Description
本発明は、臭気が低減された硬質金属箔の製造方法に関する。 The present invention relates to a method for producing a hard metal foil with reduced odor.
従来から、アルミニウム箔を容器状にプレス成形してなる食品用容器が多数、提供されている。このような食品用容器は、例えば、特許文献１に示したように、アルミニウム箔を複数枚、重ね合わせて積層シートを形成し、この積層シートからブランクを打ち抜き、このブランクを容器形状にプレス成形することによって製造されている。一方、アルミニウム箔は、その製造工程において、圧延箔の表面に圧延油を塗布し、圧延箔と圧延ロールとの間の摩擦を低減させている。 Conventionally, many food containers formed by pressing aluminum foil into containers have been provided. For example, as shown in Patent Document 1, such a food container is formed by laminating a plurality of aluminum foils to form a laminated sheet, punching a blank from the laminated sheet, and pressing the blank into a container shape. It is manufactured by On the other hand, in the production process of aluminum foil, rolling oil is applied to the surface of the rolled foil to reduce friction between the rolled foil and the rolling roll.
しかしながら、上述のように、アルミニウム箔の製造工程において圧延油を使用していることから、得られるアルミニウム箔の表面には圧延油が僅かながら残存しており、このようなアルミニウム箔を食品用容器に用いると、臭気に敏感な者は、圧延油の臭気が気になることがあるといった問題点があった。 However, as described above, since the rolling oil is used in the production process of the aluminum foil, a small amount of the rolling oil remains on the surface of the obtained aluminum foil. When used for, there is a problem that those who are sensitive to odor may be worried about the odor of rolling oil.
本発明は、臭気が低減されており、食品用容器の原材料として好適に用いることができる硬質金属箔の製造方法を提供する。 The present invention provides a method for producing a hard metal foil that has reduced odor and can be suitably used as a raw material for food containers.
本発明の臭気が低減された硬質金属箔の製造方法は、表面に圧延油が残存している長尺状の硬質金属箔の少なくとも一面に、脂肪酸グリセリドを溶媒に溶解させてなり且つ脂肪酸グリセリドを０．０１〜１．０重量％含有する洗浄溶液を１〜１０ｇ／ｍ2 となるように塗布した後、硬質金属箔を加熱して上記溶媒を蒸発、除去した上で巻取り軸に連続的に巻き取ることを特徴とする。 The method for producing a hard metal foil with reduced odor according to the present invention comprises dissolving a fatty acid glyceride in a solvent on at least one surface of a long hard metal foil having rolling oil remaining on the surface, and After applying a cleaning solution containing 0.01 to 1.0% by weight to 1 to 10 g / m 2 , the hard metal foil is heated to evaporate and remove the solvent, and then continuously on the winding shaft. It is characterized in that it is wound up.
先ず、本発明で用いられる長尺状の硬質金属箔は、汎用の方法を用いて製造されたものが用いられるが、ＪＩＳ Ｈ０００１に規定されているように「最終焼なましのないもの」であり、具体的には、鋳塊に含有される元素成分の偏析を極力小さくするために鋳塊を均一に加熱する均質化処理を行い、この均質化処理が施された鋳塊に熱間圧延処理及び冷間圧延処理を順次、施して、長尺状の金属箔とされたものであり、上記圧延処理にあたって、鋳塊に圧延処理を施して得られる圧延箔の表面には、この圧延箔と圧延ロールとの間の摩擦抵抗を低減させる目的で圧延油が供給される。なお、冷間圧延の途中で中間焼鈍を施してもよい。 First, the long hard metal foil used in the present invention is manufactured by using a general-purpose method. However, as defined in JIS H0001, it is “without final annealing”. Yes, specifically, in order to minimize the segregation of elemental components contained in the ingot, the ingot is uniformly heated, and the ingot subjected to the homogenization treatment is hot-rolled. In this rolling process, the surface of the rolled foil obtained by rolling the ingot is subjected to the rolling foil. Rolling oil is supplied for the purpose of reducing the frictional resistance between the steel and the rolling roll. In addition, you may give an intermediate annealing in the middle of cold rolling.
上記金属箔としては、特に限定されず、例えば、アルミニウム箔、ステンレス箔、銅箔などが挙げられ、アルミニウム箔が好ましく、Ａｌ純度が９５重量％以上であるアルミニウム箔がより好ましい。 The metal foil is not particularly limited, and examples thereof include an aluminum foil, a stainless steel foil, and a copper foil. An aluminum foil is preferable, and an aluminum foil having an Al purity of 95% by weight or more is more preferable.
上記圧延油は、圧延処理中に圧延箔に加えられる熱によって蒸発、除去されるものの、完全に除去されるものではなく、得られる硬質金属箔の表面には僅かながら圧延油が残存している。 Although the rolling oil is evaporated and removed by heat applied to the rolled foil during the rolling process, it is not completely removed, and the rolling oil remains slightly on the surface of the obtained hard metal foil. .
そして、本発明では、上述の硬質金属箔の表面に残存した圧延油を除去或いは包み込んで圧延油に起因した臭気を除去するために、硬質金属箔の少なくとも一面に、好ましくは両面に、脂肪酸グリセリドを溶媒に溶解させてなる洗浄溶液を塗布する。 In the present invention, in order to remove or wrap the rolling oil remaining on the surface of the hard metal foil and remove the odor caused by the rolling oil, fatty acid glycerides are provided on at least one surface, preferably both surfaces of the hard metal foil. A cleaning solution prepared by dissolving in a solvent is applied.
なお、硬質金属箔の少なくとも一面に洗浄溶液を塗布する方法としては、汎用の方法が用いられ、例えば、オフセットグラビアコーター、グラビアリバースコーター、コンマコーターなどのグラビアコーター、キスロールコーター、ボトムリバースコーター、バーコーター、スプレーコーターなどを用いて塗布する方法が挙げられる。 In addition, as a method of applying the cleaning solution to at least one surface of the hard metal foil, a general-purpose method is used, for example, gravure coater such as offset gravure coater, gravure reverse coater, comma coater, kiss roll coater, bottom reverse coater, The method of apply | coating using a bar coater, a spray coater, etc. is mentioned.
上記脂肪酸グリセリドとしては、脂肪酸モノグリセリド、脂肪酸ジグリセリド、脂肪酸モノグリセリドの何れであってもよいが、脂肪酸トリグリセリドが好ましく、式１で示される脂肪酸グリセリドがより好ましい。 The fatty acid glyceride may be any of a fatty acid monoglyceride, a fatty acid diglyceride, and a fatty acid monoglyceride, but is preferably a fatty acid triglyceride, and more preferably a fatty acid glyceride represented by Formula 1.
そして、式１で示される構造式を有する脂肪酸トリグリセリドのＲ1 ，Ｒ2 ，Ｒ3 は、ヘプチル基又はノニル基であることから、式１で示される脂肪酸トリグリセリドは、Ｒ1 ，Ｒ2 ，Ｒ3 におけるヘプチル基とノニル基との組合せによって、複数種類の構造式を持った脂肪酸トリグリセリドの混合物となっている。 Since R 1 , R 2 , and R 3 of the fatty acid triglyceride having the structural formula represented by Formula 1 are heptyl groups or nonyl groups, the fatty acid triglyceride represented by Formula 1 is R 1 , R 2 , R The combination of heptyl group and nonyl group in 3 is a mixture of fatty acid triglycerides having a plurality of structural formulas.
更に、式１で示される構造式を有する脂肪酸トリグリセリドのＲ1 〜Ｒ3 の総量中、８０〜９０モル％がヘプチル基で且つ１０〜２０モル％がノニル基であることが好ましい。これは、ヘプチル基又はノニル基のモル％が上記範囲外となると、硬質金属箔の臭気の低減効果が低下する虞れがあるからである。 Furthermore, the total amount of R 1 to R 3 fatty acid triglyceride having the structure of formula 1, is preferably 80 to 90 mol% and 10 to 20 mole percent heptyl nonyl group. This is because if the mol% of heptyl group or nonyl group is outside the above range, the effect of reducing the odor of the hard metal foil may be lowered.
洗浄溶液中における脂肪酸グリセリドの含有量は、少ないと、圧延油に起因した臭気の除去効果が発現しない一方、多いと、巻き取られた硬質金属箔を巻き出す際に内外方向に隣接する硬質金属箔同士が密着してしまい互いに剥離しにくくなるので、０．０１〜１．０重量％に限定される。 If the content of the fatty acid glyceride in the cleaning solution is small, the effect of removing odor caused by the rolling oil is not expressed. On the other hand, if the content is large, the hard metal adjacent to the inside and outside when unwinding the wound hard metal foil. Since the foils are in close contact with each other and are difficult to peel from each other, the content is limited to 0.01 to 1.0% by weight.
そして、脂肪酸グリセリドを溶解させる溶媒としては、脂肪酸グリセリドを溶解させることができれば、特に限定されないが、圧延油或いは圧延油の一部を溶解させることができ、硬質金属箔の表面に洗浄溶液を塗布した後の加熱によって圧延油の蒸発を助長できる点で、酢酸エチル、アセトン、トルエン、メチルエチルケトン、メチルイソブチルケトン、ノルマルパラフィン、メタノール、エタノール、イソプロパノール及びブタノールからなる群から選ばれた一種又は二種以上の溶媒が好ましい。なお、溶媒は、単独で用いられても二種以上が併用されてもよい。 The solvent for dissolving the fatty acid glyceride is not particularly limited as long as the fatty acid glyceride can be dissolved, but the rolling oil or a part of the rolling oil can be dissolved, and the cleaning solution is applied to the surface of the hard metal foil. One or more selected from the group consisting of ethyl acetate, acetone, toluene, methyl ethyl ketone, methyl isobutyl ketone, normal paraffin, methanol, ethanol, isopropanol, and butanol, in that the evaporation of the rolling oil can be facilitated by heating after These solvents are preferred. In addition, a solvent may be used independently or 2 or more types may be used together.
なお、上記洗浄溶液中には、オリーブ油、コーン油、ごま油、大豆油、なたね油、パーム油、ひまわり油、落花生油などを添加してもよい。 Note that olive oil, corn oil, sesame oil, soybean oil, rapeseed oil, palm oil, sunflower oil, peanut oil, and the like may be added to the cleaning solution.
又、硬質金属箔の少なくとも一面に塗布する洗浄溶液の量は、少ないと、硬質金属箔に残存する圧延油の除去が不充分となり、得られる硬質金属箔の臭気が低減されない虞れがある一方、多いと、硬質金属箔の表面の脂肪酸グリセリドが多くなり、巻取り軸に巻き取った硬質金属箔同士がひっついて互いに剥離し難くなるので、１〜１０ｇ／ｍ2 に限定される。 On the other hand, if the amount of the cleaning solution applied to at least one surface of the hard metal foil is small, the rolling oil remaining on the hard metal foil may not be sufficiently removed, and the odor of the obtained hard metal foil may not be reduced. If the amount is too large, the amount of fatty acid glycerides on the surface of the hard metal foil increases, and the hard metal foils wound on the winding shaft stick together, making it difficult to peel off from each other, so it is limited to 1 to 10 g / m 2 .
又、硬質金属箔の少なくとも一面に洗浄溶液を塗布する前に、硬質金属箔の表面に残存する圧延油を下記に示す低減化前処理を施すことによって低減させておくことが好ましい。このような低減化前処理としては、例えば、（１）硬質金属箔の表面をブラシで擦る方法、（２）硬質金属箔の表面に加圧空気を噴射し、この加圧空気によって硬質金属箔表面の圧延油を吹き飛ばす方法、（３）硬質金属箔の表面の圧延油を吸引除去するする方法、（４）圧延油を溶解し得る溶剤を硬質金属箔の表面に塗布し、圧延油を溶解させた溶剤を除去することによって、硬質金属箔の表面の圧延油を除去する方法が好ましい。なお、上記（４）の方法で用いられる溶剤としては、洗浄溶液の溶媒と同様のものが用いられるのでその説明を省略する。 In addition, before applying the cleaning solution to at least one surface of the hard metal foil, it is preferable to reduce the rolling oil remaining on the surface of the hard metal foil by performing the pre-reduction treatment described below. As such pre-reduction treatment, for example, (1) a method of rubbing the surface of the hard metal foil with a brush, (2) pressurized air is jetted onto the surface of the hard metal foil, and the hard metal foil is sprayed by this pressurized air. The method of blowing off the rolling oil on the surface, (3) The method of sucking and removing the rolling oil on the surface of the hard metal foil, (4) The solvent that can dissolve the rolling oil is applied to the surface of the hard metal foil, and the rolling oil is dissolved A method of removing the rolling oil on the surface of the hard metal foil by removing the formed solvent is preferable. The solvent used in the above method (4) is the same as the solvent used in the cleaning solution, and the description thereof is omitted.
次に、硬質金属箔の少なくとも一面に洗浄溶液を塗布した後に硬質金属箔を加熱し、洗浄溶液の溶媒を蒸発、除去する。この溶媒の蒸発に伴って、硬質金属箔の表面に残存した圧延油の蒸発も助長することができ、得られる硬質金属箔の表面に残存する圧延油量を低減して硬質金属箔の臭気を低減することができる。 Next, after applying the cleaning solution to at least one surface of the hard metal foil, the hard metal foil is heated to evaporate and remove the solvent of the cleaning solution. Along with the evaporation of the solvent, the evaporation of the rolling oil remaining on the surface of the hard metal foil can be promoted, and the amount of the rolling oil remaining on the surface of the obtained hard metal foil is reduced to reduce the odor of the hard metal foil. Can be reduced.
そして、洗浄溶液の溶媒が蒸発した後の硬質金属箔の一面には脂肪酸グリセリドが均一に全面的に塗布された状態となっており、この脂肪酸グリセリドが、硬質金属箔の表面に残存した圧延油を包み込み、圧延油に起因する臭気を抑制することができる。 Then, the fatty acid glyceride is uniformly and entirely applied to one surface of the hard metal foil after the solvent of the cleaning solution has evaporated, and the fatty acid glyceride is the rolling oil remaining on the surface of the hard metal foil. The odor resulting from the rolling oil can be suppressed.
上記硬質金属箔の加熱温度は、低いと、溶媒が充分に蒸発せず、硬質金属箔表面に残存し、得られる硬質金属箔に溶媒に起因する臭気が発生することがある一方、高いと、硬質金属箔が軟化して硬質金属箔に皺が生じたり或いは亀裂が発生する虞れがあるので、８０〜２００℃が好ましい。 When the heating temperature of the hard metal foil is low, the solvent does not sufficiently evaporate and remains on the surface of the hard metal foil, and the resulting hard metal foil may generate an odor due to the solvent, whereas if high, Since there is a possibility that the hard metal foil softens and the hard metal foil is wrinkled or cracked, 80 to 200 ° C. is preferable.
しかる後、硬質金属箔を巻取り軸に連続的に巻取った上で所定期間に亘って放置する。すると、硬質金属箔の少なくとも一面には脂肪酸グリセリドが全面的に塗布された状態となっていると共に、硬質金属箔同士が内外方向に互いに密着した状態となっているので、内外方向に互いに密着した硬質金属箔間において、一方の硬質金属箔の一面に塗布された脂肪酸グリセリドの一部が、他方の硬質金属箔の他面に転写され、双方の硬質金属箔の両面に脂肪酸グリセリドが全面的に塗布された状態となる。 Thereafter, the hard metal foil is continuously wound around the winding shaft and then left for a predetermined period. Then, at least one surface of the hard metal foil is in a state where the fatty acid glyceride is entirely applied, and since the hard metal foils are in close contact with each other in the inner and outer directions, they are in close contact with each other in the inner and outer directions. Between the hard metal foils, a part of the fatty acid glycerides applied to one surface of one hard metal foil is transferred to the other surface of the other hard metal foil, and the fatty acid glycerides are entirely formed on both surfaces of both hard metal foils. It will be in the applied state.
なお、硬質金属箔の両面に洗浄溶液を塗布した場合には、硬質金属箔の両面に既に脂肪酸グリセリドが全面的に塗布された状態となっているが、上述のように、硬質金属箔同士を互いに密着させることによって、硬質金属箔の両面に脂肪酸グリセリン量を全面的に均等に塗布することができる。 In addition, when the cleaning solution is applied to both surfaces of the hard metal foil, the fatty acid glyceride is already applied to both surfaces of the hard metal foil. By bringing them into close contact with each other, the amount of fatty acid glycerin can be uniformly applied to both surfaces of the hard metal foil.
このように、硬質金属箔の両面に塗布された脂肪酸グリセリドは、硬質金属箔の両面に僅かに残存した圧延油を包み込み、圧延油に起因した臭気が硬質金属箔から発生するのを概ね防止して、臭気の低減された硬質金属箔を得ることができる。 In this way, the fatty acid glycerides applied on both sides of the hard metal foil wraps the rolling oil slightly remaining on both sides of the hard metal foil, and generally prevents the odor caused by the rolling oil from being generated from the hard metal foil. Thus, a hard metal foil with reduced odor can be obtained.
次に、臭気の低減された硬質金属箔を用いて食品用容器を製造する要領について説明する。先ず、臭気の低減された硬質金属箔を所定長さ毎に切断して、複数枚の硬質金属箔シートを作製する。次に、この硬質金属箔シートを複数枚、重ね合わせて積層シートとし、この積層シートから平面円形状のブランクを打ち抜く。 Next, the point which manufactures the container for foodstuffs using the hard metal foil with which the odor was reduced is demonstrated. First, a hard metal foil with reduced odor is cut into predetermined lengths to produce a plurality of hard metal foil sheets. Next, a plurality of the hard metal foil sheets are overlapped to form a laminated sheet, and a planar circular blank is punched from the laminated sheet.
そして、上記ブランクを容器状にプレス成形することによって、複数個の食品用容器が重なり合った積層体を得ることができる。この積層体の食品用容器を使用するには、最上層にある食品用容器をこの食品用容器に隣接する食品用容器から剥離させる必要がある。 And the laminated body in which the container for several foods overlapped can be obtained by press-molding the said blank in a container shape. In order to use the food container of this laminate, it is necessary to peel the food container in the uppermost layer from the food container adjacent to the food container.
この際、食品用容器の両面には脂肪酸グリセリドが全面的に塗布された状態となっていることから、隣接する食品用容器同士を剥離する際の抵抗が低減されており、食品用容器を一個づつ円滑に剥離して使用することができる。 At this time, since the fatty acid glyceride is completely applied to both surfaces of the food container, the resistance when peeling adjacent food containers is reduced, and one food container is provided. It can be smoothly peeled off one by one.
本発明の硬質金属箔の製造方法は、表面に圧延油が残存している長尺状の硬質金属箔の少なくとも一面に、脂肪酸グリセリドを溶媒に溶解させてなり且つ脂肪酸グリセリドを０．０１〜１．０重量％含有する洗浄溶液を１〜１０ｇ／ｍ2 となるように塗布した後、硬質金属箔を加熱して上記溶媒を蒸発、除去した上で巻取り軸に連続的に巻き取ることを特徴とするので、洗浄溶液の溶媒の蒸発に伴って圧延油の蒸発、除去を助長し、硬質金属箔上に残存した圧延油の量を低減し、更に、硬質金属箔上に依然として残存した僅かな量の圧延油を脂肪酸グリセリドによって包み込んでおり、得られる硬質金属箔は、圧延油に起因した臭気を殆ど有することはなく、食品用途などにも好適に用いることができる。 In the method for producing a hard metal foil of the present invention, a fatty acid glyceride is dissolved in a solvent on at least one surface of a long hard metal foil whose rolling oil remains on the surface, and the fatty acid glyceride is 0.01 to 1 After applying a cleaning solution containing 0.0 wt% to 1 to 10 g / m 2 , the hard metal foil is heated to evaporate and remove the solvent, and then continuously wound around the winding shaft. As a feature, it facilitates evaporation and removal of the rolling oil as the solvent of the cleaning solution evaporates, reduces the amount of rolling oil remaining on the hard metal foil, and further reduces the amount of remaining rolling oil on the hard metal foil. A large amount of rolled oil is encapsulated with fatty acid glycerides, and the resulting hard metal foil has almost no odor due to the rolled oil and can be suitably used for food applications.
そして、硬質金属箔の表面には脂肪酸グリセリドが塗布されており、従って、硬質金属箔を複数枚、重ね合わせた上で所望形状のブランクに打ち抜き、このブランクを例えば、食品用容器などの所定形状にプレス成形して、複数個の成形品を硬質金属箔の厚み方向に積層した状態に同時に成形した場合にあっても、成形品を一枚づつ簡単に分離させることができる。 The surface of the hard metal foil is coated with fatty acid glycerides. Therefore, a plurality of hard metal foils are stacked and punched into a blank having a desired shape, and the blank is formed into a predetermined shape such as a food container. Even when a plurality of molded products are simultaneously molded in the state of being laminated in the thickness direction of the hard metal foil, the molded products can be easily separated one by one.
又、上記硬質金属箔の製造方法において、脂肪酸グリセリドが上記式１で示される場合には、脂肪酸グリセリドによって圧延油を更に確実に包み込んで圧延油に起因した臭気を更に確実に低減することができる。 Moreover, in the manufacturing method of the said hard metal foil, when fatty acid glyceride is shown by the said Formula 1, rolling oil is more reliably wrapped with fatty acid glyceride, and the odor resulting from rolling oil can be reduced more reliably. .
更に、上記硬質金属箔の製造方法において、式１に示した脂肪酸グリセリドにおけるＲ1 〜Ｒ3 の総量中、８０〜９０モル％がヘプチル基であり、１０〜２０モル％がノニル基である場合には、洗浄溶液の溶媒を蒸発、除去させた後に、硬質金属箔の表面に脂肪酸グリセリドを略均一に塗布した状態とすることができ、硬質金属箔の表面に残存した圧延油を包み込み、圧延油に起因した臭気をより確実に低減することができる。 Furthermore, in the manufacturing method of the said hard metal foil, in the total amount of R < 1 > -R < 3 > in the fatty acid glyceride shown in Formula 1, 80-90 mol% is a heptyl group, and 10-20 mol% is a nonyl group After the solvent of the cleaning solution is evaporated and removed, fatty acid glycerides can be applied almost uniformly on the surface of the hard metal foil, and the rolling oil remaining on the surface of the hard metal foil is wrapped and rolled. Odor due to oil can be reduced more reliably.
