本発明は2枚の金属板をスポット溶接するにあたって金

ール材を塗らねばならなかった。Conventionally, when spot welding two metal plates, self-fusing butyl rubber tape, adhesive, sealant, etc. have been used to make the welded part waterproof, anticorrosive, and vibration proof. In this case, if these sealants were present in the parts of the two metal plates to be spot welded, welding would be impossible due to the insulating properties of the sealants. Therefore, it was necessary to perform welding at different locations between the seals and welds, or to apply sealants after welding.

う欠点がある。When pressure is applied perpendicularly to the sheet surface of this pressure-sensitive conductive sheet material, a rapid drop in electrical resistance occurs due to the contact action of the blended metal particles. Therefore, a sheet is inserted as a sealing material at the welding point of two metal plates to be spot welded, and the sheet is inserted from the top of the metal plates.
Spot welding can be performed through this seal material. That is, during spot welding, pressure is applied to the sealing material sandwiched between two metal plates through the metal plates by the cylinder pressure of the spot welding machine, resulting in a sudden drop in resistance. As a result, a current flows between the two metal slopes, making spot welding possible. However, in the case of a sheet containing pure metal or metal alloy particles, the metal particles on the surface will rust, impairing the electrical conductivity of the sheet, corroding the sealed metal plate, and changing the appearance. It has the disadvantage of impairing the

。On the other hand, it is also desired that the sealing material for spot welding has vibration damping properties. This damping property has the effect of attenuating and muffling the vibrations and noise of metal plates, etc. Conventionally, this type of damping material uses a composition made of a rubber or plastic polymer mixed with an inorganic filler, etc., but the damping effect of these damping material compositions depends on the polymer itself. Since the loss coefficient was small, even if the amount of filler was increased, the damping effect did not improve much. There was also a limit to the amount of filler added. On the other hand, as mentioned above, in products containing metal particles, there is a problem with the compatibility between the metal and the rubber-like elastic body, in addition to correcting rust as described above, and it is difficult to obtain uniform dispersion of the metal particles. There was a risk that variations would occur in the damping effect of the sheet material. Furthermore, high filling of metal particles softens the rubber-like elastic body, making it extremely difficult to process the sheet and at the same time making it difficult to obtain sufficient elasticity. The present invention solves these problems at once, and is characterized by using metal silicon alloy fine powder instead of metal particles.
即ち、金属ケイ素合金粉末を用いるときは金属のように

う欠点は克服される。That is, when a metal silicon alloy powder is used, unlike metal, it does not rust, so the above-mentioned drawbacks associated with the formation of rust can be overcome.

る。本発明における制振性スポット溶接用シール材は見
掛け比重が大きく、好ましくは2.5以上であるので薄
いシート状のものでも大きな損失係数を持っているため
息い制振効果を発揮できる。Further, since metal alloys have an affinity for rubber-like elastic bodies, high filling (high density packing) is possible, and uniform dispersion can be obtained. Therefore, it is possible to overcome the drawbacks of using conventional inorganic fillers and metal powders, and to create a sheet that has a large apparent specific gravity and does not impair the desired elasticity of the rubber-like elastic body, which is difficult to process. There is also the advantage that it can be manufactured without The vibration-damping spot welding seal material of the present invention has a large apparent specific gravity, preferably 2.5 or more, so that even a thin sheet-like material can exhibit a damping vibration damping effect with a large loss coefficient.

うにするのが望ましい。The loss factor of the rubber compounded composition used in the present invention increases as the filling amount of metal silicon alloy particles increases, but when increasing the apparent specific gravity, the rubber sheet material is not damaged compared to the rubbery elastic body. It is desirable to select the amount, type of metal silicon alloy particles, and particle size of metal silicon alloy particles depending on the application. However, usually, metal silicon alloy particles of 15 to 2000 µm containing at least 5% of silicon are blended in an amount of 2 to 70% to the rubber-like elastic body, and the apparent specific gravity of the resulting rubber composition is 2.5. It is desirable to have the above.
