Description

一种防静电压敏胶保护膜及其制备方法 技术领域
本发明涉及一种防静电膜及其制备方法, 尤其涉及一种防静电压敏胶保护 膜及其制备方法。
背景技术
目前保护膜被广泛应用于 LCD、 触摸显示屏的保护, FPC制造工序中的模 切加工及各 ΓΓ相关部件的加工工序。这些电子产品的应用场合一般都有防静电 的要求, 因为静电的存在不仅使产品表面容易吸附灰尘, 更加会影响触摸屏的 操作精准度, 或导致电子产品加工过程中线路击穿, 使产品失效。 因此, 有必 要对保护膜做静电防护处理。
目前国内类似技术很少, 国内实际大多采用进口日韩产品, 市场前景广 阔。 如 CN 101481589A公开了一种防静电耐高温压敏胶带及其制备方法, 该防 静电耐高温压敏胶带主要由基材和填涂于其上的三层涂层组成; 其中, 第一层 防静电层, 第二层为保护层, 依次填涂基材一面; 第三层为胶层, 填涂基材另 一面。 防静电层、 保护层和胶层的重量配比为 10〜65%: 0.01-25%: 30〜65%。 这种涂布方式得来的防静电层很容易在使用过程中被刮花, 影响防静电性能及 保护膜使用寿命。
也有一些采用内添加方式实现防静电功能, 如 CN 102453446A公开了一种 防静电薄膜, 该防静电薄膜包括基材和形成于基材上的涂层, 所述基材的表面 具有微孔, 所述涂层为树脂型压敏胶, 压敏胶中包含有纳米线形成的网状结构; 在压敏胶中添加纳米线, 通过纳米线形成网络结构, 进而实现导电功能。 但此 发明中所用的纳米线均为金属或金属氧化物纳米线, 这类纳米线活性大, 容易 被氧化, 失去导电功能; 更重要的是纳米线比表面积较大, 表面原子数多、 表 面能高、 长径比大, 属于热力学不稳定体系, 在溶液中分散时容易发生团聚, 或纳米线发生缠绕, 导致最终应用时失去纳米颗粒应有的特性和功能, 严重时 产品局部点电阻急剧下降甚至成为导体, 而其相邻周边会出现绝缘状态, 这样 在产品内会形成一个个电阻很小的 "孤岛" 。 因此有必要对纳米线进行必要的 前处理, 使其保持纳米材料应有的特性。
发明内容
本发明的目的在于提供一种防静电压敏胶保护膜。 本发明通过添加电解质 基聚合物导电物质, 通过电解质基聚合物导电物质与纳米线导电协同效应解决 压敏胶层整体防静电问题。 利用两类抗静电材料在硬化层中具有协同效应的特 点, 在很小添加量下即可实现最大的防静电效果。
为达上述目的, 本发明采用如下技术方案:
一种防静电压敏胶保护膜, 包括基材和涂布在基材上具有防静电功能的压 敏胶层, 所述的具有防静电功能的压敏胶层, 其防静电功能通过内添加抗静电 组合物包括电解质基聚合物导电物质和纳米线导电材料协同复配实现。
作为优选技术方案, 本发明所述的防静电压敏胶保护膜, 所述的抗静电组 合物按质量分数含有以下成分: 电解质基聚合物导电物质 0.05-20%, 例如为 0.08%、 0.3%、 0.9%、 1.5%、 3%、 7%、 11%、 15%、 19%等,纳米线 0.05-10%, 例如为 0.08%、 0.3%、 0.9%、 1.5%、 3%、 7%、 9%等, 有机硅压敏胶 5-80%, 例如为 8%、 14%、 20%、 26%、 33%、 39%、 44%、 51%、 59%、 63%、 66%、 71%、 77%等, 溶剂 10-90% , 例如为 8%、 14%、 20%、 26%、 33%、 39%、 44%、 51%、 59%、 63%、 66%、 71%、 77%、 82%、 88%等, 交联剂 0.05-10%, 例如为 0.08%、 0.3%、 0.9%、 1.5%、 3%、 7%、 9%等, 各组分质量分数之和为 优选地, 所述的抗静电组合物按质量分数含有以下成分
电解质基聚合物导电物质 0.1-10%
纳米线 0.1-3%
Figure imgf000004_0001
纳米线导电材料在压敏胶溶液固化过程中, 会形成互相交织的网络结构, 这些网络结构会随着压敏胶中溶剂挥发而向压敏胶层内部 "漂移", 导致压敏胶 内外两个表面网络结构密度降低, 从而防静电性能降低。 通常方法是增加纳米 线添加量, 但添加量增大后, 不仅成本升高, 更重要的是纳米线会影响到压敏 胶层的透明度。
本发明通过添加电解质基聚合物导电物质, 通过电解质基聚合物导电物质 与纳米线导电协同效应解决压敏胶层整体防静电问题。
当压敏胶涂于基材上发生热交联反应时, 由于电解质基聚合物导电物质在
Figure imgf000004_0002
联反应前期的溶剂挥发过程中, 电解质基聚合物导电物质会随溶剂向压敏胶表 面迁移, 导致压敏胶表面抗静电剂浓度大于中间部位浓度。
而压敏胶另一面 (即与基材 (如 PET表面) 表面粘附的一面), 由于电解 质基聚合物导电物质极性更大,与基材表面更容易形成较强的氢键或范德华力, 因此, 与基材粘附的一面导电物质浓度也会偏大。
以上两种作用导致电解质基聚合物导电物质在压敏胶层中存在明显的 "ΙΓ 型浓度梯度, 即压敏胶两端电解质基聚合物导电物质浓度偏高, 而中间浓度偏 小。
若只添加电解质基聚合物导电物质类抗静电剂或纳米线中的一种, 达到相 同抗静电效果时, 抗静电剂的添加量会明显增大很多。 本发明利用两类抗静电 材料在硬化层中具有协同效应的特点, 在很小添加量下即可实现最大的防静电 效果。
