| 中文摘要: |
| 对8种不同类型的硫化橡胶在大气老化试验时的应力松弛变化进行了探讨。研究结果表明，橡胶的大气老化是一个复杂的化学过程，硫化橡胶的化学应力松弛变化能反映出这种过程的矛盾变化。各种橡胶的应力松弛速率的不同，反映出其耐老化性能的不同，因而硫化橡胶的化学应力松弛可以用来评价橡胶的耐候性。 |
| 英文摘要: |
| The stress relaxation of 8 types of vulcanizates during the atmospheric aging test has been evaluated. The results show that the atmospheric aging is a complex chmical process which can be reflected by the chemical stress relaxation of the vulcanizates. The chemical stress relaxation of the vulcanizates can be used to evaluate the aging properties of rubber because the different stress relaxation rates of various vulcanizates reflect their different aging properties. |
