Flammability Test

A new flame retardant for cotton, tetramethylol 2,4-diamino-6-(3,3,3-tribromo-1-propyl)-1,3,5-triazine (TM-DABT), was synthesized. TM-DABT was applied to cotton fabrics from a combination of water and dimethylformamide by a pad-dry-cure process. It polymerized rapidly on fabric at 140°C to give excellent flame retardancy. Flannelette and twill with add-ons of 13.3% and 11.3%, respectively, passed the FF3–71 flammability test after 50 laundering, with char lengths of 4.7 and 3.4 inches. There was evidence of cellulose crosslinking because fabrics had improved wrinkle-recovery angles, and cotton fibers were insoluble in cupriethylenediamine hydroxide. The finish was heat-sensitive, as evidenced by noticeable yellowing when white fabrics were cured at 150°C or above, or when they were laundered repeatedly. Various physical properties of the fabrics are presented, as well as oxygen index and thermogravimetric analyses.

A novel phosphorus-silicon containing flame-retardant DOPO-V-PA was used to wrap carbon nanotubes (CNTs). The results of FTIR, XPS, TEM and TGA measurements exhibited that DOPO-V-PA has been successfully grafted onto the surfaces of CNTs, and the CNTs-DOPO-V-PA was obtained. The CNTs-DOPO-V-PA was subsequently incorporated into epoxy resin (EP) for improving the flame retardancy and dispersion. Compared with pure EP, the addition of 2 wt% CNTs-DOPO-V-PA into the EP matrix could achieve better flame retardancy of EP nanocomposites, such as a 30.5% reduction in peak heat release rate (PHRR) and 8.1% reduction in total heat release (THR). Furthermore, DMTA results clearly indicated that the dispersion for CNTs-DOPO-V-PA in EP matrix was better than pristine CNTs.
