Description

【0001】
【発明の属する技術分野】
本発明はPDP(プラズマディスプレイパネル)や液晶などの表示装置用カバー及び壁取付用ブラケット、スタンド等の表示装置用カバー据付用部品に関するものである。
【0002】
【従来の技術】
PDPや液晶などの表示装置用カバーや表示装置用カバー据付用部品は、プレス成形又は板金加工した鉄板又はアルミ板を最終工程にて塗装し製造するか、又は樹脂のモールド成形品やマグネシウムダイカスト品、マグネシウムモールド品を最終工程にて塗装して製造するものであった。
【0003】
【発明が解決しようとする課題】
しかし、カバー形状に成形した後に塗装するためには高価な専用治具が必要であり、複雑な部品形状であるため下地処理や塗装に手間がかかり製造コストが非常に高かった。
また液晶やPDPなどの表示装置用カバー及び表示装置用カバー据付用部品は、外観が非常に重視される。したがって、塗装板の後工程でのプレス成形では傷が付き易く、特にカバーは複雑な部品形状のためプレス工程数が多く、傷がつき易く困難であった。
【0004】
鉄板製のカバーは、放熱性が悪くファンの能力を上げるなどの対策が必要であり、また鉄板製は重いため携帯用や大型のディスプレイには好ましくなかった。樹脂モールド品はEMC対策のメッキ処理等が必要なため製造コストが高く、特に大型のディスプレイには使用できず、放熱性も劣っていた。マグネシウムダイカストやマグネシウムモールド品は製造上薄肉化できずアルミ製に比べて重くなる。またプレス品に比べて金型寿命も短く金型費が高価であること、PDPなどの大型ディスプレイとしては寸法精度に問題があり製造が困難で、製造しても歩留まりが低いことから製造コストが高かった。
本発明はこのような点に鑑み、生産性、製造コスト、外観、放熱性と成形性に優れた表示装置用カバー及び表示装置用カバー据付用部品を提供するものである。
【0005】
【課題を解決するための手段】
本発明者らは上記課題に鑑み鋭意検討した結果、片面に特定の有機樹脂皮膜層を被覆して形成したアルミニウム材を用いたPDP又は液晶の表示装置用カバーにより上記課題を解決し得ることを見出し、この知見に基づき本発明をなすに至った。
すなわち本発明は、
(1)アルミニウム板のプレス成形により作製する表示装置用カバー又は表示装置用カバー据付用部品であって、プレス成形時の、成形性の向上、耐傷付き性、外観の低下の防止が要求される面である片面に、最外層有機樹脂微粒子を含有する有機樹脂皮膜であり、該最外層の有機樹脂皮膜が平均粒径5〜100μmの有機樹脂微粒子を含み塗膜の表面粗さRaが0.2μm以上、5μm以下である塗膜を設けた樹脂被覆アルミニウム板をプレス加工して作製されていることを特徴とする表示装置用カバー又は表示装置用カバー据付用部品
)有機樹脂微粒子の配合量が最外層有機樹脂皮膜の塗料中の全固形分に対して1〜25質量%であることを特徴とする()項記載の表示装置用カバー又は表示装置用カバー据付用部品
)有機樹脂皮膜のトータル膜厚が10μm以上、25μm以下であることを特徴とする(又は)項に記載の表示装置用カバー又は表示装置用カバー据付用部品
)有機樹脂微粒子がポリアミド樹脂又はアクリル樹脂の微粒子であることを特徴とする()〜()項のいずれかに記載の表示装置用カバー又は表示装置用カバー据付用部品
)部品がカシメにより接合されたことを特徴とする(1)〜()項のいずれかに記載の表示装置用カバー又は表示装置用カバー据付用部品及び
(6)アルミニウム板のプレス成形により作製する表示装置用カバー又は表示装置用カバー据付用部品の製造方法であって、プレス成形時の、成形性の向上、耐傷付き性、外観の低下の防止が要求される面である片面に、最外層が有機樹脂微粒子を含有する有機樹脂皮膜であり、該最外層の有機樹脂皮膜が平均粒径5〜100μmの有機樹脂微粒子を含み塗膜の表面粗さRaが0.2μm以上、5μm以下である塗膜を設け、該樹脂被覆アルミニウム板をプレス加工して作製されることを特徴とする表示装置用カバー又は表示装置用カバー据付用部品の製造方法
を提供するものである。
【0006】
【発明の実施の形態】
本発明の表示装置用カバー及び表示装置用カバー据付用部品は、塗装が容易で安価な塗装アルミニウム板を使ってプレス加工や板金加工して製造するため、部品形状で塗装する必要がなく、非常に安価に製造することが可能である。アルミニウム板製であるため軽量で、樹脂のように高価なEMC対策が必要なく放熱性にも優れる。またプレス加工であるため、寸法精度もよく安価である。
本発明のPDP、液晶ディスプレイ等の表示装置用カバー及び表示装置用カバー据付用部品は、アルミニウム板の片面に特定の有機樹脂皮膜層を有する樹脂被覆アルミニウム板を用いたことを特徴とする。
【0007】
使用されるアルミニウム板は、要求強度や成形性により選定し特に制限されるものではないが、成形性が良く強度も高いJIS A 5052やA 5182材が好ましい。
本発明に用いられるアルミニウム板は片面に有機樹脂皮膜層を有する。片面のみに有機樹脂皮膜を形成することによって、EMC対策に必要な通電が可能となる。
本発明における有機樹脂皮膜は、ポリエステル系、アクリル系、エポキシ系等が使用され特に制限されるものではないが、好ましくは加工性の良いポリエステルである。
【0008】
また、本発明における最外層の有機樹脂皮膜には5〜100μmの有機樹脂微粒子を含有させることができ、この微粒子添加によって塗膜の表面粗さRaを0.2μm以上、5μm以下に制御しプレス成形時の成形性を向上させることができる。塗膜の表面粗さRaが0.2μm未満では、表面粗面化によるプレス成形時の成形油のプーリング効果による成形性向上及び接触面積低減による耐傷付き性向上効果が小さい。塗膜の表面粗さRaが5μmを超える場合は微粒子の脱落又は微粒子を起点とした塗膜の割れが発生しやすくなり外観が低下する。
【0009】
また、塗膜の表面粗さRaは有機樹脂皮膜に配合する有機樹脂微粒子の粒径、配合量によって制御できる。有機樹脂微粒子の粒径は5〜100μmであり、より好ましくは20〜90μmの範囲である。有機樹脂微粒子の粒径が5μmより小さいと配合量を多くしても表面粗さRaが0.2μm以上にならず、粒径が100μmを超える場合は、有機樹脂微粒子と塗膜の密着性が悪くなり成形性が著しく低下する。
有機樹脂微粒子の配合量は最外層有機樹脂皮膜の塗料中に全固形分に対し1〜25質量%となるよう配合するのが好ましい。より好ましくは3〜20質量%の範囲である。有機樹脂微粒子の配合量が1質量%より少ない場合は、特に粒径の小さいもので塗膜表面粗さRaが0.2μm以上にならない。また、配合量が25質量%を超える場合は、有機樹脂皮膜の伸びが低下し、成形性が低下する。
【0010】
有機樹脂皮膜のトータル膜厚は、10μm以上25μm以下である。膜厚が10μm未満の場合、色むらができやすく、特にプレス加工した場合に目立ち外観が低下する。膜厚が25μmを超える場合、曲げ加工等での伸びについていけず塗膜が割れやすくなり成形性が低下する。
有機樹脂微粒子としては、ポリアミド樹脂、アクリル樹脂、ウレタン樹脂、フェノール樹脂などからなる樹脂微粒子が挙げられ、特に樹脂自身が潤滑性のあるポリアミド樹脂、汎用的であるアクリル樹脂が好ましい。
【0011】
塗装アルミ板はスポット溶接等の溶接ができないが、リベットを用いなくても、TOXカシメやバーリングカシメ等のカシメを行うことで、外観を損なわず部品接合が可能である。
また、成形時及び成形後のアルミニウム板に対する有機樹脂皮膜の密着性及び耐食性を向上させるため,通常アルミニウム板状に下地皮膜を形成する。下地皮膜はアルミニウム板の両面に施すのが好ましいが、これに限定されるものではない。この下地皮膜の形成は脱脂処理の前処理を行ったアルミニウム板上に通常の方法で形成され、その種類は特に制限はなく、反応型クロメート、塗布型クロメート及び環境対応のノンクロメート等の中から選ばれる。
さらに、有機樹脂皮膜は、上記有機樹脂微粒子の他、成形性向上のためにPTFE、ワックス等の潤滑成分を併用してもかまわない。
【0012】
【実施例】
以下、図面に従って本発明を詳細に説明する。
次のように、図1に拡大断面図で示す、片面のみに第1層と第2層の2層からなる塗膜を有する樹脂被覆アルミニウム材を製造した。すなわち、リン酸クロメート下地処理2を施したアルミニウム板1の片面のみに、第1層目に有機樹脂微粒子を含有しない有機樹脂皮膜3、最外層である第2層目に下記表1に示すように有機樹脂微粒子5を含有する有機樹脂皮膜4を形成した。
まず、リン酸クロメート処理したA5182−O板上に微粒子を含有しないポリエステルプライマー塗料をバーコーターを用いて塗布し、240℃で50秒間焼き付けることにより第1層の有機樹脂皮膜を膜厚5μm形成した。次いで、表1に示す条件にて微粒子を含有するポリエステル塗料を、第1層の有機樹脂皮膜の上にバーコーターを用いて塗布し、上記プライマー塗料の場合と同じ条件で焼き付けることにより第2層の有機樹脂皮膜を形成した。
【0013】
得られた樹脂被覆アルミニウム材をプレスで絞り加工、曲げ加工を行うことにより、表示装置用カバー及びその据付用部品に加工した。加工例を図2及び図3に示す。図2は本発明によるカバー(リア)の一実施例の斜視図である。6は上記工程で得た厚さ1mmのアルミニウム板加工品としてのリアカバーであり、7は有機樹脂微粒子配合のポリエステル樹脂皮膜であり、リアカバーの大きさは、幅1m、高さ0.6mである。図3は、PDP表示装置の好ましい例の分解斜視図である。6は本発明に係るリアカバー、8はシャーシ、9はPDP、10はフロントカバー、11は壁掛けブラケットである。
【0014】
得られた樹脂被覆アルミニウム材を図2のリアカバーに加工した結果を表1に示した。
表1の結果より明らかなように、本発明の樹脂被覆アルミニウム材を用いた表示装置のカバーは、加工時の傷、塗膜割れ、色むらがなく外観に非常に優れる。
比較例12は、塗膜の表面粗さが小さ過ぎるため加工時の傷が発生した。比較例13、14及び15は、塗膜の表面粗さが大き過ぎるため塗膜の割れが発生した。比較例16は、トータル塗膜の厚さが薄すぎるため塗膜の色むらが発生した。比較例17は、トータル膜厚が厚すぎるため塗膜の割れが発生した。
これらに対して、本発明例1〜11は成形性に非常に優れ、外観に優れる。

【発明の効果】
以上に説明したように、本発明による表示装置用カバー及び表示装置用カバー据付用部品によれば、従来できなかった塗装アルミニウム板をプレス加工や板金加工して表示装置用カバー及び表示装置用カバー据付用部品を製造できるため、部品形状で塗装する必要がなく、安価に表示装置用カバー及び表示装置用カバー据付用部品を製造できるものである。
また塗膜の表面粗さRaを、有機樹脂微粒子を配合することによって0.2μm以上、5μm以下に制御し、塗膜の厚さを10μm以上、25μm以下にすることで、塗装アルミニウム板の成形性を大きく向上させ外観の優れたカバー及び据付部品を得ることができる。

The present invention relates to a cover for a display device such as a plasma display panel (PDP) or a liquid crystal display, a bracket for mounting on a wall, and a cover for a display device such as a stand.
[0002]
[Prior art]

[0003]
[Problems to be solved by the invention]
However, an expensive dedicated jig is necessary for painting after molding into a cover shape, and since the shape of the component is complicated, the substrate processing and painting are troublesome and the manufacturing cost is very high.
In addition, the appearance of a display device cover and a display device cover mounting component such as a liquid crystal display or a PDP is very important. Therefore, the press molding in the subsequent process of the coated plate is likely to be scratched, and in particular, the cover has a complicated part shape, so the number of press processes is large, and the scratch is easily scratched and difficult.
[0004]
The iron plate cover has poor heat dissipation and requires measures such as increasing the fan's ability, and the iron plate is heavy and is not preferable for portable or large displays. The resin mold product requires a plating treatment for EMC measures and the like, so the manufacturing cost is high. In particular, the resin mold product cannot be used for a large display, and heat dissipation is inferior. Magnesium die-casting and magnesium mold products cannot be thinned due to manufacturing and are heavier than aluminum products.

[0006]
DETAILED DESCRIPTION OF THE INVENTION
The display device cover and the display device cover installation part of the present invention are manufactured by press processing or sheet metal processing using a painted aluminum plate that is easy to paint and inexpensive. It can be manufactured at low cost. Since it is made of an aluminum plate, it is lightweight and does not require an expensive EMC measure like resin, and has excellent heat dissipation. Moreover, since it is press work, its dimensional accuracy is good and it is inexpensive.
The display device cover and the display device cover mounting part such as a PDP and a liquid crystal display according to the present invention are characterized by using a resin-coated aluminum plate having a specific organic resin film layer on one side of the aluminum plate.
[0007]
The aluminum plate to be used is selected and not particularly limited depending on the required strength and formability, but JIS A 5052 and A 5182 materials having good formability and high strength are preferred.
The aluminum plate used in the present invention has an organic resin film layer on one side. By forming the organic resin film only on one side, it is possible to energize necessary for EMC countermeasures.
The organic resin film in the present invention is not particularly limited and polyester, acrylic, epoxy, or the like is used, but is preferably a polyester with good processability.
[0008]
Moreover, the organic resin film of the outermost layer in the present invention can contain 5 to 100 μm of organic resin fine particles, and by adding the fine particles, the surface roughness Ra of the coating film is controlled to 0.2 μm or more and 5 μm or less. Formability at the time of molding can be improved. When the surface roughness Ra of the coating film is less than 0.2 μm, the effect of improving the formability by the pooling effect of the molding oil during press molding by surface roughening and the effect of improving the scratch resistance by reducing the contact area are small. When the surface roughness Ra of the coating film exceeds 5 μm, the fine particles are easily dropped or the coating film is easily cracked starting from the fine particles, and the appearance is deteriorated.
[0009]
Further, the surface roughness Ra of the coating film can be controlled by the particle diameter and blending amount of the organic resin fine particles blended in the organic resin film. The particle diameter of the organic resin fine particles is 5 to 100 μm, and more preferably 20 to 90 μm. If the particle size of the organic resin particles is smaller than 5 μm, the surface roughness Ra does not exceed 0.2 μm even if the blending amount is increased. If the particle size exceeds 100 μm, the adhesion between the organic resin particles and the coating film is It becomes worse and the moldability is remarkably lowered.
It is preferable to mix the organic resin fine particles in an amount of 1 to 25% by mass with respect to the total solid content in the paint of the outermost organic resin film. More preferably, it is the range of 3-20 mass%. When the blending amount of the organic resin fine particles is less than 1% by mass, the coating film surface roughness Ra is not more than 0.2 μm, particularly with a small particle size. Moreover, when a compounding quantity exceeds 25 mass%, the elongation of an organic resin film will fall and a moldability will fall.
[0010]
The total film thickness of the organic resin film is 10 μm or more and 25 μm or less. When the film thickness is less than 10 μm, color unevenness is likely to occur, and the appearance is particularly noticeable when pressed. When the film thickness exceeds 25 μm, the film cannot be easily stretched by bending or the like, and the coating film is easily broken and the moldability is lowered.
Examples of the organic resin fine particles include resin fine particles made of a polyamide resin, an acrylic resin, a urethane resin, a phenol resin, and the like. In particular, a polyamide resin having lubricity and a general-purpose acrylic resin are preferable.
[0011]
The coated aluminum plate cannot be welded by spot welding or the like, but even if rivets are not used, it is possible to join parts without damaging the appearance by caulking such as TOX caulking or burring caulking.
Also, in order to improve the adhesion and corrosion resistance of the organic resin film to the aluminum plate during and after molding, a base film is usually formed in the form of an aluminum plate. The undercoat is preferably applied to both sides of the aluminum plate, but is not limited thereto. The base film is formed on an aluminum plate that has been pre-treated with a degreasing process by a normal method, and the type thereof is not particularly limited, and includes reactive chromate, coating chromate, and environmentally friendly non-chromate. To be elected.
Furthermore, in addition to the organic resin fine particles, the organic resin film may be used in combination with a lubricating component such as PTFE or wax in order to improve moldability.
[0012]
【Example】
Hereinafter, the present invention will be described in detail with reference to the drawings.
A resin-coated aluminum material having a coating film composed of two layers of a first layer and a second layer on only one side, as shown in an enlarged sectional view in FIG. 1, was produced as follows. That is, as shown in Table 1 below, the organic resin film 3 does not contain organic resin fine particles in the first layer, and the second layer, which is the outermost layer, only on one side of the aluminum plate 1 that has been subjected to the phosphoric acid chromate base treatment 2. The organic resin film 4 containing the organic resin fine particles 5 was formed.
First, a polyester primer paint not containing fine particles was applied onto a phosphoric acid chromate-treated A5182-O plate using a bar coater, and baked at 240 ° C. for 50 seconds to form a first organic resin film having a thickness of 5 μm. . Next, a polyester paint containing fine particles under the conditions shown in Table 1 was applied onto the organic resin film of the first layer using a bar coater and baked under the same conditions as in the case of the primer paint. An organic resin film was formed.
[0013]
The obtained resin-coated aluminum material was processed into a display device cover and its installation parts by drawing and bending with a press. Examples of processing are shown in FIGS. FIG. 2 is a perspective view of an embodiment of a cover (rear) according to the present invention. 6 is a rear cover as a 1 mm-thick aluminum plate processed product obtained in the above process, 7 is a polyester resin film containing organic resin fine particles, and the size of the rear cover is 1 m wide and 0.6 m high. . FIG. 3 is an exploded perspective view of a preferred example of a PDP display device. 6 is a rear cover according to the present invention, 8 is a chassis, 9 is a PDP, 10 is a front cover, and 11 is a wall-mounted bracket.
[0014]
Table 1 shows the results of processing the obtained resin-coated aluminum material into the rear cover of FIG.
As is apparent from the results in Table 1, the cover of the display device using the resin-coated aluminum material of the present invention is very excellent in appearance without any scratches, coating cracks, and color unevenness during processing.
In Comparative Example 12, scratches occurred during processing because the surface roughness of the coating film was too small. In Comparative Examples 13, 14, and 15, cracks in the coating film occurred because the surface roughness of the coating film was too large. In Comparative Example 16, the coating film was uneven in color because the total coating film thickness was too thin. In Comparative Example 17, since the total film thickness was too thick, the coating film was cracked.
On the other hand, Examples 1 to 11 of the present invention are very excellent in moldability and excellent in appearance.

【The invention's effect】
As described above, according to the display device cover and the display device cover installation part according to the present invention, the display device cover and the display device cover can be obtained by press-working or sheet-metal processing of a coated aluminum plate, which has not been conventionally possible. Since the installation parts can be manufactured, it is not necessary to paint in the shape of the parts, and the display device cover and the display device cover installation parts can be manufactured at low cost.
Moreover, the surface roughness Ra of the coating film is controlled to 0.2 μm or more and 5 μm or less by blending organic resin fine particles, and the coating film thickness is set to 10 μm or more and 25 μm or less to form a coated aluminum plate. Thus, it is possible to obtain a cover and a mounting part having a great appearance and excellent appearance.
Since it is made of aluminum, it is lightweight and does not require EMC measures, and has the effect of excellent heat dissipation.
