Description

Technical Field

[0001] The utility model relates to the technical field of nylon material processing, in particular to a fast melting extruder for producing nylon composite materials. Background Art

[0002] Polyamide, commonly known as nylon, is a general term for thermoplastic resins containing repeated amide groups ([NHCO]) on the main chain of the molecule, including aliphatic PA, aliphatic-aromatic PA and aromatic PA. Among them, aliphatic PA has many varieties, large output and wide application. Its name is determined by the specific number of carbon atoms in the synthetic monomer. It was invented by the famous American chemist Carothers and his research team.

[0003] At present, polyamide is mainly used for synthetic fibers. Its most outstanding advantage is that its wear resistance is higher than all other fibers, 10 times higher than cotton and 20 times higher than wool. Adding a little polyamide fiber to blended fabrics can greatly improve its wear resistance. When stretched to 3-6%, the elastic recovery rate can reach 100%; it can withstand tens of thousands of folding and bending without breaking.

[0004] However, the current melt extruders for the production of nylon composite materials still have the following disadvantages: the nylon raw materials need to be heated and melted and extruded after processing, and the continuous melting stage takes a long time, especially when multiple materials are mixed and melted, which requires a long equipment length, greatly increasing the production cost. In addition, when melting raw materials of different particle sizes, the time for complete melting is different, which can easily cause uneven melting or a long melting time, thereby resulting in poor melting effect of nylon production materials.
