本発明はスチールコード等の金網線条材との接着性が良
好なゴム組成物に関する。DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a rubber composition that has good adhesion to wire mesh wire materials such as steel cords.

Contains wire mesh wire material such as steel cord. On this occasion,
The strength and lifespan of the above rubber industrial products depend on the adhesion between the rubber material (whether natural or synthetic rubber) and the four-strand material such as steel cord.

ている。It is known that relatively high adhesive strength can be obtained by adding a certain type of cobalt compound, for example, it is known that the addition of a certain type of cobalt compound can provide a relatively high adhesive force in the rubber compound that can be used for the bonding part with the wire mesh to improve adhesion. U is already widely known.

ているものの。However, in these known techniques, the surface treatment of the wire mesh often requires a higher level of adhesion than the actual M1 standard and practical performance, making it extremely impractical. Although addition is widely adopted81.
ゴムを劣化させる作用が強いとい９欠点があり。It has 9 drawbacks: it has a strong effect on rubber deterioration.

影響が大きいき考えられる。To eliminate this drawback, expensive anti-aging agents are added. In addition, after heat aging, the adhesive strength between the rubber and the wire mesh deteriorates significantly, which poses a practical problem when considering the 2 to 3 additions and Ls in fJII (in the case of conveyor belts). Therefore, adhesive strength after high temperature and long-term aging is important for non-electronic products.
4. The adhesive strength has significantly decreased and there is no rubber adhesion around the steel cord, but when we measured the moisture content of this rubber, we found that it still contained around 1.0% multisheath moisture. Therefore, it is thought that moisture has a large effect on the adhesion between rubber and steel cord.
