| titleOfInvention | A kind of low halogen flame retardant polypropylene composition and preparation method thereof |
| abstract | The invention provides a low-halogen flame-retardant polypropylene composition and a preparation method thereof, comprising the following steps: reacting aluminum sulfate octadecahydrate, urea, sorbitol and water to obtain nano-aluminum whiskers; adding PEG to a magnesium chloride solution, Mix evenly; adjust the initial pH value of the solution with ammonia water-ammonium chloride buffer solution, keep a constant temperature in a water bath, slowly add a precipitant to the magnesium chloride solution and stir; after the reaction, age the suspension and filter; wash the filter cake, and dry to obtain nanometer Magnesium hydroxide whiskers; drying the polypropylene pellets; thermally refining the polypropylene pellets, adding coupling agent, nano-aluminum whiskers, nano-magnesium hydroxide whiskers and magnesium hydroxide, and continuing to heat-refining until the mixture is uniform; After the mixing is completed, it is placed in a mold, hot-pressed in a flat vulcanizer, and then cold-pressed to form; it is obtained by drying. The low halogen flame retardant polypropylene composition of the invention has low halogen flame retardant content, belongs to the low halogen flame retardant polypropylene material, has good environmental protection and has excellent flame retardant performance. |
