Description

Technical Field

[0001] The utility model relates to the technical field of extrusion devices, in particular to an extrusion device for polypropylene processing. Background Art

[0002] Polypropylene is a semi-crystalline thermoplastic plastic. Among them, random copolymer polypropylene pipes have the advantages of light weight, no scaling, and long service life. They are widely used in the industry. Since the heat resistance of random copolymer polypropylene pipes is not ideal, the process adopts melt extrusion reaction grafting technology to graft polyethylene molecules on the polypropylene molecular skeleton as long-chain lacing molecules to obtain polypropylene heat-resistant toughening modifier. The polypropylene heat-resistant toughening modifier is physically mixed with the random copolymer polypropylene resin material, and the material is then heated and melted through an extrusion device and extruded.

[0003] In polypropylene processing, traditional extruders usually do not have filtering functions, which makes it difficult to filter and separate large particles in the material. Large particles entering the material can easily affect the quality of subsequent extrusion processing, and even cause the extruded material to break easily. Therefore, it is necessary to redesign the polypropylene extruder to solve the problem of reduced extrusion quality caused by large particles. Utility Model Content
