Abstract

The invention relates to a production system for glass fiber enhanced PBT materials. The production system sequentially comprises a glass fiber / PBT fiber co-mixing device, a screw extrusion device, acooling device, a traction device and a pelletizing device. The screw extrusion device comprises five sections of heating areas including the first heating area, the second heating area, the third heating area, the fourth heating area and the fifth heating area correspondingly, and a filler adding device is arranged at the position of the fourth heating area of the screw extrusion device. According to the production system, the integral tension strength is obviously increased, and the warping performance of products is obviously improved.

Description

technical field [0001] The invention belongs to the technical field of reinforced PBT fibers, in particular to a production system for glass fiber reinforced PBT fibers. Background technique [0002] Polybutylene terephthalate (PBT) is an excellent thermoplastic material with very good chemical stability, mechanical strength, electrical insulation properties and thermal stability, but PBT has very weak hygroscopic properties, and its tensile strength is only 50MPa , The crystallization of PBT is very rapid, which will lead to bending deformation due to uneven cooling. Contents of the invention [0003] Purpose of the invention: The purpose of the present invention is to overcome the deficiencies in the prior art and provide a production system for glass fiber reinforced PBT materials with significantly increased overall tensile strength and significantly improved product warpage. [0004] Technical solution: In order to solve the above technical problems, a production sys...
