| titleOfInvention | A kind of preparation method of polypropylene foaming beads |
| abstract | The present invention provides a kind of preparation method of polypropylene foaming beads, including first obtains polypropylene by the following method, then as matrix resin, addition organic peroxide and the polypropylene foaming beads are made using physical blowing agent foaming using gained polypropylene；Wherein, the polyacrylic preparation method is：In the reactor of two or more serial operations, the propylene polymerization of two benches or more is carried out, the external electron donor used in two benches reaction is respectively silane compound and diether compound.The present invention is using the high melt strength, propylene of wide molecular weight distribution as raw material, surface modifier using organic peroxide as EPP beads, it can prepare that cell diameter is uniform, abscess is fine and close, pore size distribution is uniform, the polypropylene foaming beads of hole-closing structure, be widely used in the fields such as automobile making, packaging, building heat preservation, sports equipment, daily necessities and Aero-Space. |
