摘要:
采用热氧加速老化的方法研究了硅橡胶发泡材料(SRF)的老化性能,探究了不同老化时间对SRF材料的泡孔结构和性能的影响规律。结果表明,不同密度SRF的泡孔结构不同,密度较大的SRF泡孔尺寸较小,泡孔壁较厚,闭孔比例较大。在热氧老化过程中,随着老化时间的延长,泡孔结构逐渐遭到破坏;当老化时间相同时,密度越大的SRF泡孔结构遭到的破坏情况越严重。此外,结合SRF的泡孔微观结构和性能来看,SRF泡孔结构的破坏会导致其压缩永久变形率和应力损失率升高。
Abstract:
The aging properties of silicon rubber foam (SRF) were studied by using thermal-oxidative accelerated aging method, and the influence law of different aging time on cellular structure and properties of SRF was explored. The results showed that SRF materials with different densities had different cellular structure, and the large the density of SRF materials, the smaller cellular size, the thicker cellular wall and the larger the proportion of closed cell. In the process of thermal-oxidative aging, the cellular structure was destroyed with the increasing aging time. With the same aging time, the cellular structure of SRF materials with the higher density was destroyed more seriously. In addition, combined with the result of cellular microstructure and properties, it was found that the destruction of the cellular structure of SRF materials would lead to the increase of compression permanent deformation and stress loss rate.
