Abstract

PURPOSE: To provide a vulcanized rubber with a low-friction skin layer of controlled thickness, without lowering its original characteristics, and to widen the application range of the rubber, by treating a vulcanized rubber first with an organic acid and then with a hypohalogenite.
CONSTITUTION: (A) A vulcanized rubber (e.g. provided by compounding a natural or synthetic rubber with a conventional vulcanizing agent and additives) is pretreated with (B) an organic acid (e.g. acetic acid, etc.) and then dipped in (C) an aqueous solution of a hypohalogenite (e.g. sodium hypochlorite, etc.) or a mixture of a hypohalogenite and acetic acid, to give the surface-treated vulcanized rubber. The concentration of the component (B) is 0.1W100% and the treatment is carried out at room temperatures for 1min. to 24hr. The concentration of the component (C) is preferably 0.05W5% as effective halogen.
EFFECT: Free from formation of cracks.
