Specifically, it has a photocatalytic activity over a long period of time by having a film having at least two layers consisting of a substance having photocatalytic activity and an inorganic-organic composite resin that is less deteriorated by the photocatalyst, and also has good weather resistance.
- the present invention relates to an excellent surface-treated precoated metal sheet and a method for producing the same. Further, the present invention relates to a surface treatment liquid for suitably producing the surface-treated precoated metal plate.
- Metal materials typified by iron are generally used by painting for the purpose of improving durability or for obtaining a beautiful appearance.
- the photocatalytic technology is a technology that uses the photocatalytic activity of the photocatalyst particles to make the surface hydrophilic, and a technology that decomposes and removes pollutants centering on organic substances.
- Surface-treated metals have excellent photocatalytic activity. By dispersing and including the particles in the surface film, contamination resistance and a self-cleaning effect are expected. With this technology, it is possible to obtain an excellent effect on the decomposition and removal of contaminants on the surface.
- the photocatalyst particles are dispersed in an organic resin-based coating film, or the photocatalytic coating film is an organic resin-based coating film. When formed on the surface, the organic resin-based coating film gradually decomposes due to the photocatalytic effect, and the deterioration proceeds, so that it was difficult to use for a long period of time.
- Patent Documents 1 and 2 disclose a method using an inorganic component as a resin constituting the film. Further, among organic resins, a fluororesin is relatively stable with respect to a photocatalyst, and therefore a method of using this as a film component has been disclosed (Patent Document 3). In particular, for pre-coated metals, high stability and processability with respect to photocatalysts are required. For this purpose, a method using a silica-organosilane system as a coating component is an acrylic resin and an organo resin.
- Patent Document 4 Methods using alkyl silicate obtained by polymerization reaction with alkoxysilane as a film component are disclosed in Patent Document 4 and Patent Document 5, respectively. Further, Patent Document 6 discloses a method using a vinylidene fluoride resin and an acrylic resin.
- the inventors have also proposed coating resin components that satisfy a high level of photocatalysts that can be used for pre-coated metals, that is, excellent weather resistance and workability (Patent Documents 7 to 9). .
- Japanese Patent Laid-Open No. 07-113272 Japanese Patent Laid-Open No. 08-164334 Japanese Patent Laid-Open No. 07-171408 JP-A-10-225658 JP 2000-317393 A JP 2000-063733 A JP 2006-192716 A JP 2006-192717 A JP 2007-268761 A
- the film is deteriorated by photocatalyst and sunlight, and choking (chalking) occurs. It will wear out.
- the post-coating method has been the mainstream method for forming the photocatalytic film. Therefore, after processing a metal material into the shape of the final product, and for building materials and outdoor structures, it is common to form a photocatalytic film at the time of construction on site.
- the coating is applied after the shape of the final product is applied, or the coating is performed locally, so there are no restrictions on the resin that forms the coating, the coating thickness, etc. It was possible to form a film. However, with pre-coated metal that has been pre-painted and shipped in a state of use by customers, it is difficult to form a film with a certain thickness or more from the viewpoint of processability restrictions and cost, and within this limitation, There has been a demand for a pre-coated metal plate that can maintain stain resistance and self-cleaning properties for a long period of time.
- the present invention has been made to solve this problem, and can maintain the anti-contamination resistance and the self-cleaning function over a long period of time in the presence of restrictions such as the film thickness.
- a surface-treated precoated metal sheet is provided. It is another object of the present invention to provide a method and a surface treatment liquid for suitably producing the surface-treated precoated metal plate.
- a film in which a substance having a photocatalytic activity is blended with at least two layers of an inorganic-organic composite resin on the surface of a precoated metal plate having an organic resin coating layer ( The present inventors have found that the problem can be solved by a surface-treated precoated metal plate having a photocatalytic film) and have completed the present invention. Specifically, in the past, a photocatalyst was added to the protective layer provided between the photocatalyst film and the organic resin film to protect the organic resin film under the photocatalyst film, thereby protecting the organic resin.
- the present invention is as follows.
- a surface-treated precoated metal plate in which at least two layers of a film having photocatalytic activity are formed on a base metal plate and a precoated metal plate having an organic resin coating layer on the surface thereof, and the at least two layers of the film Are alkoxysilanes having an organic group selected from the group consisting of alkyl groups having 1 to 12 carbon atoms, aryl groups, carboxyl groups, hydroxyl groups, and combinations thereof, alkoxysilanes having epoxy groups, alkoxy having amino groups
- a substance having an inorganic-organic composite resin composed of a condensate of an alkoxysilane selected from the group consisting of silane, tetraalkoxysilane, and combinations thereof, and having the photocatalytic activity is the most in the outermost layer film.
- Pre-coated metal plate (2) The surface-treated precoated metal sheet according to (1), wherein the organic group contained in the inorganic-organic composite resin is a methyl group or a phenyl group. (3) The surface-treated precoated metal according to (1) or (2), wherein the content of the substance having photocatalytic activity in each layer of the coating is 0.05% to 50% of the total mass of each layer. Board. (4) The content of the photocatalytic substance in the innermost layer-side film in contact with the organic resin coating layer is 0.05% to 30% by mass ratio with respect to the entire innermost layer film. The surface-treated precoated metal sheet described.
- the base metal plate is selected from a steel plate, a stainless steel plate, a titanium plate, a titanium alloy plate, an aluminum plate, an aluminum alloy plate, or a plated metal plate plated on these metal plates.
- a surface treatment liquid comprising an inorganic-organic composite resin material containing a3) and a substance having photocatalytic activity.
- a method for producing a surface-treated precoated metal sheet wherein the surface treatment liquid according to (7) is applied to a precoated metal sheet having an organic resin coating layer and cured.
- a plurality of the surface treatment liquids according to (7) having different photocatalytic activity contents are simultaneously applied to a pre-coated metal plate having an organic resin coating layer, and then simultaneously dried and baked to form the organic resin coating.
- the present invention it is possible to easily obtain a surface-treated precoated metal sheet that can maintain and continue the contamination resistance due to the photocatalyst and the self-cleaning function over a long period of time.
- said surface treatment precoat metal plate can be suitably manufactured by using the manufacturing method and surface treatment liquid of this invention.
- the precoated metal plate having excellent stain resistance according to the present invention is a further coated film exhibiting stain resistance on a painted surface of a general precoated metal plate, which is a product in which the surface of the metal plate is coated. It is the precoat metal plate which provided the layer of.
- the appearance of contamination resistance due to the further paint film layer is due to the fact that the layer contains a substance (photocatalytic substance) having a photocatalytic activity that exhibits an excellent effect on the decomposition and removal of contaminants on the surface. To do.
- a precoated metal plate having a layer structure in which an additional coating film layer that contributes to contamination resistance by including a photocatalytic substance is provided on the painted surface of a precoated metal plate has been known.
- the coating layer containing the photocatalytic substance is in contact with the coating layer of the precoated metal plate generally formed of an organic resin material, and the photocatalytic effect of the photocatalytic substance causes the underlying precoated metal plate to Since the coating layer gradually decomposes and deteriorates, it is difficult to use it for a long time.
- a protective layer not containing a photocatalytic substance has been interposed between a film layer containing a photocatalytic substance and a lower organic resin coating layer.
- the photocatalyst layer and the protective layer are generally composed mainly of an inorganic component in order to ensure photocatalytic resistance.
- the film thickness should be a certain level or more. Is difficult. For this reason, this method has the disadvantage that the photocatalyst layer has to be thinned by an amount corresponding to the formation of the protective layer film, and the contamination resistance and the self-cleaning property are shortened.
- the present invention adds a photocatalyst less than the content of the upper photocatalytic substance to the protective layer that has been used for the purpose of avoiding direct contact between the film layer containing the photocatalytic substance and the lower organic resin coating layer.
- a layer (photocatalyst layer) containing a photocatalyst material is directly provided on the organic resin coating layer, and (2) a photocatalytic material on the organic resin coating layer.
- the pre-coated metal plate has been successfully maintained in the stain resistance (for example, compared with Example 8).
- the duration of the contamination resistance effect of Example 1 is about 9 years and about 2 years, respectively (see “Self-cleaning duration” in Table 1).
- the present invention aims to avoid the direct contact of the photocatalytic substance with the aim of avoiding the photocatalytic effect of the coating layer containing the photocatalytic substance to reach the lower organic resin coating layer.
- Pre-coated metal sheets that are shipped in a painted state and are processed without requiring painting by customers are limited by the overall coating thickness from the viewpoint of workability. According to the present invention, which can extend the duration of the stain resistance effect as compared with the prior art, it is possible to provide a precoated metal sheet having a more excellent stain resistance effect within the limit of the coating film thickness. Is possible.
- the reason why the contamination resistance effect of the present invention is extended can be considered as follows. So far, as described above, as a typical coating composition of the pre-coated metal plate exhibiting the anti-contamination function due to the photocatalytic effect, (1) a photocatalytic layer directly on the organic resin-based coating layer of the pre-coated metal plate, as described above. What provided and (2) what provided the protective layer between the organic resin-type coating-film layer and photocatalyst layer of a precoat metal plate are known.
- the photocatalyst layer deteriorates due to its own photocatalytic action, and as a result, the period A until the photocatalyst layer disappears due to depletion, and the surface of the organic resin coating on the precoated metal plate in contact with the photocatalyst layer is the photocatalyst.
- the photocatalyst layer is in direct contact with the organic resin coating layer of the base material (in this case, the pre-coated metal plate composed of the base metal plate and the organic resin coating layer formed on the surface).
- the period B1 until the surface of the organic resin coating film deteriorates due to the photocatalytic effect is shorter than the period A1 until the deteriorated photocatalyst layer disappears due to wear, and the relationship of A1> B1 It has become.
- the period B2 until the surface of the organic resin coating is deteriorated by the photocatalytic effect is a period until the deteriorated photocatalytic layer disappears due to wear. Compared with the period A2, it is much longer and the relationship A2 ⁇ B2. For this reason, the contamination resistance by the photocatalyst and the duration of the self-cleaning function are governed by B1 in the case of (1) and A2 in the case of (2).
- the photocatalyst is also added to the conventional protective layer film, it is possible to satisfy A3 ⁇ B3 by adjusting the photocatalyst addition amount and the film thickness (where A3 is deteriorated).
- B3 is a period until the photocatalyst layer disappears due to depletion, and B3 is a period until the surface of the organic resin coating film is deteriorated by the photocatalytic effect). That is, when compared with the equivalent film thickness, according to the present invention, compared to the above (1) and (2), the contamination resistance and self-cleaning effect due to the photocatalytic effect are maintained over the longest period. Thus, an excellent effect can be brought about in a pre-coated metal sheet subjected to restrictions on the coating thickness.
- the photocatalyst layer on the outermost surface gradually wears out due to the effect of the photocatalyst, but it does not necessarily wear out uniformly, and when viewed finely, there is a region where there is a large amount of remaining film (less film loss) and a remaining film. There are few regions (a lot of film is worn out), and wears out while forming unevenness in the thickness direction.
- the protective layer does not have a self-cleaning effect, so that the self-cleaning property is remarkably lowered when a certain percentage of the protective layer is exposed.
- a self-cleaning function can be provided by adding a photocatalyst to the protective layer, excellent self-cleaning properties can be maintained even after the protective layer is exposed.
- the photocatalyst is not added to the protective layer, the self-cleaning property is lowered even when the outermost photocatalyst layer remains, whereas the photocatalyst is added to the protective layer.

Abstract
Description
これまで、光触媒皮膜の形成方法としてはポストコート法が主流であった。そのため、金属材料を最終製品の形状に加工した後、また建材、屋外構造物であれば、現地での施工時に光触媒皮膜を形成するのが一般的であった。この方法では、最終製品の形状としたのちに皮膜を塗装し、あるいは塗装は現地での施工となることから、皮膜を構成する樹脂や塗装する膜厚などに制限がなく、要求性能に応じた皮膜を形成することが可能であった。
ところが、あらかじめ塗装して、需要家で使用する状態で出荷するプレコート金属では、加工性の制約やコストの観点から、一定以上の厚さの皮膜を形成することは難しく、この制限の中で、長期間にわたって耐汚染性、セルフクリーニング性を維持することができるプレコート金属板が望まれていた。
(1)下地金属板、及びその表面に有機樹脂被覆層を有するプレコート金属板上に、少なくとも2層の光触媒活性を有する皮膜を形成した表面処理プレコート金属板であって、該少なくとも2層の皮膜が、炭素数1以上12以下のアルキル基、アリール基、カルボキシル基、水酸基、及びそれらの組み合わせからなる群から選択される有機基を有するアルコキシシラン、エポキシ基を有するアルコキシシラン、アミノ基を有するアルコキシシラン、テトラアルコキシシラン、並びにそれらの組み合わせからなる群から選択されるアルコキシシランの縮合物からなる無機−有機複合体樹脂を含み、かつ光触媒活性を有する物質を、その含有量が最外層皮膜で最も多く、内層皮膜となるほど少なくなるように含有していることを特徴とする表面処理プレコート金属板。
(2)前記無機−有機複合体樹脂に含まれる有機基がメチル基、またはフェニル基である(1)に記載の表面処理プレコート金属板。
(3)前記皮膜の各層中の光触媒活性を有する物質の含有量が、各層の全質量の0.05%~50%である(1)または(2)のいずれかに記載の表面処理プレコート金属板。
(4)有機樹脂被覆層に接する最も内層側皮膜中の光触媒物質の含有量が、最内層皮膜全体に対する質量割合で0.05%~30%である(1)~(3)のいずれかに記載の表面処理プレコート金属板。
(5)前記光触媒活性を有する物質がアナターゼ型の構造を含む酸化チタンである(1)~(4)のいずれかに記載の表面処理プレコート金属板。
(6)前記下地金属板が、鋼板、ステンレス鋼板、チタン板、チタン合金板、アルミニウム板、アルミニウム合金板又はこれら金属板にめっき処理しためっき金属板から選ばれる(1)~(5)のいずれかに記載の表面処理プレコート金属板。
(7)炭素数1以上12以下のアルキル基、アリール基、カルボキシル基、水酸基、及びそれらの組み合わせからなる群から選択される有機基を有するアルコキシシラン、エポキシ基を有するアルコキシシラン、アミノ基を有するアルコキシシラン、テトラアルコキシシラン、及びそれらの組み合わせからなる群から選択されるアルコキシシラン(a1)、当該アルコキシシラン(a1)の加水分解物(a2)並びに/又は当該アルコキシシラン(a1)の縮合物(a3)を含む無機−有機複合樹脂原料と、光触媒活性を有する物質と、を含有することを特徴とする表面処理液。
(8)(7)に記載の表面処理液を、有機樹脂被覆層を有するプレコート金属板に塗布、硬化することを特徴とする表面処理プレコート金属板の製造方法。
(9)光触媒活性を有する物質の含有量が異なる複数の(7)に記載の表面処理液を、有機樹脂被覆層を有するプレコート金属板に同時に塗布した後に、同時に乾燥焼付けし、前記有機樹脂被覆層の上に、光触媒活性を有する物質の含有量が最外層皮膜で最も多く、内層皮膜となるほど少ない多層皮膜を形成することを特徴とする、表面処理プレコート金属板の製造方法。
これまで、光触媒効果による耐汚染性機能を示すプレコート金属板の代表的な塗膜構成としては、上述のように、(1)プレコート金属板の有機樹脂系塗膜層の上に直接光触媒層を設けたもの、及び(2)プレコート金属板の有機樹脂系塗膜層と光触媒層との間に保護層を設けたもの、が知られている。これらの場合において、光触媒層が自身の光触媒作用のために劣化し、その結果光触媒層が減耗によって消失するまでの期間Aと、光触媒層と接したプレコート金属板の有機樹脂塗膜の表面が光触媒効果によって劣化するまでの期間B、について検討する。(1)では基材(ここでは、下地金属板とその表面に形成した有機樹脂塗膜層で構成されたプレコート金属板のことをいう)の有機樹脂塗膜層に光触媒層が直接接触しているため、一般には、劣化した光触媒層が減耗によって消失するまでの期間A1と比較して、有機樹脂塗膜の表面が光触媒効果によって劣化するまでの期間B1の方が短く、A1>B1の関係となっている。(2)では有機樹脂系塗膜層が保護層によって保護されていることから、有機樹脂塗膜の表面が光触媒効果によって劣化するまでの期間B2は、劣化した光触媒層が減耗によって消失するまでの期間A2と比較して大幅に長く、A2≪B2の関係となる。このため、光触媒による耐汚染性、セルフクリーニング機能の持続期間は、(1)の場合にはB1に、(2)の場合にはA2に支配されることとなる。
