More specifically, it relates to a rubber composition that can improve the adhesion between metal cords, particularly steel cords, and filling rubber for steel cords in the belt and carcass parts of radial tires, rubber for filling steel cords in conveyor belts, etc. It is something.
（従来の技術）

初期に安定した接着を得る接着技術は、加硫に対する接
着の安定性を増し、加硫時間の短縮を可能にするために
加硫生産性、省エネルギー性の観点からその必要性が高
まってきている。(Conventional technology) Adhesion technology that increases the adhesion speed between metal cord and rubber to obtain stable adhesion in the early stage of vulcanization increases the stability of adhesion during vulcanization and shortens vulcanization time. The need for this is increasing from the viewpoints of vulcanization productivity and energy saving.

等の手段を採ればよいことが経験的に知られている。Conventionally, in order to increase the adhesion speed between the metal cord and rubber, a) the Cu content of the positive plating composition of the metal cord was increased (
1) Increase the amount of organic cobalt compound as an adhesion promoter, 3) Use diketone cobalt as the organic cobalt compound, 2) Increase the basicity of the vulcanization accelerator. known from experience.

A technique for incorporating ~20 aliphatic saturated-hydric alcohols into a steel cord coated rubber composition is disclosed.
（発明が解決しようとする課Ｂ）
しかし、従来の接着技術は必ずしも満足のいくものでは
なかった。(Problem B to be solved by the invention) However, conventional adhesive techniques were not always satisfactory.
すなわち、先ず上記イ）の如く金属コードのプラスめっ
き組成のＣｕ含有量を多くすると金属コード表面の活性
が増すため、接着に対する未加硫ゴムおよび金属コード
の放置安定性が著しく低下し、工場生産に適さなくなる
。また、上記二）の如く加硫促進剤の塩基性を増した場
合にも、未加硫ゴム放置により加硫促進剤が分解し易く
なり、上記と同様の理由により好ましくない。That is, first of all, as mentioned in (a) above, increasing the Cu content in the positive plating composition of the metal cord increases the activity of the metal cord surface, which significantly reduces the storage stability of the unvulcanized rubber and metal cord for adhesion, and reduces factory production. becomes unsuitable for Furthermore, even when the basicity of the vulcanization accelerator is increased as in 2) above, the vulcanization accelerator tends to decompose when the unvulcanized rubber is left, which is not preferred for the same reason as above.
次に上記口）の如く有機コバルト化合物を増量すると、
ゴムの耐熱老化性が著しく低下し、また配合コストが上
昇することにより実用に適さなくなる。Next, if the amount of organic cobalt compound is increased as in the above example,
The heat aging resistance of the rubber is significantly reduced and the compounding cost increases, making it unsuitable for practical use.
上述の如く、上記イ）１口）および二）の接着技術によ

った。これに対し、上記ハ）の如く有機コバルト化合物
としてジケトン系コバルトを使用する接・着技術におい
ては接着速度の大幅な上昇が認められた。しかし、同時
に加硫初期の加硫速度も大幅に上昇するため焦げ易くな
り、工場での加工性を低下させるという問題が生じた。As mentioned above, the advantage of increasing the adhesion speed obtained by the adhesion techniques 1) and 2) above was not sufficient. On the other hand, in the bonding technology using diketone cobalt as the organic cobalt compound as in c) above, a significant increase in the bonding speed was observed. However, at the same time, the vulcanization rate at the initial stage of vulcanization also increases significantly, making it easier to burn, resulting in a problem of lowering workability in the factory.
上記特開昭６３−２０３４５号公報記載の所定のアルコ
ール類を配合する技術においても、初期接着速度および
初期加硫速度の両者点で十分なものとはいえなかった。Even in the technique of blending a predetermined alcohol described in the above-mentioned Japanese Patent Application Laid-open No. 63-20345, it could not be said to be sufficient in terms of both initial adhesion speed and initial vulcanization speed.
そこで本発明の目的は、金属コード・ゴム複合体におい
て金属コードとゴムとの間の接着速度を上昇させて加硫
の初期に安定した接着を得る一方、加硫初期の加硫速度
を上昇させることのないゴム組成物を提供することにあ
る。Therefore, the purpose of the present invention is to increase the adhesion speed between the metal cord and rubber in a metal cord/rubber composite to obtain stable adhesion at the initial stage of vulcanization, while increasing the vulcanization speed at the initial stage of vulcanization. The purpose of this invention is to provide a rubber composition that is completely free of defects.

るに至った。(Means for Solving the Problems) As a result of intensive studies by the present inventors to solve the above problems,
By blending a predetermined amount of an organometallic cobalt compound and an aliphatic polyhydric alcohol into a rubber composition of diene rubber, it is possible to increase the adhesion speed while suppressing the increase in the vulcanization speed at the initial stage of vulcanization. This finding led to the completion of the present invention.

着性の著しい低下を招くことになる。(Function) The organometallic cobalt compound used in the present invention is 0.00% in terms of cobalt metal amount per 100 parts by weight of the rubber component.
If the amount is less than 0.2 parts by weight, sufficient adhesion with the cord cannot be obtained, while if it exceeds 1 part by weight, the heat-resistant adhesion between the rubber and the cord will be significantly reduced.

しく、好ましくない。In addition, in the present invention, the addition of aliphatic polyhydric alcohols does not increase the initial vulcanization rate (initial adhesion can be improved, but the addition amount is 5 parts by weight per 100 parts by weight of the rubber component). If it exceeds this, the breaking strength of the rubber will drop significantly, which is not preferable.

上昇を抑えることができる。(Effect of the invention) As is clear from Table 1 above, the metal cord of the present invention
In a rubber composition for a rubber composite, it is possible to increase the adhesion rate between the metal cord and the rubber while suppressing an increase in the vulcanization rate at the initial stage of vulcanization.
この結果、加硫に対する接着の安定性が増し、加硫時間
