ADHESION PREVENTION METHOD OF INDIRECTLY VULCANIZED RUBBER PRODUCT

PURPOSE:To prevent oxidation so that a rubber product does not possess adhesion, by a method wherein after an ultra-accelerator has been applied to the surface of the unvulcanized rubber product, the same is vulcanized indirectly. CONSTITUTION:Although an ultra-accelerator 2 is an agent dissolved by...

Zusammenfassung:	PURPOSE:To prevent oxidation so that a rubber product does not possess adhesion, by a method wherein after an ultra-accelerator has been applied to the surface of the unvulcanized rubber product, the same is vulcanized indirectly. CONSTITUTION:Although an ultra-accelerator 2 is an agent dissolved by an appropriate solvent or water or an alcohol series solvent such as methanol or ethanol and applied to the surface 11 of an unvulcanized rubber product 1 with a brush or spray, the ultra-accelerator 2 is not infiltrated deeply into the unvulcanized rubber product 1 and a vulcanized rubber layer is formed only on the surface of the unvulcanized rubber product 1 at the initial stage of indirect vulcanization when the water which is non-dissolvable to the rubber or the alcohol series solvent such as the methanol or the ethanol is used as the solvent, deterioration can be prevented through supervulcanization of the rubber produce after indirect vulcanization. The ultra-accelerator 2 is desirably applied to the surface of the unvulcanized rubber product 1 as a 1-10% liquid solution.
