Description
技术领域
本发明属于导电泡棉技术领域,具体涉及一种新型超薄、高压缩性、高回弹性、防静电的导电泡棉及其制备方法。
背景技术
导电泡棉是一种缝隙屏蔽材料,其材质轻、可压缩且具有导通性, 常用于电子电气设备中的缝隙处提供导电连接和屏蔽作用。导电泡棉在电子产品电磁兼容设计和整改时是一种常用的导电材料。它不仅可以吸收产品结构的尺寸公差,填充部件间的缝隙,而且能够提供稳定的导电连接。例如,导电泡棉用来连接电路板的接地点和金属外壳或部件,从而实现系统地电位的一致,降低电路板的电磁辐射。还有,手机和笔记本的屏幕、键盘也会用导电泡棉将ESD静电泄放到产品接地线上,提高产品抗静电的能力。
常用的导电泡棉有导电布泡棉、铝箔布泡棉以及全方位导电泡棉, 利用聚氨酯发泡或者聚乙烯交联方式使泡棉本体具有可压缩回弹的特性。其中,泡棉作为导电泡棉最重要的组成部分,泡棉按照孔结构来分有开孔发泡、半孔发泡、闭孔发泡、微孔发泡;按照材质可分为有机硅泡棉、聚氨酯泡棉、PE泡棉、PP泡棉以及亚克力泡棉等。其中,以聚氨酯泡棉应用的最为广泛。
由于电子产品的设计越来越轻薄,系统内部、部件之间的缝隙也越来越小,这就迫切需要一种可用于狭小缝隙内填充和导电屏蔽的新型超薄导电泡棉。并且,当导电泡棉在压缩到细小的缝隙里,需要其具有高的压缩性以及高的回弹性,在使用过程中,高的压缩性以及高的回弹性决定了导电泡棉是否能在多次或长时间压缩后能否保持原有的高度,是否还能继续提供减震缓冲以及良好应力搭接的特性,决定了导电泡棉的使用寿命。
常见的导电泡棉在长时间的使用过程中,其压缩性、回弹性会产生慢慢衰退的现象,特别是在湿热环境或反复压缩后。当导电泡棉压缩性和回弹性衰减,会造成电子产品潜在的短路风险,对电子产品的使用寿命和性能都会有一定的影响,是电子产品设计者非常担心的事情。因此,这就迫切需要一种新型超薄、高压缩性、高回弹性、防静电的导电泡棉。
中国专利申请号为CN201910462809.9公开了一种导电泡棉的制备方法,提供了一种具有良好的变形能力,高低温性能以及防静电效果良好的导电泡棉及其制备方法,但不具有超薄、高压缩性、高回弹性,具有一定的局限性。
发明内容
发明目的:为了克服以上不足,本发明的目的是提供一种新型超薄、高压缩性、高回弹性、防静电的导电泡棉及其制备方法,选择导电布、导电发泡压敏胶、离型膜这一结构,在导电发泡压敏胶中填入一定数量和大小的气泡,这些气泡均匀地分布且封锁在胶层里,使得胶体具有良好的弹性,这就类似胶层里填充了许多有弹性的小球,将泡棉、导电胶的功能结合于一体,导电泡棉的最小自然厚度降低到0.1mm,并保持高压缩率和高回弹性以及优异的高温高湿耐候性,制备方法简单,应用前景广泛。
本发明的目的是通过以下技术方案实现的:
一种新型超薄、高压缩性、高回弹性、防静电的导电泡棉,其特征在于,包括层叠设置的导电布、导电发泡压敏胶、离型膜;所述导电发泡压敏胶内填入若干气泡,所述气泡均匀地分布并且封锁在所述导电发泡压敏胶内部;所述导电发泡压敏胶,按质量份数计,由以下组分构成:基体树脂75~85份、导电填料15~25份、固化剂2~3份、抗氧剂2~3份、促进剂1~2份、偶联剂1~2份、消泡剂0.5~1份、流变助剂0.5~1份。
目前常见的导电泡棉多是以导电纤维布或金属箔类包裹内衬低压缩的聚氨酯泡棉而构成的FOF泡棉,以及直接对发泡的聚氨酯电镀形成X,Y,Z三轴导电的全方位导电泡棉。FOF泡棉和全方位导电泡棉,一般仅仅适用于电子电气机箱、液晶电视、笔记本电脑外壳、电信通讯机柜、电子产品接地屏蔽等,不适合湿热环境和较大压力的场合以及经常开关和有铰链的连接场合,因为FOF泡棉和全方位导电泡棉在湿热环境或反复压缩后,泡棉的压缩性和回弹性会急剧衰减。并且,FOF泡棉和全方位开孔型的导电泡棉目前最薄只能做到0.3 mm厚度,并且做到这么薄的泡棉还是通过对泡棉进行二次压缩得到的,这就牺牲了泡棉的压缩性,如果使用0.3mm的泡棉去填充0.05 mm的缝隙,可能造成系统结构部件因泡棉过大的反弹力而发生形变。
因此,本发明所述新型超薄、高压缩性、高回弹性、防静电的导电泡棉,不同于常见的泡棉-导电布-导电胶-离型膜这一结构,选择导电布、导电发泡压敏胶、离型膜这一结构,其中,导电发泡压敏胶是在导电发泡压敏胶中填入一定数量和大小的气泡,这些气泡均匀地分布且封锁在胶层里,使得胶体具有良好的弹性,这就类似胶层里填充了许多有弹性的小球,将泡棉、导电胶的功能结合于一体,这样就将导电泡棉的最小自然厚度降低到0.1mm,并保持高压缩率和高回弹性以及优异的高温高湿耐候性。
进一步的,上述的新型超薄、高压缩性、高回弹性、防静电的导电泡棉,所述基体树脂为双酚A环氧树脂、双酚F环氧树脂的一种或两种的混合;所述固化剂为酸酐、低分子量聚酰胺树脂、咪唑的一种或几种的混合;所述抗氧剂为AN 1135;所述促进剂为咪唑、 DMP-30的一种或两种的混合;所述偶联剂为KH560;所述消泡剂为改性聚硅氧烷溶液;所述流变助剂为气相二氧化硅。
进一步的,上述的新型超薄、高压缩性、高回弹性、防静电的导电泡棉,所述导电填料为球状微米银粉,平均粒径为2.8~3.0μm。
进一步的,上述的新型超薄、高压缩性、高回弹性、防静电的导电泡棉及其制备方法,包括以下步骤:

(2)导电发泡压敏胶的制备;
(3)导电布、导电发泡压敏胶、离型膜的复合成型。
在所述导电布的制备中,对PET纤维进行了表面化学镀银,制备金属银薄膜,得到导电布,所述导电布不仅导电性好、抗菌,还具有抗紫外和抗静电性能。
与其它制备导电布的方法相比,化学镀银是一种操作方便、工艺简单、镀层质量好的方法,它的传统工艺包括除油、粗化、敏化、活化、化学镀金属,敏化所用的氯化亚锡对环境有很大的危害性,活化中使用氯化把价格昂贵,使成本较高。所以,本发明所述的导电布的制备方法,将传统工艺简化、环保化、低成本化,至包括对PET纤维的除油、粗化、巯基改性,然后化学镀银。

(4)将导电填料与混合物C按比例物置于专用的搅拌器中搅拌均匀,并利用搅拌机充分搅拌后,填入若干气泡,得到所述导电发泡压敏胶。
球状微米银粉作为导电填料,能在导电发泡压敏胶形成更多导电通路从而提高电性能,导电性好,并且基体树脂与固化剂、促进剂、偶联剂、流变助剂等助剂以及球状微米银粉相协同,还提高导电发泡压敏胶的电学和力学性能。
