The invention belongs to the technical field of manufacturing of sealing rubber rings, and particularly relates to an anti-aging rubber material for sealing and a manufacturing process thereof, wherein the interior of an extrusion ring is arranged in a hollow manner, and extrusion pipes are uniformly inserted and installed in the extrusion ring; an air pressure hole is formed in the middle wall of the extrusion pipe, and pushing rods are elastically connected inside two ends of the extrusion pipe through springs; the upper outer surface and the lower outer surface of the two ends of the push rod are hinged with elastic push rods; the outer end of the elastic push rod is hinged to the outer surface of the extrusion plate; the extrusion plate is obliquely and fixedly arranged in the wall of the body; the invention mainly aims to solve the problems that in the prior art, the rubber gasket used in the oil cylinder is difficult to select and can contact corrosive media such as gasoline, diesel oil, engine oil and the like, so that the rubber used for the oil cylinder sealing gasket has good oil resistance, corrosion resistance and the like, but the rubber in the existing market often cannot meet the requirements, so that the sealing effect is poor and the leakage phenomenon is easy to occur. |
