本発明は、成形加工用マグネシウム合金板、マグネシウム合金容器およびマグネシウム合金容器の製造方法に係り、特に絞り成形性に優れた成形加工用マグネシウム合金板、限界絞り比３．５以下で絞り成形されてなるマグネシウム合金容器、および限界絞り比３．５以下で絞り成形することを特徴とするマグネシウム合金容器の製造方法に関する。 The present invention relates to a magnesium alloy plate for forming, a magnesium alloy container, and a method for producing a magnesium alloy container, and particularly, a magnesium alloy plate for forming having excellent drawability, which is drawn at a limit drawing ratio of 3.5 or less. The present invention relates to a magnesium alloy container, and a method for producing a magnesium alloy container characterized by being drawn at a limit drawing ratio of 3.5 or less.
モバイル通信機器やノートパソコンなどの携帯用電子機器においては軽量化が常に求められており、これらの機器の外装ケースとして軽量金属であるマグネシウム合金が用いられている。しかし、マグネシウム合金は加工性に乏しく、高絞り比で絞り成形する低絞り率の容器を得ることが極めて困難である。このような難加工性のマグネシウム合金を絞り加工するため、絞り成形加工装置のダイ、パンチ、シワ押え部材の温度を１５０〜４００℃程度まで加熱して絞り成形加工する方法（例えば、特許文献１参照）、ダイ、パンチ、ブランクホルダーを加熱し、これらの成形加工工具を介してマグネシウムを再結晶温度域まで加熱し、その加熱によりマグネシウムが再結晶して軟化し塑性変形しやすい焼鈍効果を誘発させながらマグネシウムブランクを箱状に熱間深絞りするマグネシウム合金製ハードケースの製造方法（例えば、特許文献２参照）などの成形加工時にマグネシウム合金を加熱する方法や、ポンチとダイの少なくとも一方の表面に、マグネシウム材の板より軟質の純マグネシウム、純アルミニウム、樹脂などの板を取り付けて塑性加工を行う方法（例えば、特許文献３参照）、加熱したマグネシウム薄板の上下面に断熱材としてテトラフルオロエチレンシートを設置して、高温でプレス成形する方法（例えば、特許文献４参照）などが提案されている。これらの提案に示されているように、マグネシウム合金に絞り加工などの成形加工を施す場合は、再結晶温度域まで加熱することが不可欠である。 Portable electronic devices such as mobile communication devices and notebook computers are always required to be lighter, and a magnesium alloy, which is a lightweight metal, is used as an outer case for these devices. However, the magnesium alloy has poor workability, and it is extremely difficult to obtain a container with a low drawing ratio that is drawn with a high drawing ratio. In order to draw such a difficult-to-work magnesium alloy, a draw forming process is performed by heating the die, punch, and wrinkle pressing member of the draw forming apparatus to about 150 to 400 ° C. (for example, Patent Document 1). See), heating the die, punch, and blank holder, and heating magnesium to the recrystallization temperature range through these forming tools, and the heating recrystallizes the magnesium and softens it, thereby inducing an annealing effect that tends to cause plastic deformation. A magnesium alloy hard case manufacturing method (for example, see Patent Document 2) in which a magnesium blank is hot-drawn in a box shape while the magnesium blank is heated, or a surface of at least one of a punch and a die A plate made of pure magnesium, pure aluminum, resin, etc., which is softer than the magnesium plate, is (For example, see Patent Document 3), a method in which a tetrafluoroethylene sheet is installed as a heat insulating material on the upper and lower surfaces of a heated magnesium thin plate, and press molding is performed at a high temperature (for example, see Patent Document 4). ing. As shown in these proposals, when a forming process such as drawing is performed on a magnesium alloy, it is essential to heat it to a recrystallization temperature range.
さらに、加工を容易にするため潤滑剤を使用することも提案されている。例えば、プレス金型の型表面に、チタンナイトライド、ダイヤモンドライクカーボンなどの超硬質膜をコーティング処理により形成させる方法（例えば、特許文献５参照）、生分解性油脂、防錆・潤滑剤、極圧添加剤、さらに有機亜鉛化合物、有機モリブデン系化合物を含有してなるマグネシウム合金またはアルミニウム合金用塑性加工油を用いて成形加工する方法（例えば、特許文献６参照）が提案されている。しかし、これらの方法はいずれも冷間加工で成形加工する場合に用いられており、上記の例におけるように、２００℃を超える加工温度で成形加工する場合には有効な潤滑効果が得られない。 It has also been proposed to use a lubricant to facilitate processing. For example, a method of forming an ultra-hard film such as titanium nitride or diamond-like carbon on the surface of a press mold by a coating process (for example, see Patent Document 5), biodegradable oils and fats, rust preventive / lubricant, pole There has been proposed a method (for example, see Patent Document 6) of forming using a plastic working oil for magnesium alloy or aluminum alloy containing a pressure additive, and further an organic zinc compound and an organic molybdenum compound. However, all of these methods are used in the case of forming by cold working, and an effective lubricating effect cannot be obtained when forming at a working temperature exceeding 200 ° C. as in the above example. .

Molding can be performed.
以下、本発明を詳細に説明する。 Hereinafter, the present invention will be described in detail.
本発明の成形加工用マグネシウム合金板の基板となるマグネシウム板としては、純マグネシウム板や、合金成分としてアルミニウムを１．０〜９．０重量％、亜鉛を０．５〜６．０重量％、マンガンを０．０５〜２．０重量％含有してなり、残部がマグネシウムおよび不可避的不純物からなるマフネシウム合金からなり、結晶粒径が２〜５０μｍ、より好ましくは２〜１０μｍであり、板厚が０．０５〜２．０ｍｍのものであることが好ましい。これらのマグネシウム合金板表面に有機樹脂を被覆して、成形加工用マグネシウム合金板とする。 As a magnesium plate used as the substrate of the magnesium alloy plate for forming according to the present invention, a pure magnesium plate or aluminum as an alloy component is 1.0 to 9.0% by weight, zinc is 0.5 to 6.0% by weight, Manganese is contained in an amount of 0.05 to 2.0% by weight, the balance is made of a magnesium and inevitable impurities, and the crystal grain size is 2 to 50 μm, more preferably 2 to 10 μm. It is preferable that it is 0.05-2.0 mm. The surface of these magnesium alloy plates is coated with an organic resin to form a magnesium alloy plate for forming.
マグネシウム合金板表面に被覆する有機樹脂としては、水溶性または水分散性樹脂であることが好ましく、水溶性ウレタン樹脂、水溶性ポリエステル樹脂、水溶性アクリル樹脂、水溶性エポキシ樹脂のいずれかであることが好ましい。これらの有機樹脂は１種のみで用いることもよいし、２種以上を混合して用いてもよい。 The organic resin coated on the surface of the magnesium alloy plate is preferably a water-soluble or water-dispersible resin, and is any one of a water-soluble urethane resin, a water-soluble polyester resin, a water-soluble acrylic resin, and a water-soluble epoxy resin. Is preferred. These organic resins may be used alone or in combination of two or more.
これらの有機樹脂は樹脂単独で上記のマグネシウム板に塗布乾燥して皮膜形成させて用いてもよいが、成形加工性や耐食性を向上させるために、下記に示す物質を有機樹脂に含有させて用いてもよい。シランカップリング剤を含有させることにより、有機樹脂皮膜のマグネシウム板に対する密着性、特に成形加工時の密着性が著しく向上する。シランカップリング剤は有機樹脂皮膜中に５重量％以下で含有していることが好ましく、１重量％以下で含有していることがより好ましい。５重量％を超えて含有しても密着性の向上効果は飽和し、経済的に有利でなくなる。 These organic resins may be used by coating and drying the above-mentioned magnesium plate alone to form a film. However, in order to improve molding processability and corrosion resistance, the following substances are used in organic resins. May be. By including a silane coupling agent, the adhesion of the organic resin film to the magnesium plate, particularly the adhesion during molding, is significantly improved. The silane coupling agent is preferably contained in the organic resin film at 5% by weight or less, more preferably 1% by weight or less. Even if the content exceeds 5% by weight, the effect of improving the adhesion is saturated, which is not economically advantageous.
また、コロイダルシリカを含有させることにより、有機樹脂皮膜の硬さが向上して耐疵付性が向上し、耐食性も向上する。コロイダルシリカは有機樹脂皮膜中に５０重量％以下で含有していることが好ましい。５０重量％を超えて含有すると、有機樹脂皮膜が硬くなりすぎて、有機樹脂皮膜の加工性が劣化し、成形加工時に有機樹脂皮膜にクラックが生じやすくなる。 Moreover, by including colloidal silica, the hardness of the organic resin film is improved, the scratch resistance is improved, and the corrosion resistance is also improved. The colloidal silica is preferably contained in the organic resin film at 50% by weight or less. If the content exceeds 50% by weight, the organic resin film becomes too hard, the workability of the organic resin film deteriorates, and cracks are likely to occur in the organic resin film during molding.
さらに、潤滑剤を含有させることにより、マグネシウム板に有機樹脂皮膜を形成させた成形加工用マグネシウム合金板の成形加工性が向上する。潤滑剤としては、ラウリン酸、ミリスチン酸、パルミチン酸、ステアリン酸などの高級脂肪酸、これらの高級脂肪酸のカルシウム塩、アルミニウム塩、亜鉛塩、バリウム塩、マグネシウム塩、これらの高級脂肪酸エステル、ポリエチレンワックス、ポリプロピレンワックスなどのポリオレフィンワックス、ポリテトラフルオロエチレン、ポリクロロトリフルオロエチレン、ポリフッ化ビニリデン、ポリフッ化ビニルなどのフッ素系ワックス、グラファイト、二硫化モリブデン、ボロンナイトライドなどの無機質粉末などを用いることができる。これらの潤滑剤は有機樹脂皮膜中に２０重量％以下で含有していることが好ましい。２０重量％を超えて含有すると、マグネシウム板に対する有機樹脂皮膜の成形加工時も密着性が劣化する。上記のシランカップリング剤、コロイダルシリカ、潤滑剤は有機樹脂皮膜中にそれぞれ１種で単独で含有していてもよいが、２種以上が含有していてもよい。 Furthermore, by including a lubricant, the moldability of the magnesium alloy plate for molding in which an organic resin film is formed on the magnesium plate is improved. Lubricants include higher fatty acids such as lauric acid, myristic acid, palmitic acid, stearic acid, calcium salts of these higher fatty acids, aluminum salts, zinc salts, barium salts, magnesium salts, higher fatty acid esters thereof, polyethylene wax, Polyolefin wax such as polypropylene wax, fluorine-based wax such as polytetrafluoroethylene, polychlorotrifluoroethylene, polyvinylidene fluoride, and polyvinyl fluoride, inorganic powder such as graphite, molybdenum disulfide, and boron nitride can be used. . These lubricants are preferably contained in the organic resin film at 20% by weight or less. When the content exceeds 20% by weight, the adhesion deteriorates even during the molding process of the organic resin film on the magnesium plate. Said silane coupling agent, colloidal silica, and lubricant may be contained individually by 1 type in the organic resin film, respectively, but 2 or more types may contain them.
上記のようにして得られる有機樹脂を、純マグネシウム板やマグネシウム合金板の少なくとも片面に、好ましくは両面に塗布乾燥して有機樹脂皮膜を形成させる。有機樹脂皮膜の厚さは乾燥後の厚さで０．１〜３０μｍであることが好ましく、１〜１０μｍであることがより好ましい。このようにして本発明の成形加工用マグネシウム合金板が得られる。 The organic resin obtained as described above is applied to and dried on at least one side, preferably both sides, of a pure magnesium plate or magnesium alloy plate to form an organic resin film. The thickness of the organic resin film is preferably 0.1 to 30 μm, more preferably 1 to 10 μm after drying. In this way, the magnesium alloy plate for forming according to the present invention is obtained.
以上のようにして得られる本発明の成形加工用マグネシウム合金板は成形加工性に優れており、絞り加工時にこれまで常用されていた潤滑油や二硫化モリブデンなどの固体潤滑剤を用いることなく、好適に容器に成形することができる。また、これまで常用されていた潤滑油や二硫化モリブデンなどの固体潤滑剤を用いても好適に容器に成形することができる。さらに、成形加工用マグネシウム合金板を３５０℃以下の温度範囲、好ましくは２００〜３５０℃の温間加工温度範囲に加熱して絞り加工すると絞り加工性が向上し、底径に比較して側壁長の大きい容器に成形することが可能となる。しかし、２００℃を超える温度範囲で成形加工する場合、有機樹脂皮膜が分解して変色したり皮膜にクラックが生じ、見栄えが劣化するとともに絞り比を向上させることが困難になる。そのため、有機樹脂皮膜にさらに耐熱性付与剤を含有させることにより、２００〜３５０℃以下の高温の温間加工温度範囲で有機樹脂皮膜が変色したり、クラックを生じることなく、安定して成形加工を行うことが可能となり、絞り比も向上させることができる。 The magnesium alloy sheet for forming according to the present invention obtained as described above is excellent in forming processability, without using a solid lubricant such as lubricating oil or molybdenum disulfide that has been conventionally used at the time of drawing, It can be suitably formed into a container. Moreover, it can be suitably formed into a container using a solid lubricant such as lubricating oil or molybdenum disulfide which has been conventionally used. Further, when the magnesium alloy sheet for forming is heated to a temperature range of 350 ° C. or less, preferably 200 to 350 ° C. and drawn, the drawability is improved, and the side wall length is longer than the bottom diameter. Can be formed into a large container. However, when molding is performed in a temperature range exceeding 200 ° C., the organic resin film is decomposed and discolored or cracks are generated in the film, so that the appearance is deteriorated and it is difficult to improve the drawing ratio. Therefore, by adding a heat resistance imparting agent to the organic resin film, the organic resin film can be stably molded without causing discoloration or cracking in the high temperature processing temperature range of 200 to 350 ° C. or less. And the aperture ratio can be improved.
耐熱性付与剤としては、ポリイミドなどの耐熱性樹脂やシロキサン化合物を用いることが好ましい。シロキサン化合物としては、ジメチルシロキサン、ジエチルシロキサン、メチルエチルシロキサン、ジフェニルシロキサン、メチルフェニルシロキサンなどのオルガノシロキサンのポリマーやモノマー、またはこれらのオルガノシロキサン分子内にポリアルキレンオキシド基、水酸基、アミド基、カルボキシル基、スルホン基、アミノ基のいずれか１種または２種以上の置換基を１個以上有するものが好適に用いられる。これらの耐熱性付与剤は、有機樹脂皮膜中に５〜８０重量％含有されていることが好ましく、１０〜６０重量％含有されていることがより好ましい。このように、有機樹脂皮膜中に耐熱性付与剤を含有させることにより、成形加工用マグネシウム合金板を２００〜３５０℃の温間加工温度範囲まで加熱し、絞り比３．５程度の高い絞り比で、底径に比較して側壁長の大きいマグネシウム合金容器に絞り成形加工することが可能となる。なお、耐熱性付与剤は有機樹脂に単独で含有してもよいが、上記のシランカップリング剤、コロイダルシリカ、潤滑剤のいずれか１種、または２種以上と併用して含有していてもよい。 As the heat resistance imparting agent, it is preferable to use a heat resistant resin such as polyimide or a siloxane compound. Examples of the siloxane compound include polymers and monomers of organosiloxanes such as dimethylsiloxane, diethylsiloxane, methylethylsiloxane, diphenylsiloxane, and methylphenylsiloxane, or polyalkylene oxide groups, hydroxyl groups, amide groups, and carboxyl groups in these organosiloxane molecules. , One having at least one substituent of at least one of a sulfone group and an amino group is preferably used. These heat resistance imparting agents are preferably contained in the organic resin film in an amount of 5 to 80% by weight, and more preferably 10 to 60% by weight. Thus, by including a heat resistance imparting agent in the organic resin film, the magnesium alloy plate for forming is heated to a warm working temperature range of 200 to 350 ° C., and a high drawing ratio of about 3.5 is drawn. Thus, it becomes possible to draw and process a magnesium alloy container having a longer side wall length than the bottom diameter. The heat resistance imparting agent may be contained alone in the organic resin, but may be contained in combination with one or more of the above silane coupling agent, colloidal silica, and lubricant. Good.
このようにして得られるマグネシウム合金容器は、有機樹脂皮膜上に塗装を施すことが可能である。あるいは上記の成形加工用マグネシウム合金板の有機樹脂皮膜上に予め塗装を施しておいた塗装板を成型加工してマグネシウム合金容器としてもよい。また、容器に成形した後にアルカリ溶液を用いて有機樹脂皮膜を溶解除去したり、研磨粒子を表面に吹き付けるショットブラスト法を用いて除去し、陽極酸化処理やめっきなどの表面処理を施すことも可能である。 The magnesium alloy container thus obtained can be coated on the organic resin film. Or it is good also as a magnesium alloy container by carrying out the shaping | molding process of the coating board which gave the coating beforehand on the organic resin film of said magnesium alloy board for shaping | molding process. In addition, after forming into a container, it is possible to dissolve and remove the organic resin film using an alkaline solution, or to remove it using a shot blasting method in which abrasive particles are sprayed on the surface, and to perform surface treatment such as anodic oxidation or plating. It is.

比較用として、上記のマグネシウム合金板、およびマグネシウム合金板の両面に５０μｍの厚さのテトラフルオロエチレンフィルムを取付けたものを同様の条件で絞り加工し、限界絞り比を求めた。なお、テトラフルオロエチレンフィルムを取付けないマグネシウム合金板の場合、常温での加工性が極めて劣っており、潤滑油や固体潤滑剤を用いても絞り加工することが困難であるので、ダイス温度およびブランクホルダー温度が２００℃以上の場合にのみ絞り加工した。また、テトラフルオロエチレンフィルムを取付けたマグネシウム合金板の場合、ダイス温度およびブランクホルダー温度が３５０℃であるとテトラフルオロエチレンフィルムの損傷が激しく絞り加工することが困難であるので、ダイス温度およびブランクホルダー温度が１５０〜３００℃の場合にのみ絞り加工した。 For comparison, the above-described magnesium alloy plate and a magnesium alloy plate attached with a tetrafluoroethylene film having a thickness of 50 μm were drawn under the same conditions to obtain a limit drawing ratio.

Drawing was performed only when the holder temperature was 200 ° C. or higher. In the case of a magnesium alloy plate with a tetrafluoroethylene film attached, if the die temperature and the blank holder temperature are 350 ° C., the tetrafluoroethylene film is severely damaged and difficult to be drawn. Drawing was performed only when the temperature was 150 to 300 ° C.
