Fire retardant nonwoven mat and method of making

摘要

Described is a fiber glass mat composition comprising a fiber glass matrix bonded with fire retardant melamine resin binder composition capable of forming a nonwoven mat having at least 27% by weight nitrogen (N) in the dry, bur uncured resin. Also described is a method of making a fire retardant nonwoven fiber glass mat comprising the steps of providing an aqueous melamine based resin binder; applying the binder to fiber glass; and recovering a fire retardant fiber glass mat, wherein the mat has at least 27% by weight N in the dry, but uncured resin wherein the ratio of resin in the mat to N content of the resin does not exceed about 0.6.
