Abstract

A rubber-metal adhesion promoter characterized by including a compound (1) represented by the following general formula (A): (in the formula, Z represents a structure selected from the following formulae (z-1) to (z-4); M represents titanium or zirconium; and (RCOO) represents a residue of an aliphatic carboxylic acid having 2 to 25 carbon atoms)

First claim

The invention claimed is:

1. A rubber-metal adhesion promoter comprising a compound (1) represented by the following general formula (A):
[(RCOO) 3 MO] 3 Z  (A)

wherein Z represents a structure selected from the following formulae (z-1) to (z-4);

M represents titanium; and (RCOO) represents a residue of an aliphatic carboxylic acid having 2 to 25 carbon atoms.

2. The rubber-metal adhesion promoter according to claim 1 , wherein said Z is a structure represented by said formula (z-1).

3. The rubber-metal adhesion promoter according to claim 2 , wherein said (RCOO) is a residue of 2-ethylhexanoic acid, a residue of neodecanoic acid, a residue of hexadecanoic acid or a residue of octadecanoic acid.

4. A rubber composition comprising:
the rubber-metal adhesion promoter according to claim 3 ; and
a rubber component.

5. A rubber composition comprising:
the rubber-metal adhesion promoter according to claim 2 ; and
a rubber component.

6. The rubber composition according to claim 5 , which contains 1 to 7 parts by mass of said rubber-metal adhesion promoter with respect to 100 parts by mass of said rubber component.

7. A tire comprising a steel cord/rubber composite including the rubber composition according to claim 5 and a steel cord.

8. The rubber-metal adhesion promoter according to claim 1 , wherein said (RCOO) is a residue of a saturated aliphatic monocarboxylic acid having 2 to 20 carbon atoms.

9. A rubber composition comprising:
the rubber-metal adhesion promoter according to claim 8 ; and
a rubber component.

10. The rubber composition according to claim 9 , which contains 1 to 7 parts by mass of said rubber-metal adhesion promoter with respect to 100 parts by mass of said rubber component.

11. A tire comprising a steel cord/rubber composite including the rubber composition according to claim 9 and a steel cord.

12. The rubber-metal adhesion promoter according to claim 1 , which is used for adhering rubber and a steel cord.

13. A rubber composition comprising:
the rubber-metal adhesion promoter according to claim 12 ; and
a rubber component.

14. A rubber composition comprising:
the rubber-metal adhesion promoter according to claim 1 ; and
a rubber component.

15. The rubber composition according to claim 14 , which contains 1 to 7 parts by mass of said rubber-metal adhesion promoter with respect to 100 parts by mass of said rubber component.

16. A tire comprising a steel cord/rubber composite including the rubber composition according to claim 14 and a steel cord.
