Description

【0001】
【発明の属する技術分野】
本発明は、メッキ調の外観を有する塗膜形成に適した塗料組成物に関する。
【0002】
【従来の技術】
従来から塗膜に光輝性のメタリック感を与える塗装方法として、脂肪酸とともにボールミルにて粉砕処理された、厚さ0.1〜1μm、平均粒径5〜60μmのアルミニウムフレーク顔料を含む組成物が使用されている。
【0003】
これらのメタリック塗料に光輝剤として配合されるアルミニウムフレークは、その性質によりリーフィング型とノンリーフィング型に分類されている。リーフィング型アルミニウムのフレークは通常ステアリン酸とともに粉砕処理されており、その表面張力が低いため、塗装したときにメタリック塗膜の上層面に浮上し、基材と平行に配列した状態で塗膜を形成して、連続したアルミニウム面を形成しやすい。しかしながら、上層面に浮上したアルミニウムフレーク顔料は塗膜硬化後においても塗膜に固定化されておらず、指触により剥離して容易に取り除かれる。また、未硬化の状態でウエットオンウエット方式にてクリヤー塗料を塗装すると、アルミニウムフレークの配向が乱れて外観が低下する。一方、メタリック塗膜を加熱硬化後にクリヤー塗料を塗装すると、クリヤー塗膜との密着性が確保できないという問題点を有している。
【0004】
よって、工業用塗料に適応されているのは主に後者のノンリーフィング型アルミニウムフレークである。
ノンリーフィング型アルミニウムフレークのみを含む従来のメタリック塗料は、アルミニウムフレークが通常オレイン酸とともに粉砕処理されており、光輝材として配合したアルミニウムフレームが、塗装時メタリック塗膜の内部に分散するため、クリヤー塗膜との密着性は良好であるが、光輝材として配合したアルミニウムフレークの厚さが厚く、エナメル塗膜内部に分散するため、アルミニウムフレークの重なりが肉眼にて観察され、連続なメッキ調外観を有する塗膜を形成できないという問題点を有している。
【0005】
このようなメタリック塗料の外観性を改良した塗料組成物として特開昭53−9836号には、揮発性キャリヤー、金属微粒子および結合材から成り、金属微粒子は1000オングストローム以下の厚さを有する概して不規則に造型された金属小板であり、かつ、結合材対金属小板の比率が0.05対1〜10対1となる様な量で存在することを特徴とする塗料組成物が提案されている。しかしながら、このメタリック塗料組成物では、被塗物の研ぎ跡隠蔽性に劣り、連続なメッキ調外観を有する塗膜を安定的に形成できない。
【0006】
【発明が解決しようとする課題】
本発明は、従来のこのような問題点に着目してなされたもので、塗膜物性に問題がなく、被塗物の研ぎ跡隠蔽性に優れ、かつ連続なメッキ調外観に優れる塗膜を安定的に形成できる塗料組成物を提供することを目的とする。
【0007】
【課題を解決するための手段】
本発明は、溶剤、光輝材および塗膜形成樹脂を含有する塗料組成物であって、厚さが0.08μm以下で、かつ平均粒径が5〜40μmである微小金属箔(A)および厚さが0.1〜1μm、かつ平均粒径が1〜60μmであり、脂肪酸とともにボールミルにて粉砕処理されたノンリーフィング型アルミニウムフレーク(B)を光輝材として含有し、光輝材対塗膜形成樹脂の重量比率が1対〜1対20であり、微小金属箔(A)対ノンリーフィング型アルミニウムフレーク(B)の重量比率が1対0.1〜1対であることを特徴とする塗料組成物である。
【0008】
【発明の実施の形態】
本発明の塗料組成物が塗装される被塗物としては、鉄、アルミニウム、銅もしくはこれらの合金を含む金属類、ガラス、コンクリート等の無機材料、ポリエチレン、ポリプロピレン、エチレン−酢酸ビニル共重合体、ポリアミド、ポリアクリル、ポリエステル、塩化ビニル樹脂、塩化ビニリデン樹脂、ポリカーボネート、ポリウレタン、アクリロニトリル−ブタジエン−スチレン共重合体等の樹脂成形品および各種FRPなどのプラスチック材料、木材、紙などが挙げられる。 これら被塗物は直接本発明の塗料組成物を塗装してもよくまた基材に予め適宜なアンダーコートやプレコート処理を施してもよい。
【0009】
本発明の塗料組成物は光輝材として微小金属箔(A)、およびノンリーフィング型アルミニウムフレーク(B)を含有して構成される。微小金属箔(A)は、厚さ0.08μm以下、好ましくは0.02〜0.06μmで、かつ平均粒径が5〜40μm、好ましくは5〜20μmである。微小金属箔(A)は、蒸着(真空蒸着を含む)法、無電解メッキ法およびスパッター法等により製造されたものが挙げられる。市販品としては、例えばMetalure(AVERY DENNISON社製、商標、微小金属箔の厚さ0.01〜0.08μm、平均粒径6〜16μm)、Metasheen(WOLSTENHOLME INTERNATIONAL LTD製、商標、微小金属箔の厚さ0.01〜0.08μm、平均粒径8〜20μm)等が挙げられる。微小金属箔(A)の素材としては、用途に応じてAl、Mg、Cu、Au、Ag等が例示され、特に制限されない。
【0010】
ノンリーフィング型アルミニウムフレーク(B)は、従来から塗料の光輝材として使用されている、オレイン酸等の脂肪酸とともにボールミルにて粉砕処理された厚さ0.1〜1μm、好ましくは0.1〜0.5μmであり、かつ平均粒径5〜60μm、好ましくは5〜30μmのものが使用できる。厚さが1μmを越えるもの、あるいは平均粒径が60μmを越えるものはアルミニウムフレークの重なりが肉眼にて観察され、連続なメッキ調外観が低下する。
【0011】
微小金属箔(A)とノンリーフィング型アルミニウムフレーク(B)を合わせた光輝材の配合量は、光輝材対塗膜形成樹脂の重量比率が、1対1〜1対20である。光輝材の配合量が1対を越えると密着性試験において凝集剥離を生じる。また、光輝材の配合量が1対20より低い場合、光輝材の配向性が低下し、メッキ調外観が低下する。
【0012】
微小金属箔(A)とノンリーフィング型アルミニウムフレーク(B)との重量比率は、1対0.1〜1対2である。ノンリーフィング型アルミニウムフレーク(B)の配合量が1対0.1未満の場合、被塗物の研ぎ跡隠蔽性に劣り、連続なメッキ調外観を有する塗膜を安定的に形成できない。この原因は、微小金属箔(A)の厚さが0.08μm以下と低く、被塗物の研ぎ跡に沿って変形して配向するためと推測される。一方、ノンリーフィング型アルミニウムフレーク(B)の配合量が1対を越えた場合、ノンリーフィング型アルミニウムフレーク同士の重なりが肉眼にて観察され、連続なメッキ調外観を有する塗膜を形成できない。
【0013】
本発明の塗料組成物は、微小金属箔(A)とノンリーフィング型アルミニウムフレーク(B)を併用し、その重量比率を適当な範囲内とすることにより、被塗物の研ぎ跡隠蔽性が良好であり、かつ連続なメッキ調外観性を有する塗膜を形成できるようにしたものである。
すなわち、本発明の塗料組成物においては、被塗物の研ぎ跡に沿って変形し難いノンリーフィング型アルミニウムフレーク(B)と微小金属箔(A)を併用することにより、微小金属箔(A)の変形が抑えられ、被塗物の研ぎ跡隠蔽性が良好である。また、その外観はノンリーフィング型アルミニウムフレーク(B)同士の重なりを微小金属箔(A)が隠蔽し、連続なメッキ調外観を有する塗膜を形成できる。
【0014】
本発明の塗料組成物における塗膜形成樹脂としては、通常塗料用として使用されている樹脂を制限無く使用できる。例えばアクリル樹脂、ポリオレフィン樹脂、塩素化ポリオレフィン樹脂、ポリエステル樹脂、アルキド樹脂、繊維素系樹脂等を1種単独で、あるいは2種以上を組み合わせて非架橋のラッカータイプとすることも、また例えば、イソシアネート化合物、メラミン樹脂等の架橋剤と組み合わせて、1液または2液型の架橋硬化型塗料として使用することもできる。
【0015】
本発明の塗料組成物には、必要に応じてその他の顔料、各種添加剤などを配合することができる。顔料としては従来から塗料用に常用されているものが用いられ、例えば有機系としてアゾレーキ系顔料、フタロシアニン顔料、インジゴ系顔料、ペリノン系顔料、ペリレン系顔料、キノフタロン系顔料、ジオキサジン系顔料、キナクリドン系顔料等を挙げることができ、無機系としては黄鉛、黄色酸化鉄、ベンガラ、カーボンブラック、二酸化チタン等を挙げられる。また添加剤としてはベンゾトリアゾール、蓚酸アニリド系等の紫外線吸収剤、ベンゾフェノール系等の酸化防止剤、シリコーン系等のレベリング剤、ワックス、有機ベントナイト等の粘性制御剤、硬化触媒等が挙げられる。
【0016】
本発明の塗料組成物は、水または有機溶剤に分散ないし溶解して使用する。有機溶剤としては、芳香族炭化水素系溶剤、エステル系溶剤、ケトン系溶剤、アルコール系溶剤、エーテル系溶剤等が使用できる。
【0017】
本発明の塗料組成物は、霧化式塗装機を用い、エアスプレー方式、静電方式等従来から公知の塗装方法により塗装することができる。
【0018】
本発明の塗料組成物は、その塗装に先立ってプライマーを塗装することができ、また本発明の塗料組成物の塗膜上にクリヤーコート塗料を塗装することができる。これらの場合、プライマーおよびクリヤーコート塗料としては従来から用いられている塗料が使用できる。
【0019】
本発明の塗料組成物をプライマーおよびクリヤー塗料とともに塗装する場合は、プライマーが未硬化の状態にて、ウェット・オン・ウェット方式にて塗装することもできる。また、本発明のメタリック塗料組成物を塗装した後、加熱後あるいはウェット・オン・ウェット方式にてクリヤーコートを塗装することもできる。

BACKGROUND OF THE INVENTION
The present invention relates to a coating composition suitable for forming a coating film having a plating-like appearance.
[0002]
[Prior art]
Conventionally, a composition containing aluminum flake pigment having a thickness of 0.1 to 1 μm and an average particle size of 5 to 60 μm, which has been pulverized with a fatty acid and ball mill, has been used as a coating method to give a glossy metallic feeling to the coating film. Has been.
[0003]
Aluminum flakes blended in these metallic paints as a brightening agent are classified into leafing type and non-leafing type depending on their properties. Leafing aluminum flakes are usually pulverized with stearic acid, and because of their low surface tension, they float on the upper surface of the metallic coating when coated and form a coating in a state aligned in parallel with the substrate. Thus, it is easy to form a continuous aluminum surface. However, the aluminum flake pigment that has floated on the upper layer surface is not fixed to the coating film even after the coating film is cured, and is easily removed by peeling off with a finger. Moreover, when a clear coating is applied by a wet-on-wet method in an uncured state, the orientation of the aluminum flakes is disturbed and the appearance is lowered. On the other hand, when a clear coating is applied after heat-curing the metallic coating, there is a problem that adhesion to the clear coating cannot be ensured.
[0004]
Therefore, the latter non-leafing aluminum flakes are mainly applied to industrial coatings.
In conventional metallic paints containing only non-leafing aluminum flakes, the aluminum flakes are usually pulverized with oleic acid, and the aluminum frame blended as a glittering material is dispersed inside the metallic paint film during painting. Although the adhesion to the film is good, the thickness of the aluminum flakes blended as a bright material is thick and dispersed inside the enamel coating film, so the overlap of aluminum flakes is observed with the naked eye, and a continuous plating appearance There is a problem that a coating film cannot be formed.
[0005]
Japanese Patent Application Laid-Open No. 53-9836 discloses a coating composition with improved appearance of such a metallic paint, comprising a volatile carrier, fine metal particles, and a binder, and the fine metal particles generally have a thickness of 1000 angstroms or less. A coating composition is proposed, characterized in that it is a regularly formed metal platelet and is present in an amount such that the ratio of binder to metal platelet is 0.05: 1 to 10: 1. ing. However, this metallic paint composition is inferior in the sharpness hiding property of the object to be coated, and cannot stably form a coating film having a continuous plating appearance.
[0006]
[Problems to be solved by the invention]
The present invention has been made by paying attention to such conventional problems, and there is no problem in the physical properties of the coating film, and it is excellent in the sharpness hiding property of the object to be coated and excellent in continuous plating appearance. An object of the present invention is to provide a coating composition that can be stably formed.
[0007]
[Means for Solving the Problems]
The present invention is a coating composition containing a solvent, a bright material and a coating film-forming resin, having a thickness of 0.08 μm or less and an average particle diameter of 5 to 40 μm, and a thickness of the fine metal foil (A) Saga 0.1~1Myu m, Ri or one average particle size of 1~60μm der, containing non-leafing type aluminum flakes milled in a ball mill together with a fatty acid (B) as a luminous material, the luminous material Tainuri The weight ratio of the film forming resin is 1: 1 to 1:20 , and the weight ratio of the fine metal foil (A) to the non-leafing type aluminum flake (B) is 1: 0.1 to 1: 2. The coating composition.
[0008]
DETAILED DESCRIPTION OF THE INVENTION
Examples of the object to be coated with the coating composition of the present invention include metals including iron, aluminum, copper or alloys thereof, glass, concrete and other inorganic materials, polyethylene, polypropylene, ethylene-vinyl acetate copolymer, Examples include polyamide, polyacrylic, polyester, vinyl chloride resin, vinylidene chloride resin, polycarbonate, polyurethane, resin molded products such as acrylonitrile-butadiene-styrene copolymer, plastic materials such as various FRPs, wood, and paper. These coatings may be applied directly with the coating composition of the present invention, or an appropriate undercoat or precoat treatment may be applied to the substrate in advance.
[0009]
The coating composition of the present invention comprises a fine metal foil (A) and a non-leafing aluminum flake (B) as a bright material. The fine metal foil (A) has a thickness of 0.08 μm or less, preferably 0.02 to 0.06 μm, and an average particle size of 5 to 40 μm, preferably 5 to 20 μm. Examples of the fine metal foil (A) include those produced by a vapor deposition (including vacuum vapor deposition) method, an electroless plating method, a sputtering method, and the like. Commercially available products include, for example, Metalure (AVERY DENNISON, trademark, fine metal foil thickness 0.01 to 0.08 μm, average particle size 6 to 16 μm), Metasheen (made by WOLSTNHOLME INTERNATIONAL LTD, trademark, fine metal foil And a thickness of 0.01 to 0.08 μm and an average particle size of 8 to 20 μm). Examples of the material of the fine metal foil (A) include Al, Mg, Cu, Au, Ag, and the like according to the application, and are not particularly limited.
[0010]
The non-leafing type aluminum flake (B) has a thickness of 0.1 to 1 μm, preferably 0.1 to 0, which has been pulverized by a ball mill together with a fatty acid such as oleic acid, which has been conventionally used as a brightening material for paints. The average particle diameter is 5 to 60 μm, preferably 5 to 30 μm. When the thickness exceeds 1 μm or the average particle diameter exceeds 60 μm, the overlap of aluminum flakes is observed with the naked eye, and the continuous plating appearance is deteriorated.
[0011]
The blending amount of the glitter material combining the fine metal foil (A) and the non-leafing aluminum flake (B) is such that the weight ratio of the glitter material to the coating film forming resin is 1 : 1 to 1:20. When the blending amount of the glittering material exceeds 1: 1 , aggregation peeling occurs in the adhesion test. Moreover, when the compounding quantity of a brilliant material is lower than 1:20 , the orientation of a brilliant material falls and a plating tone external appearance falls.
[0012]
The weight ratio of the fine metal foil (A) to the non-leafing aluminum flakes (B) is 1 to 0.1 to 1 to 2. When the blending amount of the non-leafing type aluminum flake (B) is less than 1 to 0.1 , it is inferior to the sharpness hiding property of the object to be coated, and a coating film having a continuous plating appearance cannot be stably formed. This is presumably because the thickness of the fine metal foil (A) is as low as 0.08 μm or less, and deforms and aligns along the sharpened trace of the object to be coated. On the other hand, when the blending amount of the non-leafing type aluminum flakes (B) exceeds 1: 2 , the overlapping of the non-leafing type aluminum flakes is observed with the naked eye, and a coating film having a continuous plating appearance cannot be formed.
[0013]
The coating composition of the present invention has good sharpness concealment of the object to be coated by using the fine metal foil (A) and the non-leafing type aluminum flake (B) in combination and setting the weight ratio within an appropriate range. In addition, a coating film having a continuous plating tone appearance can be formed.
That is, in the coating composition of the present invention, the non-leafing type aluminum flake (B) and the fine metal foil (A) which are not easily deformed along the sharpened trace of the object to be coated are used in combination. Deformation is suppressed, and the sharpness hiding property of the object to be coated is good. Moreover, the external appearance can hide the overlap of non-leafing type aluminum flakes (B) by the fine metal foil (A), and a coating film having a continuous plating appearance can be formed.
[0014]
As the film-forming resin in the coating composition of the present invention, a resin usually used for coating can be used without limitation. For example, an acrylic resin, a polyolefin resin, a chlorinated polyolefin resin, a polyester resin, an alkyd resin, a fiber-based resin, etc. can be used alone or in combination of two or more to form a non-crosslinked lacquer type. In combination with a crosslinking agent such as a compound or a melamine resin, it can also be used as a one-component or two-component cross-linking curable coating.
[0015]
In the coating composition of the present invention, other pigments, various additives and the like can be blended as necessary. As pigments, those conventionally used for paints are used. For example, organic pigments such as azo lake pigments, phthalocyanine pigments, indigo pigments, perinone pigments, perylene pigments, quinophthalone pigments, dioxazine pigments, and quinacridone pigments. A pigment etc. can be mentioned, As an inorganic type, yellow lead, yellow iron oxide, Bengala, carbon black, titanium dioxide, etc. are mentioned. Examples of the additives include ultraviolet absorbers such as benzotriazole and succinic acid anilide, antioxidants such as benzophenol, leveling agents such as silicone, viscosity control agents such as wax and organic bentonite, and curing catalysts.
[0016]
The coating composition of the present invention is used after being dispersed or dissolved in water or an organic solvent. As the organic solvent, aromatic hydrocarbon solvents, ester solvents, ketone solvents, alcohol solvents, ether solvents and the like can be used.
[0017]
The coating composition of the present invention can be applied by a conventionally known coating method such as an air spray method or an electrostatic method using an atomizing coater.
[0018]
Prior to the coating of the coating composition of the present invention, a primer can be applied, and a clear coat coating can be applied on the coating film of the coating composition of the present invention. In these cases, conventionally used paints can be used as the primer and the clear coat paint.
[0019]
When the coating composition of the present invention is applied together with a primer and a clear coating, it can also be applied by a wet-on-wet method with the primer uncured. Further, after applying the metallic coating composition of the present invention, the clear coat can be applied after heating or by a wet-on-wet method.
