The effects of anti-aging agents mainly include internal factors and external factors: the internal factors are the molecular structure, volatility and oxidation resistance of rubber raw materials.External factors mainly include the structure of rubber raw materials and the use of external environment interference.The following is a brief analysis from three aspects: the structure, the loss rate and the concentration of the anti-aging agent.
Structure of anti-aging agent
The anti - aging agent can delay the aging speed of rubber.Substituent group can obviously reduce the energy of hydrogen free group, when the electronic gene and electronegativity of substituent group is small, it can enhance the anti-aging effect of anti-aging agent.When the electron gene and electronegativity of the substituent group are large, the energy of hydrogen free group can be increased, and the anti-aging ability of the anti-aging agent can be reduced.Related studies show that the dissociation of n-h bond plays an important role in the aging rate of rubber in amine antiaging agents.When the molecular chain contains an anti-aging agent that can reduce n-h bond substituents, it can delay the oxidation reaction of rubber by controlling the oxygen absorption of rubber raw materials in the aging process of rubber products.
