| Résumé : |
Two-component polyurethane flame retardant coatings were prepared using phosphorus-containing lactone modified polyesters (PLMPs) and polyisocyanate. PLMPs were synthesized by polycondensation of dimethyl phenylphosphonate, a flame retardant component with polycaprolactone, adipic acid, and trimethylolpropane. PLMPs were prepared with dimethyl phenylphosphonate content from 10 to 20 wt%. It was found that various physical properties of these new flame retardant coatings were comparable to non-flame retardant coatings. The flammability of coatings depends strongly on the dimethyl phenylphosphonate content in PLMP. Coatings with 20 wt% dimethyl phenylphosphonate content did not burn in the vertical burning test. |
