Description
本発明は、触媒内での電荷移動により酸化反応及び/又は還元反応を行う複合酸化物結晶からなる電荷移動型触媒を含有する低温硬化型電荷移動型触媒含有コーティング組成物、及び該組成物の被膜を基材表面に形成した表面処理基材に関する。 The present invention relates to a low-temperature curable charge transfer catalyst-containing coating composition containing a charge transfer catalyst comprising a composite oxide crystal that undergoes an oxidation reaction and / or a reduction reaction by charge transfer in the catalyst, and The present invention relates to a surface-treated substrate having a coating film formed on the substrate surface.
従来、基材表面に光触媒機能を有する層(例えばアナターゼ型酸化チタンを含有する層)を形成し、光触媒を光励起させて層の表面を親水化させ、防汚性を付与するようにしたものが数多く知られている。この光触媒方式では、紫外線と水の存在が必須条件となるが、天候、季節、昼夜、建物の向きなどの環境条件により変化し効果が一定でない。例えば、天気の良い日は紫外線は強いが水分がなく、雨の日は水分はあるが紫外線が弱いというように、相反する条件が必要となる。 Conventionally, a layer having a photocatalytic function (for example, a layer containing anatase-type titanium oxide) is formed on the surface of a substrate, and the photocatalyst is photoexcited to hydrophilize the surface of the layer to impart antifouling properties. Many are known. In this photocatalytic method, the presence of ultraviolet rays and water is an essential condition, but the effect varies depending on environmental conditions such as weather, season, day and night, and the direction of the building, and the effect is not constant. For example, contradictory conditions are required, such as when the weather is fine, the ultraviolet rays are strong but there is no moisture, and on rainy days there is moisture but the ultraviolet rays are weak.
このような技術上の問題点を克服するために、光や水の存在といった環境条件の変化に関わりなく、防汚性を付与可能にし、また抗菌性や防臭性の付与も可能にした電荷移動型触媒が提唱されている(特許文献1:特許第3514702号公報、特許文献2:特開2007−185553号公報、特許文献3:特開2007−38119号公報)。 In order to overcome such technical problems, charge transfer can be imparted with antifouling property and antibacterial and deodorant properties regardless of changes in environmental conditions such as the presence of light and water. Type catalysts have been proposed (Patent Document 1: Japanese Patent No. 3514702, Patent Document 2: Japanese Patent Laid-Open No. 2007-185553, Patent Document 3: Japanese Patent Laid-Open No. 2007-38119).
しかしながら、このような電荷移動型触媒は粉末であって、従来は溶媒にバインダーを加えてコーティング溶液としていたが、よいバインダーがなく、塗布しても電荷移動型触媒粉末が脱落したり、防汚性等の性能が持続しなかったりと不具合が生じていた。また、例えばタイル表面に塗工しようとする場合、1,000℃以上で焼付けをしなければならないという問題もあった。更に光は必要ないが、熱が必要なため、熱源の近くでしか応用できないものもあり、熱源がない所への応用が難しいという問題もあった。
本発明に用いるバインダーに関する先行技術としては、上記特許文献1〜3に加えて下記特許文献4〜7が挙げられる。
However, such a charge transfer catalyst is a powder, and conventionally a binder is added to a solvent to form a coating solution. However, there is no good binder, and even when applied, the charge transfer catalyst powder falls off or is antifouling. There was a problem that performance such as sex did not last. In addition, for example, when applying to a tile surface, there is a problem that baking must be performed at 1,000 ° C. or higher. Furthermore, although light is not required, there is a problem that application is only possible near the heat source because heat is required, and it is difficult to apply to a place where there is no heat source.
Prior art relating to the binder used in the present invention includes the following patent documents 4 to 7 in addition to the above patent documents 1 to 3.
本発明は、上記事情に鑑みなされたもので、基材に塗布し、低温で乾燥させるだけで容易に電荷移動型触媒含有被膜を形成でき、その被膜耐久性の向上が可能で、防汚性・抗菌性・防臭性を付与可能な低温硬化型電荷移動型触媒含有コーティング組成物、及び該組成物を基材表面に塗布形成した表面処理基材を提供することを課題とする。 The present invention has been made in view of the above circumstances, and can easily form a charge transfer catalyst-containing coating simply by applying to a substrate and drying at a low temperature, and the durability of the coating can be improved. It is an object of the present invention to provide a low-temperature curable charge transfer catalyst-containing coating composition capable of imparting antibacterial and deodorizing properties, and a surface-treated substrate on which the composition is applied and formed on the substrate surface.
本発明者らは、上記課題を達成するために鋭意検討を行った結果、下記に示す特定の有機ケイ素化合物が、電荷移動型触媒と組み合わせた時に優れた低温硬化性能、バインダー性能を発揮することを見出し、更に通常防汚性を示す光触媒の場合には表面を親水性にしてしまうが、特定の有機ケイ素化合物を組み合わせることにより、撥水性でありながら防汚性も持たせられるということも新たに知見し、本発明を完成するに至った。 As a result of intensive studies to achieve the above-mentioned problems, the present inventors have demonstrated that the following specific organosilicon compounds exhibit excellent low-temperature curing performance and binder performance when combined with a charge transfer catalyst. In the case of photocatalysts that usually exhibit antifouling properties, the surface becomes hydrophilic, but it is also possible to add antifouling properties while being water repellent by combining specific organosilicon compounds. As a result, the present invention has been completed.
従って、本発明は、下記に示す低温硬化型電荷移動型触媒含有コーティング組成物及び表面処理基材を提供する。

Is a ratio of 5 to 200 parts by mass, more preferably a ratio of 10 to 150 parts by mass. When this amount exceeds 200 parts by mass, the stability of the aqueous solution deteriorates. Further, if this amount is less than 5 parts by mass, the binding ability of the charge transfer catalyst may be lowered.
上記加水分解性シラン(A)、(B)あるいはそれらの部分加水分解物を用いて加水分解し、本発明の有機ケイ素化合物を得る場合、溶媒は主として水を使用するが、必要に応じて、水と溶解する有機溶剤であるアルコール、エステル、ケトン、グリコール類を水に添加する形で用いることができる。有機溶剤としては、メチルアルコール、エチルアルコール、1−プロピルアルコール、2−プロピルアルコール等のアルコール類、酢酸メチル、酢酸エチル、アセト酢酸エチル等のエステル類、アセトン、メチルエチルケトン等のケトン類、グリセリン、ジエチレングリコール等のグリコール類などを挙げることができる。 When the hydrolyzable silane (A), (B) or a partial hydrolyzate thereof is used to obtain the organosilicon compound of the present invention, water is mainly used as a solvent.

Organic solvents include alcohols such as methyl alcohol, ethyl alcohol, 1-propyl alcohol and 2-propyl alcohol, esters such as methyl acetate, ethyl acetate and ethyl acetoacetate, ketones such as acetone and methyl ethyl ketone, glycerin and diethylene glycol And the like.
溶媒の量は、上記加水分解性シラン(A)、(B)あるいはそれらの部分加水分解物(以下、原料混合シランともいう。)100質量部に対して400〜5,000質量部が好ましい。更に好ましくは1,000〜3,000質量部である。溶媒の量が400質量部より少ないと反応が進行しすぎ、系が均一にならない場合がある。また液の保存安定性も悪くなる場合がある。一方、5,000質量部より多いと経済的に不利な場合が生じる。 The amount of the solvent is preferably 400 to 5,000 parts by mass with respect to 100 parts by mass of the hydrolyzable silane (A), (B) or a partially hydrolyzed product thereof (hereinafter also referred to as raw material mixed silane). More preferably, it is 1,000-3,000 mass parts. If the amount of the solvent is less than 400 parts by mass, the reaction may proceed excessively and the system may not be uniform. In addition, the storage stability of the liquid may deteriorate. On the other hand, when the amount is more than 5,000 parts by mass, an economical disadvantage may occur.
また、溶媒中の水の量は、水/原料混合シランのモル比率で5〜50が好ましい。このモル比率が5より少ないと加水分解が完全に進行しにくく、液の安定性が悪化する場合がある。一方、50を超えると経済的に不利な場合が生じる。 The amount of water in the solvent is preferably 5 to 50 in terms of the molar ratio of water / raw material mixed silane. When this molar ratio is less than 5, hydrolysis hardly proceeds completely, and the stability of the liquid may be deteriorated. On the other hand, if it exceeds 50, an economical disadvantage may occur.
反応方法としては、(1)原料混合シランを水中あるいは加水分解に必要である以上の量の水を含む有機溶剤中に滴下する方法、(2)原料混合シランあるいは有機溶剤含有原料混合シラン中に水を滴下する方法、(3)加水分解性シラン(B)及び/又はその部分加水分解物を水中あるいは加水分解に必要である以上の量の水を含む有機溶剤中に滴下し、その後、窒素原子含有有機基を含有する加水分解性シラン(A)及び/又はその部分加水分解物を滴下する方法、(4)窒素原子含有有機基を含有する加水分解性シラン(A)及び/又はその部分加水分解物を水中あるいは加水分解に必要である以上の量の水を含む有機溶剤中に滴下し、その後、加水分解性シラン(B)及び/又はその部分加水分解物を滴下する方法などが挙げられるが、有機ケイ素化合物の安定性の点から、特に(1)の反応方法が好ましい。 As the reaction method, (1) a method in which the raw material mixed silane is dropped into water or an organic solvent containing water in an amount more than necessary for hydrolysis, (2) the raw material mixed silane or the organic solvent-containing raw material mixed silane (3) Hydrolyzable silane (B) and / or a partially hydrolyzed product thereof is dropped into water or an organic solvent containing water in an amount more than necessary for hydrolysis, and then nitrogen is added.

なお、本発明において、上記(II)成分である有機ケイ素化合物は水溶液の形で得られるものであるが、有機ケイ素化合物以外の水等の溶媒は、後述する(III)成分としてカウントするものである。
In addition, although the obtained organosilicon compound is obtained in the form of aqueous solution, water is added or removed as necessary, and water is preferably added in an amount of 10 to 2 with respect to 100 parts by mass of the organosilicon compound. The organosilicon compound can be formed by adjusting to a ratio of 1,000 parts by mass, more preferably 10 to 1,000 parts by mass. In this case, if the amount of water is less than 10 parts by mass, the storage stability of the organosilicon compound itself may deteriorate. Moreover, when more than 2,000 mass parts, the quantity which adds an organosilicon compound will increase and it is not preferable in terms of cost.
In the present invention, the organosilicon compound as the component (II) is obtained in the form of an aqueous solution, but a solvent such as water other than the organosilicon compound is counted as the component (III) described later. is there.
この(II)成分をバインダーとして使用することにより、詳細な理由ははっきりと説明できないが、コーティング組成物を水系で安定的なものにすることが可能であり、かつ(I)成分をコーティングした塗膜中で良好にその活性を失うことなくバインドすることができる。また(I)成分の硬化触媒能により、高温下でなくても、低温で塗膜を硬化可能にすることができる。更に、このバインダーと組み合わせることで防汚性でありながら、撥水性にもっていけるという新たな効果も発現する。 Although the detailed reason cannot be clearly explained by using this component (II) as a binder, the coating composition can be made stable in an aqueous system, and the coating composition coated with the component (I) can be used. It can bind well in the membrane without losing its activity. Further, the curing catalytic ability of the component (I) makes it possible to cure the coating film at a low temperature even at a low temperature. Furthermore, when combined with this binder, a new effect that it can be made water-repellent while exhibiting antifouling properties is also exhibited.
上記(I)、(II)成分を分散させる媒体成分である(III)成分は、水及び/又は水含有溶剤が好ましい。環境的な配慮から水単独が好ましいが、場合によっては水含有溶剤でも構わない。その時の溶剤は、アルコール、エステル、ケトン、グリコール類を使用することができる。具体的には、メチルアルコール、エチルアルコール、1−プロピルアルコール、2−プロピルアルコール等のアルコール類、酢酸メチル、酢酸エチル、アセト酢酸エチル等のエステル類、アセトン、メチルエチルケトン等のケトン類、グリセリン、ジエチレングリコール等のグリコール類などを挙げることができる。 The component (III), which is a medium component in which the components (I) and (II) are dispersed, is preferably water and / or a water-containing solvent. Although water alone is preferable from environmental considerations, a water-containing solvent may be used in some cases. As the solvent at that time, alcohol, ester, ketone and glycol can be used. Specifically, alcohols such as methyl alcohol, ethyl alcohol, 1-propyl alcohol and 2-propyl alcohol, esters such as methyl acetate, ethyl acetate and ethyl acetoacetate, ketones such as acetone and methyl ethyl ketone, glycerin and diethylene glycol And the like.

この時、(I)成分の配合量が0.01質量部未満であると防汚性・抗菌性・防臭性等を良好に付与できない。またこの量が10質量部を超える量であると経済的に不利となる。
(II)成分の量が0.01質量部未満であると(I)成分をうまくバインドできない。またこの量が30質量部を超える量であると経済的に不利となる。
(III)成分の配合量が多すぎると実質的な有効成分が減るために経済的に好ましくなく、この量が少なすぎると保存安定性が悪化する場合がある。
The compounding amount of the components (I), (II) and (III) is 0.01 to 10 parts by mass, preferably 0.1 to 10 parts by mass of the component (I) in 100 parts by mass of the total amount. 8 parts by mass, the binder of component (II) is 0.01 to 30 parts by mass, preferably 0.1 to 20 parts by mass, and the water and / or water-containing solvent of component (III) is 99.98 to 60 parts. Contains parts by weight.
At this time, when the blending amount of the component (I) is less than 0.01 parts by mass, antifouling properties, antibacterial properties, deodorizing properties and the like cannot be imparted satisfactorily. Moreover, when this amount exceeds 10 parts by mass, it is economically disadvantageous.
If the amount of component (II) is less than 0.01 parts by mass, component (I) cannot be bound well. Moreover, when this amount exceeds 30 parts by mass, it is economically disadvantageous.
If the blending amount of the component (III) is too large, the substantial active ingredient is reduced, which is economically undesirable. If the amount is too small, the storage stability may be deteriorated.
