電着塗装は、塗膜が均一で密着性に優れ自動化適性を有するなど多くの利点が あるため、自動車ボディの塗装処理等を始め広く応用されている。 電着塗装では、図５にみるように、内面が絶縁層１ａで覆われた電着塗装槽１ の電着塗料中に一方の電極になる被塗装物２と他方の電極となる導電体（例えば 、金属板）からなる電極板３とが浸漬配置されるとともに、被塗装物２・電極板 ３間が電源４により通電され、被塗装物２の表面に電着塗膜が形成される。この ように、被塗装物２が一方の電極となり、電極板３が他方の電極となって電着塗 装がなされる。通常、被塗装物２と電極板３の間はイオン交換膜等の隔膜６で隔 てられている。つまり、電着塗装槽１内は、電極板３を浸漬する極液側と被塗装 物２を浸漬する塗液側とに別れており、塗液側と極液側の間に隔膜６が介在して ているのである。 Electrodeposition coating has many advantages such as uniform coating, excellent adhesion, and suitability for automation. For this reason, it is widely applied, including painting of automobile bodies. In electrodeposition coating, as shown in FIG. 5, an electrodeposition coating tank 1 whose inner surface is covered with an insulating layer 1a In the electrodeposition coating composition, the object to be coated 2 that becomes one electrode and the conductor that becomes the other electrode (for example, , The electrode plate 3 made of a metal plate is soaked and arranged, and the object to be coated 2 and the electrode plate A power source 4 is energized between 3 to form an electrodeposition coating film on the surface of the article 2 to be coated. this So that the object to be coated 2 serves as one electrode and the electrode plate 3 serves as the other electrode. Dressed up. Normally, the object to be coated 2 and the electrode plate 3 are separated by a diaphragm 6 such as an ion exchange membrane. Is being used. That is, in the electrodeposition coating tank 1, the electrode plate 3 is immersed in the electrode liquid side and It is separated from the coating liquid side in which the object 2 is dipped, and the diaphragm 6 is interposed between the coating liquid side and the polar liquid side. -ing
【０００３】 被塗装物２と電極板３の間に隔膜６を設けておくのは、被塗装物２のある塗液 側に皮膜形成イオンの対イオンが蓄積しないように、対イオンを選択的に電極板 ３側に移動させ除くようにするためである。塗液側の液は、皮膜形成イオン、顔 料、溶剤、対イオン（夾雑イオン）を含んでおり、皮膜形成イオンは被塗装物２ 表面の塗膜となって消費されるが、対イオンの方は消費されないため放置してお くと蓄積し問題になる。未消費の対イオンを隔膜６を通して選択的に極液側に移 動させ極液交換で排出するようにし、塗液側に対イオンが蓄積するのを防止する のである。[0003] The diaphragm 6 is provided between the object 2 to be coated and the electrode plate 3 because the coating liquid with the object 2 to be coated is provided. Selectively counter electrodes of the film-forming ions do not accumulate on the side This is to move it to the 3rd side and remove it. The liquid on the coating liquid side is film-forming ions, face It contains materials, solvents, and counterions (contaminant ions). It is consumed as a coating film on the surface, but counter ions are not consumed, so leave it alone. It accumulates and becomes a problem. Selectively transfer unconsumed counterions to the polar liquid side through the diaphragm 6. To prevent the counterions from accumulating on the side of the coating fluid Of.
【０００４】 カチオン型電着塗料においては、対イオン用物質（酸性中和剤）として、例え ば、酢酸が使われる。隔膜６がないと、例えば、酢酸の濃度がどんどん高くなり 、ｐＨが変化し、皮膜の再溶解やピンホールの発生等の不都合が出てくるのであ る。 しかしながら、従来、電極板３の耐久性が十分でないという問題がある。使用 開始時は図６に示す状態であった電極板３は、電気的腐食の急速な進行により、 比較的短期間で図７に示す状態になってしまうのである。図８は、腐食した電極 板３の端部分の拡大外観をあらわし、図９は、腐食した電極板３の端部分の拡大 断面をあらわす。このように、図７のように腐食の進んだ電極板３では、強度が 低下しハンドリングに支障を来したり、あるいは、電極板面積が減少し電着効率 が落ちる等の事態を招来するため、改善が望まれていた。[0004] In the case of cationic electrodeposition paint, for example, it can be used as a counter ion substance (acid neutralizer). For example, acetic acid is used. Without the diaphragm 6, for example, the concentration of acetic acid becomes higher and higher. However, the pH changes, which causes inconveniences such as redissolving the film and generating pinholes. It However, conventionally, there is a problem that the durability of the electrode plate 3 is not sufficient. use The electrode plate 3 which was in the state shown in FIG. 6 at the time of start, due to the rapid progress of electrical corrosion, The state shown in FIG. 7 is reached in a relatively short period of time. Figure 8 shows corroded electrodes The enlarged appearance of the end portion of the plate 3 is shown in FIG. 9, and the enlarged end portion of the corroded electrode plate 3 is shown in FIG. The cross section is shown. In this way, the strength of the electrode plate 3 with advanced corrosion as shown in FIG. Electrodeposition efficiency decreases due to a decrease in the handling, or a decrease in the electrode plate area. Therefore, improvement is desired because it will cause the situation such as falling.

The electrode plate of this invention is also an object to be coated, which is usually one of the electrodes in the electrodeposition coating tank. On the other hand, the other electrode is provided separated by a diaphragm (for preventing counter ion accumulation). In this case, for example, an ion exchange membrane or the like is specifically exemplified as the diaphragm. It goes without saying that it is not limited to the on-exchange membrane.
【０００７】 この考案にかかる電着塗装用電極板（以下、「電極板」と記す）の構成例とし ては、例えば、図１、２に示す電極板１０が挙げられる。電極板１０は、長方形 の金属板（導電板）であって、端部が電気絶縁物（以下、「絶縁物」と記す）１ ２で覆われている。金属板の厚みは、普通、２〜３ｍｍ程度である。そして、電 極板１０の上辺には−側の端子１３が設けられており、先端にある孔１３ａを使 って＋側の端子１３への接続するようにする。なお、端子１３はカチオン電着に おいては＋側である。[0007] As an example of the structure of the electrode plate for electrodeposition coating (hereinafter referred to as "electrode plate") according to the present invention For example, the electrode plate 10 shown in FIGS. The electrode plate 10 is rectangular A metal plate (conductive plate) of which the end portion is an electrical insulator (hereinafter referred to as “insulator”) 1 It is covered with 2. The thickness of the metal plate is usually about 2 to 3 mm. And electric The negative side terminal 13 is provided on the upper side of the electrode plate 10, and the hole 13a at the tip is used. Therefore, the connection is made to the positive terminal 13. The terminal 13 is used for cationic electrodeposition. On the plus side.
【０００８】 電極板１０の端部にいては、図２にみるように、絶縁物１２が端面１０ａと表 裏面１０ａ、１０ｂの縁域に選択的に設けられ、両面のエッジを覆っている形態 が好ましい。最も腐食し易い電極板１０のエッジが絶縁物１２で覆われているこ とになるからである。なお、絶縁物１２は電極板１０の端部全周に設けられてい る必要はなく、例えば、図１にみるように、上辺の真ん中付近に絶縁物未被覆域 １０ｅがあってもよい。というのは、電極板１０の上辺は極液中に浸漬されない 部分であり、電流が流れないからである。[0008] At the end portion of the electrode plate 10, as shown in FIG. 2, the insulator 12 faces the end surface 10a. Form selectively provided in the edge areas of the back surfaces 10a and 10b to cover the edges of both surfaces Is preferred. The edge of the electrode plate 10, which is the most corrosive, is covered with an insulator 12. Because The insulator 12 is provided on the entire circumference of the end portion of the electrode plate 10. For example, as shown in FIG. 1, a non-insulated area is provided near the middle of the upper side. There may be 10e. The upper side of the electrode plate 10 is not immersed in the polar liquid. This is because it is a part and no current flows.
【０００９】 電極板の本体を構成する金属板としては、ステンレス板、チタン板、炭素（カ ーボン）板等が挙げられる。 絶縁物１２用の材料としては、ポリエチレン、ポリプロピレン等の各種合成樹 脂材料、各種合成ゴム材料、天然ゴム材料等が挙げられる。絶縁物１２の形成は 、例えば、樹脂液等の絶縁材溶液を電極板１０の端部に直に塗布硬化（コーティ ング）したり、あるいは、樹脂材料等からなる絶縁テープを接着剤で貼着したり することで実現される。コーティングと貼着の両方を併用して絶縁物１２を形成 してもよい。なお、絶縁物１２は必ずしも電極板１０に固着した状態である必要 はなく、電極板１０から外れさえしなければよいのであって、例えば、電極板１ ０の端部に嵌め込まれることで絶縁物１２が設けられている形態であってもよい 。[0009] Metal plates that compose the body of the electrode plate include stainless steel plates, titanium plates, and carbon (carbon). Carbon) plate and the like. As the material for the insulator 12, various synthetic resins such as polyethylene and polypropylene are used. Examples include fat materials, various synthetic rubber materials, and natural rubber materials. The formation of the insulator 12 For example, an insulating material solution such as a resin liquid is directly applied to the end portion of the electrode plate 10 and cured (coating solution). Or attaching an insulating tape made of resin material with an adhesive. It is realized by doing. Insulator 12 is formed by using both coating and sticking You may. It should be noted that the insulator 12 is not necessarily fixed to the electrode plate 10. It is not necessary to remove the electrode plate 10 from the electrode plate 10. The insulator 12 may be provided by being fitted into the end portion of 0. .
【００１０】 この考案の電極板１０の利用形態は、従来通りである。例えば、図５にみるよ うに、隔膜６で仕切られた極液側に電極板１０を浸漬配置し、塗液側に浸漬され た被塗装物２・電極板１０間を通電することで被塗装物２に電着塗装を施すよう にして用いる。 通常、電極板１０は、図３にみるように、一面に隔膜６を設けたケース５内に 収容するようにする。図４は、図３を分解してあらわす（但しパッキング２０は 省略）。[0010] The utilization form of the electrode plate 10 of this invention is the same as the conventional one. For example, see Figure 5. As described above, the electrode plate 10 is soaked and arranged on the polar liquid side partitioned by the diaphragm 6, and the electrode plate 10 is soaked on the coating liquid side. By applying electricity between the coated object 2 and the electrode plate 10, it is possible to apply the electrodeposition coating to the coated object 2. To use. Usually, the electrode plate 10 is housed in a case 5 having a diaphragm 6 on one surface, as shown in FIG. Try to accommodate. FIG. 4 is an exploded view of FIG. 3 (however, the packing 20 is Omitted).
【００１１】 つまり、ケース５は、図３、４にみるように、ケース本体１５と隔膜６、保護 板１６をパッキング２０を挟んで縁のネジ穴にネジ２１を通しナット２２で締め 付け一体化されたものであり、電極板１０は、ケース本体１５と隔膜６の間に配 される。使用時は、ケース５内は極液で満たされることになる。なお、ケース本 体１５は、通常、ＦＲＰ成形品で出来ており、保護板１６は、パンチングメタル を樹脂コートしたものであり、多数の開孔１６ａが開いていて、この開孔１６ａ を通して隔膜６が塗液側に接することができる。[0011] That is, as shown in FIGS. 3 and 4, the case 5 includes the case body 15, the diaphragm 6, and the protection. Insert the plate 16 into the screw hole at the edge with the packing 20 in between and tighten the nut 22 with the screw 21. The electrode plate 10 is disposed between the case main body 15 and the diaphragm 6. To be done. During use, the inside of the case 5 will be filled with the polar liquid. In addition, case book The body 15 is usually made of an FRP molded product, and the protective plate 16 is a punching metal. Is resin-coated, and a large number of openings 16a are open. The diaphragm 6 can come into contact with the coating liquid side through the through.
【００１２】 この考案の電極板は、カチオン電着塗装において、耐久性の顕著な改善がなさ れるものである。また、この考案の電極板は、隔膜６の無しの電着塗装で使われ てもよい。[0012] The electrode plate of this invention does not have a marked improvement in durability in cationic electrodeposition coating. It is what is done. Moreover, the electrode plate of this invention is used for electrodeposition coating without the diaphragm 6. May be.
【００１３】[0013]
この考案の電極板では、腐食し易い端部が絶縁物で覆われているため、耐久性 が向上している。電極板の端部のエッジは両側（端面と表面又は裏面）から腐食 が進み易いのであるが、腐食し易い端部が絶縁物で覆われていないと易腐食性の 端部が常に存在した状態で急速に腐食し電極板端が後退し電極板面積が減少して いくと同時に、端部から表面に沿って内側へ進む腐食の進行も早くて電極板厚み もどんどん薄くなってゆく。これに対し、この考案の電極板は腐食し易い端部が 絶縁物で覆われ電気的腐食の原因の電流が端部に流れないため、急速な端部腐食 後退および端部から表面に沿って内側へと進む表面腐食進行の両方が抑制され、 電極板面積および厚みの減少が効果的に抑制されるようになる。 The electrode plate of this invention has a durable end because it is easily corroded and covered with an insulator. Has improved. The edge of the electrode plate is corroded from both sides (edge and front or back) Is easy to progress, but if the end that is easily corroded is not covered with an insulator, With the edge always present, it rapidly corrodes, the electrode plate edge recedes, and the electrode plate area decreases. At the same time, the corrosion progresses quickly from the edge to the inside along the surface, and the electrode plate thickness It is getting thinner and thinner. On the other hand, the electrode plate of this invention has an end that is easily corroded. Rapid end corrosion due to the absence of electrical current at the end that is covered by insulation and causes electrical corrosion Both retreat and surface corrosion progress from the edge along the surface to the inside are suppressed, The reduction of the electrode plate area and thickness can be effectively suppressed.

In parallel, the same durability test was performed. When the thickness of the electrode plate of the example after the test was widely examined over the entire surface, The thickness was about 2.4 to 2.5 mm everywhere. Reduction rate, ie [electrode Plate initial thickness a-electrode plate thickness b after test] / [electrode plate initial thickness a] x 100 is It was 17 to 20%.
【００１７】 一方、試験結果後の比較例の電極板の厚みも、面全体にわたって広く調べてみ たところ、何処でもほぼ約１．６〜１．９ｍｍの厚みしかなかった。目減率は、 ３７〜４７％と実施例の約倍であった。 通常、交換の目安の目減率が約５０〜７０％前後であるから、実施例の電極板 は耐久性が大幅に向上していることがよく分かる。[0017] On the other hand, the thickness of the electrode plate of the comparative example after the test results was also widely examined over the entire surface. As a result, everywhere, the thickness was about 1.6 to 1.9 mm. The reduction rate is It was 37 to 47%, which was about twice that of the example. Usually, the reduction rate of the standard of replacement is about 50 to 70%, so the electrode plate of the embodiment It can be seen that the durability is greatly improved.
