Abstract

The invention discloses a high-toughness scratch-resistant ABS/PBT alloy material and a preparation method thereof. The material is prepared from 37-75 parts of ABS resin, 20-50 parts of PBT resin, 2-5 parts of compatilizer, 3-8 parts of thermoplastic polyurethane elastomer, 0.5-2 parts of inorganic nucleating agent, 0.5-2 parts of scratch resistant agent, 0.2-0.4 part of antioxidant, 0.5-1 part of lubricant and 0-2 parts of other auxiliaries. Accordingly, macromolecule containing an epoxy functional group serves as the compatilizer, the thermoplastic polyurethane elastomer serves as flexibilizer, the compatibility of ABS and PBT is improved, the toughness and scratch-resistant property of the alloy material are improved, a melt extrusion method is adopted, the prepared material has the high toughness and the excellent scratch-resistant property, the material is simple in technology, convenience is brought to operate, the yield is high, and the material is suitable for industrial production and has the wide market prospect in the fields of vehicle interior and exterior trimming, household appliances, electrical and electronic products and the like.

Description

technical field [0001] The invention relates to the technical field of polymer composite materials, in particular to a high-toughness, scratch-resistant ABS / PBT alloy and a preparation method thereof. Background technique [0002] Acrylonitrile-butadiene-styrene (ABS) has the characteristics of excellent mechanical properties, high gloss, cold resistance, impact resistance, oil resistance, high dimensional stability, small molding shrinkage, excellent electrical properties, electroplating, and easy molding. It is widely used in automobiles, home appliances, electronic toys and other fields, but there are disadvantages such as poor weather resistance, low heat distortion temperature, especially poor resistance to organic solvents, which limit the expansion of its application range. [0003] Polybutylene terephthalate (PBT) is a crystalline polyester, which has the advantages of good resistance to organic solvents, high rigidity, chemical resistance, self-lubricating propertie...
