摘　　要：研究了不同螺杆组合方式对玻纤增强苯乙烯-丙烯腈共聚物(AS)材料挤出工艺和材料力学性能的影响;并设计出一种适合于玻纤增强AS材料加工的螺杆组合方式。结果表明:合理的螺杆组合可改善玻纤增强AS材料的挤出工艺,提高材料的力学性能。通过改善熔融段和剪切段的螺纹组合,使玻纤增强AS材料的拉伸强度和弯曲强度分别由原来的105 MPa和115 MPa提高到了116 MPa和125 MPa,并保证了设备产量。采用合适的螺杆组合生产的材料能够满足国内外家电企业的要求。The effect of different screw assemblies on the extruding process and mechanical properties of glass fiber reinforced styrene-acrylonitrile copolymer （AS） was studied, and a suitable type of screw assembly for reinforced AS was designed. The results showed that the proper screw assembly could improve the extruding process and upgrade the mechanical properties of the reinforced AS. By improving melting and shear effect of the screw assemblies, the tensile strength and flexural strength of glass fiber reinforced styrene-acrylonitrile copolymer were improved obviously, from 105MPa and 115MPa to 116MPa and 125,MPa respectively. Moreover, it ensured the production of equipment. The quality of product met the requirements of home appliances manufacturing enterprises at home and abroad.
