Description

本発明は、気化性防錆剤を含み、エアゾール状に噴霧して使用する防錆剤組成物に関する。   The present invention relates to a rust inhibitor composition that contains a vaporizable rust inhibitor and is used by spraying in an aerosol form.

一般的な防錆剤には、防錆油や気化性防錆剤などがある。防錆油は、防錆対象物の金属表面に塗布して油膜を形成することにより、大気中における変色や錆の発生を防止する油脂のことである。防錆油の塗布により金属製品を一時的に錆から守る方法は、手軽且つ安価であり、しかも特別な技術を要しないため、古くから非常に多くの分野で利用されている。   Common rust preventives include rust preventive oils and vaporizable rust preventives. A rust preventive oil is an oil and fat that prevents discoloration and rust generation in the atmosphere by applying an oil film to a metal surface of a rust preventive object. The method of temporarily protecting metal products from rust by applying rust preventive oil has been used in many fields since ancient times because it is easy and inexpensive and does not require special techniques.

しかし、防錆油は、上述したように簡易で安価であるという利点を有しているが、用済み後の油膜の拭き取りに多大な手間と時間を要するという欠点がある。特に防錆箇所が可動部分である場合、例えば射出成形機の突き出しピンなどにおいては、一旦塗布した防錆油を完全に除去することは困難である。更に、防錆油の油膜の除去が不完全である場合には、残った防錆油が他の部分に付着して、汚染をもたらす可能性もある。   However, although the rust preventive oil has the advantage of being simple and inexpensive as described above, there is a drawback that it takes a lot of labor and time to wipe off the used oil film. In particular, when the rust-preventing part is a movable part, it is difficult to completely remove the once applied rust-preventing oil, for example, in an ejection pin of an injection molding machine. Furthermore, if the removal of the oil film of the rust preventive oil is incomplete, the remaining rust preventive oil may adhere to other parts and cause contamination.

一方、気化性防錆剤は、それ自体がガス化して密閉空間内に充満し、その密閉空間内にある防錆対象物の金属表面に対して防錆効果を発揮するものである。気化性防錆剤は、ガス化した防錆剤成分が金属表面を覆うため、直接塗布する必要がない。また、防錆対象物を密閉空間から出す際に、用済みの防錆剤を除去する必要がないか若しくは除去が非常に簡易である。このような利点から、機械部品や自動車部品などを保管、搬送又は輸送する際の防錆剤としては、防錆油よりも気化性防錆剤が好まれている。   On the other hand, the vaporizable rust preventive agent gasifies itself and fills the sealed space, and exerts a rust preventive effect on the metal surface of the rust preventive object in the sealed space. The vaporizable rust inhibitor does not need to be applied directly because the gasified rust inhibitor component covers the metal surface. Moreover, when taking out a rust prevention target object from sealed space, it is not necessary to remove a used rust preventive agent, or removal is very simple. Because of these advantages, a vaporizable rust preventive is preferred over a rust preventive oil as a rust preventive when storing, transporting or transporting mechanical parts, automobile parts, and the like.

上記気化性防錆剤は、VCI(Volatile Corrosion Inhibitor)あるいはVRI(Volatile Rust Inhibitor)と公用語化されている。従来から知られている気化性防錆剤としては、粉末状ないしペレット状などのほか、紙あるいは合成樹脂フィルムに塗布又は含浸したものがあり、それぞれ気化性防錆紙あるいは気化性防錆フィルムとも呼ばれている。   The vaporizable rust preventive is officially designated as VCI (Volatile Corrosion Inhibitor) or VRI (Volatile Rust Inhibitor). Conventionally known vaporizable rust preventives include powders or pellets, as well as those coated or impregnated on paper or synthetic resin film, which are both vaporizable rust preventive paper and vaporizable rust preventive film, respectively. being called.

例えば、特開2001−031966号公報や特開2003−213462号公報には、粉末状の気化性防錆剤、あるいは粘結剤を含有させて粒状ないし錠剤状とした気化性防錆剤が記載されている。また、特公平02−57092号公報には、熱可塑性樹脂粒に発泡剤と防錆剤を含浸させたペレット状の気化性防錆剤が記載されている。更に、特開平09−031672号公報には、防錆剤成分としてブチンジオールを含有し、通気性の袋に収容された気化性防錆剤が記載されている。   For example, Japanese Patent Application Laid-Open Nos. 2001-031966 and 2003-213462 describe powdery vaporizable rust preventives or vaporizable rust preventives containing a binder to form granules or tablets. Has been. Japanese Examined Patent Publication No. 02-57092 describes a pelletizable vaporizable rust preventive agent in which thermoplastic resin particles are impregnated with a foaming agent and a rust preventive agent. Furthermore, Japanese Patent Application Laid-Open No. 09-031672 describes a vaporizable rust inhibitor containing butynediol as a rust inhibitor component and housed in a breathable bag.

しかしながら、上記した従来の気化性防錆剤は、適用場所が限られるという問題がある。即ち、これらの気化性防錆剤は、防錆剤成分が自然に気化して金属表面に付着し、薄い塗膜を形成することにより防錆効果を発揮する。そのため、保管容器内などの密閉された空間でなければ、ほとんどの防錆剤成分が大気中に拡散してしまい、充分な防錆効果を発揮することができない。例えば、ペレット状の気化性防錆剤は、金型内などの密閉空間では有効であるが、開放された空間では適用が困難である。また、ペレットなどに成形する際の加熱工程で気化性防錆剤成分が昇華し、防錆剤成分のロスが生じるという欠点も有している。   However, the above-described conventional vaporizable rust preventive has a problem that the application place is limited. That is, these vaporizable rust preventives exhibit a rust preventive effect by forming a thin coating film by spontaneously vaporizing the rust preventive component and adhering to the metal surface. Therefore, unless it is a sealed space such as in a storage container, most of the rust inhibitor components diffuse into the atmosphere, and a sufficient rust prevention effect cannot be exhibited. For example, a pellet-type vaporizable rust preventive is effective in a sealed space such as in a mold, but is difficult to apply in an open space. In addition, the vaporizable rust preventive component sublimates in the heating step when forming into pellets and the like, resulting in a loss of the rust preventive component.

また、特開平11−071471号公報には、熱可塑性樹脂中に気化性防錆剤を含有したフィルムが記載されている。この気化性防錆フィルムは、防錆対象の金属製品を包装することによって、自ら密閉空間を形成して防錆効果を発揮するものである。しかし、気化性防錆フィルムのサイズを防錆対象物の形状に応じて変更する必要があるため、一つの形態で全ての場合に適用することは難しく、簡易性に劣っている。また、フィルム状に成形する際の加熱工程において、気化性防錆剤成分が昇華するためロスが生じるという欠点も有している。   Japanese Patent Application Laid-Open No. 11-071471 describes a film containing a vaporizable rust preventive agent in a thermoplastic resin. This vaporizable rust-proof film forms a sealed space by wrapping a metal product to be rust-proofed, and exhibits a rust-proof effect. However, since it is necessary to change the size of the vaporizable rust-proof film according to the shape of the rust-proof object, it is difficult to apply it in all cases in one form, and it is inferior in simplicity. Moreover, in the heating process at the time of shaping | molding into a film form, since a vaporizable rust preventive component sublimates, it also has the fault that a loss arises.

更に、気化性防錆剤成分を有機溶剤と共に噴射剤に封入し、エアゾール状に噴射して使用するタイプのものも知られている。このタイプの従来の気化性防錆剤は、噴霧することで簡単に適用でき、用済みの防錆剤成分の除去も簡易である。しかしながら、防錆剤成分が大気中に拡散しやすいため、防錆対象物の特定箇所に噴霧したとしても、防錆剤成分が被膜として留まらず大部分が大気中に拡散してしまう。そのため、密閉空間で適用しなければ大気中に拡散する防錆剤成分の量が増え、満足すべき防錆効果が得られないという欠点があった。   Further, a type in which a vaporizable rust inhibitor component is enclosed in a propellant together with an organic solvent and sprayed into an aerosol is also known. This type of conventional vaporizable rust inhibitor can be easily applied by spraying, and removal of used rust inhibitor components is also simple. However, since the rust preventive component easily diffuses into the atmosphere, even if sprayed onto a specific portion of the rust preventive object, the rust preventive component does not remain as a film and most of it diffuses into the atmosphere. For this reason, if it is not applied in a sealed space, the amount of the rust inhibitor component that diffuses into the atmosphere increases, and a satisfactory rust prevention effect cannot be obtained.

本発明は、このような従来の事情に鑑み、簡単に適用でき且つ用済み後は簡易に除去することができるうえ、密閉空間だけでなく、開放された空間においても適用でき、高い防錆効果を有する防錆剤組成物を提供することを目的とする。   In view of such conventional circumstances, the present invention can be easily applied and can be easily removed after use, and can be applied not only in a sealed space but also in an open space, and has a high antirust effect. It aims at providing the rust preventive composition which has this.

本発明者は、上記の課題について鋭意検討した結果、時間の経過により粘着性から非粘着性に変化する液状のアクリル樹脂を発泡させ、その中に気化性防錆剤成分を含有させることにより、エアゾール形態で使用するうえ、密閉空間だけでなく開放空間においても適用可能な新しい防錆剤組成物を見出し、本発明に至ったものである。   As a result of earnestly examining the above problems, the present inventor foams a liquid acrylic resin that changes from adhesive to non-adhesive over time, and contains a vaporizable rust inhibitor component therein, The present inventors have found a new rust preventive composition that can be used in an aerosol form and can be applied not only in an enclosed space but also in an open space, and has led to the present invention.

即ち、本発明による防錆剤組成物は、エアゾール状に噴霧して使用する防錆剤組成物であって、液状のアクリル樹脂に気化性防錆成剤と噴射剤を混合したことを特徴とするものである。   That is, the rust preventive composition according to the present invention is a rust preventive composition used by spraying in an aerosol form, characterized by mixing a vaporizable rust preventive composition and a propellant into a liquid acrylic resin. To do.

上記本発明の防錆剤組成物においては、前記アクリル樹脂の配合量が組成物全体の10〜30重量%であること、あるいは前記気化性防錆剤の配合量が組成物全体の10〜20重量%であることが好ましい。また、前記噴射剤がジメチルエーテルと液化天然ガスの混合ガスであり、その配合量が組成物全体の40〜60重量%であることが好ましい。   In the said rust preventive composition of this invention, the compounding quantity of the said acrylic resin is 10 to 30 weight% of the whole composition, or the compounding quantity of the said vaporizable rust preventive agent is 10-20 of the whole composition. It is preferable that it is weight%. Moreover, it is preferable that the said propellant is a mixed gas of dimethyl ether and liquefied natural gas, and the compounding quantity is 40 to 60 weight% of the whole composition.

上記本発明の防錆剤組成物では、更に、脂肪酸、シリコーンオイル、界面活性剤、プロピレンアルコールから選ばれた少なくとも1種を含むことができる。その場合、前記脂肪酸、シリコーンオイル、界面活性剤、及びプロピレングリコールの配合量は、いずれも組成物全体の1〜5重量%であることが好ましい。   The rust preventive composition of the present invention may further contain at least one selected from fatty acids, silicone oils, surfactants, and propylene alcohol. In that case, it is preferable that the compounding quantity of the said fatty acid, silicone oil, surfactant, and propylene glycol is 1 to 5 weight% with respect to the whole composition.

本発明によれば、エアゾール状に噴霧して使用するため簡単に適用でき、用済み後は簡易に除去することが可能な、気化防錆力(初期防錆能及び長距離の有効到達性能)に優れた防錆剤組成物を提供することができる。しかも、時間の経過によりアクリル樹脂が粘着性から非粘着性に変化し、密閉空間を形成する。樹脂中で気化した防錆剤成分は大気中へはほとんど拡散することがなく、防錆対象物の表面に単分子膜の防錆被膜を形成して保持される。   According to the present invention, it can be easily applied because it is sprayed in the form of an aerosol, and can be easily removed after use (initial rust prevention ability and effective performance over long distances). It is possible to provide a rust preventive composition having excellent resistance. Moreover, the acrylic resin changes from sticky to non-sticky over time, forming a sealed space. The rust inhibitor component vaporized in the resin hardly diffuses into the atmosphere, and a monomolecular rust preventive film is formed and held on the surface of the rust preventive object.

従って、本発明の防錆剤組成物は、従来のように密閉空間だけでなく、開放された空間においても適用することができ、且つ大小や形状の如何にかかわらず幅広い防錆対象物への適用が可能である。また、防錆対象物表面に被膜として付着した防錆剤組成物は、離型性に優れるため、用済み後は簡易に除去することができる。   Therefore, the rust inhibitor composition of the present invention can be applied not only in a sealed space as in the prior art, but also in an open space, and can be applied to a wide range of rust preventive objects regardless of size or shape. Applicable. Moreover, since the rust preventive composition adhering as a film on the surface of the rust preventive object is excellent in releasability, it can be easily removed after use.

本発明の防錆剤組成物に用いる気化性防錆剤は、従来から使用されているものでよく、例えば、脂肪酸アミン塩、有機酸アミン塩、特殊脂肪酸塩、トリアゾール類、無機酸塩などを用いることができる。その中でも、脂肪酸アミン塩は、防錆効果が高く、アクリル樹脂や噴射剤との相溶性に優れているため好ましい。かかる脂肪酸アミン塩の具体例としては、ジシクロアミン、シクロヘキシルアミン、エチレンジアミン、オレイルアミン、ジドデシルアミン、ベンゾトリアゾールトリエチルアミン、ジエチルアミン、トリデシルアミン、ヘキサメチレンジアミンなどがある。   The vaporizable rust inhibitor used in the rust inhibitor composition of the present invention may be those conventionally used, such as fatty acid amine salts, organic acid amine salts, special fatty acid salts, triazoles, inorganic acid salts and the like. Can be used. Among them, fatty acid amine salts are preferable because they have a high antirust effect and are excellent in compatibility with acrylic resins and propellants. Specific examples of such fatty acid amine salts include dicycloamine, cyclohexylamine, ethylenediamine, oleylamine, didodecylamine, benzotriazole triethylamine, diethylamine, tridecylamine, hexamethylenediamine and the like.

防錆剤組成物中における気化性防錆剤の配合量は、防錆効果及びアクリル樹脂との相溶性を考慮して定めることができる。ただし、JIS K2246 5.39に準拠する気化性さび止め性試験に適合するためには、組成物全体の10重量%以上の配合量を必要とする。しかし、気化性防錆剤の配合量が組成物全体の20重量%を超えると、アクリル樹脂との相溶性が低下して析出する可能性がある。従って、気化性防錆剤の配合量は、組成物全体の10〜20重量%とすることが好ましい。   The blending amount of the vaporizable rust inhibitor in the rust inhibitor composition can be determined in consideration of the rust preventive effect and compatibility with the acrylic resin. However, in order to meet the vaporizable rust prevention test based on JIS K2246 5.39, a blending amount of 10% by weight or more of the entire composition is required. However, when the blending amount of the vaporizable rust preventive exceeds 20% by weight of the whole composition, the compatibility with the acrylic resin may be lowered and deposited. Therefore, it is preferable that the compounding quantity of a vaporizable rust preventive agent shall be 10 to 20 weight% of the whole composition.

アクリル樹脂は、気化性防錆剤成分及び噴射剤成分を包み込むことで、適度な気化性(蒸気圧)と発泡性を付与するものである。そして、アクリル樹脂を含むことによって、本発明の防錆剤組成物はエアゾール状に噴射され、防錆対象物の表面に発泡体の被膜を形成することができ、しかもアクリル樹脂は時間の経過に伴い粘着性から非粘着性に変化する。そのため、被膜中の防錆剤成分が防錆対象物の表面に留まり、大気中への拡散を減らすことができると同時に、満足すべき防錆効果を発揮する。アクリル樹脂としては、防錆剤組成物の製造時及び使用時に液状のものを用いる。   The acrylic resin imparts appropriate vaporization (vapor pressure) and foamability by enveloping the vaporizable rust inhibitor component and the propellant component. And by including an acrylic resin, the rust inhibitor composition of the present invention can be sprayed in an aerosol form to form a foam film on the surface of the rust preventive object, and the acrylic resin can be used over time. Along with the change from sticky to non-sticky. Therefore, the rust inhibitor component in the coating stays on the surface of the object to be rusted and can reduce diffusion into the atmosphere while exhibiting a satisfactory rust prevention effect. As an acrylic resin, a liquid thing is used at the time of manufacture and use of a rust preventive composition.

防錆剤組成物中のアクリル樹脂の配合量は、組成物全体の10〜30重量%が望ましい。配合量が組成物全体の10重量%未満では強固な発泡体ないし被膜が得られず、防錆剤成分が揮発しやすいため、満足すべき防錆効果が得られない。また、配合量が組成物全体の30重量%を超えると、樹脂成分が多くなるため噴射時に詰まりを生じやすい。尚、噴射剤100重量部に対する配合量では、アクリル樹脂50重量部程度が適当である。   As for the compounding quantity of the acrylic resin in a rust preventive agent composition, 10 to 30 weight% of the whole composition is desirable. If the blending amount is less than 10% by weight of the total composition, a strong foam or film cannot be obtained and the rust inhibitor component tends to volatilize, so that a satisfactory rust preventive effect cannot be obtained. Further, when the blending amount exceeds 30% by weight of the entire composition, the resin component increases, and thus clogging is likely to occur during injection. In addition, about 50 weight part of acrylic resins are suitable for the compounding quantity with respect to 100 weight part of propellants.

噴射剤は、組成物をエアゾール状に噴霧するために必要であり、その際にアクリル樹脂を発泡させる作用を有している。アクリル樹脂はジメチルエーテル(DME)ガスへの溶解性が良好であり、アクリル樹脂以外の成分は液化天然ガス(LPG)への溶解性に優れている。そのため、噴射剤としては、DMEとLPGの混合ガス(例えば、DME/LPG=70:30)の使用が好ましい。また、噴射剤の配合量は、組成物全体の40〜60重量%が望ましい。噴射剤の配合量が組成物全体の40重量%未満では、樹脂成分が多くなり、噴射時に詰まりの懸念がある。また、配合量が組成物全体の60重量%を超えると、強固な発泡体ないし被膜が得られず防錆効果に影響をもたらす。   The propellant is necessary for spraying the composition in an aerosol form, and has an action of foaming the acrylic resin at that time. The acrylic resin has good solubility in dimethyl ether (DME) gas, and components other than the acrylic resin are excellent in solubility in liquefied natural gas (LPG). Therefore, it is preferable to use a mixed gas of DME and LPG (for example, DME / LPG = 70: 30) as the propellant. The blending amount of the propellant is preferably 40 to 60% by weight of the entire composition. When the blending amount of the propellant is less than 40% by weight of the entire composition, the resin component increases, and there is a concern of clogging at the time of injection. On the other hand, if the blending amount exceeds 60% by weight of the entire composition, a strong foam or film cannot be obtained, and the rust prevention effect is affected.

本発明の防錆剤組成物は、防錆対象物を配置した密閉空間で噴霧するか、あるいは開放空間で防錆対象物に向かって噴霧することで、上述したように、防錆対象物の表面に防錆剤成分を含む発泡体の被膜を形成する。この被膜は用済み後に除去することができるが、防錆剤組成物中に脂肪酸、シリコーンオイル、界面活性剤、プロピレンアルコールから選ばれた少なくとも1種を更に含むことにより、一層簡易に除去することが可能となる。その理由は、脂肪酸、シリコーンオイル、界面活性剤、プロピレンアルコールが、いずれも金属に対する離型作用を高める可塑剤的な作用を示すからである。   As described above, the rust preventive composition of the present invention is sprayed in a sealed space where the rust preventive object is arranged or sprayed toward the rust preventive object in an open space, as described above. A foam coating containing a rust inhibitor component is formed on the surface. This film can be removed after use, but can be removed more easily by further including at least one selected from fatty acids, silicone oils, surfactants, and propylene alcohol in the rust preventive composition. Is possible. The reason is that fatty acids, silicone oils, surfactants, and propylene alcohol all exhibit plasticizer action that enhances the release action on metals.

上記脂肪酸、シリコーンオイル、界面活性剤、及びプロピレングリコールの配合量は、いずれも組成物全体の1〜5重量%が好ましい。脂肪酸、シリコーンオイル、界面活性剤、プロピレングリコールのいずれの場合も、配合量が組成物全体の1重量%未満では、金属表面に付着した発泡体ないし被膜の離型性が改善されない。また、いずれかの配合量が5重量%を超えると、発泡体が不安定になり、金属表面上に強固な発泡体の被膜を得ることが難しくなるため、防錆効果が低減する。尚、脂肪酸としては、ベヘン酸、オレイン酸、ステアリン酸、パルミチン酸、12−ヒドロキシステアリン酸などの使用が好ましい。   As for the compounding quantity of the said fatty acid, silicone oil, surfactant, and propylene glycol, all are 1 to 5 weight% of the whole composition. In any case of fatty acid, silicone oil, surfactant, and propylene glycol, if the blending amount is less than 1% by weight of the entire composition, the releasability of the foam or film attached to the metal surface is not improved. Moreover, since the foam will become unstable and it will become difficult to obtain the coating film of a strong foam on a metal surface when either compounding quantity exceeds 5 weight%, a rust prevention effect reduces. As the fatty acid, behenic acid, oleic acid, stearic acid, palmitic acid, 12-hydroxystearic acid and the like are preferably used.

気化性防錆剤の脂肪酸アミン塩としてジシクロアミン20重量%、アクリル樹脂24重量%、脂肪酸としてオレイン酸3重量%、シリコーンオイル1.5重量%、界面活性剤1.0重量%、プロピレングリコ−ル0.5重量%、及びDMEとLPGの混合ガス(DME/LPG=70:30)からなる噴射剤50重量%を、エアゾ−ル缶内で充填混合し、本発明例の防錆剤組成物を製造した。   20% by weight of dicycloamine, 24% by weight of acrylic resin, 3% by weight of oleic acid, 1.5% by weight of silicone oil, 1.0% by weight of surfactant, propylene glycol as fatty acid amine salt of vaporizable rust preventive 0.5 wt% and 50 wt% of propellant composed of a mixed gas of DME and LPG (DME / LPG = 70: 30) are filled and mixed in an aerosol can, and the rust preventive composition of the present invention example Manufactured.

この本発明例の防錆剤組成物について、JIS K2246 5.39に準拠する気化性さび止め性試験(簡便法)を行い、気相状態にある防錆剤組成物の気化防錆力を評価した。即ち、1リットルの広口瓶内に、防錆剤組成物(噴射物)と鋼(SGD3)試験片を隔てて配置し、35%グリセリン水溶液を用いて瓶内を20℃×90%RHに保った。一定時間経過後(H型は1時間、L型は20時間)、鋼試験片の表面に穿った穴部に冷水(2.0±0.5℃)を注いで鋼試験片を結露させ、更に3時間経過後に鋼試験片の発錆の有無を調べた。   About the rust preventive composition of this invention example, the vaporization rust prevention property test (simple method) based on JIS K2246 5.39 is performed, and the vaporization rust prevention power of the rust preventive composition in a gas phase is evaluated. did. That is, in a 1 liter wide-mouthed bottle, a rust inhibitor composition (sprayed material) and a steel (SGD3) test piece are placed apart, and the inside of the bottle is kept at 20 ° C. × 90% RH using a 35% glycerin aqueous solution. It was. After a certain period of time (H type is 1 hour, L type is 20 hours), cold water (2.0 ± 0.5 ° C) is poured into the hole formed in the surface of the steel test piece to condense the steel test piece. Furthermore, the presence or absence of rusting of the steel specimen was examined after 3 hours.

上記試験は鋼試験片3個で同時に行い、3個中2個以上に錆びが認められた場合に錆びの発生有りと判定する。また、鋼試験片3個中の1個に錆びが認められた場合には、再度鋼試験片3個について試験を繰り返し、再び3個中の1個以上に錆びが認められた場合に錆びの発生有りと判定する。得られた結果を下記表1に示した。尚、判定結果は、錆びの発生無しを○、錆びの発生有りを×として表示した。   The above test is performed simultaneously on three steel test pieces, and it is determined that rust has occurred when rust is observed on two or more of the three pieces. In addition, when rust is found on one of the three steel specimens, the test is repeated on three steel specimens again, and when rust is found on one or more of the three specimens, It is determined that it has occurred. The obtained results are shown in Table 1 below. In addition, the determination result was indicated as “O” when no rust was generated and “X” when rust was generated.

一方、比較例の防錆剤組成物として、一般に市販されているエアゾ−ル形態の気化性防錆剤を用い、上記と同様の気化性さび止め性試験(簡便法)を行った。この比較例の気化性防錆剤は、上記本発明例と同じ脂肪酸アミン塩に、炭化水素系溶剤と噴射剤(LPG)をエアゾ−ル缶内で充填混合したものであり、その噴射物を用いて試験を実施した。また、参考のために、防錆剤を使用しない例(ブランク)についても上記と同様に試験した。得られた結果を下記表1に併せて示した。   On the other hand, as a rust preventive composition of a comparative example, a vaporizable rust preventive agent in the form of a commercially available generally was used, and the same vaporizable rust preventive test (simple method) was performed. The vaporizable rust preventive of this comparative example is the same fatty acid amine salt as that of the above-mentioned example of the present invention, in which a hydrocarbon solvent and a propellant (LPG) are filled and mixed in an aerosol can. The test was carried out. For reference, an example (blank) in which no rust inhibitor was used was also tested in the same manner as described above. The obtained results are also shown in Table 1 below.

Figure 2007002290
Figure 2007002290

上記表1の結果から、本発明例の防錆剤組成物は、気化性さび止め試験のH型及びL型試験ともに合格することが分かった。一方、比較例である従来の気化性防錆剤は、H型試験では、3個中1個の鋼試験片に錆びが認められたため、再試験を行ったところ、同様に3個中1個に錆びが発生し、判定は不合格であった。また、L型試験では、初回の試験で不合格であった。


From the results of Table 1 above, it was found that the rust preventive composition of the examples of the present invention passed both the H-type and L-type tests of the vaporizable rust prevention test. On the other hand, the conventional vaporizable rust inhibitor as a comparative example was found to be rusted on one of the three steel specimens in the H-type test. Rust occurred, and the judgment was unacceptable. Further, the L-type test failed in the first test.
