Abstract

The invention relates to a recycled polyethylene terephthalate / acrylonitrile-butadiene-styrene copolymer alloy and a preparation method thereof. The method comprises the following steps: 60-90% of recycled PET is recovered by weight percentage; ABS resin 2-30%; reinforcing agent 3-30%; compatibilizer 1-5%; antioxidant 0.1-0.5%; rare earth metal salt 0.1-0.5%; molecular weight regulator 0.1-2%; ~ 2%, mixed evenly by a high-speed mixer, then added to the extruder to extrude to obtain a strip. The processing temperature of the extruder from the feeding port to the grinding port is as follows: 180°C, 185°C, 190°C, 195°C , 200°C, 205°C, 210°C, 215°C, the extruder host speed is 80‑120r / min; the above strips are water-cooled and pelletized to obtain modified pellets. Compared with the prior art, the invention has the advantages of being suitable for industrial batch production, having excellent tensile strength, impact strength, high fluidity, high chemical stability and the like.

Description

technical field

[0001] The invention belongs to the technical field of polymer materials, and in particular relates to the preparation of a recycled PET / ABS alloy with high performance and low cost. Background technique

[0002] Polyethylene terephthalate (PET) is a kind of crystalline polyester with good organic solvent resistance, chemical resistance, self-lubricating performance and molding processing performance, etc. It is widely used in long fiber, food packaging bottles , plates, plastic steel strips, etc. With the wide application of PET materials, waste PET materials are gradually increasing. Waste PET materials are non-biodegradable materials. If these waste PET materials cannot be recycled well, it will not only cause waste of resources, but also cause environmental pollution.

[0003] ABS plastic is an acrylonitrile-butadiene-styrene copolymer, which has good comprehensive properties, high impact strength, chemical stability and good electrical properties. ABS ...
