Study On Preparation And Properties Of ABS/PET Alloy

Poly acrylonitrile-butadiene-styrene (ABS) has balanced mechanical properties, such as toughness, hardness, rigidity. And it has good dimension stability, surface gloss, low temperature resistance, coloring process. But there is still inadequate, such as weatherability advantages, conductivity, heat resistant. These faults hampered further application of ABS.Therefore need to ABS resin modified. PET has the very good mechanical properties, chemical resistant solvent and thermal stability; But PET has its own shortcomings especially impact resistance performance is poor, will ABS, PET physical blend can make them performance complementary, get the best comprehensive properties of alloy.Because ABS is crystallization resin, PET is crystalloid resin, ABS/PET alloy is incompatible system, both direct blending appear easily statified, peeling phenomenon, material performance is poorer, add appropriate compatibilizer can improve both compatibility.and with the low price can greatly reduce PET cost, is instead of ABS/PBT alloy the best choice. This article through to the third components of the blending modified, in ABS/PET alloy with compatibilizers by twin-screw extruder blend alloy preparation, discusses the ABS and PET the best ratio and the type of compatibilizers, usage, then further study the ABS brand of ABS/PET influence on the performance of the alloy, toughening ABS/PET alloy, enhance ABS/PET alloy, on the basis of ABS/PET alloy and ABS/PBT alloy are compared. In order to realize the ABS/PET alloy engineering.
