Abstract

The invention belongs to the technical field of polymer materials, and relates to an ABS / PA6 material and a preparation method thereof. The ABS / PA6 material comprises the following components by weight: 100 portions of an ABS resin, 10-50 portions of PA6 resin, 20-80 portions of glass fiber, 5-15 portions of a compatible agent, 0.3-1.8 portions of a chain extension agent, 0.2-1.5 portions of a lubricant and 0.3-1.0 portion of an antioxidant. The ABS / PA6 material provided by the invention has excellent extrusion resistance, and weather resistance, oil resistance, solvent resistance and mechanical properties obviously superior to those of an unmodified ABS material, and extrusion products also have excellent performance. The ABS / PA6 material can be widely used in various areas of social life, such as pipelines, architectural section and sheet, and has great economic and social values.

Description

technical field [0001] The invention belongs to the technical field of polymer materials, and relates to an ABS / PA6 material for an extrusion process and a preparation method thereof. Background technique [0002] Acrylonitrile-butadiene-styrene (ABS) is widely used in various fields of social life because of its excellent mechanical properties, dimensional stability, easy processing, coloring, and convenient post-processing. One of the wide range of polymers, while ABS has the advantages of high melt strength and good extrusion performance. But at the same time, due to the disadvantages of low heat distortion temperature, poor chemical resistance, especially oil resistance and weather resistance of ABS plastic, its application is limited. [0003] Polycaprolactam (PA6) is a crystalline thermoplastic polyester with the advantages of non-toxicity, good weather resistance, good stability against chemicals, high mechanical strength and outstanding oil and solvent resistance. ...
