| Abstract: |
| The effects of damp heat salt spray environment on the aging properties of silicone rubber
（methyl vinyl silicone rubber）were explored through the aging test of silicone rubber in hot air（air），pure
water（water），artificial seawater（seawater），damp heat and damp heat salt spray environments. The results
showed that when the silicone rubber was aged without stress，the effects of water（steam） on the tensile
strength and elongation at break were not obvious. When aging under compressive stress，the effect of water
（steam） on the compression set was significant. The accelerated aging effect of salt spray on silicone rubber
was not obvious，and compared with the test results of aging in air，the accelerated aging effect of damp heat
salt spray was equivalent with that of damp heat. |
