Abstract
The invention discloses a method for preparing matte release paper for adhesive tapes, which comprises the following steps: (1) laminating a laminating layer on the surface of one side of release base paper, and after the laminating layer is cooled, coating an adhesive layer on the surface of the other side of the release base paper so as to obtain a base material layer for standby; (2) coating a matte coating agent layer with thickness of 0.2-2 microns on the surface of a thin film layer, and carrying out illumination on the matte coating agent by using ultraviolet rays so as to obtain a matte coating, and coating a layer of release agent on the surface of a matte coating so as to obtain a matte release layer for standby; and (3) adhering the matte release layer to the base material layer. According to the invention, because the surface of the thin film layer is coated with a polyester matte coating firstly, after the polyester matte coating is processed, the surface has multiple uniform concave and convex structures, and then the surface is coated with a silicone release agent coating, the bottom surface of the silicone release agent coating seeps into the concave parts of the surface of the polyester matte coating, and the silicone release agent coating after being solidified is fixedly connected with the polyester matte coating through the concave parts, therefore, the bonding force is firmer and more reliable.
