Description
本発明は、自動車、家電、建材、容器などの分野で用いられる表面処理鋼板の製造設備、特に、鋼板表面の任意の位置で塗膜厚みを変えられる表面処理鋼板の製造設備およびその製造方法に関する。 TECHNICAL FIELD The present invention relates to a production facility for surface-treated steel sheets used in the fields of automobiles, home appliances, building materials, containers, and the like, and particularly relates to a production facility for surface-treated steel sheets that can change the coating thickness at any position on the surface of the steel sheet and a method for producing the same. .
従来より、自動車、家電、建材、容器などの分野で用いられる鋼板として、耐食性(耐白錆性や耐赤錆性)を向上させる目的で、無機化合物、有機化合物、有機高分子材料、あるいはこれらを複合した材料を含有する塗料を、ロールコーター、浸漬、電解処理などの方法により表面に塗布して塗膜を形成した表面処理鋼板が提案されている。例えば、特許文献1や特許文献2には、有機樹脂とリン酸化合物を含有する塗料を塗布して塗膜を形成した表面処理鋼板やその製造方法が開示されている。また、特許文献3や特許文献4には、有機樹脂とシランカップリング剤、さらにチオカルボニル化合物、リン酸化合物、バナジウム化合物を含有する塗膜を形成した表面処理鋼板が開示されている。さらに、特許文献5には、4価のバナジウム化合物を含む複合酸化層と自己補修性のあるリン酸塩などを含む有機樹脂層からなる2層構造の塗膜を形成した表面処理鋼板が開示されている。 Conventionally, as a steel sheet used in the fields of automobiles, home appliances, building materials, containers, etc., in order to improve corrosion resistance (white rust resistance and red rust resistance), inorganic compounds, organic compounds, organic polymer materials, or these are used. There has been proposed a surface-treated steel sheet in which a paint containing a composite material is applied to the surface by a method such as roll coater, dipping or electrolytic treatment to form a coating film. For example, Patent Document 1 and Patent Document 2 disclose a surface-treated steel sheet in which a coating film is formed by applying a paint containing an organic resin and a phosphoric acid compound, and a method for manufacturing the surface-treated steel sheet. Patent Documents 3 and 4 disclose surface-treated steel sheets in which a coating film containing an organic resin and a silane coupling agent, and further a thiocarbonyl compound, a phosphate compound, and a vanadium compound is formed. Furthermore, Patent Document 5 discloses a surface-treated steel sheet in which a coating film having a two-layer structure comprising a composite oxide layer containing a tetravalent vanadium compound and an organic resin layer containing a self-repairing phosphate is disclosed. ing.
一方、これらの表面処理鋼板には、耐食性に加え、優れたスポット溶接性やシーム溶接性、あるいは電磁波シールド性なども要求されている。
しかしながら、特許文献1〜5に記載の表面処理鋼板では、耐食性の観点から、有機樹脂を含む塗料をロールコーターや浸漬により塗布して、比較的厚い塗膜を鋼板表面に均一に形成しているため、導電性が低下し、スポット溶接やシーム溶接が困難になったり、電磁波シールド性に劣るなどの問題が生じる。一方、塗膜厚みを薄くすれば導電性を向上できるが、耐食性の確保が困難になる。そこで、溶接性や電磁波シールド性などの必要な部位のみの塗膜厚みを変えられる手段が望まれるところであるが、現状のロールコーターや浸漬による塗布では、鋼板の長手方向における比較的長い距離にわたってはロール周速などを制御して塗膜厚みを変えることは可能であるが、鋼板表面の任意の位置で塗膜厚みを変えることは困難である。 However, in the surface-treated steel sheets described in Patent Documents 1 to 5, from the viewpoint of corrosion resistance, a paint containing an organic resin is applied by a roll coater or dipping to form a relatively thick coating film uniformly on the steel sheet surface. For this reason, the conductivity is lowered, and spot welding and seam welding become difficult, and problems such as poor electromagnetic shielding properties arise. On the other hand, if the thickness of the coating film is reduced, the conductivity can be improved, but it is difficult to ensure the corrosion resistance. Therefore, there is a need for a means that can change the thickness of the coating only on the necessary parts such as weldability and electromagnetic shielding properties, but in the current roll coater and immersion coating, over a relatively long distance in the longitudinal direction of the steel sheet. Although it is possible to change the coating thickness by controlling the roll peripheral speed or the like, it is difficult to change the coating thickness at an arbitrary position on the surface of the steel sheet.
本発明は、鋼板表面の任意の位置で塗膜厚みを変えられる表面処理鋼板の製造設備およびその製造方法を提供することを目的とする。 An object of this invention is to provide the manufacturing equipment of the surface treatment steel plate which can change coating-film thickness in the arbitrary positions of the steel plate surface, and its manufacturing method.
本発明者らは、鋼板表面の任意の位置で塗膜厚みを変えられる表面処理鋼板の製造方法について鋭意研究を重ねた結果、複数のヘッドが具備された1台のインクジェット装置を用い、複数のヘッドを鋼板の幅方向に沿って配置し、塗料を、複数のヘッドから液滴として、特定のヘッドでは液適量を変えて、吐出させ、鋼板面に着地させて塗膜を形成すればよいことを見出した。 As a result of intensive studies on a method for producing a surface-treated steel sheet that can change the coating thickness at an arbitrary position on the surface of the steel sheet, the present inventors have used a single inkjet device equipped with a plurality of heads, It is only necessary to arrange the head along the width direction of the steel sheet, and form the coating film by applying paint as droplets from multiple heads, changing the appropriate amount of liquid in a specific head, discharging it, and landing on the steel sheet surface. I found.
本発明は、このような知見に基づきなされたもので、複数のヘッドが具備された1台のインクジェット装置を有し、前記インクジェット装置に具備された複数のヘッドが鋼板の幅方向に沿って配置されている表面処理鋼板の製造設備を提供する。 The present invention has been made based on such knowledge, and has one inkjet device provided with a plurality of heads, and the plurality of heads provided in the inkjet device are arranged along the width direction of the steel plate. The equipment for manufacturing the surface-treated steel sheet is provided.
本発明の製造設備では、インクジェット装置に併せて熱処理装置を備えることができる。 In the production facility of the present invention, a heat treatment apparatus can be provided in addition to the ink jet apparatus.
本発明は、また、上記の表面処理鋼板の製造設備を用い、塗料を、インクジェット装置に具備された複数のヘッドから液滴として、特定のヘッドでは液適量を変えて、吐出させ、鋼板面に着地させて塗膜を形成する表面処理鋼板の製造方法を提供する。 The present invention also uses the above-described surface-treated steel sheet manufacturing equipment, and paint is discharged as droplets from a plurality of heads provided in an ink jet apparatus, while changing the appropriate amount of liquid in a specific head and ejecting the paint onto the steel sheet surface. Provided is a method for producing a surface-treated steel sheet which is landed to form a coating film.
本発明の製造方法では、塗膜を形成後、塗膜に熱処理を施すこともできる。 In the manufacturing method of this invention, after forming a coating film, it can also heat-process a coating film.
塗料として、例えば、有機樹脂を含有し、さらに硬化剤、潤滑剤、防錆顔料および着色顔料から選ばれた少なくとも1種を配合した塗料を挙げることができる。 As the paint, for example, a paint containing an organic resin and further blended with at least one selected from a curing agent, a lubricant, a rust preventive pigment and a color pigment can be given.
本発明により、鋼板表面の任意の位置で塗膜厚みが変えられた表面処理鋼板を製造できるようになった。そのため、必要な部位のみの塗膜厚みを薄くして導電性の付与された表面処理鋼板を用いることが可能となった。したがって、スポット溶接やシーム溶接が可能になるのみならず、この表面処理鋼板を用いた製品の耐食性をほとんど低下させることなく電磁波シールド性も向上できることになる。 According to the present invention, a surface-treated steel sheet having a coating film thickness changed at an arbitrary position on the steel sheet surface can be produced. For this reason, it is possible to use a surface-treated steel sheet to which conductivity is imparted by reducing the thickness of the coating film only at necessary portions. Therefore, not only spot welding and seam welding are possible, but also the electromagnetic wave shielding property can be improved without substantially reducing the corrosion resistance of the product using the surface-treated steel sheet.
インクジェットプリンターは、インクを多数の吐出口(ノズル)を有するヘッドからピエゾ方式やサーマル方式によって微細な液滴として吐出させ、直接紙などの被印字媒体に着地させて印刷する印刷機である。本発明では、このインクジェットプリンターの技術を、主として耐食性を目的に塗膜の形成された表面処理鋼板に応用して、従来不可能であった必要な部位のみの塗膜厚みを変えることを可能にし、例えば特定の部位に導電性を付与させて溶接や電磁波シールドを可能としたことに特徴がある。 An ink jet printer is a printing machine that ejects ink as fine droplets from a head having a large number of ejection openings (nozzles) by a piezo method or a thermal method and directly lands on a print medium such as paper. In the present invention, this inkjet printer technology is applied to a surface-treated steel sheet with a coating film formed mainly for the purpose of corrosion resistance, and it is possible to change the coating thickness only at the necessary site, which was impossible in the past. For example, it is characterized in that welding or electromagnetic wave shielding is made possible by imparting conductivity to a specific part.
図1に本発明の表面処理鋼板の製造設備の一例を示す。この例では、1台のインクジェット装置(図示せず)が設置されており、インクジェット装置に具備された複数のヘッド11が、鋼板面の鉛直方向上方に、鋼板の幅方向に沿って配置されている。このとき、インクジェット装置に具備された複数のヘッド11は、図2に6個のヘッド11a〜fの場合を示したが、鋼板10の幅方向に沿ってちどり配置されることが、塗膜厚みを制御する上で好ましい。また、図1および図2においては、ほぼ水平な鋼板面に対して鉛直方向上方に複数のヘッドを配置する場合を示したが、鋼板面が鉛直方向にほぼ平行となっている場合は、各ヘッドから吐出する塗料の液滴が鋼板面に着地し、塗膜を形成できる位置に各ヘッドを配置すればよい。
FIG. 1 shows an example of equipment for producing the surface-treated steel sheet of the present invention. In this example, one inkjet device (not shown) is installed, and a plurality of
本発明の製造設備で使用するインクジェット装置には、市販のインクジェットプリンターと同様なものが適用できるが、表面処理鋼板のような大面積上への塗膜形成を対象としているので、鋼板のサイズによって塗料供給系の容量やヘッドのサイズ、数などを適宜変更できることが好ましい。 Although the same thing as a commercially available ink jet printer can be applied to the ink jet device used in the production facility of the present invention, since it is intended for coating film formation on a large area such as a surface-treated steel plate, depending on the size of the steel plate It is preferable that the capacity of the coating material supply system, the size and number of heads, and the like can be changed as appropriate.
図1で、いま、塗料21を、図2に示したように配置された6個のヘッド11a〜fからなるヘッド11から液滴として吐出させ、鋼板10面に着地させる際に、6個のヘッド11a〜fのうち特定のヘッド、例えばヘッド11eと他のヘッド11a〜d、fから吐出される液適量を変えれば、ヘッド11eを通過した部位と他のヘッドの11a〜d、fを通過した部位で厚みが異なる塗膜を形成できる。このようにして、液滴量を変えるヘッドを経時的に適宜選択していけば、鋼板表面の任意の位置で厚みの異なる塗膜を形成できることになる。さらに、液適量自体をヘッドごとにあるいは経時的に変えれば、鋼板表面の任意の位置で任意の厚みを有する塗膜を形成できることになる。このとき、ヘッドの液適量を変えるには、各ヘッドで使用するノズル数やノズルから吐出させる液滴の間隔(周波数)を変えればよい。
In FIG. 1, now, when the
インクジェット装置に併せて熱処理装置を備えることにより塗膜形成後塗膜に加熱処理を施すこともできる。 By providing a heat treatment device in combination with the ink jet device, the coating film can be subjected to heat treatment after the coating film is formed.
また、図3に示すように、ロール31、32などを用いて鋼板10の進行方向を変え、ヘッド11と、ヘッドの位置より下流側に熱処理装置40を配置すれば、鋼板10の表裏面に塗膜を形成でき、さらに熱処理を施すこともできる。
Also, as shown in FIG. 3, if the direction of travel of the
本発明は、例えば、有機樹脂含有し、さらに硬化剤、潤滑剤、防錆顔料および着色顔料から選ばれた少なくとも1種を配合した塗料を用いて塗膜の形成された表面処理鋼板に適用できる。こうした表面処理鋼板では、通常、塗膜厚みは1〜20μmであるが、溶接が行われる部位や電磁波シールド性の必要な部位では、本発明の方法により塗膜厚みを1μm以下にして導電性を持たせることができる。 The present invention can be applied to, for example, a surface-treated steel sheet that contains an organic resin, and further has a coating film formed using a paint that contains at least one selected from a curing agent, a lubricant, a rust preventive pigment, and a color pigment. . In such a surface-treated steel sheet, the coating thickness is usually 1 to 20 μm. However, in the site where welding is performed or where electromagnetic shielding is necessary, the coating thickness is reduced to 1 μm or less by the method of the present invention. You can have it.
板厚0.7mm、板幅200mmの電気亜鉛めっき鋼板(片面当たりのめっき付着量:20g/m2)に、図2に示すように鋼板の幅方向に6個のヘッド11a〜fをちどり配置したヘッドを具備するインクジェット装置を用いて、エポキシ樹脂[ジャパンエポキシレジン(株)製エピコート(登録商標)1007]と硬化剤としてトリレンジイソシアネート[日本ポリウレタン工業(株)製コロネート(登録商標)2507]を質量比70/30で含む塗料の液滴を、ヘッド11a〜d、fとヘッド11eとで液適量を変えて吐出させ、鋼板面に着地させた後、高周波誘導加熱炉で140℃に加熱し、図4に示すような厚膜部と薄膜部を有する塗膜の形成された表面処理鋼板No.1〜7を作製した。このとき、ヘッド11a〜fの先端は鋼板面から2mmの高さにあり、鋼板の移動速度は10m/minである。ヘッド11a〜fは、いずれもピエゾ方式で液滴を形成するタイプであり、それぞれ幅36mmの中に512本のノズルが、ノズル間距離70.5μmで配列されている。また、表1に示すように、ヘッド11a〜d、fのノズルから吐出される塗料の液適量を42pL(ピコリットル)とし、周波数を0.5〜9.5kHzに変えて厚みを1.25〜20μmとした厚膜部と、ヘッド11eのノズルから塗料を吐出させないで厚みを0μmとした薄膜部(No.1〜4)あるいはヘッド11eのノズルから吐出される塗料の液適量を42pLとし、周波数を0.14〜0.45kHzに変えて厚みを0.3〜0.9μmとした薄膜部(No.5〜7)とからなる塗膜を形成した。 As shown in Fig. 2, six heads 11a-f are arranged in the direction of the width of the steel sheet on an electrogalvanized steel sheet with a thickness of 0.7mm and a width of 200mm (plating adhesion amount per side: 20g / m 2 ). Using an inkjet apparatus equipped with a head, epoxy resin [Epicoat (registered trademark) 1007 manufactured by Japan Epoxy Resin Co., Ltd.] and tolylene diisocyanate [Coronate (registered trademark) 2507 manufactured by Nippon Polyurethane Industry Co., Ltd.] Liquid droplets of paint containing at a mass ratio of 70/30 are ejected by changing the appropriate amount of liquid between the heads 11a to d, f and the head 11e, landed on the steel plate surface, and then heated to 140 ° C in a high frequency induction heating furnace. Surface-treated steel sheets No. 1 to 7 having a coating film having a thick film part and a thin film part as shown in FIG. 4 were produced. At this time, the tips of the heads 11a to f are at a height of 2 mm from the steel plate surface, and the moving speed of the steel plate is 10 m / min. Each of the heads 11a to 11f is of a type that forms droplets by a piezo method, and 512 nozzles are arranged in a width of 36 mm with a distance between nozzles of 70.5 μm. Also, as shown in Table 1, the appropriate amount of paint discharged from the nozzles of the heads 11a to d, f is 42 pL (picoliter), the frequency is changed to 0.5 to 9.5 kHz, and the thickness is 1.25 to 20 μm. The film and the thin film portion (No. 1 to 4) whose thickness is 0 μm without discharging the paint from the nozzle of the head 11e or the liquid amount of the paint discharged from the nozzle of the head 11e is 42 pL, and the frequency is 0.14 to 0.45. A coating film comprising a thin film part (No. 5 to 7) having a thickness of 0.3 to 0.9 μm was formed in place of kHz.
また、上記と同じ塗料を、従来法であるロールコーターにより塗布後、高周波誘導加熱炉で140℃に加熱し、表2に示すように、厚み0.3〜20μmの塗膜を形成した表面処理鋼板No.8〜14を作製した。 In addition, after applying the same paint as described above with a conventional roll coater, it was heated to 140 ° C. in a high-frequency induction heating furnace, and as shown in Table 2, a surface-treated steel sheet No. having a coating film having a thickness of 0.3 to 20 μm was formed. .8-14 were produced.
そして、本発明法で作製した表面処理鋼板No.1〜7の厚膜部と薄膜部と従来法であるロールコーターにより作製した表面処理鋼板No.8〜14について、塗膜厚み、耐白錆性、導電性を以下の方法で調査した。 And about the surface treatment steel plate No.8-14 produced by the thick film part and thin film part of the surface treatment steel plate No.1-7 produced by the method of the present invention, and the conventional roll coater, the coating thickness, white rust resistance The properties and conductivity were investigated by the following methods.
塗膜厚み:皮膜断面のSEM観察により測定した。 Film thickness: measured by SEM observation of the film cross section.
耐白錆性:表面処理鋼板1〜7の厚膜部と表面処理鋼板8〜14について、塩水噴霧試験(JIS-Z-2371-2000)を施し、48時間後の白錆面積率を測定し、以下のように評価した。
◎:白錆発生面積率5%未満
○:白錆発生面積率5%以上10%未満
○−:白錆発生面積率10%以上25%未満
△:白錆発生面積率25%以上50%未満
×:白錆発生面積率50%以上
導電性:表面処理鋼板1〜7の薄膜部と表面処理鋼板8〜14について、使用電極:CF型Cr-Cu電極(先端径:5.5mmφ)、加圧力:196N(200kgf)、通電時間:10サイクル/50Hz、溶接電流:10kAの条件で連続打点性の溶接試験を行い、連続打点数を求め、以下のように評価した。
◎:2000点以上
○:1000点以上2000点未満
△:500点以上1000点未満
×:500点未満
本発明法で作製した表面処理鋼板No.1〜7の結果を表1に、また、従来法であるロール作製した表面処理鋼板No.8〜14の結果を表2に示す。本発明法で作製した表面処理鋼板No.1〜7では、いずれも導電性に優れた薄膜部と耐食性に優れた厚膜部を具備しており、鋼板表面の任意の位置で塗膜厚みを変えられるという本発明の特徴が生かされていることがわかる。一方、従来法であるロールコーターにより作製した表面処理鋼板8〜14では、鋼板表面の任意の位置で塗膜厚みを変えることができないため、厚みが厚いと耐食性に優れるが、導電性に劣り、厚みが薄いと導電性に優れるが、耐食性に劣り、耐食性と導電性の両特性を具備した鋼板は得られない。
White rust resistance: A salt spray test (JIS-Z-2371-2000) was performed on the thick film part of the surface-treated steel sheets 1 to 7 and the surface-treated steel sheets 8 to 14, and the white rust area ratio after 48 hours was measured. The evaluation was as follows.
◎: White rust generation area ratio 5% or less ○: White rust generation area ratio 5% or more and less than 10% ○-: White rust
◎: More than 2000 points ○: More than 1000 points and less than 2000 points △: More than 500 points and less than 1000 points ×: Less than 500 points Table 1 shows the results of surface-treated steel sheets Nos. 1 to 7 produced by the method of the present invention. Table 2 shows the results of the surface-treated steel sheets No. 8 to 14 produced by the roll method. The surface-treated steel sheets Nos. 1 to 7 produced by the method of the present invention each have a thin film part excellent in conductivity and a thick film part excellent in corrosion resistance. It can be seen that the feature of the present invention that it can be changed is utilized. On the other hand, in the surface-treated steel sheets 8 to 14 produced by a conventional roll coater, the coating thickness cannot be changed at any position on the steel sheet surface, so the thickness is excellent for corrosion resistance, but the conductivity is inferior, If the thickness is small, the electrical conductivity is excellent, but the corrosion resistance is inferior, and a steel sheet having both corrosion resistance and electrical conductivity cannot be obtained.
