Abstract
The invention relates to magnetic anti-forgery ink powder. The magnetic anti-forgery ink powder comprises 40 to 55 mass percent of polyester resin, 45 to 50 mass percent of acicular high-coercivity magnetic powder, 2 to 8 mass percent of metallic salicylic complex, 3 to 6 mass percent of polypropylene wax and 1 to 1.5 mass percent of hydrophobic silica. The magnetic anti-forgery ink powder has the advantages that: the acicular high-coercivity magnetic powder is added into an ink powder formula to prepare special magnetic anti-forgery ink powder; and personal checks can be printed by using a laser printer or a light-emitting diode (LED) printer.
Description
Technical field
The present invention relates to magnetic China ink character recognition (MICR) technology, particularly a kind of magnetic anti-counterfeit ink powder.
Background technology
In the magnetic printing, magnetic ink character identification (MICR) is a kind of legitimacy or Promethean technology that is used to verify paper document, especially check is checked, this the very sensitive special ink of magnetic field force be can be used to write some character in original document, and detection information can be comprised in these magnetic force characters, and the scanning recognizer of available dedicated gives the branch evident.Mainly use printing ink as developing material in the existing MICR technology, yet print the flowability of printing ink is had relatively high expectations, printing ink is convenient to carry in use, is easy to occur obstruction and prints head; And printing ink is in that to be printed onto on the file drying time long, and stickability is bad, easily rubs off.
Summary of the invention
The problem to be solved in the present invention is to make a kind of special magnetic anti-counterfeit ink powder, uses the printed product of this ink powder can be used for magnetic ink character identification.
The present invention for achieving the above object, the technical scheme of being taked is: a kind of magnetic anti-counterfeit ink powder, it is characterized in that: comprising: vibrin, needle-like high-coercive force magnetic, metal salicylate complex compound, polypropylene wax, hydrophobic silica, the mass percent of concrete component is: vibrin 40～55; Needle-like high-coercive force magnetic 45～50; Metal salicylate complex compound 2～8; Polypropylene wax 3～6; Hydrophobic silica 1～1.5.
Needle-like high-coercive force magnetic is the acicular crystal less than 1um, and is very easily evenly distributed in magnetic field, thereby obtains the residual magnetic of comparison.
The invention has the beneficial effects as follows: needle-like high-coercive force magnetic is joined in the ink powder prescription, make the special magnetic anti-counterfeit ink powder, can utilize laser printer or LED printer prints personal cheque.
Embodiment
Embodiment 1:
The each component mass percent is: vibrin 45, needle-like high-coercive force magnetic 45, metal salicylate complex compound 5, polypropylene wax 4, hydrophobic silica 1.
Preparation technology is: after vibrin, needle-like high-coercive force magnetic paint, metal salicylate complex compound, polypropylene wax are mixed in proportion, mixing through the high precision mixing facilities, be pressed into sheet, broken through coarse crushing and micro mist again, grading system becomes classification product semi-manufacture, classification product granularity is controlled at 6-10 μ m, the classification product fully mixed 5-15 minute after adding hydrophobic silica, removed the aggregate of the trace that produces in mixed process again through 200 mesh sieves, and packing forms formal product.The all images sample manuscript all can obtain special electric signal through the scanning of magnetic ink character and graphic identification sensor.
Embodiment 2:
The each component mass percent is: vibrin 43, needle-like high-coercive force magnetic 50, metal salicylate complex compound 3, polypropylene wax 3, hydrophobic silica 1.
Its preparation technology is with embodiment 1.
The all images sample manuscript all can obtain special electric signal through the scanning of magnetic ink character and graphic identification sensor.
