Non-silicon matte double-sided release film and preparation process

The embodiment of the invention provides a non-silicon matte double-sided release film and a preparation process. The release film comprises a non-silicon release agent layer, a base material layer and a matte non-silicon release agent layer which are sequentially connected. Silicone oil or a silicon-containing release agent is not used, and the production cost is reduced while the matte effect isachieved; and meanwhile, the requirements of electronic material manufacturers on the performance of various aspects of the release film can be met, and the problem that the current matte release film can cause silicon transfer due to the use of silicone oil or the silicon-containing release agent, and the glue performance or surface printing character performance is influenced is solved. 本发明实施例提供了一种非硅哑光双面离型膜及制备工艺，该离型膜包括依次相连的非硅离型剂层、基材层以及哑光非硅离型剂层，未使用硅油或含硅离型剂，在具有哑光效果的同时降低了生产成本，同时还可以满足电子材料生产厂家对离型膜各方面性能的需求，解决了目前的哑光离型膜因使用硅油或含硅离型剂会造成硅转移，影响胶性能或表面印刷字符性能的问题。
