Abstract


The accelerated aging tests of the special rubber were carried in laboratory. The tearing strength of the rubber in aging time was investigated. The rule of tearing strength and aging time was studied. The service life prediction function of the rubber was established and service life at 25℃ was estimated based on the index of tearing strength. The result shows that tearing strength of the rubber decreases in exponential form with aging time, and the service life of the rubber used in air at 25℃ is 35.79years.
