Description

具有阻燃性能的多层导电泡棉
技术领域
本发明涉及导电泡棉技术领域，具体涉及一种具有阻燃性能的多层导电泡棉。
背景技术
在泡棉本体上包裹导电布，在导电布与泡棉本体之间设有热熔胶，热熔胶将导电布与导电泡棉粘合成一体结构，经过一系列的处理后，使其具有良好的表面导电性，可以很容易用胶粘带固定在需屏蔽器件上。导电泡棉可用于从事电子、电磁等高辐射工作的屏蔽措施中。目前市场上大多的导电泡棉制作比较简单，不具有阻燃特性，给其使用带来了安全隐患，鉴于此，有必要对传统的多层导电泡棉作出改进。
发明内容
为解决现有技术的不足，本发明的目的在于提供一种强度高、韧性好、具有很好的导电性、隔热性和阻燃性能的多层导电泡棉。
为了实现上述目标，本发明采用如下的技术方案：

再优选地，前述隔热层的厚度为0.3~0.8mm。
更优选地，前述阻燃层由阻燃涂料喷涂而成，阻燃涂料包括如下按质量份计的各组分：丙烯酸树脂36~48份、聚酯树脂22~37份、二氧化镁15~28份、碳酸钙12~18份、硅酸钠11~15份、聚丙烯酰胺9~13份、邻苯二甲酸丁酯8~11份、二甲基苯胺7~12份、聚乙二醇6~9份、氧化铝7~9份、乙酸乙烯酯3~8份、分散剂3~7份、消泡剂4~6份和水21~30份。
进一步优选地，前述阻燃层的厚度为0.4~0.7mm。
具体地，前述分体泡棉层为2~4层，分体泡棉层为阻燃泡绵或吸波泡棉。
优选地，前述加强层为石棉，石棉的厚度为加强棉的十分之一。
再优选地，前述第一导电胶层的厚度为0.3~0.6mm。
更优选地，前述第二导电胶层的厚度为0.2~0.58mm。
本发明的有益之处在于：本发明的多层导电泡棉的强度高、韧性好、具有很好的导电性，其外侧的隔热层具有优异的隔热性能，在高温环境下也可保护器件的工作；阻燃层可以起到很好的阻燃性能，可有效防止泡棉易燃的现象，并阻止火源向四周扩散。
