SPRAY FOAMS CONTAINING NON-HALOGENATED FIRE RETARDANTS

摘要

A spray foam formulation used to form a spray foam insulation layer in a wall structure is described. The formulation may include the reaction product of a polyisocyanate compound and a polyol compound; a fire retardant chosen from at least one of a non-halogenated fire retardant; and a reactive halogen-containing fire retardant, and a carbohydrate. The spray foam insulation layer has an insulative R value of 3.0 to 7.2 per inch, and a density of between about 0.3 to about 4.5 pcf. Further, spray foam insulation made from the spray foam formulation may have fire retardant characteristics that are equivalent to or better than a similar spray insulation foam insulation using non-reactive halogenated fire retardants such as tris(1-chloro-2-propyl)phosphate (TCPP).

1. An insulated structure, comprising:
a plurality of structural support members coupled together to form a frame; a plurality of first wall boards attached to an exterior side of the frame to form an exterior wall or surface of the structure; and a spray foam insulation positioned within at least one of the wall cavities of the structure, the spray foam insulation comprising a spray foam having an insulative R value of 3.0 to 7.2 per inch and a density of between about 0.3-4.5 pcf, the spray foam made from a formulation that comprises:
a reaction product of a polyisocyanate compound and a polyol compound;a fire retardant chosen from at least one of a non-halogenated fire retardant, and a reactive halogen-containing fire retardant; anda carbohydrate.
