Abstract
The present invention discloses a preparation method for antistatic antibacterial release paper. The method is characterized bu comprising the following steps: coating a surface on one side of raw release paper with a laminated layer by using a laminating machine; coating a surface on the other side with an adhesive layer; coating a surface of the adhesive layer with a film layer; after the film layer is coated with an antistatic layer, performing corona-pretreatment and super-calendering; coating a surface of the antistatic layer with a release agent to obtain a release layer; coating a surface of the release layer with an antibacterial agent to obtain an antibacterial layer; drying the antibacterial layer at 20-25 DEG C to obtain antistatic antibacterial release paper. The preparation method provided by the invention is simple and feasible. By using palladium calcium carbonate as a catalyst, higher production efficiency is achieved without toxic side effects. Compared to a noble metal catalyst, the palladium calcium carbonate is more advantageous. By adding a non-toxic organic antibacterial agent to the surface of the release paper, the release paper can have an antibacterial capability and is applicable to the fields of food, pharmacy and chemical engineering. The antistatic antibacterial release paper prepared by the invention has not only a high strength capability, a high stretch capability, a high antibacterial capability but also a high antistatic capability.
