The present invention belongs to the technical field of electrolytic copper foil production, and the present invention provides an additive for ultra-thick electrolytic copper foil, an ultra-thick electrolytic copper foil and a preparation process thereof. The additive comprises the following components: aspartic acid, 2-mercaptopyridine, gelatin, sodium polydisulfide dipropane sulfonate, polyvinyl alcohol and water. The present invention also provides a preparation process for ultra-thick electrolytic copper foil using the above-mentioned additive, comprising the following steps: S1, adding a copper block to a sulfuric acid solution for reaction to generate a copper sulfate electrolyte; S2, adding the additive to a copper sulfate solution for electrolysis to produce a super-thick electrolytic copper foil. The ultra-thick electrolytic copper foil prepared by the present invention not only ensures its own thickness, but also ensures its own strength. It will not easily become loose due to uneven sticking due to excessive thickness of the body, thereby extending its service life and meeting the needs of high-end circuit boards.

The utility model discloses a multilayer film structure based on bright surface paper, including the transparent layer, bright surface paper, adhesive layer and double glue base paper of up and down distribution, the transparent layer includes the first transparent adhesive film and second transparent adhesive film that different anti -fake marks are printed, and the first transparent adhesive film and second transparent adhesive film all are glued on the bright surface layer, and the anti -fake mark of both is not blocked each other, and the adjacent place of first transparent adhesive film and second transparent adhesive film exists the overlapping area, and both fixed connection. The utility model discloses through gluing the first transparent adhesive film and second transparent adhesive film on the bright surface layer of bright surface paper, does not influence the original luster and aesthetic feeling of bright surface paper, and through the anti -fake mark of first transparent adhesive film and second transparent adhesive film, increases the anti -fake function, in addition, because first transparent adhesive film and second transparent adhesive film fixed connection, improve the bonding strength of first transparent adhesive film and second transparent adhesive film and bright surface paper, and the combination of different anti -fake marks can improve the difficulty of counterfeiting, and easily consumer identification.
