Release time：2013-06-06
Because each kind of rubber antioxidant protection function are limited, and rubber products in the actual use of the aging is affected by many factors, so in the choice of rubber antioxidant should pay attention to the following points:
(1) because each rubber antioxidant different characteristics, and different rubber formula of different aging properties. Therefore, a rubber material the most effective rubber antioxidant, might be in another rubber material is invalid or even harmful. Therefore, the rubber antioxidant selection should be based on all kinds of rubber material aging resistance, prevent ageing requirements, as well as the characteristics of all kinds of rubber antioxidant overall consideration, reasonable choice.
(2) when a rubber antioxidant is difficult to meet the requirements should be used when two or more rubber antioxidant, make its produce and coordinated action to ensure that the aging effect.
(3) some rubber antioxidant for rubber have shading effect and pollution phenomenon. Generally speaking, phenolic rubber antioxidant protective effect is poor, but not pollution or pollution is small. And the protective effect of higher amine rubber antioxidant, can make rubber pollution, discoloured. These problems should be considered in selecting plan as a whole.
(4) rubber antioxidant amount shall not exceed the solubility in the rubber, in order to prevent the crocking, pollution rubber surface quality.
(5) amine rubber antioxidant for rubber material scorch have bad influence; Phenolic rubber antioxidant can delay vulcanization, in selecting should be paid attention to.
