Description

一种抗菌真空压缩袋的制备方法
技术领域
本发明涉及材料领域，具体的说，本发明涉及一种抗菌真空压缩袋的制备方法。
背景技术
随着人民生活水平的不断提高，人们对环境卫生和自我健康日益重视。与此同时，工业化的迅猛发展带来了各种环境污染问题，伴随着这些环境污染问题的出现，大量的致病菌和条件致病菌在人类生活的各个角落滋生蔓延。当这些有害细菌粘附到口常生活物品的表面上时，在条件合适的情况下就会迅速繁殖并伴随着人们的接触而蔓延传播，危害人类健康。
发明内容
本发明的目的在于提供一种抗菌真空压缩袋的制备方法。
为了实现本发明的目的，本发明提供一种抗菌真空压缩袋的制备方法，该方法包括：称取60千克的基础树脂、35千克的抗菌剂、和5千克的相容剂，所述基础树脂包含相同重量的醋酸乙烯-乙烯共聚物和低密度聚乙烯(LDPE Q281，上海石化)，基于所述醋酸乙烯-乙烯共聚物的总重量，所述醋酸乙烯-乙烯共聚物的醋酸乙烯含量为20重量％，所述抗菌剂具有下列结构：
所述相容剂为二甘醇单丁醚己二酸酯，放入高速搅拌机中混合均匀，再用双螺杆挤出机挤出造粒，得到共混料，称取30粒料置于1mm厚的模框中，在上下模温度为180℃的模压机上先预热6min，然后以5.0MPa的压力热压4min，再以10.0MP的压力冷压至常温，即得。
本发明还提供具有下列结构的物质在用作压缩袋抗菌剂中的用途：
本发明所述的抗菌真空压缩袋具有良好的抗菌效果，值得大规模推广使用。
具体实施方式
以下通过具体实施方式的描述对本发明作进一步说明，但这并非是对本发明的限制，本领域技术人员根据本发明的基本思想，可以做出各种修改或改进，但是只要不脱离本发明的基本思想，均在本发明的范围之内。
实施例1
称取60千克的基础树脂、35千克的抗菌剂、和5千克的相容剂，所述基础树脂包含相同重量的醋酸乙烯-乙烯共聚物和低密度聚乙烯(LDPE Q281，上海石化)，基于所述醋酸乙烯-乙烯共聚物的总重量，所述醋酸乙烯-乙烯共聚物的醋酸乙烯含量为20重量％，所述抗菌剂具有下列结构：
所述相容剂为二甘醇单丁醚己二酸酯，放入高速搅拌机中混合均匀，再用双螺杆挤出机挤出造粒，得到共混料，称取30粒料置于1mm厚的模框中，在上下模温度为180℃的模压机上先预热6min，然后以5.0MPa的压力热压4min，再以10.0MP的压力冷压至常温，即得样品1。
实施例2
按照和实施例1相同的方式制备样品2，不同之处在于不使用具有下列结构的抗菌剂：
实验例
按企业标准QB/T2591-2003、使用大肠杆菌ATCC 25922进行测试。结果如下：实施例1的样品在24小时后试件菌落数(CFU/片)为12，而实施例2的样品在24小时后试件菌落数(CFU/片)为2.1×105。实施例1的结果与实施例2的结果进行比较，差异具有统计学意义(P<0.05)。
