In this work, the effect of thermo-oxidative aging on organic montmorillonite/intumescent flame retardant/long glass fiber–reinforced polypropylene composites was investigated for different exposure times at 140°C. Limiting oxygen index, Underwriters Laboratories-94 tests, cone calorimeter test, and thermogravimetric analysis were used to evaluate the flammability and thermal stability. The results of limiting oxygen index values, Underwriters Laboratories 94 test, and cone calorimeter test show that aging performs negative effect on the flame retardancy of organic montmorillonite/intumescent flame retardant/long glass fiber–reinforced polypropylene composites. Thermal oxidation aging markedly changes the decomposition process of organic montmorillonite/intumescent flame retardant/long glass fiber–reinforced polypropylene composites. The scanning electronic microscopy images of the external surface of composites indicate that many ground particles and micro-scale cracks are scattered in the surfaces of the composites after aging. The sharp micro-scale cracks and crazing formed on the surface promote the heat and oxygen to penetrate into the bulk of polypropylene matrix. According to the mechanical test results, the thermal oxidation aging reduces the tensile, flexural, and notched impact strengths of organic montmorillonite/intumescent flame retardant/long glass fiber–reinforced polypropylene composites.

Ul 94

The effects of brominated flame retardant which composed of decabromodiphenyl ethane (DBDPE) and antimonous oxide (AO) on long glass fiber reinforced polypropylene (LGFPP) were investigated by means of limiting oxygen index (LOI), vertical burning (UL-94), thermogravimetry analysis (TGA), and mechanical properties. With the increase of DBDPE-AO content, the LOI values of DBDPE-AO/LGFPP composites increased from 21 to 27.6, and when the content of DBDPE-AO was 16wt%, the composites passed the V-0 rating in UL-94 testing. The experimental results showed that the brominated flame retardant improved flame retardancy of LGFPP, which was proved by the TGA testing. Whats more, the mechanical properties of composites even improved compared with pure LGFPP.
