用出来難い問題があった。(Prior Art) In recent years, the field of products that use prime movers, such as automobiles and home appliances, has expanded. As the scope of use has expanded, the value of these products has been evaluated from many angles, and many new technologies have been added in response. Among these, one of the evaluation criteria that has been particularly emphasized recently is quietness and low vibration. Damping steel plates are purposefully and advantageously applied to this purpose in place of conventional steel plates. Since the resin used in damping steel plates is non-conductive, conventional spot welding, seam welding, and
There was a problem in that it was difficult to apply electric resistance welding methods such as projection welding as they were.

困難である。Various methods have been proposed for imparting welding performance to objects in which resin is sandwiched between steel plates. For example, JP-A-58-191154 discloses a method in which a conductive circuit is formed by using a deformed plate as at least one of the front and back metal plates and substantially bringing the front and back metal plates into contact.
In a laminated board in which a synthetic resin is interposed between two metal plates, a spiral conductor is placed in this resin layer at a volume ratio of 3 to 30.
In Japanese Patent Application Laid-Open No. 58-142845, there is a method in which metal fibers are mixed in a volume ratio of 3 to 30% with respect to the resin instead of the spiral conductor. but,
With either method, it is difficult to ensure industrially stable weldability.

A vibration-damping steel plate with excellent welding performance using resin added with metal powder that is 0W or less and has a fluidity of 150g for 18 to 30 seconds as specified in JIS Z 2502, and 2) - In item 1) The metal powder to be applied is stainless steel powder, iron powder,
The present invention relates to a vibration-damping steel plate with excellent welding performance, which is characterized by applying copper powder, nickel powder, and zinc powder alone, in a mixture, or in an alloyed form.

０ ＪＬが実用］二最も多いようである。The thickness of the resin layer of the damping steel plate according to the present invention is 10 to 150 J.
The resin thickness is more preferably in the range of 30 to 70 pL. Normally, laminated steel plates for the purpose of weight reduction,
The thickness of the resin layer sandwiched between the metal plates is 150 to 1000 g, more generally 200 to 60 g, since the purpose is to reduce the weight.
0 JL seems to be the most common.

ギーを熱エネルギーに変換・放散する効果が急激に減衰

低下するので好ましくない。If the resin thickness of the vibration-damping steel plate that is the subject of the present invention becomes 10p or less, the vibration-damping performance of the resin, that is, the effect of converting and dissipating external vibration energy into thermal energy, will be rapidly attenuated. This is not preferable because the adhesive force that effectively restrains the steel plate also decreases rapidly.

い。Even if the resin thickness exceeds 150 p-, the damping performance itself will not deteriorate, but since the resin is used, the resin will be relatively soft, and the processing formability of the damping steel plate will deteriorate due to the lack of strength of the resin.
That is, there is a disadvantage that the influence of the low shear resistance of the resin appears, and furthermore, even if an excellent conductive filler is added to the resin, there is a disadvantage that the variation in welding performance becomes large.

~30 seconds 150g, using stainless steel powder, iron powder, copper powder, nickel powder, zinc powder, singly or in combination, or metal powder alloyed with these metals as necessary. It is. The metal powder according to the present invention is present in the resin layer and acts effectively as an electrical conductor during welding, resulting in spot welding, which has been widely put into practical use industrially.
It can be used for resistance welding such as series welding, projection welding, and seam welding under almost the same conditions as conventional cold-rolled steel sheets.

接電流が殆ど流れない場合のある事を確認した。It would be most convenient if the resin itself could be given conductive properties of the degree necessary for resistance welding, but at present it is almost impossible to obtain such a resin on an industrial scale and at a low cost. . From this point of view, adding conductive substances to the resin,
There is a method of dispersing the welding current to form a conductive circuit, but as a result of the inventor's study, these conventional methods result in parts that can be electrically welded and parts that cannot be electrically welded, and in extreme cases, welding where almost no welding current flows I confirmed something.
制振鋼板を工業的に実用化するには、溶接作業の安定性
が極めて重要である事は論を待たない。It goes without saying that the stability of welding work is extremely important in order to commercialize damping steel plates industrially.
本発明者は、樹脂中に導電性付与剤として分散せしめた
、金属粒子の導電特性を詳細に研究した結果、この金属
粒子が導電剤として有効に作用するには、次の３つの要
件が必要である事を見出した。As a result of detailed research on the conductive properties of metal particles dispersed in resin as a conductivity imparting agent, the present inventor found that the following three requirements are necessary for the metal particles to function effectively as a conductivity agent. I found that.
１）樹脂膜厚と金属粒子のサイズの比
２）金属粒子の量（樹脂中の分散量）
３）金属粒子と表皮材との接触
勿論、樹脂中に分散せしめた金属粒子がほぼ均一に分散

脂厚が厚くなるに従い、大きくする必要があるが、樹脂
厚／金属粒子サイズ比が２以下、より好ましくは１．０
５以下で有効な導電回路の形成ができる。1) Ratio of resin film thickness to metal particle size 2) Amount of metal particles (amount dispersed in resin) 3) Contact between metal particles and skin material, as well as almost uniform dispersion of metal particles dispersed in resin It is a prerequisite that you have done so. The metal particle (powder) size needs to be increased as the resin thickness increases, but the resin thickness/metal particle size ratio is 2 or less, more preferably 1.0.
An effective conductive circuit can be formed when the number is 5 or less.

。If the addition ratio (weight ratio) of metal particles is increased to about 80% or more, the above restrictions become almost unnecessary, but when the addition ratio of metal particles becomes this high, the difference between resin and skin steel plate The addition ratio of metal particles should be 60% or less, since this will cause disadvantages such as inhibition of adhesion and reduction of the vibration damping performance of the resin (measured as the loss coefficient of the vibration damping steel plate). The lower limit of the addition ratio of metal particles changes depending on the particle size distribution of the metal powder. That is, the higher the proportion of the part with larger particle size, the lower the addition ratio may be. In order to exhibit the resin's inherent vibration damping performance and adhesion performance with the skin steel plate, the addition ratio of metal powder should be 60% (by weight) or less, and in order to obtain resistance welding suitability, it should be at least 3% (by weight). It should be less than %.
本発明の最も大きな特徴は、金属粒子と表皮鋼板との界
面の接触、及び金属粒子相互の接触を、導電性を確保す

本格的な通電を開始することになる。The most significant feature of the present invention is that the contact at the interface between the metal particles and the skin steel plate and the contact between the metal particles are made in the most desirable form in order to ensure conductivity. The surface of the metal particles dispersed or suspended in the resin is covered with the resin, which is a dispersion medium. During resistance welding, the skin steel plate is pressurized with an electrode tip, electrode ring, etc. Conductivity is required when this electrode is applied, and as a result, the resin layer is heated and softened or partially disappears due to the initial energization, allowing contact between the skin steel plates.
Full-scale energization will begin.

皮鋼板類、及び金属粉相互の電気的連結が可能になる。Therefore, the role of the metal powder in the present invention is that it is possible to form a conductive circuit during the welding process, especially up to the 3rd to 4th cycle from the start of welding, using equipment and welding conditions that are almost the same as those for normally used welding of steel plates. The point is to get used to it. In order for metal powder whose surface is coated with a resin layer to form a conductive circuit during the initial welding process, the pressure applied by the electrode during welding removes this resin coating layer or partially tears it, leaving bare metal. A vehicle is required that exposes the particle surface. This makes it possible to electrically connect the metal powder, the skin steel plates, and the metal powder to each other.

っても何等差支えない。In this way, in order to form a conductive circuit by applying local pressure with an electrode, it is not possible if the metal powder surface is smooth; it must have jagged micro-irregularities or a macroscopically acute surface shape. become. One of the measures indicating the surface profile of this metal powder is the fluidity defined by JIS. The present invention achieves excellent welding performance by adjusting the fluidity range of metal powder to 1.
(2) It is necessary to have a particle size of 80 pL or less and 150 g for 18 to 30 seconds. The fluidity of a spherical metal powder with a smooth surface (particle size of 80JL or less) is 150g for 13 to 14 seconds, and damping steel plates to which this metal powder is applied have an abnormally high initial resistance during electric welding.
Almost no electricity is applied and welding is not possible. The metal powder used in the present invention may be, for example, elliptical, cubic, rectangular, rod-shaped, or block-shaped.
