【発明の属する技術分野】
本発明は、無機顔料と樹脂組成物とを含む塗料組成物に関する。特に本発明は、無機顔料の沈降防止が施された塗料組成物に関する。
【0002】
【従来の技術】
自動車のボディ等に塗装される有機系塗料(メタリック塗料)として、パールマイカを無機顔料とするパール塗料やアルミニウムフレークを無機顔料とするアルミニウム塗料が用いられている。パール塗料やアルミニウム塗料をむらなく塗装するためには、塗料中の無機顔料が均一に分散していることが必要である。しかし、パールマイカやアルミニウムフレークは、比重が大きいため(パールマイカ:比重約3.1、アルミニウムフレーク:比重約2.7)、塗料中で容易に沈殿が生じる。従来、無機顔料の沈降を防止するために、アマイドワックス系、酸化ポリエチレン系の沈降防止剤やアエロジルを使用することがよく知られている。
【0003】
たとえば、特開平10−59828号公報において、皮膜形成剤及び有機溶剤を含有する(塗料)美爪料において、ポリオキシエチレン鎖及び/又はポリオキシプロピレン鎖を有するシリル化剤で処理した増粘付与性粉体を配合することにより、塗料を増粘させて顔料の沈降を防止させることを開示する。

【0005】
【発明が解決しようとする課題】
従来の無機顔料と樹脂組成物とを含む有機系塗料では、塗料全体の粘度を増加させることにより、無機顔料の沈降を抑えている。このため、塗料全体の粘度が高いので、コーティング時に均一に塗布することが困難であった。
【0006】
そこで本発明は、上記の課題を解決することのできる塗料組成物を提供することを目的とする。本発明は、より具体的には、塗料全体の粘度を増加させることなく、無機顔料の沈降防止が可能な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】
即ち、本発明の望ましい態様は、無機顔料と樹脂組成物とを含む塗料組成物であって、平均粒子径が0.1〜2.0μmで、表面が疎水化処理された無機粉体を前記樹脂組成物に対して、0.1〜50wt%含むことを特徴とする。また、本発明の他の望ましい態様においては、前記無機粉体の形状が真球状であることを特徴とする。
【0008】
無機顔料と樹脂組成物とを含む塗料組成物は、たとえば、2コート1ベーク用に使用されている公知の塗料を用いることができる。無機顔料としては、アルミフレークなどの金属粉、マイカ粉が挙げられる。樹脂組成物の基体樹脂としては、硬化性樹脂が好適であり、具体的には、水酸基及び必要に応じてカルボキシル基を含有するアクリル系又はポリエステル系樹脂を基体樹脂、アミノ樹脂を硬化剤として含有するものが挙げられる。基体樹脂の希釈溶媒としてブチルアセテートやキシレンなどの溶媒が用いられる。塗料組成物に対して、必要に応じて、上記以外に着色顔料、体質顔料、重合体微粒子、塗面調整剤、セルロースアセテート(及びこれらの誘導体)、硬化触媒、その他の塗料用添加剤などを配合してもよい。
【0009】
無機粉体はたとえばシリカ粉が好適である。形状が真球状である無機粉体として、具体的には、アドマテックス製のアドマファインが挙げられる。無機粉体は、アルミフレークなどの無機顔料の凝集による巨大化を防止し、無機顔料の沈降を防止する。無機顔料の沈降防止に関しては、無機顔料が沈降する際の障害となるように無機粉体を均一に分散配置させることが効果的である。
【0010】
また、無機顔料の凝集を防止するためには、接触面積ができるだけ小さい無機粉体が無機顔料の間に挟まるようにすることが効果的であり、真球状の無機粉体を用いることにより、無機顔料と無機粉体との接触が点接触となり、無機顔料の凝集防止により効果的である。なお、真球状の無機粉体は、無機粉体士の接触点が少ないため、塗料に添加した場合でも分散しやすく、かつ、多量に添加しない限り塗料が増粘することもない。
【0011】
樹脂組成物は疎水性が強いためシリカなどの無機粉体をそのまま混ぜて分散させることは困難である。そのため、シリカなどの無機粉体の表面にトリメチルシリル化などの疎水化処理を施すことにより、有機系塗料での分散が可能になる。疎水化処理は、トリメチルシリル化に限られず、多様な処理が可能である。たとえば、シリカを例に取ると、シリカ表面の構造としては下記のものが挙げられる。
【化1】
【0012】
ここで、Rは芳香族炭化水素、炭化水素、アクリル基、メタクリル基、またはエポキシ基を含む有機基である。
【0013】
無機粉体の平均粒子径は、0.1〜2.0μmが好ましいが、0.1〜0.5μmがより好ましい。無機粉体の平均粒子径が0.1μm未満だと、無機粉体が凝集しやすくなり、無機粉体の分散が困難であり、たとえ、分散できても塗料の粘度が上がり易くなる。また、無機粉体の平均粒子径が2.0μmより大きくなると、粉自身が沈降しやすくなり、無機顔料の沈降防止効果が大幅に低下する。
【0014】
樹脂組成物(希釈溶媒等の不揮発性分を除く)に対する無機粉体の含有量は、0.1〜50wt%が好ましいが、0.3〜10wt%がより好ましい。
【0015】
なお、本発明の塗料組成物は、溶剤型塗料、非水ディスパージョン型塗料のいずれにも用いられる。
【0016】
本発明の塗料組成物によれば、塗料を増粘させることなく、無機顔料の沈降防止効果が得られる。無機顔料が沈降しないので、塗料を長期保存することができる。また、塗装時においては、塗料の均一性およびコーティング性の向上により、塗膜の仕上がり性が向上し、塗膜の強度、つや、光沢度等の物性に悪影響を及ぼさない。さらに、樹脂組成物の硬化時にも無機顔料の沈降防止作用があるため、アンダーフィルのような接着分野にも応用展開が可能である。
【0017】

【0025】
さらに、上記100mlメスシリンダ中の試料の上部と下部を各々50mlずつ分取し、それをよくかき混ぜたのち、電着、中塗塗料を塗装した銅板に塗装した。実際に塗装したときの塗装作業性、塗面のなめらかさ、色及びつやの差異を調べた(表2参照)。光沢度は、鮮明度光沢度計(PGd計)を用いて、塗装表面などの表面光沢を鮮明度光沢(Gd値)として測定した。ここでは、60℃鏡面光沢度の値を用いた。また、明度、色相および色差は、村上色彩製分光光度計を用いて測定した。

【0029】
〔評価結果〕
実施例1は顔料の沈降が生じず、かつ、光沢性が良いことから希釈安定性が良好であることが確認された。また、実施例1は熱安定性も良好であることが確認された。すなわち、無機顔料と樹脂組成物とを含む塗料組成物において、塗料全体の粘度を増加させることなく、無機顔料の沈降を効果的に防止することができ、塗料を均一に塗布することができる。
【0030】

BACKGROUND OF THE INVENTION
The present invention relates to a coating composition containing an inorganic pigment and a resin composition. In particular, the present invention relates to a coating composition in which settling of inorganic pigments is prevented.
[0002]
[Prior art]
As organic paints (metallic paints) applied to the body of automobiles, pearl paints using pearl mica as an inorganic pigment and aluminum paints using aluminum flake as an inorganic pigment are used. In order to apply pearl paint and aluminum paint evenly, it is necessary that the inorganic pigment in the paint is uniformly dispersed. However, since pearl mica and aluminum flakes have a large specific gravity (pearl mica: specific gravity about 3.1, aluminum flakes: specific gravity about 2.7), precipitation easily occurs in the paint. Conventionally, in order to prevent sedimentation of inorganic pigments, it is well known to use an amide wax-based or polyethylene oxide-based sedimentation inhibitor or Aerosil.
[0003]
For example, in JP-A-10-59828, in a (paint) beauty nail containing a film-forming agent and an organic solvent, a thickening treatment treated with a silylating agent having a polyoxyethylene chain and / or a polyoxypropylene chain is provided. It is disclosed that by adding a functional powder, the paint is thickened to prevent precipitation of the pigment.
[0004]
[Patent Document 1]
Japanese Patent Laid-Open No. 10-59828
[Problems to be solved by the invention]
In an organic paint containing a conventional inorganic pigment and a resin composition, sedimentation of the inorganic pigment is suppressed by increasing the viscosity of the entire paint. For this reason, since the viscosity of the whole coating material is high, it was difficult to apply uniformly at the time of coating.
[0006]
Then, an object of this invention is to provide the coating composition which can solve said subject. More specifically, an object of the present invention is to provide a coating composition capable of preventing sedimentation of inorganic pigments without increasing the viscosity of the entire coating.
[0007]
[Means for Solving the Problems]
That is, a desirable aspect of the present invention is a coating composition containing an inorganic pigment and a resin composition, wherein the inorganic powder whose average particle size is 0.1 to 2.0 μm and whose surface is hydrophobized is described above. It is characterized by containing 0.1 to 50 wt% with respect to the resin composition. In another desirable aspect of the present invention, the inorganic powder has a spherical shape.
[0008]
As the coating composition containing the inorganic pigment and the resin composition, for example, a known coating used for 2-coat 1-bake can be used. Examples of the inorganic pigment include metal powder such as aluminum flake and mica powder. As the base resin of the resin composition, a curable resin is preferable. Specifically, an acrylic or polyester resin containing a hydroxyl group and, if necessary, a carboxyl group is contained as a base resin, and an amino resin is contained as a curing agent. To do. A solvent such as butyl acetate or xylene is used as a diluting solvent for the base resin. If necessary, in addition to the above, coloring pigments, extender pigments, polymer fine particles, coating surface conditioners, cellulose acetate (and their derivatives), curing catalysts, other paint additives, etc. You may mix | blend.
[0009]
For example, silica powder is suitable as the inorganic powder. Specific examples of the inorganic powder having a true spherical shape include Admafine manufactured by Admatechs. The inorganic powder prevents enlarging due to aggregation of inorganic pigments such as aluminum flakes and prevents sedimentation of the inorganic pigment. For preventing sedimentation of the inorganic pigment, it is effective to disperse and disperse the inorganic powder uniformly so as to be an obstacle when the inorganic pigment settles.
[0010]
In order to prevent aggregation of the inorganic pigment, it is effective to sandwich an inorganic powder having a contact area as small as possible between the inorganic pigments. The contact between the pigment and the inorganic powder becomes a point contact, which is effective for preventing aggregation of the inorganic pigment. In addition, since the spherical inorganic powder has few contact points with the inorganic powder, it is easy to disperse even when added to the paint, and the paint does not thicken unless added in a large amount.
[0011]
Since the resin composition has strong hydrophobicity, it is difficult to mix and disperse inorganic powder such as silica as it is. For this reason, the surface of an inorganic powder such as silica is subjected to a hydrophobic treatment such as trimethylsilylation, whereby dispersion with an organic paint becomes possible. The hydrophobizing treatment is not limited to trimethylsilylation, and various treatments are possible. For example, taking silica as an example, the structure of the silica surface includes the following.
[Chemical 1]
[0012]
Here, R is an organic group including an aromatic hydrocarbon, a hydrocarbon, an acrylic group, a methacryl group, or an epoxy group.
[0013]
The average particle size of the inorganic powder is preferably 0.1 to 2.0 μm, more preferably 0.1 to 0.5 μm. If the average particle size of the inorganic powder is less than 0.1 μm, the inorganic powder tends to aggregate, and it is difficult to disperse the inorganic powder. Even if it can be dispersed, the viscosity of the coating tends to increase. On the other hand, when the average particle size of the inorganic powder is larger than 2.0 μm, the powder itself tends to settle, and the precipitation preventing effect of the inorganic pigment is greatly reduced.
[0014]
The content of the inorganic powder with respect to the resin composition (excluding non-volatile components such as a dilution solvent) is preferably 0.1 to 50 wt%, more preferably 0.3 to 10 wt%.
[0015]
The coating composition of the present invention is used for both solvent-type paints and non-aqueous dispersion-type paints.
[0016]
According to the coating composition of the present invention, the effect of preventing sedimentation of the inorganic pigment can be obtained without increasing the viscosity of the coating. Since the inorganic pigment does not settle, the paint can be stored for a long time. Further, at the time of painting, the finish of the coating film is improved by improving the uniformity and coating properties of the paint, and the physical properties such as the strength, gloss and glossiness of the coating film are not adversely affected. Furthermore, since the inorganic pigment has an anti-settling action even when the resin composition is cured, it can be applied to the adhesive field such as underfill.
[0017]
DETAILED DESCRIPTION OF THE INVENTION
Hereinafter, the present invention will be described through embodiments of the invention.
[0018]
[Production of base paint]
Paint composed of acrylic resin (15 parts by weight) / polyester resin (45 parts by weight) / melanin resin (substrate resin) (40 parts by weight) .... 100 parts by weight Additive: acid catalyst (1.5 phr) / sag stop Agent / microgel (12 phr) / Benton (0.35 phr) / UV absorber (3.0 phr)
Pigment composition: aluminum (3.1 pwc) / mica (6.7 pwc) / iron oxide yellow (11.5 pwc) / carbon black (0.01 pwc)
The above components and solvent were mixed to obtain a base paint.
[0019]
[Conventional example]
The base paint was used as a conventional paint.
[0020]
[Example 1]
Hydrophobic treatment (specifically, trimethylsilylation) using hexamethyldisilazane for Admafine (Admatech's SO-C1, average particle size of about 0.2 μm, Admafine is almost spherical) ). The coating material of Example 1 was obtained by adding 5.0 wt% of hydrophobized Admafine to the base resin of the base coating material.
[0021]
[Comparative Example 1]
A paint of Comparative Example 1 was obtained by the same process as Example 1 except that the average particle size of Admafine was 2.5 μm.
[0022]
[Comparative Example 2]
A paint of Comparative Example 2 was obtained by the same process as Example 1 except that Admafine was not subjected to surface treatment.
[0023]
[Comparative Example 3]
A paint of Comparative Example 3 was obtained by the same process as in Example 1 except that the amount of admafine added was 55.0 wt%.
[0024]
〔Evaluation methods〕
[Dilution stability]
100 ml of a sample diluted to a specified viscosity (20 ± 1 second) was placed in a 100 ml graduated cylinder, the mouth was sealed, and left at room temperature for 48 hours. The sample was observed from the lateral direction of the graduated cylinder, and the sedimentation and liberation of the pigment, separation of the varnish, and the like were examined (see Table 1).
[0025]
Further, 50 ml each of the upper and lower portions of the sample in the 100 ml graduated cylinder were taken out and mixed well, and then applied to a copper plate coated with electrodeposition and intermediate coating. Differences in paint workability, smoothness of paint surface, color, and gloss when actually painted were examined (see Table 2). The glossiness was measured by using the sharpness gloss meter (PGd meter) as the surface glossiness of the painted surface or the like as the sharpness gloss (Gd value). Here, the value of 60 ° C. specular gloss was used. The brightness, hue and color difference were measured using a spectrophotometer manufactured by Murakami Color.
[0026]
In Table 2, L represents lightness (white to black), a represents hue (red to green), b represents hue (yellow to blue), and ΔE represents color difference. The lightness difference between the painted surface at the top of the sample and the painted surface at the bottom of the sample is ΔL, and the difference between the a and b values is Δa and Δb, respectively.
[0027]
[Thermal stability]
The sample was diluted with thinner (n-acylpropanol / i-butanol = 1/1) to a viscosity of 30 ± 1 seconds at 20 ± 1 ° C. The diluted sample (187.5 cc) was placed in a 250 cc container (manufactured by Tinplate) and sealed. This sample was subjected to viscosity measurement immediately after adjustment (initial stage) and after being held at 60 ° C. for a predetermined time (16, 24, 32 hours) (see Table 2). Viscosity measurement after holding at 60 ° C. for each time was performed after cooling the prepared paint to 20 ± 1 ° C., confirming the appearance, and further thoroughly stirring.
[0028]
Viscosity was measured using a Ford cup (No. 4, caliber: 4.12 mm) according to the viscometer and measurement method specified in ASTM D1200.
[Table 1]
[Table 2]
[0029]
〔Evaluation results〕
In Example 1, precipitation of the pigment did not occur and gloss was good, so that it was confirmed that the dilution stability was good. Moreover, it was confirmed that Example 1 also has good thermal stability. That is, in a coating composition containing an inorganic pigment and a resin composition, sedimentation of the inorganic pigment can be effectively prevented and the coating can be uniformly applied without increasing the viscosity of the entire coating.
[0030]
On the other hand, the conventional paint causes pigment settling and is inferior in glossiness, so that the dilution stability is lower than that in Example 1, and the thermal stability is also inferior to that in Example 1.
[0031]
In Comparative Example 1, since the average particle diameter of silica is too large, the effect of preventing precipitation of the pigment is poor, and the dilution stability is lower than that in Example 1.
[0032]
In Comparative Example 2, since the silica surface was not hydrophobized, the silica was agglomerated due to aggregation and was not formed as a paint.
[0033]
In Comparative Example 3, since the amount of silica added was too large, the silica became a gel due to aggregation and was not formed as a paint.
[0034]
As mentioned above, although this invention was demonstrated using embodiment, the technical scope of this invention is not limited to the range as described in the said embodiment. Various changes or improvements can be added to the above embodiment. It is apparent from the description of the scope of claims that embodiments with such changes or improvements can be included in the technical scope of the present invention.
[0035]
【The invention's effect】
As is apparent from the above description, according to the present invention, in the coating composition containing the inorganic pigment and the resin composition, the precipitation of the inorganic pigment can be effectively prevented without increasing the viscosity of the entire coating. it can.
