US Patent:

51751941, Dec 29, 1992

Filed:

May 11, 1992

Appl. No.:

7/881067

Inventors:

Robert W. Ward - Greensboro NC
Rogelio Tornero - Greensboro NC
Freeman J. Henderson - High Point NC

Assignee:

Triad-Fabco, Inc. - Greensboro NC

International Classification:

C08J 924

US Classification:

521 55

Abstract:

A flame retardant composition and process which is particularly useful for rebonded foam products. The composition of the present invention includes a solid component of magnesium sulfate, boric acid, decabromodiphenylethylene oxide (DECA) and antimony trioxide and a liquid component of halogenated phosphorous. The present invention is based upon the discovery of the synergism between boric acid and DECA. The process, according to the present invention, includes the steps of forming a dispersion of the solid portion of the flame retardant composition along with a small amount of water based adhesive to a mass of foam chips. The treated chips are then dried to permit handling and storage. The dried foam chips subsequently are mixed with a conventional urethane prepolymer binder and the liquid halogenated phosphorous flame retardant compound. After mixing the foam mass is transferred to molds and steamed to allow the binder to cure.
