Abstract: A phosphorus-containing flame retardant formulation (C1) comprises (wt.%) at least one resin (0.1 - 99.9, preferably 4.4 - 82.3, especially 18.8 - 69.9) of an organic nitrogen compound and at least one phosphorus-containing flame retardant (0.1 - 99.9, preferably 17.7 - 95.6, especially 30.1 - 81.2). Independent claims are also included for the following: (1) a phosphorus-containing flame retardant formulation (C2) comprising a two-component phosphorus-containing flame retardant formulation containing (wt.%) component A (0.1 - 99.9, preferably 68.9 - 94.2,especially 68.9 - 87.9) and a component B (0.1 - 99.9, preferably 5.83 - 31.1, especially 12.1 - 31.1). The component A is the at least one resin of an organic nitrogen compound (12.9 - 93.7 or 1.5 - 93.7) and at least one non-particulate phosphorus-containing flame retardant (6.3 - 87.1 or 6.3 - 98.5), and component B is a metal compound (M1) selected from an aluminum compound, titanium compound, zinc compound, tin compound and/or zirconium compound; (2) a phosphorus-containing flame retardant formulation (C3) comprising a two-component phosphorus-containing flame retardant formulation containing (wt.%) a component C (0.1 - 99.9, preferably 13.3 - 95.6, especially 22.3 - 86.8) and a component D (0.1 - 99.9, preferably 4.4 - 86.7, especially 13.2 - 77.7). The component C is at least one resin of an organic nitrogen compound (9.6 - 67.5, preferably 51.5 - 67.5) and (M1) (32.5 - 90.4, preferably 32.5 - 48.5) and component D is at least one non-particulate phosphorus-containing flame retardant; (3) a phosphorus-containing flame retardant (C4) comprising a three-component phosphorus-containing flame retardant formulation containing (wt.%) a component E (0.1 - 99.9, preferably 1 - 65, especially 11 - 59), at least one resin of an organic nitrogen compound, a component D (0.1 - 99.9, preferably 4 - 87, especially 13 - 78), at least one non-particulate phosphorus-containing flame retardant and a component B (0.1 - 99.9, preferably 12 - 32, especially 12 - 38) and (M1); (4) preparation (P1) of the phosphorus-containing flame retardant formulation (C1) involving mixing at least one organic nitrogen compound, formaldehyde and, optionally, at least one solvent at 10 - 300 [deg] C for 0.1 - 100 hours, to form a mixture, and incorporating into the mixture at least one mono- or polyfunctional amines, and also amine and at least one particulate or non-particulate phosphorus-containing flame retardant and, optionally (M1); (5) preparation (P2) of the phosphorus-containing flame retardant formulation (C2) involving, for preparation of component A, mixing dicyandiamide, formaldehyde, and solvent, and optionally at least one mono- or polyfunctional amine at 10 - 300 [deg] C for 0.1 - 100 hours, and adding the at least one non-particulate phosphorus-containing flame retardant to form a mixture, and mixing (M1) into the mixture; (6) preparation (P3) of the phosphorus-containing flame retardant formulation (C3) involving, for preparation of component C, mixing dicyandiamide, formaldehyde, and solvent, and optionally at least one mono- or polyfunctional amine at 10 - 300 [deg] C for 0.1 - 100 hours, to form a mixture, adding the metal compound to the mixture and mixing the at least one non-particulate phosphorus-containing flame retardant; (7) preparation (P4) of the phosphorus-containing flame retardant formulation (C4) involving, for preparation of component E, mixing dicyandiamide, formaldehyde, and solvent, and optionally at least one mono- or polyfunctional amine at 10 - 300 [deg] C for 0.1 - 100 hours, adding the at least one non-particulate phosphorus-containing flame retardant to form a mixture, and mixing (M1) into the mixture; (8) a process (P5) for providing flame retardancy to paper, cardboard or paperboard involving adding the phosphorus-containing flame retardant formulations to the fiber suspension of the paper, cardboard or paperboard during engine sizing; (9) a process (P6) for providing flame retardancy to a textile involving applying the phosphorus-containing flame retardant formulation (C1) in the form of an impregnating solution to the textile; (10) a process (P7) for providing flame retardancy to wood involving introducing the wood into an impregnating system, exposing the wood for at least 20 minutes to a pressure of 50 mbar, impregnating the wood at a pressure of 16 bar for 1 - 10 hours with an impregnating solution comprising the phosphorus-containing flame retardant formulation (C1); or coating the wood via by a dipping process, spraying process, or spreading process, with a coating component comprising the phosphorus-containing flame retardant formulation (C1); (11) a flame-retardant cellulose-containing molding comprising 0.01 - 90 wt.% of the components selected from cellulose, the at least one resin of an organic nitrogen compound, the at least one non-particulate phosphorus-containing flame retardant and (M1); or 0.01 - 90 wt.% of the components selected from cellulose, the at least one resin of an organic nitrogen compound, the at least one particulate phosphorus-containing flame retardant; and (12) a flame-retardant cellulose-containing molding comprising (wt.%) cellulose (1 - 50), dicyandiamide-formaldehyde resin or melamine-formaldehyde resin (each 1 - 30), and at least one particulate phosphorus-containing flame retardant (1 - 50).
