Technology) Reducing the vibrations and noise generated by automobiles, ships, structures, etc. is a very important issue in increasing their commercial value. Conventionally, vibration and noise have been reduced by reducing the rigidity of the vehicle or by adding mass to move the resonance frequency out of the frequency range of interest. However, with this h-method, the object tends to become heavier or larger6.Nowadays, weight reduction and miniaturization are important points in design, so Techniques such as using materials with high vibration damping performance or adhering a damping sheet made of viscoelastic material have been taken.

A restrained type composite laminated layer with excellent vibration damping properties, which is characterized by laminating the sheet-shaped resin between thick steel plates (at a temperature below the melting point of the fat) and then heating the whole in a heating furnace to a temperature above the melting point of the resin. In the manufacturing method of steel plates and the manufacturing method of restrained composite laminated thick steel plates with excellent vibration damping properties in which foamed resin is laminated on thick steel plates, foamed resin is formed into a sheet shape, and the sheet-like resin is placed between the thick steel plates. A constrained composite with excellent vibration damping properties, which is characterized by laminating layers at a temperature below the melting point of the resin, then heating the whole in a heating furnace below the melting point of the resin, extracting it from the heating furnace, and then lightly rolling it down with a roll or press. This is a manufacturing method for laminated thick steel plates.

０本発明は後者の拘束型を対象とする。(Function) The damping material effectively exhibits its function through a combination of a viscoelastic body and a constraining layer. The constraining layer not only achieves electromagnetic properties, but also helps to improve the vibration damping properties of the viscoelastic body.The non-constraint type, in which the gunbing sheet is bonded to the steel plate, causes bending deformation in the direction of the tensile force of the viscoelastic body. The restraint type sandwiched between steel plates absorbs vibration energy through shear deformation and consumes it as heat.The present invention is directed to the latter restraint type.

より、制振性のみならず吸音性、断熱性にも優れる。Foamed resin contains a large number of bubbles in the resin, and compared to ordinary resin, it has excellent not only vibration damping properties but also sound absorption and heat insulation properties due to the energy absorption of air molecules within the bubbles.

In addition, in the present invention, there are many thermoplastic resins and thermosetting resins including polyolefin resins, polystyrene resins, and polyurethane resins.
Any commercially available foamed II fat can be selected depending on the intended use. By molding these foamed resins into sheets and laminating them and bonding them together, construction efficiency can be greatly improved compared to the conventional method of bonding gunbing sheets after building a structure.

しい。The adhesion between the steel plate and the foamed resin is due to the fusion of the resin, and therefore it is necessary to heat the adhesion interface to a temperature higher than the melting point of the resin. As for the heating method, it is preferable to charge the laminated composite steel sheets into a thermal furnace after lamination to ensure homogeneous adhesion over the entire laminated composite steel plate, and hold the whole at a temperature above the melting point of the material for about 5 to 60 minutes. There is no particular limit to the upper limit of the heating temperature, but there is a natural limit as high temperatures may cause the resin to flow, bubbles in the resin may collapse, and the resin itself may decompose. In practice,
It is preferable to heat the resin to a temperature equal to or lower than the melting point of the resin +100°C.
なお、接着強度については、鋼板自重によるプレス効果

えない。As for the adhesive strength, the adhesive strength is sufficient just by fusion due to the pressing effect of the steel plate's own weight, but there is no problem even if the roll rim is lightly reduced in a press after being extracted from the heating furnace.
