Abstract
The present invention teaches an antimony free brominated flame retardant composition, comprising a brominated flame retardant, an organic phosphorus-containing flame retardant which is an organic phosphate that is either an amorphous solid or a liquid, and a flame retardant which is a source of nitrogen and inorganic phosphorus, this source being amorphous compound. The invention further teaches textile coating formulations comprising these compositions, a process for applying them on textile fabrics, and the flame retarded fabrics coated by these compositions and formulations.
Claims13
A textile flame retarded by a flame retardant composition, comprising:
- a. a brominated flame retardant, wherein said brominated flame retardant is selected from the group consisting of an aromatic brominated polymer, 2,2′[(1-methylethylidene) -bis-[(2,6-dibromo-4,1-phenylene)-oxymethylene]]-bisoxirane polymer with 2,2′,6,6′-tetrabromo-4,4′-isopropylidenediphenol and 2,4,6-tribromophenol (FR4002), tetrabromobisphenol A diglycidyl ether copolymer (FR4001), tetrabromobisphenol A bis-(2,3-dibromopropyl ether) (FR9001), decabromodiphenyl ethane (FR1410), and ethylene-bis-tetra-ibromo-phthalimide (BT-93),
- b. an organic phosphorus-containing flame retardant, said organic phosphorus-containing flame retardant being an organic phosphate that is either an amorphous solid or a liquid at room temperature,
- c. a flame retardant which is a source of nitrogen and inorganic phosphorus, said source being an amorphous inorganic phosphate salt, wherein said inorganic phosphate salt is Aluminum Ammonium superphosphate;
- wherein the textile is antimony-free and has bromine content in the range from 4% to 22% of the total weight of the textile, passing ASTM D6413 flammability test.
