一种真空收纳袋及其制备方法
技术领域
本发明涉及真空收纳袋技术领域，具体涉及一种真空收纳袋及其制备方法。
背景技术
真空压缩袋，顾名思义，就是抽走空气让大气压自然造成压缩的一种袋子。简单点说，真空压缩袋，主要用于装棉被和各种衣服类的一种袋子。真空压缩袋具有防潮、防霉、防蛀、防异味等特点。
现有的真空压缩袋制成材料分为两种类型组合，一种是PE材料+尼龙材料复合而成，该种组合存在以下问题：一是PE材料脆易损坏，尼龙材料价格贵；二是后期回收时PE材料+尼龙材料不融合，不能回收，环保性能差；第二种是PE材料+PET材料复合而成，该种组合的优势是价格相对较低，但同样存在材料脆易损坏的现象，透气率高达120cc㎡/24h，一次使用后很难再次使用，浪费严重。
有鉴于此，特提出本发明。
发明内容
本发明的目的在于提供一种真空收纳袋及其制备方法，该真空收纳袋采用布料和PE膜制成，布料柔软耐折，厚实耐磨，不易发脆，使用寿命长，此外，本申请制备真空收纳袋的布料和PE膜的种类较多，可以根据需要进行选择，进而使制备得到的真空收纳袋应用范围更广。

具体实施方式
下面将结合实施例对本发明技术方案的实施例进行详细的描述。以下实施例仅用于更加清楚地说明本发明的技术方案，因此只作为示例，而不能以此来限制本发明的保护范围。
需要注意的是，除非另有说明，本申请使用的技术术语或者科学术语应当为本发明所属领域技术人员所理解的通常意义。
本发明实施例提供一种真空收纳袋，该真空收纳袋包括袋体，该袋体上设置有抽气阀门和密封拉链；
袋体由内膜层和外膜层通过胶粘复合而成，内膜层的表面设置有阻隔层；
外膜层材质为布料。
本发明真空收纳袋采用布料和内膜层制成，布料柔性更好，不易碎，使用寿命长，此外，在内膜层表面设置阻隔层，能够阻断空气，实现抽真空，达到真空收纳的目的。
在一些实施方式中，布料种类包括涤纶类、棉麻类、无纺布类和涤棉混纺类等等。布料种类较多，可以根据需要进行选择，进而使制备得到的真空收纳袋应用范围更广。
在一些实施方式中，内膜层材质可以为普通PE膜、增强PE膜、流延PE膜或多层共挤PE膜。PE膜种类较多，可以根据需要进行选择，进而使制备得到的真空收纳袋应用范围更广。
在一些实施方式中，胶粘采用的胶水为水性复合胶水、热熔胶、聚氨酯胶水或油胶。本发明真空收纳袋可以采用多种胶水进行胶粘，适于在多钟不同性能的设备上使用，同时也适应不同温度的环境要求。
在一实施方式中，阻隔层材质可以为PVA乳液或者其他具有阻隔效果的乳液；可以达到阻隔气体进入袋体作用，且透气率达≤10cc㎡/24h。
本发明实施例还提供了一种真空收纳袋的制备方法，该制备方法包括如下步骤：
(a)对PE膜进行电晕处理，再将水性PVA乳液涂布在PE膜表面，然后进行烘道烘干，得到内膜层；经测试，将水性PVA溶液涂布后得到的内膜层透气率在10cc㎡/24h以内，较尼龙膜50cc㎡/24h，PET膜120cc㎡/24h的效果要好多倍，此外，烘道长度不低于15m，由于PE薄膜耐高温性差，一般的烘道温度控制在60～90℃之间，通过烘道长度达到烘干效果，另外，PE薄膜非拉伸薄膜，含有0.5～1.5㎝左右的收缩，再因烘干温度不高，所以生产线速须控制在40～50米/min左右；
(b)通过胶粘方式将布料和内膜层进行复合并固化成型；布料与PE薄膜通过胶水复合后，需要通过温度对胶水进行活化，凝固从而将两层材料紧紧的粘合在一起，一般烘房温度在45～60℃之间，固化时间12-36h；
(c)在布料表面印刷图案得到布塑膜材；通过印刷使产品外观更漂亮、有卖点；
(d)在布塑膜材上进行切口并安装抽气阀门，然后，根据不同大小调整好宽度、长度对制袋机的封烫刀段进行加油进行封边封、封底封和封拉链，得到上述真空收纳袋。
在一些实施方式中，步骤(b)中，当胶粘采用的胶水为热熔胶时，通过胶粘方式将布料和内膜层进行复合具体包括：
将热熔胶融化后涂布在布料表面，再将电晕后的内膜层压合在布料表面；
当胶粘采用的胶水为水性复合胶水或聚氨酯胶水时，通过胶粘方式将布料和内膜层进行复合具体包括：
将水性复合胶水或聚氨酯胶水涂布在布料表面，然后进行烘道烘干，再将电晕后的内膜层压合在布料表面。
在一些实施方式中，步骤(d)中，封底封和封边封时制袋机的封烫刀温度可以为150～180℃；封拉链时制袋机的封烫刀温度可以为160～190℃。
