Preparation method and application of novel brominated flame retardant master batch

The invention discloses a preparation method and application of a novel brominated flame retardant master batch, and belongs to the technical field of thermoplastic resin flame retardance, OBDPE and DBDPE are added into a reactor to form a DBDPE-OBDPE solution DOS, active superfine ferrous carbonate is added, the mixture is stirred and mixed uniformly, the mixture is cooled and then crushed into primary powder, and the primary powder is dried to obtain the novel brominated flame retardant master batch. The preparation method comprises the following steps: preparing a brominated flame retardant, putting the brominated flame retardant, a synergistic flame retardant and an acid acceptor into an omnibearing planetary ball mill for ball milling, mixing the ball-milled mixed flame retardant with a compatilizer, a lubricant and dried resin, adding the mixture into a hopper of a screw extruder, extruding and granulating to obtain novel brominated flame retardant master batches, mixing the novel brominated flame retar
