Abstract

The invention discloses an ABS (acrylonitrile butadiene styrene) /PET(polyethylene terephthalate)/copolyester ternary alloy and a preparation method thereof. The ABS/PET/copolyester ternary alloy comprises the following components in parts by weight: 20-70 parts of ABS resin, 10-50 parts of PET resin, 2-50 parts of copolyester, 1-5 parts of assisted compatilizer, 0.5-1.5 parts of antioxygen and 0.5-1.5 parts of processing agent. The preparation method comprises the following steps: pre-mixing the components by a high-mixing machine, adding the mixture into a twin-screw extruder, extruding in the temperature ranging from 170 DEG C to 250 DEG C through plastifying and mixing; and cooling and pelleting to prepare the alloy. Compared with the prior art, the ABS resin and PET resin are taken as material matrixes and the copolyester as a bulking agent is added, so that the compatibility of the ABS and PET resins and the copolyester is improved, and the ternary alloy has high the advantages of high impulse strengthen, excellent flowability and low cost, and the ratio of the main components in the alloy can be adjusted to obtain a series of modified materials with different physical mechanical properties.

Description

Technical field [0001] The invention belongs to the technical field of polymer materials, and specifically relates to an ABS / PET / copolyester ternary alloy. Background technique [0002] ABS resin combines the rigidity and heat resistance of acrylonitrile, the toughness of butadiene and the gloss and processing fluidity of styrene. It is widely used in electronics, electrical appliances, automobiles, textile equipment, construction and daily necessities. PET has good electrical properties, but poor physical and mechanical properties, so its application in engineering plastics is limited. Many documents at home and abroad have introduced the preparation and application of ABS / PET alloy materials. However, the compatibility of ABS and PET is poor. Although many compatibilization methods can promote the compatibility of the two phases, the effect is still not ideal. [0003] Copolyester refers to polyester materials prepared by copolymerization of multiple acids and glycols, mainly i...
