Abstract

PROBLEM TO BE SOLVED: To provide a laminated rubber structure comprising rubber and a hard printing plate in which strong adhesion is made possible without using an adhesive, processes of surface treatment and others are reduced remarkably in adhesion to facilitate the production, and peeling between interfaces of the rubber and the hard printing plate is prevented even in contact with metal, saline water, and others. SOLUTION: In a laminated rubber structure comprising rubber and a hard printing plate, by using a material selected from the combination of specified rubber with specified plastic, such as specified rubber with polyhphenylene ether and specified rubber copolymerized with an acid component with a polyamide, since no adhesive is used, a treatment process such as blasting and priming is not required.

Field of the Invention The present invention relates to a laminated rubber structure, and more particularly to an improvement in a laminated rubber structure used as a seismic isolation rubber for a building, a seismic isolation rubber for a bridge, a rubber bearing, and the like.

Description of the Related Art As a seismic isolation rubber or rubber bearing for a large-scale structure such as a building or a bridge, a laminated rubber structure composed of (A) rubber and (B) hard plate as shown in FIG. 1 is used. ing. Of these, metals have been used exclusively as hard plates.

積層後、加硫接着を行なう。Conventionally, in such a laminated rubber, when bonding the rubber and the hard plate, it is necessary to perform a base treatment on the bonding surface of the hard plate. As the base treatment method, a normal hard plate, especially a metal surface is provided by blasting with a shot, a grid, sand, or the like, or polishing with a sandpaper, a wire brush, or the like, and surface irregularities that induce an anchor effect are imparted. The method is generally followed by the application of an adhesive to the adhesive surface, commonly referred to as the primer, the application of an agent that facilitates fixing, followed by the application of a one- or two-part adhesive, followed by rubber After lamination, vulcanization bonding is performed.

Long-term reliability is required.

い、といった問題を生じる。[0005] However, in the conventional laminated rubber structure in which the rubber and the hard plate are bonded after the base treatment by blasting or polishing and the primer treatment as described above, the process is complicated, and it is difficult to perform sufficient process inspection. Therefore, not only a structure satisfying sufficient reliability may not be obtained, but also the overall manufacturing cost may be increased due to complicated processes. In addition, due to insufficient bonding, if left in a high-humidity environment for a long period of time, peeling between the rubber and the hard plate gradually occurs and occurs. Such a situation causes a great deal of damage to the laminated rubber structure, and eventually causes a problem that the original life and performance cannot be satisfied.

積層ゴム構造体では満足な信頼性を得る事はできない。[0006] In particular, when the hard plate is made of metal, if the steel material as the metal plate is in contact with a dissimilar metal such as zinc, or if the environment in which the laminated rubber structure is used is exposed to salt water or the like, the peeling may occur. The traveling speed is accelerated. Therefore, they are often used in sea or coastal cities, and the parts to which they are attached are subjected to anticorrosion treatment such as galvanization, or the seismic isolation rubber for bridges, or the upper and lower flanges of the laminated rubber structure are made of zinc. For bridge-isolated rubber for bridges to be plated, it can be said that the bonding environment is quite harsh, but satisfactory reliability cannot be obtained with the conventional laminated rubber structure.

These rubbers are subjected to the following steps: a) contacting a hard plate made of polyphenylene ether and its composition in an unvulcanized state, followed by heat vulcanization to form a strong bond with the hard plate. It is simple. The mechanism of this adhesion is that, if the rubber has a styrene segment, the styrene segment is diffused to a) polyphenylene ether and its composition side,
Otherwise, the peroxide used as the vulcanizing agent results in the formation of a chemical bond between the rubber and a) the polyphenylene ether and its composition. Therefore, the rubber that can be used at this time is exemplified by the rubbers described above, but is not necessarily limited thereto. Rubbers having a styrene segment or rubbers that can be favorably vulcanized by a peroxide are used. If so, it does not matter in principle.
From the bonding mechanism described above, as a vulcanization method that can be used, peroxide vulcanization or sulfur vulcanization for rubber having a styrene segment, and peroxide vulcanization for rubber having no styrene segment. Can be mentioned.
