産業上の利用分野
本発明は粉体塗料をロール塗装してプレコート金属板を
製造する方法に関する。DETAILED DESCRIPTION OF THE INVENTION Field of the Invention The present invention relates to a method for manufacturing precoated metal sheets by roll coating a powder coating.
従来の技術
近年環境問題や省資源の点から溶剤を含まない塗料によ
る塗装が種々の形で実用化されて来ている。この一つが
いわゆる粉体塗装であり、塗装方式としては静電粉体吹
付法が最も代表的に用いられて来た。BACKGROUND OF THE INVENTION In recent years, various forms of painting using paints that do not contain solvents have been put into practical use from the viewpoint of environmental issues and resource conservation. One of these is so-called powder coating, and electrostatic powder spraying has been most commonly used as the coating method.
静電粉体吹付法は粉体塗料に空気を混ぜて流動化させ、
これを圧縮空気でガンの先端から噴出させ、この時ガン
の先端部に設けた電極によって噴出粉体を高電圧に荷電
させることにより、アースされた被覆物に均一な塗着を
効率よく行なわせるというものである。Electrostatic powder spraying mixes air with powder paint to make it fluid.
This powder is ejected from the tip of the gun using compressed air, and at this time, the ejected powder is charged to a high voltage by an electrode installed at the tip of the gun, allowing for efficient and uniform application of the powder to the grounded coating. That is what it is.
この方式の最大の利点は対象物の形を問わずに利用でき
ることであり、又普及が進んでいることによる利用のし
易さも挙げられる。しかし次の様に限界も多い。The biggest advantage of this method is that it can be used regardless of the shape of the object, and it is also easy to use due to its increasing popularity. However, there are many limitations as follows.
先ず圧縮空気の力で粉体を吹付けるため、被塗物に届い
た粉体が未だ速度を有しており、静電吸引力の方向と異
なる速度成分は粉体の塗着効率を減する。First, the powder is sprayed using the force of compressed air, so the powder that reaches the object still has some velocity, and a velocity component that differs from the direction of the electrostatic attraction force reduces the powder coating efficiency. .
又圧縮空気流が被塗物に折角塗着した粉体を再び吹飛ば
すことによる塗着効率の低下もある。この結果静電粉体
吹付法による一次塗着効率は高々８０％に留まり、又膜
厚もつけ難い。In addition, the compressed air flow blows off the powder that has been applied to the object again, resulting in a decrease in the application efficiency. As a result, the primary coating efficiency by electrostatic powder spraying is only 80% at most, and it is difficult to increase the film thickness.
更には大容量の塗装が必要な時に吹付は量を増大させる
のに、静電ガンの数を増して対処しなければならない。Furthermore, when a large amount of coating is required, the amount of spraying increases, and the number of electrostatic guns must be increased.
更に大きい欠点は粉塵の発生が大なることである０発生
粉塵は集塵回収すればよいが、設備の膨大さ、或いは回
収粉の再利用歩留を考慮すれば、高価な粉体塗血に対し
て更に経済的な不利を加えることになる。An even bigger disadvantage is that a large amount of dust is generated.Although the generated dust can be collected and collected, considering the huge amount of equipment or the reuse rate of the collected powder, it is not recommended to use expensive powder blood coating. This will add to the economic disadvantage.
一方、工程省略、コストダウンの要求に応えて、アルミ
板、冷延鋼板、溶融亜鉛めっき鋼板等を工場であらかじ
め塗装し、加工１組立または施工後に塗装をしなくても
良いようにしたプレコート金属板の使用が益々盛んであ
る。On the other hand, in response to demands for process omissions and cost reductions, pre-coated metals such as aluminum plates, cold-rolled steel plates, hot-dip galvanized steel plates, etc. are coated in advance at the factory, eliminating the need for painting after processing, assembly, or construction. Boards are increasingly being used.
しかしながら、上記静電粉体吹付法によりコイルから連
続塗装ラインでプレコート金属板を製造しようとすると
、多数（たとえば数十台）の静電塗装機を、一定間隔毎
に配置せざるを得なくなると共に、現溶剤系塗料を用い
るラインに比し数倍の塗装スペースを要し、設備費の増
大となる。また塗布量を確保するために、生産速度も思
うように上げられない。However, when trying to manufacture precoated metal sheets from coils on a continuous coating line using the electrostatic powder spraying method described above, it is necessary to arrange a large number of electrostatic coating machines (for example, several dozen units) at regular intervals. Compared to lines that use current solvent-based paints, this method requires several times more painting space and increases equipment costs. In addition, in order to ensure the amount of coating, production speed cannot be increased as desired.
そこで、上記の様な不利の克服を意図して被塗物への粉
体塗料の供給を重力方向によって行う粉体塗装装置も開
発されている（特公昭８１−１４８７１号）。In order to overcome the above-mentioned disadvantages, a powder coating apparatus has been developed in which the powder coating is supplied to the object to be coated in the direction of gravity (Japanese Patent Publication No. 81-14871).
発明が解決しようとする課題
本発明の目的は塗着効率もよく、短いラインで高速で粉
体塗料を塗装してプレコート金属板を提供しようとする
ことである。Problems to be Solved by the Invention An object of the present invention is to provide a precoated metal plate by applying powder coating at high speed in a short line with good coating efficiency.
課題を解決するための手段
本発明は粉体塗料に分散媒を加えてスラリーとし、該ス
ラリーをピックアップロールに供給し。Means for Solving the Problems In the present invention, a dispersion medium is added to a powder coating material to form a slurry, and the slurry is supplied to a pickup roll.
アプリケータロールを介して金属板にスラリーを塗装し
、次いで加熱処理することを特徴とするプレコート金属
板の製造方法である。This is a method for producing a pre-coated metal plate, which is characterized in that a slurry is applied to a metal plate via an applicator roll, and then heat treatment is performed.
作用（発明の詳細な説明） 本発明は粉体塗料をロール塗装することを特徴とする。Effect (detailed description of the invention) The present invention is characterized in that the powder coating is applied by roll coating.
たとえば第３図に示すようにピックアップロールｌ上に
ホー、パー２から粉体塗料３を流下し、これをアプリケ
ーター４を介して金属板５上に塗装する方法が考えられ
る。For example, as shown in FIG. 3, a method may be considered in which a powder coating material 3 is poured down from a hoe and a par 2 onto a pickup roll 1, and is applied onto a metal plate 5 through an applicator 4.
しかしながら、このような方法では粉体塗料が均一にロ
ール上に塗着せず結果として均一な塗装金属板は得られ
ない。However, in such a method, the powder coating is not uniformly applied onto the roll, and as a result, a uniformly coated metal plate cannot be obtained.
そこで粉体塗料に分散媒を加えてスラリーとし、たとえ
ば第４図に示すごとく塗料容器７に収容したスラリー８
をピックアップロールｌでピックアップし、これをアプ
リケーター４を介して金属板５上に転着する方法が考え
られる。Therefore, a dispersion medium is added to the powder paint to form a slurry, and the slurry 8 is stored in a paint container 7 as shown in FIG.
A conceivable method is to pick up the liquid with a pick-up roll l and transfer it onto the metal plate 5 via the applicator 4.
しかしながら粉体塗料の場合粒度分布があり、スラリー
中のある粒子は容器中に沈降する傾向がある。又ピック
アップロールとアプリケータの間隙で細粒子はど間隙を
通り易い、従って、塗装工程前半と工程後半では塗装さ
れる塗料の質が変る恐れもある。However, powder coatings have a particle size distribution and some particles in the slurry tend to settle in the container. Furthermore, fine particles easily pass through the gap between the pick-up roll and the applicator, so there is a risk that the quality of the paint applied will change between the first half of the coating process and the second half of the process.
そこで本発明においては第１図及び第２図にその一例を
示すごとく、スラリーの沈降がなく、又塗料の質を変え
ることなくピックアップロールに供給する方法として、
先ず第１図では、スラリー８を下方に傾斜する塗料供給
傾斜板９上を流下させ、上方よりピックアップロールｌ
を塗料供給傾斜板９に近ずけ、流下するスラリー８と接
触させピックアップし、厚みコントローラーｌＯで膜厚
調整（併せて、塗料表面の平滑化）を行って、次いでア
プリケーターロール４を介して金属板５にスラリーを塗
装する。Therefore, in the present invention, as shown in FIG. 1 and FIG. 2 as an example, as a method of supplying the slurry to the pickup roll without sedimentation and without changing the quality of the paint,
First, in FIG. 1, the slurry 8 is made to flow down on a paint supply inclined plate 9 which is inclined downward, and a pick-up roll l is applied from above.
is brought close to the paint supply inclined plate 9, brought into contact with the flowing slurry 8, and is picked up.The thickness controller 10 adjusts the film thickness (and smooths the paint surface), and then the metal is passed through the applicator roll 4. Paint the slurry on board 5.
次に第２図では、ピックアップロール１に、その幅に均
一にスラリー８を供給できる塗料供給ノズル１Ｂから直
接スラリー８を供給しピー２クアツプさせ、以下上記第
１図の方法と同様にして金属板５にスラリー８を塗装す
る。Next, in FIG. 2, the slurry 8 is directly supplied to the pick-up roll 1 from the paint supply nozzle 1B that can uniformly supply the slurry 8 over its width, and the slurry 8 is peaked up. The slurry 8 is applied to the board 5.
尚、厚みコントローラー１０の代わりに他の手段、例え
ばドクターブレードの如き手段でもよい。Note that other means such as a doctor blade may be used instead of the thickness controller 10.
また、ピックアップされずに、または、金属板５上に塗
布されなかったスラリー８は、ロール下部に設置した塗
料受は皿１２により回収され、塗料供給タンク１５で攪
拌及び分散された後再びピックアップロールｌに供給さ
れる。In addition, the slurry 8 that was not picked up or not coated on the metal plate 5 is collected by a tray 12 in the paint receiver installed at the bottom of the roll, stirred and dispersed in a paint supply tank 15, and then rolled again to be picked up. l is supplied.
この方法で塗料の枕降が防止でき、より均一な塗装が達
成できる。This method prevents paint build-up and achieves a more uniform coating.
ここで分散媒としては、粉体塗料を溶解したり、膨潤も
させたりしないものが好ましく、粉体塗料を溶解したり
１Ｎ潤したりするものでは、塗装加熱処理後に粉体塗料
独特の表面外観及び、塗膜性能が得られない場合がある
０例えば、粉体塗料としてポリエステル系のものを用い
た場合、分散媒としては、水、アルコールの混合系が良
好な結果を示した。Here, it is preferable that the dispersion medium is one that does not dissolve or swell the powder coating.If the dispersion medium dissolves the powder coating or moistens the powder coating by 1N, the dispersion medium may have a surface appearance unique to the powder coating after the heat treatment. For example, when a polyester-based powder coating was used, a mixed system of water and alcohol as a dispersion medium showed good results.
粉体塗料としては、この他、エポキシ系、アクリル系、
ポリエチレン系、ポリアミド系、塩化ビニル系等も市販

Polyethylene-based, polyamide-based, vinyl chloride-based, etc. are also commercially available, and a dispersion medium for each can be selected and used. In addition, the method of slurryizing the powder coating is not particularly limited, and any known method may be used.If necessary, auxiliary agents such as surfactants may be used.Generally, powder coating 2
Preferably, 80 to 40 parts of dispersion medium to 0 to 80 parts,
It is not limited to this.

Therefore, the steel plate may be used after surface treatment such as chemical conversion treatment.
塗装後、粉体塗料の種類に応じた加熱処理を行い、分散
媒の蒸発と共に塗膜の硬化を行う。After coating, heat treatment is performed depending on the type of powder coating to evaporate the dispersion medium and harden the coating.
