Unsatisfactory Toughening Effect of Modified Acrylate-Epoxy-Phosphate-Distyrene Copolymer
Fenómeno del problema
The toughening effect of modified acrylate-epoxy-phosphate-distyrene copolymer is unsatisfactory, and the impact strength improvement is lower than the expected target
Análisis de la causa
The toughening agent addition amount is insufficient or the dispersion is uneven
The compatibility between the toughening agent and the matrix is poor and the interfacial bonding is weak
The processing temperature is improper (deviating from 200-260°C), and the toughening agent degrades or is poorly dispersed
Insufficient mixing, and the toughening agent agglomerates
The particle size of the toughening agent does not match
Solución
Increase the toughening agent addition amount to a reasonable ratio
Select a toughening agent with good compatibility with the acrylate-epoxy-phosphate-distyrene copolymer
Reasonably set the processing temperature according to the 200-260°C range
Strengthen mixing to ensure uniform dispersion
Select a toughening agent with a suitable particle size
Conclusión clave
The toughening effect needs to be addressed from the addition amount, compatibility, and dispersion
