The Weather-Resistant Modification Effect of AEPDS Decays Too Fast in the Accelerated Aging Test

Fenómeno del problema
The weather-resistant modification effect of AEPDS decays too fast in the accelerated aging test
Análisis de la causa
The AEPDS ultraviolet absorption mechanism decays after long-term exposure The accelerated aging conditions are too harsh and do not represent the actual environment The interaction between AEPDS and the matrix resin affects the weather resistance AEPDS partially degrades during processing and the weather-resistant function is lost Other components in the formulation accelerate aging
Solución
Verify the actual outdoor aging rather than only the accelerated test Increase the AEPDS addition amount to compensate for the decay Optimize the formulation to reduce aging-accelerating components Control the processing temperature to avoid AEPDS degradation Add auxiliary antioxidants to enhance weather resistance
Conclusión clave
AEPDS weather resistance needs actual verification and formulation optimization
