Abstract

The invention falls into the technical field of polymer composite material, and discloses PA / ABS alloy material and a preparation method thereof. The PA / ABS alloy material comprises (by weight parts) PA 30-80, ABS 10-50, an antioxidant 0.1-0.5, a compatilizer 3-10, a lubricant 0.1-0.5, an antistatic agent 2-10 and a flame retardant 10-20. The preparation method includes putting all above raw materials in a high-speed mixer, mixing for 2-5 minutes, and extruding and granulating by a screw extruder to obtain the PA / ABS alloy material. The inventive PA / ABS alloy material has stable size, high strength, good appearance, high fluidity and resistance to chemicals, and possesses antistatic and flame retardant effects at the same time, and therefore, can be widely applied in fields of electronics, automobile, etc.; owing to the antistatic and flame retardant functions of the PA / ABS alloy material, the PA / ABS alloy material can play a role of electrostatic prevention, dust prevention and flame retardance during application process.

Description

technical field [0001] The invention belongs to the technical field of polymer materials, and relates to a PA / ABS alloy material and a preparation method thereof. Background technique [0002] Nylon 6 / acrylonitrile-butadiene-styrene (PA / ABS) alloy was first introduced by Borg Wamer Chemicals and Monsanlo in the United States. It has a higher heat distortion temperature than PA and a higher Vicat temperature. Ideal materials for automotive parts such as body panels ([1] StolP M.et Knrtstofe PI Europe, 1995, 85 (41: 27); [2] Dunning L. Knnstofe Plast ELI, 1996.86 (I): 30; [3] Clereq Zub i M. et al Kunstoffe Plast Europe, 1997, 87(12):1814). [0003] Compared with PC / ABS, PA / ABS has low density, good matte effect, heat resistance, wear resistance, chemical resistance, decompression noise reduction, processing performance and other aspects have been greatly improved, so PA6 and ABS are combined Mixed, can be prepared not only ABS toughness, but also PA heat resistance and oil ...
