Abstract

The invention provides a polyphenyl ether / ABS (Acrylonitrile Butadiene Styrene) alloy which is prepared from the following raw materials in percentage by weight: 10-60% of polyphenyl ether, 10-60% of ABS, 2-20% of flexibilizer, 1-10% of compatilizer, 0.2-0.6% of antioxidant and 0.2-0.6% of lubricant. The invention also provides a preparation method which comprises the following steps of: firstly blending and extruding the polyphenyl ether and the compatilizer (maleic anhydride), and then extruding with other raw materials and granulating. In the preparation process of the polyphenyl ether / ABS alloy, the compatibility between polyphenyl ether and ABS is improved by use of the fractional mixing compatibility technology and unique compatilizer, thus the polyphenyl ether / ABS alloy has the advantages of good mechanical properties, excellent appearance, high impact resistance and insulating property, low cost and the like, is easy to process and form and resistant to solvents, can be electroplated, and has wide application prospects.

Description

technical field [0001] The invention relates to a modified polyphenylene ether material, in particular to a polyphenylene ether / ABS alloy and a preparation method thereof. Background technique [0002] The chemical name of polyphenylene ether (Polypheylene ether, PPE) is poly 2,6-dimethyl-1,4-phenylene ether, which has good mechanical properties, chemical stability, dielectric properties, heat resistance and flame retardancy. Is a high-performance thermoplastic engineering plastics. However, the molecular chain of PPE is relatively rigid and is very sensitive to notch impact. At the same time, due to its high melt viscosity, it cannot be injection molded, which greatly limits its use. At present, PPE is rarely used alone, and more than 90% of commercial products are obtained by blending with other polymers or chemically modifying them. [0003] Acrylonitrile-butadiene-styrene copolymer (ABS) has excellent impact resistance, heat resistance, low temperature resistance, chem...
