| titleOfInvention | A kind of high melt strength polypropylene and preparation method thereof |
| abstract | A high-melt-strength polypropylene, made from the following raw materials by weight: polypropylene 92.70-99.79%, organic peroxide 0.01-0.30%, o-diallyl bisphenol A diglycidyl ether 0.10- 4.00%, polycarboxy compound 0.10-3.00%; the ratio of the number of moles of carboxyl groups of the polycarboxy compound to the number of moles of epoxy groups of o-diallyl bisphenol A diglycidyl ether is 0.5:1.0-3.0:1.0. The present invention also provides a preparation method of the above-mentioned high melt strength polypropylene. The high melt strength polypropylene prepared by the invention not only has the advantages of high melt strength, but also has extremely low total migration and VOC value, which ensures that the high melt strength polypropylene fully complies with the food safety certification, and guarantees safety and health of consumers. The invention has the advantages of continuous production, high production efficiency and low processing cost, and can meet the needs of large-scale production. The high melt strength polypropylene in the present invention is suitable for processing and forming processes based on extensional flow fields, such as autoclave foaming, molding foaming, extrusion foaming, thermoforming, film blowing, and blowing. |
