Polyamide/acrylonitrile-butadiene-styrene copolymer alloy and its prepn

Abstract

The present invention relates to one kind of polyamide / acrylonitrile-butadiene-styrene copolymer alloy and its preparation process. The polyamide / acrylonitrile-butadiene-styrene copolymer alloy is prepared with polyamide 35-60 wt%, acrylonitrile-butadiene-styrene copolymer 8-50 wt%, compatilizer 2-10 wt%, flexibilizer 2-15 wt%, antioxidant stabilizer 0.2-2 wt%, lubricant 0.3-3 wt%, and nucleator 0.1-2 wt%. The preparation process includes weighing the materials based on the weight proportion, mixing in a high speed mixer for 1-4 min, mixing, melting and extruding in a double screw extruder, and pelletizing. The polyamide / acrylonitrile-butadiene-styrene copolymer alloy has simple processing and molding process and high performance.

Description

[technical field]

[0001] The invention relates to the technical field of polymer materials, in particular to a polyamide / acrylonitrile-butadiene-styrene copolymer alloy and a preparation method thereof. [Background technique]

[0002] As the first of the five major engineering plastics, polyamide has a series of excellent physical and mechanical properties determined by its special molecular structure. However, due to its large shrinkage, strong water absorption, and poor dimensional stability, the addition of ABS resin can just overcome the above shortcomings. , the prepared alloy material combines the heat resistance and chemical resistance of polyamide materials, and the toughness and rigidity of ABS, and has good impact strength, heat warpage resistance, excellent fluidity and surface gloss , Has been applied in electrical and electronic, automobile, furniture, sporting goods and other fields. However, the existing polycaprolactam (PA6) and acrylonitrile-butadiene-styre...
