Claims19
A rubber product which is comprised of an elastomeric material having a flexible aramid fiber cord embedded therein, wherein the flexible aramid fiber cord is made by a method consisting of the sequential steps of:
- (1) heating the flexible aramid fiber cord, (2) dipping the aramid fiber cord into a liquid composition which consists of:
- (i) a liquid epoxy resin selected from the group consisting of a bisphenol-A-based liquid epoxy resin, a bisphenol-F-based liquid epoxy resin and combinations thereof;
- (ii) 2-ethylhexyl glycidyl ether;
- and (iii) at least one curing agent, (3) removing any excess liquid composition from the flexible treated cord, and (4) drying the flexible treated aramid fiber cord, wherein the treated aramid fiber cord is flexible enough to be used as a reinforcement in rubber-based products including power transmission belts, hoses, and conveyor belts.
