Embodiment approach

[0030] According to one embodiment of the present invention, the polyurethane foam comprises the cyclic phosphate ester in an amount of about 1 to about 20 weight percent based on the total weight of the polyurethane foam, and in another embodiment, the cyclic phosphate ester is included in an amount of about 3 to about 18 weight percent cyclic phosphate ester. In yet another embodiment of the present invention, the polyurethane foam comprises a cyclic phosphate ester in an amount of about 5 to about 15 weight percent based on the total weight of the polyurethane foam.

[0031] According to one embodiment of the present invention, the polyurethane foam includes the melamine compound in an amount of about 1 to about 20 weight percent based on the total weight of the polyurethane foam, and in another embodiment, the melamine compound is included in an amount of about 2 percent by weight based on the total weight of the polyurethane foam. To about 18 weight percent melamine compo...

Abstract

The invention relates to flame retarded polyurethane foam containing, inter alia, an effective flame retarding amount of a non-halogen flame-retardant mixture wherein said foam is capable of meeting or exceeding stringent flame retardancy criteria.

Description

technical field [0001] The present invention relates to flame retardant additives for incorporation into polyurethane foams. More particularly, the present invention relates to mixtures of cyclic phosphate esters and one or more melamine compounds and the use of such mixtures as flame retardant additives for polyurethane foams. Background technique [0002] Flame retardant additives are often used to reduce the risk and severity of burning in polyurethane foams. Various flame retardants are known and commercially available for this purpose. However, there are often considerable technical problems and toxicological concerns that limit the use of these flame retardants. [0003] Flexible polyurethane foams are widely used as cushioning or cushioning materials, for example, in furniture and in motor vehicles. Flame retardants are typically incorporated into such foams. However, it has been difficult to confirm that sufficient flame retardancy will be obtained economically w...
