〈産業上の利用分野〉
本発明は、スポット溶接が可能な樹脂複合型制振鋼板に
関するものである。DETAILED DESCRIPTION OF THE INVENTION <Industrial Application Field> The present invention relates to a resin composite damping steel plate that can be spot welded.
〈従来の技術〉
金属フィラー入り樹脂複合型制振鋼板は、スポット溶接
が可能なために、自動車、建材、家電製品に使用されて
いる。<Prior Art> Resin composite damping steel sheets containing metal fillers are used in automobiles, building materials, and home appliances because they can be spot welded.
とりわけ、芯材樹脂として制振性を有する熱硬化性樹脂
を使用することは、例えば特開昭６３−７４６３４号公
報に示されているように、接着強度が良好であり、加工
性が向上するとともに塗装時の耐熱性が向上する。In particular, the use of a thermosetting resin having damping properties as the core material resin provides good adhesive strength and improves workability, as shown in JP-A No. 63-74634, for example. At the same time, heat resistance during painting is improved.

埋没する結果となり、やはり溶接性の低下を招くためと
考えられる。However, the use of thermosetting resins has the advantage of heat resistance,
Although solvent resistance was improved, a decrease in spot weldability was unavoidable. This is because thermosetting resins generally have higher film strength than thermoplastic resins, and this resin remains between the filler and the steel plate, and the resin cannot be removed only by the pressure applied during spot welding. In addition, if the pressurizing force during bonding is increased to eliminate the resin between the filler and the steel plate during manufacturing, if the filler is too soft than the hardness of the steel plate, only the filler will deform greatly and become buried in the resin. This is thought to be due to a decrease in weldability.

く作用〉
サンドインチ型樹脂複合制振鋼板のスポット溶接性が熱
硬化性樹脂を使用した場合に、低下するメカニズムにつ
いて本発明者等は鋭意研究した結果、以下のようなこと
を見出した。Effects> As a result of extensive research into the mechanism by which the spot weldability of a sandwich-type resin composite damping steel sheet is reduced when a thermosetting resin is used, the present inventors have discovered the following.
樹脂複合型制振鋼板の製造時において、熱硬化性樹脂は
、硬化剤と主剤を溶剤に熔解した混合物に金属粉をさら
に混合してスキン銅板上に塗工している。また樹脂のみ
を先に塗工し、そこに金属粉を混入する方法もあるがい
ずれにしろ、これらを圧着する場合にこの金属粉と鋼板
の間に樹脂が残留する。これは金属粉の形状や貼り合わ
せ時の加圧力等によって変わってはくるが、やはり樹脂
の残留は認められる。When producing a resin composite vibration damping steel plate, the thermosetting resin is a mixture of a curing agent and a base resin dissolved in a solvent, which is further mixed with metal powder, and then applied onto the skin copper plate. Alternatively, there is a method in which only resin is applied first and metal powder is mixed therein, but in either case, when these are pressed together, the resin remains between the metal powder and the steel plate. This varies depending on the shape of the metal powder, the pressure applied during bonding, etc., but residual resin is still observed.
これは、樹脂に熱可塑性樹脂を使用した場合も同様であ

に対し、熱硬化性樹脂の場合には、熱可塑性樹脂よりも

。This is also the case when thermoplastic resin is used as the resin, but with thermoplastic resin, this resin can be removed by the pressure applied during spot welding, so there was almost no problem, whereas heat In the case of hardening resin, the resin film has higher strength than thermoplastic resin, so the resin is not removed between the steel plate and the filler during spot welding, and even if the filler is present, it cannot be used as a current path. It was unable to fulfill its role and was linked to welding defects such as sparks.

従って、熱硬化性樹脂を使用した樹脂複合型制振鋼板の

あるが、樹脂を柔らかくすることは、熱硬化性樹脂を使
用するメリットがなくなるために、本発明では、製造時
にフィラーと鋼板間に残留する樹脂を最小限に抑制する
手段を選んだ。Therefore, in order to improve the weldability of resin-composite damping steel plates using thermosetting resin, it is necessary to soften the film strength to the extent that the resin can be removed during welding, or to increase the weldability between the filler and the steel plate during manufacturing. It is important to sufficiently remove the resin, but since softening the resin eliminates the advantage of using thermosetting resin, in the present invention, the resin remaining between the filler and the steel plate during manufacturing is removed. We chose a method to minimize it.
ここで樹脂の排除は、貼り合わせ時の圧力、加圧時間、
樹脂の粘性に依存している。これらの関係は定性的には
以下の（１）弐に従う。Here, the removal of resin depends on the pressure during bonding, the pressurization time,
It depends on the viscosity of the resin. Qualitatively, these relationships follow (1) 2 below.
１／△Ｈ２ｃｃ Ｐ ｔ ／ ｖ −−−−一−−−
−−−−−−（１）但し、△Ｈ：残留樹脂厚、Ｐ：加圧
力、ｔ；時間、シ：樹脂粘性である。1/△H2cc P t / v ------1---
--------(1) However, ΔH: residual resin thickness, P: pressing force, t: time, C: resin viscosity.
ここで樹脂の粘性は、樹脂の硬化度合い・温度等でコン
トロール可能である。出来る限り残留樹脂厚を低減する
には、粘性を小さくすればよいが、小さすぎると押し出
し後の回り込みがある。しかしいずれにしても樹脂の粘
性は樹脂を選択すれば一義的に決定される。Here, the viscosity of the resin can be controlled by the degree of curing of the resin, temperature, etc. In order to reduce the residual resin thickness as much as possible, the viscosity may be reduced, but if the viscosity is too small, wraparound may occur after extrusion. However, in any case, the viscosity of the resin is uniquely determined by the selection of the resin.
加圧力は、フィラーと鋼板間の樹脂の排除に役立つパラ
メーターであり、加圧力は大きければ大きい方が樹脂の
排除には好ましい。しかしながらここでフィラーの硬度
が綱板の硬度より小さいと加圧力が大きくなった時、鋼
板は変形しないでフィラーが変形する。このためにフィ
ラーの変形量が大きくなり、樹脂中に埋もれる現象が起
きる。The pressurizing force is a parameter useful for removing resin between the filler and the steel plate, and the larger the pressurizing force is, the better for removing the resin. However, if the hardness of the filler is smaller than the hardness of the steel plate, when the pressing force becomes large, the filler deforms without deforming the steel plate. For this reason, the amount of deformation of the filler increases, and a phenomenon occurs where the filler is buried in the resin.
こうなるとフィラーと鋼板は接触不良となり溶接性が不
良となる。このため加圧力に制限を受けることになり結
局弱い加圧力では樹脂の排除不足を招き溶接不良となる
。逆に、フィラーの硬度が鋼板の硬度を上回ると、フィ
ラーは変形しないで、鋼板のほうにフィラーが食い込む
形となるために、かなり高い加圧力まで耐えることがで
き、この場合には良好な溶接性を得ることができる。If this happens, there will be poor contact between the filler and the steel plate, resulting in poor weldability. For this reason, the applied force is limited, and if the applied force is weak, the resin will not be sufficiently removed, resulting in defective welding. On the other hand, if the hardness of the filler exceeds the hardness of the steel plate, the filler will not deform and will bite into the steel plate, allowing it to withstand a fairly high pressure, resulting in good welding.

本発明では、マイクロビッカース硬度１００〜２００の
綱板をスキン鋼板として採用し、該鋼板より大なるマイ
クロビッカース硬度を有するＮｉ粒子を導電性粒子とし
て採用したので、加圧圧着の際に銅板のほうにフィラー
が食い込む理想的な形状をとり得る。In the present invention, a steel plate with a micro-Vickers hardness of 100 to 200 is used as a skin steel plate, and Ni particles having a micro-Vickers hardness greater than that of the steel plate are used as conductive particles. The filler can take on an ideal shape.
フィラーとしてＮ１粉を選択したのは、比較的硬度の高
いものが容易に入手できかつ、金属とじての融点がスキ
ン材として使用される綱仮に近いためである。すなわち
電流経路として存在する金属フィラーは、発熱して、溶
解する場合に、スキン材よりも早く溶解すると、電流経
路を遮断される恐れがあるためである。N1 powder was selected as the filler because it is easily available with relatively high hardness and its melting point as a metal is close to that of rope used as a skin material. That is, if the metal filler existing as a current path generates heat and melts, and if it melts faster than the skin material, the current path may be interrupted.
本発明に使用する樹脂は熱硬化性樹脂の範回において、
例えば熱硬化性ポリエステル樹脂、エボキン樹脂、ポリ
ウレタン樹脂、アクリル樹脂等が良い。これらの樹脂は
単独で使用しても良いが、硬化系を共通に選択できるな
らば混合しても良い。In the range of thermosetting resins, the resin used in the present invention includes:
For example, thermosetting polyester resin, Evokin resin, polyurethane resin, acrylic resin, etc. are preferable. These resins may be used alone, or may be mixed if a common curing system can be selected.
また、フィラーの粒径と樹脂厚の比を大きく取ることに
よりフィラーが変形する間に樹脂が流動する時間を稼く
ことができるので、樹脂の排除に有利である。従って本
発明の熱硬化性樹脂の場合、従来言われていたフィラー
平均径と樹脂厚の比１．２〜２．０より大きい１．６〜
３．０に限定した。望ましくは、フィラー径と樹脂厚の
比が２．０以上の方が溶接性が向上する。一方、フィラ
ー径と樹脂厚の比が３．０超では、フィラーの変形が大
きくなりすぎ、フィラーが樹脂中に埋没し、スポット溶
接が不可能となる。Further, by setting a large ratio between the particle size of the filler and the thickness of the resin, it is possible to buy time for the resin to flow while the filler is deformed, which is advantageous for removing the resin. Therefore, in the case of the thermosetting resin of the present invention, the ratio of filler average diameter to resin thickness is 1.6 to 1.6, which is larger than the conventionally said ratio of 1.2 to 2.0.
It was limited to 3.0. Desirably, weldability is improved when the ratio of filler diameter to resin thickness is 2.0 or more. On the other hand, if the ratio of the filler diameter to the resin thickness exceeds 3.0, the deformation of the filler becomes too large, the filler is buried in the resin, and spot welding becomes impossible.
また。この他の溶接性の向上方法としては、フィラーの
配合量を増加させることが挙げられるが、フィラー−個
に掛かる加圧力Ｆは以下の（２）式に示される。Also. Another method for improving weldability is to increase the blending amount of filler, and the pressing force F applied to each filler is expressed by the following equation (2).
Ｆ＝Ｐ／ｇ −−−−−−−・−−−−−−−−・
−−−−−（２）但し、Ｐ：加圧力１ｇ：単位面積あた

-----(2) However, P: Pressure force 1 g: Number of fillers per unit area.
このように、フィラー−個にかかる加圧力はフィラーの
個数が多くなると減少するためにフィラーと鋼板間の樹
脂の排除が不十分となり、結局フィラーの個数分のバイ
パス回路の形成に繋がらず、却って溶接性の低下を招く
、従って配合量もできる限り低く抑えた方が良いが、あ
まり少ないとバイパス回路に過大電流が流れスパークと
なって表皮鋼板のとけおちを招くので好ましくない。In this way, the pressurizing force applied to the filler decreases as the number of fillers increases, so the removal of resin between the filler and the steel plate becomes insufficient, and in the end, it does not lead to the formation of a bypass circuit for the number of fillers. It causes deterioration of weldability, so it is better to keep the amount mixed as low as possible, but if it is too small, excessive current will flow in the bypass circuit and cause sparks, which will lead to melting of the skin steel plate, which is not preferable.
そこで、本発明では、樹脂層中のＮｉ粒子の配合量を０
．２〜３．０νｏｆ％に限定した。Therefore, in the present invention, the amount of Ni particles in the resin layer is reduced to 0.
．． It was limited to 2 to 3.0 νof%.

Polyurethane resin, acrylic resin, etc. are good. These resins may be used alone, or may be mixed if a common curing system can be selected.

As the copper plate of 0 to 200, a normal hot-rolled film plate or cold-rolled steel plate can be used, and the surface treatment is carried out within a range that does not affect the above-mentioned Vickers hardness, such as 4-metal treatment or phosphate chemical conversion treatment. It is also possible to use materials with increased adhesiveness.
