Description

容器用鋼板Steel plate for containers 技術領域Technical field

本發明係有關於一種可作為製罐加工用原料之容器用鋼板，特別是有關於一種沖壓拉伸加工(drawing and ironing process)、焊接性、抗蝕性、塗料密接性及膜密接性優異之容器用鋼板。The present invention relates to a steel sheet for containers which can be used as a raw material for can processing, and particularly relates to a drawing and ironing process, weldability, corrosion resistance, paint adhesion, and film adhesion. Steel plate for containers.

背景技術Background technique

用於飲料或食品等之金屬容器可大致區分成2片罐及3片罐。以DI罐為代表之2片罐係在進行沖壓拉伸加工後，在罐內面側進行塗裝，並在罐外面側進行塗裝及印刷。另外，3片罐係在相當於罐內面之面進行塗裝，並在相當於罐外面側之面進行印刷後，再進行罐身之焊接。Metal containers for beverages or foods can be roughly divided into two-piece cans and three-piece cans. A two-piece can represented by a DI can is subjected to press drawing processing, and then coated on the inner surface side of the can, and coated and printed on the outer side of the can. Further, the three-piece can was coated on the surface corresponding to the inner surface of the can, and printed on the surface corresponding to the outer surface of the can, and then the can body was welded.

不論是哪一種罐，都必須在製罐前後進行塗裝步驟。塗裝可使用溶劑系或水系塗料，之後再進行烘烤。在該塗裝步驟中，因塗料產生之廢棄物(廢溶劑等)係作為產業廢棄物排出，而排放氣體(主要為碳酸氣)則釋出至大氣中。近年，正進行以保護地球環境為目的，使該等產業廢棄物或排放氣體等減低的對策。其中，以膜貼合來取代塗裝的技術正備受矚目而急速擴展。Regardless of the type of can, the coating step must be performed before and after canning. A solvent-based or water-based paint can be used for the coating, followed by baking. In the coating step, waste (dissolved solvent, etc.) generated by the paint is discharged as industrial waste, and exhaust gas (mainly carbonic acid gas) is released into the atmosphere. In recent years, measures are being taken to reduce such industrial wastes or exhaust gases for the purpose of protecting the global environment. Among them, the technology of replacing the coating with film bonding is attracting attention and rapidly expanding.

目前為止，關於2片罐方面，已提供了不少將膜貼合來進行製罐之製罐方法或與其相關之發明等。例如，關於沖壓拉伸罐之製造方法係揭示於如專利文獻1中。另外，關於沖壓拉伸罐(drawn and ironed can)係揭示於如專利文獻2中。此外，關於薄型深沖壓罐(deep drawn can)之製造方法係揭示於如專利文獻3中。又，關於沖壓拉伸罐用被覆鋼板則揭示於如專利文獻4中。Heretofore, regarding the two-piece can, a number of methods for forming a can to form a can or a related invention have been provided. For example, a manufacturing method of a press-drawn can is disclosed as in Patent Document 1. Further, a drawn and ironed can is disclosed as in Patent Document 2. Further, a method of manufacturing a deep drawn can is disclosed in Patent Document 3, for example. Moreover, the coated steel sheet for a press-drawn can is disclosed in Patent Document 4, for example.

另外，在3片罐方面，三片罐用膜積層鋼帶及其製造方法係揭示於如專利文獻5中。另外，關於罐外面具有多層有機薄膜之三片罐用鋼板係揭示於如專利文獻6中。此外，關於具有條狀多層有機薄膜之三片罐用鋼板係揭示於如專利文獻7中。又，關於3片罐條狀積層鋼板之製造方法則揭示於如專利文獻8中。Further, in the case of a 3-piece can, a film-layered steel strip for a three-piece can and a method for producing the same are disclosed in Patent Document 5. Further, a steel sheet for a three-piece can having a multilayer organic film on the outside of the can is disclosed in Patent Document 6. Further, a steel sheet for a three-piece can having a strip-shaped multilayer organic film is disclosed in Patent Document 7. Further, a method for producing a three-piece can-shaped laminated steel sheet is disclosed in Patent Document 8.

另一方面，在積層膜之底材所用之鋼板上，大多使用經電解鉻酸處理後之鉻酸薄膜。鉻酸薄膜具有2層結構，金屬Cr層的上層有水合氧化Cr層存在。因此，積層膜(若是具有接著劑之膜則為接著層)可透過鉻酸薄膜之水合氧化Cr層來確保與鋼板之密接性。雖然關於該顯現密接性之機構的詳細情形尚未明確，但可說是水合氧化Cr之氫氧基與積層膜之羰基或酯基等之官能基的氫結合。On the other hand, a chromic acid film treated with electrolytic chromic acid is often used on the steel sheet used for the substrate of the laminated film. The chromic acid film has a two-layer structure, and the upper layer of the metal Cr layer has a hydrated oxidized Cr layer. Therefore, the laminated film (in the case of a film having an adhesive agent, it is an adhesive layer) can be oxidized by the chromic acid film to oxidize the Cr layer to ensure adhesion to the steel sheet. Although the details of the mechanism for exhibiting the adhesion are not clear, it can be said that the hydroxyl group of the hydrated oxidized Cr is bonded to the hydrogen of a functional group such as a carbonyl group or an ester group of the laminate film.

前述發明的確可以得到使地球環境的保護大有進展的效果，但另一方面，近年在飲料容器市場上，PET瓶、瓶子、紙等原料間之成本及品質的競爭愈演愈烈，對於前述積層容器用鋼板來說，不僅要確保對於習知技術之塗裝用途之優異密接性、抗蝕性，還需要更加優異之製罐加工性，特別是膜密接性、加工膜密接性、抗蝕性等。The above invention can indeed achieve the effect of greatly improving the protection of the global environment. On the other hand, in recent years, in the beverage container market, the competition between the cost and quality of raw materials such as PET bottles, bottles, and papers has intensified, and the above-mentioned laminated containers are used. In the steel sheet, it is necessary to ensure excellent adhesion to the coating application of the prior art and corrosion resistance, and further excellent can processing properties, particularly film adhesion, film adhesion, corrosion resistance, and the like.

實施發明之最佳形態Best form for implementing the invention

以下詳細地說明焊接性、製罐加工性、外觀優異之本發明之容器用鋼板之實施形態。Hereinafter, an embodiment of the steel sheet for a container of the present invention excellent in weldability, potability, and appearance will be described in detail.

本發明所用之原板並未特別限定，通常係使用可作為容器材料來使用之鋼板。而該原板之製造方法，材質等也未特別限定、可從一般之鋼片製造步驟經由熱軋、酸洗、冷軋、退火、平整等步驟製造。鋼板表面披覆有金屬表面處理層，且關於其披覆方法並未特別限定，例如可使用電鍍法、真空蒸鍍法或濺鍍法等公知技術，亦可與用以披覆擴散層之加熱處理組合。The original sheet used in the present invention is not particularly limited, and a steel sheet which can be used as a container material is usually used. The method for producing the original sheet, the material, and the like are not particularly limited, and can be produced from a general steel sheet manufacturing step by hot rolling, pickling, cold rolling, annealing, and flattening. The surface of the steel sheet is coated with a metal surface treatment layer, and the coating method is not particularly limited. For example, a known technique such as an electroplating method, a vacuum evaporation method, or a sputtering method, or a heating method for coating the diffusion layer may be used. Process the combination.

在本實施形態中，金屬表面處理層之一形態係鋼板表面上形成有含有5mg/m2 ~150mg/m2 之Ni的Ni鍍層或含有5mg/m2 ~150mg/m2 之Ni的Fe－Ni合金鍍層，且其上還形成有300mg/m2 ~3000mg/m2 之鍍Sn；一部分或全部之底材Ni層及Sn鍍層之一部分係藉由熔融熔錫處理而合金化，且殘留一部分之金屬Sn鍍層。In this embodiment, Ni is formed containing 5mg / m 2 ~ 150mg / m 2 of Ni plating or the containing Fe- 5mg / m 2 ~ 150mg / m Ni on the steel sheet surface 2 of the metal surface treatment layer forms one line a Ni alloy plating layer on which 300 mg/m 2 to 3000 mg/m 2 of Sn plating is formed; part or all of the substrate Ni layer and one part of the Sn plating layer are alloyed by melt-melting treatment, and a part remains. Metal Sn plating.

在鋼板上進行鍍Ni或Fe－Ni合金之鍍Ni系，以披覆Ni系鍍層的目的在於確保抗蝕性。因Ni為高抗蝕金屬，故藉由將Ni鍍在鋼板表面上，可提高於熔融熔錫處理時所形成之合金層的抗蝕性。由於因Ni所產生之合金層抗蝕性提高效果要在所鍍之Ni量在5mg/m2 以上後才會開始顯現，所以Ni量必須要在5mg/m2 以上。合金層之抗蝕性提高效果會隨Ni量的增多而增加，但當該Ni量大於150mg/m2 時，其提高效果就會飽和。另外，因Ni係高價金屬，若鍍上150mg/m2 以上之Ni在經濟上也不划算。因此，Ni量必須控制在5mg/m2 ~150mg/m2 。A Ni-plated Ni or Fe-Ni alloy-plated Ni-based system is applied to the steel sheet to coat the Ni-based plating layer for the purpose of ensuring corrosion resistance. Since Ni is a high-resistance metal, by plating Ni on the surface of the steel sheet, the corrosion resistance of the alloy layer formed during the molten tin-melting treatment can be improved. Since the effect of improving the corrosion resistance of the alloy layer by Ni is not started until the amount of Ni plated is 5 mg/m 2 or more, the amount of Ni must be 5 mg/m 2 or more. The effect of improving the corrosion resistance of the alloy layer increases as the amount of Ni increases, but when the amount of Ni is more than 150 mg/m 2 , the effect of the improvement is saturated. Further, it is not economically economical to plate Ni with a high-valent Ni-based metal of 150 mg/m 2 or more. Therefore, the amount of Ni must be controlled at 5 mg/m 2 to 150 mg/m 2 .

此外，在使Ni擴散層形成時，係在鍍Ni後以退火爐進行擴散處理，來形成Ni擴散層，即使在Ni擴散處理的前後或同時進行氮化處理，也可發揮本發明之Ni系鍍層之Ni的效果及氮化處理層的效果。一般而言，鍍Ni及鍍Fe－Ni合金的方法可使用藉由電鍍法進行之公知方法。Further, when the Ni diffusion layer is formed, Ni plating is performed in an annealing furnace after Ni plating, and a Ni diffusion layer is formed, and the Ni system of the present invention can be exhibited even before or after the Ni diffusion treatment. The effect of Ni on the plating layer and the effect of the nitrided treatment layer. In general, a method of plating Ni and plating an Fe-Ni alloy can use a known method by electroplating.

接著，在鍍Ni系後進行鍍Sn。此處所說之鍍Sn係指使用金屬Sn來鍍，而不可避免地會有雜質混入的情形，也會有添加微量元素的情形。關於鍍Sn的方法並未特別限定，只要使用公知之電鍍法或浸漬於熔融之Sn中再鍍上去的方法等即可。鍍Sn的目的在於確保抗蝕性和焊接性。Sn本身即具有高抗蝕性，因此不論是金屬Sn，還是下述之藉由熔融熔錫處理形成之合金Sn，皆可發揮優異之抗蝕性。這種Sn之優異之抗蝕性在300mg/m2 以上後就顯著地提高，且抗蝕性會隨Sn鍍量的增多而提高，但在3000mg/m2 以上時，其效果就會飽和。因此，從經濟上的觀點來看，Sn之鍍量最好是控制在3000mg/m2 以下。Next, Sn plating is performed after Ni plating. The term "Sn plating" as used herein refers to a case where plating is performed using metal Sn, and inevitably, impurities may be mixed, and a trace element may be added. The method of plating Sn is not particularly limited, and any known plating method or a method of immersing in molten Sn and plating it may be used. The purpose of plating Sn is to ensure corrosion resistance and weldability. Since Sn itself has high corrosion resistance, excellent corrosion resistance can be exhibited regardless of the metal Sn or the alloy Sn formed by the molten tin treatment described below. The excellent corrosion resistance of such Sn is remarkably improved after 300 mg/m 2 or more, and the corrosion resistance increases as the amount of Sn plating increases, but when it is 3000 mg/m 2 or more, the effect is saturated. Therefore, from the economic point of view, the amount of Sn plating is preferably controlled to be 3000 mg/m 2 or less.

另外，電阻低之Sn較軟，藉由在焊接時將Sn於電極間加壓可使其延展，確保安定之通電域，而可發揮特別優異之焊接性。只要金屬Sn量在100mg/m2 以上，即可發揮這種優異之焊接性。此外，只要在本發明之Sn鍍量的範圍，便不需要規定金屬Sn量的上限量。因此，考慮上述2點，而將Sn鍍量限制在300mg/m2 ~3000mg/m2 的範圍。Further, Sn having a low electric resistance is soft, and Sn can be extended by pressurizing between the electrodes during welding to ensure a stable energization region, and particularly excellent weldability can be exhibited. As long as the amount of the metal Sn is 100 mg/m 2 or more, such excellent weldability can be exhibited. Further, as long as it is in the range of the Sn plating amount of the present invention, it is not necessary to define the upper limit amount of the amount of metal Sn. Therefore, considering the above two points, the amount of Sn plating is limited to the range of 300 mg/m 2 to 3000 mg/m 2 .

在鍍Sn後，進行熔融熔錫處理。進行熔融熔錫處理的目的在於熔融Sn，使其與底材鋼板或底材金屬等合金化，形成Sn－Fe或Sn－Fe－Ni合金層，以提高合金層之抗蝕性，並使一部分之金屬Sn殘留下來。金屬錫之殘留形態有島狀、水池狀、條狀等各種形態。藉由控制該熔融熔錫處理，即可得到具有一部分之金屬Sn殘留，而一部分之塗料及膜密接性優異之Sn－Ni或Fe－Ni－Sn合金鍍層露出之鍍結構的鋼板。After the Sn plating, a molten tinning treatment is performed. The purpose of performing the molten tinning treatment is to melt Sn and alloy it with a substrate steel plate or a substrate metal to form a Sn-Fe or Sn-Fe-Ni alloy layer to improve the corrosion resistance of the alloy layer and to partially The metal Sn remains. The residual form of the metallic tin has various forms such as an island shape, a pool shape, and a strip shape. By controlling the molten tin treatment, a steel sheet having a plating structure in which a part of the metal Sn remains and a part of the coating and the Sn-Ni or Fe-Ni-Sn alloy plating layer having excellent film adhesion is exposed can be obtained.

另外，本發明之金屬表面處理層之另一形態有鋼板表面上形成有含有560mg/m2 ~5600mg/m2 之鍍Sn，Sn鍍層之一部分係藉由熔融熔錫處理而合金化者。Sn雖具有優異之加工性、優異之焊接性及抗蝕性，但在只鍍Sn時，由抗蝕性的點來看，必須在560mg/m2 以上。雖抗蝕性會隨鍍Sn量的增多而提高，但在5600mg/m2 以上時，其效果就會飽和。因此，從經濟上的觀點來看，Sn之鍍量最好是控制在5600mg/m2 以下。又，藉由在鍍Sn後進行熔融熔錫處理，可形成Sn合金層，更加提高抗蝕性Further, another aspect of the present invention a metal surface treated with a layer of Ownership containing 560mg / m 2 ~ 5600mg / m of plated Sn 2, Sn-based plating layer portion of the tin melting treatment by alloying the steel sheet surface is formed. Sn has excellent workability, excellent weldability, and corrosion resistance. However, when Sn is only plated, it is necessary to be 560 mg/m 2 or more from the viewpoint of corrosion resistance. Although the corrosion resistance increases as the amount of plating Sn increases, the effect is saturated at 5600 mg/m 2 or more. Therefore, from the economical point of view, the amount of Sn plating is preferably controlled to be 5600 mg/m 2 or less. Further, by performing a molten tinning treatment after Sn plating, a Sn alloy layer can be formed, and corrosion resistance can be further improved.

這些金屬表面處理層之上層披覆有Zr薄膜、磷酸薄膜、酚樹脂薄膜中之2種以上。The upper surface of the metal surface treatment layer is coated with two or more of a Zr film, a phosphoric acid film, and a phenol resin film.

雖然Zr薄膜、磷酸薄膜、酚樹脂薄膜即使單獨使用也具有某種程度之效果，但並不具充分的實用性能。但是，複合有Zr薄膜、磷酸薄膜、酚樹脂薄膜中之2種以上的薄膜可發揮優異之實用性能。此外，若將Zr薄膜複合磷酸薄膜或酚樹脂薄膜之1種以上，可發揮更加優異之實用性能。而且，在薄膜量少的範圍中，因互補各個特性，複合有Zr薄膜、磷酸薄膜、酚樹脂薄膜之3種的薄膜具有更安定之實用性能。此外，同一薄膜內混合有Zr、磷酸系化合物、酚等中之2種以上的薄膜，與個別形成Zr薄膜、磷酸薄膜、酚樹脂薄膜之2種以上的情形相比，抗蝕性、密接性等實用性能較不佳。其理由尚未明確，但一般認為是由於在同一薄膜內混合Zr、磷酸系化合物、酚，而妨礙各個成分發揮性能。Although the Zr film, the phosphoric acid film, and the phenol resin film have a certain effect even when used alone, they do not have sufficient practical properties. However, two or more types of films of a Zr film, a phosphoric acid film, and a phenol resin film are combined to exhibit excellent practical properties. In addition, when one or more types of Zr film composite phosphoric acid film or phenol resin film are used, more excellent practical performance can be exhibited. Further, in the range where the amount of the film is small, three types of films in which a Zr film, a phosphoric acid film, and a phenol resin film are combined have a more stable practical performance due to the complementary characteristics. In addition, two or more kinds of films of Zr, a phosphoric acid compound, and a phenol are mixed in the same film, and corrosion resistance and adhesion are compared with those of two or more types of Zr film, phosphoric acid film, and phenol resin film. Such practical performance is not good. Although the reason for this is not clear, it is considered that the Zr, the phosphate compound, and the phenol are mixed in the same film, and the performance of each component is hindered.

Zr薄膜的功用在於確保抗蝕性和密接性。Zr薄膜係由氧化Zr、氫氧化Zr、氟化Zr、磷酸Zr等Zr化合物或其複合薄膜構成。該等Zr化合物具有優異之抗蝕性和密接性。因此，當Zr薄膜增加時，抗蝕性或密接性等就會開始提高，當金屬Zr量在1mg/m2 以上時，即可確保實用上沒有問題之程度的抗蝕性和密接性。而，當Zr薄膜再增加時，抗蝕性或密接性之提高效果也會增加，但Zr薄膜量之金屬Zr量大於500mg/m2 時，Zr薄膜就會過厚，使Zr薄膜本體之密接性劣化，並且電阻會上升，而使焊接性劣化。因此，Zr薄膜量之金屬Zr量需要控制在1mg/m2 ~500mg/m2 。The function of the Zr film is to ensure corrosion resistance and adhesion. The Zr film is composed of a Zr compound such as Zr oxide, Zr hydroxide, fluorinated Zr or phosphoric acid Zr or a composite film thereof. These Zr compounds have excellent corrosion resistance and adhesion. Therefore, when the Zr film is increased, the corrosion resistance, the adhesion, and the like are started to increase. When the amount of the metal Zr is 1 mg/m 2 or more, the corrosion resistance and the adhesion property to the extent that there is no practical problem can be ensured. However, when the Zr film is further increased, the effect of improving the corrosion resistance or the adhesion is also increased. However, when the amount of the Zr film of the Zr film is more than 500 mg/m 2 , the Zr film is too thick, so that the Zr film body is closely connected. The property is deteriorated, and the electric resistance is increased to deteriorate the weldability. Therefore, the amount of metal Zr of the Zr film amount needs to be controlled to be 1 mg/m 2 to 500 mg/m 2 .

另外，當Zr薄膜量之金屬Zr量大於15mg/m2 時，薄膜之附著不均(mura)就會顯現為外觀上之不均，故Zr薄膜量之金屬Zr量以1mg/m2 ~15mg/m2 較佳。而且，為使外觀上之不均更良好安定化，Zr薄膜量中之金屬Zr量以0.1mg/m2 ~9mg/m2 更佳。In addition, when the amount of the metal Zr of the Zr film amount is more than 15 mg/m 2 , the uneven adhesion of the film (mura) appears to be uneven in appearance, so the amount of the metal Zr of the Zr film amount is 1 mg/m 2 to 15 mg. /m 2 is preferred. Further, in order to make the appearance unevenness more stable, the amount of the metal Zr in the amount of the Zr film is preferably from 0.1 mg/m 2 to 9 mg/m 2 .

磷酸薄膜的功用為確保抗蝕性和密接性。磷酸薄膜係由與底材反應而形成之由磷酸Fe、磷酸Sn、磷酸Ni、磷酸Zr或磷酸酚樹脂薄膜等薄膜或是其複合薄膜構成。該等磷酸薄膜具有優異之抗蝕性和密接性。因此，當磷酸薄膜增加時，抗蝕性或密接性等就會開始提高，當P量在0.1mg/m2 以上時，即可確保實用上沒有問題之程度的抗蝕性和密接性。而，當磷酸薄膜再增加時，抗蝕性或密接性之提高效果也會增加，但磷酸薄膜量之P量大於100mg/m2 時，磷酸薄膜就會過厚，使磷酸薄膜本體之密接性劣化，並且電阻會上升，而使焊接性劣化。因此，磷酸薄膜量之P量需要控制在0.1mg/m2 ~100mg/m2 。The function of the phosphoric acid film is to ensure corrosion resistance and adhesion. The phosphoric acid film is formed of a film of phosphoric acid Fe, phosphoric acid Sn, phosphoric acid Ni, phosphoric acid Zr or a phosphate phenol resin film or a composite film formed by reaction with a substrate. These phosphoric acid films have excellent corrosion resistance and adhesion. Therefore, when the phosphoric acid film is increased, the corrosion resistance, the adhesion, and the like are started to increase. When the amount of P is 0.1 mg/m 2 or more, the corrosion resistance and the adhesion property to the extent that there is no practical problem can be ensured. On the other hand, when the phosphoric acid film is further increased, the effect of improving the corrosion resistance or the adhesion is also increased. However, when the amount of the phosphoric acid film is more than 100 mg/m 2 , the phosphoric acid film is too thick to make the phosphoric acid film body adhere. Deterioration, and the resistance rises, and the weldability is deteriorated. Therefore, the amount of P in the phosphoric acid film amount needs to be controlled to be 0.1 mg/m 2 to 100 mg/m 2 .

另外，當磷酸薄膜量之P量大於15mg/m2 時，薄膜之附著不均就會顯現為外觀上之不均，故磷酸薄膜量之P量以0.1mg/m2 ~15mg/m2 較佳。而且，為使外觀上之不均更良好安定化，磷酸薄膜量中之P量以0.1mg/m2 ~8mg/m2 更佳。Further, when the amount of P of the phosphoric acid film is more than 15 mg/m 2 , the uneven adhesion of the film appears to be uneven in appearance, so the amount of P of the phosphoric acid film is 0.1 mg/m 2 to 15 mg/m 2 . good. Further, in order to make the appearance unevenness more stable, the amount of P in the phosphoric acid film amount is more preferably 0.1 mg/m 2 to 8 mg/m 2 .

酚樹脂薄膜的功用為確保密接性。酚樹脂本身即為有機物，因此具有非常優異之與塗料或積層膜等之密接性。因此，當酚樹脂薄膜增加時，密接性等就會開始提高，當C量在0.1mg/m2 以上時，即可確保實用上沒有問題之程度的密接性。而，當酚樹脂薄膜再增加時，密接性之提高效果也會增加，但酚樹脂薄膜量之C量大於100mg/m2 時，電阻就會上升，而使焊接性劣化。因此，酚樹脂薄膜量之C量需要控制在0.1mg/m2 ~100mg/m2 。The function of the phenol resin film is to ensure adhesion. Since the phenol resin itself is an organic substance, it has excellent adhesion to a coating material or a laminated film. Therefore, when the phenol resin film is increased, the adhesion and the like are started to increase, and when the amount of C is 0.1 mg/m 2 or more, the adhesion to the extent that there is no practical problem can be ensured. On the other hand, when the phenol resin film is further increased, the effect of improving the adhesion is also increased. However, when the amount of C of the phenol resin film is more than 100 mg/m 2 , the electric resistance is increased and the weldability is deteriorated. Therefore, the amount of C of the phenol resin film amount needs to be controlled to be 0.1 mg/m 2 to 100 mg/m 2 .

另外，當酚樹脂薄膜量之C量大於15mg/m2 時，薄膜之附著不均就會顯現為外觀上之不均，故酚樹脂薄膜量之C量以0.1mg/m2 ~15mg/m2 較佳。而且，為了更減少外觀上之不均，使其良好安定化，酚樹脂薄膜量之C量以0.1mg/m2 ~8mg/m2 更佳。Further, when the amount of C of the phenol resin film is more than 15 mg/m 2 , the uneven adhesion of the film appears to be uneven in appearance, so the amount of C of the phenol resin film is 0.1 mg/m 2 to 15 mg/m. 2 is preferred. Further, in order to further reduce the unevenness in appearance and to make it stable, the amount of C of the phenol resin film is preferably from 0.1 mg/m 2 to 8 mg/m 2 .

披覆該等薄膜的方法有將鋼板浸漬於溶解有Zr離子、磷酸離子、低分子之酚樹脂之酸性溶液中的方法，或藉由陰極電解處理來進行的方法。因浸漬處理係對底材進行蝕刻來形成各種薄膜，故附著會不均一。另外，因處理時間較長，故在工業生產上較為不利。另一方面，陰極電解處理係因強制性之電荷移動及產生於鋼板界面之氫所引起之表面清淨化、與因pH上升所引起之加速附著效果相輔相承，而可在數秒到數十秒左右的短時間內處理好均一的薄膜，所以在工業上極為有利。因此，最好是利用陰極電解處理來披覆本發明之Zr薄膜、磷酸薄膜、酚樹脂薄膜。The method of coating the films is a method of immersing the steel sheet in an acidic solution in which Zr ions, phosphate ions, and low molecular phenol resins are dissolved, or a method of performing cathodic electrolysis. Since the immersion treatment etches the substrate to form various films, adhesion may be uneven. In addition, because of the long processing time, it is disadvantageous in industrial production. On the other hand, the cathodic electrolysis treatment is complementary to the surface cleaning caused by the forced charge movement and the hydrogen generated at the interface of the steel sheet, and the accelerated adhesion effect due to the pH rise, and can be in the range of several seconds to several tens A uniform film is handled in a short time of about seconds, so it is extremely advantageous industrially. Therefore, it is preferable to coat the Zr film, the phosphoric acid film, and the phenol resin film of the present invention by cathodic electrolysis treatment.

此外，在浸漬處理或陰極電解處理等所使用之酸性溶液中添加鞣酸時，鞣酸會與Fe結合，在表面形成鞣酸Fe的薄膜，有提高抗鏽性或密接性等的效果。因此，亦可依用途，在添加有鞣酸之溶液中進行。Further, when citric acid is added to an acidic solution used for immersion treatment or cathodic electrolysis treatment, tannic acid is bonded to Fe to form a film of bismuth citrate on the surface, which has an effect of improving rust resistance, adhesion, and the like. Therefore, it can also be carried out in a solution to which citric acid is added depending on the application.
