号公報）2. Description of the Related Art Conventionally, vulcanized rubbers are bonded to each other after mechanically buffing the surface of the vulcanized rubber or after treating the surface of the vulcanized rubber by a chemical treatment. Generally, a method of applying a paste or the like, superimposing an unvulcanized rubber thereon, and performing vulcanization bonding is generally used. Other bonding methods have been proposed.
As described in Japanese Patent Publication No. 27534 (JP-B-7-21064),
A method in which a highly polar phenolic resin or the like is previously blended when vulcanized rubber is produced is used as a vulcanized rubber, and a method using a two-part special adhesive is also proposed. Furthermore, as proposed by the present inventors,
Proposes a method of vulcanizing with a sheet-like material that has irregularities on at least one side and is easy to peel off from the vulcanized rubber, without buffing, etc. doing. (Japanese Unexamined Patent Publication No. 8-176314)

題点も多い。[0003] However, in the case of the former general method, a rubber having a low polarity (NR, SBR, etc.) cannot easily obtain satisfactory adhesive strength at room temperature, and vulcanization adhesion by heat is essential. Since it requires equipment such as a vulcanizing press and a mold, it is expensive, and there are many other problems such as difficulty in on-site work. Further, in the latter proposal, since an elastomer mainly composed of a component such as a sulfur-vulcanizable phenolic resin is preliminarily compounded in the vulcanized rubber, the adhesiveness is improved as compared with the former, but it is not necessarily required. There are many problems such as deterioration of the original rubber properties to be performed and complicated work processes.

As described above, the surface of the unvulcanized rubber before vulcanization at least in a portion where the vulcanized rubbers are to be bonded to each other in advance at least on one side has irregularities on at least one surface, and is easily peeled off from the rubber after vulcanization. Vulcanize after inserting the shape. Then, by peeling off the sheet-like material immediately before bonding, the vulcanized rubber surface can be provided with appropriate irregularities suitable for bonding, and the surface can have a fresh (bleedless) surface. Proposal by Japanese Patent Laid-Open No. 8-17631
The present invention is applied to a sheet-like material such as canvas, which is previously coated with a chloroprene-based rubber on the surface, inserted into an adhesive portion, vulcanized, and adhered. When peeled immediately before, the highly polar chloroprene-based rubber adheres to the rubber surface, enabling good room-temperature bonding via a strongly polar resin-based or rubber-based adhesive, particularly preferably a chloroprene-based adhesive. It is what becomes. Therefore, the physical properties of the rubber itself are not affected.
