Abstract
Description
本発明は、塗料および塗装物に関し、特に、防汚性及び遮熱性を兼ね備えた塗料、並びにこれを用いた塗装物に関する。 The present invention relates to a paint and a coated object, and particularly relates to a paint having antifouling properties and heat shielding properties, and a coated object using the same.
近年、工場の折板屋根等の基材としては、例えば、金属製の屋根材料が使用されている。この基材は特に夏場において、その表面温度が70℃程度まで上昇してしまうことがあり、ヒートアイランド現象を引き起こす要因の1つとなっていた。また、基材自体の劣化や接合部の劣化を促進させてしまう要因の1つともなっていた。さらに、建物内の温度も影響を受けて上昇する傾向にあり、特に夏場においては、エネルギー効率が低下してしまう原因となっていた。 In recent years, for example, a metal roof material has been used as a base material such as a folded-plate roof of a factory. The surface temperature of this substrate may rise to about 70 ° C., particularly in summer, and this has been one of the factors that cause the heat island phenomenon. Moreover, it has become one of the factors that promote the deterioration of the base material itself and the deterioration of the joint. Furthermore, the temperature inside the building also tends to increase under the influence, and in the summertime, it has been a cause for energy efficiency to decrease.
従来、上記の問題を解決するために、基材の表面に赤外線を選択的に反射する無機顔料を含有した塗料を塗布する技術がある(例えば、特許文献1参照)。このような塗料を基材の表面に塗布すれば遮熱性が認められるので、上記の問題をある程度は解決することができる。しかし、この塗料を基材に塗布するだけでは、建物等の外壁の汚れを十分に除去することができず、美観性、防汚性に劣ってしまう。 Conventionally, in order to solve the above problem, there is a technique of applying a paint containing an inorganic pigment that selectively reflects infrared rays on the surface of a base material (see, for example, Patent Document 1). If such a paint is applied to the surface of the substrate, the heat shielding property is recognized, so that the above-mentioned problem can be solved to some extent. However, simply applying this paint to the substrate cannot sufficiently remove the dirt on the outer wall of a building or the like, resulting in poor aesthetics and antifouling properties.
一方、建築物の外壁の美観性、防汚性を高める観点から、外壁の汚れ防止技術が利用されている。このような汚れ防止技術としては、例えば、二酸化チタン等の光触媒物質が混合された塗料を外壁表面に塗布し、外壁表面の親水化を進めることにより、外壁表面と汚れの間に雨水等を潜り込ませて、外壁表面の汚れを水で洗い流すものがある(特許文献2参照)。ところが、この技術では遮熱性が十分に認められず、遮熱性を十分なものとするために塗膜厚を厚くすると、コストアップを招いてしまう。
上記のように、従来の塗料は、防汚性、遮熱性のうち一方しか備えておらず、防汚性が認められても遮熱性が認められない、あるいは遮熱性が認められても防汚性が認められないという問題があった。すなわち、防汚性及び遮熱性をともに兼ね備えていないため、上記の問題を十分に解決することができなかった。 As described above, the conventional paint has only one of the antifouling property and the heat shielding property. Even if the antifouling property is recognized, the heat shielding property is not recognized, or the antifouling property is recognized. There was a problem that sex was not recognized. That is, since both the antifouling property and the heat shielding property are not provided, the above problem cannot be solved sufficiently.
そこで、本発明の目的は、防汚性及び遮熱性を兼ね備えた塗料、並びにこれを用いた塗装物を提供することにある。 Then, the objective of this invention is providing the coating material which has antifouling property and heat-insulating property, and the coating material using the same.
上記課題を解決するために、本発明は、基材の表面に塗布または噴霧するための塗料であって、この塗料は光触媒を備えた中空微粒子を含有することとする。このような構成によれば、光触媒(例えば、酸化チタン、酸化亜鉛等)の作用によって防汚性が認められ、さらには中空微粒子の断熱構造によって遮熱性も認められる。 In order to solve the above-described problems, the present invention is a coating for applying or spraying on the surface of a substrate, and the coating contains hollow fine particles provided with a photocatalyst. According to such a configuration, the antifouling property is recognized by the action of a photocatalyst (for example, titanium oxide, zinc oxide, etc.), and further, the heat shielding property is also recognized by the heat insulating structure of the hollow fine particles.
前記中空微粒子は、前記光触媒が中空状の担体に担持されてなり、あるいは前記光触媒が中空状に成形されてなるものが好ましく、その他の形態であってもよい。また、前記中空微粒子は、前記塗料よりも比重が小さく、さらにサイズが1〜350μmであって、前記塗料に対する容積率で1〜100%含まれていることが好ましい。中空微粒子の比重が塗料よりも小さい場合には、塗料の表面に中空微粒子が担持されるので、防汚性及び遮熱性の点で優れている。なお、中空微粒子のサイズ(例えば、粒径等)が1μm未満の場合には遮熱性が不十分となり、他方、350μmを超える場合には塗料に均一的に混入させることが困難となる。また、容積率が1%未満の場合には防汚性が不十分となってしまう。 The hollow fine particles preferably have the photocatalyst supported on a hollow carrier or the photocatalyst formed into a hollow shape, and may have other forms. The hollow fine particles preferably have a specific gravity smaller than that of the paint, and further have a size of 1 to 350 μm, and are contained in an amount of 1 to 100% in terms of the volume ratio with respect to the paint. When the specific gravity of the hollow fine particles is smaller than that of the paint, the hollow fine particles are supported on the surface of the paint, which is excellent in terms of antifouling properties and heat shielding properties. When the size (for example, particle size) of the hollow fine particles is less than 1 μm, the heat shielding property is insufficient. On the other hand, when the size exceeds 350 μm, it is difficult to uniformly mix in the paint. Further, when the volume ratio is less than 1%, the antifouling property is insufficient.
さらに、前記塗料が有機樹脂系塗料を含んで構成されている場合には、前記中空微粒子としては、特にマスクメロン型の中空微粒子が好ましい。マスクメロン型の中空微粒子とは、多孔質状に成形された中空微粒子の表面に前記光触媒を担持させたものであり、例えば、中空微粒子の表面を多孔質状に加工し、あるいは表面が多孔質となるように中空微粒子を製造し、その多孔質内に光触媒を担持させたものがある。もちろん、前記塗料が無機樹脂系塗料を含んで構成されている場合にも、マスクメロン型の中空微粒子を用いてもよい。なお、前記有機樹脂系塗料は、フッ素樹脂系、アクリルシリコン系樹脂、ウレタン系樹脂、変性ウレタン系樹脂、アクリル系樹脂、変性アクリル系樹脂、エポキシ系樹脂、変性エポキシ樹脂系、ポリエステル樹脂系のうち少なくともいずれかを含んで構成されることとしてもよい。また、前記無機樹脂系塗料は、ポリシラザン、ポリシラザン以外の窒化ケイ素樹脂系、セラミック樹脂系のうち少なくともいずれかを含んで構成されることとしてもよい。 Furthermore, when the coating material includes an organic resin-based coating material, the hollow fine particles are particularly preferably mask melon type hollow fine particles. The mask melon type hollow fine particles are those in which the photocatalyst is supported on the surface of a hollow fine particle formed into a porous shape. For example, the surface of the hollow fine particle is processed into a porous shape, or the surface is porous. There are those in which hollow fine particles are produced so that a photocatalyst is supported in the porous material. Of course, the mask melon type hollow fine particles may also be used when the coating material includes an inorganic resin coating material. The organic resin-based paint is a fluororesin-based, acrylic silicon-based resin, urethane-based resin, modified urethane-based resin, acrylic-based resin, modified acrylic-based resin, epoxy-based resin, modified epoxy-resin-based, or polyester resin-based. It may be configured to include at least one of them. The inorganic resin-based paint may include at least one of polysilazane, a silicon nitride resin system other than polysilazane, and a ceramic resin system.
また、本発明は、基材の表面に塗布または噴霧するための塗料であって、この塗料は前記中空微粒子とともに、赤外線を選択的に反射する無機顔料を含有させてなることとしてもよい。このような構成によれば、中空微粒子の断熱構造のみならず、無機顔料の赤外線反射作用も遮熱性の向上に寄与するのでより優れた効果を奏する。 Further, the present invention is a paint for applying or spraying on the surface of a substrate, and this paint may contain an inorganic pigment that selectively reflects infrared rays together with the hollow fine particles. According to such a configuration, not only the heat insulating structure of the hollow fine particles but also the infrared reflecting action of the inorganic pigment contributes to the improvement of the heat shielding properties, so that a more excellent effect is achieved.
前記無機顔料は、チタン酸バリウム、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、酸化セリウムのうち少なくともいずれかを含んで構成されることとしてもよい。また、前記無機顔料は、前記塗料よりも比重が小さく、さらにサイズ(例えば、粒径等)が1〜100μmであって、前記塗料に対する重量率で2〜80%含まれていることが好ましい。無機顔料の比重が塗料よりも小さい場合には、塗料の表面に無機顔料が担持されるので、遮熱性の点で優れている。さらに、無機顔料のサイズが1μm未満の場合には遮熱性が不十分となり、他方、100μmを超える場合には塗料に均一的に混入させることが困難となる。また、重量率が2%未満の場合には遮熱性が不十分となり、他方、80%を越えてしまう場合にはコスト面で好ましくない。また、前記無機顔料は、その表面が光触媒でコーティングされていることとしてもよい。この場合には、無機顔料は遮熱性のみならず、防汚性をも兼ね備えているので好ましい。 The inorganic pigment may include at least one of barium titanate, zirconium oxide, yttrium oxide, indium oxide, magnesium oxide, zinc oxide, calcium oxide, barium oxide, and cerium oxide. The inorganic pigment preferably has a specific gravity smaller than that of the coating material, and further has a size (for example, particle size) of 1 to 100 μm and is contained in an amount of 2 to 80% by weight with respect to the coating material. When the specific gravity of the inorganic pigment is smaller than that of the paint, the inorganic pigment is supported on the surface of the paint, which is excellent in terms of heat shielding properties. Further, when the size of the inorganic pigment is less than 1 μm, the heat shielding property is insufficient, and when it exceeds 100 μm, it is difficult to uniformly mix it with the paint. On the other hand, when the weight percentage is less than 2%, the heat shielding property is insufficient, and when it exceeds 80%, it is not preferable in terms of cost. The surface of the inorganic pigment may be coated with a photocatalyst. In this case, the inorganic pigment is preferable because it has not only a heat shielding property but also an antifouling property.
また、本発明は、基材の表面に塗布または噴霧するための塗料であって、この塗料は光触媒でコーティングされた、赤外線を選択的に反射する無機顔料を含有することとしてもよい。このような構成の場合にも、光触媒の作用によって防汚性が認められ、さらには無機顔料の赤外線反射作用によって遮熱性も認められる。また、この塗料を基材の表面に塗布または噴霧して得られる塗装物も防汚性及び遮熱性を兼ね備える。さらに、この塗料は、前記無機顔料とともに、光触媒を備えていない中空微粒子を含有させてなることとしてもよい。この場合にも中空微粒子の断熱構造が遮熱性の向上に寄与する。また、この塗料は、前記無機顔料とともに、光触媒でコーティングされていないが赤外線を選択的に反射する無機顔料を含有させてなることとしてもよい。この場合にも無機顔料の赤外線反射作用が遮熱性の向上に寄与する。 Further, the present invention is a paint for applying or spraying on the surface of a substrate, and this paint may contain an inorganic pigment that selectively coats infrared rays and is coated with a photocatalyst. Even in such a configuration, the antifouling property is recognized by the action of the photocatalyst, and further, the heat shielding property is recognized by the infrared reflecting action of the inorganic pigment. In addition, a coated product obtained by applying or spraying the paint onto the surface of the substrate also has antifouling properties and heat shielding properties. Further, the coating material may contain hollow fine particles not provided with a photocatalyst together with the inorganic pigment. Also in this case, the heat insulating structure of the hollow fine particles contributes to the improvement of the heat shielding property. In addition to the inorganic pigment, this paint may contain an inorganic pigment that is not coated with a photocatalyst but selectively reflects infrared rays. Also in this case, the infrared reflecting action of the inorganic pigment contributes to the improvement of the heat shielding property.
また、本発明は、屋根材、外装材、内装材、建築物等の基材の表面に、前記塗料を塗布または噴霧してなることとする。このようにして得られる塗装物は、防汚性及び遮熱性を兼ね備える。なお、基材の表面に塗料を塗布する場合には、例えば、吹付けや、ローラー、刷毛、鏝等により行うことができる。また、塗料と基材との間には、基材の材質や表面状態等に応じて、シーラーやフィラー等を適宜介在させてもよい。 Moreover, this invention shall apply | coat or spray the said coating material on the surface of base materials, such as a roofing material, an exterior material, an interior material, and a building. The coated material thus obtained has both antifouling properties and heat shielding properties. In addition, when apply | coating a coating material on the surface of a base material, it can carry out by spraying, a roller, a brush, a scissors etc., for example. Further, a sealer, a filler, or the like may be appropriately interposed between the paint and the base material depending on the material and surface state of the base material.
本発明によれば、塗料及び塗装物は、防汚性及び遮熱性を兼ね備えることができる。 According to the present invention, the paint and the coated product can have both antifouling properties and heat shielding properties.
以下、添付図面を参照しながら、本発明に係る塗料及び塗装物について説明する。
図1は、本発明の一実施形態に係る塗装物を説明するための概略断面図である。図1に示すように塗装物10は、塗料1と、基材3とから構成されている。
Hereinafter, the paint and the coated material according to the present invention will be described with reference to the accompanying drawings.
FIG. 1 is a schematic cross-sectional view for explaining a coated object according to an embodiment of the present invention. As shown in FIG. 1, the coated object 10 includes a paint 1 and a base material 3.
塗料1は、屋根材等の基材3の表面をコーティングするための塗料1であって、赤外線を選択的に反射する無機顔料4(以下、単に「無機顔料」という)と、光触媒を備えた中空微粒子5(以下、単に「中空微粒子」という)とを含有する。そして、この塗料1を基材3の表面に塗布または噴霧して得られる塗装物10は、防汚性及び遮熱性をともに兼ね備えている。 The paint 1 is a paint 1 for coating the surface of a base material 3 such as a roofing material, and includes an inorganic pigment 4 (hereinafter simply referred to as “inorganic pigment”) that selectively reflects infrared rays, and a photocatalyst. It contains hollow fine particles 5 (hereinafter simply referred to as “hollow fine particles”). And the coated object 10 obtained by apply | coating or spraying this coating material 1 on the surface of the base material 3 has both antifouling property and heat-insulating property.
基材3は、塗料1を塗布または噴霧する対象物であり、例えば、屋根材、外装材、内装材、建築物等があり、さらには、コンクリートやプレキャストコンクリート等もある。基材3としては、塗料1を塗布または噴霧した際に基材3の表面に定着し得るものであればよく、特に限定されるものではない。但し、屋根材等のように防汚性または遮熱性の低い基材3を対象とすれば効果的である。 The base material 3 is an object to which the paint 1 is applied or sprayed, and includes, for example, a roofing material, an exterior material, an interior material, a building, and the like, and also concrete, precast concrete, and the like. The substrate 3 is not particularly limited as long as it can be fixed to the surface of the substrate 3 when the coating 1 is applied or sprayed. However, it is effective if the base material 3 having a low antifouling property or heat shielding property such as a roofing material is targeted.
無機顔料4は、赤外線を選択的に反射する遮熱性の高い顔料であって、酸化チタン(ルチル型;チタンホワイト)、酸化第二鉄(赤色)、水酸化鉄(黄色)、酸化クロム(緑色)等の無機元素の酸化物を含んで構成されている。無機顔料4としては、遮熱性に優れたものが好ましく、特に、チタン酸バリウム、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、酸化セリウムのうち少なくともいずれかを含んで構成されることが好ましい。また、無機顔料4は、塗料1よりも比重が小さいことが好ましい。かかる場合には、塗料1を基材3の表面に塗布した際に無機顔料4が表面側に担持されるため、無機顔料4と外気との接触面積が増大し、高い遮熱性を発揮する。さらに、無機顔料4は、サイズ(以下、粒径で表示する)が1〜100μmであって、塗料1に対する重量率で2〜80%含まれていることが好ましい。かかる場合には、より高い遮熱性を発揮することとなる。 The inorganic pigment 4 is a highly heat-shielding pigment that selectively reflects infrared rays. Titanium oxide (rutile type; titanium white), ferric oxide (red), iron hydroxide (yellow), chromium oxide (green) ) And the like. As the inorganic pigment 4, those having excellent heat shielding properties are preferable, and in particular, at least one of barium titanate, zirconium oxide, yttrium oxide, indium oxide, magnesium oxide, zinc oxide, calcium oxide, barium oxide, and cerium oxide is used. It is preferable to be included. The inorganic pigment 4 preferably has a specific gravity smaller than that of the paint 1. In such a case, since the inorganic pigment 4 is supported on the surface side when the coating material 1 is applied to the surface of the substrate 3, the contact area between the inorganic pigment 4 and the outside air is increased, and high heat shielding properties are exhibited. Furthermore, the inorganic pigment 4 is preferably 1 to 100 μm in size (hereinafter expressed as a particle size), and preferably 2 to 80% by weight with respect to the paint 1. In such a case, higher heat shielding properties are exhibited.
一方、中空微粒子5は、酸化チタンや酸化亜鉛等の光触媒を備えており、特に、光触媒が中空状の担体に担持されてなり(例えば、光触媒ガラスビーズ「BL2.5シリーズ」:株式会社光触媒研究所製)、あるいは光触媒が中空状に成形されてなるものが好ましい。また、中空微粒子5は、塗料1よりも比重が小さいことが好ましい。かかる場合には、塗料1を基材3の表面に塗布した際に中空微粒子5が表面側に担持されるため、中空微粒子5と外気との接触面積が増大し、高い防汚染性を発揮する。さらに、中空微粒子5は、サイズ(以下、粒径で表示する)が1〜350μmであって、塗料1に対する容積率で1〜100%含まれていることが好ましい。かかる場合には、より高い防汚性を発揮することとなる。なお、中空微粒子5は、その中空領域が断熱機能を有するので、遮熱性の向上にも寄与する。さらに、光触媒にはその表面に付着した少量の水分を超親水性に変え、気化熱によって表面温度を下げる作用がある。従って、光触媒を備えた中空微粒子5は、それ自体で遮熱効果をも発揮する。なお、光触媒には、空気中に含まれるSOx、NOx等の有害ガス成分を分解する作用があるので、これらの塗料1及び塗装物10は環境浄化にも寄与する。 On the other hand, the hollow fine particles 5 are provided with a photocatalyst such as titanium oxide or zinc oxide. In particular, the photocatalyst is supported on a hollow carrier (for example, photocatalyst glass beads “BL2.5 series”: Photocatalytic Research Co., Ltd.). Manufactured by the company) or a photocatalyst formed into a hollow shape is preferable. The hollow fine particles 5 preferably have a specific gravity smaller than that of the paint 1. In such a case, since the hollow fine particles 5 are supported on the surface side when the coating material 1 is applied to the surface of the substrate 3, the contact area between the hollow fine particles 5 and the outside air is increased, and high antifouling properties are exhibited. . Furthermore, it is preferable that the hollow fine particles 5 have a size (hereinafter referred to as a particle size) of 1 to 350 μm and are contained in an amount of 1 to 100% with respect to the paint 1. In such a case, higher antifouling properties will be exhibited. In addition, since the hollow area | region has the heat insulation function, the hollow microparticle 5 also contributes to the improvement of heat-insulating property. Furthermore, the photocatalyst has the effect of changing a small amount of water adhering to the surface to super hydrophilicity and lowering the surface temperature by heat of vaporization. Therefore, the hollow fine particles 5 provided with the photocatalyst exhibit a heat shielding effect by themselves. In addition, since the photocatalyst has an action of decomposing harmful gas components such as SOx and NOx contained in the air, the paint 1 and the coated object 10 also contribute to environmental purification.
特に、塗料1が有機樹脂系塗料を含んで構成されている場合には、中空微粒子5としては、マスクメロン型の中空微粒子5(但し、上記の中空微粒子5と同一符号を付している)を用いることが好ましい(例えば、マスクメロン型光触媒:株式会社明成商会製)。このマスクメロン型の中空微粒子5とは、多孔質状に成形された中空微粒子の表面に光触媒が担持されたものであり、例えば、中空微粒子の表面を多孔質状に加工し、あるいは表面が多孔質となるように中空微粒子を製造し、その多孔質内に光触媒が担持されたものがある。これにより、光触媒による分解作用を維持確保しつつ、塗料1を構成する有機樹脂系塗料が光触媒によって分解されてしまうことを防ぐことができる。その結果、塗料1の耐久性が維持向上する。なお、有機樹脂系塗料としては、例えば、フッ素樹脂系、アクリルシリコン系樹脂、ウレタン系樹脂、変性ウレタン系樹脂、アクリル系樹脂、変性アクリル系樹脂、エポキシ系樹脂、変性エポキシ樹脂系、ポリエステル樹脂系等がある。 In particular, when the coating material 1 includes an organic resin-based paint, the hollow fine particles 5 may be mask melon type hollow fine particles 5 (however, the same reference numerals as those of the hollow fine particles 5 are given). Is preferable (for example, a mask melon type photocatalyst: manufactured by Meisei Shokai Co., Ltd.). The mask melon type hollow fine particles 5 are those in which a photocatalyst is supported on the surface of a hollow fine particle formed into a porous shape. For example, the surface of the hollow fine particle is processed into a porous shape, or the surface is porous. Some hollow microparticles are produced so as to have a quality, and a photocatalyst is supported in the porous material. Thereby, it can prevent that the organic resin-type coating material which comprises the coating material 1 is decomposed | disassembled by a photocatalyst, maintaining and ensuring the decomposition effect by a photocatalyst. As a result, the durability of the paint 1 is maintained and improved. Examples of organic resin coatings include fluorine resin, acrylic silicon resin, urethane resin, modified urethane resin, acrylic resin, modified acrylic resin, epoxy resin, modified epoxy resin, and polyester resin. Etc.
なお、塗料1は、無機樹脂系塗料を含んで構成されていてもよい。無機樹脂系塗料としては、例えば、ポリシラザン、ポリシラザン以外の窒化ケイ素樹脂系、セラミック樹脂系等がある。この場合、無機樹脂系塗料は光触媒の影響を受けず分解され難いので、マスクメロン型の中空微粒子5を使用する必要はない。特に、常温硬化型でガラス質であるポリシラザンを用いた場合には、ポリシラザンからなる塗料1が基材3に塗布されて硬化し塗膜化すると、比較的初期の段階からその表面が親水化するため、汚れ防止効果が迅速に発揮されるという利点がある。また、塗膜化した際に、表面が高硬度となるため、塗膜内に汚れ粒子等が入り込みにくく、この点からも防汚性に優れている。 In addition, the coating material 1 may be comprised including the inorganic resin type coating material. Examples of the inorganic resin paint include polysilazane, silicon nitride resin other than polysilazane, and ceramic resin. In this case, the inorganic resin-based paint is not affected by the photocatalyst and is not easily decomposed. Therefore, it is not necessary to use the mask melon type hollow fine particles 5. In particular, when polysilazane which is a room temperature curable glassy material is used, when the coating material 1 made of polysilazane is applied to the base material 3 and cured to form a coating film, the surface becomes hydrophilic from a relatively early stage. Therefore, there is an advantage that the antifouling effect can be exhibited quickly. Moreover, since the surface becomes high hardness when it is made into a coating film, dirt particles and the like are difficult to enter into the coating film, and from this point, the antifouling property is excellent.
以上のような塗料1を基材3の表面に塗布または噴霧することにより、屋根材等の基材3の表面はコーティングされ、防汚性及び遮熱性の双方を兼ね備えたものとなる。すなわち、本実施形態によれば、中空微粒子5の光触媒作用による防汚効果と、無機顔料4の赤外線反射作用及び中空微粒子5の断熱構造による遮熱効果とが認められる。また、光触媒により環境中の有害ガスやNOx等を浄化させ、さらには紫外線反射により基材3の劣化を防止することもできる。よって、塗装物10の耐久性を向上させることも可能となる。 By applying or spraying the coating material 1 on the surface of the base material 3 as described above, the surface of the base material 3 such as a roofing material is coated, and both the antifouling property and the heat shielding property are provided. That is, according to the present embodiment, an antifouling effect due to the photocatalytic action of the hollow fine particles 5, an infrared reflection effect of the inorganic pigment 4 and a heat shielding effect due to the heat insulating structure of the hollow fine particles 5 are recognized. In addition, harmful gases, NOx, and the like in the environment can be purified by the photocatalyst, and further, the base material 3 can be prevented from being deteriorated by ultraviolet reflection. Therefore, it becomes possible to improve the durability of the coated object 10.
なお、本実施形態の説明は、本発明の理解を容易にするためのものであり、本発明を限定するものではない。本発明はその趣旨を逸脱することなく、変更、改良され得るとともに本発明にはその等価物が含まれることは勿論である。 Note that the description of the present embodiment is intended to facilitate understanding of the present invention and does not limit the present invention. The present invention can be changed and improved without departing from the gist thereof, and the present invention includes the equivalents thereof.
例えば、無機顔料として、光触媒でコーティングさせていない無機顔料4を例に挙げているが、光触媒でコーティングさせたものを用いてもよい。この場合、無機顔料4の代用としてもよく、あるいは無機顔料4と併用してもよい。また、中空微粒子として、光触媒を備えた中空微粒子5を例に挙げて説明しているが、光触媒でコーティングされた無機顔料を用いる場合には、光触媒を備えていない中空微粒子を用いてもよい。いずれの場合にも塗料1及び塗装物10は、防汚性及び遮熱性を兼ね備えたものとなる。 For example, although the inorganic pigment 4 not coated with a photocatalyst is taken as an example of the inorganic pigment, a pigment coated with a photocatalyst may be used. In this case, the inorganic pigment 4 may be substituted or used in combination with the inorganic pigment 4. In addition, the hollow fine particles 5 provided with the photocatalyst are described as an example of the hollow fine particles. However, when using an inorganic pigment coated with the photocatalyst, hollow fine particles not provided with the photocatalyst may be used. In any case, the paint 1 and the coated object 10 have both antifouling properties and heat shielding properties.
