Description
技术领域
本发明属于高分子材料技术领域，具体涉及一种气相防锈聚丙烯双向拉伸薄膜。
背景技术
目前气相防锈膜是一种近年来发展较快的金属防护包装材料，它是基于高分子材料与VCI气相防锈技术发展相结合的新一代创新高科技产品。使用该膜将被防锈物品包装密封后，膜体内含有的VCI开始升华挥发出防锈气体因子，扩散渗透至被防锈物品表面并吸附其上，形成单分子厚的致密保护膜层，隔绝诱发锈蚀的各种因素与被防锈物品表面的接触，从而有效防止锈蚀的产生。
但是，市场上传统的气相防锈膜阻燃性能、可拉伸性能差，且功能较为单一，不具有抗静电、抗紫外线等功能，因此如何克服现有技术的不足是目前高分子材料技术领域亟需解决的问题。
发明内容
本发明的目的是为了解决现有技术的不足，提供一种气相防锈聚丙烯双向拉伸薄膜，本发明产品具有良好的可拉伸性能和阻燃性能，并且能够抗静电、抗紫外线，是一种理想的金属包装材料。
本发明采用的技术方案如下：
一种气相防锈聚丙烯双向拉伸薄膜，其特征在于包括按照重量份数计的如下原料：聚丙烯100~120份、氮系阻燃剂12~14份、单甘脂1~2份、抗氧剂1076 0.2~0.5份、4-(N,N-二正丁基)-胺甲基吗啉5~12份、抗粘连剂3~5份、紫外线吸收剂UV-531 0.5~1份、六甲基磷酰三胺0.2~0.5份。
进一步，其优化方案为所述的氮系阻燃剂为氰尿酸三聚氰胺盐。
进一步，其优化方案为所述的抗粘连剂为聚甲基丙烯酸甲酯。
本发明的制备方法：按照上述重量份数称取各原料，将其放入低速搅拌机中搅拌均匀，然后将混合物料通过双螺杆挤出机熔融共混，挤出造粒，干燥，然后流延成片材，最后利用双向拉伸设备将片材拉伸成BOPP薄膜，即得到本发明产品。
本发明与现有技术相比，其有益效果为：（1）本发明产品以4-(N,N-二正丁基)-胺甲基吗啉为气相缓蚀剂，具有良好的气相防锈功能，同时添加了氮系阻燃剂，并综合了聚丙烯双向拉伸薄膜的缠绕拉伸功能，不仅使得本发明产品具有良好的阻燃性能，还可使包装器件的密封性好，包装膜不松脱；（2）本发明产品具有优良抗静电功能，它可以保护机械部件，特别是电子产品不受静电损坏；（3）本发明产品具有良好的抗紫外线功能，可防止内包装物因紫外线照射而降解、褪色。
