Overview

Randomized trial shows improved flame retardancy and UV aging resistance in polypropylene, suggesting a new material application.

Key Points

  • This research aims to develop a novel triazine N-alkoxyamine to improve the flame retardancy and UV aging resistance of polypropylene.
  • Developed a low-basicity N-alkoxyamine compound (CDMP) as a synergist for intumescent flame retardants (IFR) in polypropylene.
  • Tested the composite with 0.3 wt% CDMP and 19.7 wt% IFR for mechanical and thermal properties.
  • Conducted Py-GC/MS analysis to investigate radical generation under combustion and photo-oxidation.
  • Achieved a limiting oxygen index (LOI) of 33.0% with CDMP and IFR composite.
  • Reduced total heat release (THR) by 22.2% and total smoke production (TSP) by 37.6%.
  • Demonstrated minimal UV-induced surface damage after 120 hours, with a carbonyl index growth rate of 87.2% compared to neat polypropylene.
