Description

一种利用回收的废旧PET塑料制备编织袋的工艺
技术领域
本发明涉及编织袋领域，尤其涉及一种利用回收的废旧PET塑料制备编织袋的工艺。
背景技术
PET为聚对苯二甲酸二醇酯，PET的韧性极佳,其薄膜的拉伸强度比PC的高出三倍,比PE高出九倍,可以与铝膜相比美,而且比其它塑料膜的冲击强度高出四倍多，且具有长期耐热氧老化性能，饮料瓶、矿泉水瓶等包装瓶用PET己经成为回收再利用的主要方向，塑编行业产量巨大，废旧PET的应用空间很大，但纯回收PET的扁丝拉丝难度较大，如果可以将废旧PET应用到塑料编织袋的生产中，对生态的可持续发展将具有长远而重要意义。
发明内容
本发明为实现废旧PET作为原料用于制备编织袋中提供了一种制备工艺，利用废旧PET塑料与PP和PE共混从而达到编织袋所要求的强度。

(3)共混前料准备：将回收的PP、相容剂、抗氧剂和填充剂按配方比例加入到高速混合机中，高速混合1-2min后出料，将混合物加入到单螺杆挤出机中熔融混炼；将废旧PET塑料、扩链剂、抗氧剂按配方比例加入到高速混合机中，高速混合2-3min，加热到150～160℃，密闭输送到另一台双螺杆挤出机中增粘；
(4)共混：单螺杆挤出机和双螺杆挤出机挤出的熔体直接加入到第三台双螺杆挤出机中进行共混，通过熔体计量泵和T型机头挤出；
(5)拉丝：螺杆挤出机熔融，用平膜法以薄膜形式挤出并水冷，切刀将薄膜纵向切割成坯丝，坯丝经过烘箱被拉伸为扁丝，扁丝通过热定型和牵伸取向后在卷绕机上收卷成型；
(6)织布：将扁丝分为经线和纬线，将经线通过送经倒辊和跳杆上下交替的棕丝，使经线间形成开口、闭合、反向开口、闭合，即经线开交，同时，纬线随梭子和经线开口沿水平做圆周运动，将经纬线编制成织布并将织布收卷；
(7)切袋：对织布进行电晕处理，然后将电晕好的织布进行切袋；
(8)印刷：对编织袋内表面进行印刷。
所述的相容剂为HDPE-g-MAH、LLDPE-g-MAH、LDPE-G-MAH和PP-g-MAH中的一种或多种。
