Description
技术领域
本发明涉及超润滑薄膜的制备领域，特别涉及一种透气性超润滑薄膜。
背景技术
DLP激光成型技术是3D打印技术的一种，是使用高分辨率的数字光处理器(DLP)投影仪来照射固化液态光聚合物的成型技术，其采用光敏树脂为打印材料，具有打印速度快、成型精度高、打印分别率高、成型件表面光滑等特点，可以与注塑成型件相媲美。
但是DLP在进行打印过程中，工作平台需不断地上下进行移动，使已经固化的成型件与树脂槽底部的透明薄膜分离开来，树脂槽中的树脂重新进行充满底部。然而在这个过程中，固化树脂层与透明薄膜发生撕扯，并随着打印的进行不断地反复发生，这容易导致成型件产生变形或透明薄膜的脱落。
发明内容
本发明的主要目的在于克服现有技术的缺点与不足，提供一种透气性的超润滑薄膜。此薄膜具有透气性、超润滑性等特性。
为实现上述目的，本发明提供了如下技术方案：
一种透气性超润滑薄膜，其特征在于：所述透气性超润滑薄膜包括薄膜基层、润滑表面层和粘结层，其中薄膜基层和粘结层密排有直径为纳米级的渗透孔。
进一步地，所述润滑表面层是通过在薄膜基层上表面上制备微纳复合结构，再进行疏水化处理，最后注入润滑液以形成润滑表面层。
进一步地，所述粘结层为聚氨酯粘接剂。
与现有技术相比，本发明具有如下有益效果：
(1)本发明具有透气性和超润滑双重功能。
(2)本发明渗透孔为纳米级别，可以达到防水透气地作用。
(3)本发明具有通过改变渗透孔的尺寸大小从而改变透气性程度的特点。
(4)本发明具有通过改变薄膜基层表面的纳米结构从而改变润滑性能的特点。
(5)本发明原理简单，制备容易，生产成本较低等特点。
(6)本发明适用于抗冰，防雾，防油污，防污染，医疗，3D打印等多种领域。
附图说明
图1为本发明一种透气性超润滑薄膜的结构示意图；
图2为本发明一种透气性超润滑薄膜的内部结构示意图。
图中：1、润滑表面层；2、薄膜基层；3、粘结层；4、纳米复合结构；5、渗透孔。
具体实施方式
为使本发明实现的技术手段、创作特征、达成目的与功效易于明白了解，下面结合附图，进一步阐述本发明。
图1和图2出示本发明一种透气性超润滑薄膜的具体实施方式：该透气性超润滑薄膜包括润滑表面层1、薄膜基层2和粘结层3，且薄膜基层2和粘结层3密排有大量渗透孔5，渗透孔5的直径为纳米级，具有防水透气功能。
结合图1和图2，润滑表面层1是通过物理和化学方法在薄膜基层表面上制备微纳复合结构，再进行疏水化处理，最后注入润滑液形成的润滑表面层。薄膜基层2具有透光性好、耐磨性好、良好的力学性能等特性。粘结层3为聚氨酯粘接剂，粘结效果好，且渗透性好。
需要说明的是，本发明为一种透气性超润滑薄膜，润滑表面层1为微纳多孔结构，其中微米孔孔径1～2μm，纳米孔150～250nm。且超润滑表面透明，其可见光透过率接近于透明玻璃。
以上所述实例，仅为本发明较佳的具体实施方式，但本发明的保护范围并不局限于此，其他任何在未背离本发明原理，根据本发明的技术方案及其发明构思加以替换、改变、组合、简化等的等效置换方式都落入要求保护的本发明范围内。本发明要求保护范围由所附的权利要求书及其等效物界定。
