Abstract
A method of increasing the adhesion of a rubber (as hereinbefore defined) or rubber-based material which includes treating at least part of the surface of the rubber or rubber-based material with a halogenating agent simultaneously with a static and/or high freguency alternating physical field.
Claims11
A method for increasing the bonding capability of solid vulcanized rubber material with other materials, which method comprises the steps of:
- (i) treating at least part of a surface of said solid vulcanized rubber material with a halogenating agent while simultaneously subjecting said surface to a static and/or high frequency physical field to provide a halogenated surface;
- and
- (ii) treating the halogenated surface with at least one coupling agent.
A method for increasing the bonding capability of solid vulcanized rubber material with other materials, which method comprises the steps of:
- (i) treating at least part of a surface of said solid vulcanized rubber material with a halogenating agent while simultaneously subjecting said surface to heat in a range of from 30.degree. C. to 100.degree. C. to provide a solid vulcanized rubber material having a halogenated surface;
- and
- (ii) treating the halogenated surface with at least one coupling agent.
