Abstract

The invention discloses a high-performance recycled PET/ABS alloy. The alloy comprises the following components in percentage by weight: 30 to 80 percent of recycled PET, 10 to 50 percent of ABS, 1 to 10 percent of reinforcing agent, 2 to 15 percent of compatilizer, 0.5 to 5 percent of flexibilizer, 0.5 to 3 percent of polyhydroxy chemical coupling agent, and 0.1 to 1 percent of antioxidant. The alloy can improve a recycled PET system by using reasonable matching of additives, effects of the polyhydroxy chemical coupling agent, and excellent physical mechanic properties of an ABS system. Therefore, the recycled PET /ABS alloy has the advantages of high compatibility, high tensile strength, high mobility, good machinability and the like, is particularly suitable for producing complicated components and parts and large plates, has a simple process, is suitable for mass production of medium-sized and small enterprises, and has obvious economic benefit and social benefit.

Example Embodiment

[0037] Example 1
[0038] Weigh 80.0% of dried recycled PET flakes, ABS resin 10.1%, AS resin 1.0%, AS-g-MAH 3.0%, polybutadiene rubber 5.0%, ethylene glycol 0.5%, antioxidant Tetrakis(β-(3,5-di-tert-butyl-4-hydroxyphenyl)propionic acid) pentaerythritol ester (antioxidant 1010) 0.4%. The mixed materials are added to the twin-screw extruder, melted and blended, extruded and pelletized into alloy materials. Among them, the processing temperature is 190~235℃, the residence time is 2~3min, and the melt pressure is above 12MPa.
