Abstract
The invention relates to a polymer material and a preparation method thereof, and concretely relates to an isomeric crosslinking technology toughened and reinforced recovered PBT and PET alloy and a preparation method thereof. The method comprises the following steps: carrying out air blasting drying on the recovered PBT and PET alloy at 120DEG C for 24h; and weighing dried recovered PBT and PET alloy, a crosslinking master batch and a nucleating agent according to weight proportions, adding the weighed materials into a high speed mixer, mixing for 4-6min, and carrying out extruding granulation by adopting a double screw extruder at 220-260DEG C under a screw rotating speed of 140r/min to obtain the isomeric crosslinking technology toughened and reinforced recovered PBT and PET alloy. Toughening adopted in traditional recovery methods and realized through increasing the amount of an elastomer toughening agent usually causes decrease of the tensile property of the recovered PBT and PET alloy and influences the integral mechanical performances; and the reinforcing and toughening effects of the recovered PBT and PET alloy can be realized, an isomeric crosslinking technology is introduced to make the regenerated material have very good toughness and strength without adding a compatilizer in the regeneration process of the recovered PBT and PET alloy, so the toughened and reinforced recovered PBT and PET alloy has extremely great market popularization values.
