Description

一种防伪垃圾袋的制备工艺
技术领域
本发明涉及一种垃圾袋的制备工艺，尤其涉及一种防伪垃圾袋的制备工艺。
背景技术
PBAT属于热塑性生物降解塑料，是己二酸丁二醇酯和对苯二甲酸丁二醇酯的共聚物，兼具PBA和PBT的特性，是一种结晶度高、非极性的热塑性树脂。原态PBAT 的外表呈乳白色，在微薄截面呈一定程度的半透明状。PE 具有优良的耐大多数生活和工业用化学品的特性。某些种类的化学品会产生化学腐蚀，例如腐蚀性氧化剂（浓硝酸），芳香烃（二甲苯）和卤化烃 （四氯化碳）。该聚合物不吸湿并具有好的防水蒸汽性，可用于塑料袋用途。然而其通常不具有防伪功能，用于某些需要防伪的领域时，需要在塑料袋上另外设置专门的防伪标识，比如印刷防伪油墨，或粘贴防伪标签等，即影响了产品的外观，又增加了加工工序。
发明内容
本发明为了解决现有技术中防伪垃圾袋制备工艺复杂，且制备出的垃圾袋防伪标志易复制的问题，提供了一种防伪垃圾袋的制备工艺。
本发明为了解决上述问题，所采取的技术方案为：一种防伪垃圾袋的制备工艺，包括以下步骤
a 将改性淀粉和PBAT放入混合机进行混合形成混合体A；
b 向混合机中添加防伪组分后加入相容剂与混合体A进行混合形成混合体B；
c 将表面活性组分和抗氧剂混合后加入混合机中与混合体B混合形成混合体C；
d、通过螺杆上料机，混合好的物料输送到连续密炼机料储料罐；
e、通过粉体计量喂料机，喂料到连续密炼机；
f、将聚异丁烯加到液体计量喂料机，喂料到连续密炼机；
g、挤出造粒；
e、成品包装。
进一步的，所述防伪组分包括以下质量分数的组分
编码物质 1-70%
荧光粉 10-20%
载体树脂 10-80%。
进一步的，所述防伪组分的制备方法为：将载体树脂、荧光粉和编码物质按配比称量，倒入高混机中混合均匀，在双螺杆挤出机中140~200℃熔融，挤出造粒，得到防伪母粒。
进一步的，所述步骤a的混合温度为20-30℃，混合时间为10-30min。
进一步的，所述步骤b的混合温度为30-50℃，混合时间为10-20min。
进一步的，所述混合体c中粉料含水量<2%。
本发明所产生的有益效果包括：本发明中的防伪垃圾袋制备工艺过程简单，混合温度较低，能源成本低，且生产出的垃圾袋防伪标志不易去除和复制，保证了垃圾袋的防伪性能。
