Embodiment Construction

[0022] The present invention will be described in detail below in conjunction with the accompanying drawings: the local positioning anti-counterfeiting multi-color cardboard of the present invention, it at least consists of a face pulp 1, a core pulp 2 and a base pulp 3 to form a multi-layer pulp through a paper machine to make a cardboard, Fig. 1 Shown is five layers of slurry. In other embodiments, the multi-layer slurry has at least three layers, including at least one layer of surface slurry 1, at least one layer of bottom slurry 3, at least one layer of core slurry and so on. In the surface paste and / or base paste of multi-layer paste, at least one paste layer is positioned and sprayed with at least one pigment and is compounded between the multi-layer paste; and in the face paste and / or base paste of multi-layer paste at least one At least two pigments are positioned and sprayed in the paste layer and are compounded between multiple layers of paste.

Abstract

The invention relates to a positioning colorful false-proof white paper plate and relative production. The invention at least utilizes the face pulp the linear pulp, the pulp corn and the bottom pulp to obtain the multilayer pulp to be processed into the paper plate via the paper machine. The invention is characterized in that the face pulp and/or the bottom pulp is positioned and plated with at least one dye to be combined between the multilayer pulps; the face pulp and/or bottom pulp is positioned plated with at least two dyes combined between the multilayer pulps; the multilayer pulp has at least three layers, while the corn pulp is plated with at least one dye combined between interlayer pulp. And the production comprises the productions of face pulp, corn pulp and bottom pulp, the papering on the paper machine, drying, and plating, calendaring, and coiling. In the papering process, the dye is plated on the multilayer pulp, face pulp or the bottom pulp between several mesh cages of paper machine, and via the dye position, the invention designs special baffle plate to realize positioning and separating, to hold the dyed part on the pulp and separate the part without dye and position the dye. Therefore, the invention has false-proof function, simple recognition, low cost and high quality.

Description

technical field [0001] The invention relates to a local positioning anti-counterfeiting multi-color cardboard and a manufacturing method thereof, which belong to a kind of anti-counterfeiting special paper and a papermaking process. Background technique [0002] Coated white paperboard is a kind of paperboard. Due to its exquisite surface treatment, it is suitable for various color printing, so it is a good material for manufacturing various packaging boxes, high-end clothing liners, notebook covers, medicine boxes, cosmetic boxes and other products. This kind of coated white board is generally made of face pulp, liner pulp, core pulp and bottom pulp by paper machine forming single-sided white board, and then coated on the surface. The specific production process is: 1. Flour production : Wood pulp—chain plate conveyor—hydraulic pulper—high frequency fiber refiner—conical refiner—double disc refiner—filler and starch in the pulp tank—pulp distribution box—paper machine pulp ...
