为了改善橡胶等高分子材料的耐老化性能,必须减少或延缓自动氧化速度,一般在化学上有两条主要途径可以达到这一目的:一是中断连锁反应过程。能够起到中断连锁反应过程作用的物质就是断链抗氧剂,或称连锁破坏抗氧剂;二是防止引发游离基的形成,能够起到防止引发游离基形成作用的 In order to improve the aging resistance of rubber and other polymer materials, we must reduce or delay the rate of auto-oxidation, there are generally two major chemical routes to achieve this goal: First, to interrupt the chain reaction process. Can play a role in interrupting the chain reaction process of the material is chain scission antioxidant, or chain destruction of antioxidants; the second is to prevent the formation of free radicals, can play a role in preventing the formation of free radicals
