Method for preparing matte release paper for adhesive tapes

胶带用雾面隔离纸的制备方法

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.
本发明公开一种胶带用雾面隔离纸的制备方法,步骤包括:在离型纸原纸的一侧表面淋膜一层淋膜层,冷却后在所述离型纸原纸的另一侧表面涂布一层胶粘剂层得到基材层,备用;在一薄膜层的表面涂布一层厚度为0.2~2微米的雾面涂层剂;采用紫外线对所述雾面涂层剂进行照射得到雾面涂层,再在所述雾面涂层的表面涂覆一层离型剂得到雾面离型层,备用;(3)将所述雾面离型层和所述基材层两者贴合。由于本发明首先对薄膜层的表面涂布聚酯雾面涂层,经处理后表面具有若干均匀凹凸结构,然后在此表面涂布硅离型剂涂层,硅离型剂涂层的底面在液态下渗入所述聚酯雾面涂层表面的凹缺处,硅离型剂涂层在凝固后通过凹缺与聚酯雾面涂层固定相连,因此,结合力更加牢固、可靠。
