されている。(Prior Art) In recent years, there has been an increasing demand for quiet operation of automobiles, building materials, home appliances, etc. Various methods can be considered as specific methods for suppressing vibration under practical conditions, but one effective method is to provide a high-resistance vibration damping section between the vibration source and the vibration transmitting/receiving side. For this reason, so-called sandwich-type (or restraint-type) vibration damping steel plates, in which a resin having a sticky characteristic is sandwiched between steel plates, are partially used for such applications.

しこれらの樹脂は。The vibration-damping resin, which has excellent vibration-suppressing ability, has appropriate viscoelastic properties in the relevant temperature range, and converts externally applied vibrations into thermal energy, etc. through shearing of resin constituent molecules and other deformation, and releases it. This effectively suppresses vibration. But these resins.

にあたって最大の問題であった。Just like general resin, it has lower conductivity than cold-rolled steel sheets and various plated steel sheets, making it difficult to perform electric resistance welding such as spot welding, seam welding, and projection welding, which was the biggest problem in putting it into practical use. .

ている。A method to solve this problem is to form a conductive circuit during welding by dispersing conductive substances such as iron powder, stainless steel powder, graphite powder, etc. A method has been proposed in which the front and back steel plates easily come into contact with each other when pressure is applied by an electrode tip by forming irregularities on the steel plate to form a conductive circuit.

る。(Problems to be Solved by the Invention) Basically, it is possible to impart good welding performance to vibration-damping steel plates by using the above-mentioned means, but a detailed investigation of welding stability reveals that a single vibration-damping steel plate It has been confirmed that there are parts of the steel plate whose welding performance is as good as that of cold-rolled steel sheets, and parts where sparks are particularly likely to occur during welding, parts where the electrode tip welds, and in extreme cases, parts where it is impossible to conduct electricity. It was done. These welding defects are a phenomenon that occurs in only a small part of the material to be welded, but they can become a fatal problem in the automatic continuous welding process that is generally widely adopted.
The present invention advantageously solves this localized welding defect.

有益な技術を提示するものである。すなわち。(Summary of the invention to solve the problem) The first requirement for ensuring welding stability is the thickness of the resin, the size, shape, and addition ratio of the conductive material, and the uniformity and stability of the surface shape of the steel plate. , this can be handled within the scope of conventional technology. However, this alone may not be sufficient, and the present invention has been completed through research by the present inventors in this respect, and presents a new and useful technique. Namely.

冷却する際に生じる場合のある事も確認した。The inventors of the present invention have carefully investigated defective welding areas and investigated the causes thereof.
It was confirmed that welding defects occur in a surprising number of cases. This is caused by microscopic voids between the resin layer containing the conductive substance and the surface of the steel plate, and when a relatively high viscosity resin is used, or the size of the conductive substance is 0.05% of the resin film thickness. We found that such micro-voids are relatively likely to occur when the damping steel plate is heated to 180°C or less when the damping steel plate is heated to 180°C or less. It has also been confirmed that this may occur when cooling after applying a heat load such as heating for X2G.

鉛合金めっき鋼板の有利性は明白である。As a solution to this problem, it is effective to increase the affinity between the resin and the steel sheet surface. Specifically, it has been found that it is extremely important to improve the wetting properties of the resin during this time. Figure 0 shows the results of investigating the wettability between resin and various steel plates when polyester resin is used. Iron-zinc alloy plated steel plate (The sample shown in the figure is an iron-zinc alloy plated steel plate with an iron concentration of 12X) It can be seen that the wettability is good. The reason for this is that the surface of iron-zinc alloy plated steel sheets is relatively porous compared to cold-rolled steel sheets, galvanized steel sheets, etc., and the true surface area is larger than the apparent surface area. It seems to have gotten better. The advantages of iron-zinc alloy plated steel sheets are also evident in the welding stability test results shown later as examples.
本発明は、かかる見地から少なくとも制振性樹脂と接触
する２枚の鋼板面の片側に鉄−亜鉛合金めっき層を配置
することを基本にするものである。制振性樹脂と接する
２枚の鋼板表面が共に鉄−亜鉛合金めっきである事が最
も望ましいが。From this point of view, the present invention is based on disposing an iron-zinc alloy plating layer on at least one side of the surfaces of the two steel plates that come into contact with the damping resin. It is most desirable that the surfaces of the two steel plates in contact with the damping resin are both plated with iron-zinc alloy.

出来る。For example, even if iron-zinc alloy plating is applied only to one side and cold-rolled steel plate is applied to the other side, welding stability is significantly improved compared to a configuration in which both sides are made of only cold-rolled steel plates. The surface properties of the surface opposite to the surface in contact with the damping resin are not particularly specified in the present invention, but from the viewpoint of ease of manufacturing the iron-zinc alloy plated steel sheet, the same type of plating is applied to the front and back surfaces, or the surface that is in contact with the resin is plated with the same type. A single-sided plated steel plate in which iron-zinc alloy plating is applied only to one side and the other side has the surface of a cold-rolled steel plate can be advantageously applied.

なうめっき皮膜の部分的剥離現象が生じ易くなる等の不
具合を生じるので好ましくない。Regarding the plating layer composition of the iron-zinc alloy plated steel sheet applied in the present invention, the iron concentration is preferably 4 to 17%, and the iron concentration is 4%.
If the temperature is less than $1, the wettability with the damping resin will be almost the same as that of the cold rolled steel sheet, and the contact state between the resin and the steel sheet surface will be microscopically incomplete, which is undesirable because it will not satisfy the purpose of the present invention. In the iron concentration range of 18% to 30%, the contact between the resin and the steel plate is good, but there is no particular advantage to increasing the iron concentration to this range, and rather the phenomenon of partial peeling of the plating film that occurs during processing and forming. This is not preferable because it causes problems such as an increased likelihood of .

うものでない。It should be noted that the iron-zinc alloy plated steel sheet according to the present invention can be obtained by either a method of heat-treating molten zinc or a method of obtaining an iron-zinc alloy by electroplating, and almost the same good results can be obtained. The basics of the present invention are based on an iron-zinc alloy layer, but although the constituent components of this film are iron-zinc, they do not contain components intentionally or unavoidably mixed in with the prior art during the manufacturing process. For example, even if trace amounts or very small amounts of aluminum, magnesium, lead, tin, copper, etc. are contained, the effects of the present invention will not be impaired in the slightest.

る傾向にあり、好ましくない。Regarding the thickness of the damping resin layer, since the present invention relates to the contact interface between the resin and the steel plate, there is no direct relationship to the thickness of the resin, but welding performance is good when the thickness of the resin layer is 0.02 mm or less. However, the damping performance will suddenly decrease, and the thickness of the resin layer will be at the upper limit of 0.12 m.
If (2) is exceeded, even in the configuration of the present invention, blistering of the steel plate near the welded area due to thermal decomposition of the resin during welding tends to occur, and securing of the current-carrying circuit during welding tends to become unstable. , undesirable.

不利益が生じるものではないが、これ以上の厚みは実用
上無意味であり、経済上好ましくない。Considering the application of the product according to the present invention, the thickness of the steel plate used as the skin material of the damping steel plate should be 0.2 mm or more. If the skin thickness on one side is 0.21 mm or less, the welding itself will be stable. If the skin thickness is 1.5 mm or more, there will be no particular disadvantage in welding performance. However, a thickness greater than this is practically meaningless and economically undesirable.

的は十分達成する事が可能である。Although chromate treatment is preferable for the surface of the iron-zinc alloy plated steel sheet applied to the present invention in order to maintain adhesive strength over a long period of time, it is possible to sufficiently achieve the purpose of the present invention without chromate treatment. .
