人们普遍接受这样的事实:橡胶在使用过程中,性能将随所施加的应力和应变而变化。通常,重复变形或重复疲劳会引起橡胶制品韧性的变化或机械强度的丧失,从而导致其破坏。本文将评述如何应用促进剂和抗降解剂来提高橡胶制品耐疲劳性能的基本知识。有关其它材料的效果和更多的理论评述,有兴趣的读者可参阅。在反复变形的条件下,橡胶性能的变化主要是由热氧、臭氧或机械撕裂引起的。最好能够知道哪种因素导致了这种性能上的变化,但这常常是不可能的。使用中这些因素可能相互作用产生影响,而这种影响在实验室 It is generally accepted the fact that the performance of a rubber during use will vary with the applied stress and strain. In general, repeated deformation or repeated fatigue can cause a change in the toughness of a rubber product or a loss of mechanical strength leading to its destruction. This article reviews the basics of how to use accelerators and antidegradants to improve the fatigue properties of rubber products. Interested readers can read more about the effects of other materials and more theoretical comments. Under repeated deformation conditions, changes in rubber properties are mainly caused by thermal oxygen, ozone or mechanical tearing. It is best to know which factors lead to this performance change, but this is often not possible. The use of these factors may have an impact on the interaction, and this effect in the laboratory
