Performance comparison of the amine antioxidant in the tread rubber and cushion rubber

Rubber Antioxidant 4010NA, rubber antioxidant RD, antioxidant DKF a 50 Antioxidant BLE belong to the amine antioxidant. Amine antioxidant is the most varieties of rubber antioxidant, the protective effect of the most prominent of rubber antioxidant, and its main protective effect of anti-oxidation, anti-ozonation and it h has a significant the protective effect to eat, heavy metals and UV-catalyzed oxidation and fatigue aging. Four amine antioxidant performance comparison in the tread rubber and cushion rubber conclusions are as follows:

 

A. Four rubber antioxidant has an impact on the vulcanization performance of the scorch time.

 

B. In the formula thermal aging process of rubber buffer, Rubber Antioxidant 4010NA single increase, the aging coefficient larger, indicating that the protective effect. Four rubber antioxidant in the quantitative and rubber antioxidant RD in the 48h thermal aging protective effect than the rubber antioxidant BLE rubber antioxidant RD This product is of high molecular weight, diffusion loss protection performance remains longer than the sake of length.

 

C. In the tread formula thermal aging process, the four rubber antioxidant rubber antioxidant 4010NA quantitative and the other three rubber antioxidant increases monotonically better protective effect than the monotonous reduction and use of protective effect.

 

D. The use of the experimental formula by the production, process performance and stability of plastic materials, the product did not find any quality problems. Reasonable choice with use of the protective agent, will help improve the comprehensive performance of aging resistance and tire rubber.
