Description

鉛酸蓄電池及鉛酸蓄電池的端子防鏽方法Lead-acid battery and method for preventing rust of lead-acid battery terminal

本發明，係關於鉛酸蓄電池及鉛酸蓄電池的端子防鏽方法。The invention relates to a lead-acid battery and a method for preventing rust of a terminal of a lead-acid battery.

習知有：具備有電槽、及露出於電槽外的正極端子及負極端子之鉛酸蓄電池。這類端子，係以鉛合金等之金屬材所形成，且作成按照規格之形狀。例如，搭載於摩托車之鉛酸蓄電池中，將各端子作成箱形端子(例如，參照專利文獻1)。 [先前技術文獻] [專利文獻]It is known that there is a lead-acid battery provided with an electric tank, and a positive terminal and a negative terminal exposed outside the electric tank. This type of terminal is made of metal materials such as lead alloy, and is shaped according to specifications. For example, in a lead-acid battery mounted on a motorcycle, each terminal is made into a box-shaped terminal (for example, refer to Patent Document 1). [Prior Technical Literature] [Patent Literature]

[發明所欲解決之問題][Problems to be solved by the invention]

然而，得知：在將鉛酸蓄電池以相當於熱帶地區之高溫多濕環境予以保管之情況時，恐有在鉛合金製的各端子之表面形成氧化鉛，且端子進行白色化之虞。 為了避開各端子的表面氧化，即便將眾所周知之防鏽劑塗佈於各端子，各端子的表面會進行黑色化，且變成無法維持金屬光澤之狀態。其理由是因眾所周知之防鏽劑含有之礦物油和止鏽劑等，會與端子進行化學反應。However, it was found that when the lead-acid battery is stored in a high-temperature and high-humidity environment equivalent to a tropical region, there is a possibility that lead oxide is formed on the surface of each terminal made of lead alloy and the terminal may become white. In order to avoid surface oxidation of each terminal, even if a well-known rust inhibitor is applied to each terminal, the surface of each terminal will be blackened and the state of metallic luster cannot be maintained. The reason is that the mineral oil and rust inhibitor contained in the well-known rust inhibitor will react chemically with the terminal.

因此，本發明之目的，係使即便在高溫多濕環境亦可防止各端子之氧化，且亦可防止因使用於防鏽的材料與各端子之化學反應所造成的變色。 此外，雖被提案有：於銅製或銅合金製之芯金的表面之至少一部分塗佈焊劑(有機松香)，且抑制芯金與構成極柱本體之主體的鉛合金之緊貼性的降低而具備電阻較低的極柱構造之鉛酸蓄電池(參照日本特許第4876323號公報)，但與本發明其目的、結構、效果完全不同。亦即，本發明並非僅是轉用眾所周知之技術，而是根據新穎之見解所研創。 [用以解決問題之手段]Therefore, the object of the present invention is to prevent oxidation of each terminal even in a high-temperature and humid environment, and to prevent discoloration caused by a chemical reaction between a material used for rust prevention and each terminal. In addition, although it has been proposed to apply flux (organic rosin) to at least a part of the surface of the core gold made of copper or copper alloy, and to suppress the decrease in the adhesion between the core gold and the lead alloy constituting the main body of the pole, A lead-acid battery having a pole structure with low resistance (refer to Japanese Patent No. 4876323), but its purpose, structure, and effects are completely different from the present invention. That is to say, the present invention is not just a conversion to a well-known technology, but is developed based on novel insights. [Means to solve the problem]

又，本發明，係具備有電池本體、及露出於電池本體外的正極端子及負極端子之鉛酸蓄電池的端子防鏽方法，其特徵為：使用松香來作為由上述正極端子及上述負極端子所構成之各端子的防鏽劑。In addition, the present invention is a terminal rust prevention method for a lead-acid battery provided with a battery body and a positive terminal and a negative terminal exposed outside the battery body, characterized in that rosin is used as the positive electrode terminal and the negative electrode terminal Anti-corrosive agent for each terminal.

又，在上述結構中，亦可：在上述端子，設置有連接部，該連接部是接合於配置在上述電池本體內的極板，且各端子與上述電池本體係藉由嵌件成型被一體化，並且在將上述連接部接合於上述極板之前，且在上述嵌件成型之前，以松香覆蓋各端子之整體。Furthermore, in the above-mentioned structure, the terminal may be provided with a connecting portion which is joined to a pole plate arranged in the battery body, and each terminal and the battery system are integrated by insert molding Before joining the connection portion to the electrode plate and before insert molding, the entire terminal is covered with rosin.

根據本發明，則即使在高溫多濕環境亦可防止各端子之氧化，且亦可防止因使用於防鏽的材料與各端子之化學反應所造成的變色。According to the present invention, oxidation of each terminal can be prevented even in a high-temperature and humid environment, and discoloration caused by a chemical reaction between a material used for rust prevention and each terminal can also be prevented.

[發明之實施形態][Embodiment of the invention]

以下，說明關於本發明之一實施形態。 第1圖，係本發明之實施形態的鉛酸蓄電池之立體圖。 鉛酸蓄電池1，係具備有：直方體形狀之電池本體2、及露出於電池本體2外之複數個端子3。電池本體2，係具備有：將內部劃分成複數個室，且於各室配置有複數個極板之箱形的電槽2A、及覆蓋電槽2A的上方開口之蓋2B。電槽2A及蓋2B，係以聚丙烯(PP)等之樹脂材所形成。Hereinafter, an embodiment of the present invention will be described. Figure 1 is a perspective view of a lead-acid battery according to an embodiment of the present invention. The lead-acid battery 1 includes a battery body 2 in the shape of a cuboid, and a plurality of terminals 3 exposed outside the battery body 2. The battery body 2 includes a box-shaped electric cell 2A in which the interior is divided into a plurality of chambers, and a plurality of electrode plates are arranged in each cell, and a cover 2B covering the upper opening of the electric cell 2A. The electric tank 2A and the cover 2B are formed of a resin material such as polypropylene (PP).

複數個端子3，係以正極端子與負極端子所構成。本實施形態中，係將正極端子與負極端子以同一配件所形成。但是，在正極端子與負極端子亦可一部分之形狀等不同。 該鉛酸蓄電池1，係為摩托車用之鉛酸蓄電池，且將端子3形成為中空箱形之箱形端子。但是，該鉛酸蓄電池，係亦可非摩托車用，亦可為被使用於各種各樣的用途之電池。又，端子3之形狀係亦可按照規格作適當地變更。The plurality of terminals 3 is composed of a positive terminal and a negative terminal. In this embodiment, the positive electrode terminal and the negative electrode terminal are formed with the same fitting. However, the shape of a part of the positive electrode terminal and the negative electrode terminal may be different. The lead-acid battery 1 is a lead-acid battery for motorcycles, and the terminal 3 is formed as a hollow box-shaped box-shaped terminal. However, this lead-acid battery can be used not only for motorcycles, but also for batteries used in various applications. In addition, the shape of the terminal 3 may be appropriately changed according to the specifications.

第2圖係將端子3與周邊結構一起顯示之圖。 在端子3，一體地設置有接合在複數個同極性的極板之連接部4，也稱之為套管端子。該連接部4，係具有：從端子3延伸之極柱5、及接合在與極柱5中之端子3為相反側之連接片6。端子3、極柱5及連接片6係使用鉛合金等之金屬材料並藉由鑄造一體地形成。 Figure 2 is a diagram showing the terminal 3 together with the surrounding structure. The terminal 3 is integrally provided with a connecting portion 4 which is joined to a plurality of polar plates of the same polarity, and is also called a sleeve terminal. The connecting portion 4 has a pole 5 extending from the terminal 3 and a connecting piece 6 joined to the opposite side of the terminal 3 in the pole 5. The terminal 3, the pole 5, and the connecting piece 6 are integrally formed by casting using a metal material such as lead alloy.

此外，在與極柱5相對應之處，設置有突出於極柱5的周圍之複數個鍔部5A，且於與該等鍔部5A相對應之區域將蓋2B藉由嵌件成型一體化。 In addition, at the place corresponding to the pole 5, a plurality of flange parts 5A protruding around the pole 5 are provided, and the cover 2B is integrated by insert molding in a region corresponding to these flange parts 5A .

然而，根據發明者之研討，得知：於端子3不塗佈防鏽劑之情況時，若將鉛酸蓄電池1以相當於熱帶地方等之高溫多濕環境予以保管時，就會有：端子3之表面氧化，且藉由氧化鉛端子進行白色化之虞。 However, according to the research of the inventor, when the terminal 3 is not coated with the rust inhibitor, if the lead-acid battery 1 is stored in a high-temperature and humid environment equivalent to a tropical place, there will be: The surface of 3 is oxidized and may be whitened by the lead oxide terminal.

為了對應於此，得知：即便將眾所周知之防鏽劑塗佈於端子3，防鏽劑會與端子3的金屬引起化學反應，且端子3會進行黑色化，變成無法維持金屬光澤之狀態。 In order to correspond to this, it is known that even if a well-known rust inhibitor is applied to the terminal 3, the rust inhibitor will cause a chemical reaction with the metal of the terminal 3, and the terminal 3 will blacken and become unable to maintain the metallic luster.

本發明者，係將防止端子3之因氧化造成的白色化、及黑色化之材料專心研討後之結果，找到了藉由用一般作為防鏽劑不被使用的松香覆蓋端子3，來防止端子3之白色化、及黑色化等之事。 The inventors of the present invention have focused on the results of materials that prevent the whitening and blackening of the terminal 3 due to oxidation, and found that the terminal 3 is covered with a rosin that is not commonly used as a rust inhibitor to prevent the terminal 3 things like whitening and blackening.

本實施形態中，係藉由以松香覆蓋包含連接部4的端子3之整體，即使在高溫多濕環境下亦可防止端子3之白色化、及黑色化等。 In this embodiment, by covering the entire terminal 3 including the connection portion 4 with rosin, the whitening and blackening of the terminal 3 can be prevented even in a high-temperature and humid environment.

於此，松香，係只要為以松香酸(解毒酸、棕櫚酸、異馬來酸等)為主要成分之松香系樹脂即可，例如為浮油松香(tall rosin)、脂松香(gum rosin)及木松香(wood rosin)等。此外，松香係亦被稱為colophony(松脂)或colophonium (松脂)。 Here, the rosin may be a rosin-based resin containing rosin acid (detoxic acid, palmitic acid, isomaleic acid, etc.) as a main component, for example, tall rosin and gum rosin And wood rosin (wood rosin) and so on. In addition, the rosin family is also known as colophony (colophony) or colophonium (Rosin).

對於松香之用途，習知有：在將以往的鉛酸蓄電池之端子3與電槽2A之蓋2B嵌件成型之際，作為使端子3與蓋2B之緊貼性提高的焊劑之用途(例如，日本特表2001-504631號公報)，和在將鉛酸蓄電池1之極柱5鑄入於鉛合金之際，作為使該等之緊貼性提高的焊劑之用途(例如，日本特許第4876323號公報)。 For the use of rosin, it is known that when insert molding the terminal 3 of the conventional lead-acid battery and the cover 2B of the cell 2A, it is used as a flux to improve the adhesion between the terminal 3 and the cover 2B (for example , Japanese Special Publication No. 2001-504631), and the use of the flux to improve the adhesion of the lead-acid battery 1 when the pole 5 of the lead-acid battery 1 is cast into the lead alloy (for example, Japanese Patent No. 4876323 Bulletin).

本實施形態中，係在將端子3與電槽2A之蓋2B嵌件成型之前，且在將端子3之連接部4接合於極板之前，藉由先以松香覆蓋端子3之整體，將松香兼用於防鏽劑、及使各部之緊貼性提高的焊劑之雙方。 In this embodiment, before insert molding the terminal 3 and the cover 2B of the electric tank 2A, and before joining the connecting portion 4 of the terminal 3 to the electrode plate, the entire terminal 3 is covered with rosin to It is used for both rust inhibitors and fluxes to improve the adhesion of each part.

第3圖，係顯示從製作端子3到出貨鉛酸蓄電池1之製造製程的一例。 FIG. 3 shows an example of the manufacturing process from manufacturing the terminal 3 to shipping the lead-acid battery 1.

如第3圖所示，首先，作為步驟S1，實施：藉由鑄造來製作端子3之端子製作製程。藉此，將端子3與連接部4一起一體地製作。此外，製作端子之方法，係可廣泛地適用眾所周知之方法。 As shown in FIG. 3, first, as step S1, a terminal manufacturing process for manufacturing the terminal 3 by casting is carried out. With this, the terminal 3 and the connecting portion 4 are integrally fabricated. In addition, the method of making the terminal is widely applicable to well-known methods.

其次，作為步驟S2，實施：將粉末狀之松香與酒精予以混合，並使端子3浸漬於使含有松香的酒精溶液之後，再進行乾燥之松香浸漬及乾燥製程。藉此，即使端子3為具有複雜形狀之箱形端子，亦可輕易地以松香覆蓋端子3整體。此外，對於浸漬及乾燥所需要之時間和溫度條件係只要適當地設定即可。 Next, as step S2, a powdered rosin and alcohol are mixed, and the terminal 3 is immersed in an alcohol solution containing rosin, and then a dry rosin dipping and drying process is performed. Thereby, even if the terminal 3 is a box-shaped terminal having a complicated shape, the entire terminal 3 can be easily covered with rosin. In addition, the time and temperature conditions required for immersion and drying may be appropriately set.

又，將上述松香與上述酒精混合後之酒精溶液的濃度，係1％～5％較為理想。上述濃度未滿1％之情況時，防止端子的氧化之效果很低。又，超過5％之情況時，由於效果會呈飽和狀態，因此若也考慮成本之面時，5％以下較為理想。In addition, the concentration of the alcohol solution obtained by mixing the rosin and the alcohol is preferably 1% to 5%. When the above concentration is less than 1%, the effect of preventing oxidation of the terminal is very low. In addition, when it exceeds 5%, the effect will be saturated, so if the cost aspect is also considered, it is preferably 5% or less.

接著，作為步驟S3，實施：裝配鉛酸蓄電池1之電池裝配製程。該製程，係包含利用鑄焊(Cast On Strap)方式等之眾所周知的方法來將端子3與極板接合之製程、將端子3嵌件成型於電槽2A的蓋2B之製程等之眾所周知的製程，且進行到鉛酸蓄電池1之最終裝配。 之後，作為步驟S4，將鉛酸蓄電池1搬運到包裝．出貨檢查之生產線。藉此，進行鉛酸蓄電池1之包裝、及用以出貨之各種檢查。Next, as step S3, a battery assembly process for assembling the lead-acid battery 1 is implemented. This process includes well-known processes such as the process of joining the terminal 3 and the electrode plate by well-known methods such as the Cast On Strap method, the process of insert-molding the terminal 3 into the cover 2B of the cell 2A, etc. , And proceed to the final assembly of the lead-acid battery 1. Thereafter, as step S4, the lead-acid battery 1 is transported to the packaging. Production line for shipment inspection. With this, the packaging of the lead-acid battery 1 and various inspections for shipment are performed.

如此般地，由於在電池裝配製程之前以松香覆蓋端子3，因此在電池裝配製程中，不需要將松香塗佈於端子3之工作，以松香覆蓋端子3之製程一次即可。又，根據松香浸漬．乾燥製程，可避免對於端子3之松香的遺漏塗佈處。In this way, since the terminal 3 is covered with rosin before the battery assembly process, there is no need to apply rosin to the terminal 3 during the battery assembly process, and the process of covering the terminal 3 with rosin can be performed only once. Also, impregnated under rosin. The drying process can avoid the missing coating of the rosin of the terminal 3.

將如上述般地製造之鉛酸蓄電池1作為實施例1，與比較例1、2進行比較。 比較例1，係為於端子3沒有塗佈松香及防鏽劑之鉛酸蓄電池，而比較例2，係為於端子3塗佈了眾所周知的防鏽劑之鉛酸蓄電池。使用於比較例2之防鏽劑，係由礦物油、止鏽劑、及石油系溶劑所構成。The lead-acid battery 1 manufactured as described above was used as Example 1 and compared with Comparative Examples 1 and 2. Comparative Example 1 is a lead-acid battery in which terminal 3 is not coated with rosin and rust inhibitor, and Comparative Example 2 is a lead-acid battery in which terminal 3 is coated with a well-known rust inhibitor. The rust inhibitor used in Comparative Example 2 is composed of mineral oil, rust inhibitor, and petroleum-based solvent.

在將實施例1、及比較例1、2之各鉛酸蓄電池分別包裝於紙製的箱子之狀態於80度之溫度環境各保管7天、12天、21天。接著，進行下述之實驗：將各鉛酸蓄電池於–10℃之溫度環境保管一天之後，打開箱子某既定時間，使箱子潮溼(使之成潮溼之狀態)，之後，在關閉箱子之狀態下以保鮮膜覆蓋箱子整體，並觀察在常溫環境經過一星期之後的端子3。將該實驗結果顯示於表1。The lead-acid batteries of Example 1 and Comparative Examples 1 and 2 were respectively stored in a paper box in a temperature environment of 80 degrees for 7 days, 12 days, and 21 days, respectively. Next, perform the following experiment: after storing each lead-acid battery in a temperature environment of –10°C for one day, open the box for a predetermined time to make the box wet (make it wet), and then, with the box closed Cover the whole box with plastic wrap and observe the terminal 3 after one week in normal temperature. Table 1 shows the results of this experiment.

Figure 02_image001
◎：沒有白色化且可維持金屬光澤 ○：沒有白色化 △：些許白色化 ×：強烈白色化
Figure 02_image001
◎: No whitening and maintain metallic luster ○: No whitening △: Slight whitening ×: Strong whitening

如表1所示，比較例1之鉛酸蓄電池1，係不管是哪個條件端子3之表面整體都白色化，已進行氧化。比較例2，係各保管21天的條件之端子3會部分白色化。又，比較例2，係不管哪個條件都無法維持端子3之金屬光澤，而變成暗淡之狀態。 相對於此，實施例1中，係不管哪個條件都不會出現端子3之白色化，且亦可維持端子3之金屬光澤。該效果，係有松香之作為界面活性劑的作用貢獻之可能性。As shown in Table 1, the lead-acid battery 1 of Comparative Example 1 is whitened and oxidized regardless of the conditions. In Comparative Example 2, the terminal 3 which was stored for 21 days was partially whitened. In addition, in Comparative Example 2, the metallic luster of the terminal 3 could not be maintained regardless of the conditions, and it became a dull state. In contrast, in Example 1, no whitening of the terminal 3 occurs regardless of the conditions, and the metallic luster of the terminal 3 can also be maintained. This effect is likely to contribute to the role of rosin as a surfactant.

又，發明者等，係確認了：在對於將鉛酸蓄電池1的端子3之表面予以研磨，並以松香覆蓋該端子3者也進行同樣的實驗之情況時，也不會出現端子3之白色化，且亦可維持端子3之金屬光澤。亦即，藉由進行研磨，即使為更易於加深白色化和暗淡之狀態，而藉由以松香覆蓋，亦可充分地抑制白色化和暗淡。 In addition, the inventors confirmed that when the surface of the terminal 3 of the lead-acid battery 1 was polished and the terminal 3 was covered with rosin and the same experiment was conducted, the whiteness of the terminal 3 did not appear. It can also maintain the metallic luster of the terminal 3. That is, by grinding, even if it is easier to deepen the whitening and dullness, and by covering with rosin, the whitening and dullness can be sufficiently suppressed.

如以上說明，由於以松香覆蓋由正極端子及負極端子所構成之各端子3來進行防鏽化，因此即使在高溫多濕環境亦可防止各端子之氧化，且亦可防止因使用於防鏽的材料與各端子之化學反應所造成的變色。 As described above, since the terminals 3 composed of the positive terminal and the negative terminal are covered with rosin for rust prevention, the oxidation of each terminal can be prevented even in a high-temperature and humid environment, and can also be prevented from being used for rust prevention. Discoloration caused by the chemical reaction between the material and the terminals.

換言之，藉由找到對於松香作為防鏽劑之用途，可提供對於鉛酸蓄電池1之端子3適合的防鏽方法。 In other words, by finding the use of rosin as a rust inhibitor, a suitable rust prevention method for the terminal 3 of the lead-acid battery 1 can be provided.

又，由於以松香覆蓋包含被接合於極板之連接部4的端子3之整體，因此藉由在電池裝配製程之前以松香覆蓋端子3，在電池裝配製程中，不僅不需要將松香塗佈於端子3之工作，還可將松香兼用作為防鏽劑、及使各部之緊貼性提高的焊劑之雙方。 Furthermore, since the entire terminal 3 including the connection portion 4 joined to the electrode plate is covered with rosin, by covering the terminal 3 with rosin before the battery assembly process, it is not necessary to apply rosin to the battery assembly process For the operation of the terminal 3, the rosin can also be used as both a rust inhibitor and a flux that improves the adhesion of each part.

又，由於端子3，係露出於電池本體2外之部分為中空箱形之箱形端子，因此藉由採用將箱形端子浸漬於含有松香之液體，且進行乾燥之簡易的製程，可輕易地以松香覆蓋箱形端子。 In addition, since the terminal 3 is a hollow box-shaped box terminal exposed outside the battery body 2, the simple process of dipping the box-shaped terminal in a liquid containing rosin and drying it can easily Cover the box terminals with rosin.

此外，上述之實施形態，係到底僅是顯示本發明之一態樣者，在不脫離本發明的主旨之範圍內是可任意地變形及應用。例如，雖說明了將本發明適用於第1圖 所示之鉛酸蓄電池1、及鉛酸蓄電池1的端子防鏽方法之情況，但並不限定於此，亦可適用於眾所周知之其他的鉛酸蓄電池、及鉛酸蓄電池的端子防鏽方法。 In addition, the above-mentioned embodiment is merely an embodiment of the present invention, and can be arbitrarily modified and applied without departing from the gist of the present invention. For example, although it is described that the present invention is applied to FIG. 1 The case of the lead-acid battery 1 and the terminal-rust-proof method of the lead-acid battery 1 shown is not limited to this, and can be applied to other well-known lead-acid batteries and the terminal-rust-proof method of the lead-acid battery.

又，關於以松香覆蓋各端子之方法，也不限定於上述之方法。例如，亦可為將噴霧狀之松香噴至各端子3之方法等。 Also, the method of covering each terminal with rosin is not limited to the method described above. For example, a method of spraying spray-like rosin to each terminal 3 may be used.
