る。 As described above, the vibration damping material having the above-mentioned structure is being adopted in various technical fields due to its excellent vibration damping performance. However, the layer made of a polymer viscoelastic material is used. Since it is electrically insulating, resistance welding cannot be performed, and there is a problem that the application is limited. Therefore, for the purpose of imparting conductivity to the polymer viscoelastic material, an attempt was made to disperse and mix the metal powder, but it is difficult to fill a large amount of metal powder on the process, conductivity is not obtained , The problem has not been resolved. Even if a large amount of metal powder can be filled and conductivity is obtained, on the other hand, the vibration damping performance is deteriorated. Also,

接が不可能となる。In the present invention, the conductive carbon black and the metal powder are used together for the following reason. When metal powder is blended singly, for example, in rubber, the amount of blending is limited due to the problem of rubber processability. The metal powder does not exist in the form of a mesh while the powders are in contact with each other in the rubber, but the metal powder exists individually or in the form of a chain-like, mesh-like or lump-like aggregate surrounded by the rubber matrix. Since this rubber matrix is electrically insulating, the resistance becomes large and welding becomes impossible.

急激に大量に分解し、爆発等の不具合が生じる。On the other hand, when the conductive carbon black alone is compounded in the rubber, the volume resistivity of the rubber is 1000.
It can be about 0.1 Ω · cm . However, welding is impossible with this resistance value. Therefore, it is necessary to apply a large current to the rubber layer to break it and bring the metal plates into contact with each other. At this time, if the rubber layer is thick, a larger current is required. When the rubber is destroyed, the metal plates come into contact with each other and a large current flows, so that heat generation is increased, the rubber is rapidly decomposed in a large amount, and problems such as explosion occur.

バラツキが小さくなる。 However, when the metal powder and the conductive carbon black are used in combination, the rubber matrix surrounding the metal powder is conductive and the layer is thin, so that the rubber is easily destroyed at a low current, Since the two metal plates come into contact with the metal powder and the diameter of the current can be passed, welding becomes possible. In this case, since the current is small, the heat generation is small, and the above-mentioned problems do not occur. Also conductive rubber matrix
By changing the conductivity, the electric current can be applied not only in the thickness direction but also in the lateral direction.
Since the current flows in all directions such as the
Of the welding strength

For example, in the case of a rubber viscoelastic material, 10 to 150 PHR is preferable. Below 10 PHR, the electrical conductivity is low, so it becomes difficult for the current to break the rubber to flow.
If it is above, the workability of the rubber is significantly lowered. The amount of the metal powder blended is preferably 250 to 1500 PHR. 250 PH
Below R, the layer of the rubber matrix surrounding the metal powder becomes thick and welding cannot be performed. When it is 1500 PHR or more, problems such as deterioration of rubber workability occur.

す。In the vibration damping materials shown in the three structural examples above, a large amount of conductive filler can be blended as compared with the conventional constrained vibration damping material, so that stable welding strength can be obtained by resistance welding. To be In addition, compared to the conventional damping material, since the filler is blended in a larger amount, the peak value of the loss coefficient decreases, but the loss coefficient in the high temperature range is larger than that of the conventional material, and the wide temperature range. A vibration damping material having good vibration damping performance in the range can be obtained. In addition, as shown in FIGS. 1 and 2, in the case where a metal viscoelastic layer is preliminarily formed on a metal plate as a material, it can be manufactured inexpensively in a conventional damping material manufacturing process.
Moreover, there is an advantage that it can be manufactured with mass productivity. Next, specific examples mainly containing the compound used for the polymer viscoelastic material will be shown.
