| titleOfInvention | A kind of polypropylene-based chlorine element, polybrominated diphenyl ether and heavy metal mixed standard sample and preparation method thereof |
| abstract | The invention discloses a mixed standard sample of polypropylene-based chlorine elements, polybrominated diphenyl ethers and heavy metals and a preparation method thereof. The preparation method of the invention comprises the following steps: blending heavy metal compounds, polybrominated diphenyl ether flame retardants and chlorinated polyolefins to obtain a first mixture; blending the first mixture with polypropylene, a diffusing agent and an antioxidant , obtain a second mixture, wherein polypropylene is a mixture of polypropylene powder and polypropylene pellets; add the second mixture to an extruder, and melt extrusion and granulation to obtain the standard substance to be treated; The granules of the substance to be treated are added to the extruder, and the melt extrusion and granulation are repeated 2 to 5 times to obtain a mixed standard sample of polypropylene-based chlorine elements, polybrominated diphenyl ethers and heavy metals. In the present invention, heavy metal compounds, polybrominated diphenyl ether flame retardants and chlorinated polyolefins are used as raw materials, and by means of secondary mixing and multiple melting and granulation, a polymer with uniform dispersion of components, uniform and stable content and smooth appearance is prepared. Allenyl chloride, polybrominated diphenyl ethers and heavy metals mixed standard. |
