摘要
通过硅橡胶(甲基乙烯基硅橡胶)在热空气(空气)、纯水(水)、人工海水(海水)、湿热和湿热盐雾5种环境中的老化试验,探究湿热盐雾环境对硅橡胶老化性能的影响。结果表明:硅橡胶在不受力的状态下老化,水(汽)对老化后的拉伸强度和拉断伸长率的影响不明显;在受压缩应力的状态下老化,水(汽)对压缩永久变形有明显的影响;盐雾对硅橡胶的老化加速作用不明显,与在空气中老化的试验结果相比,湿热盐雾的加速老化效果与湿热的加速老化效果一致。
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.
