| 中文摘要: |
| 通过甲基乙烯基硅橡胶（简称硅橡胶）在热空气（空气）、纯水（水）、人工海水（海水）、湿热和湿热盐雾5种不同老化环境中的对比试验，探究湿热盐雾环境对硅橡胶力学性能的影响。结果表明：在不受力的状态下，水对硅橡胶拉伸强度等力学性能的影响不明显；在压缩应力作用下，水对硅橡胶压缩永久变形有明显的加速作用；与空气中试验结果相比较，湿热盐雾对硅橡胶的老化加速作用不明显，其加速效果与同等湿度条件下硅橡胶的加速效果一致。 |
| 英文摘要: |
| 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. |
