本实施例中，该基础聚合物、交联剂、填充剂、粘结促进剂、催化剂和增塑剂的具体成分可参考上述防静电胶的实施例，此处不再赘述。所述预设配比通常根据实际需求而定，其可以根据重量份数选取，其中当所述基础聚合物包括端乙烯基硅油复配物，所述交联剂包括含氢硅油，所述填充剂包括白炭黑和石英粉，所述交联剂包括四甲氧基硅烷，所述粘结促进剂包括3- 氨丙基三乙氧基硅烷，所述催化剂包括正钛酸四异丙酯，所述增塑剂包括二甲基硅油时，所述乙烯基硅油复配物、白炭黑、石英粉、二甲基硅油、四甲氧基硅烷、正钛酸四异丙酯以及 3- 氨丙基三乙氧基硅烷之间的重量份数比值可以为100：2： 2：10：6：3：2。
实际制备过程中，可以先按重量份选取端乙烯基硅油复配物100 份(1000 mPa·s)、白炭黑和石英粉各2份、二甲基硅油10 份(10cps)加入搅拌釜中，真空条件下高温脱水0.5小时，冷却至室温，再加入四甲氧基硅烷6 份、正钛酸四异丙酯3 份和3- 氨丙基三乙氧基硅烷2 份，将它们真空混合30min至均匀，得到防静电胶。通过测试，该防静电胶的体电阻可达1014Ω.cm，较现行量产的Tuffy防湿绝缘胶要高出1~2个数量级，大大提高了防静电能力。
此外，请参见图2，本发明实施例还提供一种液晶显示装置10，包括阵列基板11、彩膜基板12、位于所述阵列基板11和彩膜基板12之间的液晶层13、以及将所述阵列基板11和彩膜基板12封装成液晶盒（图中未示出）的封框胶14，所述封框胶14的至少一个侧壁外表面覆盖有上述任一种防静电胶15。
具体的，所述阵列基板11为TFT（Thin Film Transistor Array Substrate，薄膜晶体管阵列基板），所述阵列基板11和彩膜基板12相对设置，所述阵列基板11的表面尺寸不小于所述彩膜基板12，比如所述阵列基板11相对于彩膜基板12可以外露0.05~0.1mm，该防静电胶15可以环绕封框胶14进行设置，以确保外部静电不能从封框胶14进入液晶盒内部，对内部电路造成影响。进一步地，在垂直于所述阵列基板11的方向上，所述防静电胶15的厚度可以大于对应封胶框14的厚度，但其上表面通常不超出彩膜基板12表面。
本发明实施例所述的防静电胶及其制备方法、以及液晶显示装置，其中所述防静电胶包括基础聚合物、交联剂、填充剂、粘结促进剂、催化剂和增塑剂，所述基础聚合物包括端乙烯基硅油复配物，所述填充剂包括白炭黑、石英粉、碳酸钙、氧化铝、氧化锌、二氧化钛、氢氧化铝、氢氧化镁、炭黑以及铁黑中的至少一种，所述交联剂包括含有烷氧基基团的硅氧烷化合物，所述粘结促进剂包括含有氨基、氯基、环氧基、酰氧基或异氰酸酯的基硅烷，所述催化剂包括钛酸酯螯合物，所述增塑剂包括含氢硅油。上述防静电胶具有良好的抗静电能力，通过在液晶显示装置中封框胶的至少一个侧壁外表面上设置所述防静电胶，可以有效阻挡外部静电进入液晶显示器内部，提高液晶显示器防静电效果。
以上所述仅为本发明的较佳实施例而已，并不用以限制本发明，凡在本发明的精神和原则之内所作的任何修改、等同替换和改进等，均应包含在本发明的保护范围之内。
