Problems solved by technology

Chinese Patent (Application No.) 96104762.3 An anti-counterfeiting penetrating atomic printing oil and its preparation method, Chinese Patent (Application No.) 98119855.4 Multifunctional anti-counterfeiting printing ink manufacturing method, Chinese Patent (Application No.) 99125133.4 long and short wave anti-counterfeiting printing ink and anti-counterfeiting ink, etc., mainly It is to mix luminescent phosphor powder into the printing oil, then irradiate the printed matter with ultraviolet light, and use the fluorescent reverse signal to judge and identify its authenticity. The disadvantage of this technology is that this technology only detects whether there is any Fluorescent materials, such a technology is easy to be imitated, it only needs to be mixed with fluorescent powder when making printing ink, and it is easy to be forged
Japanese patent JP56115288 introduces a kind of ink pad made of temperature-reversible color-reversing material, and the printed matter stamped with this ink changes color when heated, so as to achieve the purpose of anti-counterfeiting. The disadvantage of this technology is that imitators are making ink When mixed with temperature-changing materials, it is still easy to be forged
Chinese patent (application number) 94117784.X is a kind of magnetic anti-counterfeiting ink, and its anti-counterfeiting function seems single
The disadvantage of this technology is to detect the strength of the magnetic field, because many reasons in daily life will change the strength of the magnetic field in the printed matter, so the strength of the detected magnetic field is used to judge the reliability of identifying the authenticity of the printed matter is not high
Some of the existing printing oil anti-counterfeiting technologies listed above are relatively simple and easy to be imitated, and some have more complicated production processes but single anti-counterfeiting means.

Embodiment 1

[0030] 5nm r-Fe 2 o 3 Carry out magnetization. and then converted to r-Fe by electromagnetic 2 o 3 Enter the password information (the sound of D key 3 in the range), so that the r-Fe of each particle 2 o 3 Both of them memorize the password information with the same content. Take r-Fe containing password information 2 o 3 20 parts (weight ratio, the same below), 15 parts of 30 nanometer infrared phosphor, 10 parts of 50 nanometer ultraviolet long-wave phosphor, 10 parts of 50 nanometer ultraviolet short-wave phosphor, 10 parts of oleic acid, 20 parts of gold red, rosin modified phenolic 50 parts of resin are mixed and processed into colorant. Take 39 parts of colorant, 60 parts of engine oil, 1 part of OP-10, and 1 part of anti-aging agent DOD, mix them evenly in a mixing kettle, and then grind them to a fineness of 14μ with a three-roller machine to obtain stamping ink.

Embodiment 2

[0032] 20 nm of CrO 2 Carry out magnetization. and then converted to CrO by electromagnetic 2 Input the password information (the tone of D key 4 in the range), so that the CrO of each particle 2 Both of them memorize the password information with the same content. Get CrO containing password information 2 30 parts (weight ratio, the same below), 13 parts of 5nm infrared phosphor, 9 parts of 30nm ultraviolet long-wave phosphor, 10 parts of 30nm ultraviolet short-wave phosphor, 15 parts of oleic acid, 22 parts of peacock blue, castor oil modification Alkyd resin - long oil 33 parts are mixed and processed into colorants. Take 40 parts of coloring material, 58 parts of castor oil, 1 part of hydroquinone and 1 part of anti-aging agent AP, mix them evenly with a colloid mill, and then grind them with a three-roll machine to a fineness of 10 μ, that is, the printing ink for stamping.

Embodiment 3

[0034] 50nm Co-Fe 2 o 3 Carry out magnetization. Then by electromagnetic conversion to Co-Fe 2 o 3 Enter the password information (the sound of D key 5 in the range), so that the Co-Fe of each particle 2 o 3 Both of them memorize the password information with the same content. Fetch Co-Fe containing password information 2 o 3 25 parts (weight ratio, the same below), 13 parts of 5nm infrared phosphor, 9 parts of 30nm ultraviolet long-wave phosphor, 10 parts of 30nm ultraviolet short-wave phosphor, 11 parts of oleic acid, 22 parts of phthalocyanine green, castor oil modified Alkyd resin - long oil 42 parts mixed and processed into colorant. Take 36 parts of colorant, 62 parts of didecyl terephthalate, and 2 parts of sodium lauryl sulfate. Mix them evenly with a colloid mill, and then grind them with a three-roller machine to a fineness of 11 μ, which is the printing ink for stamping.
