| titleOfInvention | A kind of preparation method of polypropylene foaming beads |
| abstract | The present invention provides the preparation method of a kind of polypropylene foaming beads, and described expanded bead uses HOPP to be matrix resin, and with APP as fire retardant, foaming prepares in the presence of blowing agents；Wherein said HOPP is adopted and is prepared with the following method: in the reactor of two or more serial operations, carrying out two benches or above propylene homo closes reaction, the external electron donor used in two benches reaction is respectively silane compound and diether compound.The present invention is with the high melt strength, propylene of wide molecular weight distribution as raw material, realize the stabilisation of pp material, foaming window is effectively expanded, technique is prone to adjust, low cost, can prepare that cell diameter is uniform, abscess is fine and close, the polypropylene foaming beads of even aperture distribution, hole-closing structure, can be applicable to the occasion that foam plastic product is had relatively high fire-retardance to require by automobile component, electronic packaging and building decoration etc.. |
