Abstract
The invention relates to a preparation method of a matte release paper. The method includes: laminating a laminated film layer on one side surface of a release paper base paper by a laminating machine, then conducting cooling; coating an adhesive layer on the other side surface of the release paper base paper, and attaching a film layer on the surface of the adhesive layer; coating a matte coating agent layer with thickness of 0.2-2 micrometers on the surface of the film layer; using ultraviolet rays to illuminate the matte coating agent to make a multifunctional acrylate monomer undergo a polymerization reaction under the action of an initiator so as to obtain a matte coating; and coating a layer of a release agent on the surface of the matte coating. According to the method provided in the invention, as the polyester matte coating is firstly coated on the surface of the film layer, the treated surface has several uniform concave-convex structures, and then the silicon release agent coating is coated on the surface. Under a liquid state, the undersurface of the silicon release agent coating seeps into the concave parts on the polyester matte coating surface. After solidification, the silicon release agent coating is fixedly connected to the polyester matte coating through the concave parts. Therefore, the bonding force can be firmer and more reliable.
