Description

一种掺入有粉体灭火介质的灭火气泡膜及其制作方法
技术领域
本发明属于气泡膜制备技术领域，具体涉及一种掺入有粉体灭火介质的灭火气泡膜及其制作方法。
背景技术
目前，气泡膜是以聚乙烯作为主要原料，再添加增白剂、开口剂等辅料，经230℃左右高温挤出吸塑成气泡的产品，是一种质地轻、透明性好、无毒无味的新型塑料包装材料，可对产品起防湿、缓冲、保温等作用。
现如今大量快递包裹内都会使用气泡膜覆盖快递件而对其进行保护。但是，一旦快递在运输过程中遇到明火，上述常规气泡膜会起到助燃的作用，因此所保护的快递件容易被烧毁，从而造成一定损失。因此，研制具备耐高温性能、阻燃性能且制造过程简单的气泡膜，对于进一步提升快递件的保护效果和降低火灾危险性具有重要意义。
发明内容
为了解决上述问题，本发明的目的在于提供一种掺入有粉体灭火介质的灭火气泡膜及其制作方法。
为了达到上述目的，本发明提供的掺入有粉体灭火介质的灭火气泡膜包括双层气泡膜基材和分布在双层气泡膜基材中且内部充填有粉体灭火介质的缓冲气泡，其中气泡膜基材由作为基料的聚乙烯和辅料按重量比组成。
所述的辅料包括树脂、生物降解添加剂、增塑剂、阻燃剂、开口剂和增白剂。
所述的聚乙烯、树脂、生物降解添加剂、增塑剂、阻燃剂、开口剂和增白剂的重量比为5-65:5-35:1-20:1-10:0.1-5:0.1-3:0.1-2。
所述的聚乙烯选自低密度聚乙烯、线性低密度聚乙烯和高密度聚乙烯中的任一种或三者混合使用,三者混合使用可改善灭火气泡膜表面的光滑度和透明度；树脂选自PVC-SC5树脂和PVC-SG4树脂中的任一种，聚合度为1000-1200,其可适当增加灭火气泡膜的耐热性、韧性和延展性；生物降解添加剂为BDP全生物降解添加剂,其是一种有机添加剂，不影响灭火气泡膜的保质期和强度；增塑剂选自邻苯二甲酸二丁酯、邻苯二甲酸二辛酯、磷酸三甲苯酯和氯化石蜡中的任一种；阻燃剂为DOPO,其结构中含有P-H键，对烯烃、环氧键和羰基极具活性，可反应生成许多衍生物，且其化学稳定性高，阻燃性能好；开口剂为PE薄膜开口剂,也称为爽滑剂、抗粘连剂或抗结剂；增白剂选自荧光增白剂OB和荧光增白剂OB-1中的任一种。
所述的粉体灭火介质包括ABC类超细干粉灭火剂、磷酸铵盐干粉灭火剂、碳酸氢盐干粉灭火剂、氯化盐干粉灭火剂、微纳米粉体灭火剂、氢氧化镁阻燃剂和氢氧化铝阻燃剂中的任一种或者任意多种组合。
本发明提供的掺入有粉体灭火介质的灭火气泡膜的制作方法包括按顺序进行的下列步骤：
1)将聚乙烯、树脂、生物降解添加剂、增塑剂、阻燃剂、开口剂和增白剂按5-65:5-35:1-20:1-10:0.1-5:0.1-3:0.1-2的重量比进行称重，并在混合机中充分搅拌均匀，制备成颗粒状气泡膜混合料；
2)将上述气泡膜混合料放入加热装置中，在高温下使其加热熔化成糊状物料；
3)将上述糊状物料送入吹膜机中，通过挤压、膨胀、拉扯和注入空气在内的过程制成圆筒状的薄膜，注入空气可以使薄膜的厚度更加均匀；
4)将上述圆筒状的薄膜切成两张片状薄膜，然后收到挤压机的卷筒上，将两张薄膜重叠在一起并经过压力辊而制成双层气泡膜基材，并通过加热使其软化；
5)将软化后的双层气泡膜基材慢慢卷绕在真空成型辊上，靠近真空成型辊上圆孔的薄膜被吸起而变成一个个真空小气泡；
6)通过真空成型辊上圆孔内的小型灌装孔，将粉体灭火介质通过真空小气泡上的输气孔洞填充在真空小气泡内，在此过程中真空小气泡逐渐膨胀最终形成贴合在真空成型辊上圆孔大小的饱满的缓冲气泡；随后对输气孔洞位置进行加热塑封，由此制成双层气泡膜基材；
7)最后将双层气泡膜基材经过冷却、定型、延展、铺平、牵引、点断和收卷在内的过程即可制成所述的掺入有粉体灭火介质的灭火气泡膜。
在步骤1)中，所述的混合机中的搅拌时间为20-30min，搅拌速度为300-500r/min，气泡膜混合料的粒径控制在0.2-0.3mm。
在步骤2)中，所述的加热装置的加热温度为230℃。
在步骤4)中，所述的加热温度为140－180℃。
在步骤6)中，所述的加热塑封温度为140-200℃。
与现有技术相比，本发明提供的掺入有粉体灭火介质的灭火气泡膜及其制作方法可以多种聚乙烯为基料制备出气泡膜，通过在混料过程中添加一定比例的阻燃剂，并用合适的方法在缓冲气泡中填充大量粉体灭火介质，可在不改变原有性能的前提下提高气泡膜整体的耐高温能力，且阻燃、灭火效果明显。同时，经过此加工工艺，本发明方法制备的气泡膜韧性强，不易损坏，且加工过程简单，产品有市场竞争力，能够带来更好的效益。

2)将上述气泡膜混合料放入加热装置中，在230℃的温度下使其加热熔化成糊状物料；
3)将上述糊状物料送入吹膜机中，通过挤压、膨胀、拉扯和注入空气在内的过程制成圆筒状的薄膜，注入空气可以使薄膜的厚度更加均匀；
4)将上述圆筒状的薄膜切成两张片状薄膜，然后收到挤压机的卷筒上，将两张薄膜重叠在一起并经过压力辊而制成双层气泡膜基材1，并通过加热使其软化；加热温度为180℃；
5)将软化后的双层气泡膜基材1慢慢卷绕在真空成型辊上，靠近真空成型辊上圆孔的薄膜被吸起而变成一个个真空小气泡；
6)通过真空成型辊上圆孔内的小型灌装孔，将氢氧化镁阻燃剂和氢氧化铝阻燃剂通过真空小气泡上的输气孔洞填充在真空小气泡内，在此过程中真空小气泡逐渐膨胀最终形成贴合在真空成型辊上圆孔大小的饱满缓冲气泡2；随后对输气孔洞位置进行加热塑封,由此制成双层气泡膜基材；

为了验证本发明的效果，本发明人对上述实施例1－4制备的气泡膜进行了点火实验。测试结果表明，实施例1制备的掺入有普通沙砾的气泡膜的点火时间明显早于实施例2－4制备的掺入有粉体灭火介质的灭火气泡膜，且由于沙砾分布的不均匀和覆盖火焰的不充分，实施例1制备的掺入有普通沙砾的气泡膜的火焰强度直至在熄灭前都明显强于实施例2－4制备的掺入有粉体灭火介质的灭火气泡膜。
对实施例2－4中制备的掺入有粉体灭火介质的灭火气泡膜进行两两对比，测试结果表明，相比于阻燃剂配比较多的实施例3，实施例2的点火时间略短，但燃烧速度较快；相比于阻燃剂配比较少的实施例4，实施例2的点火时间略长，且燃烧速度较慢；相比于阻燃剂配比最少的实施例4，实施例3的点火时间明显增长，且燃烧速度明显减慢。
最后应说明的是：以上所述仅为本发明的优选实施例而已，并不用于限制本发明。尽管参照前述实施例对本发明进行了详细的说明，对于本领域的技术人员来说，其依然可以对前述各实施例所记载的技术方案进行修改，或者对其中部分技术特征进行等同替换。凡在本发明的精神和原则之内，所作的任何修改、等同替换、改进等，均应包含在本发明的保护范围之内。
