Borophosphate, borate phosphate, and metal borophosphate as novel flame proofing additives for plastics
First Claim
1. A mixture comprising at least one plastic K and from 0.1 to 30% by weight, based on the entire mixture, and at least one compound A which is a metalloborophosphate selected from the group consisting of NH4[ZnBP2O8], Rb[ZnBP2O8], Cs[ZnBP2O8], NH4[(Zn1-xCox)BP2O8] (x=0, 0.1, 0.2, 0.3, 0.4, 0.5, 0.6, 0.7, 0.8, 0.9, 1.0), Na[ZnBP2O8].H2O, (C4N3H16)[Zn3B3P6O24].H2O, (C6N4H22)1.5[Zn6B6P12O48].1.5H2O, NH4[ZnBP2O8], K[ZnBP2O8], [MBP2O8] (M=B, Al, Ga), and mixtures thereof.
