Embodiment 1

[0032] In this embodiment, during the copying step, the square plastic material sheet material with a side length of 0.2 mm and a thickness of 0.01 mm is dispersed with water at a concentration of 0.01% to form a uniform water dispersion, and the diameter is passed through a plastic material with a diameter of 1.2 cm. At a flow rate of 1500ml / min, the pipeline is released into the slurry in the mesh tank through the release port. The release port is 3.0cm lower than the surface of the liquid level in the network tank. With the forming of the wet paper sheet, the sheet material is embedded in the paper by the pulp fiber.

Embodiment 2

[0034] In this embodiment, during the papermaking step, the circular paper sheet material with an area of ​​6.0 square millimeters and a thickness of 0.03 mm is dispersed with water at a concentration of 0.2% to form a uniform water dispersion, and passed through a diameter of 1.6 cm. The plastic pipe is released into the mesh tank slurry through the release port at a flow rate of 2000ml / min. The release port is 2.0cm below the liquid level surface of the network tank. With the forming of the wet paper sheet, the sheet material is buried into the paper by the pulp fiber.

Embodiment 3

[0036] In this embodiment, during the copying step, an irregular metal sheet material with an area of ​​3.0 square millimeters and a thickness of 0.075 mm is dispersed with water at a concentration of 0.5% to form a uniform water dispersion. According to the flow rate of 1200ml / min, the plastic pipe is released into the slurry of the mesh tank through the release port. The release port is 2.0cm below the surface of the liquid level of the network tank. With the forming of the wet paper sheet, the sheet material is embedded in the paper by the pulp fiber .

Abstract

This invention discloses an anti-forgery paper containing flap materials and its manufacturing method. It includes: the conical procedure, the stiurry compounding procedure, the pulping procedure, the sizing procedure and the artifactitious procedure. The pulping procedure includes adding the flap materials in the paper pulp. The flap materials mix with the paper pulp to form the wet pages and then being dried. Since this invention adopts the above techniques and has flap materials which are covered with the pulp fiber on the two sides, so it is convenient for the public to recognize and does not affect the quality of printing.

Description

technical field [0001] The invention relates to a manufacturing method of anti-counterfeiting paper such as banknote paper, security paper, passport paper, bill paper, certificate paper, etc., in particular to a kind of anti-counterfeiting paper containing sheet material and its manufacturing method. Background technique [0002] At present, the known anti-counterfeiting paper is generally made by adding anti-counterfeiting materials such as security threads and colored fibers during paper manufacturing, but the anti-counterfeiting paper is easy to forge, and the printing performance is not good enough. Contents of the invention [0003] The invention aims at overcoming the defects of the existing anti-counterfeit paper and provides a kind of anti-counterfeit paper containing sheet materials with good printing adaptability and simple process and a manufacturing method thereof. [0004] The technical measures taken by the present invention are: a method for manufacturing an...
