) generated by the reaction of amorphous silica and cement during coating formation penetrates into the pores of the substrate. And form an integrated coating. Therefore, if the base material of Shippoface is used, even if the object to be coated has a hard surface such as metal, it adheres firmly due to the synergistic action with the emulsion. Further, the base material of the tip face also has a property of being excellent in soundproofing effect.
｛トップコート（Ｂ）｝
トップコート（Ｂ）は、その一部あるいは全部が水性フッ素樹脂であることが好ましい。それは、水性フッ素樹脂は、紫外線や可視光線を効率良く反射でき、耐候性に優れ、長寿命であり、防汚性が高いという性質を有しており、環境により配慮できるという特性を有しているからである。この水性フッ素樹脂としては、旭硝子株式会社製のルミフロン（ルミフロンの中でも遮熱顔料又は中空ビーズを含んでいるもの）を使用するとよい。また、トップコート（Ｂ）は、ルミフロンの他に、たとえばアルキッド樹脂やアミノアルキッド樹脂、ポリエステル樹脂、エポキシ樹脂、ウレタン樹脂、エポキシポリエステル樹脂、ポリ酢酸ビニル樹脂、アクリル樹脂、塩化ビニル樹脂、フェノール樹脂、シリコーン変性ポリエステル樹脂、アクリルシリコーン樹脂、シリコーン樹脂等を加えてもよい。 {Top coat (B)}
It is preferable that a part or all of the top coat (B) is an aqueous fluororesin. The water-based fluororesin has the properties that it can reflect ultraviolet rays and visible light efficiently, has excellent weather resistance, has a long life, and has high antifouling properties, and can be considered by the environment. Because. As this water-based fluororesin, Lumiflon manufactured by Asahi Glass Co., Ltd. (a Lumiflon containing a heat shielding pigment or hollow beads) may be used. In addition to Lumiflon, the top coat (B) is, for example, alkyd resin, amino alkyd resin, polyester resin, epoxy resin, urethane resin, epoxy polyester resin, polyvinyl acetate resin, acrylic resin, vinyl chloride resin, phenol resin, Silicone-modified polyester resin, acrylic silicone resin, silicone resin and the like may be added.

トップコート（Ｂ）は、水性フッ素樹脂の中でも特に伸び率が高いものを使用するのが望ましい。伸び率が９０％未満である水性フッ素樹脂を使用すると、被塗装物の表面に亀裂が発生することが分かっている。したがって、伸び率が９０％以上、好ましくは１２０％以上である水性フッ素樹脂を使用することが望ましい。また、トップコート（Ｂ）の塗布量（塗り厚さ）を特に限定するものではないが、０．１５ｋｇ／ｍ2 ～０．３ｋｇ／ｍ2 が好ましく、より好ましくは０．２ｋｇ／ｍ2 である。なお、以下で詳述するが、通常トップコートは、プライマーを介して塗布されるが、本方法のトップコート（Ｂ）は、プライマーを介さなくても充分にベース材（Ａ）に密着する。
As the top coat (B), it is desirable to use an aqueous fluororesin having a particularly high elongation rate. It has been found that when an aqueous fluororesin having an elongation of less than 90% is used, cracks occur on the surface of the object to be coated. Therefore, it is desirable to use an aqueous fluororesin having an elongation percentage of 90% or more, preferably 120% or more. Also, but not limited to top coating amount of coating (B) a (coating thickness) in particular, preferably from 0.15kg / m 2 ~ 0.3kg / m 2, more preferably 0.2 kg / m 2 is there. As will be described in detail below, the top coat is usually applied through a primer, but the top coat (B) of this method is sufficiently adhered to the base material (A) without using a primer.
また、水性フッ素樹脂には、遮熱顔料又は中空ビーズが含有されている。遮熱顔料及び中空ビーズは、遮熱性の更なる向上に寄与するものである。遮熱顔料は、たとえばチタン酸バリウムや酸化ジルコニウム、酸化イットリウム、酸化インジウム、酸化マグネシウム、酸化亜鉛、酸化カルシウム、酸化バリウム、酸化セリウムのいずれかを含んで構成されている。つまり、遮熱顔料は、赤外線を選択的に反射する遮熱性の高いもので構成されている。また、遮熱顔料は、水性フッ素樹脂への充填量を多くするために、水性フッ素樹脂よりも比重が小さいことが好ましい。
The water-based fluororesin contains a heat shielding pigment or hollow beads. The heat shielding pigment and the hollow beads contribute to further improvement of the heat shielding property. The heat-shielding pigment includes, for example, any one of barium titanate, zirconium oxide, yttrium oxide, indium oxide, magnesium oxide, zinc oxide, calcium oxide, barium oxide, and cerium oxide. That is, the heat shielding pigment is composed of a highly heat shielding material that selectively reflects infrared rays. In addition, the heat shielding pigment preferably has a specific gravity smaller than that of the aqueous fluororesin in order to increase the filling amount of the aqueous fluororesin.
微小中空球体またはバルーン等と称される中空ビーズは、比重が小さく、断熱性能に優れ、球状体であることから、水性フッ素樹脂への充填量を多くすることができる。中空ビーズとしては、たとえば無機系中空ビーズ（ガラスビーズやシリカビーズ、シラスビーズ、アルミナビーズ、ジルコニアビーズ、アルミノシリケートビーズ等）や、有機系中空ビーズ（塩化ビニリデン樹脂やアクリロニトリル樹脂、メタクリル酸メチル樹脂、フェノール樹脂等）がある。
Hollow beads called micro hollow spheres or balloons have a small specific gravity, are excellent in heat insulation performance, and are spherical, so that the filling amount of the aqueous fluororesin can be increased. Examples of the hollow beads include inorganic hollow beads (glass beads, silica beads, shirasu beads, alumina beads, zirconia beads, aluminosilicate beads, etc.) and organic hollow beads (vinylidene chloride resin, acrylonitrile resin, methyl methacrylate resin, Phenolic resin).
｛プライマー（Ｃ）｝
プライマー（Ｃ）は、ベース材（Ａ）の下地として塗布されるものである。通常、ベース材（Ａ）を被塗装物に塗布する前に被塗装物の表面を前処理する。この前処理としては、たとえばケレンや高圧水洗浄、清掃、研磨、サンダー処理、封孔処理等が挙げられる。ベース材（Ａ）を塗布する前の被塗装物の表面は、汚れている部分があったり、錆びている部分があったり、脆弱化している部分があったりする。このような部分を事前に除去や補修するために前処理が施される。そして、このような前処理を１種又は２種以上施してから、プライマー（Ｃ）を塗布するようになっている。本方法では、必要に応じてプライマー（Ｃ）をベース材（Ａ）の下地として用いることとしている。 {Primer (C)}
The primer (C) is applied as a base of the base material (A). Usually, the surface of the object to be coated is pretreated before the base material (A) is applied to the object to be coated. Examples of this pretreatment include keren and high-pressure water washing, cleaning, polishing, sanding treatment, sealing treatment, and the like. The surface of the object to be coated before applying the base material (A) may have a dirty part, a rusted part, or a weakened part. Pretreatment is performed to remove or repair such a part in advance. And after applying 1 type, or 2 or more types of such pretreatment, the primer (C) is applied.
