Description
本発明は、金属容器用密封材組成物及びこの金属容器用密封材組成物を塗布して成る金属容器用蓋に関するもので、より詳細には、金属容器蓋等に使用された場合に優れた密封性及び巻締性を有する密封材を形成し得る金属容器用密封材組成物、密封性及び巻締性に優れた金属容器用蓋に関する。 The present invention relates to a metal container sealing material composition and a metal container lid formed by applying the metal container sealing material composition, and more particularly, when used for a metal container lid or the like. The present invention relates to a metal container sealing material composition capable of forming a sealing material having sealing properties and winding properties, and a metal container lid excellent in sealing properties and winding properties.
モーターオイル、工業用潤滑剤または化成品等の内容物を収容する金属容器あるいはエアゾール缶に用いられる密封材組成物としては、耐油性のあるクロロプレンゴムやアクリトロニトリルブタジエンエラストマーが一般に使用されている。
しかしながら、クロロプレンゴムは塩素を含有するものであるため、錆の発生や焼却時のダイオキシン等の発生の問題があり、またアクリロニトリルブタジエンエラストマー（以下、単にＮＢＲということがある）は、形成される膜質が硬いため、容器端用密封材に用いる場合には、巻締性に劣るという問題を有している。このためアクリロニトリルブタジエンエラストマーにおいては、一般に膜質を柔らかくするために軟化剤としてＮＢＲと相溶性のある軟化剤を添加して用いているが、容器端用密封材の巻締性を向上させるためには、軟化剤を多量に使用する必要があった。
Oil-resistant chloroprene rubber or acrylonitrile butadiene elastomer is generally used as a sealing material composition used for metal containers or aerosol cans containing contents such as motor oil, industrial lubricants or chemical products.
However, since chloroprene rubber contains chlorine, there is a problem of generation of rust and dioxins during incineration, and acrylonitrile butadiene elastomer (hereinafter sometimes referred to simply as NBR) is formed film quality. Since it is hard, when it uses for the sealing material for container ends, it has the problem that it is inferior to winding-up property. For this reason, in acrylonitrile butadiene elastomer, in general, a softening agent compatible with NBR is added as a softening agent to soften the film quality, but in order to improve the tightness of the container end sealant It was necessary to use a large amount of softener.
一般に、ＮＢＲに軟化剤を配合した密封材組成物を金属容器蓋等の容器端に使用して金属容器を製造した場合、内容物がトルエン等の良溶媒の場合は、ＮＢＲ自体が膨潤するため、密封材としての密封性が低下することはないが、内容物がモーターオイルやアルコール等の貧溶媒である場合には、ＮＢＲ自体の膨潤性は小さくなるため、全体として密封材がやせ細ってしまい、密封性が低下し、内容物が漏洩する場合があった。 In general, when a metal container is manufactured using a sealing material composition containing NBR and a softener at the end of a container such as a metal container lid, the NBR itself swells when the content is a good solvent such as toluene. The sealing performance as a sealing material does not decrease, but when the content is a poor solvent such as motor oil or alcohol, the swelling property of NBR itself is reduced, and the sealing material is thinned as a whole. In some cases, the sealing performance deteriorated and the contents leaked.
このような問題を解決するものとして、エラストマーに加硫剤、膨潤調整剤その他の添加剤を分散したゴム組成物において、上記の膨潤調整剤として炭酸カルシウム及びクレーの少なくとも一方が加えられ、上記エラストマーの配合量がエラストマーおよび添加剤の合計重量に対して１０〜６０％、上記膨潤調整剤の配合量が上記合計重量に対して５〜１５％であることを特徴とするシール用ゴム組成物及び前記組成物を溶媒に溶解して、塗布等することを特徴とするシール材の製造方法が提案されている（特許文献１）。
上記シール用ゴム組成物は膨潤調整剤として配合された炭酸カルシウム及びクレーがアルコール等の貧溶媒や軟化剤等を吸着固定させてエラストマーの重量低下を補い、シール性を保持するというものであるが、充填剤による膨張調整では密封性及び巻締性の点で未だ十分満足し得るものではない。またかかるシール用ゴム組成物は、溶剤に溶解して使用するものであり、溶剤の揮散による環境への影響や取り扱い性の点から水性分散タイプのものが望まれている。 In the rubber composition for sealing, calcium carbonate and clay blended as a swelling regulator adsorbs and fixes a poor solvent such as alcohol or a softening agent to compensate for a decrease in the weight of the elastomer and maintain a sealing property. However, the expansion adjustment using a filler is not yet satisfactory in terms of sealing performance and winding performance. Such a sealing rubber composition is used after being dissolved in a solvent, and an aqueous dispersion type is desired from the viewpoints of environmental influences and handling properties due to volatilization of the solvent.
従って本発明の目的は、アクリロニトリルブタジエンエラストマーを含有する密封材組成物において、良溶媒に膨潤しすぎず、一方貧溶媒にやせ細ることもなく、密封性、耐久性、巻締性に顕著に優れた密封材を形成可能な金属容器用密封材組成物を提供することである。
本発明の他の目的は、密封性、耐久性、巻締性に優れた密封材を有する金属容器用蓋を提供することである。
Accordingly, an object of the present invention is to provide a sealing material composition containing an acrylonitrile butadiene elastomer, which does not swell excessively in a good solvent, and does not fade into a poor solvent, and is remarkably excellent in sealing properties, durability, and winding properties. It is providing the sealing material composition for metal containers which can form a sealing material.
Another object of the present invention is to provide a lid for a metal container having a sealing material excellent in sealing performance, durability, and winding performance.
本発明によれば、エラストマーを主成分とする金属容器用密封材組成物において、前記エラストマーがアクリロニトリルブタジエンエラストマー及びスチレンブタジエンエラストマーを含有すると共に水性分散液であることを特徴とする金属容器用密封材組成物が提供される。
本発明の金属容器用密封材組成物においては、
１．アクリロニトリルブタジエンエラストマーが、全エラストマー量１００重量部に対し５５乃至９５重量部の量で配合されていること
２．アクリロニトリルブタジエンエラストマーのアクリロニトリル含有量が２５乃至４５重量％であり、トルエン不溶分が４０乃至９０重量％であり、スチレンブタジエンエラストマーのスチレン含有量が１５乃至６５重量％であり、トルエン不溶分が１０乃至８０重量％であること。
３．充填剤、軟化剤、分散剤、老化防止剤及び粘稠剤を含有すること、
が好ましい。
本発明によればまた、上記金属容器用密封材組成物を塗布して成る金属容器用蓋が提供される。
According to the present invention, there is provided a metal container sealing material comprising an elastomer as a main component, wherein the elastomer contains an acrylonitrile butadiene elastomer and a styrene butadiene elastomer and is an aqueous dispersion. A composition is provided.
In the metal container sealing material composition of the present invention,
1. 1. The acrylonitrile butadiene elastomer is blended in an amount of 55 to 95 parts by weight with respect to 100 parts by weight of the total elastomer. The acrylonitrile butadiene elastomer has an acrylonitrile content of 25 to 45% by weight, a toluene insoluble content of 40 to 90% by weight, the styrene butadiene elastomer has a styrene content of 15 to 65% by weight, and a toluene insoluble content of 10 to 10%. 80% by weight.
3. Containing fillers, softeners, dispersants, anti-aging agents and thickeners,
Is preferred.
According to the present invention, there is also provided a metal container lid formed by applying the metal container sealing material composition.
本発明においては、エラストマーから成る金属容器用密封材組成物として、エラストマー成分としてアクリロニトリルブタジエンエラストマー及びスチレンブタジエンエラストマーの組み合わせを採用することにより、トルエン等の良溶媒のみならず、アルコール類やモーターオイル等の貧溶媒を内容物とする金属容器蓋に使用した場合にも、長期に亘って密封材の重量（体積）低下がなく、密封性及び耐久性に優れた密封材を形成することが可能となる。また本発明の密封材組成物は、適度な柔軟性を有しているため、容器蓋の容器体への巻締め等の加工性にも優れている。しかも、本発明の金属容器用密封材組成物は水性分散体であることから、密封材の物性にも優れ、かつ溶剤の揮散等による作業環境の悪化もなく取扱い性にも優れているという利点がある。 In the present invention, by using a combination of an acrylonitrile butadiene elastomer and a styrene butadiene elastomer as an elastomer component as a sealing material composition for a metal container made of an elastomer, not only a good solvent such as toluene but also alcohols, motor oils, etc. Even when used as a metal container lid containing a poor solvent as a content, it is possible to form a sealing material excellent in sealing performance and durability without a decrease in weight (volume) of the sealing material over a long period of time. . Moreover, since the sealing material composition of this invention has moderate softness | flexibility, it is excellent also in workability, such as winding to the container body of a container lid. In addition, since the metal container sealing material composition of the present invention is an aqueous dispersion, it has excellent physical properties of the sealing material, and is excellent in handling properties without deterioration of the working environment due to evaporation of the solvent, etc. There is.
本発明においては金属容器用密封材組成物を構成するエラストマーとして、アクリロニトリルブタジエンエラストマー（ＮＢＲ）にスチレンブタジエンエラストマー（ＳＢＲ）を組み合わせで用いることが重要な特徴である。
アクリロニトリルブタジエンエラストマーは耐溶剤性に優れたエラストマーであるが、前述した通り、形成される膜質が硬いため軟化剤を多量に必要とし、かかるアクリロニトリルブタジエンエラストマーに軟化剤を配合して成る密封材組成物においては、軟化剤が内容物である溶剤に溶出する一方、アクリロニトリルブタジエンエラストマーがこれらの内容物により膨潤して密封材全体としてはプラスになって、密封性能を保持している。しかしながら、アクリロニトリルブタジエンエラストマーの膨潤性は内容物によって変化することから常に一定の密封性能を保持することが困難になっていた。
In the present invention, it is an important feature that an acrylonitrile butadiene elastomer (NBR) and a styrene butadiene elastomer (SBR) are used in combination as an elastomer constituting the metal container sealing material composition.
The acrylonitrile butadiene elastomer is an elastomer excellent in solvent resistance, but as described above, since the formed film is hard, a large amount of softening agent is required, and a sealing material composition comprising such an acrylonitrile butadiene elastomer blended with a softening agent. In, the softener is eluted in the solvent, which is the content, while the acrylonitrile butadiene elastomer is swollen by the content and becomes positive as the whole sealing material, and maintains the sealing performance. However, since the swellability of acrylonitrile butadiene elastomer varies depending on the contents, it has been difficult to always maintain a certain sealing performance.
本発明においては、アクリロニトリルブタジエンエラストマーにスチレンブタジエンエラストマーを組み合わせで用いることにより、内容物がモーターオイルのような貧溶媒である場合にもアクリロニトリルブタジエンエラストマーから成る密封材の重量低下及び体積低下を防止できることを見出し、密封性及び耐久性に顕著に優れた金属容器用密封材組成物を提供することが可能になったのである。
またスチレンブタジエンエラストマーはアクリロニトリルブタジエンエラストマーに比して軟らかいため、スチレンブタジエンエラストマーが軟化剤としての役目を果たすので、密封材の巻締性を向上させることができると共に、溶出の恐れのあるロジン系樹脂等からなる軟化剤の量を低減させることが可能となる。
In the present invention, by using a styrene butadiene elastomer in combination with an acrylonitrile butadiene elastomer, it is possible to prevent a decrease in weight and volume of a sealing material made of acrylonitrile butadiene elastomer even when the content is a poor solvent such as a motor oil. It has become possible to provide a sealing material composition for a metal container that is remarkably excellent in heading, sealing property and durability.
Also, since styrene butadiene elastomers are softer than acrylonitrile butadiene elastomers, styrene butadiene elastomers serve as a softening agent, so that it is possible to improve the tightness of the sealing material, and there is a risk of elution rosin resin It is possible to reduce the amount of the softening agent composed of the like.
本発明の上述した作用効果は後述する実施例の結果からも明らかである。
すなわちアクリロニトリルブタジエンエラストマー（ＮＢＲ）ラテックス及び軟化剤、充填剤から成る密封材組成物（比較例１及び３）、ＮＢＲラテックス及び充填剤から成り、軟化剤が配合されていない密封材組成物（比較例２）を用いて密封材を形成した容器においては、内容物がトルエン、エタノールでは密封材の重量変化は何れもプラスになっているが、内容物がモーターオイルでは、何れも重量変化がマイナスになり、密封材が痩せてしまっていることが理解される。また、ＮＢＲラテックスが所定量配合されていない密封材組成物（比較例４）を用いて密封材を形成した容器においては、いずれの内容物でも密封材の膨潤性が大きく、密封材のスクイズ（はみ出）を起こし、形成された密封材が満足する密封性を有していなかった。これに対し、エラストマー成分としてＮＢＲラテックスとＳＢＲラテックスを組み合わせた密封材組成物（実施例１乃至６）では、充填剤や軟化剤の配合量にかかわらず、全ての密封材組成物でトルエンやエタノールのみならずモーターオイルを内容物とする場合にも重量変化がプラスになっており、密封材がやせることなく膨潤していることが明らかである。
The above-described operational effects of the present invention are also apparent from the results of the examples described later.
That is, a sealing material composition composed of acrylonitrile butadiene elastomer (NBR) latex, a softener, and a filler (Comparative Examples 1 and 3), a sealing material composition composed of NBR latex and a filler, and containing no softener (Comparative Example) 2) When the sealant is formed using 2), the weight change of the sealant is positive when the contents are toluene and ethanol, but the weight change is negative when the contents are motor oil. It is understood that the sealing material has been thinned. Moreover, in the container which formed the sealing material using the sealing material composition (Comparative Example 4) in which a predetermined amount of NBR latex was not blended, the squeeze of the sealing material (seal ( The sealing material thus formed did not have satisfactory sealing properties. On the other hand, in the sealing material composition (Examples 1 to 6) in which NBR latex and SBR latex are combined as an elastomer component, toluene or ethanol is used in all sealing material compositions regardless of the amount of filler or softener. In addition, when the motor oil is used as the content, the weight change is positive, and it is clear that the sealing material is swollen without loss.
またエラストマー成分としてＮＢＲラテックス及びＳＢＲラテックスを使用し、軟化剤を配合しない密封材組成物においては（実施例３及び５）、密封材のＪＩＳ Ａ硬度が７０及び７５であり、軟化剤を配合しなくても密封材として必要な柔軟性を有しているのに対し、エラストマー成分としてＮＢＲラテックスのみを使用し、軟化剤を配合しない密封材組成物においては（比較例２）、ＪＩＳ Ａ硬度が８８と密封材としては硬く、巻締性に劣っており、このことより、ＳＢＲラテックスが軟化剤としての役割を果たしていることも明らかである。 Moreover, in the sealing material composition which uses NBR latex and SBR latex as an elastomer component and does not contain a softening agent (Examples 3 and 5), the sealing material has a JIS A hardness of 70 and 75, and contains a softening agent. In the case of a sealing material composition that uses only NBR latex as an elastomer component and does not contain a softening agent (Comparative Example 2), the JIS A hardness is low. 88 is hard as a sealing material and inferior in tightening property. From this, it is also clear that SBR latex plays a role as a softening agent.
本発明の容器端用密封材組成物においては、エラストマー成分としてＮＢＲ及びＳＢＲを水性分散液として用いることが重要な特徴であり、乳化重合により得られたＮＢＲラテックスとＳＢＲラテックスを好適に用いることができる。
ＮＢＲとしては、一般にアクリロニトリル含有量が、２５乃至４３重量％、特に３１乃至３６重量％のＮＢＲであることが好ましい。上記範囲よりもアクリロニトリル含有量が多いと、密封材として必要な柔軟性が失われ、密封性及び巻締性が低下し、一方上記範囲よりアクリロニトリル含有量が少ないと、内容物による重量及び体積低下を十分に防止できず密封性及び耐久性が低下する。
またＮＢＲラテックスは固形分濃度が２０乃至８０重量％の範囲、平均粒径が０．０１乃至１．０μｍの範囲、粘度が１０乃至３、０００ｍＰａ・ｓの範囲にあることが好ましい。
In the container end sealant composition of the present invention, it is an important feature that NBR and SBR are used as an aqueous dispersion as an elastomer component, and NBR latex and SBR latex obtained by emulsion polymerization are preferably used. it can.
NBR is generally preferably NBR having an acrylonitrile content of 25 to 43% by weight, particularly 31 to 36% by weight. If the acrylonitrile content is higher than the above range, the necessary flexibility as a sealing material is lost, and the sealing and winding properties are reduced. On the other hand, if the acrylonitrile content is lower than the above range, the weight and volume due to the contents are reduced. Cannot be sufficiently prevented, and the sealing performance and durability deteriorate.
The NBR latex preferably has a solid content in the range of 20 to 80% by weight, an average particle size in the range of 0.01 to 1.0 μm, and a viscosity in the range of 10 to 3,000 mPa · s.
ＳＢＲとしては、一般にスチレン含有量が２０乃至６０重量％、特に２５乃至５５重量％のものを使用することが好ましい。上記範囲よりもスチレン含有量が多いと軟化剤としての役割を果たすことができず、一方スチレン含有量が少ないと良溶媒に対し膨潤度が大きく、密封材がスクイズし、形成された密封材が満足する密封性及び巻締性を有することが困難になる。
また、ＳＢＲとして、トルエン不溶分（ゲル分）が１０乃至８０％、特に５０〜８０％であることが好ましい。上記範囲よりもトルエン不溶分が多いとトルエンなどの良溶媒に対し溶解度が小さく、トルエン不溶分が少ないと軟化剤としての役割を果たすことができず、形成された密封材が満足する密封性および巻締性を有することが困難となる。
また、ＳＢＲラテックスは固形分濃度が２０乃至８０重量％の範囲、平均粒径が０．０１乃至１．０μｍの範囲、粘度は１０乃至３、０００ｍＰａ・ｓの範囲にあることが好ましい。
SBR having a styrene content of 20 to 60% by weight, particularly 25 to 55% by weight is preferably used. If the styrene content is higher than the above range, it cannot serve as a softening agent, while if the styrene content is low, the degree of swelling with respect to a good solvent is large, the sealing material is squeezed, and the formed sealing material is It becomes difficult to have satisfactory sealing and tightening properties.
Moreover, as SBR, it is preferable that toluene insoluble content (gel content) is 10 to 80%, especially 50 to 80%. If the toluene-insoluble content is larger than the above range, the solubility in a good solvent such as toluene is small, and if the toluene-insoluble content is small, it cannot serve as a softening agent, and the formed sealing material satisfies the sealing property and It becomes difficult to have winding properties.
The SBR latex preferably has a solid content in the range of 20 to 80% by weight, an average particle size in the range of 0.01 to 1.0 μm, and a viscosity in the range of 10 to 3,000 mPa · s.
ＮＢＲ及びＳＢＲは、何れもカルボキシル化されたものも使用することができ、これにより形成される膜の硬さを調整することができる。カルボキシル化ＮＢＲのカルボン酸量は０．５乃至６．０重量％、カルボキシル化ＳＢＲのカルボン酸量は０．５乃至６．０重量％の範囲にあることが好ましい。 NBR and SBR can both be carboxylated and can adjust the hardness of the film formed thereby. The amount of carboxylic acid in carboxylated NBR is preferably in the range of 0.5 to 6.0% by weight, and the amount of carboxylic acid in carboxylated SBR is preferably in the range of 0.5 to 6.0% by weight.
ＮＢＲ及びＳＢＲの配合量は、ＮＢＲが全エラストマー量１００重量部に対し５５乃至９５重量部、特に６０乃至８０重量部の量で配合されていることが好ましく、この範囲となるように、用いるＮＢＲラテックス及びＳＢＲラテックスの固形分濃度及び配合量を調整する。全エラストマー中のＮＢＲの量が上記範囲よりも多いと前述した密封材の重量減少を防止することができないと共に、密封材が硬くなりすぎて密封性及び巻締性に欠けるようになる。また上記範囲よりもＮＢＲの量が少ないと、密封材が柔らかくなりすぎて、耐久性や機械的強度に劣るようになる。 The blending amount of NBR and SBR is preferably such that NBR is blended in an amount of 55 to 95 parts by weight, particularly 60 to 80 parts by weight, with respect to 100 parts by weight of the total elastomer. The solid content concentration and blending amount of latex and SBR latex are adjusted. If the amount of NBR in the total elastomer is larger than the above range, the above-described weight reduction of the sealing material cannot be prevented, and the sealing material becomes too hard and lacks sealing performance and winding performance. On the other hand, if the amount of NBR is less than the above range, the sealing material becomes too soft, resulting in poor durability and mechanical strength.
密封材組成物中には、従来公知の軟化剤、充填剤、老化防止剤、粘稠剤、分散剤を配合することが好ましい。また、密封材組成物中には、従来公知のラテックス、加硫剤（架橋剤）、加硫促進剤、顔料等を配合することができる。
これに限定されるものではないが、本発明において好適に使用できる上記添加剤を例示すると、軟化剤としてはロジン、水素添加ロジン、及びこれらのエステル類及び硬化ロジンのようなロジン系樹脂、テルペン系樹脂、Ｃ５，Ｃ９石油系樹脂及びクロマンインデン樹脂等、充填剤として、酸化アルミニウム水和物、酸化アルミニウム、アルミナホワイト、コロイダルシリカ、無水ケイ酸、含水ケイ酸および合成ケイ酸塩のようなシリカ質充填剤、タルク、ドロマイト、硫酸アルミナ、硫酸バリウム、炭酸マグネシウム、ケイ酸マグネシウム、酸化マグネシウム、硫酸カルシウム、フライアシュ、軽石粉、ガラス粉、アスベスト、珪藻土、ベントナイト等、または、有機物粉体およびこれらかならる中空粒子等、老化防止剤としては、ＮＮジ−β−ナフチル−Ｐ−フェニルジアミン、２，２−メチレン−ビス−〔６−（１−メチルシクロヘキシルーｐ―クレゾール）〕、ヒンダードフェノール系還元物質、ビタミンＥ系還元物質、粘調剤としては、メチルセルロース、ヒドロキシポロピルメチルセルロース、ヒドロキシエチルセルロース、カルボキシメチルセルロース、アルギン酸塩（ナトリウム、亜鉛）、ポリビニルアルコール、ポリアクリル酸ナトリウムおよびカラヤガム等、分散剤としては、オレイン酸、ステアリン酸、パルチミン酸、ラウリン酸、ミスチリン酸等の脂肪酸；ロジン酸のような樹脂酸；あるいはアルキルアリルスルホン酸、ニ塩基性脂肪酸エステルのスルホン酸塩、脂肪族アミドのスルホン酸、等の有機スルホン酸；以上の酸のナトリウム塩、カリウム塩あるいはアンモニウム塩、ラテックスとしては、天然ラテックス、イソプレンラテックス、ブタジエンラテックス、ブチルラテックスをＮＢＲラテックス及びＳＢＲラテックスにブレンドすることも可能である。加硫剤（架橋剤）としては、硫黄、含硫黄化合物、有機化酸化物、金属酸化物、有機多価アミン、変性フェノール樹脂等、加硫促進剤としては、チウラム系、ジチオ酸塩系、キンサート系等、加硫促進助剤として、酸化亜鉛、脂肪酸等、顔料として、カーボンブラック、酸化チタン等を挙げることができる。
これらの添加剤は従来公知の処方に従って配合することができるが、本発明においては、特にエラストマー成分としてＮＢＲにＳＢＲを組み合わせで用いていることからロジン系等の軟化剤の配合量を低減させることや配合しないことが可能であり、エラストマー成分（ラテックスにおける固形分）１００重量部に対し、ロジン系等の軟化剤の量を０乃至３０重量部、特に５乃至２０重量部とすることができる。
