一种聚烯烃与聚酯的共混回收方法
摘要：
本发明涉及一种聚烯烃与聚酯的共混回收方法，其步骤如下：(1)、将聚酯回收料破碎成0.3～5cm×0.3～5cm见方的碎片，然后进行干燥，聚酯回收料碎片干燥结束后水分含量小于100ppm；(2)、将干燥后的聚酯回收料碎片与接枝剂、增容剂一起加入同向双螺杆挤出机进行挤出，挤出的料条经水冷造粒即得回收塑料粒子。本发明具有的优点为能实现聚烯烃与聚酯回收料的有效回收再利用。
摘要（英）：

The invention relates to a polyolefin-polyester blending recovery method which comprises the following steps: (1) crushing recovered polyester into 0.3-5cm*0.3-5cm square fragments, and drying until the moisture content is 100 ppm; and (2) adding the dried recovered polyester fragments, a grafting agent and a compatibilizer into a corotating double screw extruder, extruding, and granulating by cooling the extruded material with water, thereby obtaining the recovered plastic granules. The invention can implement effective recovery and reutilization of the recovered polyolefin and polyester.
