摘要： A process for producing an aging-resistant rubber material, in which even when a rubber layer has been formed from an aqueous rubber latex, the heat resistance thereof can be improved without impairing its moldability. Even when an antiblocking treatment with an antiblocking agent is conducted, this does not lead to a cost increase. The process comprises applying a coating fluid containing an amine aging inhibitor dissolved or dispersed therein to a surface of a crosslinked rubber material and then heating the rubber material to 80°C or higher to diffuse the amine aging inhibitor thereinto and thereby produce an aging-resistant rubber material. When the coating fluid is one which contains an antiblocking agent dissolved or dispersed therein besides the amine aging inhibitor, then the crosslinked rubber material as a product simultaneously undergoes an antiblocking treatment.
