The invention discloses a high-pressure vulcanization process for rubber rollers, belonging to the field of rubber roller manufacturing. The specific operation steps are as follows: S1. Batching: placing raw rubber, Adhesive A, Adhesive S and fumed silica in equal proportions; S2. Mixing the raw materials, followed by internal mixing and filtration simultaneously; S3. Extruding and forming the rubber compound, then placing the molded rubber roller into a vulcanizing tank for vulcanization; S4. Introducing compressed air into the vulcanizing tank via an air pump, and adopting electric heating at the bottom inside the tank to raise the internal temperature. Electric heating wires are adopted for electric heating. Compressed air is delivered by an air pump to increase pressure. With elevated temperature and pressure, the vulcanization cycle is shortened. This process replaces the traditional procedures of nut tightening, polyester film wrapping, steam vulcanization, demolding and nut removal, greatly shortening the production cycle of rubber rollers.
