Title:
耐老化性ゴム材料の製造法
Document Type and Number:
Japanese Patent JP4127033
Kind Code:
B2
Abstract:
An aging-resistant rubber material with an improved heat resistance without deteriorating the moldability even if a rubber layer is formed from an aqueous latex of rubber and without any cost increase, even if a surface tack prevention treatment by an antitack agent is carried out, can be produced by applying a coating liquid containing an amine-based antioxidant in solution or dispersion to the surface of a cross-linked rubber material, followed by heating to a temperature of 80 DEG C or higher, thereby diffusing the amine-based antioxidant into the rubber material. When a coating solution containing an antitack agent together with the amine-based antioxidant in solution or dispersion is used, the surface tack prevention treatment of the cross-linked material as a product can be made at the same time.
