Relating to a block copolymer dye, the invention provides a silicon nitrogen containing flame retardant type polymer dye and a preparation method thereof. Polymethacryloxypropyl polyhedron oligomeric silsesquioxane is adopted as a first block, and polymethacrylate azobenzene is taken as a second blocker to prepare a halogen-free flame retardant block copolymer dye by means of reversible addition-fragmentation chain transfer. The self-assembly effect of a POSS group in the dye molecule can significantly improve the dye molecule fastness and reduce dye molecule migration, and through introduction of an azo group (-N=N-) and the POSS group, the material can be endowed with good flame-retardant and anti-dripping performance. By adjusting the feeding proportion of the two monomers, the content of silicon and nitrogen flame retardant elements in the polymer dye molecules can be controlled, and the method has the advantages of simple synthesis process, mild reaction conditions, easy control of reaction, and is suita
