Abstract

The invention discloses a PLA (polylactic acid) resin-ABS (acrylonitrile-butadiene-styrene) resin composite material and a method for preparing the same. The PLA resin-ABS resin composite material is prepared form the following components by weight percent: 60-80% of PLA resin and copolymer thereof, 10-30% of ABS resin, 3-5% of compatibilizer, 5-10% of toughening agent, 0.5-2% of talcum powder and 0.5-1.5% of coupling agent. The components in proper content range interact mutually during extrusion, thus the PLA resin and ABS resin composite material has advantages of excellent impact strength, heat distortion temperature and biodegradable properties. The method for preparing the PLA resin and ABS resin composite material adopts the simple one-step mixing reaction-extrusion-granulation process, is convenient to operate, has high benefit and low cost and is suitable for industrial production.

Description

technical field [0001] The invention belongs to the technical field of chemical industry, and in particular relates to a polylactic acid-ABS resin composite material and a preparation method thereof. Background technique [0002] Polylactic acid is a thermoplastic aliphatic polyester that is artificially synthesized from corn and other crops and can eventually be decomposed into carbon dioxide and water in the environment, and will not cause pollution or damage to the environment. It has good mechanical properties and biodegradability, and is often used in biodegradable plastics. Biodegradable plastics can't exist in the environment for a long time due to its important advantage of being compostable and degradable, so it is often used in disposable consumer packaging materials, hotel keys, gift cards and other daily consumables. field. [0003] At present, there is research on compounding bio-resins to make composite materials, which can be applied in the field of durable ...
