Description
本発明は、鉄鋼材あるいは銅やアルミニウム、亜鉛メッキなどの非鉄金属からなる素材や部品を保管あるいは輸送中に、その表面が酸化されて錆が発生するのを抑制する防錆フィルムに関するものである。 The present invention relates to a rust-preventing film that suppresses generation of rust due to oxidation of the surface during storage or transportation of materials or parts made of steel, or non-ferrous metals such as copper, aluminum, and galvanizing. .
鉄鋼材あるいは、銅やアルミニウム、亜鉛メッキなどの非鉄金属からなる素材や部品、製品（以下「金属製品」という）を保管、輸送している間に、空気中の酸素と水分によって金属製品の表面の酸化が進み製品としての価値がなくなる場合がある。このような発錆を防ぐために金属製品の表面に防錆油を塗布したり、フィルムで金属製品を包装して気化性防錆剤のタブレットを同封したり、防錆紙や防錆フィルムで包装をしたりしている。これらの中でも防錆フィルムは透明で外部から内容物が視認でき水分の浸入も防げるので金属製品の包装に幅広く使用されている。 While storing and transporting materials, parts, and products (hereinafter referred to as “metal products”) made of steel, or non-ferrous metals such as copper, aluminum, and galvanizing, the surface of metal products is affected by oxygen and moisture in the air. Oxidation of the product may lead to loss of product value. In order to prevent such rusting, rust preventive oil is applied to the surface of metal products, metal products are wrapped with a film and a vaporizable rust preventive tablet is enclosed, or wrapped with rust-proof paper or rust-proof film Or doing. Among these, the rust preventive film is transparent and can be seen from the outside, and can prevent moisture from entering, so it is widely used for packaging metal products.
このような防錆フィルムとしては亜硝酸塩とアンモニウム化合物あるいは、尿素化合物を各層に含むポリオレフィン樹脂からなることを特徴とする多層防錆フィルムがある（特許文献１）。しかしこの方法では安定した防錆性を有する防錆フィルムを作成することが難しいため、必要以上に防錆成分（亜硝酸ナトリウム、安息香酸アンモニウム、尿素）などを添加する必要がある。 As such a rust preventive film, there is a multilayer rust preventive film characterized by comprising a polyolefin resin containing nitrite and an ammonium compound or a urea compound in each layer (Patent Document 1). However, since it is difficult to produce a rust-proof film having a stable rust-proof property by this method, it is necessary to add an anti-rust component (sodium nitrite, ammonium benzoate, urea) or the like more than necessary.
また、水溶性ガラス粉末と、ジシクロヘキシルアミン安息香酸塩などの気化性防錆剤を熱可塑性樹脂に含有させた金属防錆用包装フィルムも提案されている（特許文献２）。しかし防錆性が安定しないという問題とガラス粉末がフィルムから脱落するという問題がある。 Further, a metal rust-proof packaging film in which a water-soluble glass powder and a vaporizable rust preventive such as dicyclohexylamine benzoate are contained in a thermoplastic resin has also been proposed (Patent Document 2). However, there is a problem that the rust prevention property is not stable and a problem that the glass powder falls off from the film.
さらに特許文献３にはアミン・カルボン酸塩と、芳香族カルボン酸塩を含むポリオレフィン系防錆フィルムが開示され、亜鉛に対しては優れた防錆効果を示すが、他金属に対して防錆性が安定しないという問題がある。 Further, Patent Document 3 discloses a polyolefin-based rust-preventing film containing an amine carboxylate and an aromatic carboxylate, and exhibits an excellent rust-preventing effect against zinc, but rust-proof against other metals. There is a problem that sex is not stable.
特許文献４には活性酸化亜鉛粉末と塩基性炭酸亜鉛粉末を含む防錆フィルムが開示されている。特許文献４は硫黄含有ガスからの腐食を防ぐフィルムであり、通常の他腐食性ガスからの防錆効果は不十分である。 Patent Document 4 discloses a rust preventive film containing an active zinc oxide powder and a basic zinc carbonate powder. Patent Document 4 is a film that prevents corrosion from a sulfur-containing gas, and is not sufficiently effective in preventing rust from other corrosive gases.
本発明は、防錆効果に優れ内容物が外部から視認でき防錆剤の脱落の少ない防錆フィルムを提供するものである。 The present invention provides a rust-preventing film which has an excellent rust-preventing effect and whose contents can be visually recognized from the outside, and in which the rust-preventing agent is less dropped.
本発明者らは上記課題を解決するために鋭意検討した結果、防錆剤成分のフィルム中の分散度合いを制御することで、防錆効果が発現することを発見し本発明を完成するに至った。

Two types of salts include dicyclohexylamine / nitrite, monoethanolamine / benzoate, dicyclohexylamine / benzoate, diisopropylammonium / benzoate, diisopropyl / nitrite, cyclohexylamine / benzoate, etc. It is done.
ポリオレフィン系樹脂に対する防錆剤の配合量は０．３質量％以上、１０質量％以下が好ましく、０．４質量％以上６質量以下が寄り好ましく、０．５質量％以上４質量％以下が最も好ましい。防錆剤が１０質量％を超えると防錆効果が向上しないばかりか防錆剤の脱落が激しくなり好ましくない。また防錆剤の配合量が０．３％未満だと防錆効果が不十分となる。 The blending amount of the rust inhibitor with respect to the polyolefin resin is preferably 0.3% by mass or more and 10% by mass or less, more preferably 0.4% by mass or more and 6% by mass or less, and most preferably 0.5% by mass or more and 4% by mass or less. preferable. When the rust inhibitor exceeds 10% by mass, not only the rust preventive effect is improved but also the rust preventive agent drops off, which is not preferable. Moreover, when the compounding quantity of a rust preventive agent is less than 0.3%, a rust prevention effect will become inadequate.
ポリオレフィン系樹脂に防錆剤を混練する方法は特に限定されないが、一般の混練機が使用できる。混練機としては単軸押出機、二軸押出機、バンバリー式混練機、ロール式混練機、インテンシブミキサーなどが好適に使用できる。混練時の防錆剤の配合量はフィルム成形時の配合量より防錆剤を多く配合してマスターバッチとして作成するのが一般的である。混練時の防錆剤の配合量としては５％以上５０％以下が好ましい。防錆剤が５０％を超えると流動性が低下し好ましくない。また、防錆剤の配合量が５％未満となると流動性がなくなり生産性が低下して好ましくない。 The method of kneading the rust inhibitor with the polyolefin resin is not particularly limited, but a general kneader can be used. As the kneader, a single screw extruder, a twin screw extruder, a Banbury kneader, a roll kneader, an intensive mixer, and the like can be suitably used. The compounding amount of the rust inhibitor at the time of kneading is generally prepared as a master batch by blending more rust inhibitor than the compounding amount at the time of film forming. The blending amount of the rust inhibitor during kneading is preferably 5% or more and 50% or less. If the rust inhibitor exceeds 50%, the fluidity is lowered, which is not preferable. Moreover, when the compounding quantity of a rust preventive agent will be less than 5%, fluidity | liquidity will lose | disappear and productivity will fall and it is unpreferable.
本発明においては防錆剤のフィルム中の分散状態を制御することが防錆性を効率よく発揮するために重要である。防錆剤の分散状態がフィルムのヘーズに反映されるため、ヘーズで表すと２０％以上、５０％以下が好ましく、２５％以上、４５％以下がさらに好ましく、３０％以上、４０％以下が特に好ましい。ヘーズが５０％を超えると透明性が低下し視認性が悪くなったり防錆剤が脱落する原因となる。ヘーズが２０％未満になると防錆性が悪化する。ヘーズを小さくするためには混練回数を増やしたり混練のシェアを大きくすることなどで制御可能である。またヘーズを大きくするためには同様に適度な混練条件を見出すことで制御可能である。 In the present invention, it is important to control the dispersion state of the rust inhibitor in the film in order to efficiently exhibit the rust prevention property. Since the dispersion state of the rust inhibitor is reflected in the haze of the film, it is preferably 20% or more and 50% or less when expressed in haze, more preferably 25% or more and 45% or less, particularly 30% or more and 40% or less. preferable. When the haze exceeds 50%, the transparency is lowered and the visibility is deteriorated or the rust preventive agent is dropped. When the haze is less than 20%, the rust prevention property deteriorates. In order to reduce the haze, it is possible to control by increasing the number of kneading times or increasing the share of kneading. Similarly, in order to increase the haze, it can be controlled by finding appropriate kneading conditions.
ポリオレフィン系樹脂フィルム中の防錆剤の粒子径は平均で１０μｍ〜１０００μｍが好ましく、３０μｍ〜７００μｍがさらに好ましく５０μｍ〜５００μｍが好ましい。１０μｍ未満になると防錆性が悪化する。１０００μｍを超えるとフィルムから防錆剤が脱落しやすくなる。
本発明の防錆フィルムの厚さは２０μｍ〜１００μｍが好適である。２０μｍ未満になると防錆性が悪化し１００μｍ以上になると防錆効果が向上せず透明性が低下して視認性が悪くなる。
The particle diameter of the rust inhibitor in the polyolefin resin film is preferably 10 μm to 1000 μm on average, more preferably 30 μm to 700 μm, and preferably 50 μm to 500 μm. When it is less than 10 μm, the rust prevention property deteriorates. When it exceeds 1000 μm, the rust preventive agent easily falls off from the film.
The thickness of the rust-proof film of the present invention is preferably 20 μm to 100 μm. When the thickness is less than 20 μm, the rust prevention property is deteriorated. When the thickness is 100 μm or more, the rust prevention effect is not improved and the transparency is lowered and the visibility is deteriorated.
