AI Technical Summary
PET has problems such as low crystallization temperature and slow crystallization rate leading to slow molding, low notched impact strength, and poor resistance to thermo-oxidative aging, which limit its application range.
By preparing a PET composite material, using a specific ratio of toughening agent with glycidyl methacrylate functional groups, sarin resin and plasticizer, combined with PET resin of specific molecular weight and molecular weight distribution index, a PET composite material with rapid molding, impact resistance and heat and oxygen aging resistance is prepared using a twin-screw extruder.
This has enabled the rapid molding, impact resistance, and heat and oxygen aging resistance of PET materials, thus broadening their application range.
