Inventors:

David H. Blount - San Diego CA 92120

International Classification:

C09K 2110

US Classification:

Abstract:

Flame retardant compositions of this invention are produced by incorporating an amino condensation compound or composition in a more flammable organic compound. The amino condensation compounds and compositions are produced by heating urea or heating urea with other nitrogen containing compounds that will condensate with or react with isocyanic acid and/or cyanic acid or heating urea first then reacting the condensation compounds with other nitrogen containing compounds. The amino condensation compounds may be mixed with or reacted with carbonization auxiliaries, aldehydes and mixed with fillers to produce an amino condensation composition which is incorporated in more flammable organic compositions such as polyurethanes, polyester resins, epoxy resins, vinyl resins and other resins. The amino condensation salts of phosphorus, boron or sulfur containing compounds and the amino condensation-aldehyde resins may also be used as the flame retardant compound in this invention. For example, polyurethane foams can be rendered less flammable with the amino condensation compounds or compositions and utilized as insulating materials.

US Classification:

252601, 252609

Abstract:

Flammable organic material is made less flammable by incorporating a polynitrogen containing salt of polyboron oxyacid in or on the material. The polynitrogen containing salt of polyboron oxyacid is produced by reacting a boron oxyacid or salt of boron oxyadd with a nitrogen containing salt forming compound such as ammonia, amino compounds and amines in water. Both the polynitrogen radical and the boron oxyacid radical are both flame retardant agents. The polynitrogen salt of boron oxyacids may be used to form a flame retardant compositions by mixing it with carbonization auxiliaries and fillers. The polyammoniun alkali metal salts of polyboron oxyacids are useful as flame retardant agents and as a surfactant.
