Abstract:
An adhesion accelerator for improving the bonding of vulcanized rubber to metal, in which the improvement is characterized in said adhesion accelerator comprising:at least one nickel organic compound selected from the group consisting of Ni-containing soaps having carboxylic acid moieties each having 6 to 30 carbon atoms in its main chain, or a mixture thereof, an organic boron complex containing Ni bonded to a carboxylic acid moiety having 6 to 30 carbon atoms in its main chain, and Ni-acetyl acetonate, and at least one zinc organic compound selected from the group consisting of Zn-containing soaps having carboxylic acid moieties each having 6 to 30 carbon atoms in its main chain, or a mixture thereof, an organic boron complex containing Zn bonded to a carboxylic acid moiety having 6 to 30 carbon atoms in its main chain, and Zn-acetyl acetonate, the at least one nickel organic compound and the at least one zinc organic compound being blended together to have a Ni/Zn weight ratio of from 0.01 to 20 in said adhesion accelerator.
