No. 584 discloses that a sheet-shaped damping material (damping resin) is inserted into the hollow of an extruded aluminum material, and the damping material sheet is subjected to heat treatment of aluminum (aging treatment at 200 ° C. or lower).
An aluminum vibration damping member obtained by heat-sealing to a face plate and / or a rib by using the above method is described. Further, it is described that, for example, a modified asphalt-based resin, butyl rubber-based special synthetic rubber, or the like is used as the vibration damping resin.
As shown in FIG. 7, the above publication discloses a vibration damping type in which a vibration damping material sheet 2 is heat-sealed to the inner surface of a face plate below a profile 1 composed of two face plates and truss-shaped ribs and the upper surface of the ribs. A material (a) and a vibration-damping material (b) obtained by thermally fusing a vibration-damping material sheet 2 to the inner surface of a face plate of a solid profile 1 are described.

In some cases, it is desired to heat-bond the sheet.
The surface on which the vibration damping material sheet 2 can be placed by its own weight is limited, and therefore it is impossible to apply the vibration damping material sheet 2 to all the desired surfaces and perform heat fusion at once. Therefore,
In this case, as shown in FIG. 8, in FIG. 8A, after damping material sheet 2a is first heat-sealed to the inside of one face plate, the profile 1 is turned over, and the inside of the other face plate and the rib Damping material sheet 2
Take the procedure of heat-sealing with placing b. In (b),
After heat-sealing the damping material sheet 2a to one surface of the rib and part of the face plate first, the profile 1 is inclined in the opposite direction, and the other surface (back surface) of the rib and the remaining portion of the face plate are attached. Damping material sheet 2b
It is necessary to take the procedure of carrying out heat fusion with mounting.

As shown in FIG. 8, the resin melts again, and the resin is dropped or peeled off by gravity. Therefore, two opposite surfaces of the profile 1 (the inner surfaces of the upper and lower face plates in the above example (a)) or 1 It was not possible to thermally fuse the damping material sheet to both one surface and the back surface (both surfaces of the rib in the above example (b)). Of course,
Although it is possible to apply resin to the facing surface and the front and back surfaces by painting, compared to the heat fusion method, the thickness of the vibration damping material is not uniform and the quality is not stable. In many cases, it cannot be applied to the inner surface.

製造方法を目的とする。As described above, when the vibration damping material sheet is heat-sealed to the profile, the surface to be heat-sealed is limited to the surface on which the vibration damping material sheet can be placed by its own weight. When the attachment is performed, there is a problem such as peeling due to re-melting of the damping material sheet that has been previously heat-sealed, so that the surface on which the damping material sheet is heat-sealed is restricted (for example, two opposite faces of the shaped material). However, there was a problem that sufficient vibration damping performance could not be expected in some cases. The present invention has been made in view of the above-described conventional problems, and a method of manufacturing a vibration-damping shape material in which a surface of a shaped material to be thermally fused to a vibration-damping material sheet is not restricted as described above.

First, FIG. 1 shows two types of damping material sheets 12a having different melting temperatures on the inner wall surface of, for example, a long extruded aluminum material 11 having a mouth-shaped cross section (in other words, two sets of two opposing surfaces). , 12b are shown. At this time, as the damping material sheet, a sheet made of a damping resin alone or a composite sheet made of a damping resin layer and a hot melt film layer can be used. For example, two types of damping resins having different melting temperatures can be used. Combination of single sheets, combination of damping resin single sheet (damping material sheet with high melting temperature) and composite sheet (low melting temperature damping material sheet), combination of damping resin single sheet (damping material sheet with low melting temperature) ) And a composite sheet (a damping material sheet having a high melting temperature), a composite sheet having a hot melt film layer having a different melting temperature, and the like.

May be of a type requiring aging treatment, this heating may also serve as aging treatment. Once cooled, the extruded profile 11 is inverted as shown in FIG.
The vibration damping material sheet 12b on the low melting temperature side is inserted into the hollow interior of the extruded profile 11, placed on the remaining two surfaces, and heated and thermally fused. The heating temperature at this time is set to be lower than the melting temperature of the damping material sheet 12a on the high melting temperature side that has been previously heat-sealed, so that the damping material sheet 12a is re-melted and the resin does not drip or peel off.

Facing 2
However, as described above, by performing the two-stage heat fusion treatment using the damping material sheets having different melting temperatures as described above, all the faces of the mouth-shaped cross section (opposite faces) were obtained. (There are two sets of two surfaces to be bonded). Further, it is needless to say that this method can be applied to a profile having another shape, for example, a profile having two face plates and a truss-type rib or a solid profile as shown in FIG. On the other hand, the damping material sheet 2a to be thermally fused first is used as the vibration damping material sheet on the high melting temperature side, and the damping material sheet 2b to be thermally fused next is used as the vibration damping material sheet on the low melting temperature side. By doing so, the intended purpose can be achieved. In addition, it is also possible to prepare three or more types of damping material sheets having different melting temperatures, and to perform the heat fusion process in three or more stages.

小さくすることができる。FIG. 2 shows a procedure in which a damping material sheet is placed on at least one surface of a plate or a shape, heated, thermally fused, and then bent to obtain a desired shape of the damping material. According to this method, according to this method, a vibration-damping shape material in which a vibration-damping material sheet is heat-fused to two opposing surfaces, which was conventionally impossible to manufacture, or almost the entire inner peripheral surface is damped. Even a vibration damping material obtained by heat-sealing a vibration material sheet can be easily manufactured. If a section having a cross section close to the final target shape is formed in advance and the damping material sheet is heat-sealed to this, the degree of bending after the heat-sealing of the damping material sheet is reduced, and The bending radius at the corner can be reduced.

制振特性の優れた制振形材を得ることができる。According to the present invention, the surface on which the shaped vibration damping material sheet is to be heat-sealed is not restricted as in the prior art. For example, two opposing surfaces or one surface and the back surface thereof may be used. As described above, it is possible to obtain a vibration-damping shape material in which the vibration-damping material sheet is heat-fused to the surface where the conventional vibration-damping material sheet could not be heat-sealed,
It is possible to obtain a damping shape member having excellent damping characteristics.
