Abstract:
A rABS/PBT/ASG composite material and a preparation method thereof utilize the characteristics of rABS with carboxyl and hydroxyl groups, wherein rABS are pre-blended with ASG to increase the viscosity, so that the epoxy groups on the ASG molecules react with the hydroxyl groups and the carboxyl groups on the rABS, and the acrylonitrile-styrene segments in ASG and rABS are thermodynamically miscible, followed by reacting and blending with PBT to prepare the rABS/PBT/ASG composite material. ASG acts as a chain extender and solubilizer in the mixture. The mixture prepared in this way have good compatibility, and the tensile strength, impact strength and elongation at break of the composite material are comprehensively improved. The composite material obtained has the advantages of both ABS and PBT materials, which has broad application prospects in the field of ABS plastic recycling.
