High-gloss anti-precipitation flame-retardant polypropylene material and preparation method thereof

The invention discloses flame-retardant masterbatch suitable for a flame-retardant polypropylene material, a preparation method of the flame-retardant masterbatch and a high-gloss anti-precipitation flame-retardant polypropylene material based on flame-retardant masterbatch preparation. Tetrabromobisphenol S bis-(2,3-dibromopropyl) ether masterbatch is adopted as the flame-retardant masterbatch and prepared by taking micropore polypropylene as an adsorbing agent and a masterbatch carrier through a fusing adsorption method. Flame-retardant polypropylene based on flame-retardant masterbatch preparation is prepared from 57%-70% of polypropylene resin, 24%-40% of the tetrabromobisphenol S bis-(2,3-dibromopropyl) ether masterbatch and 3%-6% of antimonous oxide masterbatch. The high-gloss anti-precipitation flame-retardant polypropylene material prepared through the method has the advantages of being high in gloss, easy to mold and disperse, capable of resisting precipitation, low in cost, high in flame-retardant efficiency and the like and can be widely applied to shells of electrons, electric appliances and the like.
