Study on the Properties and Mechanism of Flame Retarded Glass Fiber Reinforced Polyamide 6 with Microcapsulated Aluminum Hypophosphite

Abstract:

Aluminum hypophosphite can be used to flame retard glass fiber reinforced polyamide 6 (GFPA6). TGIC microcapsulated AlHP (T-AlHP) and epoxy resin microcapsulated AlHP (E-AlHP) were made and put into GFPA6. The vertical burning tests and mechanical tests were taken to study the flame retardant performance and mechanical properties of the corresponding composites. Addition of either T-AlHP or E-AlHP resulted in an increased UL-94 rating and a decreased comprehensive mechanical performance. T-AlHP endowed GFPA6 a better flame retardancy than E-AlHP did. TG showed the decomposition behaviors of T-AlHP, E-AlHP, and the corresponding composites. From Py-GC/MS, the detailed pyrolysis products of flame retardants and the flame-retardant composites were identified. Finally, the properties and mechanism of flame retarded GFPA6 with these two kinds of microcapsulated Aluminum Phosphate were summarized.
