乙の発明は、スポット溶接性に優れた樹脂ラミネート鋼
板に関する。[Detailed Description of the Invention] [Industrial Application Field] The invention of Part B relates to a resin-laminated steel plate with excellent spot weldability.
２枚の鋼板間に合成樹Ｈ６層を配して形成する合成樹脂
ラミネート鋼板は、制振性能の面で優れた効果を発揮す

各分野において急速に普及しつつある。Synthetic resin laminated steel sheets, which are formed by placing a synthetic H6 layer between two steel sheets, have been recognized to have excellent vibration damping performance, and are currently being used in various fields such as automobiles, electrical machinery, and building materials. It is rapidly becoming popular in Japan.

化されつつある。Currently, conductive particles such as graphite, iron, copper, zinc, or aluminum are mixed into the synthetic resin layer (

Techniques that enable direct spot welding without the complicated contrivances of the conventional techniques as described above have been developed and are being put into practical use.
〔発明が解決しようとする従来の問題点〕ところが、こ
のような改良されているはずの合成樹脂ラミネート鋼板
であっても、そのスポット溶接性についてはいまだに解
決しなければならない問題が次に示す通り存在しおり、
さらに改良の余地が残されているものであった。[Conventional problems to be solved by the invention] However, even with synthetic resin laminated steel sheets that are supposed to have been improved, there are still problems with spot weldability that need to be solved, as shown below. existence bookmark,
There was still room for further improvement.
（１）使用する導電性粒子自体に起因する問題当然のこ
とながら、使用する導電性の粒子は高い伝導度を有し、
しかも、その表面は長期にわたり酸化されにくいもので
あることことが要求される。(1) Problems caused by the conductive particles used Naturally, the conductive particles used have high conductivity,
Moreover, the surface is required to be resistant to oxidation for a long period of time.
また、溶接時のような高温加熱下においても同様の性能
を維持しつづける乙との可能なものであることが必要で
ある。In addition, it is necessary that the same performance can be maintained even under high-temperature heating such as during welding.
しかしながら、現在市販されている合成樹脂ラミネート
鋼板では、いまだに十分な導電性を有しているとは言え
ず、とくにアルミニウム、鉄、銅などの金属粉では、取
扱いいかんによっては酸化による皮膜生成によって導電
性がたびたび阻害されていた。However, the synthetic resin laminated steel sheets currently on the market still cannot be said to have sufficient electrical conductivity.In particular, metal powders such as aluminum, iron, and copper may become conductive due to the formation of a film due to oxidation depending on how they are handled. Sexuality was often inhibited.
（２）溶接時に異常抵抗値が発生する問題スポット溶接
の電圧印下時においては、各導電性粒子は異状加熱を起
こさないような均一抵抗値を有しかつ導電性の面から低
抵抗値を有することが必要である。(2) Problem of abnormal resistance value occurring during welding When voltage is applied during spot welding, each conductive particle has a uniform resistance value that does not cause abnormal heating, and a low resistance value from the viewpoint of conductivity. It is necessary to have
しかしながら、従来の導電性粒子ではその高硬度あるい
は粒径の相違により導電性粒子と鋼板との「なじみ」の
差や接触状態の差などの影響を受け、均一な抵抗値を有
しているとは言いがたかつた。However, conventional conductive particles do not have a uniform resistance value due to their high hardness or differences in particle size, and are affected by differences in "fitting in" and contact conditions between the conductive particles and the steel plate. It was hard to say.
このため、鋼板の孔あき（ピンホール）や黒シミ （ピ
ンホール直前の状態での鋼板表面の点状ブルーイング）
など、不均一発熱欠陥が避は難かった。For this reason, holes (pinholes) in the steel plate and black stains (point-like bluing on the surface of the steel plate immediately before the pinhole) occur.
It was difficult to avoid uneven heating defects.
このような問題点を克服するために種々検討を行った結
果、３０〜１００μｍ厚の合成樹脂層に対してその合成
樹脂層の厚さ（ｄ）に対して粒径が０．８〜１．５ｄで
ある軟金属粉または軟金属合金粉の合成樹脂の０．２〜
３．０容量％に当たる量を混合してある合成樹脂層を鋼
板間に圧着して形成した樹脂ラミネー１−鋼板、が有効
であることを知った。As a result of various studies to overcome these problems, we found that for a synthetic resin layer with a thickness of 30 to 100 μm, the particle size is 0.8 to 1.5 μm relative to the thickness (d) of the synthetic resin layer. 0.2 to 5d of synthetic resin of soft metal powder or soft metal alloy powder
It has been found that a resin laminate 1-steel plate formed by pressing a synthetic resin layer mixed in an amount equivalent to 3.0% by volume between steel plates is effective.
この発明では、上述のように鋼板の間に合成樹脂を挾ん
で使用するが、この合成樹脂としては、酸および酸無水
物、シランカップリング剤などにより変性した熱可塑性
樹脂またはエポキシ樹脂などの熱硬化性樹脂などを使用
することができる。In this invention, a synthetic resin is sandwiched between steel plates as described above, and the synthetic resin is a thermoplastic resin or an epoxy resin modified with an acid, an acid anhydride, a silane coupling agent, etc. A curable resin or the like can be used.
ここて使用する合成樹脂の厚さｄは、その両外−５＝
側に配する鋼板の厚さによっても変化するがおよそ３０
〜１００μｍの範囲が適当である。The thickness d of the synthetic resin used here varies depending on the thickness of the steel plates placed on both sides of the synthetic resin, but is approximately 30 mm.
A range of 100 μm is suitable.
この厚さが３０μｍを下回ると、充分な制振性の効果を
期待することができないし、また逆に、１００μｍを超
えて厚くすると、制振性の挙動が厚みの増加に伴わなく
なり、割振性の向上傾向は、特にある一定値以上では見
られなくなって経済性の面からみて好ましくない結果と
なる。If the thickness is less than 30 μm, sufficient damping effect cannot be expected, and conversely, if it is thicker than 100 μm, the vibration damping behavior will no longer follow the increase in thickness, resulting in poor vibration allocation. The tendency to improve is no longer seen especially above a certain value, which is an unfavorable result from an economical point of view.
さらに、樹脂厚さが大であることから成形性が劣化する
ばかりでなく、加えて溶接時などの熱を受けることによ
り樹脂のガス化する機会が多くなり、溶接部に「ふくれ
」等を生じて外観不良の原因となる。Furthermore, since the resin is thick, not only does moldability deteriorate, but in addition, there are many opportunities for the resin to gasify when exposed to heat during welding, resulting in "blister" etc. at the welded part. This may cause poor appearance.
この発明に従って導電化粒子を合成樹脂に配合するにあ
たっては、例えば、導電化粒子として次の表に示した物

使用するのが好ましい。Lead 37 Tin 7-12 Zinc 36 Antimony 35-62 Nickel 96 Stainless steel Approximately 200 Iron 100 However, due to the need to satisfy conditions such as high electrical conductivity and oxidation resistance, as well as improved contact and adhesion with steel sheets, the comparative terms and conditions It is preferable to use metals selected from the group of metals from lead to anotymone and their alloys in the above table.
思上のような制約条件に合致した材料による粉体は、平

相当する粒径のものを、合成樹脂に対して０．２〜３．
０容量％配合することにより好ましい結果を期待するこ
とができる。Powder made from a material that meets the above-mentioned constraint conditions is one whose particle size corresponds to 0°8 to 1.5d with respect to the thickness d of the smooth synthetic resin. .2-3.
Favorable results can be expected by incorporating 0% by volume.
軟金属粉の配合量は、樹脂ラミネート鋼板の物性に大き
く影響を及ぼすため、乙の範囲は最低限の導電性が確保
できる混合量を下限値とし、接着剥離強度が低下する添
加量を上限値として設定すればよい。The blending amount of soft metal powder has a large effect on the physical properties of the resin-laminated steel sheet, so the lower limit of the range B is the mixing amount that ensures the minimum conductivity, and the upper limit is the amount that reduces the adhesive peel strength. You can set it as .
上述した軟金属粉を配合してある合成樹脂を鋼板とラミ
ネートシた状態を示したものが第１図である。FIG. 1 shows a state in which a synthetic resin containing the above-mentioned soft metal powder is laminated with a steel plate.
図中、１は鋼板、２は合成樹脂層、３は軟金属粉を示し
ており、ラミネ−１・加圧時において軟金属粉は軟かい
がゆえに押潰されて鋼板とほどよく接触して接触面積は
大きくなり、かつ接触は安定する。In the figure, 1 is a steel plate, 2 is a synthetic resin layer, and 3 is a soft metal powder.At the time of lamination 1 and pressurization, the soft metal powder is crushed because it is soft and makes good contact with the steel plate. The contact area becomes large and the contact becomes stable.
このことによりスポット溶接時の電流経路を安定的に確
保することができ良好な溶接が可能となる。This makes it possible to stably secure a current path during spot welding, allowing for good welding.
第３図は、従来の樹脂ラミネート鋼板を示した図であっ
て、図中、４は導電性粒子を示している。FIG. 3 is a diagram showing a conventional resin-laminated steel plate, and in the figure, 4 indicates conductive particles.
この場合は、使用している導電性粒子が硬い物質（Ｃ，
Ｎｉ、ステンレス）であるために、ラミネート加圧時に
十分な圧潰が起こらず、鋼板との接触面積が小さくなり
、かつ接触状態は不安定であることが理解できる。In this case, the conductive particles used are hard substances (C,
It can be seen that because the material is (Ni, stainless steel), sufficient crushing does not occur during lamination pressurization, the contact area with the steel plate becomes small, and the contact state is unstable.
上記のようにして形成した樹脂ラミネート鋼板は、導電

気伝導性が確保されていると共に、軟金属粉と鋼板との
接触状態をも広くかつ安定に制御しうるため、低くかつ
均一な電気抵抗値を有する樹脂ラミネート鋼板となって
いる。Since the resin-laminated steel sheet formed as described above uses soft metal powder as conductive particles, it not only ensures high electrical conductivity but also widens the contact between the soft metal powder and the steel sheet. Moreover, since it can be stably controlled, the resin-laminated steel sheet has a low and uniform electrical resistance value.

ような低くかつ均一な抵抗値をもつこの樹脂ラミネ−１
・鋼板によりその発生を未然に防止することが可能であ
る。Welding defects caused by abnormal heating of conductive particles can be avoided by using this resin laminate 1, which has such a low and uniform resistance value.
・It is possible to prevent this from occurring using steel plates.

The heated steel plate 13 is bonded to one side of the steel plate 13 through a roll 14, and then reheated in a heating furnace 12 to be bonded to another steel plate 13.
There are two methods: one is to cover the exposed film surface with the film and then press-bond it with a roll 14, and the other is to directly apply a synthetic resin containing conductive particles to a steel plate and then bond it to another steel plate. There are two types.

る。This invention provides a resin-laminated steel plate with high electrical conductivity in its intermediate resin layer, with a thickness of 0.8% relative to the thickness d of the synthetic resin.
Since the resin laminated steel sheet is constructed using soft metal powder with a particle size equivalent to ~1.5d mixed in the resin layer in an amount of 0.2 to 3% by volume, it is more effective than conventional conductive particles. This improves the contact state of the steel plates and increases the degree of adhesion, making it possible to produce resin-laminated steel plates with uniform resistance and low resistance.
