橡胶膨胀节在运用的时候容易被腐蚀造成运用保存生命的年数短，为了进步提升防备尽量照顾作用，在实践运用时经常选用两种或两种以上具有不同作用机理的防老剂进行并用，或选用同一防备尽量照顾机理的防老剂并用，或选用在同一分子上按不同机理起作用的基团同时存在的防老剂，并用后作用有三种。对立效应是指两种或两种以上的防老剂并用时，所发作的防备尽量照顾作用小于她们.自运用时的作用之和，实践运用时应该防止这种景象发作。
Rubber joint at the time of using easily preserved by corrosion using years of life is short, in order to improve preparedness progress as far as possible to take care of the role, in practice often chooses two or above and with different mechanism of the stabilizer, or choose the same guard to take care of the mechanism of the stabilizer and as far as possible, or to choose according to the different mechanism of action on the same molecular groups of stabilizer at the same time, there are three kinds of effect after using.Oppositional effect refers to that when two or more anti-aging agents are used together, the protective effect is smaller than that of them. The sum of the effects of self-use should prevent this phenomenon from happening in practice.
研究标示，当显酸性的防老剂与显碱性的防老剂并用是，由于两者将发作相似于盐的复合物，由于这个发做对头立效应。别的，一般的链断开型防老剂与某些硫化物尤其是多硫化物之间也发做对头立效应。在富含1%的4010NA的硫化天然产生的乳胶中，加入多硫化物后使氧化效率进步提升，这也是对立效应。在富含芳胺或受阻酚的过氧化物硫化的纯天然产生的乳胶中，加入三硫化物，也发作有相是的景象。对立效应的发作与硫化物的构造有非常大联系，如二烯链硫化物与防老剂有清楚显露的对立效应，而二正丁基硫化物和三正己基三硫化物则无对立效应。一般单硫化物的影响比多硫化物小。炭黑在橡胶中既有抑氧化的作用，又有助氧化的作用。在链断开型防老剂炭黑按纳作用的减小，或在炭黑防老剂防备尽量照顾效能的下降，都清楚地标示她们之间发作了对立效应。
Studies have shown that when acidic and alkaline antisenders are used together, because both will attack a compound similar to salt, due to the headstand effect.In addition, the general chain - breaking anti - aging agent and some sulfides, especially polysulfides between head - to - head effect.The addition of polysulphides to natural sulfide latex, which is rich in 1% 4010NA, improves the oxidation efficiency, which is also the opposite effect.The addition of trisulphides to the naturally occurring latex, which is rich in aromatic amines or peroxide sulphides of blocked phenols, also has a similar effect.The occurrence of antagonistic effect is closely related to the structure of sulfides. For example, diene-chain sulfides and anti-aging agents have obvious antagonistic effect, while din-butyl sulphides and trihexyl trisulphides have no antagonistic effect.In general, the effect of monosulfide is less than that of polysulfide.In rubber, carbon black not only has the function of oxidation inhibition, but also helps oxidation.The decrease in sodium content of chain-breaking antioxidant carbon black, or the decrease in the effectiveness of carbon black antioxidant preparedness in trying to take care of aging, clearly marked the onset of opposing effects between them.
