FIBERGLASS COMPOSITES WITH IMPROVED FLAME RESISTANCE FROM PHOSPHOROUS-CONTAINING MATERIALS AND METHODS OF MAKING THE SAME

摘要

Fiberglass products with increased flame resistance are described. The products may include fiberglass-containing thermal insulation that include a plurality of glass fibers coated with a phosphorous-containing flame retardant. The flame retardant may include an organophosphorous compound having a substituted or unsubstituted organophophorous group bonded to a substituted or unsubstituted amide group by a substituted or unsubstituted alkyl group. The fiberglass products may further include fiberglass composites that are about 50 wt. % to about 98 wt. % glass fibers, about 2 wt. % to about 50 wt. % of a binder; and a phosphorous-containing flame retardant. Also described are methods of making fiberglass products with increased flame resistance. These methods may include the steps of contacting glass fibers and/or fiberglass products with a flame retardant mixture that includes a phosphorous-containing compound.

主权项

1. A method of making glass fibers with improved flame resistance, the method comprising:
contacting glass fibers with an aqueous flame retardant mixture comprising an organophosphorous compound having a substituted or unsubstituted organophophorous group bonded to a substituted or unsubstituted amide group by a substituted or unsubstituted alkyl group; and drying the glass fibers to form the fibers with improved flame resistance.
