The invention belongs to technical field of polymer materials, and in particular to one kind is exempted to apply silicon release film and preparation method thereof.The release film has the three-decker of the first functional layer, intermediate layer and bottom or the first functional layer, intermediate layer and the second functional layer, using homopolypropylene and calcium carbonate masterbatch as primary raw material, the three-layer type release film provided, structure is compacted easily peelable, off-type force is small on the basis of ensureing not influencing glue surface characteristic, effect is more preferable, solves the problems, such as that the release transfer of conventional light release film is generally higherï¼›And eliminate and apply silicon process, cost-effective, process is not related to poisonous, volatile solvent etc., environmentally safe, reduces the harm to operating personnel. |
