Description

technical field [0001] The invention belongs to the technical field of polymer materials, and relates to an ABS / PBT material 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. At the same time, ABS has the advantages of high melt strength and good extrusion performance. But at the same time, ABS plastic also has disadvantages such as low heat distortion temperature, poor chemical resistance, especially oil resistance, and poor weather resistance, which limit its application. [0003] Polyethylene terephthalate (PBT) has the advantages of non-toxicity, weather resistance, good stability against chemicals, high mechanical strength, outstanding oil resistance and solvent resistance, and is cheap, but due to low visco...
