| titleOfInvention | A kind of preparation method of the polypropylene expanded PP Pipe Compound based on sorbitol acetal class compound |
| abstract | The present invention relates to a kind of technology of preparing of the polypropylene expanded PP Pipe Compound of sorbitol acetal class compound, the parts by weight of raw material composition are：The volume ratio of 100 parts by weight of polypropylene, 0.1 ~ 0.7 parts by weight of initiator, 0.1 ~ 1 parts by weight of sorbitol acetal class compound, 0.05 ~ 1 parts by weight of benzene-type aromatic hydrocarbons grafted monomers, benzene-type aromatic hydrocarbons grafted monomers and solvent is 1 ~ 15.Specific preparation process：Polypropylene is added in from the main spout of extruder；Initiator and sorbitol acetal class compound are added in from the auxiliary feed system of extruder；Benzene-type aromatic hydrocarbons grafted monomers are dissolved in solvent and are added in from the liquid addition port of extruder, while opens and squeezes out the vacuum pump of drive end unit to pump solvent and unreacted grafted monomers, reactive extrursion, cooling, granulation is carried out, obtains polypropylene expanded PP Pipe Compound.The present invention provides a kind of technology of preparing simple for process, operating the polypropylene expanded PP Pipe Compound with high fondant-strength and excellent processing fluidity flexible, suitable for continuous industrial production. |
